Friday Facts is back!

After this week, when North Korea decided to do what they did, what else could be the theme for Friday facts than the hydrogen bomb?

1. the hydrogen bomb is also called the H-bomb, a fusion weapon/bomb, or a thermonuclear weapon
2. the point of a "real" hydrogen bomb is to get hydrogen to fuse, and to get a large portion of energy released from this reaction
3. to get the hydrogen to fuse you have to make it hot enough (you try to recreate what happens in the sun) so that light nuclei will fuse and release even more energy than in a "normal" atomic bomb/nuclear weapon - the word thermonuclear means that the fusion takes place when the temperature is extremely high
4. a hydrogen bomb is also an atomic bomb/nuclear weapon, but it was developed some years after the fission bombs ("normal" atomic bombs) that were used in 1945, on Hiroshima and Nagasaki - the only time nuclear weapons have been used (a hydrogen bomb has never been used - only tested)
5. the first step of a hydrogen bomb is a fission bomb, which makes the temperature so extreme that fusion may start
6. I don't understand this mushroom cloud from the North Korean bomb test on Wednesday, since they did it under ground... I think they've either had fun with photo shop, or they just "borrowed" the pictures of the cloud from somewhere else (maybe Kim Jong Un really loves mushroom clouds?)
7. in addition to a real fusion bomb (where most of the energy released comes from fusion reactions), you could make a fission bomb that is boosted with hydrogen - this means that there will be some hydrogen in the weapon that fuses, and from these fusion reactions you get more neutrons so that even more of the fissile material will fission. Almost of all the energy released in such a weapon comes from fission, so therefore it's called a boosted fission bomb
8. there is in theory no limits for how big a hydrogen bomb can be; you can just put more and more fusion material in it - I state that the real hydrogen bomb is the deadliest weapon ever made, and the biggest ever bomb test was the Tsar Bomba, which had an explosive power of 50 million tons of TNT (around 1500 times the total explosive power of both Hiroshima and Nagasaki combined)
9. the first hydrogen bomb was tested in 1952, by the USA - today there are at least five countries that have these types of weapons (USA, Russia, UK, France, and China)
10. this book is about the hydrogen bomb, and I got it from my sweet colleague, Gry, and now I'm going to read it <3

Happy weekend from Rose castle - we are going to watch West Wing and share a bottle of wine now :)

(I'm a frog :D)
