Finally, it outlines best practices for using and caring for compound microscopes.
Microscope types and use
This document provides an introduction to different types of microscopes. It discusses light microscopes which use lenses to magnify objects from 40x to 400x. Stereoscopes allow binocular viewing from 10x to 20x magnification and create a 3D view. Scanning electron microscopes use electrons instead of light to magnify up to 2 million times but cannot view living specimens. Transmission electron microscopes also use electrons passed through very thin specimens to see inside cells. Different illumination techniques make some specimen parts more distinct. Total magnification is calculated from the objective and eyepiece lenses. Online resources for virtual microscopes are also provided.
Cell Theory - Early History
Anton van Leeuwenhoek and Robert Hooke were early pioneers in microscopy who made important discoveries about cells. Matthias Schleiden, Theodor Schwann, and Rudolph Virchow contributed to the development of the Cell Theory, which states that all living things are made of cells, cells are the basic units of structure and function, and cells only come from preexisting cells. Their combined work in microscopy and cell observation laid the foundation for understanding biology at the cellular level.
Different types of microscopes
This document provides information on different types of microscopy techniques including bright field, dark field, phase contrast, and polarized light microscopy. It begins with explaining the basics of light and microscopy. It then describes each technique in more detail, including their principles, applications, advantages, and how they are set up optically. Bright field microscopy uses illumination and forms a dark image on a bright background. Dark field uses oblique illumination to see small particles as bright objects on a dark background. Phase contrast converts phase differences into contrast changes to see transparent specimens. Polarized light microscopy uses polarized filters to reveal structural details not otherwise seen.
Microscopy
The microscope has evolved a lot from the time of Leeuwenhoek. This presentation gives a brief overview about the types of microscope their principle of function and application.
compound microscope (basic)
The document discusses compound light microscopes. It explains that compound microscopes use multiple lenses to magnify specimens and have different light sources - some use mirrors to focus sunlight while others use illuminators. It then describes the main parts of a compound microscope - the eyepiece, body tube, objectives, stage, arm, base, illuminator, nosepiece, condenser, and diaphragm. Finally, it discusses how light travels through the microscope and some common uses of compound microscopes, such as pathology, forensics, education, and biology.
History of the Microscope
The microscope was invented in 1595 by Hans and Zacharias Janssen in Holland. It was later perfected in the 17th century by Robert Hooke in England and Anton van Leeuwenhoek in the Netherlands. Van Leeuwenhoek was the first to observe bacteria, yeast, and single-celled organisms using early compound microscopes. Industrialization in the 18th-19th centuries led to standardized microscope parts and mass production, increasing access and new discoveries. Electron microscopes developed in the 1930s allow for higher magnifications over light microscopes.

Microscope history
- Ancient Greeks and Romans discovered that glass lenses could magnify objects and observed magnification effects. The first microscopes in the late 16th century used single lenses but had low magnification around 9x.
- In the late 17th century, Antonie van Leeuwenhoek developed techniques to grind glass into superior small lenses and was able to achieve 270x magnification, greatly exceeding other microscopes of the time. Using his microscope, he discovered bacteria, yeast, and blood cells.
- Compound microscopes using multiple lenses were developed in the 17th century to further increase magnification over single lens microscopes. Major problems of aberration were solved over the centuries, reaching a theoretical resolution limit around 1800. Modern microscopes

Optics
The document provides a history of the invention and development of telescopes from the early 17th century to modern times. It discusses how Hans Lippershey is generally credited with inventing the refracting telescope in 1608, though others may have contributed. Galileo improved upon the design and was the first to use telescopes to make astronomical observations. Later, James Gregory designed the first reflecting telescope in 1663, and Isaac Newton built the first practical reflecting telescope. Over time, refracting and reflecting telescope designs continued to be improved and developed. Modern telescopes include radio telescopes and space-based telescopes like Hubble.

The microscope
The microscope allows us to see objects too small for the naked eye. Romans discovered the magnifying properties of lenses in the 1st century AD. In the 1590s, Dutch lensmakers invented the compound microscope by using multiple lenses. Galileo and Leeuwenhoek later improved microscope design and were the first to observe bacteria and blood cells. Today's advanced microscopes have led to discoveries in medicine, forensics, and other fields by enabling observation at the atomic level.
Microscopy
Robert Hooke invented the early light microscope in the 1600s, which allowed him to discover cells when examining cork. Microscopes have since improved, with higher resolutions and magnifications. In the past, microscopes were handmade and valuable, sometimes decorated with gold. Today, scientists can see individual atoms using electron microscopes, though light microscopes remain useful too. A variety of techniques exist for microscope observation, depending on the type of microscope and observation needed.
History of the Microscope.ppt
The document provides a history of the microscope, beginning with its invention in the 1590s by Hans and Zaccharius Janssen who created the first compound microscope. It then discusses key figures like Galileo, who improved on the compound microscope, and Anton van Leeuwenhoek, a 17th century Dutch tradesman who greatly advanced lens grinding techniques and was the first to observe bacteria and other microorganisms using his simple microscopes. The document outlines Leeuwenhoek's important contributions through detailed observations and illustrations that he shared with the Royal Society of London, including his famous observation of "animalcules" in plaque and pond water.
Lesson 2 discovering the cell 2015
1) In the 16th and 17th centuries, early microscopists like Janssen, Leewenhoek, and Hooke began observing and describing cells using microscopes.
2) Hooke was the first to use the term "cell" to describe the basic units that make up living things.
3) In the early 19th century, scientists in Germany developed the cell theory, which stated that all living things are made of one or more cells, cells are the basic unit of life, new cells are produced from existing cells, and cells can function independently.
4) The development of the electron microscope in the 1930s allowed scientists to view cells and their internal structures in much greater detail.

How to Manage Reception Report in Odoo 17

Because multiple clients may inquire about the same product at the same time, after purchasing those products, customers must be assigned to them. Odoo has a tool called Reception Report that can be used to complete this assignment. By enabling this, a reception report comes automatically after confirming a receipt, from which we can assign products to orders.
