Hi. I wrote the following paper. I understand that I claim the most fundamental law of science to be incorrect. Please give me some *constructive* feedback. ---------------- NEW SCIENCE - redefining science from the roots CONTENTS: (1) Inventions Two inventions that propel themselves "internally". A third invention which can be set up to be a perpetual motion, free-energy device. (2) Conservation of Energy Two reasons why the Law of Conservation of Energy is wrong. (3) Bird & Earth An example which demonstrates that the Law of Conservation of Energy is wrong. (4) Dark Energy A hypothesis that the effects of "dark energy" (the acceleration of the expansion of the universe) is instead caused by gravitational forces. (5) Work Redefining work intuitively, with the knowledge of that the Law of Conservation of Energy is wrong. (6) Electricity An attempt at explaining electricity with the knowledge of "(5) Work". *best read in a size 10, fixed-size font. -\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\- -|-|-| (1) INVENTIONS -|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|- -/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/- Inventions: 1) The "Seesaw" Newton Motor 2) The "Simple" Newton Engine 3) The "Gravitational-density" Dynamo The first two inventions work on Newton's law that "every action has an equal and opposite reaction." The idea is to harness the "action" and eliminate the "reaction", or convert the "reaction" into something useable. The two inventions work without affecting the environment. That is, they don't need a road to push off of like cars, they don't have to push air like planes or spew out gases like space shuttles. They propel themselves *internally*. That is, you can put a box around the entire device and the box would move, and nothing would enter or exit the box, and the device itself wouldn't react with the environment that comes inside the box. It only reacts to the environment in the box which it creates, which it uses to propel itself. The third invention is a dynamo which creates electricity. It can be set up to be a perpetual motion, free-energy device. (must be read using a "fixed-size font" to view diagrams) -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- =-=-=-1) The "Seesaw" Newton Motor=-=-=-=-=-=-=-=-=-=-=-= -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Top view: M1a---M2a <--front electromagnets m1 \ \ /\ \ || o <--seesaw || \ forward \ \ m2 M1b---M2b <--back electromagnets Ideally, "M1a", "M1b", "M2a", "M2b", "m1", "m2" are all electromagnets. (Some of the electromagnets can be changed into permanent magnets where it is deemed fit.) "M1a", "M1b", "M2a", and "M2b" are fastened to the base, while "m1" and "m2" are connected to a "seesaw" whose pivot ("o") is connected to the base. (It is possible to construct this without the back electromagnets). The way this invention works is somewhat hard to understand. Here is a simplified version: When "M1a" and "m1" are nearly touching an electric current is sent through "M1a", "M1b", and "m1". "M1a" should repel "m1" while "M1b" should attract "m1". Thus, both "M1a" and "M1b" will experience a force in the forward direction, while the seesaw swings around bringing "m2" close to "M2a". As "M2a" and "m2" are close now, an electric current will pass through "M2a", "M2b", and "m2". "M2a" should repel "m2" while "M2b" should attract "m2". Again, "M2a" and "M2b" will experience a force in the forward direction while the seesaw swings back to its starting position to repeat the cycle. Since all the electromagnets that are connected to the base experience a force in the forward direction, the entire device will be propelled forward as the seesaw keeps swinging about. The above explanation of the workings of the Seesaw Newton Motor is incomplete. One should understand that the very first swing of the seesaw does not create enough energy to propel the device. On the other hand, after that first swing, the momentum of the seesaw greatly increases the amount of repulsive force experienced between the electromagnets on the swing and the ones in front. To use an analogy, consider yourself motionless and on rollerblades. The very first swing is like throwing a basketball; you won't move much in the opposite direction. All the swings after the first one is like pushing against a wall; you will move in the opposite direction. If, as the seesaw swings, "m1" hits "M1b" or "m2" hits "M2b", then the collision will slow the forward motion of the entire device. Thus, such a collision is undesirable. One could avoid this collision by keeping the back electromagnets far enough from the seesaw (as I have in the diagram), or a brake could be installed in the pivot to stop the complete swing of the seesaw (by friction). It may seem that if the seesaw swings so hard that "m1" hits "M1a" or "m2" hits "M2a" then the force of the collision will cause the base to experience a force in the forward direction. This is wrong. Only the "forward momentum" of the seesaw will "push" the base forward. However, when the seesaw hits the front electromagnets, the entire seesaw will stop moving and the "backward momentum" of the electromagnet will be conveyed to the base via the pivot. One could avoid this by changing the seesaw by bending it so as to make a 90 degree corner where it attaches with the pivot. Then, connect both ends of the seesaw together; ideally, the connection should be a curve. After doing that, the seesaw will undoubtedly look more like a quarter-slice of pizza. In such a configuration, most of the "backward momentum" will swing around becoming "forward momentum". A better, but more complicated, way to avoid the "backward momentum" of the electromagnets being conveyed to the base is by ensuring that the electromagnets are activated such that the seesaw never has a chance to collide with any of the forward electromagnets. In such a case, input sensors would need to be used so that the electromagnets could be perfectly timed to avoid collisions. -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- =-=-=-2) The "Simple" Newton Engine-=-=-=-=-=-=-=-=-=-=-= -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- The Simple Newton Engine is a cylinder with a piston in it. The piston may require wheels to move inside the cylinder. STEP 1: \-----------\-----------\-----------\-----------\ The idea is to force the piston in the backward direction, down the cylinder. Since every action has an equal and opposite reaction, the cylinder will then experience a force in the forward direction. This force is ideally created by using electromagnets. Let us say that there is an electromagnet on the piston which repels the