History of Medicine and Chemistry

Emergence of Medicine and Chemistry

• The 16th and 17th centuries marked the rise of medicine and chemistry as specialized disciplines.
• Increased emphasis on empiricism led to important developments in the understanding of the natural world and human anatomy.
• Pioneering dissections and systematic experimentation were crucial for advancements in these fields.

Changes in Astronomy

• Copernicus proposed heliocentrism, challenging the geocentric model previously supported by Ptolemy.
• His theory faced resistance from both Catholic and Protestant groups, as it conflicted with biblical interpretations.
• Tycho Brahe contributed by combining elements of the old Ptolemaic system with Copernican elements, suggesting a hybrid model.

Galileo's Contributions

• Galileo is recognized as a father of the scientific method with significant early experiments recorded in history.
• His improvements on the telescope enabled observation of celestial bodies, including Jupiter's moons and phases of Venus.
• His findings supported heliocentrism, challenging Church doctrine, ultimately leading to his house arrest for noncompliance.

Sir Isaac Newton's Influence

• Newton formulated the Three Laws of Motion and the Universal Law of Gravity, reinforcing the heliocentric model.
• His work on light led to the invention of the reflecting telescope and a foundational understanding of the color spectrum.
• Newton's discoveries have had a lasting impact on various fields, including science and mathematics.

Johannes Kepler's Foundations of Planetary Motion

• Kepler discovered three laws governing planetary motion, shifting the understanding of the solar system's mechanics.
• His First Law states planetary orbits are elliptical, with the Sun at one focus.
• The Second Law indicates varying planetary speeds, while the Third Law establishes a mathematical relationship between orbital period and distance from the Sun.

Development of the Scientific Method

• The scientific method is a systematic approach to establishing scientific knowledge, prioritizing empirical evidence.
• Originated from Aristotle’s works and gained prominence through thinkers like Sir Francis Bacon and later Galileo and Newton.
• René Descartes proposed an alternative rationalistic method, but Bacon’s empirical approach had a more lasting influence.

Overview of the Scientific Revolution

• The Scientific Revolution led to major scientific discoveries intertwined with philosophical and religious shifts in European society.
• Its duration is debated, generally considered from the 15th to the late 17th century.
• The revolution emphasized interconnectedness between science, philosophy, education, religion, and politics.

Causes of the Scientific Revolution

• Contributions from Persian and Indian mathematicians enriched European mathematical knowledge.
• The Renaissance fostered advancements in art and science, heavily relying on geometric and mathematical principles.
• The Reformation's changes in doctrine and culture prompted new approaches to scientific inquiry.

Effects of the Scientific Revolution

• Inaugurated the Enlightenment, promoting ideas of natural rights and emphasizing reason and logic.
• Inspired subsequent technological developments, including those during the Industrial Revolution.

Practical Impacts

• Heliocentrism drastically redefined astronomical perspectives, moving away from geocentrism.
• Philosophical ideas such as Deism emerged, likening God to a watchmaker who does not intervene post-creation.

Shift in Worldview

• The Scientific Revolution encouraged a transition from superstitions towards empirical evidence and logical reasoning.
• Empiricism and skepticism became foundational principles in scientific approaches, underscoring the value of observable evidence in knowledge acquisition.
