It’s a Higgs!

Hunting For The God Particle

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 Standard Model

... but what is a Higgs Boson?

20th Century World View

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.

Meteors over Russia

Historic Event in Astronomy

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.

How to Weigh a Supermassive Black Hole?

Black Holes

Black holes are known to exist at the centres of most galaxies, including our own Milky Way.  The masses of those black holes are correlated to many of the properties of their host galaxies, which strongly suggests that galaxies and black holes evolve together.  Measuring their masses and comparing them in a variety of different galaxies is crucial to the understanding of the interactions between the two components.

Let There Be Light…

Fiat Lux…

Light.  Most of us take it for granted during the day.  And at night, we have learned to domesticate it.  Light, the natural agent that stimulates our sense of sight and makes things around us visible.

Astronomical Beginnings

Early astronomers already make the distinction between stars and planets, as the former remain relatively fixed for centuries, while the latter wander an appreciable amount in a comparatively short time.  But that’s not all!
