The threat of the atomic bomb may not seem so bad in the beginning because its destructive power is underestimated, people are not fully aware of its long-term effects, and there is a sense of distance from the actual devastation. Additionally, there may be a belief that the bomb would only be used as a last resort in extreme circumstances.
Bert the Turtle appeared in filmstrips featuring a cheery little jingle called "Duck and Cover". The films suggested that it was possible to survive an atomic bomb simply by, well, ducking and covering the back of your neck with your head. This would do approximately nothing for people close to the blast, but they likely wouldn't have time to do it anyway, and against conventional explosives or at some distance from a nuclear blast, it would help mitigate the immediate effects.
Please note that every property of an element depends on protons so one property is often hard to sort out from another since each property has its own trends in relation to the number of protons (atomic number). The first property that indicates the number of protons is a nanoscopic one, atomic width. A property that can indicate the relative number of protons is density. That is chemical density not structural density. Air voids in a solid can make the density seem smaller. Most solids (that is, true solids devoid of air gaps and porosity) are heavier than water. So if you wanted to find density differences in known solids (and reative atomic numbers) you would hit the object with x-rays and record the relative amounts that came through to the exposure film. If you have access to a Scanning Electron Microscope using primarily the back scatter contrast method can give you an image depicting relative differences in density. Remember though it must be a true solid. Many elements have isotopes which essentially are more dense atoms withe the same atomic number. These elements are still relatively close to the non-isotopic element since there is no absolute way to.
Things may seem louder at night because there is less ambient noise to mask the sounds, making them more noticeable and prominent.
On nuclear fission, small fraction of mass is loss and transform to energy. The loss mass is part of tiny sub-atomic particle. Consider reaction of Uranium U235 + n1 --> U236 --> Kr92 + Ba141+3n1 Well seem all mass is balance. But take careful step U235 is 235.0439 U236 is 236.0526 Kr92 is 91.92616 Ba141 is 140.9144 n is 1.008665 Some mass was lost and that mass go to energy as Einstein state E = mC2
It may seem harder to start sliding a couch because of the friction between the couch and the floor. The weight and size of the couch can make it more difficult to overcome this friction and get it moving.

It blew people to bits stopping the war. And looked cool... Along with making the U.S. seem stronger.
The video uses animation and song to make the atom bomb seem not so bad.
The video likely employs various techniques to downplay the threat of the atom bomb, such as using light-hearted language, humor, or visual effects that minimize its destructive power. It may also focus on the scientific aspects and technological advancements associated with nuclear energy, presenting them as beneficial rather than dangerous. Additionally, the video might highlight the concept of deterrence, suggesting that the bomb serves as a protective measure rather than a threat. Overall, these strategies aim to create a more benign perception of the atom bomb.

They are the same kind of bomb: bombs that derive their energy from the atomic nucleus. It just depends on design and how much of the design yield is from fission or from fusion. Pure fission bombs cannot be built with yields above 1 megaton, but including some fusion the theoretical yield is unlimited.However considering mission, construction costs, size limits, etc. it is usually more practical to build low yield bombs that are part fission part fusion than to try to build high yield bombs of either type.The lowest yield nuclear bomb tested was the US Davy Crocket at 10 tons yield, the highest yield nuclear bomb tested was the USSR Tsar Bomba at 52 to 58 megatons yield (depending on method of measurement). Both were part fission part fusion designs, although the designs were obviously very different: the Davy Crocket was almost entirely fission yield, the Tsar Bomba was over 95% fusion yield and generated the least fallout per kiloton yield of any nuclear bomb detonated in the atmosphere.

A lot of people seem to think Revan. reven is da bomb
