Janus' method for non-linear velocity addition]]>

By observing electrons that have been accelerated to extremely high energies, scientists are able to unlock clues about the particles that make up our universe.

Accelerating electrons to such high energies in a laboratory setting, however, is challenging: typically, the more energetic the electrons, the bigger the particle accelerator. For instance, to...

New laser technique: More powerful—and smaller—particle accelerators]]>

But why (use complex frequencies)? When I studied electronics this wasn't really explained, we just did it.

That is, what motivation is there, as they say? How to justify this choice of an imaginary sine wave term or sum of terms?]]>

1. Measure the tested object's length at rest, the value l0.

2. Put this object in motion.

3. Measure the object's speed, the value v.

4....

How to test length contraction by experiment?]]>

Is it as difficult as Finite Element Method?]]>

So, is there anything in the universe will remain at rest forever?

It seems NO.

Because everything is moving.

Any object in outer space remain static?

So, how could Newton's first law is valid?]]>

Given "u" the velocity of A relative to the earth, "w" the velocity of spaceship B relative to A, you should find "v" the velocity of B relative to the earth.

------->velocity positive direction

Earth ……………………………….A…………………………………….B

……………………………………....u...…………………........…......…..v

u is the velocity of A relative to the Earth

v is the velocity of B relative to the Earth

x is the velocity of Earth relative to B

w is the velocity of B relative to the A...

What do you think about this? Opinions welcomed...]]>

Does space exist first or time first?

Or they must exist together at the same time?]]>

NASA mathematician Katherine Johnson did more than just calculate rocket trajectories for early space missions. Her story, when it was finally told, completely changed people’s perceptions about who has been – and who can be — important in history....

Another observer watches from a station as the train goes by and because of the movement of the train and distance the light has to travel, sees gunman A fire first. That gunman's bullet travels...
