Scotland’s Quiet Revolutions

It seems quiet at first, and even dull.  Not much happening…  Dreich, as one might say!  Sad.  Grim.  Bleak.  Not much to do…  Not much to see here…  Just sheep…  But wait!!  Look closer!  Is that Dolly in this field?  Now, that’s interesting!  Oh, Aye, we’re in Scotland!  It changes EVERYTHING…  Continue reading Scotland’s Quiet Revolutions – One Nation with Sovereign Achievements… and a Pure Dead Brilliant Future!

We Glimpse at the Body Electric – An Introduction to the Physics of the Human Nervous System

An artist's impression of the human nervous system at work.The Human Nervous System: 100 Plus Billion Cells

The human nervous system contains roughly 100 billion nerve cells.  Worth pausing for an instant… and read it again.  That’s right, 100 billions!  To give an idea of the scale, the Milky Way, our own galaxy, contains roughly 100 billion stars.  And although human beings are way smaller than galaxies, we begin to appreciate how each one of us is as complex, as mysterious, and as magnificent in its own right, as any large astronomical entity in the physical Universe Continue reading We Glimpse at the Body Electric – An Introduction to the Physics of the Human Nervous System

Van der Waals and the Gecko

A photographic collage showing a black and white portrait of Van der Waals and a gecko climbing on the outside of a corrugated glass panel.The Sticky Physics of Van der Waals Forces

Geckos are amazing creatures.  They scamper up walls, scuttle along ceilings and hang upside down on polished glass surfaces.  However, the secret of their amazing climbing ability remained a mystery until relatively recently.  The secret lies in weak intermolecular forces, described by Van der Waals in 1873.

The Enduring Mystery of Earthquake Lights – What Makes a Miracle?

A photograph showing an earthquake light - a rainbow cloud, taken in May 2008, in the region of Sichuan, China.Earthquake Lights in the Sky

Mysterious flashes of light and clear-sky lightning, blue flames?  Glowing orbs and fireballs?  Will-o’-the-wisps?  Stand-alone rainbow clouds and light pillars?  How could this be…?

Scientists in the United States now say that earthquake lightning flashes appearing to precede earthquakes, are likely to be sparked by movements within the ground below.  This phenomenon could be used to trigger alarms and help warn millions of an impending danger…

Silent Sun

A photograph of the Sun's full disk. Image: NASAWhy has the Sun been so quiet?

The Sun ought be awash with activity right now.  But space scientists are baffled…  The Sun has reached its solar maximum: the point in its 11-year cycle where activity is at a peak.  Yet it has hit a lull.  And to see when the Sun was this inactive last… you’ve got to go back about 100 years…  Continue reading Silent Sun

North by Northeast: The Trouble with the Earth’s Shifting Magnetic Field

Magnetic North made an unusual and historic shift.  For the first time in more than 220 years of map making, Ordnance Survey has noted that North lies East, and not West, of Grid north for parts of Southern Britain.  But how does this shift in magnetic field affect map reading in Scotland’s hills?  Continue reading North by Northeast: The Trouble with the Earth’s Shifting Magnetic Field

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…

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.

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.

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

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.

Why the Universe may be Inherently Unstable

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
