While experimenting they noticed that the things they viewed in front were enlarged."Creating both the telescope and the forerunner of the compound microscope."]]> 2022-01-06 12:29:08 UTC https://padlet.com/sbose9_1/pwlvwcvbchumqpsw/wish/1978475517 sbose9_1 https://padlet.com/sbose9_1/pwlvwcvbchumqpsw/wish/1978478219 A simple microscope was built by Anton Van Leeuwenhoek that had only one lense to observe blood, yeast, insects, and other tiny objects. He was also the first to describe bacteria. ]]> 2022-01-06 12:31:17 UTC https://padlet.com/sbose9_1/pwlvwcvbchumqpsw/wish/1978478219 sbose9_1 https://padlet.com/sbose9_1/pwlvwcvbchumqpsw/wish/1978484559 Joseph Jackson Lister reduced spherical aberration. He did this by showing that many weak lenses put together at specific distances gave a good magnification without it blurring the image. This was known as the prototype for the compound microscope.]]> 2022-01-06 12:36:09 UTC https://padlet.com/sbose9_1/pwlvwcvbchumqpsw/wish/1978484559 sbose9_1 https://padlet.com/sbose9_1/pwlvwcvbchumqpsw/wish/1978493405 The ultramicroscope was made by Richard Zsigmondy. "It was capable of studying objects below the wavelength of light.

This microscope was able to study colorless and transparent biological materials. He won the 1953 Nobel Prize in the category physics. ]]> 2022-01-06 12:44:19 UTC https://padlet.com/sbose9_1/pwlvwcvbchumqpsw/wish/1978499239 sbose9_1 https://padlet.com/sbose9_1/pwlvwcvbchumqpsw/wish/1978503187 Gerd Binning and Heinrich Rohrer invented one of the strongest microscopes known as the scanning tunneling microscope. It gives three dimensional images down to the atomic level of objects. For this he won a Physics Nobel Prize in 1986.]]> 2022-01-06 12:46:40 UTC https://padlet.com/sbose9_1/pwlvwcvbchumqpsw/wish/1978503187 sbose9_1 https://padlet.com/sbose9_1/pwlvwcvbchumqpsw/wish/1978509467 The electron microscope was co-invented by Ernst Ruska in which he won a Physics Nobel Prize in 1986. Electron microscopes can view things that are up to as small as an atom. An electron microscope uses electrons rather than light to observe an object. Electrons are sped up in a vacuum until their wavelength is very short—only 0.00001 that of white light.]]> 2022-01-06 12:50:39 UTC https://padlet.com/sbose9_1/pwlvwcvbchumqpsw/wish/1978509467
