The intricate relationship between quantum mechanics and classical physics has long puzzled scientists. Quantum mechanics operates in a bizarre world where particles can exist in multiple states ...

In the forbidden fried egg image, the yolk is whats known as a Bloch sphere, and represents the classical geometry version of what happens in a qubit. It’s the entire range of possible behaviors ...

PHI 538, Metaphysics of Physics Seminar Leaders: H. Halvorson and J. Butterfield Meeting time: Wed, 6:00-8:50pm Description. In the first half of the semester, we will discuss philosophical problems ...

Their finding suggests that the classical world we see can emerge from the many-worlds picture of quantum mechanics, where ...

According to him, “symplectic geometry was born as a geometric language of classical mechanics”. Students are taught in schools to solve classical mechanics problems using Newtonian mechanics.

The new model may explain why our universe's space-time geometry doesn't exist in a superposition of states and obeys the classical equations of Einstein's relativity.

A new paper gives fellow quantum physicists a tool to help explore the geometry of the universe. They say one qubit’s behavior, regardless of its starting position, forms a predictable geometric ...

The Nature Index 2025 Research Leaders — previously known as Annual Tables — reveal the leading institutions and countries/territories in the natural and health sciences, according to their ...

In spite of this strong experimental evidence, scaling laws on the strength of solids usually ignore geometry and are studied by applying mechanics (see ref. 5): in particular, fracture mechanics ...
