Solar Cells – Applying the Photovoltaic Effect
Solar cells convert light energy into electrical energy using what is known as the photovoltaic effect, using the fact photons are absorbed by electrons when incident on a metal surface....
The particle at the end of the universe – by Sean Carroll
Based on the discovery of the Higgs particle, it starts by covering the fundamentals of particle physics. The first chapters explain key terminology and the brief history behind the subject,...
Feynman Diagrams
Feynman diagrams are used to graphically show particle interactions in a simple way. There are some basic rules which can be followed in order to learn how they are drawn....
What is ‘e’?
Euler's number, e, has a range of applications and is used primarily in exponential functions. The graph of y=ex has a gradient equal to the function, and is therefore the...
30 second quantum theory – by Brian Clegg
A brilliant summary of key concepts in quantum physics, this book covers 50 different topics. From the photoelectric effect right through to quantum computing and even teleportation, it covers a...
The Chemistry of Paint
Paint has a wide range of applications and the composition is essential to it having the desired properties. The colour comes from pigments, which often are made from transition metals....
