Just when you had high hopes of getting your hands on the latest gizmos and trendy gadgets in time for Christmas… and Boom! You’re being given a comet! Not just any comet. Comet ISON (C/2012 S1). It’s 4.6 billion years old! And it will pass within 40,000,000 miles of Earth. Continue reading Making Plans on the Comet – C/2012 S1 IS ON!!
Aawww!! What? Not what you were expecting? What are you like… Anyway, it made you look! 😉
This great sex show, the greatest sex show on Earth, happens every year, around about now, in November. When the tides are just right and the Moon is full, the Coral Reef literally erupts! Continue reading November’s Greatest Sex Show on Earth
Have you even heard his name before? Frederick Sanger?
Dr Frederick Sanger, the British biochemist who is considered to be the “Father of Genomics“, died yesterday, aged 95.
Typhoon Haiyan was a huge weather system. If you haven’t heard about the devastation caused by Typhoon Haiyan in the Philippines by now, then you probably don’t care… Continue reading In the Eye of Super Typhoon Haiyan
Just nine months ago, a massive asteroid blew up above the city of Chelyabinsk in Russia. The explosion created by the Chelyabinsk asteroid on Friday 15 February 2013 was the Continue reading Chelyabinsk Asteroid: Nine Months After The Russian Meteor Impact
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!
The Humble Hydrogen Atom
Back in May 2013, scientists announced that they had managed to capture a photo of an electron’s whizzing orbit within a hydrogen atom, using a unique new technology of ‘quantum’ microscopy. Ladies and gentlemen, let’s take a short trip into the infinitesimally small! Here is the first photograph of a hydrogen atom! Continue reading At the Heart of the Hydrogen Atom…
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. Continue reading Revisiting the Millikan Experiment – What’s in an Oil Drop?
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
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
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 light. Continue reading Colour Perception and Retinal Neurons – Attempting to Map the Human Brain
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…)
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
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.
“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
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
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

Apparently, the phrase “once in a blue moon”, in the sense of something that occurs very rarely, dates back to 1824. I will check this out as soon as I have time… Continue reading Once in a Blue Moon…
