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.

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.
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.

The Einstein Field Equations of General Relativity are vast and complex, but they can be written with deceptive simplicity.

Glasgow Science Festival 2013 begins today with a busy schedule of events for all ages!! Highlights include “Science Sunday”, a free event taking place at the University of Glasgow, Hunter Halls on June 9th between the times of 10:00 and 16:00.
The Open University has created a series of 6 short animated iTunes videos about the Philosophy behind Maths and Science.
Today, Thursday 14th March 2013. Only last year, the world of Particle Physics research was getting excited among rumours and speculation that the hunt for the Higgs boson at the Large Hadron Collider (LHC) was finally over, following the news that a Higgs-like particle had been identified in July.
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…

The Standard Model of Particle Physics is a theory about the electromagnetic, weak and strong nuclear interactions, developed throughout the mid-to-late 20th century, as a worldwide collaborative effort. Upon experimental confirmation of the existence of quarks, the theory is finalised in the mid-1970s. Ever since that time, further evidence of its validity have been provided by successive discoveries of the other predicted particles, such as the bottom quark (1977), the top quark (1995), the tau neutrino (2000) and even more recently, the Higgs boson (2012) to complete the whole set.
Today, Friday 15th February 2013. Russia’s Ural mountains. A fireball streaks through the clear morning sky. Loud bangs follow. A meteor crashes in Russia about 1,500 kilometres (930 miles) east of Moscow. As the shockwave blows out windows and rocks buildings, it injures at least 950 people, the BBC News reports. Most of those hurt from the Chelyabinsk region where the meteor fell, suffered cuts and bruises.
