Quantum Cryptography (a background)

In this article I hope to illustrate some of the ideas behind the strange topic of Quantum Cryptography, though I won’t be discussing cryptography itself, that comes later – just the necessary physics. First we must consider the nature of light (this can be generalised to any particle once we get all quantum mechanical, but let’s [...]

Large Hadron Collider

The LHC at Cern will be switched on today, though there won’t be collisions for a little while. The LHC will collide Hadrons (obviously) at high speeds. Hadrons are particles which contain quarks. Everyday examples are Protons and Neutrons. The LHC can only accelerate charged particles and so it’ll collide protons. The high energy collisions will [...]

How to Destroy the Earth

An amusing little documentary about ‘How to Destroy the Earth’ – and it’s all factually correct (if silly). One thing, with an anti-mountain, crashing it into the Earth from space isn’t going to be a major factor – just being on Earth will do it. Admittedly though, the anti-mountain would have to be manufactured away [...]
