The Rosetta Spacecraft

January 20, 2014.  500 million miles from Earth.  09:59:58…  09:59:59…  10:00:00 GMT.  After spending two and a half years into deep-space hibernation, Rosetta awakes

Strings + A Capella = “Bohemian Gravity”?

Bohemian Gravity: "Any way you quantize, you encounter infinity."
Describing The World Dynamics So Far

According to the current understanding of Physics, there is as yet no uniform field theory.  No all-encompassing well-rounded theory that would enable all the known fundamental forces and elementary particles to fit neatly into one simple model, and to be expressed in terms of a single field.

The Art and Science of Music Acoustics – From the Humble Flute to the Mighty Didgeridoo (Featuring Tarzan…)

Fundamentals of Music Acoustics

Any signal that may be represented as an amplitude varying over time has a corresponding frequency spectrum.  This applies to concepts (and natural phenomena) that most human beings encounter daily, without giving them a second thought.  Such as visible light (and colour perception), radio/TV channels, wireless communications…  Even the regular rotation of the Earth.  Even the sound of music…

The Moser Bottle Lamp: ‘Divine Light’

A close-up photograph of Alfredo Moser in the light of the bottle lamp - his makeshift invention.
Sun Light in a Bottle

“God gave the Sun to everyone”, Alfredo Moser states modestly.  And Moser gave his light to everyone.  Over the last couple of years, Moser’s ingenious innovation has spread throughout the World, bringing the bottle lamps to locations from Brazil to the Philippines and Bangladesh.  By early next year, it is estimated that one million homes will have benefited from his simple idea…

Exploring Vacuum Instability

Scientists are currently exploring the concept of vacuum instability.  What does this mean?  Well, they believe there is a chance that…  Billions of years from now, a new universe could open up into the present one and replace it.  It all depends on some very precise numbers related to the Higgs boson particle that researchers are currently trying to pin down.

The Field Equations of General Relativity

An artist's impression of the Earth's gravity field as described in Einstein's General Relativity.

Keeping It Relatively Simple

The Einstein Field Equations of General Relativity are vast and complex, but they can be written with deceptive simplicity.

Secrets of the Bubble Chamber

A picture collage showing the Gargamelle bubble chamber and the Smurfs archvillain sorcerer, Gargamelle.
What Do Gargamelle and Picasso Have in Common?

Nope.  Nothing to do with the arch-nemesis of the Smurfs or with an avant-garde artistic masterpiece, unlike the top picture appears to suggest…  Actually, the Gargamelle on the left is at CERN and takes its name after the giantess in the works of satirist François Rabelais: she was Gargantua’s mother!  The Gargamelle is a historical ‘bubble chamber’ detector however…

Once in a Blue Moon…

One of a Rare Status Update

Apparently, the phrase “once in a blue moon”, in the sense of something that occurs very rarely, dates back to 1824.  I will check this out as soon as I have time…

12 Short Videos about the Physics of the Cosmos

The Open University has teamed up with “geek chic” comedian David Mitchell to release a series of 12 short animated YouTube videos about the Physics of the Cosmos: “60-Second Adventures in Astronomy”.  A real treat.  And it’s educational!  If you have only 60 seconds, you can now learn everything we know about matter, energy, life, the Universe and everything…

Rainbows: Technicolor Symphonies in the Sky

Rainbows are one of Nature’s most gorgeous optical spectacles to behold, brightening up clouded skies with an ephemeral palette of colours when the light falls just right…
