Why do balls untwist?

Explore the physics behind why twisted balls untwist on their own. Discover the surprising forces and motion at play in this simple but fascinating experiment.
Patrick Stump has returned to his hardcore roots with the Fall Out Boy vocalist making an appearance during Weekend Nachos’ show last Friday.
From Newton’s falling apple to Einstein’s curved spacetime, our understanding of gravity has come a long way, yet this ...
B ack in 2019, researchers observed a collision between two black holes of wildly different masses. New analysis has revealed that the collision produced a massive recoil, sending the newly formed ...
The researchers found that only Arctic diatoms can move through actual ice. Temperate diatoms (species from warmer waters) ...
Earth’s radiation can send some molecules spinning or vibrating, which is what makes them greenhouse gases. This infographic ...
So the bottom line is that the gravity of the closer tidal bulge on the Earth is pulling the Moon forward, which increases the size of the Moon’s orbit. This means that the Moon gets slightly farther ...
Tides come from a difference in gravity across an object. The force of gravity exerted by the Moon is about 4% stronger on the side of Earth that faces toward the Moon, compared to the opposite side ...
It sounds like a trick of science fiction: particles springing into existence out of thin air. For decades, the so-called ...
The speed of light, c, is not just a very large number. In modern physics it is a structural constant: the conversion factor ...
Early scientific theories—such as those explaining basic phenomena like gravity, burning, and the movement of molecules in water—centered on presumed inherent properties rather than external factors, ...
A whole-body control foundation model could help launch humanoid robots toward general-purpose capability, says Agility ...
