I am an engineering professor. I still love learning new things. I recently chanced by a series of youtube videos by minutephysics and was completely in awe of the simplicity and brilliance of his teaching. Here are some examples of amazing little videos Henry Reich produces.
I know it is a very popular channel, but never saw anybody here talk about them.
First my favorite ones
Open Letter to the universe
What if earth were hollow
What is Fire?
Why is the sky dark at night?
These are only a few of the brilliant videos he makes.
Here is him explaining his process
And finally the latest video.
An open letter to the president of the USA.
I know this is not much of a diary... But just wanted to share. Also check out vihart's Hexaflexagon series
