And the 20% enrichment line separating low-enriched uranium from highly enriched uranium is also a bit arbitrary. The official reason is that below 20% a runaway criticality(atom bomb go boom!)was impossible. Thispaperexplains how that really ain't true. You can have a runaway criticality ...
Aspect Map by Daniel Swensen click for larger image Now remember that I said Microscope was used to make the background history, while Diaspora was for the map. The above image is a Diaspora Cluster map. A, B, C, D, E, and F are solar systems, places the players can visit. They ...
This design was adapted as a manned upper stage for the A-9/A-10 intercontinental missile, which would glide from a point over the Atlantic with just enough range to bomb New York before the pilot bailed out. Post-war development In the immediate post-war era, Soviet rocket engineer ...
"Inside the system, we had a map of the area we were in, and we were able to plot points on the map. And then you could take the map away, and you would have arrows and a compass where you could walk to those points. And it would be something almost out of a video game just...
Preferably the Time Bomb. Two other pieces were the Magician and the Troll. The Magician moved like a Bishop, but couldn't capture. It moved into position so that another piece was attacking it. If a piece attacked the Magician, even inadvertently, it died. The Troll was the only piec...
The Manhattan Project bomb-builders’ concern about an A-bomb-derived atmospheric conflagration has contemporary analogues. There have been speculations that future high-energy particle accelerator experiments may cause a breakdown of a metastable vacuum state that our part of the cosmos might be in, ...
In this later map, I designated an empire's homeworld if it was the closest Sol type star to the geometric empire center The white dotted lines connect stars that composed the "neutral zone" between empires. These are stars that are ±20% of being equidistance from the nearest two empire ...
(In THE REVOLT ON VENUS, this is what Roger Manning was looking through when he noticed the atomic bomb attached to the Polaris' tail) There also might be a goniometer, which is used to measure angles. A good-sized telescope, either in a dome or with a coleostat. (The periscope, ...
