Summary of 32. Una revolución en el conocimiento: el microscopio

00:00:00 - 00:00:00

The video discusses the history of the microscope and how it has been used to reveal the cell and various microorganisms. It also discusses how the microscope has been helpful in developing knowledge in many scientific fields, such as biology, chemistry, and food science.

• 00:00:00 The history of the microscope is full of discoveries that have changed our understanding of the world around us. In 1590, Zacarías Jensen, son of a lens maker, constructed the first microscope, which consisted of two lenses. In 1610, Galileo Galilei invented the first microscope with a convex and concave lens, and described the geometric patterns seen in the eyes of bees. In 1665, Robert Hooke built the first microscope with two lenses and an objective. He used this instrument to observe tissues and insects very thin, thin cuts of metal. He called these structures "celular," which later was translated to "cell." In 1673, Anton van Leeuwenhoek designed and built many simple microscopes, all of which were composed of a lens and capable of magnifying images up to 200 times. He observed red blood cells, spiders, and mosquitoes, and what he found is now known as bacteria and viruses. Through the centuries, human curiosity has driven scientists to study diverse aspects of the world, including the microscopic world. Thanks to this curiosity, the microscope has been able to reveal the cell and various microorganisms. It has also been helpful in developing knowledge in many scientific fields, such as biology, chemistry, and food science
