The "failure in the war" part refers to German scientists back in the WWII, who had erroneously estimated the required critical mass for a self-sustained chain nuclear fission reaction to be many times larger than it was in the reality (they kinda modelled the process in the wrong way, the probability of the neutron hitting the nuclei in some random U-235 brick was way higher). Hence, they thought that collecting so much of U-235 isn't feasible. The bright minds of the USA and, a little bit later, USSR (many of whom were chased out from Germany prior to the war, ironically) were a lot more clever, and it was only a matter of time before the more powerful fusion bombs (which abused the high energy spike between deuterium+tritium and the resulting alpha-particles - Helium-4) were developed in USSR and, a little bit later, the USA.
Lucia : I am going to be praised by Witch Association , Boom creates Nuclear Weapon Materials near their Home
Witches : 🤨😮😨
Lucia : Stares at Roland and then at Witches but but I didn't know Crys and Runs away 😌
Im an Electronics Engineering Student about to graduate yet Im not even comparable to roland whose knowledge in engineering, physics, and chemistry rivals that of stephen hawkings!
Haha the reaction of the witches was priceless but honestly you could never pay me enough to ever enter into a room full of the one element that could turn me into an extra crispy side of of human french fries
I'm amazed people here don't think all this isn't a part of high school chemistry and physics O_o this is all mentioned in Asian high school curriculum
