9 Good Collections of Videos for Education

Ask a Tech Teacher

Bright Science is a free YouTube channel of over 1300 study videos for high schoolers (or precocious middle schoolers). Most are about five minutes (some longer, some shorter) and cover topics like chemistry, physics, calculus, geometry, biology, Algebra, trigonometry, grammar, ACT prep, and SAT prep.

Numbers and networks: how can we use mathematics to assess the resilience of global supply chains?

Futurum

Governments and companies want to do something,” says Zach. There are many branches of maths, including algebra, geometry, calculus and statistics. Global supply chains are still recovering from the cascading failures caused by these disruptions. WHAT DOES A DAY IN THE LIFE OF A MATHEMATICIAN LOOK LIKE?

How Did We Get Here? The Tangled History of the Second Law of Thermodynamics

Stephen Wolfram

In 1845 Kelvin (as we’ll call him) had spent some time in Paris (primarily at at a lab that was measuring properties of steam for the French government), and there he’d learned about Carnot’s work from Clapeyron’s paper (at first he couldn’t get a copy of Carnot’s actual book). But first we have to go back a bit in the story.

The Concept of the Ruliad

Stephen Wolfram

And just like the speed of light governs the maximum rate at which effects can propagate in physical space, so similarly in our models there’s a “ maximum entanglement speed ” at which effects can propagate in branchial space. But what about other models of computation—like cellular automata or register machines or lambda calculus?

What Is ChatGPT Doing … and Why Does It Work?

Stephen Wolfram

But say all we’ve got is the data, and we don’t know what underlying laws govern it. It’s not obvious that it would be feasible to find the path of the steepest descent on the “weight landscape” But calculus comes to the rescue. In this particular case, we can use known laws of physics to work it out.
