• Prize for excellent measurements
  

  Anyone who has conducted precision measurements within the scope of a scientific project or assignment should pay close attention: You are eligible to apply for the Helmholtz Prize. It is Europe’s most prestigious award in metrology — the science of exact measurement — and will be awarded in two cat more

• Donuts and laser beams
  

  A donut is not a bun. From a mathematical point of view, they are two fundamentally different objects: The donut has a hole, the bun does not. A circle inside the donut around its hole in the center cannot be shrunk to a point. An arbitrary circle inside the bun, however, can. The mathematical disci more

• Neutrinos are lighter than 0.8 electron volts
  

  The international KArlsruhe TRItium Neutrino Experiment (KATRIN), located at Karlsruhe Institute of Technology (KIT), has broken an important "barrier" in neutrino physics which is relevant for both particle physics and cosmology. Based on data published in the prestigious journal Nature Physics, a more

When Water Levitates

Have you ever seen a drop of water navigate a maze? It’s possible thanks to a weird phenomenon called the Leidenfrost Effect. Understanding Leidenfrost — first described more than 200 years ago — helped engineers make more efficient steam engines. Today, scientists are using high-speed cameras t ... more

The Science of Fireworks!

Professor Chris Bishop, presenter of the 2008 Royal Institution Christmas Lectures, gives a family lecture on the history of the modern firework.Through demonstrations of pyrotechnic chemistry hear how Chinese incendiaries made from honey led to the development of gunpowder; discover how the lou ... more

The creation of tools made from laser light

After the Nobel Prize for Physiology or Medicine has been awarded, it is physics' turn. The 2018 Nobel Prize in Physics was awarded to Arthur Ashkin, Gérard Morou and Donna Strickland for their pioneering innovations in the field of laser physics. Strickland is only the third woman to receive the No more

Detecting gravitational waves from black hole collisions

This year’s second Nobel Prize in the sciences was awarded today. The prize for physics was awarded to researchers who contributed to the observation of gravitational waves, ripples in space-time that were originally created by colliding black holes over a billion years ago. more

The Chemistry of Sparklers

It’s Fireworks Night here in the UK tomorrow, which means fireworks (obviously), bonfires and sparklers. We’ve looked at fireworks in a previous post, so this time around it’s time to take a look at the chemicals that go into producing sparklers, and their various roles. In sparklers, there are thre more
