Assume a Spherical Cow is a STEM student’s place to soap box. I aim to share any ideas I think are engaging, no matter how unimportant they seem. Here, physics meets jokes, numbers meet nonsense, and the joy of scientific thinking matters more than whether the answer is useful. All pages are open to submissions.

Reccomendations

I have compiled essays, articles, movies, books, TV-shows, museums and competitions that are suitable for STEM students.

Rabbit Holes
I collect random, unrelated, esoteric facts and ideas. Use this page to explore the weirder corners of STEM.

Fermi Questions
Fermi Questions are strange, impractical, and often unnecessary estimation problems, like “how much would sea levels rise if everyone peed in the ocean?” and “How many pigeons would it take to lift the Empire State Building?” Let overestimations and underestimations balance out and lead you to a surprisingly accurate answer

Magic Tricks
Many magic tricks can be boiled down to simple maths concepts. Learn a few tricks and the maths behind them here.
