On the whole, Earth scientists agree that melting of land ice greatly contributes to sea-level rise.  And one thing’s for sure.  Future global warming will exacerbate the risks posed to human civilisation.  But…  What if you could forecast major floods?  You can.  Continue reading Future Floods and Melting Ice Sheets – Predicting with GRACE

Sailing the Lower Midnight… – The Uncharted Frontier of Modern Deep-Sea Exploration

A photograph of the not-so-friendly, and frankly scary-looking, footballfish, a deep sea-predator from the anglerfish family.What lies 5,000 metres Below Sea Level?

It’s cold down there.  Icy cold.  It’s dark.  Pitch black, in fact.  And the crushing pressures make the deepest parts of the oceans into some of the most hostile places on our planet.  The lowest of the low.  The deepest of the deep.  Only three human explorers ever made it down there.  As a brand new wave of deep-sea exploration begins, we look at the mysterious world where marine scientists will be diving into… Continue reading Sailing the Lower Midnight… – The Uncharted Frontier of Modern Deep-Sea Exploration

A Theory of Life… The Physics of Cells and Macroscopic Irreversibility

A meme that reads: "Life has No Ctrl + Z".“It’s Life!  But Not as We Know it…”

There is one essential difference between living things and inanimate clumps of carbon atoms.  From an all-physical point of view, the former tend to be so much better at capturing energy from their environment and dissipating that energy as heat.  At MIT, Jeremy England derived a mathematical formula that he believes explains this capacity.  Continue reading A Theory of Life… The Physics of Cells and Macroscopic Irreversibility

The Discovery of Gravitational Waves – Merging Black Holes and Advanced LIGO

An animation illustrating two colliding and merging black holes in outer space.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

Name: Tim Peake Job: Space Electrician

A selfie photograph taken by British astronaut Major Tim Peake of himself during his historic first space walk outside the International Space Station on 15 January 2016. The British Union flag is visible on the left shoulder of his pressure suit, as well as a view of the Earth being reflected in his visor. Spaceman, I always wanted you to go into space, man!

After nearly five hours in space, British astronaut Tim Peake completed his first spacewalk, at 17:31 GMT on Friday 15 January.  Intended to last over six hours, the space walk was cut short after his US colleague Tim Kopra reported a water leak in his helmet.

Lateral Thinking in Science – Who Are You?

A photographic montage showing Laura Dern, Benedict Cumberbatch and Lennie James in various cinematic and TV roles as scientists. The caption asks: "What kind of scientist should you be?"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?

Proving that Physicists were the Original Hipsters

A black and white photograph of Nobel physicist Richard Feynman, pictured smiling in front of the blackboard of a lecture room, which is covered with mathematical equations.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

We Check the Time of Death with Post-Mortem Degradation of Skeletal Proteins – And Other Gruesome Forensic Facts of Life

A photomontage showing a body outline, "Do Not Cross" yellow police tape, and a magnifier focused on the word "Forensics". The picture also lists the following forensic ways to estimate the time of death - Wait: Determine the time of death; Rigor mortis; Decomposition; Forensic Entomology; Succession on corpses; Other decomposers.Estimating the Time of Death

Forensic researchers from the University of Salzburg have developed a new method for establishing an exact time of death after as long as 10 days – a significant step forward from the current method of measuring core body temperature, which only works up to 36 hours after death. Continue reading We Check the Time of Death with Post-Mortem Degradation of Skeletal Proteins – And Other Gruesome Forensic Facts of Life

Just a Second…

A close-up photograph of an analog clock showing the hands just reaching the hour.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?

That Mysterious Missing Matter – Cocktail Party Physics

A 3D animation showing dark matter creation and the large scale structure of the Universe.Dark Matter

“Dark matter?”  You cannot see it.  But there is something there.  As for what it is, it’s anybody’s guess!  Dark matter does not interact with light.  At all.  Which makes it difficult to detect.  But if you cannot see it?  How do you know it is in fact there?”  Well, it does interact with gravity, and as it does so it bends the path of any light ray passing nearby...  “And did it really kill the dinosaurs…?”  Continue reading That Mysterious Missing Matter – Cocktail Party Physics
