Get Microscopes For Learning

By Carl Duvall


As an eight year old girl having very supportive parents, my mom and dad always encouraged whatever ambitions I had in mind and convinced me to become a scientist after I requested for a microscope. I received my microscope that Christmas. I was holding it like forever. I found myself in the world of the unseen, thinking that soon I could become a Nobel Peace Prize recipient for various scientific discoveries of new forms of life, new medicines, or anything that can benefit humankind.

I looked at everything I could get my hands on under that little microscope. Somewhat different, that winter produced various snowflakes. Ones that I've never seen before and I fell in love with its splendor. Delicately molded tiny crafts of art, each is a wonderful present created with its own distinction.

The microscope's mixture of glass lenses and light allows small invisible things to appear large to the naked eye.The writings of Seneca, Pliny the Elder, and Roman philosophers in the first century A. D. mention magnifiers, burning glasses (because holding them in the sun over a piece of parchment or cloth would set it on fire), and magnifying glasses. Formed like a lentil seed, these parts of magnifying glasses were termed as lenses.

It only used a hollow cylindrical object with a lens on one end that can magnify ten times the object's appearance and on the other end is a plate for the specimen. These were the first models of a microscope. Because they were so fond of watching fleas and other insects in it, they also termed the lenses as flea glasses.

The experimentation of several lenses in a tube led to the discovery of objects appearing enlarged in 1590 by Zaccharias Janssen and his son Hans. Other inventors extended their wisdom and ability in its development as the years went by. Galileo's development on the theory on lenses in 1609 gave way to a device that allows you to focus on the object under examination. Nevertheless, Anton Van Leeuwenhoek, a Dutch scientist, is known to have introduced microscopy. He was a novice at a dry goods store at first and utilized the magnifying glass to add up the threads in the textile. He became skillful with the lenses and curved ones that can amplify objects up to 270 diameters.He began to build microscopes and eventually made biological discoveries that made him famous. Microbiological discoveries such as bacteria, yeast plants, organisms in water and blood circulation in the capillaries is accredited to him. It must have been a breathtaking moment.Little improvements were made up until the 19th century when an American, Charles A. Spencer founded the manufacturing industry of fine - the best - optical equipment with magnifications up to 1250 diameters with regular light and 5000 with blue light.

Microscopes vary in shapes and sizes. You can buy one for your child to shift his interest on finding out specimens unseen by the naked eye. Other fields that use this as well are in the manufacturing and engineering sectors, scientific studies and medical field. Without a doubt and despite the size, it will still be intriguing to look through the lens.
