Microscopes A Fascinating Look At The Micro World

Within every object there is a hidden world so tiny that we can't see it. Before the invention of the microscope people never realised that there was a tiny world beneath our feet. Back then even scientists didn't realise that each and every one of us was crawling with bacteria.

Most of these bacteria are perfectly harmless, in fact we need them to survive. With the invention of the microscope back in the 16th Century, scientists were able to peer into this world and unravel some of the great mysteries that they had been searching for years.

Not only did they see bacteria, they discovered that animals and plants are made of millions of tiny little cells. It was later when the first discovery of bacteria was noted.

Microscopes have changed our world and the world around us. Without them we would not have even discovered germs that we take for granted these days.

Electron Microscope

The Early microscopes consisted of a single magnifying lens. Compared to today where they use several lenses. These days microscopes can see the tiniest object that even a few years ago would have been impossible to see.

Electron microscopes are even more powerful. Instead of using light, they use a beam of electrons which are tiny particles that are seen in atoms. These are so powerful they can magnify objects many millions of times.

The fascinating thing about Electron microscopes is that scientists use them to see even the most basic structure of living cells, plastics and metals.

With Electron Microscopes objects must be cut into thin slices in order to see them. Too thick and the light won't be able to penetrate the object, therefore not giving a clear picture.

There is however, another microscope called a Scanning Electron Microscope which can scan the whole object. This can show the scientists the whole picture of the insect for example which will be useful for studying various parts of the body.

The Scanning Electron Microscope is so sensitive it can actually show individual atoms! These are so small that a line of 0.5 million atoms would only span the width of a human hair.

Inventing The Microscope.

Did you Know? Although the Romans used magnifying lenses about 2,000 years ago, the first real microscope appeared around the time of 1590.

It was built by Dutch spectacle makers Hans and Zacharias Janssen. Later, in 1663, English Scientist Robert Hooke studied insects and plants with his microscope. One of his first discoveries believe it or not was that cork was made up of tiny cells.

This caused great interest in the scientific world. Hence microscopes started making an impact on the world, and the science that we see today is based on those early studies and the first microscopes.

Optical Microscopes

The light or Optical microscope has two main lenses. These are called the objective and the eyepiece. For a higher definition they can add more lenses to give a clearer more defined picture of the object they are studying.

The Objectives as they are called can be anywhere between 10 times to 1,500 times normal size. This may not be as powerful as the Electron Microscope but is useful for home study uses.

I remember my first microscope. I was so excited that I literally ran down to the river to find objects to study. I came home with jam jars full of tiddler fish, bits of tree bark, ants, and even a lump of dirt that my dad insisted was too mucky to have in the house.

But I diligently cut it to pieces, placing each bit on the table and telling everyone that there was something 'crawly' inside! After my dad stopped shuddering, and my mother wanted to know exactly why my dad had bought me it, we discovered that it was a tiny beetle. I remember seeing the light fall on its carapace. Green and shiny. Amazing how our memories work. If I had the chance I would get another one and do it all again!

Microscopic World

Bacteria.

Bacteria are single celled and do not have a nucleus. They have one chromosome that carries DNA.

They are bigger than viruses but still can't be seen without a microscope. Bacteria have 3 classifications. In other words they come in three different shapes. Round, rodlike and spiral.

Bacteria are living creatures. They reproduce through a process called fission. Bacteria can be found in single cells or pairs and clusters.

Hydrothermal Worm

This rather scary looking creature (right) lives at the bottom of the Ocean. The photo was taken by Philippe Crassous using an Electron microscope.

It may look pretty horrendous but not to worry, its so tiny it cannot be seen by the naked eye. In fact its so small its similar in size to bacteria!

Using the Electron microscope, Philippe magnified it 525 times. Can you imagine being that small and looking like that?

I would think that it has to have some form of defence hence the teeth and horns. I am so glad its that small. Can you imagine seeing one of those staring at you, six foot tall? Erm well no!


