OK, so while I was in college studying aviation, we did touch on Atomic energy. a nuclear bomb and an Atomic bomb are ‘basically’ one in the same. The difference in the the two bombs is how the atoms are split . One by fusion and one by fission. For me to go any deeper, I would need to fill a page of worthless information that almost no one would care to read. However, if you want to dig into it, I am sure that there is plenty of information on the web.
When I worked for United, my home airport was Washington. From time to time, I would stay in D.C. just as a matter of convenience. To pass the time, I would visit the Smithsonian. This place is huge. There is a Nuclear and Science section in one part of the Institute. I don’t know where you live, but if you really want to explore more about Nuclear Fusion and Fission, that’s the place to start.
In college, I took a double major in engineering; Design Engineering and Aviation Engineering. My first consideration after college was to be an Aerospace Engineer and work for NASA as a Propulsion Engineer, but I learned soon enough that I just wasn’t as smart as I thought I was. When it came to remembering formulas to come up with the needed amounts of propulsion to lift off rockets with boosters to get the shuttle or whatever vehicle is attached into space, Man, I was lost in space myself. I ended up working for DuPont.
