In physics or engineering education, a Fermi problem, Fermi quiz, Fermi question, Fermi estimate, order-of-magnitude problem, order-of-magnitude estimate, or order estimation is an estimation problem designed to teach dimensional analysis or approximation of extreme scientific calculations, and such a problem is usually a back-of-the-envelope calculation. The estimation technique is named after physicist Enrico Fermi as he was known for his ability to make good approximate calculations with little or no actual data. Fermi problems typically involve making justified guesses about quantities and their variance or lower and upper bounds. In some cases, order-of-magnitude estimates can also be derived using dimensional analysis. (Wikipedia).

Teach Astronomy - Solutions to the Fermi Paradox
http://www.teachastronomy.com/ The Fermi Paradox starts with the simple question, where are they? It's based on the huge number of potential sites for life and the large amount of time in the history of the universe for intelligent civilizations that can travel in space to have developed.

Making ferrofluid from scratch
Back in October, I tried making ferrofluid but I kept failing and I ended up giving up for a while. Months later though, I got inspired, and I spent an insane amount of time researching ferrofluid and trying to make it. It was a very messy and sometimes frustrating process, but I was event
