1. ### Idea of increased mass at relativistic speeds

Even if a particle is neither moving nor part of a bound system, it has an associated energy, simply because of its mass. This is called the particle's rest energy, and it is related to the particle's rest mass as rest energy = (rest mass)· c2 This in Einstein theory. E=Mc^2 has many...
2. ### Square speed of light!

I don't have only a problem, I have several problems. Lets see why the Gravitational constant it's not sacred. That's why there are another methods to mesure gravity. It is readily apparent that the current gravitational constant is not a tangible physical concept as demonstrated by its...
3. ### Square speed of light!

That means that you don't agree with my affirmation? This is a common knowledge between mathematicians; it is similar to fundamental research (or basic research) and applied research. If you read all my posts you will understand that they are different from the first. I inserted lots of...
4. ### Square speed of light!

It seems that anything multiplied by mass in Einstein formula will have a physical meaning, probably even potatoes :)
5. ### Square speed of light!

Did you understand that I was talking about the nuclear bombs?
6. ### Square speed of light!

r^2 is geometrically explainable, but c^2 with it's extraordinary units it's not so easy to explain.
7. ### Square speed of light!

About my posture you are wrong. I am always searching for something to learn. My principle is: we can learn so much with the ones that don't know nothing. I knew that m.m/s.s is equivalent to m^2/s^2, this is basic! But even if I had written correctly my doubt about velocity will be...
8. ### Square speed of light!

That happened at my first thread. But why are you fixing your focus on that, taking in consideration that you can see in all my threads from that point that my positions didn't have nothing to do with the difference between m/s and m^2/s^2? After all, until now, no one explain the meaning of...

Thank you for you exposition. But where do you get the idea that I considered that c is equal to c^2? The problem is that 89875517873681764 m^2/s^2 have to be verified in a concrete experience. I don't know any experience where this have been verified. It is always said that the formula...

11. ### Square speed of light!

The scope that underlies my participation in this forum, is mainly related with the difficulty in define the exact characterization of c^2 and it's qualitative meaning, on the other hand, the inexistence of an empirical demonstration where the Einstein formula has been completely proven...

The specific physical transformation results from the other forms of energy. The main energy set free in a nuclear fission results from binding energy converted to other forms of energy.
13. ### Square speed of light!

Generically speaking the difference between pure mathematics and applied mathematics. I know that there are several cases where pure mathematics became applied mathematics. But I am not so optimistic as Nikolai Lobachevsky: "There is no branch of mathematics, however abstract, which may not...
14. ### Square speed of light!

Einstein would say that in a system where there is energy (E), it automatically has the relativistic mass m=E/c2; whenever a system has the mass m, you need to assign it an energy E=mc2. Once the mass is known, so is the energy, and vice versa. In that context, it makes no sense to talk about...
15. ### Square speed of light!

The mathematic meaning could be far from the pratical world. Don't you know many situations in which this happens? Mathematics couldn't be seen as an absolute concept to explain the world, notwithstanding the enormous help that gave and will give in our understanding of the world .