Moth Head

The second photo shows one that is a bit more recognisable. Its simple a Moths Head. Fascinating to see it up close isn't it?

A Tiny World To Be Discovered.

The microscopic world is a fascinating one. Beneath our feet are miriad insects bacteria and viruses that we could never have seen in times past. With the invention of the microscope those worlds have been opened up to us.

What will we discover next? I am sure that there are many more tiny cells, insects and amazing micro lives that will be uncovered with the invention of the next generation of microscopes.

Hi, Nell. How are you today? I am hope you always healthy...amen. Wow...you have wonderful information about microscope. I agree with you that it can be the window of the micro world. We can't see a very small thing without microscope. So, I learn much related with microscope. I'll show this hub to my students. Good job, my friend. Voted up and take care!

Hi Nell,

If you're a biologist, and want to make a contribution to your field without traveling halfway around the world, head for the beach, collect a liter of fresh seawater, and start your research project, using an electron microscope.

The seawater will probably probably contain hundreds of bacteriophages that have never been studied before. These are viruses that eat bacteria. And they're more important than ever, in the light of multi-drug-resistant (MDR) bacteria.

Isolate a large sample of several thousand bacteriophages of the same type. Then expose subsamples of these beasties to each member of a 'library' of MDR bacteria: tuberculosis, MRSA, etc.

Of course, you'll need to do DNA analysis and other biochemical work after the gee-whiz preliminary study. And that's the expensive part. Which viral gene(s) code for the proteins that are responsible for the bacterial vulnerability that you've uncovered?

Voted up and beautiful.

Nell, I guessed bed bugs (rather than dust mites), still glad I vacuumed today, they are now living in my Dyson I s'pose. I thought the blade of grass was a caterpillar though. Some of those underwater critters are freaky aren't they? Great hub, loved the pictures.

I'm actually in the market for a good microscope. I had one as a boy, and I spent many fascinated hours peering at all sorts of things. I was particularly enthralled with a drop of pond water, and all the tiny critters that lived in it.

Perhaps you or Larry fields could recommend a good one!

Nell Rose 3 years ago from England Author

Hi Will, yes our Larry is a clever guy, I would love to go hiking with him, microscope in hand and a small fishing rod or net, now that would be a great afternoon! lol! yes the pond water is so full of life, we always took our fishing nets to the river or ponds, so many things to see, amazing life on a tiny level, thanks as always, nell

Hi Deb, I think we all had something similar as a child, we forget as we get older that its not just for the kids, I am going to get myself one after writing this, it caught my eye in a shop hence the hub, so when I get a bit of extra cash I am going to go exploring, lol! thanks as always, nell

It would be fun, Nell, to own and use an electron microscope. I would be so fascinated by the images I discovered, I would never get anything else done. If one is making a horror film, just blow up tremendously the images of the dust mites and hydrothermal worms, claim they are space aliens, and you will have a box office success.

Hi Will,

Sorry, I don't know enough to recommend one brand of microscope over another.

Several years ago, I remember visiting one of the vernal (seasonal) pools in Sacramento County. These have a microscopic Fairy Shrimp species that isn't found anywhere else in the world. There was also a lovingly maintained exhibit, including a microscope with a drop of that water on the slide. I actually got to see the beasties swimming around. What a hoot!

I would love to be able to look through one of those microscopes. I knew there was a microscopic world but some of those worms don't look too friendly. Even if we need them I don't like to think of what might be living in my bed. Nell, you did a great job with this hub. I sure learned a lot!

Really fascinating hub, Nell! What a world we live in! The used floss was unnerving and I'm going to have nightmares about it LOL. Some of the other photos looked like spectacular landscapes and the beasties -oh my! I'd get nothing done with one of these microscopes and of course, I really want one now. The termites looked kind of cute... a bit Disneyesque peering together into the hole :)
