It’s been a few minutes since the last Wednesday Wow post, and I’ve got two recent videos that definitely made me go “Wow!”
I have a third that is cute and interesting as well as a fourth that’s kind of math-y but lighthearted and certainly relevant (and which will introduce you to Benford’s Law if you haven’t heard of it).
The first video involves a tragic disaster that occurred on the first of this month down in Puerto Rico when the Arecibo radio astronomy telescope collapsed.
This is the key to understanding the Lorentz Transformation.
With COVID-19 putting a damper on social activity, “the gang” doesn’t get together very often, but we still gather occasionally (and carefully). One of the times recently I got into how, even though we’re all sitting essentially motionless in a living room, we’re moving through time at the speed of light. I explained why that was, and they found it pretty cool.
Then I ran into someone online who just couldn’t wrap his head around it — just couldn’t accept it (despite explaining in detail and even providing links to some videos). Physics is sometimes challenging to our daily perceptions of reality!
In this case, though, it’s just a matter of some rather simple geometry.
