A quick note on Useful and Useless Things

I have started a new video playlist about things I find useful. If you are so inclined, I hope you'll give it a watch from time to time. Here's the first one.

Homework from Professor Shostak

Seth Shostak may be right about UFOs,or he could be wildly wrong, but it is difficult to ignore his critiques of the the notion that UFOs are spacecraft from other planets. The SETI astronomer and podcast host recently appeared on Martin Willis' Podcast UFO to explain his views, which are also laid out in Chapter 4 of his book, Confessions of an Alien Hunter.
