# 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…

At the end of the 19th century, many people considered Physics as the foremost of sciences.  Perhaps chemical engineer Alfred Nobel (1833-1896) saw it in this way too, and that is why Physics was the first prize area which he did mention in his will. Continue reading Physics Nobel Prize 2013: Scotland’s Own Peter Higgs

# 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.

And since there is no accepted unified field theory, it remains an open line of research.  Canadian graduate student Timothy Blais decided to explore the idea and promote his findings in a way that really rocks…  ♫  Continue reading Strings + A Capella = “Bohemian Gravity”?

# The IPCC 2013 Report

The Intergovernmental Panel on Climate Change (IPCC) has just released its latest summary of the science behind human-caused climate change or, to use its catchy official title, the IPCC Working Group 1 Fifth Assessment Report Summary for Policy Makers – Climate Change 2013: The Physical Science Basis.

The document summary is 36 pages long.  The report includes 14 chapters and a dizzying amount of graphs, data and figures.  Here are just a few…  Continue reading IPCC 2013 Stockholm – Latest Findings on Climate Change

# A Familiar Sight in The Kitchen

The Leidenfrost effect is a phenomenon in which a liquid, brought in near contact with a mass significantly hotter than the liquid’s own boiling point, produces a thin vapour layer.  This insulating vapour layer keeps liquid from boiling rapidly.  Continue reading Heat Race Across a Maze with the Leidenfrost Effect

# Colour Perception – The Eye of the Beholder

Seeing the World in glorious colours is central to our lives.  Colours shape the way we behave.  They affect our mood and our perception.  They can influence the way we interact and respond to social and environmental stimuli, whether we are directly aware of it, or through subliminal awareness of our external world.  Again, it is one of those things that most people take for granted in everyday life.

Colour perception is all subjective.  Colours only exist when three components are present: a viewer, an object, and lightContinue reading Colour Perception and Retinal Neurons – Attempting to Map the Human Brain

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

# Physics meets Comic-Book Superheroes

The Physics of Superheroes is a popular science book by  James Kakalios, a Physics professor at the School of Physics and Astronomy of the University of Minnesota, and a long-time comic-book fan.  Continue reading “Pow”! “Bang”! The Physics of Superheroes

# 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.

# 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…  Continue reading The Moser Bottle Lamp: ‘Divine Light’

# 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.

If the calculation on vacuum instability holds, it would revive the old idea that the ‘Big Bang’ Universe we can observe today, is merely the latest version in a permanent cycle of events…  Continue reading Why the Universe may be Inherently Unstable

# Keeping It Relatively Simple

The Einstein Field Equations of General Relativity are vast and complex, but they can be written with deceptive simplicity.  Using modern notation, the field equations can be formulated as

$\boldsymbol G = \frac {- 8 \pi G}{c^4} \boldsymbol T$   Continue reading The Field Equations of General Relativity

# Scottish Downpours Tropical-Style

Near-tropical thunderous rain downpours have succeeded the balmy high temperatures that summer has brought to Glasgow of late.  Deep black skies.  Thunderbolts.  Lightning.  (♫ Very, very frightening!  Galileo Galileo… ♫)  Unusual conditions even for a very wet Scotland.   Continue reading Tropical Thunderstorms in Glasgow: The Tale of the Atmospheric River

# 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… Continue reading Secrets of the Bubble Chamber

# 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…

# 20th Century World View

The Standard Model of Particle Physics is a theory about the electromagnetic, weak and strong nuclear interactions, developed throughout the mid-to-late 20th century, as a worldwide collaborative effort.  Continue reading The Standard Model

# Historic Event in Astronomy

Today, Friday 15th February 2013.  Russia’s Ural mountains.  A fireball streaks through the clear morning sky.  Loud bangs follow.  A meteor crashes in Russia about 1,500 kilometres (930 miles) east of Moscow.   Continue reading Meteors over Russia

# Earth’s Electric Field

The Earth has an electric field.  On average, this field points vertically downwards and it has a magnitude of about 100 N C-1 (Newtons per Coulomb).  It exists because the Earth’s surface carries a negative charge of – 5 x 10C, while the upper atmosphere carries a compensating positive charge.  An average of 400,000 thunderstorms a day  Continue reading Lightning and the Earth’s Electric Field

# Record-Breaking Space Dive
