Anyone ever use a microscope or ever have the urge to buy on?

What types of things can Crohnies do with one? i just feel like Exploring.. but only to benefit ourselves..

any idea?

Compound microscopes to be exact

It seems there is "very little" interest in microscopes here, debilitated ! smilewinkgrin
It so happens I have two microscopes. Why two ? Because I had a really naff one, which I tried to use for microbiology, and found that the important factor was not the magnifying power but the resolution. Resolution is the distance between two objects under the lens before they blur into one; so a resolution of say 1 nm is better than 2nm. Sadly, cheap microscopes only ever mention how much bigger the item will look, rather than how blurred it will be...so I bought another cheap microscope, and guess what... eyesshakehead yeah
You'll have guessed that I don't know a lot about microscopy. I assume a compound microscope is one that uses light, and has one eyepiece but several lenses. If you have one that has a binocular eyepiece I am so envious !
I do use mine occasionally, for looking at plant structures, fungi and insects. The lower magnification lenses do fine for this because the structures are larger than the limits of the resolution, and it is surprisingly easy to get good photographs - simply stick a camera on top of the eyepiece and press the button. What I would really like - no, love to do, is look at some microbes and cells under a good microscope, and see what Anton van Leevanhoek did... a world of miracles ! I live in hope that someday I will be able to afford an ex-school/laboratory microscope...
As far as Crohnies are concerned, I suppose we could in theory look at samples from apthous/PD ulcers and search for MAP or other bacteria. But beware - microbiology is a pretty intensive field in terms of getting clued up on what you are seeing...for anything more than casual sightseeing, I think you'd need to get some good textbooks.

I have one. I use it for some of the same reasons Snohare does. Mostly it helps me with gardening as I can get a good look at whats bugging me. Also , the older I get the, harder it is to tell a winged ant from a termite. I too have a cheep one because a good one is out of my price range. I'm sure there are tons of expensive ones gathering dust in school storage rooms. Nothing but the best from my tax dollors .
If we would read the secret history of our enemies,we would find in each mans life sorrow and suffering enough to disarm all hostility.
