Hey CD
These are not test videos. They are very interesting videos of a stick man using animation to explain mathematics terms and concepts in an entertaining way. It explains things like the the Golden Ratio and the Fibonacci sequence and even Mobius strip and other higher mathematical concepts in an entertaining way. It introduces these concepts in ways everyone can comprehend. The first video is only 9 minutes. You should watch it.
I appreciate you sharing the NPR new quiz show. I too respond to comedy in everyday situations. To me comedy is an excellent way of coping with the "opportunities" or bad news and bad situations life throws at us. I adhere to "a spoon full of sugar helps the medicine go down."
I used to watch and old tv show called "In Living Color". The creator of the show said that to create comedy he would "find the funny" in situations.
That is how I view politics and national news. I try to find the funny. You know yourself in the good ole US of A.. we have quite a bit of funny in every election, in every tax raise and have mercy some of the silly laws that our legislatures pass are unbelievable. I make it a point to not talk about politics in public so you would never know which side of the isle I am on but I love to listen to comedians make fun of both sides. Gotta be fair and zing everybody.. LOL