magnet. (Also, one could make this similar to a Linear Induction Motor, with the piston as the projectile.) Side-view (cross-section): | ___cylinder | || | \/ |/------------- || #*| <--magnet ("*") forward --> |\------------- | /\ | ||__piston ("#") | |<--start /-----------/-----------/-----------/-----------/ STEP 2: \-----------\-----------\-----------\-----------\ The electromagnet on the piston is activated. Thus, the piston, which is repelled by the magnet, moves down the cylinder, as the magnet and the cylinder accelerate forward. | ___ The magnet and the cylinder | || move "forward"... | \/ --> | /------------- | | # *| | \------------- | /\ <-- | ||__ ...as the piston moves "back" | through the cylinder |<--start /-----------/-----------/-----------/-----------/ STEP 3: \-----------\-----------\-----------\-----------\ In fractions of a second, the piston will have arrived at the "back" of the cylinder. The piston must be stopped before it slams into the back of the cylinder, because if it does, then the energy of the piston will cancel out the forward velocity that the cylinder has gained. So, the energy of the piston must be removed (by friction, e.g. brakes on the wheels) or harnessed (a method which converts the "negative" energy of the piston into something useable). If friction is used to stop the piston, the friction must cause the piston to lose velocity in decrements; should the brake make the piston stop abruptly, then the "negative" momentum of the piston will be transferred to the cylinder. | | | | /------------- | | # *| | \------------- | /\ | ||__The piston must be stopped before | it hits the "back" of the cylinder |<--start /-----------/-----------/-----------/-----------/ STEP 4: \-----------\-----------\-----------\-----------\ When the piston has reached the end, and has been brought to a stop, it must then be moved to the front of the cylinder, perhaps by hooking it to a chain which is being pulled by a motor. Perhaps, the piston can be removed from the cylinder when it is being transferred to the front, and thus leave the cylinder free so that another piston can "shoot" through it. | | | | /------------- | |# *| | \------------- | | | |<--start /-----------/-----------/-----------/-----------/ Return to STEP 1: \-----------\-----------\-----------\-----------\ The piston has been returned to the front. Overall, the engine has moved and gained velocity. Now it is ready to restart at STEP 1. | | | | /------------- | | #*| | \------------- | | | |<--start /-----------/-----------/-----------/-----------/ -------------------------------------------------- Magnetic Propulsion for the "Simple" Newton Engine: Cross-section: mmmmmmmmmmmmmmmmmmmm mmmmm ____ mmmmm <-- "m" are magnets mmmm /WWWWWW\ mmmm mmm /W/ \W\ mmm mm /W/ mm \W\ mm m W mmmm W m <-- "W" is a wire coil m |W| mmmmmm |W| m m |W| mmmmmm |W| m m W mmmm W m X forward mm \W\ mm /W/ mm (into paper) mmm \W\____/W/ mmm mmmm \WWWWWW/ mmmm mmmmm mmmmm mmmmmmmmmmmmmmmmmmmm If the magnets "m" are arranged such that the field is perpendicular to the wire, and if a current is set up in the wire coil, then the wire coil will either move forward or backward. This could be applied to the Simple Newton Engine. The wire coil would be the "piston" and the magnets would be part of the "cylinder". -------------------------------------------------- It should be noted that the Simple Newton Engine creates a small amount of force for a relatively minute amount of time. In my mind, it would only be effective if many are used simultaneously. For example, I imagine that it wouldn't be too hard for the Simple Newton Engine to have a burst of 5N for a tenth of a second. Building a unit of ten thousand of such Newton engines would create a combined force of 5000N, assuming that the engines can "reload" in 0.9 seconds. The real problem is getting a good force-to-mass ratio (acceleration); if you can get acceleration greater than 10 m/s² then you can pretty much launch any vehicle, no matter how massive, into space. If the vehicle is really massive, then all you need to do is add more individual engines to the unit, and eventually it should lift off the ground. If such high accelerations cannot be made, then I'm sure this invention can compete with ion propulsion. -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- =-=-=-3) The "Gravitational-density" Dynamo-=-=-=-=-=-=-= -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- The general idea of the Gravitational-density Dynamo is not a perpetual motion, free-energy device. Here is the general idea of the Gravitational-density Dynamo: First, an object (the object could be a liquid) on the ground is inserted into a tall tube which contains a fluid which is more dense than the object. Also, the object should be insoluble in the fluid. Due to the density difference, the submerged object is displaced upwards. When the object reaches the top, it is removed from the tube and is dropped. Due to the force of gravity, it will fall. The energy of the falling object will somehow be harnessed to create electricity. Once the object has reached the ground, it must be reinserted back into the tube to repeat the process. (Notice that the tube should be as tall as possible so as to maximize the amount of energy of the object when it falls.) -------------------------------------------------- Here is a specific and practical version of the Gravitational-density Dynamo. This version is a perpetual motion, free-energy device. _________________________ | | | _________________ | | | | | | | | | | | | | | | | | | ------*------ <--\ | | | | | | | turbine | | | tube B --> | | (contains | | | | perfluoro- | | | | octane) | | | | | | | | <-- tube A | | | | (contains | |_________________| | water) | | | |____________|____________| /|\ \_ semi-permeable material (dialysis tubing) Tube A contains water. Tube B contains perfluorooctane. Tube A and Tube B are connected to each other by dialysis tubing, which is a semi-permeable material. Water can permeate through the dialysis tubing, but perfluorooctane can't. Due to osmotic pressure, the water in tube A will pass through the dialysis tubing entering tube B. Since perfluorooctane is insoluble in water, and since water is less dense than perfluorooctane, the water will rise to the top of tube B. Once enough water has accumulated at the top of tube B, the water will fall, turning the turbine, and returning back into tube A. Notice that this dynamo didn't require any input energy, and it will continue to work, creating electricity by turning the turbine. It is a perpetual motion, free-energy device. It is a totally renewable energy resource; it renews itself. This invention truly demonstrates that gravity creates forces which can then create/destroy energy, and that the Law of Conservation of Energy is wrong. -\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\- -|-|-| (2) CONSERVATION OF ENERGY -|-|-|-|-|-|-|-|-|-|-|-|-|-|-|- -/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/- The Law of Conservation of Energy is wrong! There are two reasons for this: 1) Attributing potential energy to objects can be wrong (esp. when the potential is due to a particular geometrical arrangement.) 