Who is the "Father of Microscopy"?

Antony Van Leeuwenhoek is credited as the "Father of Microscopy" due to his significant contributions to microscopy.

What did Robert Hooke observe through a microscope in 1665?

Robert Hooke observed tiny pores or compartments in a piece of cork using a microscope in 1665. These were later named "cells".

What does the word "microscope" mean?

The word "microscope" is composed of two parts: "micro" meaning "tiny" and "scope" meaning "to view".

What is 1 nanometer (nm) equivalent to in millimeters?

1 nanometer (nm) is equivalent to 10-9 millimeters (mm).

Study Notes

Key Figures in Microscopy

  • Zacharias Janssen is credited with the invention of the microscope around 1590.
  • Robert Hooke, known as 'The father of microscopy,' observed cork cells in 1665 through a microscope lens.
  • Antony Van Leeuwenhoek contributed to microscopy by being the first to observe and document microscopic organisms and bacteria.

Microscopy Fundamentals

  • The term 'microscope' is derived from Greek words: 'mikros' meaning small and 'skopein' meaning to look or observe.
  • A scale equivalent of 1 nanometer (nm) is 0.000001 millimeters (mm).

Medical Laboratory Equipment

  • The most important machine in a medical lab is considered to be the microscope due to its critical role in diagnosis and research.

Optical Components of a Microscope

  • The optical components of a microscope primarily serve two functions: to magnify the specimen for better visibility and to resolve fine details to distinguish between closely arranged structures.
