Crimson Moon – A Total Lunar Eclipse

A meme showing Lance Corporal Jack Jones, from the fictional Home Guard platoon portrayed in popular British sitcom 'Dad's Army' uttering his familiar catchphrase: "Don't Panic!" with a total eclipse of the Moon appearing crimson red in the background.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

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.

The Sentinel satellite program was designed to replace the older Earth observation missions, which have reached retirement or are nearing the end of their operational life span.  The satellite array will ensure a continuity of data, so that there are no gaps in ongoing studies.

Arecibo and the Great Silence – Where We Talk About a Parrot Named Alex

An aerial photograph showing the Arecibo Observatory telescope, with a picture of Alex at the forefront.  The dish reflector of the telescope is built into a valley in the landscape, and the feed antenna is suspended by cables above it. Since the reflector can't be moved, the telescope is steered to point at different regions of the sky by moving the feed antenna $ ($in bell shaped dome$ )$ along on a curving track. The dome shields the feed antenna from interfering radio signals. Collage: NaturPhilosophieArecibo – 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?

2016: Another Year in Cutting Edge Science

A photo-montage showing pictures of the recent scientific developments of the year 2016. From Major Tim Peake's extraordinary space adventure, to the discovery of the missing elements in the Periodic Table, and the gravitational wave detection from a merger of black holes far away in outer space...  Collage: NaturPhilosophieYou 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

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

You Wait Ages for a Chemical Element, and Then… BINGO!!

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?

Seeing the Light Fantastic – Particles, Waves and All

This seminal photograph shows, for the first time, light in all its beauty, simultaneously seen as a wave and as a particle.Light in All its Beauty

Taking a radically different experimental approach, EPFL scientists were able to take the first ever snapshot of light behaving simultaneously both as a wave AND as a stream of particles.  You need light to take a photograph.  But how do you take a photograph of light?

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?
