Beyond Euclid #191

Welcome to Beyond Euclid #191, the newsletter for the best mathematics and science stuff of the week. I am Ali, and I curate cool math and science stuff every week to help you have a better week.

Hello! While pulling together this week’s curiosities, I realized something: humanity spends its energy on some truly strange projects. Someone is turning 7,400 plastic bottles into a camper, someone else is filming a drop of espresso in slow motion, and another team is calculating that “a detour to the Moon makes going to Mars cheaper.” Meanwhile, nature is busy too—wolves return to a park and even the rivers change course.

The common thread in all these stories? A small idea or a single step can shift entire systems. A machine can lay sidewalks like a printer, a shopping bag can turn into giant glasses on the street, or a painting can become the unlikely ancestor of smartphone screens.

This week is once again full of inventions that make you think “why didn’t I come up with that,” scientific findings that seem too wild to be true, and nature’s quiet surprises.

Let’s dive in. And if you enjoy it, subscribe and share it with friends—because sometimes a small gesture makes all the differe…
