Editor’s Note: Professor WERNER HEISENBERG, who was born in Duisburg in 1901, was awarded the Nobel Prize in Physics in 1932 for his work on the quantum theory. A member of the faculty of the ...

Planck's constant reveals the quantum world's fundamental energy levels. It shows how light and matter exist in discrete units (quanta). This constant defines limits to our knowledge of particle ...

The dominant view in physics is simple: the laws of nature are fixed. Gravity pulls as it always has; quantum probabilities collapse with the same stubborn indifference today as billions of years ago.

The following is an extract from our Lost in Space-Time newsletter. Each month, we hand over the keyboard to a physicist or two to tell you about fascinating ideas from their corner of the universe.

The almost impossibly brief Planck time has been known since the 19th century. Originally dismissed as a mere curiosity, it may hold the key to understanding the universe. When you purchase through ...

Neutrinos may be nearly invisible, but they play a starring role in the Universe. Long-standing anomalies had hinted at a ...

Is the universe thinking and learning on some level? This is a thorny subject, but one that some researchers are willing to consider. According to research that was published in the pre-print server ...

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

For the first time, scientists have observed electrons in graphene behaving like a nearly perfect quantum fluid, challenging a long-standing puzzle in physics. By creating ultra-clean samples, the ...
