Tha Law of theoretical velocity

[Zorgon]

A strictly logical argument to invalidate E=mcsquare, E=mvsquare and other formulas using the illogical multiplier efffect (squaring) and to replace them with a strictly logical formula producing the same results.

The cited essay includes this passage: "...the energy invested in overcoming inertia is retained as the kinetic energy or momentum of any moving body".

I think it is a flaw to put the connector "or" between kinetic energy and momentum, since it has been found that these two are entirely different, and each is independently conserved. Perhaps that's where the author erred.

Aside from that, I don't think the author understands Relativity correctly. I cannot believe that anyone would, at this late date, question the formulas for kinetic energy and in the same breath claim that differently moving observers reckon different speeds (by a factor of 20 or more!!!) for the same light beam. ALL of that stuff is extremely well established and tested and employed successfully every single day; by NASA, by The Pentagon, by FermiLab and so forth. I can't believe this guy's audacity (or more likely, stupidity).

I was curious about this as well. It is like this post(s) by Zorgon came from period of the past before
Einstein ever existed. Hmmm. I wonder.

Aw, face it. Its just plain FUN to claim that Newton, Galileo, Einstiein, et al are a bunch of idiots and only YOU are enlightened enough to understand the meaning of life, the universe and everything! See that silly thread about "The Final Theory" over in Books/Games/Movies....

Only true intellects like Newton have the modesty to admit that they stand on the shoulders of giants....

I guess I never thought of it that way. I did go look up the thread you mentioned. I will
look for the book as I am curious. I did mention a book, "God's Debris", by Scott Adams,
that I think wraps it all up with a nice valentine bow on it.

I don't mean to be mean but This guy needs to read more science and the reconizes differences. The E=mc² equation does not pertain to Kinetic energy only to the total rest energy of the mass. The Kinetic energy Equation is
K = 1/2mv²
or for relativistic effects (or added accuracy)
K = γmc² - mc²
and the sum of energy equation is:
E = K + U

I forget the Potential energy, U, equation sorry but there it is. Also for future reference.
t' = γ(t - vx/c²)
γ(small gamma) = 1/(√1-v²/c²)
This is the basis of Time Dialation. The idea that time "slows" as one approaches the speed of light. This is mearly a missinterpertation. Time does not accualy slow but rather distances shrink. it is not only the object moving near c that shrinks along the x-axis but the distance in which it is moving in.

From this distance shrinking it is a shorter trip and therefore less time. This allows the Theory of Relativity to explain why relative to the observer moving at these speeds he precieves time as "normal".

More on this over at the best classical physics refernce I've found:

Even has some stuff on QT and QM.

While I agree with your main critique of that "Law of Theoretical Velocity" essay, you have made a very bad misstatement in the passage above. It is you who has made the misinterpretation if you think that SR distortions can be explained by length contraction without time dilation. In fact, time dilation is every bit as crucial as length contraction and they go hand-in-hand... along with a third distortion that can be loosely termed "clock dissynchronicity". The computations of SR work out correctly only when applying all three of those!

P.S. Can you spot the three spelling corrections I made in your quoted passage?

[KickAssClown]

If I was writing this for a book review or otherwise to go into print I would care about my spelling otherwise I could give a care less. You understood more or less what I had to say.

As for Time Dilation it is length contraction. All the equations of lorentz and SR and GR are interelated. Just realize all is Relative. What I see is as equally right as what you see. in anycase.

If i'm traveling at 60mph 120 miles it will take me 2 hours to get there. If I'm traveling at 60mph 60miles then it would take me 1 hour to get to my destination.

See if time did slow down then it wouldn't work out quiet right. The twin paradox is based on length contraction. I mean I understand t' and all but it's based in distance.

Length contraction is just a result of the measuring sticks used in a different time frame will NOT contract. The contraction appears in the direction of motion and is only apparent to an observer in another frame.

I fail to see how the preceived length contraction of a spaceship, say, actually shortens the distance the ship has to travel.

The example you give about (60mph) is not valid because length contraction happens at relativistic speeds.
