tom swift among the diamond makers

 so in my science, I was reading about microscopes. so there are electron microscopes and there are optic microscopes these use light and can make an object bigger at 1,000 times. and the electron microscope can shoot a thin beam of electrons right onto the thing. where it makes some of the electrons bounce back and a computer gathers this information. then make a 3d image on a computer monitor. but this is not that easy you must first create a vacuum by sucking all the air out of the place that you have the object and you must also freeze-dry the object in liquid nitrogen then you can use a microscope and electrons.
