How can species develop from simple life to more complex life and become more ordered in the process?]]>

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.

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...

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?]]>

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...

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....
