Review Questions 1. What is a comparison microscope? What are the advantages of this microscope? A comparison microscope is a type of microscopes that is commonly used in a forensic laboratory. This microscope combines two microscopes into one unit‚ allowing the viewer to see what is under each of the lenses at the same time. This is a huge advantage because it allows you to compare evidence with a known sample because the two samples can be examined side by side. 2. What are the three substances

independently used the microscope to identify the cause of the bubonic plague. Compound microscopes—microscopes that use more than one lens—were invented around 1595. These first microscopes usually magnified objects only 20–30 times their original size. But as you will learn in the next few activities‚ even this level of magnification was enough to discover a world of new scientific ideas. By 1840‚ Italian physicist Giovanni Amici (a-MEE-chee) had invented the oil-immersion microscope which could magnify

Famous Canadian Entrepreneurs James Hillier and Albert Prebus (Electron Microscope) James Hillier‚ one of the entrepreneurs of the electron microscope‚ was born on August 22nd‚ 1915 in Brantford‚ Ontario. He attended the University of Toronto‚ where he received a PhD in 1941. After graduating‚ Hillier spent most of his career at the Radio Corporation of America (or RCA)‚ discovering the principle of stigmator‚ which is used to correct astigmatism in a microanalyser‚ while being the first person

In 1933 I was able to put into use electron microscope by myself which works much better then Light Microscope. 2 In 1928 Max Knoll and I worked together to make a microscope which we successfully discovered a Electron microscope which magnified object only up to 17 times bigger than actual size. In 1937 Canadian American scientist

The microscope is considered one of the most useful and important scientific inventions known to ’man’. The microscope was invented by Anton van Leeuwenhoek during the seventeenth century. Leeuwenhoek was not a scientist by profession. Initally he made a living selling clothes and buttons‚ but spent his spare time grinding lenses and constructing microscopes of remarkable quality‚ such as the light microscope. The light microscope could magnify cells‚ for instance in plants so you could see a clearer

How was the Microscope Invented? The microscope is a machine used to see tiny‚ small things such as germs and bacteria. These small creatures are not seen by us but can be seen by a microscope. The three subtopics that will be mentioned are: 1) Who invented the microscope? 2) Why was it invented and What are the different types of microscope. The prediction made was that the microscope was a very important part of life in the middle-ages. People had very serious sicknesses at that

the microscope. One of the first to use a microscope to observe microorganisms was Robert Hooke‚ the English biologist who observed algae and fungi in the 1660s. In the 1670s‚ “Anton van Leeuwenhoek‚ a Dutch merchant‚ constructed a number of simple microscopes and observed details of numerous forms of protozoa‚ fungi‚ and bacteria” (Introduction to Microscopes‚ n.d.). During the 1700s‚ microscopes were used to further explore on the microbial world‚ and by the late 1800s‚ the light microscope had
