I want to know the answer to the following question:
On what day was the first atomic blast?
All the background I'm provided with is that "Based on his observation alone, von Neumann estimated the test had resulted in a blast equivalent to 5 kilotons of TNT (21 TJ) but Enrico Fermi produced a more accurate estimate of 10 kilotons by dropping scraps of torn-up paper as the shock wave passed his location and watching how far they scattered.". Is that enough to answer the question?
Answer: no
