The Trinity Test: The World's First Atomic Bomb Detonation
TLDR On July 16, 1945, the world's first atomic bomb was successfully detonated at the Trinity test site in New Mexico. The test marked the end of the Manhattan Project and brought a sobering realization of the power and implications of atomic weapons.
Timestamped Summary
00:00
The world's first atomic bomb was detonated on July 16, 1945, and before the event, scientists and engineers were uncertain if it would work and what the results would be.
02:06
The design of the first atomic bomb, known as a gun-type fission weapon, involved forcefully expelling a projectile made of uranium-235 towards a cylinder of uranium-235 in order to achieve supercriticality and create an atomic explosion.
04:05
Richard Tolman proposed an implosion-type design for an atomic bomb, which involved compressing a seed of fissile material inside a conventional explosion in order to achieve supercriticality and release more energy, leading to the reconsideration of the gun-type design.
06:08
The Manhattan Project received approval for a full-scale test of the atomic bomb, despite concerns about the cost and the risk of wasting plutonium, and they selected the Alamogordo bombing range in New Mexico as the site for the test.
08:03
The Trinity Test involved the transportation of a large object by rail, the creation of special bunkers and viewing areas, a rehearsal explosion, and the assembly of the bomb known as the gadget on top of a steel tower.
10:03
On July 16th, 1945, the world's first atomic bomb was detonated at the Trinity test site, producing a larger explosion than predicted and turning the sand underneath into a glassy substance called Trinitite.
11:56
The Trinity test site, where the world's first atomic bomb was detonated, is restricted to visitors due to ongoing missile tests, and the test marked the end of the Manhattan Project and brought a somber realization of the implications of their actions.
