The magnetic resonance imaging (MRI) scanner was first built in New York in 1977. It has since been vital to the advancement of neuroscience and understanding disorders in the brain. The scanner itself is an enormous magnet that produces a magnetic field which is over 10,000 times stronger than that of the Earth. This fieldContinue reading “Magnetic Resonance Imaging: Spinning Protons”

Lasers: Well-Behaved Light
The theoretical foundations of the laser were put forward by Einstein in 1917 but it wasn’t until the 1940s that physicists found applications for his ideas. Nowadays, lasers are responsible for a multi-billion pound industry which includes correcting vision defects through laser eye surgery and sending data across the globe via optical communication. The operationContinue reading “Lasers: Well-Behaved Light”
