Hi, guys! I am a high school senior, I would like to ask you a few questions about how to measure the released energy during physics experiments, especially both nuclear reactions.

Also, how could Fermi just know the "yield" just by a handful of torn paper?

As the shock wave hit Base Camp, Aeby saw Enrico Fermi with a handful of torn paper. "He was dribbling it in the air. When the shock wave came it moved the confetti. He thought for a moment."

Fermi had just estimated the yield of the first nuclear explosion. It was in the ball park.[13]


Fermi's strips-of-paper estimate was ten kilotons of TNT; the actual yield was about 19 kilotons

Thanks for your reading!
