When the space program was started back in the beginning of the 1960’s how to guide the spacecraft in space was a complete unknown. The problem of calculating burns and orbital insertions was a nontrivial one. At the time all flight control had been analog and in 1960, the computers filled up buildings. When the call came to go to the moon, one thing was clear though. A computer small enough to fit on the spacecraft was going to be essential. That computer would be the Apollo Guidance Computer(AGC).
I don’t have Netflix or even a TV, so I haven’t seen Stranger Things other than some ads on You Tube. This post turned up and I thought that I would share my experiences working at a DOE National lab. The author of the post is a little retrained so I thought that I would liven things up.
Thunderf00t has released another video on the Hyperloop.
In it he takes the fans of Elon Musk to task and references the Hyperloop Alpha Document. I took a look at it and from a professional’s standpoint, it’s a very interesting diagram, but not in a good way.
Now I’m somewhat of an expert in all the technologies and I’m sorry, but I see some issues. First of all the booster vids.
Here’s an interesting piece from Time magazine:
The funny thing is that getting fusion isn’t really that hard. The Farnsworth Fusor which almost guarantees that you get some fusion neutrons isn’t that hard to fabricate.
Kids as young as 13 have built fusors and frankly I think that they are a good way to learn about vacuum, useful even if you don’t get useful energy out of your gadget. And they are cool.
I’ve posted before about fusion energy before. Especially about Robert Bussard’s polywell. Not perhaps as much as I should have. Especially about the polywell. I became interested in the polywell when I watched this talk from Robert Bussard back in 2007.
Recently Sarah Hoyt published a post of mine:
While I was ecstatic to guest post on Sarah’s blog, File 770 reposted with their usual editorial style and Mike’s commenters behaved in their usually classy, hyper intelligent fashion, flinging their usual monkey poo. Because they didn’t actually read the links I posted they really had no way of knowing what I was talking about. I was directly referencing and being critical of the post that Mr. Robinson wrote, not the novel. But if you didn’t read the posts there’s no way to understand that. Thus the monkey poo. That’s what happens when you don’t understand things.
Apparently when I tried to point out that I was using a professional perspective I was being pompous.
