Mostly stuff about astronomy, physics, and math

Two mini book reviews on comets, asteroids, and astrophysics

I’ve been reading a lot more books than usual this year, for some reason. I don’t read a lot, so it has been nice to get back into reading more books.

Catching Stardust: Comets, Asteroids and the Birth of the Solar System was really good. I really liked chapter 8 on the Rosetta mission to Comet 67P/Churyumov–Gerasimenko. I find it fascinating how the little Philae lander bounced around the comet before coming to rest in a low section. It was still able to do good and unique science on the way there.

Astrophysics for People in a Hurry was written by Neil deGrasse Tyson back in 2017. I had been meaning to read it for a while, and it was a good quick read. My favorite chapter was the last one on the Cosmic Perspective. I liked this line:

The cosmic perspective opens our eyes to the universe, not as a benevolent cradle designed to nurture life but as a cold, lonely, hazardous place, forcing us to reassess the value of all humans to one another. (Page 206.)

I added some photos to the Flickr best and worst photos of 2020 contest

Can you guess which ones are mine?

History of the Science Library Domain

From 2001 till at least December 22, 2009, I had the sciencelibrary.org domain set up in my personal space at the University of Denver as a URL redirect to:

http://mysite.du.edu/~jokraus/scilib/index.html

Because of the way that DU redid personal website links (around 2006 or 2007), the internal links no longer work, so these are the internal pages at:

I also saved the content to the Archive at various times.

Then in 2009, I learned that I could have Tumblr host it as a blog, and I could have the URL sciencelibrary.org redirect there instead of redirecting to my personal webspace at the U of Denver. But, Tumblr has a less than stellar reputation in the blogging world.

So, in November 2020, I moved ownership of the domain from Network Solutions to Reclaim Hosting. This is where you see the website now. I hope I can keep it here for more than another 10+ years.

Where the old content is

I used to have a Tumblr blog that would redirect to this URL, and that old stuff can be found at sciencelibrary.tumblr.com. For many reasons, I moved it from tumblr to my own hosted site using WordPress software.
