Silent Sun

Why 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…

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

A Rambling Geomagnetic Pole

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?

http://www.roboearth.org/ – The Matrix is Everywhere…

What is RoboEarth?

A world wide web for robots to learn from each other and share information is being unveiled for the first time.  The eventual aim of the system is that both robots and humans will be able to upload information to the cloud-based database, which would act as a kind of common brain for machines.

CSI Scotland: Murder by the Loch – Studying the Forensics…

A colour drawing of Ross Priory - an early 19th-century country house, located west of Gartocharn, West Dunbartonshire, on the south shore of Loch Lomond, Scotland. The scene of the crime? Forensic science and murder meet by the Loch.
Can you Solve the Murder by the Loch?

Well, you can try…  I love a gothic mystery, don’t you?  😉

You have six weeks to do it – and a staged murder at Strathclyde University’s Ross Priory house – using the techniques of forensic science.  Starting NOW.

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

A droplet of oil just falling into a little yellow pool.
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

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.

Tropical Thunderstorms in Glasgow: The Tale of the Atmospheric River

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.

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…

Lightning and the Earth’s Electric Field

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 sustain a relatively constant electric field.

Let There Be Light…

Fiat Lux…

Light.  Most of us take it for granted during the day.  And at night, we have learned to domesticate it.  Light, the natural agent that stimulates our sense of sight and makes things around us visible.
