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.
The History of the microscope. An introduction to Microscopy. It is not quite certain who invented the microscope. Probably, spectacle makers in Middelburg, The Netherlands, invented both the compound microscope and the refracting telescope, between 1590 and 1610. The names most mentioned are those of Hans and Zacharias Janssen. The first well known users were van Leeuwenhoek and Hooke.
