Re: BE ALERT to short sharp stabbing pains in head!! Lucky, The reason they are suggesting an mri is for 2 reasons. The first being mris are alot more detailed than cat scans and can show things that cat scans cannot. Second they do it to cover their butts.
Quick Answer. Physicist Ernst Ruska and German engineer Max Knoll are credited with creating the first electron microscope in 1932. It permitted researchers greater magnification and resolution than traditional light microscopes.
1947 - Hungarian scientist Dennis Gabor first came up with the concept of a hologram while trying to improve the resolution of electron microscopes. He derived the name for holography, with holos being the Greek word for whole, and gramma which is the term for message.
