Alex Wellerstein has another compelling slideshow at the Bulletin, this time commemorating this week's 68th anniversary of the Trinity nuclear test. Wellerstein points out that at this point in the project, the bomb was not a forgone conclusion, and it's abilities were largely guesses (including the most basic question of how explosive the blast would be). Please check it out and let us know what you think!