2) Gravity, magnetism, etc., create forces which then create/destroy energy 1) "Potential energy" should only be called that so long as the potential cannot disappear without being realized. Consider a balloon of deuterium a meter above the ground. The deuterium has a mass of 1 kilogram and the balloon has a gravitational potential of 10 joules. Now, if we make all the deuterium undergo fusion, then we'd be left with a balloon full of helium and neutrons, and a whole lot of energy. The mass of the helium and the neutrons would be approximately 0.99999826 kilograms and the gravitational potential of the balloon (with the helium and neutrons) would be 9.9999826 joules. There's a drop in mass. And since gravitational potential energy is proportional to mass, there is also a drop in gravitational potential energy. So, where did that minute, but measurable, amount of potential energy go?!? It got turned into various forms of energy, e.g. heat, light, sound. Do these forms of energy have a gravitational potential energy? I don't think so. Some may argue that since heat and sound relate to the speed of the particles, the relativistic mass increases thus recovering the "lost" gravitational potential energy. This argument is erroneous since gravity's force depends only on rest mass, not relativistic mass. So where did that gravitational potential energy go?!? I don't know. There's definitely less. So, either we say that potential energy was destroyed without being realized (quite ridiculous), or we say that the deuterium balloon never truly had a "potential", at least not in any real sense. I'm going with the latter explanation. Thus, we can say that lifting an object in gravity does not endow the object with "potential energy". However, it does endow the object with a potential *for* energy. That distinction, "for", clarifies the entire issue. It means that should certain events occur, that potential for energy can be realized. However, it also means that there is no reality in that potential; should other events occur, the potential can disappear completely, without being realized. The potential is in our minds, on paper, in our calculations, but in reality it is nothing. A similar argument can be made for magnetism. In general, when a potential energy is a consequence of a particular geometrical arrangement, then the potential energy is most likely a potential *for* energy. 2) Energy is being created all around us. Gravity and magnetism are prime examples. Both create forces. The immediate effect of the forces on the system is nothing (the vectors of the forces cancel each other out). However, after the immediate effect, and after a minute amount of real time, the forces will be found to have either done "positive work" on the system or "negative work"; that is, energy will be added to the system, or removed. Should these forces be sustained for a longer duration of real time, then the forces might be found to have not added or removed any energy from the system (that is, it added the same amount of energy that was removed). (The portions on "(3) Bird & Earth" and "(4) Dark Energy" provide examples which relate to this paragraph.) -\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\- -|-|-| (3) BIRD & EARTH -|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|- -/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/- Consider an Earth that is stationary and is not affected by any external forces. Alone on the Earth is a hummingbird sitting in its nest in the world's last tree. The rest of the Earth is totally lifeless and motionless. Suddenly, the hummingbird, which has a mass of 5 grams, begins to hover 5 kilometers off the ground. The downward gravitational force on the hummingbird is given by the equation F = G*m_b*m_e / (r+5)² where G is the gravitational constant (6.673 * 10^(-11) Nm²/kg²) m_b is the mass of the bird (0.005 kg) m_e is the mass of the Earth (5.97 * 10^24 kg) r is the radius of the Earth (6.38 * 10^6 m) Now, this hummingbird is robust and has enough energy to hover above the ground for 10^19 years. Also, the hummingbird will at all times maintain a distance of 5 kilometers between it and the ground. As the bird flies, it is obvious that the bird is converting chemical energy into kinetic energy. As it flaps its wings, two things happen; one, air is pushed downward, and two, it is pushed upward. Since the hummingbird is a fair distance from the Earth (5km to be exact), the downward force on the air molecules never actually reach the ground because it gets distributed amongst other air particles. And so, as this force is distributed amongst billions of molecules, none of them ever gain a sufficient velocity to reach the ground, and so the force isn't conveyed to the ground. So, we took care of all the forces, right? Wrong! We only considered the gravitational force of the Earth on the bird. But what about the gravitational force of the bird on the Earth? That force creates a minute acceleration of a = G*m_b / (r+5)² = 8.196889698 * 10^(-27) meters/second² After 10^19 years, when the hummingbird returns to its nest, the Earth will be traveling at a velocity of t = 10^19 years = 3.15576 * 10^26 seconds v = a * t = 2.586741663 meters/second The Earth was stationary and now it's moving at more than two meters per second! Can you account for that? Where did the energy to move the Earth come from? Some of you may argue that the bird's chemical energy was converted into the Earth's kinetic energy. That's quite ridiculous because, as we saw earlier, the chemical energy of the bird was transferred to kinetic energy of its wings and then of air particles; in simpler terms, the bird's energy pushed air, nothing more. I hope you can now clearly see and appreciate that gravity (and other forces like magnetism) create kinetic energy instantaneously out of nothing. (Instantaneous energy is synonymous with force.) But notice that at any "instance", the instantaneous energy "cancels out". You see, as the bird was hovering, we could say that the bird was perpetually falling to the Earth. Likewise, the Earth was perpetually falling toward the hummingbird. The forces