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! Continue reading Dating Rocks – Methods of Historical Surface Exposure Analysis

Identifying the Unidentified – The Hessdalen Light Phenomenon, Norway
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?! Continue reading Identifying the Unidentified – The Hessdalen Light Phenomenon, Norway
Engineering A Star – Nuclear Fusion, Tokamaks and Stellarators
A Stellar Reactor
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. Continue reading Engineering A Star – Nuclear Fusion, Tokamaks and Stellarators
Nine – The Elusive Planet in Our Solar System
A hypothetical Ninth planet has been lurking on the outskirts of our Solar System. But Planet Nine may not be a planet at all… Continue reading Nine – The Elusive Planet in Our Solar System
The Universe Expands Far Faster Than Anticipated…
The Universe is accelerating
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… Continue reading The Universe Expands Far Faster Than Anticipated…
Crimson Moon – A Total Lunar Eclipse
The Motion of Celestial Spheres
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. Continue reading Crimson Moon – A Total Lunar Eclipse
Radioactivity and the Background of Dancing Particles
Natural Radiation
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.

Charming New Particle Xi-cc++ Discovered at CERN
The Xi-cc++ Particle
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…? Continue reading Charming New Particle Xi-cc++ Discovered at CERN
Arecibo and the Great Silence – Where We Talk About a Parrot Named Alex
Arecibo – What a Dish!
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?

CIA Releases “X-Files”
The Real X-Files
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. Continue reading CIA Releases “X-Files”

2016: Another Year in Cutting Edge Science
You Spin Me Right Round…
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. Continue reading 2016: Another Year in Cutting Edge Science
Hunting Ripples in the Fabric of Space-Time – The Trials and Tribulations of LISA
Meet LISA!
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. Continue reading Hunting Ripples in the Fabric of Space-Time – The Trials and Tribulations of LISA
The Discovery of Gravitational Waves – Merging Black Holes and Advanced LIGO
Black Holes Far Ago Have Been Causing a Stir…
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… Continue reading The Discovery of Gravitational Waves – Merging Black Holes and Advanced LIGO
You Wait Ages for a Chemical Element, and Then… BINGO!!
Four Elements Come Along at Once…
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!! Continue reading You Wait Ages for a Chemical Element, and Then… BINGO!!
Lateral Thinking in Science – Who Are You?
What kind of Scientist are you?
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?
What’s the Matter… with Spontelectrics?
Spontelectrics
This blog is 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’. Continue reading What’s the Matter… with Spontelectrics?

It’s Nobel Prize Season Again!
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. Continue reading Physics Without Frontiers…
Proving that Physicists were the Original Hipsters
Modern-Day Hipsters Take Heed…
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
Exoplanet ‘Young Jupiter’ 51 Eridani b
King of Planets

Size Matters… in Astrophysical Terms
Little Big Earth and the Universe
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… Continue reading Size Matters… in Astrophysical Terms
Behold… the Mystical Pentaquark! – More Exotic Matter Discovered at CERN
Pentaquark… Eh, WHAT?!
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… Continue reading Behold… the Mystical Pentaquark! – More Exotic Matter Discovered at CERN
Just a Second…
What Does a Second Look Like?
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? Continue reading Just a Second…
Physics at 13 TeV – Cranking Up the LHC
A Vernesque Feat of Human Engineering
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… Continue reading Physics at 13 TeV – Cranking Up the LHC
