Article Constant Speed Einsteins crucial breakthrough in 1905 can be summed up in a deceptively simple statement. Richard Feynman discusses how Newton was able to explain gravity the tides and how we first calculated the speed of light. Its the worlds most famous equation but what does it really mean.
The speed of an object v is related to p and E by the boxed equation.
C ϵ 0 m 0 1 2. You wont go broke betting on Einsteins ideas to hold up. It can be derived from Maxwells equations that the speed at which electromagnetic waves travel is. Einstein argued that space and time were relative and that the speed of light was the constant that connected the two.