on each, bird and Earth, when taken together, cancel out. However, when the forces are sustained for a real duration of time, it effects its environment by adding or removing energy from the system. In this case, energy was added to the system; that's why the Earth is moving. What does all of this mean? It means that the Law of Conservation of Energy is wrong! It means that perpetual motion and free-energy devices do not contradict reality! -\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\- -|-|-| (4) DARK ENERGY |-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|- -/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/- Two masses (e.g. stars) with sufficient velocities can pass by each other without colliding and both gain speed. (As I say in this paper, gravity can create energy.) I believe that that might be the cause for the seeming acceleration of the expansion of the universe, not "dark energy". To illustrate, consider the following diagram; two masses A and B (indicated by asterisks "*") each with respective velocities in the direction of vA and vB. (Diagram must be read using a "fixed-size font".) * <-- mass A || \/ vA vB /\ || mass B --> * If the speed of mass A and mass B aren't great enough then, eventually, the two will collide. On the other hand, if the speeds are truly great, then the two will speed by each other without much gravitational interaction. However, if the speed is great, but not too great, then the two masses will come together, but instead of colliding they will swing around each other and exit at a greater speed than at which they entered. The whole incident, entering, "swinging around each other", and exiting, would certainly look like a dance; thus I call such a phenomenon a "gravitational dance". Since the two masses gained speed, it is obvious that I'm implying that the Law of Conservation of Energy is wrong. Yes, it's wrong. As I said, the speed of the masses must be quite great in order for a gravitational dance to succeed. Our universe is full of masses all hurtling by each other at great speeds. There is sufficient room between stars and planets so that they do not collide often; yet, that sufficient room (and great speed of masses) is ideal for gravitational dances. Thus, I hypothesize that there isn't anything like "dark energy". The fact that the expansion of the universe is accelerating may simply be a manifestation of gravitational interactions between the masses of the universe. -\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\- -|-|-| (5) WORK -|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|- -/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/- At this point I assume you have read enough of this paper to convince yourself that the Law of Conservation of Energy is wrong. Once one has realized that energy is not conserved, the big question that arises is how did something so obvious allude us, and for so long. The answer to that has many reasons. One reason is that we did not define work intuitively. I will now attempt to rectify that. Consider the following example: two classmates, Jack and Jill, both able to hold a one-kilogram brick. Naturally, holding that brick on Earth is approximately equivalent to maintaining a force of 10 Newtons. Let's say that Jack held his brick for 20 seconds, and Jill held her brick for 2 seconds. Now, without using any scientific jargon, who did the most work? Jack obviously did more work than Jill. Thus, intuitively, work should equal force multiplied by time. Notice, that this means that work done on an object does not necessarily have to create/destroy motion by increasing/decreasing velocity. On the contrary, even if you placed a book on a table, work is being done; the table is "maintaining" a force, and likewise, the book is "maintaining" a force. The force of gravity between the two is causing "stress" at the atomic level. Work, in general, does not require a change in velocity. Thus, I call "W=Ft" the equation for "general" work. Let us now consider "effective" work, a term I've coined to mean general work that increases/decreases velocity unhindered by other forces. First, let's look at it from a Newtonian point of view; let's start with "F=ma". Now, if we allow that acceleration to increase/decrease velocity (unhindered by other forces), then force multiplied by time (which is general work) becomes equivalent to "W=mv" (which is momentum). Thus, effective work is equal to momentum. Now, due to Relativity, momentum and effective work are found to be corrected to equal "ymv" where "y=1/(1-v²/c²)^½". I have found the following equation in "Introduction to the Relativity Princeple" by Gabriel Barton (pg. 189): ya = 1/m ( F - 1/c² V(V?F) ) where y is equal to "1/(1-v²/c²)^½" a is acceleration m is mass F is the vector for force V is the vector for velocity c is the speed of light let µ be the angle between force and velocity v be velocity W_g be an amount of general work W_e be an amount of effective work The above equation can be written as ya = |F|/m ( 1 - v²/c² * cos(µ) ) Since |F| = dW_g/dt (***NOTE Below) ya = dW_g/dt/m ( 1 - v²/c² * cos(µ) ) yma*dt = dW_g ( 1 - v²/c² * cos(µ) ) And since yma*dt = ym*dv = dW_e dW_e = dW_g ( 1 - v²/c² * cos(µ) ) From the above equation, we can infer two things: the effectiveness of general work decreases.. 1) ..as velocity increases 2) ..as the angle between force and velocity decreases In other words, general work is the most effective when velocity is low when compared with the speed of light, and when the angle between force and velocity nears or equals 90 degrees. As I said before, effective work is equal to momentum. And so I assert that effective work and momentum should be synonymous. And I propose that the real unit for work (that is, general work, which is force multiplied by time) should be "P", for Prescott, Joule's middle name. Thus, one prescott equals one newton second. I relegate the old, traditional meaning for work to the term "productive work". Now, work defined as it is today (productive work) is wrong intuitively, but nonetheless, it is a *VERY* *USEFUL* "measuring tool", and it *WORKS* with the non-intuitive equation "W=½mv²". It calculates "useful" work, where usefulness is defined as causing an object (I use that term very loosely) to be displaced in a certain direction. Power calculates the rate at which this "useful" work is happening. --------- Now let me clarify the vocabulary I have used here: "General work" (or just "work"): "=Ft". (calculated in prescotts) "Effective work": "=ymv" where "y=1/(1-v²/c²)^½". Effective work is general work which is allowed to create/destroy motion, unhindered by other forces. It is