I did a quick search on "Einstein's Big Idea" with too many results.
Added in "NOVA" and came up dry.

Is there a discussion here on the show?

We watched last night. WOW!

Suprising stuff about the guy that "discovered" electromagnetic radiation.
I didn't know he was laughed at when he first theorized it.

It was also the first time I can recall actually hearing E's attempt to visualize looking in a mirror while traveling at or near the speed of light.
How he had his epiphany while viewing clock towers at varying distances from a hilltop.
Now this idea, that the perceived speed of light won't change for an observer traveling at or near the speed of light due to time dilation has really sparked soemthing in me... having trouble visualizing, formulating how this "relativity" might translate into other areas.

Like...
A seemingly simple question like, 'How much do you weigh?' in today's day and age, where few people would have any other experience of weight besides the weight they are on this 3rd rock from Sol, would require clarifiers, in say - 500 years, when/if humanity colonizes planets of varying mass.

Weight is relative...
Time is relative...
Distance is relative...
space is relative...
speed is relative...
age is relative since time is relative...
mass is relative since space is relative?
