Mr. Trump, Please Get Some Sleep


Sleep is essential for good mental and physical health. It helps us heal when we need healing. I went to bed very early last night, and got all the sleep I need to do well at work today. I wish to suggest to our president that he do the same.

At least eight hours of sleep a night is healthy and helpful. Also, especially for a man in his seventies who is under a great deal of stress, long naps during the day can be a literal life-saver. In Mr. Trump’s case, the number of lives saved can be very large indeed.

To free up time for sleep, I have one more piece of advice for the president: limit yourself to one tweet per day.

A Tessellation Using Regular Pentagons and Hexagons, As Well As Two Types of Concave Polygon


Without even checking, I know that my automatic tweet about this post (as @RobertLovesPi) will be retweeted by the @HexagonBot on Twitter. Why? Because @HexagonBot retweets any tweet containing the word “hexagon,” or “hexagons.” I have absolutely no idea why other polygons lack their own Twitterbots, though.

Sixty Flying Hexagons

When I tweet a link to this blog-post as @robertlovespi, it will likely be quickly retweeted by @hexagonbot, simply because of the term “hexagon” being included in the tweet. What I don’t understand: Why do other polygons not have bots of their own?