synonymous with momentum. Notice that the effectiveness of general work decreases as velocity increases and as the angle between force and velocity decreases. (calculated in prescotts) "Productive work": "=Fs" where "s" is displacement. (calculated in joules) Useful/Useless work: Any work can be considered useful or useless depending on the situation. You may be asking, "Why allow general work to be called "work" for short, instead of allowing that short form to indicate "effective work" or "productive work"?" I kept it that way because "general work" is a more general term compared with "effective work" and "productive work". It's kind of like how a comedian put it, "Why is it 'corn on the cob' and 'corn'? Instead, it should be 'corn' and 'corn off the cob'." Of course, one could use the short-form "work" to indicate either "general work", "effective work" or "productive work" by its use in context. --------- --------- ***NOTE: Notice that I let "F" equal "dW_g/dt" and not "W_g/t". This is because in the following steps "a*dt" is found to equal "dv". On the other hand, "a*t" does *not* equal "v", because, over a period of real time, the equation for acceleration depends on velocity and the equation for velocity depends on acceleration. The equation for velocity under an acceleration over a period of real time is more complicated than the equation for velocity under an acceleration over an infinitesmal period of time. --------- -\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\- -|-|-| (6) ELECTRICITY |-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|- -/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/- Now, I am going to apply work using prescotts on an electrical circuit. *************************** Let's find the average drift velocity: ------------------------- A is the cross-section of the wire (m²) n is "free" electrons per unit volume (electrons/m³) e is the magnitude of charge of an electron (1.602 * 10^19 C/electron) v is the average drift velocity of the electrons (m/s) I is the current in the wire (C/s) dq is an infinitesimal amount of charge (C) dt is an infinitesimal amount of time (s) dN is an infinitesimal number of electrons (electrons) ------------------------- (1) dq = e*dN dN = nAv*dt (2) dt = dN/(nAv) (1)/(2) dq/dt = e*dN/(dN/nAv) I = enAv v = I/(enA) *************************** Let's find force: ------------------------- W_j is the Work in Joules (N*m) f is the force (N) s is the distance (m) V is the voltage (N*m/C) ------------------------- W_j = F*s dW_j = F*v*dt dW_j/dt = F*v V*I = F*v V*I F = ----- v = VenA ------------------------- P is pressure (Pa) ------------------------- F V = --- enA P = -- en So we can say that "Voltage is the electromagnetic-pressure (created by an EMF source) per density of charge." Notice that the pressure supplied by an EMF has nothing to do with the length of the circuit. A battery hooked to a 1-meter circuit of 1cm² wire uses the same pressure to start a current as a similar battery hooked to a 10000-meter circuit of similar wire! *************************** ------------------------- W_i is the Initial Work (in Prescotts) (N*s) (the work done to start the electrical circuit) t is a duration of time (s) ------------------------- W_i = F*t = VenA*t Notice that in this case "W_i" does not equal "mv/(1-v²/c²)^½". This is because over the period of time "t", which is greater than the average change in time between electron collisions, the acceleration of the electron is hindered when the electron loses its energy during a collision. *************************** ------------------------- U is Initial Work (in Prescotts) per Coulomb (N*s/C) Q is an amount of charge (C) p is the resistivity of the wire (ohm*m) l is the length of the wire (m) ------------------------- U = W_i/Q = F/I = (VenA)/(V/R) = enAR = enA*(p*l/A) = enpl Now, "U" is a constant for any given circuit. So, given any circuit, a constant amount of work is done to move a Coulomb along the circuit.

Hi, I'm not a physicist, just a simple country mathematician, but I believe your statement: This argument is erroneous since gravity's force depends only on rest mass, not relativistic mass. contains an incorrect premise. Light, which has no rest mass, nevertheless bends through a measurable angle as it passes the Sun. Such a measurement performed by Sir Arthur Eddington in 1919 was an early experimental verification of for Einstein's General Theory of Relativity: [Putting relativity to the test] http://archive.ncsa.uiuc.edu/Cyberia/NumRel/EinsteinTest.html Of course by its nature "relativistic mass" depends on the frame of observation, but surely despite the flexibility this gives to different observers, it cannot be argued that gravitational force depends only on "rest mass" because light doesn't have rest mass. I guess the real test of your theory is whether you and others will be able to produce experimental verification as well. regards, mathtalk-ga |

This comment is in reply to the above comment. Light trajectory only *seems* to bend. Our space, when there is no gravity, is Euclidean; that is, the fastest way to go from point A to point B is a straight-line. However, in the presence of gravity, space-time curves. Thus, in the presense of gravity, the fastest point from A to B *seems* to have a curved trajectory. However, if you define a straight-line as the fastest way between two points, then you realize that light travels in a straight-line even in the presense of gravity; it doesn't appear straight to us because we cannot see the curvature of space-time. You're right; light does not have a rest mass. Thus, gravity does not affect light directly. Gravity distorts space-time. And a change in space-time can make the trajectory of light seem to curve. Indirect relationship.. Gravity's force depends *only* on rest mass, not relativistic mass. If I damage a car with a bat, there is an absolute amount of damage I made. We can observe that the damage may cost this much money or that much money. Nonetheless, the damage I made on the car is absolute. Perhaps it is one flat tire and a broken window. Likewise, the force of gravity between two objects is absolute. From different vantage points we may observe it to be this or that, but nonetheless, the force between two objects is absolute. Perhaps it is 5 Newtons. But, since relativistic mass depends on the frame of observation, it is obvious that gravity's force cannot depend on relativistic mass. In other words, if gravity's force depended on relativistic mass, the force of gravity between two objects would *not* be absolute. |

