Is light a particle or a wave?

One of the first people to have a documented position on this was Pythagoras. Unbeknownst to a lot of people besides from giving us the rule about right angle triangles that everybody learns about at secondary school probably the world over he also believed that everything in the world can be explained with mathematics. It […]

What is antimatter?

Matter or ‘stuff’ we encounter in our day to day experience such as gases, liquids or gases is composed in different arrangements of atoms. Inside these atoms are protons, neutrons and electrons. The protons and neutrons are made of smaller subatomic particles called quarks. All these building blocks: atoms, protons, neutrons, electrons and quarks can […]

Reality is an illusion!

The atoms that our bodies are made from are composed of a tiny dense and heavy nucleus that is surrounded by shells of electrons if you are a chemist or probability density clouds if you are a physicist. It is widely understood that most of the atom is in fact empty space. The heavy dense […]

One of my greatest pleasures is catching a beautiful sunrise or sunset. In the Autumn and Winter months when the nights start to draw in earlier some of the sunsets on my drive home are simply breath-taking! As discussed in a previous blog explaining why the sky is blue.

How does a plasma ball work?

Most people remember being told at school that there are only three states of matter; solids, liquids, and gases. They might be surprised to hear that there is a fourth state of matter called Plasma and think that the list ends there. This isn’t true and there are several more and the number stated varies […]

Why is the sky blue?

White light is composed of of a continuous spectrum of colours. You will remember Richard Of York Gave Battle In Vain. A useful way to learn Newton’s seven colours in order. You could argue that as it is a continous spectrum there are many more colours than seven. Newton chose seven as apparently he liked […]

What is the fate of the universe?

Big Crunch, Big Rip or Big Freeze? The Big Rip hypothesizes that the rapid increase in the universe’s expansion powered by dark energy will eventually create greater forces than gravity. This would essentially rip apart all matter in the universe such as the sun, the Earth and even black holes! The Big Crunch hypothesizes that […]
