It took 125 years, but in 2025 a team of mathematicians discovered the solution to a long-puzzling problem about the ...

A college student in Switzerland says he’s solved a 100-year-old physics problem. The question is about an air bubble trapped in a very narrow tube of liquid, where the bubble appears to be “stuck,” ...

Compressible fluid dynamics investigates the behaviour of fluids when variations in density cannot be neglected, a scenario frequently encountered in high-speed aerodynamics and astrophysical ...

If you’ve ever whacked the bottom of a ketchup bottle to get that tasty tomato goop flowing, you’ve put some serious physics to work. Ketchup is a non-Newtonian fluid. So are toothpaste, yogurt, ...

In 1900, at the grand amphitheater of the Sorbonne in Paris, David Hilbert stood before a crowd of mathematicians and delivered a speech that would echo through the next century. He outlined 10 — and ...

Figure 1. A faulty flame disperser may cause the coils adjacent to the flame to absorb more heat energy than optimally designed. February 15, 2022 Heat transfer fluids are often taken for granted, ...
