Vsauce: How Many Things Are There?May 5th, 2014
Vsauce takes a fascinating look at how many things there are in the universe, from the number of humans to the number of LEGO bricks ever manufactured. But how many “things” are there in total? And by “things” he includes anything you can think about or talk about including grains of sand, imaginary things, ideas, impossible things, things in the past, and on and on.
How does one go about estimating the total number of such things in the universe? Well Vsauce gives it a shot and the process behind it is fascinating.
