Viewing techniques for urban stargazing
By: Mo Bruce
Urban stargazing has always been a bit of a compromise, due to the city light pollution wiping out the stars in the night sky. This doesn’t mean that you can’t enjoy observing astronomical objects from within the boundaries of a city environment. There...

The valence bond theory is a quantum mechanics theory that, like the molecular orbitals theory, tries to explain the chemical bonding between atoms. Each of these theories have different perspectives on how the bond forms. The valence bond theory is a theory which assumes that...

Stargazing in the urban environment is not always the easiest thing to do. Light pollution can wipe out all but the brightest objects in the heavens, while manoeuvring your telescope to the ideal viewing area outside the city, can prove a bit off putting to...
The history and future of the universe
By: Ray Burke
The past and future universe October 2010 – the TV science programme ‘Horizon’, examined the theories of what came before the Big Bang by several prominent physicists. The notion that anything could come before the Big Bang has been dismissed by many who cannot...

Molecular orbital theory is a theoretical method in chemistry that tries to give an explanation to the chemical bond in terms of molecular orbitals formation that are formed by the addition and subtraction of two atomic orbital functions. This method tries to rationalize the formation...

The constellations are the star groups we see in the night sky, and they were given their names many thousnads of years ago. The stylisation of the star groups into patterns bearing names such as Orion the Hunter, Leo, or simply the Scorpion, provides us...
