What was Robert brown looking at through a microscope when he found evidence of the 1827 scientific concept names in his honor?
Robert Brown (1773-1858) was a scottish botanist who is largely remembered for the contributions to botany that he made by using the microscope. In 1827 while looking under a microscope while looking at grains of pollen from Clarkia Puchella he noticed that minute particles ejected from the pollen was executing jittery motions. He observed the same phenomenon in an inorganic sample so he was able to conclude that this motion was not related to life. This motion was named Brownian Motion after Mr. Brown.
Why should you never lower the body tube of a microscope while looking through the eyepiece?
As I learned the hard way if you are adjusting the body of the scope while looking through the lens it is very easy to exceed the pressure threshold of a plate and crack it, destroying your sample and all your hard work. Move the slide and scope into place then look through the lens for fine adjustments.
What is the difference between ordinary microscope and electron microscope?
Magnification and resolution is in light microscope is about 500x and 0.2micro metres respectively than human eye.In e.microscope magnification is about 200,000x and resolution is 0.0005micro metres. You cannot observe live specimen through electron microscope. Lenses in light microscope are glass while e.microscope use magnetic lenses. E.microscope is relatively very larger than light microscope. You need special knowledge to handle electron microscope. You can observe through naked eye in e.microscope. A beam of electrons is sent through specimen in e.microscope.In light microscope a beam of light is sent. Electron microscope is very complex relative to light microscope.

What are the 2 knobs on a microscope called?
There are two adjustment knobs (coarse and fine) on a microscope so you can move the stage at two different speeds. The coarse moves a lot per revolution, while the fine adjustment knob moves the stage at such small increments that it is nearly impossible to notice when looking from the side. The coarse adjustment knob should be used to get the stage closer to the lens only while you are looking at the microscope from the side. The fine adjustment knob can be used when you are looking into the microscope because there is a much lower chance of running the stage into the lens and breaking it.