According to Einstein's theory of General Relativity, the "force" of gravity is not distinguishable from the corresponding "distortion" of space-time. So your point that the bending of light in a gravitational field is due to space-time "curvature" is well taken, but I cannot allow you on this account to reify some alternative "absolute" force of gravity that depends only on rest mass. regards, mathtalk-ga |

Hey, this response hould help you understand some fundamental laws of physics and clarify some of the examples you have given. I started off college as a physics major, but it was too boring, so I majored in neuroscience instead, but I still remember enough physics to respond to your ideas. 1) The seesaw motor This is pretty much how a motor works. I actually built the exact device you constructed when I was a kid. It was a wheel with magnets around it. I put four electromagnets around it, and you could hit buttons that turned them on and off, and if you did it right it made the wheel spin. In your case however, it doesn't spin in one direction, but goes back and forth, but same idea-- it just depends on your timing of the electromagets being on or off. You believe that this construction will move forward. The electromagnets M1a/b and M2a/b WOULD move forward IF they were separate from the pivot connection of m1/m2. This is because of Newton's law that everything has an equal and opposite reaction-- the M's exert a force on the m's, pushing them back. The m's exert an equal and opposite reaction, pushing the M's forward. However, this would of course only work until the M1s passed the pivot point, i.e., for the length of the pivot arm. You suggest that this is all in an enclosed box, i.e., a connected system. The forward movement, then, that you are thinking of is in the form of rotation-- the rotation of the pivot arm will exert and equal and opposite rotation of the box. The rotational momentums of the two will be equal and opposite. But the box will never move forward, it will just wiggle back and forth! 2)The simple engine You say, "If friction is used to stop the piston, the friction must cause the piston to lose velocity in decrements; should the brake make the piston stop abruptly, then the negative momentum of the piston will be transferred to the cyclinder." It does not matter how abruptly or unabruptly you slow the piston down-- it will transfer all its momentum back into the cylinder. You suggest pulling the piston back with a motor, but pulling it back with a motor will take some sort of outside energy (unless you use the energy of the piston engine, but you can't get more energy out than you put in!), but that is beside the point. The point here is that... let me explain with an example. Essentially you are saying that you shoot a gun in space. Your backwards momentum equals the forward momentum of the bullet (m1v1=m2v2). If you had that bullet attached to a cable and you pulled it back to you, your momentum will now be zero, regardless of how fast or slow you pulled it back to you. If you instead used a space shuttle or something to pull the bullet back to you, then yes, you are still moving, and you could shoot the bullet again and go back faster, but then you also have to include the momentum of the space shuttle in the calculations (because the shuttle pulling back the bullet is going to change the momentum of each), and then you cannot say that this is an independent system, or a perpetual motion machine, or anything like that. You are forgetting to include the calculations for all components of a system. In this case, momentum and energy are conserved, and the piston and cylinder by themselves will go back and forth, not forward. If you include some other system like a motor that pulls the piston back, then the momentum of that motor must be considered (and the energy needed to run that motor!). You state that the electronic analog of this could "compete with ion propulsion." Not so-- ion propulsion can exert a continuous force, but this device could only exert a force for as long as the engine is tall. Think about it. 3)The gravitational density dynamo Now you are getting somewhere. This device is as close as you get to perpetual motion. However, it too will not work indefinitely. The reason is that as water flows through the system, a few molecules of perfluorooctane will be carried in the water as a result of brownian motion and entropy. Assuming this doesn't happen is like assuming there is no friction. So eventually the perfluorooctane:water gradient will be evened out, and no more water will flow. Also, I might add, that you say that it "didn't require any input energy," but it did require energy at some point in the history of the earth to make a water:octane gradient. For example, a muscle cell uses energy to make a chemical gradient, and then uses the energy of that chemical gradient to contract. It cannot be said that it doesn't require energy to set up a gradient. But in your case, that is more beside the point. I also should add that many theoretical devices have been designed that would be perpetual motion machines were it not for friction or other fundamental behaviors of the universe. You also state that "gravity creates forces which can then create/destroy energy." Well of course that's true-- anytime you apply a force over a distance it will equal work, which is energy. This is no way shows that the law of conservation of energy is wrong. Now, on to your more theoretical discussion. CONSERVATION OF ENERGY 1) First, of all, you should realize that potential energy is the total energy that can be extracted from a system. You give the example of a deuterium balloon with m=1kg and p.e.=10J. The potential energy is the gravitational potential energy, while the mass in that equation is also a form of potential energy, as given by einstein, e=mc^2. So you can see that the gravitational p.e. was converted to pure energy. There is no flaw there, or in your words, the potential was "realized," i.e., potential energy was converted to actual energy. 2)You state that "the immediate effect of the forces on the system is nothing (the vectors of the forces cancel each other out)." I hope you are talking about equal and opposite forces, because if not, then you need to take calculus. 3) Bird and Earth example: You say that as the bird flaps its wings, the force downward is distributed to the air molecules, but never reaches the earth. Think of another fluid body (air acts as a fluid body), e.g., a box of water sitting on a scale. If you put a floating ball into that water, the weight is distributed through the water molecules, and the scale will show an increased weight, exactly equal to that of the ball. What you are saying has no basis whatsoever. So you can see that the earth would not be moving 2.58 m/s, but rather, 0 m/s, because the F of the bird downward is such that it is equal and opposite to the earth's force on it plus its force on the earth. 