What is the Smallest Object in the Universe? asks Rohan Alexander

What is the Smallest Object in the Universe?”   In 400BC, a Greek Philosopher questioned what would happen if you took a piece of matter, divided it and continued to divide it until you eventually came to a point where you could not divide it anymore. This man was called Democritus, and he was the […]

Grace Kendall debates – Matter vs Anti-Matter

Matter Vs Anti-matter: The Good and The Bad. Matter is everything. Matter is the substance of which everything is made. You; me; the thing you are reading this on, it’s all made from matter that was created after the Big Bang. So what is antimatter? Antimatter is the opposite of matter. The sub-atomic particles of […]

William Gallagher blogs about Strange Matter.

The Strangest Things in the Known (And Probably Unknown) Universe: Strange Matter What is Strange Matter? Well, the building blocks of Particles, (there are different building blocks of Particles like different quarks) they are called Quarks a force so strong that humans can’t pull them apart, because it would take an infinite amount of energy […]

Michael Leo blogs Acoustic Levitation

Acoustic Levitation When standing beside a loud speaker you can physically feel the sound; your clothes vibrate. This suggests that the sound emitted from the speaker has force. Sound waves consist of high- and low-pressure regions and it is this pressure fluctuation which results in the force exerted on your clothes. As an engineer, the […]

James Everitt explains Planck’s constant

How does Planck’s constant effect our everyday lives and how would things change if it had a different value? Planck’s constant is named after the German physicist Max Planck, who devised the idea for atoms to only be able to vibrate at set frequencies (quantised values). This is often credited as the first theory of […]

James Everitt blogs on UV/Visible Spectroscopy

UV/Visible spectroscopy relies on the interaction of molecules with electromagnetic radiation mainly in the ultra-violet and visible parts of the spectrum. This electromagnetic radiation according to quantum theory acts as both a particle and wave, known as wave-particle duality, it is this particle nature that allows electromagnetic radiation to interact with electrons and allow us […]

James Everitt blogs on electron movements behind UV/Visible spectroscopy

The electron movements behind UV/Visible spectroscopy by James Everitt. Electrons reside in orbitals around an atom. The most basic of these are the s and p orbital. Every electron shell in an atom contains one spherical shaped s-orbital which when it combines with another to form a bond forms what is known as a σ-bond […]

Thomas Watson blogs on Cherenkov Radiation

When a plane goes into super-sonic speeds a sonic boom is heard. The sound/pressure waves produced by the aircraft lag behind it (Fig 1.1), and as the waves are not faster than the super-sonic plane. The waves interfere with each other constructively, creating a large pressure wave which we hear as a distinctive boom. The […]

Thomas Watson blogs on asymmetry in the early universe

Asymmetry in the early universe One of the biggest un-solved problems in physics is why there is more matter than anti-matter. The mere fact that matter exists shows us that we do not know what happened in the early universe – in those first few seconds. It is theorised that in the early universe the […]
