The theory of relativity works well when you want to explain cosmic-scale phenomena—such as the gravitational waves created when black holes collide. Quantum theory works well when describing particle-scale phenomena—such ...

In physics, one often has to deal with different scales that can be described separately from one another: For the Earth's orbit around the sun, it makes absolutely no difference whether an elephant in the zoo walks to the ...

For two decades, it was believed that a possible quantum spin liquid was discovered in a synthetically produced material. In this case, it would not follow the laws of classical physics even on a macroscopic level, but rather ...

Thinking of CO2, terms like climate-damaging or waste product probably quickly come to mind. While CO2 has been that for a long time—a pure waste product—more and more processes are being developed with which the greenhouse ...

Normally, we have to make a choice in physics: Either we deal with big things—such as a metal plate and its material properties, or with tiny things—such as individual atoms. But there is also a world in between: The ...

Using lasers to slow down atoms is a technique that has been used for a long time already: If one wants to achieve low-temperature world records in the range of absolute temperature zero, one resorts to laser cooling, in ...
