Break a magnet into two pieces, and what do you obtain? What you get, unsurprisingly perhaps, are two new magnets – each one with two sides of opposite polarity. You don’t get a north half and a south half. Back to square one, it seems… Continue reading Magnetic “Monopole” Observed in Quantum System – The Lowdown on Electromagnetism
Ancients called mercury the “first matter” from which all other metals were formed. For centuries, the heavy metal was also used in medicine. Yet mercury is now in such disfavour that an international treaty exists to curb its use… Continue reading Mercury: Beautiful Poison
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. Continue reading http://www.roboearth.org/ – The Matrix is Everywhere…
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. Continue reading CSI Scotland: Murder by the Loch – Studying the Forensics…
Water. H2O. The chemical formula is simple. Two atoms of hydrogen H and one atom of oxygen O, held together by covalent bonds, are all it takes to make what is perhaps the most fundamental substance to life on Earth. Continue reading Water of Life
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?
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”?
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.
The Leidenfrost effect is most commonly seen in a kitchen Continue reading Heat Race Across a Maze with the Leidenfrost Effect
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.
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
The Open University has created a series of 6 short animated iTunes videos about the Philosophy behind Maths and Science. Continue reading 60-Second Adventures in Thought
Made of Atoms
IBM researchers currently hold the Guinness World Record for the ‘World Smallest Stop-Motion Film’ after creating a short film about a boy and his ball, by manipulating single atoms. Continue reading A Boy and His Atom
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…
