| 0:16.2 | On July 16th, 1945, at 529 AM, 35 miles south of Socorro, New Mexico, the world's first atomic bomb was detonated. |
| 0:17.5 | This was the culmination of the Manhattan Project, one of the largest and most expensive programs |
| 0:21.9 | in world history. |
| 0:23.0 | Yet before the event, scientists and engineers who worked on the project |
| 0:27.0 | were entirely certain it would work, and if it did, just what the results would be. |
| 0:31.0 | Learn more about the Trinity Test, the world's first atomic bomb detonation, on this episode |
| 0:35.8 | of Everything Everywhere Daily. The story of the Manhattan Project is not one that can easily be covered in a single episode of this podcast. |
| 0:57.0 | The cost of the project was staggering at a time when a billion dollars was still a lot of money. |
| 1:03.6 | The number of people who worked on the project was likewise staggering, especially considering |
| 1:07.7 | that the United States was in the middle of a globe-spanning two-front war. |
| 1:11.8 | While the theoretical science behind making a bomb was known, it was a far cry |
| 1:15.5 | between knowing it could theoretically be done and actually doing it. There were several debates |
| 1:20.4 | amongst the scientists in the Manhattan Project as to how a bomb could and should be built. several debates about |
| 1:23.3 | could and should be built. |
| 1:25.0 | There were different theories as to what course of action they should take. |
| 1:28.0 | It wasn't just a matter of what could work, but also what would be the easiest to build on the most effective. |
| 1:34.0 | There were two competing designs that were debated in the program, |
| 1:37.0 | and before I get into what these designs were, I need to explain the concept of critical mass and supercriticality. |
| 1:44.3 | For a nuclear reaction you need to have an isotope of some radioactive element which is considered |
| 1:48.5 | fissile. A fissile isotope is one that will split after capturing a neutron. |
| 1:53.9 | In the process of splitting, it will then give off more than two neutrons on average. |
| 1:58.6 | Those neutrons will split even more atoms, ejecting more neutrons, causing a chain reaction. However, the ability of that |
