Ever get lost in all those mathematical “spaces”?
This beautiful diagram maps the full hierarchy from the wildest to the most familiar. Topological spaces are defined only by open sets. Metric spaces add distance. Vector spaces allow linear combinations. Normed spaces measure size while inner product spaces add angles.
At the core sits Euclidean R^n, the complete geometry of our everyday world.
In general relativity, matter tells spacetime how to curve.
You input information about matter, and the theory tells you how space curves and how time runs around it. In other words, time is part of the output.
Researchers using the Event Horizon Telescope @ehtelescope have improved the resolution of black hole images by 50% using higher frequencies (345 GHz) and combining data from telescopes in Spain, Hawaii, and Chile. This advancement will allow scientists to capture more detailed images of black holes, revealing new insights into their structure and behavior.
The enhanced resolution is comparable to seeing a large coin on the Moon from Earth. This breakthrough promises to uncover previously hidden details about black holes.

(This simulation shows how the supermassive black hole images might change in a few years)
Tensors are instrumental in physics, machine learning and even biology. Einstein once begged a friend to help him understand them, fearing he was going mad. Joseph Howlett explains how they work: https://t.co/OAkmeNPoEl
If you love it, go for it. You are enough. You're smart enough. You're putting in the hard work. Failing is okay, it's all about standing up and continuing after. We all follow our own paths, but they all lead somewhere. Anyway, happy holidays!
