Study Notes

The Dark Ages

The period was characterized by a slowdown in scientific progress.
The Roman Empire's decline impacted trade and communication, hindering scientific advancement.
The Roman Empire favored invention over scientific pursuit.
The printing press, invented by Johannes Gutenberg in 1436, revolutionized knowledge dissemination.
The printing press allowed for rapid and widespread sharing of information, accelerating the spread of knowledge, discoveries, and literacy in Renaissance Europe.
The printing press significantly contributed to the Protestant Reformation.

Medieval Microscopy

The Middle Ages saw the invention of the microscope due to a need to address the spread of diseases in urban areas.
Zacharias Janssen is credited with inventing the first compound microscope, featuring two lenses.

Medieval Telescopes

The Age of Exploration fueled the demand for nautical inventions, including the telescope.
The telescope, an optical instrument for observing distant objects, aided navigators.
The first telescope was created in the Netherlands in 1608.
Dutch lensmaker Hans Lippershey patented a device that could magnify objects three times.

Medieval Weapons

Widespread warfare during the Middle Ages spurred advancements in weaponry technology.
Northern European swordsmiths developed a method called pattern welding, combining iron or steel rods of varying hardness to create durable swords.

Robert Grosseteste

He was a bishop in the early 1200s A.D.
He proposed that understanding the laws governing the natural world could reveal God's designs.
He aimed to explain why things happened as they did.
He is considered the Father of the Scientific Method due to his rigorous use and explanation of the method.

The Modern Times (1500 to present)

Pasteurization

Louis Pasteur addressed the issue of food spoilage, particularly in dairy products.
He invented the process of pasteurization, which involves heating beverages to kill bacteria and then allowing them to cool.

Isaac Newton's Laws of Motion

The First Law of Motion, also known as the Law of Inertia, states that an object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.
The Second Law of Motion states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.
The Third Law of Motion states that for every action there is an equal and opposite reaction.

Robert Boyle

A contemporary of Newton, Boyle was a pioneer in modern chemistry.
He conducted experiments with gases, leading to Boyle's Law.

Anton van Leeuwenhoek

Known as the Father of Microscopy, he invented the first microscope capable of observing microorganisms.

The Enlightenment and the Industrial Revolution (1735 A.D.-1820 A.D.)

The Enlightenment was a period of intellectual and cultural change that emphasized reason, individualism, and scientific inquiry.
The Industrial Revolution was a period of rapid technological innovation that saw the introduction of new machines, factories, and power sources.

Antoine Lavoisier

A key figure in the Chemical Revolution, Lavoisier's work on combustion led to him being called the Father of Modern Chemistry.

The Rest of the Nineteenth Century (1820 A.D. to 1900)

Louis Pasteur

He disproved the theory of spontaneous generation.
He made significant advancements in the study of bacteria.
He demonstrated the role of yeast in fermentation, transforming glucose into ethanol.
He defined fermentation as respiration without air (anaerobic respiration).

James Clerk Maxwell

A prominent physicist, Maxwell developed mathematical equations that demonstrated Faraday's theory of electromagnetism.

James Joule

He determined that energy, like matter, cannot be created or destroyed, only converted from one form to another.
This principle is known as the Law of Thermodynamics.

The Modern Science (1900 A.D. to the present)

Max Planck

He proposed that energy exists in tiny packets called quanta.
This concept formed the basis for quantum mechanics.

Niels Bohr

Bohr created a model of the atom based on solid mathematics.
His model revealed many of the atom's mysteries.

Significant Discoveries of the 20th Century

1907: Radiometric dating revealed that the Earth is 2.2 billion years old.
1915: Einstein announced the general theory of relativity.
1915: Pellagra was identified as a dietary disease.
1924: Hubble discovered new galaxies.
1927: The Big Bang theory was proposed.
1928-1948: Alexander Fleming discovered penicillin.
1932: Chadwick discovered the neutron.
1938: Electroshock therapy was introduced.
1947: The transistor was invented.
1972-1985: CT scans and MRI were introduced.
1979: Cellular phones, radio, and telephone systems were introduced.
