It is called a nimrud lens. It is made out of rock and crystal. This was oftenly used to magnify the sun and start fires but it was also used as a magnifying glass.]]> 2022-01-05 17:51:49 UTC https://padlet.com/wpfeiffer1_1/82ks4oyhfdgm922u/wish/1977021772 wpfeiffer1_1 https://padlet.com/wpfeiffer1_1/82ks4oyhfdgm922u/wish/1977022599 This microscope was mostly used as a vision aid to help people read, write, etc. They called this a reading stone. It was usually a glass sphere or can looking shape like the one in the photo.]]> 2022-01-05 17:52:09 UTC https://padlet.com/wpfeiffer1_1/82ks4oyhfdgm922u/wish/1977022599 wpfeiffer1_1 https://padlet.com/wpfeiffer1_1/82ks4oyhfdgm922u/wish/1977023219 In 1284 the first eyeglasses were made. They used wood on the outside and the same glass as the reading stone as the lenses. Many people uses these to read or just to see things better and closer in.]]> 2022-01-05 17:52:27 UTC https://padlet.com/wpfeiffer1_1/82ks4oyhfdgm922u/wish/1977023219 wpfeiffer1_1 https://padlet.com/wpfeiffer1_1/82ks4oyhfdgm922u/wish/1977023813 The 1590 microscope is where they start to look more like microscopes. A father and son put many magnifiers in a tube and when they look through it it is very greatly zoomed. This was also a big step in making the telescope.]]> 2022-01-05 17:52:44 UTC https://padlet.com/wpfeiffer1_1/82ks4oyhfdgm922u/wish/1977023813 wpfeiffer1_1 https://padlet.com/wpfeiffer1_1/82ks4oyhfdgm922u/wish/1977024284 In 1625 microscopes looked somewhat like this. Only royal and wealthy people or scientists had these as they were not cheap at the time. In 1625 microscopes got their name and people all over the world started calling the microscopes.]]> 2022-01-05 17:52:54 UTC https://padlet.com/wpfeiffer1_1/82ks4oyhfdgm922u/wish/1977024284 wpfeiffer1_1 https://padlet.com/wpfeiffer1_1/82ks4oyhfdgm922u/wish/1977024652 In 1942 the first scanning electron microscope was born. It was made by Ernst Rubeska. It transmits a beam of electrons across the object to get a better look at it.]]> 2022-01-05 17:53:02 UTC https://padlet.com/wpfeiffer1_1/82ks4oyhfdgm922u/wish/1977024652 wpfeiffer1_1 https://padlet.com/wpfeiffer1_1/82ks4oyhfdgm922u/wish/1977025068 In 2010 some UCLA students used a microscope on a virus and could see its atoms. This was a huge step in microscope history as this is what microscopes are being used for today.]]> 2022-01-05 17:53:14 UTC https://padlet.com/wpfeiffer1_1/82ks4oyhfdgm922u/wish/1977025068
