Does the quantum wave function represent reality?

(Phys.org) -- At the heart of quantum mechanics lies the wave function, a probability function used by physicists to understand the nanoscale world. Using the wave function, physicists can calculate a system's future behavior, ...

Explaining gravity without string theory

For decades, most physicists have agreed that string theory is the missing link between Einstein's theory of general relativity, describing the laws of nature at the largest scale, and quantum mechanics, describing them at ...

Novel theory addresses centuries-old physics problem

The 'three-body problem,' the term coined for predicting the motion of three gravitating bodies in space, is essential for understanding a variety of astrophysical processes as well as a large class of mechanical problems, ...

Tricking the uncertainty principle

(Phys.org) —Caltech researchers have found a way to make measurements that go beyond the limits imposed by quantum physics.

Green conversion of heat to electricity

Soon, it will be possible to produce electricity from heat over 30 degrees emitted from a waste incinerator, refinery, or data processor. The start-up Osmoblue has just confirmed the feasibility of this new concept.

Mechanical micro-drum cooled to quantum ground state

Showcasing new tools for widespread development of quantum circuits made of mechanical parts, scientists from the National Institute of Standards and Technology have demonstrated a flexible, broadly usable technique for ...

Students develop a low-cost portable ventilator

(PhysOrg.com) -- A team of students from MIT has devised a new low-cost ventilator to keep patients breathing in places that lack standard mechanical ventilators, or during times of emergency such as pandemics or natural ...
