Structure is key, when it comes to properties. And in so called metamaterials, scientists and …
We usually assume that The Great Unknown lies somewhere near the poles, or deep in the jungle or elsewhere in the universe.
But in fact much of it lies in things we can hold in our hands: in magnets and crystals and cells, and in future materials that we have barely learnt to make, like superconductors, nano engines, quantum computers.
These things are full of mysteries. To unravel them is the task of the scientists and engineers at HZB. These things are also very small. The only way to look at them is with really big machines.
Some of those are being built at HZB right now.
These are their stories.
In a previous post, we assumed the lifetime of neutrons is around 15 minutes before they decay. That is true. But if you look a bit closer, the picture becomes more complicated. The physicists Geoffrey L. Greene and Peter Geltenbort reported in an article for "Spektrum der Wissenschaft" that they measured with two different methods a lifetime discrepancy of 9 seconds. That is a large difference …
As I left EMIL, I could not stop from reflecting to Núria’s words and wonder: how is it possible that part of the World’s population still refuses to accept that the World’s primary energy demand increases and the Climate Change is getting worse, regardless of the fact that researchers and environmentalists work non-stop to tackle these problems? How many more fancy machines and lab equipment do …
