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…?

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…
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.
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…
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.
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.

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.
Continue reading Colour Perception and Retinal Neurons – Attempting to Map the Human BrainOver 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.
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.
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.
