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.
Robert Hooke may have been the first to use this system. The three-lens system is the standard for light microscopes today. In the middle of the 17th century two important discoveries were made with the use of the microscope. Marcello Malpighi was one of the first great microscopists.
