☆ How hydrogen bombs compare to atomic bombs, and how scientists created the most destructive weapon ever

Hydrogen bombs and atomic bombs are both nuclear weapons that can cause mass destruction. But just seven years later an even more destructive nuclear bomb was built — the hydrogen bomb. Whereas hydrogen bombs get their power from a combination of fission and its opposite — nuclear fusion — the binding of atoms. Hydrogen vs. atomic bombs: damage and destructionWhile atomic bomb blasts are measured in kilotons — 1 kt is equivalent to the explosive force of 1,000 tons of TNT — hydrogen bombs are often measured in megatons.

☆ How atomic bombs work and why Manhattan Project scientists designed two types of bombs during WWII
▼ + stars: | 2023-08-09 | by ( Adam Barnes | ) www.businessinsider.com time to read: +7 min

Atomic bombs work via a process called nuclear fission that involves atom splitting. Albert Einstein didn't make the first atomic bombs, but his famous equation explains how they work. Scene from the film "Oppenheimer," where Cillian Murphy stands next to the first ever atomic bomb to detonate. The scientists designed and completed two different types of atomic bombs because they weren't sure which method would work. Since scientists working on the Manhattan Project weren't quite sure if the plutonium bomb's implosion method would work, they decided to test one before it was used in the war.

☆ I used a 'light hypnosis' app for a month. It helped my productivity, but I was more blown away by what it did to my downtime.

Julie Peck is a freelancer who was having trouble focusing on tasks, so she tried the app BrainTap. Similar audio programs are available for free on YouTube and Spotify, as well as on rival meditation apps like Insight Timer, Sacred Acoustics, and EquiSync. BrainTap app screenshot.

☆ Письмо Эйнштейна с уравнением E=mc2 продано за $1,2 млн

Написанное от руки письмо Альберта Эйнштейна, содержащее его знаменитое уравнение E=mc2, было продано на аукционе за $1,2 млн. «Это важное письмо как с голографической, так и с физической точки зрения», — сказал исполнительный вице-президент RR Auction Бобби Ливингстон. Рукописное письмо на немецком языке, состоящее из одной страницы, было адресовано польско-американскому физику, критику и оппоненту ученого Людвигу Зильберштейну. В письме Эйнштейн заявил адресату, что на его вопрос можно ответить формулой E=mc2, «без всякой эрудиции». Уравнение – энергия равна массе, умноженной на квадрат скорости света, – изменило физику, доказав, что время не является абсолютным и что масса и энергия эквивалентны.
