In this video, we’ll break down how to solve physics problems involving the motion of a 2D spring. Learn about the forces at play, how to model the spring’s movement, and the key concepts behind ...
In this video, we break down the classic physics problem of a block on an incline with friction. Learn how to calculate the forces at play, including gravitational force, normal force, and frictional ...
It took 125 years, but in 2025 a team of mathematicians discovered the solution to a long-puzzling problem about the ...
Even most rocket scientists would rather avoid hard math when they don't have to do it. So when it comes to figuring out ...
Imagine Jo: Everyone in Jo's life recognizes her as an outstanding problem solver. She's the type of person who seems capable ...
When you splurge on a cocktail in a bar, the drink often comes with a slab of aesthetically pleasing, perfectly clear ice.
More than 200 years ago, Count Rumford showed that heat isn’t a mysterious substance but something you can generate endlessly ...
The Defiance Quantum ETF QTUM provides broad exposure and trades at roughly 23 times cash flow. Not cheap, but not insane for a sector where winners might return 50 times. It's up almost 40% so far ...
After completing your single task (and taking a break to acknowledge your progress), you move to the next concrete action.
In a short talk at Caltech, physicist Richard Feynman laid out a vision of manipulating and controlling atoms at the tiniest ...
An experiment with ultracold atoms reveals that a strongly driven quantum system doesn’t always heat up as expected. In daily life, doing work on something over and over usually makes it warmer. You ...
