Well, I'm glad to see that you replaced E=mc^2 with E=mc^2/(1-v^2/
c^2). At least now you're not talking about rest energy.

And it's pretty obvious that E=mc^2/(1-v^2/c^2) goes to infinity when
v approaches c. The term in the denominator becomes zero, and you know
what happens when you divide by zero.

On the other hand, I wouldn't dream of saying that E=(1/2)mv^2 goes to
infinity when v approaches c. Any child with a 5th grade math
education will see that it doesn't. I assume you've at least had a 5th
grade math education.

Of course, E=(1/2)mv^2 is known to be an approximation that only works
when v is much smaller than c, and can't be used reliably at all with
v anywhere near c.

However, the fact that energy goes to infinity when v approaches c
doesn't violate energy conservation at all. It is true, just as it has
always been true, that any energy increase is due to work done by an
exerted force, and this is what energy conservation requires.

It is also true that for any v at all less than c, the energy is not
infinite. Big is not infinite. And as we calculated before, the energy
required to get a proton up to 0.9999995 c is actually pretty small,
about comparable to dropping a nickel from your pants pocket.
Moreover, particles that actually do travel at c do so without
accelerating them from any lower speed, and so no big amount of energy
is required to do that either.

They do not, and shed Rœntgen and Chèrèncov heat along the way.

realizing that fact! Pardon me for not copying that God d. Lorentz

energy." In no way is the velocity of the velocity of light part of
the measure of the total energy within a given mass. Einstein was
also totally clueless as to just what kinds of energy will convert to
mass. Unfortunately for Einstein, VELOCITY can never be converted to
mass!

When I say "exponential" I mean at a rate of increase greater than
linear. "Quadratic" applies specifically to parabolic rates of
increase, like d = t^2. I am well aware that Coriolis's equation, KE
= 1/2mv^2 doesn't have the KE going to infinity at velocity 'c'. What
I was wanting you to grasp is that both equations increase
exponentially (non-linearly). Thus, both equations violate the Law of
the Conservation of Energy. That's because the two equations "input"
velocity uniformly, but "output" the E or KE exponentially (non-
linearly). Effectively, both Coriolis and Einstein created energy in
their own minds that was never being imparted by Nature!

Coriolis's equation was semi-quadratic, not quadratic. I suspect
Einstein dropped the... "1/2" so that people wouldn't realize that he
had copied Coriolis. Einstein had no idea whatsoever how much energy
resides inside of a given mass. He would leave that up to future
generations of scientists to figure out.

I hope you feel better for beginning to side with science truths, not
just the errant science status quo. The problem for both of us, now,
is that those in academia couldn't care less about science truths so
long as they can keep repeating their boring memorized lessons, and
keep getting NSF grant money to research anything and everything
about... Einstein's notions. The desire of young minds to
'understand' relativity has been a cash cow for universities. If I
had the power, I would fire 75% of the physics teachers at
universities and increase the entry requirement so as to reduce the
number of ALL students by 50%. There is far too much emphasis being

Well, "SR" doesn't go to infinity. There is a Lorentz factor gamma
that WOULD go to infinity at c. However, no massive particle ever gets
to c, so no massive particle ever sees a Lorentz factor gamma of
infinity, and the Lorentz factor gamma does not apply to massless
particles.

And this shows the problem with trying to understand relativity by
reading encyclopedia articles.
It may be of value to you to learn read something of more depth and
quality if you want to really understand it better.

Well, you may want to consider how two particles as light as electrons
can collide at high velocities and produce a particle that is 90,000
times heavier than the two electrons combined. And yes, this has been
done millions of times.

Then this is a terminology problem, because that is definitely not
what "exponential" means to mathematicians and scientists. This is
part of the thing that I've been reminding you of -- that certain
words have very specific meanings and you've been using them in a much
looser and inaccurate way.

ANY function that goes as the square of another quantity is a
quadratic function.
So, for example, (1/2)mv^2 is quadratic in v.

Quadratic is not exponential. Neither of them is linear, but that
doesn't make (1/2)mv^2 exponential. I'm asking you to learn how to use
terms appropriately.

That's what ANY quadratic function does. For example, in d=(1/2)at^2,
you input time uniformly and the output distance emerges non-linearly.
That isn't a violation of anything.

Nonsense. All the energy is delivered by work, which comes from force
applied through a distance. There is no energy that comes from no
place. It's all accounted for.

"Semi-quadratic" is a meaningless word.
The area of a circle is quadratic in the diameter: A = (1/4)*pi*d^2.
The presence of the constants out in front doesn't change that fact.

A function can be linear in one variable and quadratic in another.
For example, d=(1/2)a*t^2 is linear in acceleration a, and quadratic
in the time t.

All this is 6th grade arithmetic, John. Perhaps you have forgotten
your 6th grade arithmetic.

Please, John, stop making stuff up. It's transparent, and it makes you
look bad.

You owe your livelihood to your college degree, John. You would not be
able to work at your profession without it.
