A Close-Up Look At Microscopes

Tuesday, August 10th, 2010

The microscope is an important educational tool used in scientific research and education. It is used to produce a larger image of an object for projects ranging from medical discoveries to important educational training in schools across the nation. Microscopes use technology to allow humans to view objects as they could never be seen with the naked eye alone.

A conventional microscope was first developed during the last part of the 16th century, which lead the world of science toward a prospering future in the world of medicine and biology. In it’s earliest years, the microscope was primarily used as a recreational device and was found mainly in wealthier homes. It wasn’t long, however, before technology and research began to blend for a new discovery relating to blood circulation. In addition, advancements in the study of bacteria and diseases were among the discoveries that followed.

The majority of microscopes are called light microscopes, which uses a series of high powered magnifying lenses in order to bend light rays. Studies continued through the seventeenth and eighteenth centuries while, at the end of the nineteenth century, an even bigger development occurred. With the realization that electrons could be used as a light source in microscopes, scientists were provided with a never before seen resolution. The first electron microscope was unveiled approximately 75 years ago, which allowed for even smaller things to be researched and viewed. Among the advancements, atoms were finally visible for the first time and viruses could finally be identified with the powerful magnification and resolution of the electron microscope.

A microscope is an important tool and should be treated carefully. Proper care should be exercised when handling, or transporting, a microscope in order to avoid damage to the unit. Always carry the microscope with both hands and in the upright position. If you have a special tote or a box, either will work fine for transportation. When the microscope is in use, always make sure that it is placed on a flat surface and one that is not shaky. A sturdy table is the best placement for a microscope, but avoid placing it close to the edge where it could fall off to the side. After each use, follow the manufacturer’s instructions in proper cleanup of the unit, as well as any slides. If you do not plan to view the slide’s contents again, they should be cleaned in order to avoid interaction with future items that are placed on the slide for viewing.

While much emphasis is placed on scientific research and the technical aspects of microscopes, it’s important to remember that children can also benefit from the tool’s educational teachings. When you’re a child, it’s fun to collect a sample of anything and check it out under a microscope. Of course, microscopes begin as toys for smaller children and advance to larger, and more realistic models, as the child ages and is better able to understand the importance of the tool. If a child learns to be familiar with a microscope at a young age, he/she will be much more prepared for biology classes and the various parts and styles of microscopes.

Reading Books Online, A Blessing

If you are a book lover, then you will surely empathize with me when I say that shopping in book stores, especially the popular ones can be extremely harrowing. Gone are the days when readers had respect for literature, handled books with precaution and ensured that it remained spotless for years. An experience in a book store (and God save you if there is a book sale) is fraught with jostles, chaos and the experience of never being able to find the right book in the right section. The reverential Jane Austen’s may be found on the floor of the kids play section if not amidst Tom Sharp medley of slapstick humor.

To add to it all bookstores, have created special areas where prospective customers can review a book and then decide to purchase it. Started as a thoughtful concept, this reading section is a nightmare. Replete with kids, this area hardly gives you the impression of a place where one would like to take a few minutes to scan the latest bestseller. And the icing on the cake is the smudges and smears that these devils leave behind on the books that you consider precious.

Though feeling the book lends a lot of substance to the final decision of buying, any book lover would resort to the less invasive method of buying books on the Internet. If you are looking for an older book or one that is not for sale or has been approved for re writing, then finding it on the Internet should be easy. The only small hassle that one may face while doing so, is the need to scan the search engine results to finally lay hands on what you started to find. But thankfully that can be done sitting calmly in the privacy of your home.

To help you with the search process so that you don’t land up with irrelevant books which are non-bestsellers and science textbooks, here are a few websites which you may want to explore.

Bibliomania.com is a spirited, user friendly site that connoisseurs of literature shall find impressive. It has a collection of more than 2,000 books and is segmented by category.

LiteratureOnline.com gives you access to classics, The Bible and almost all Shakespearean works.
