If you look around and have a closer look at your surroundings, you will find the world is filled with many things like people, trees, birds, cars, and many more. If you watch the night sky, you will see stars, moons, and even the distant planets. Maybe these objects rest millions of miles away from you, but aren’t these things amazing for you? You can see them with your very own eyes.
However, what about the things that you can’t see with your eyes? Yes, we are talking about the intangible things. The things that we mentioned earlier are tangible but there is much more than what you can see through the eyes such as germs dust mites, bacteria and so on. These things are all around us and they are invisible to our naked eyes.
In terms of science, we called these things – ‘Microscopic Objects’ because they can’t be seen without microscopes or magnifying glass. In addition, our eyes have limitations as we are not able to see small objects without these devices. The term – ‘Magnification’ refers to making something big without changing its actual physical size. You will see that magnifying tools utilizes a special kind of lens for bending light at an angle, which will increase the size of the image that we will see through our eyes. As a result, you can see the tiniest of objects easily. The more the lens is increased, the better you can see the objects.
According to experts, with our regular vision, we can see objects small as about 0.1 millimeters. And this is without the help of any tools. The smallest things you can see through your eyes are human hair and lice (both of these things can be seen with the naked eye and under a microscope).
However, if you use powerful microscopes, we can see things that incredibly small. Even these things that are not possible to see through the naked eye can be seen with microscopes. A microscope will help you see objects small as 0.001 mm or one micrometer. The ‘microsphere nanoscope,’ a recent invention will allow us to see things up to 20 times smaller. This device is a combination of a standard microscope and a complex device, known as the transparent microsphere. The experts believe this powerful tool will help them to see through human cells. Even they will be able to examine live viruses in a detailed manner.
In the future, more accurate tools and devices will be developed to see even smaller things. This is the belief of scientists because there is no limit to how small an object can be. Therefore, scientists are thrilled to have the possibilities of this new tool that will be opened up in the future time.
