    Study Notes

    Ancient Greeks - The First True Scientists

    • Anaximenes was an associate of Anaximander.

    • He believed air was the most basic substance in nature.

    • He theorized when air thinned out it became fire.

    • He also believed when air thickened it became liquid and then solid.

    • Anaximenes attempted to explain that everything in nature is made up of a single substance.

    • Leucippus built upon the concepts of Anaximenes.

    • He believed all matter is composed of small units called “atoms”, and introduced the concept of atoms.

    • He is considered the Father of Atomic Theory.

    Louis Pasteur

    • Pasteur was a French chemist and microbiologist.
    • He destroyed the idea of spontaneous generation.
    • Made great advances in the study of bacteria and other organisms.
    • Pasteurization — Pasteurized milk.
    • Pasteurization is the process of heating a liquid to a certain temperature for a set period of time to kill harmful bacteria.

    Gregor Mendel

    • Mendel was an Augustinian monk who studied reproduction.
    • He was a devout Christian.
    • He is considered the Father of Modern Genetics.
    • Mendel created the study of genetics, which studies how traits are passed down through generations.

    Archimedes

    • Archimedes disliked science but enjoyed invention.
    • During this time, real science was actively discouraged.
    • He used mathematics to advance science.
    • He was one of the first scientists to demonstrate the close relationship between mathematics and science.
    • He is best known for his work with fluids and invented a method to determine the volume of an object.
    • This method led to the discovery of the relationship between mass and volume, which is known as density (density = mass/volume).
    • His famous phrase, "Eureka!" means "I have found it!"

    Alchemy

    • Alchemy passed for science during this time.
    • Alchemists believed they could find a way to transform lead into gold.
    • This practice involved mixing substances to create change.
    • This approach relied on trial and error and was based on observation and recording.
    • It contributed to the development of practical techniques and the discovery of new substances.

    The Renaissance: The “Golden Age” of Science

    • During this time period, science flourished.
    • New ideas and discoveries were made in astronomy, medicine, and other fields, and science began to be viewed as a valuable tool for understanding the natural world.

    Nicolaus Copernicus – Copernican System

    • Copernicus challenged the accepted view of the universe, which was based on the work of Ptolemy.
    • Ptolemy believed the Earth was the center of the universe. The Ptolemaic system places the Earth as the center of the Solar System, with the sun and other planets orbiting around it.
    • Copernicus proposed a heliocentric model, which placed the Sun as the center of the solar system.
    • He created the Copernican system, later disproven by Galileo's observation of Venus.

    Andreas Vesalius – Revolutionized Biology & Medicine

    • Vesalius was an anatomist who wrote a revolutionary book, “On the Fabric of the Human Body”, published in 1543.
    • The book was the first to illustrate all the internal structures of the human body.
    • He is considered the Father of Human Anatomy.

    Albert Einstein

    • Einstein is best known for developing the Theory of Relativity.
    • He explained the photoelectric effect which describes how light can knock electrons out of metal. This couldn't be explained by Newton's Laws of Motion.
    • He validated quantum mechanics, the idea that energy exists in discrete units called quanta.

    Niels Bohr

    • Bohr created the concept of the Bohr Model of an atom, which is based on solid mathematical principles.
    • The Bohr Model is a scientific model describing the structure of atoms.
    • He helped unveil the mysteries of the atom.
    • Bohr’s work helped establish quantum mechanics as the guiding principle in modern science.

    The Scientific Community

    • Science is moving forward and is more accepted in society.
    • Scientists are now more likely to share information and build on each other's work.
    • Science is now used to solve many problems that face society.
