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

A photograph taken at Loch Lomond. Image: NaturPhilosophieA 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?  Continue reading North by Northeast: The Trouble with the Earth’s Shifting Magnetic Field

Olivine – Squeezing Hydrogen from Stone and Capturing Carbon

A photograph showing a block of olivine gemstone.Olivine, A Common Earth Mineral

Olivine is a common green mineral, present in the Earth’s subsurface.  The mineral is also called ‘peridot’ and ‘chrysolite’ when mined as a semi-precious stone.

When exposed at the Earth’s surface, olivine weathers quickly.  The serpentine mineral that results is of increasing interest to scientists looking for a viable solution to clean the atmosphere from CO2Continue reading Olivine – Squeezing Hydrogen from Stone and Capturing Carbon

A photograph showing buddhist monks enjoying the scary thrills of a roller coaster ride. The Law of Conservation of Energy: Life's a roller coaster! - NaturPhilosophieWhat 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…  Continue reading The Law of Conservation of Energy: Life’s a Roller Coaster!

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

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

Heat Race Across a Maze with the Leidenfrost Effect

A photograph showing the Leidenfrost effect of liquid nitrogen in action. The experimenter's warm hand is seen plunged into a vat of liquid nitrogen, which spills over. Don't Try This At Home!

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
