The Day of the Chelyabinsk Asteroid

Just nine months ago, a massive asteroid blew up above the city of Chelyabinsk in Russia.  The explosion of the Chelyabinsk asteroid on Friday 15 February 2013 was the largest explosion on Earth since the one that occurred over the Tunguska region of Siberia in 1908.

The Law of Conservation of Energy: Life’s a Roller Coaster!

What is Energy?

And what does the Law of Conservation of Energy actually mean?  In science and Nature, the word ‘energy’ conjures up a wealth of images associated with speed of movement, activity and work.  Energy does appear in many guises.  Even matter is a form of energy.  Actually, everything in the Universe is nothing more than energy in one form or another…

Revisiting the Millikan Experiment – What’s in an Oil Drop?

A Historical Experiment

In 1909, physics pioneers Robert Millikan (1868-1953) and Harvey Fletcher (1884-1981) performed an experiment that would ultimately enable them to determine one of the most fundamental of all physical constants: the elementary electric charge, i.e. the electric charge of an individual electron – the constant e

Physics Nobel Prize 2013: Scotland’s Own Peter Higgs

Don't try this one: Professor Peter Higgs with a description of the Higgs model.
The Latest Physics Nobel Prize Laureate

The Physics Nobel Prize was awarded on 8 October 2013 to Edinburgh University-based scientist Peter Higgs for the theoretical discovery of a mechanism crucial to our understanding of the origin of everything…

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.

What do Physicists do anyway?

Air Apparent

Over 50,000 deaths each year in the UK are attributed to air pollution.  Physicist, entrepreneur and father Mark Richards is concerned about the environment and in particular the air pollution that we expose our children to.  He has developed a handy machine which can monitor air quality.  He wants people to see how bad air pollution is, so that we all think more carefully about our lifestyles and travel methods.

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.

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

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…
