Quantum theory needs complex numbers

Physicists construct theories to describe nature. Let us explain it through an analogy with something that we can do in our everyday life, like going on a hike in the mountains. To avoid getting lost, we generally use a map. ...

Quantum simulation: Measurement of entanglement made easier

University of Innsbruck researchers have developed a method to make previously hardly accessible properties in quantum systems measurable. The new method for determining the quantum state in quantum simulators reduces the ...

Cybersecurity pioneers win mathematics Abel Prize

The Abel Prize, which honours achievements in mathematics, was awarded Wednesday to Hungarian Laszlo Lovasz and Israeli Avi Wigderson for their contributions to computer security, the Norwegian Academy of Science said.

Exponential scaling of frictional forces in cells

AMOLF researchers have presented a theory that describes the friction between biological filaments that are crosslinked by proteins. Surprisingly, their theory predicts that the friction force scales highly nonlinearly with ...

Newly identified gene reduces pollen number of plants

Producing fewer sperm cells can be advantageous in self-fertilizing plants. An international study led by the University of Zurich identified a gene in the model plant Arabidopsis that reduces the amount of pollen. In addition ...

An inmate's love for math leads to new discoveries

There are many examples of mathematical breakthroughs achieved in prison. Maybe the most famous is from the French mathematician Andre Weil, who came up with his hugely influential conjectures while in a military prison in ...

'The Big Bang Theory' takes math notes from Carl Pomerance

A prime number theory equation by mathematics professor emeritus Carl Pomerance turned up on The Big Bang Theory, where it was scrawled on a white board in the background of the hit sitcom about a group of friends and roommates ...
