he discovered the speed of light
This is because nothing else in the entire discovered universe moves as fast as the speed of light!
Einstein
"Speed" & "Velocity" are the same thing, they were not "invented" but discovered so to speak through Theoretical physics.
Olaus Roemer discovered the speed light in 1676.
it was MAxwell the dude who discovered electromagnetic waves
A German physicist. He discovered a method for working out the speed of sound in different gases.
probably all kinds of technology
... its speed is the same in any direction, even if you're movingin that direction or in the direction opposite to it.
The second species in any environment.It was either a predator and wanted to move faster than the first to catch and eat it, or it was the prey and wanted to get away! So several millions of years before the first humanoid.
No!...Speed of light is the fastest speed possible, but now a new particle called lepton is more faster than light...rather it is has the fastest speed discovered till now.It travels in the same wave as light travels i.e tranverse waves.
The jet stream was discovered in the 1940s during World War II by Japanese meteorologists studying air currents. They noticed a strong, high-speed current flowing in the upper atmosphere.