4) Dark Energy: Two stars approaching each other will attract gravitationally and speed up, yes, but you forgot about the gravity when the stars are moving away from each other! This will cause the stars to slow back down to their original speed. 5) Work: First, you need to realize that physics' definition of work is not the same as our daily use of the term. It does not mean effort was expended. By your definition, work is identical to momentum, which makes no sense at all. This redefines newtons law of "an object in motion tends to stay in motion" to "an object in motion must exert work to stay in motion," or "an object in motion tends to decelerate." (This, of course, is disregarding friction.) Also, by your definition, the table with the book sitting on it would do infinite work, just by sitting there forever, resisting the force of gravity! If you did infinite work, that releases an infinite amount of energy. Nonsensical. Then, you just take einstein's gamma factor and plug it into your equations with no mathematical basis, proofs, or derivations whatsoever. Also, you say the equation W=.5*mv^2 is non-intuitive-- well if you know calculus, it could not be more intuitive. I was going to comment on the rest of your paper, but since I have already disproved everything so far, maybe you should revise some things first. Well, ok, to disprove I guess I would have to go through the math of it all, but since you didn't do that either, I'm not going to take the time. Now, I don't think you're dumb by any means-- at least you are being creative and thinking about things. I'd recommend taking a 1st year physics class for physics majors. The reason is that when you take a GE physics class you learn just enough to be dangerous, ha ha, that is, you learn the concepts (which you are trying to refute), but you don't learn the math and theory behind it. Anyway, I know I could be more complete, but it's not like I'm getting paid for this, and I think what I've given you will help a lot. Cheers! |

Nice job, purkinje! I think you did a rather nice job of answering this question. Another thing to note is that it is rather simple to get around the first law of thermodynamics, which is that energy/mass is neither created or destroyed in a system, and most of your ideas can allow the energy to remain constant. However, and this is a big however, you totally violate the second law of thermodynamics, which basically states that entropy always increases. Most of your ideas assume entropy remains constant, which is unfortunately not how this world works. Furthermore, you need to take into account things like friction, electrical resistance, etc. Imagine if you will, the following device: 2 motors with the shafts welded together. The + terminal on each motor is connected to the - terminal on the other. Now, you give that motor a good ripstart, much like you would on a lawnmower. Everybody knows that a motor acts as a generator. So, (theoretically), one of your motors is generating electricity and the other is consuming electricity and generating work. Wow, there you have it -- a perpetual motion machine. Imagine bigger motors, attaching gears to it, and placing these in cars. No more pollution, you can leave them on 24-7, and you have the perfect device. Oh, except for that whole thing about friction and electrical resistance means that every cycle, you get probably only 70% efficiency, meaning after about 10 cycles, you'll have less than 3% of your original evergy in your system. Also remember that your electromagnets need to somehow be powered...if they require power from an external source, then they are not truly perpetual motion machines. Sorry to burst your bubble - you have some great thoughts, and even though some are physical impossibilities, don't stop -- keep thinking up ideas like this and keep working on it, because I'm sure when Edison introduced the idea for a "lamp that burns without oil (light bulb)", people told him that it was also a physical impossibility, or when Otto introduced the idea for the "carriage that runs without horses (automobile)", people probably ridiculed him and said it was the stupidedst idea they've ever heard. Who knows? Lots has left to be discovered in science, so don't be discouraged. |

If I'm on a bike and I stop abrubtly by pushing down hard on my brakes, I (my body) will go hurtling forth until I hit a wall. In the presence of gravity, I might hit the ground before I hit a wall, but the point remains the same. However, if I push on my brakes and slowing come to a stop, I can avoid being thrown forward. And moreover, by coming to a stop slowing, the momentum of me and the bike is dissipated as heat, and perhaps sound. That is the *main* idea of the "Simple" Newton Engine. Every action has an equal and opposite reaction. The idea is to harness the action by getting rid of the reaction. How do we get rid of the momentum of the reaction? One way is by using brakes as said above. The idea is to get rid of the momentum of the reaction by dissipating it as heat and sound, and thus letting the action propel the device forward. Do you understand it now? --- --- You're right.

Here it is: "Gravitational potential energy is energy an object possesses because of its position in a gravitational field." (I got that from http://hyperphysics.phy-astr.gsu.edu/hbase/gpot.html) For the law of conservation of energy to be correct, the amount of potential energy, kinetic energy, and the energy from mass from *before* and *after* must be equal. ( letting g, the gravity, equal 9.8 J/(kg*m) ) Before: Energy from mass of balloon full of deutrium: 1 kg which equals... E = mc^2 = (1 kg) * c^2 = c^2 Joules Gravitational potential energy of balloon full of deutrium: 1 kg, 1 meter above ground... E = mgh = (1 kg) * (9.8 J/(kg*m)) * (1 m) = 9.8 Joules Between before and after, the balloon full of deutrium undergoes fusion, leaving behind helium, neutrons, and a whole lot of energy. I realize that I haven't taken into account the initial amount of energy to initiate the fusion. Nonetheless, the equation I use, which is stated below, is balanced: deutrium atom + deutrium atom => helium atom + neutron + 3.27 MeV (found the above equation at http://hyperphysics.phy-astr.gsu.edu/hbase/hframe.html) After: Energy from mass of balloon full of helium and neutrons: 0.99999826 kg which equals...

E = mgh = (0.99999826 kg) * (9.8 J/(kg*m)) * (1 m) = 9.799982948 Joules Adding up the before and after, we find that..

