Our Earth is constantly bombarded with high energy particles and cosmic rays. These charged particles interact with the atoms in atmospheric gases, producing a cascade of secondary particles. And you can use those for dating rocks!
The Hessdalen Valley of Norway. Just 15 kilometres across. Low population density. But why is there a blue box perched high up on the hillside, with cameras covering the valley? What’s going on in this secluded valley?!
Greifswald, Northeastern Germany, 2016. Physicists at the Max Planck Institute have been racing to find a way of producing sustainable, clean energy with a stable nuclear fusion reactor. The challenge? Re-creating the Sun’s powerhouse on a much, much smaller scale.
For a while now, astrophysicists have known that our Universe is expanding, and accelerating. And much like the surface of a rubber balloon getting inflated, space is getting bigger, and bigger, and bigger…
The Universe never sleeps. Every now and then, the night sky presents us mere mortals with some heavenly spectacle. A Bonnie Tyler moment. This Friday, the Moon will enter the catwalk dressed in red to accomplish its otherwise normal nightly travel around the Earth. For one night only. A strange and rare celestial sight at dusk – a total lunar eclipse.
Our environment is permeated by radiation, present around us at all time. We are constantly exposed to radioactivity from natural sources for the most part naturally occurring radioactive nuclei in rocks and cosmic rays – the ‘background’. Without ado, this is my lowdown on radioactivity.
CERN’s LHCb collaboration has announced the discovery of a new “charming” particle, thought to be instrumental to the strong force – the Xi-cc++. Another particle. So…?
The Arecibo observatory is a very large radio telescope located in Puerto Rico. In 1974, astronomers used it to broadcast a message into outer space intended to demonstrate human intelligence. Why are we so interested in finding intelligence in the stars, and yet so deaf to the many species who manifest it here on Earth?
As the X-Files series enjoy a revival on TV, the American spy agency has decided to place thousands of declassified documents detailing government research into UFOs on its website. The CIA documents also confirm the reality of humans with ‘Special Abilities’ able to do seemingly impossible things.
Just over a century ago, Einstein proposed the existence of waves in the spacetime continuum – the logical deduction from his Theory of General Relativity. In February 2016, scientists finally announced the detection of those “ripples” in gravity, using the technique of laser interferometry.
Erm…No. Not Mona Lisa! (Rolls eyes.) Think again!! This is LISA – the Lisa Pathfinder satellite, the key element for a grand new project: a space-based gravitational observatory.
You know how when you throw a rock into a pool, that makes ripples in the water? And how Einstein once upon a time predicted that the very mass of stars and planets should warp spacetime? Although we have had a justified inkling that Einstein was right for quite some time, we had never before detected such a phenomenon. Until THIS happened…
Just like buses, it seems. But even rarer and a damn sight more exciting to be honest. Ooohoo!!! Out with your old Science books!! HeL-LOOooo elements 113… 115, 117 and 118!!
Already this article is beginning to sound like one of those sempiternal quizzes you so often get on social media… but it actually shows how science reality connects. Are you having a scientific identity crisis? Continue reading Lateral Thinking in Science – Who Are You?→
This blog is so cool. It’s spontaneous! It’s electric!! But not as cool as it has been at these cutting-edge laboratories on the outskirts of Europe. Scientists there are dealing with an entirely new type of solid matter – ‘spontelectrics’.
In the run-up to the 2015 physics Nobel prize, which was awarded on Tuesday 6 October, Physics World looked at how Nobel-prize-winning physicists have been moving around the globe over the past century.
With his wind-swept mane, the inimitable Richard Feynman looked devilishly handsome. And he darn-diddly knew it too! As for Fritz Haber, Rosalind Franklin and Neil deGrasse Tyson, they were the original hipsters. That’s according to BuzzFeed anyway… Continue reading Proving that Physicists were the Original Hipsters→
Let’s talk about size… 😉 How big are the objects floating in our Universe and how big can they get? Starting with a “big” object, our very own Moon… Embark on a tour of space… A tour of our Universe…
First predicted in the 1960s, like the Higgs boson before it, the pentaquark eluded science for decades until its recent detection at CERN’s LHCb collaboration. The discovery amounts to finding a new form of matter…
1/60 minute. 1/3,600 hour. 1/86,400 day. 1/1 hertz. The duration of 9,192,631,770 periods of the radiation corresponding to the transition between the two hyperfine levels of the ground state of a 133 55Cs caesium isotope corresponds to one second. But what does it look like? And where might you find a second?
Deep down, in huge subterranean caverns… Underneath the Franco-Swiss border… 300 feet underground… lies a beast of unprecedented power… and mystery. The Large Hadron Collider (LHC) that man summons to explore the uncharted corners of the sub-atomic realm… After two years of a deep slumber, the mighty beast has awoken…
