Max Planck and how the spectacular birth of quantum physics changed the world

Max Planck and how the spectacular birth of quantum physics changed the world

This is the first in a series of articles exploring the birth of quantum physics. We now live in the digital age. The landscape of technological wonders that surrounds us is something we owe to a hundred physicists who, at the dawn of the 20e century, were trying to figure out how atoms worked. They …

First lead ion collisions in the LHC at record energy

On Friday 18 November, a test using lead ion collisions was carried out in the LHC and allowed the experiments to validate the new detectors and the new data processing systems before the next lead-lead physics campaign. Run3’s first Pb-Pb collision event displays taken on November 18, 2022 (Picture: CERN)After the successful start of Run …

Quantum algorithms save time in calculating electron dynamics

Quantum algorithms save time in calculating electron dynamics

The calculations make it possible to determine the electron densities and the changes after excitation with high spatial and temporal resolution. Here, the example of the lithium hydride molecule shows the shift in electron density from cyanide (red) to lithium (green) during a laser pulse. Credit: F. Langkabel / HZB Researchers investigated the ability of …

New study sheds light on ocean dark matter

The new findings suggest that marine microbes use photosynthesis. Photosynthesis is used by marine bacteria to absorb carbon dioxide. Scientists may be able to determine whether or not ocean bacteria are involved in the global carbon cycle by determining whether or not marine microbes use photosynthesis Photosynthesis is the way plants and some microorganisms use …

Brain experiment suggests consciousness relies on quantum entanglement

Brain experiment suggests consciousness relies on quantum entanglement

Supercomputers can beat us at chess and perform more calculations per second than the human brain. But there are other tasks our brains do on a regular basis that computers simply can’t match – interpreting events and situations and using imagination, creativity and problem-solving skills. Our brains are amazingly powerful computers, using not only neurons …

An expert offers a method to find out if we all live in a computer program

Physicists have long struggled to explain why the Universe began with conditions conducive to the evolution of life. Why do physical laws and constants take on very specific values ‚Äč‚Äčthat allow stars, planets, and ultimately life to develop? The expanding force of the Universe, dark energy, for example, is much weaker than theory suggests – …

Einstein's predictions for gravity have been tested on the largest possible scale

Einstein’s predictions for gravity have been tested on the largest possible scale

According to the standard model of particle physics, the universe is governed by four fundamental forces: electromagnetism, the weak nuclear force, the strong nuclear force and gravity. While the first three are described by quantum mechanics, gravity is described by Einstein’s theory of general relativity. Surprisingly, gravity is the one that presents the greatest challenges …