I feel obligated to clear up your remaining questions, mostly for your own sake, so that if you get into a conversation with a physicist you will not sound completely uneducated. First, I did understand the seesaw motor. Read my response more carefully-- the reason that the box will just "wiggle back and forth" is because the rotating arm is wiggling back and forth. The system will rotate back and forth with an equal and opposite momentum as that of the rotating arm. Second, again, it does not matter how abruptly or unabruptly you slow the piston down-- it will transfer all its momentum back into the cylinder. You give the example of braking a bik-- regardless of if you slam on the brakes or apply them slowly, by the time you are stopped, all of the momentum will have been transferred to the earth (not to yourself, as you describe-- you are on the bike!). Since the earth is so much more massive than you, you don?t even notice its change in velocity. I know what gravitational potential energy is. You are saying there is some sort of "conservation of gravitational potential energy"-- i.e., all gravitational potential energy must be conserved. There is no such law! It is only the conservation of total energy! Just because gravitational potential energy is converted to kinetic energy when something falls towards the earth doesn't mean there?s any violation of law (as I'm sure you understand), and neither does mass being converted into energy (as happens in your example) violate any law of the conservation of energy. Yes, of course energy is going to be released (but not created!) if two bodies (e.g., stars) approach each other and speed up. It is just potential energy being converted to kinetic energy?- just like an apple falling towards earth, its potential energy is converted to kinetic energy, seen as velocity (and yes, the earth also accelerates towards the apple, ever so slightly). If the star collides with something after speeding up, that's just like the apple colliding with the earth?s crust, or something like that. All well known principles. You can't just answer my points with, "well, that?s not EFFECTIVE work" or something like that. What is the mathematical difference between effective work and 'non-effective work' in your theories? If there's no mathematical difference, then there's no difference at all. Ok, so if an object is just moving along through space with no forces acting on it, it has a momentum. You say that that is the same as work, i.e., the object is doing work. You are saying the object is doing work to stay in motion, then it must decelerate, because it has to give off energy to do work to stay in motion. Or maybe you are saying that the object is giving off work as it moves through space, so it should be accelerating. Either way, Newton showed how an object in motion will stay in motion without exerting any effects on its environment and with no external forces acting on it. I think what you are trying to get at here is that the moving object has energy which can be harnessed to do work, i.e., the kinetic energy can be made to exert a certain force over a certain distance, thus doing work. Or a book sitting on a table can be harnessed in a gravitational field to do work. But the table just sitting there resisting a force is not doing work. Work is a force applied for a distance through space. If nothing is moved through space, then there was no work, although there may have been energy needed to create the forces themselves. I admit that the connection between our daily use of the term ?work? and the physics use of the term is somewhat confusing. I?m sure there are many good examples of why it is defined that way, but I?ll leave that up to you to figure out. Just take a good, rigorous physics class, and it will help a lot. |

The problem with your views is that you are only considering two types of energy: kinetic and gravitational potential. However there are many many other forms of energy out there such as stored potential (like a spring), chemical (like the energy release when you combust gasoline), atomic (from atomic vibrations) and so on and so forth. If you sum up ALL the energy in a closed system, it will always always always remain constant. You can convert one form to another as much as you want, but you can never create energy; you can never destroy energy. Also, note that WORK by definition, can be positive or negative, and is a VECTOR relationship, not scalar. For instance, if you lift a one newton block one meter against gravity, you have performed one joule of work. By bringing it back down, you effectively perform negative one joule of work, for a total of zero work. That's the problem with your seesaw - it just piddles back and forth; does NO work...it's not that it is ineffective work, it's that it sums up to NO work. |

Hi blochee, There are lots of areas where you could but your enthusiasm and brainpower to good use. Lots of areas of science are still developing, and lots of work needs to be done. This is not the case with classical mechanics, or electromagnetism. If you're interested in doing scientific research, you could consider getting into one of the younger fields, say environmental science. If physics is what you're into, you could do that too, but first you have to learn the basics--one of which is that conservation of energy is NOT wrong, at least not on a macroscopic scale. If you would like to make a contribution in the physics field, you are shooting yourself in the foot by convincing yourself that centuries worth of carefully tested theory is incorrect.

Further to the other comments on this paper, there is a more fundamental flaw in invention three: The Gravitational-density dynamo. If we were to view the system as a simple tube of water and a tennis ball. To start the process off we insert the tennis ball into the bottom of the tube. This of course would have to be done in such a way as to let none of the water out but let's assume for the moment that we can do that. Once the ball is in the tube it will float to the top. However... When we put the ball into the tube we have to displace the same volume of water. It can't come out of our trap door (we made it one-way only) so the only way for it to go is upwards. In short, the entire column of water is lifted up by the same volume as the tennis ball (other wise there would never be room for it). It's this increase in the water's potential energy which provides the force that lifts the ball upwards - and it's precisely the same amount of energy as you gain when the ball falls again. In your example, this is all tucked away in that osmotic membrane. Such membrane's use energy and in this case the amount of energy necessary to push the water into the column of perfluorooctane (and consequently displace the molecules of perfluorooctane upwards) is the same as you would gain from the turbine in the first place. Take into account the rest of the losses (friction etc.) and you very slightly lose energy over the whole cycle. Regarding the apparent loss of energy in the deuterium example, your claim that the force of gravity depends only on non-rel mass cannot be substantiated. The idea that the displacement of light due to curved space-time is somehow fundamentally different from the application of a gravitational force is absurd. There are two (equally valid) ways of viewing it... Either gravity is a force that affects all objects (light included) OR gravity is a space-time distortion and all objects move across that distortion via a geodesic (shortest) path. You can't say it's one view for some objects and one view for the others. Either way, the total potential for the system doesn't change. It's just that the photons are now carrying that potential as they have a mass (relativistic) and are in a gravitational field. Some interesting ideas though. It takes a while to figure out where the problems lie. Hope that helps. LJ. |
