This document discusses science and technology during the Renaissance period. Key developments included advances in astronomy through Copernicus placing the sun at the center of the solar system and Kepler's laws of planetary motion. Medicine advanced through the work of Vesalius on anatomy and Harvey's description of blood circulation. Major scientific figures were Galileo, who made important astronomical observations with his telescope, Descartes, who pioneered analytical geometry, and Leonardo Da Vinci, who made contributions across many fields. The Renaissance saw many important technological inventions and was a period of growth in scientific thinking.

7. Important scientific developments
•Alchemy
•Alchemy is the study of the transmutation
of materials through obscure processes. It
is sometimes described as an early form of
chemistry.
•Paracelsus was an alchemist and physician
of the Renaissance. The Paracelsians
added a third element, salt, to make a
trinity of alchemical elements.

8. •Astronomy
Nicolaus Copernicus (1473-1543)
-was Renaissance polymath
responsible for what some have
called the “Copernican
Revolution.”
-Copernicus placed the sun at
the centre of the universe, rather
than the earth which contradicts
the Ptolemaic System (Geocentric
view)
-published his theory in 1543,
in his On the Revolutions of the
Celestial Spheres

9. Johannes Kepler (1571-1630)
-is responsible for creating
Kepler’s laws of planetary motion.
These laws include that the orbit of
every planet is an ellipse with the Sun
at one of the two foci, that a line
joining a planet and the Sun sweeps
out equal areas during equal
intervals of time, and that the square
of the orbital period of a planet is
directly proportional to the cube of a
semi-major axis of its orbit.

10. Medicine
The development of modern
neurology began in the 16th
century with Vesalius, who
described the anatomy of the brain
and other organs; he had little
knowledge of the brain's function,
thinking that it resided mainly in
the ventricles.
Few effective drugs existed,
beyond opium and quinine.

11. Medicine cont.
 William Harvey provided a
refined and complete
description of the circulatory
system.
 The most useful tomes in
medicine, used both by
students and expert
physicians, were materiae
medicae and pharmacopoeiae.

21. SCIENTIST OF THE ERA

23. Galileo Galilei (1564-1642)
•The Telescope
-Galileo did not invent the telescope (Dutch
spectacle makers receive that credit), but he
was the first to use the telescope to study the
heavens systematically.
•Sunspots
-Galileo observed the Sun through his
telescope and saw that the Sun had dark
patches on it that we now call sunspots.

24. •The Moons of Jupiter
-Galileo observed 4 points of
light that changed their positions
with time around the planet
Jupiter. They were the 4 brightest
moons of Jupiter, which are now
commonly called the Galilean
moons (Galileo himself called
them the Medicea Siderea---the
``Medician Stars'').

25. • The Phases of Venus
•Galileo used his telescope to
show that Venus went
through a complete set of
phases, just like the Moon.
This observation was among
the most important in human
history, for it provided the
first conclusive observational
proof that was consistent with
the Copernican system but
not the Ptolemaic system.

26. •Geometric and
Military Compass
•Galileo
thermometer
•Concept of Inertia
•Leaning Tower of
Pisa experiment

28. RENE DESCARTES(March 31, 1569),
•Father of Modern Philosophy
•Analytical Geometry
•Used of reasoning that contribute to scientific
method
•Believed that everything should be doubted
until proven by reason.

30. Leonardo da Vinci (1452–1519)
-Leonardo was an Italian polymath,
regarded as the epitome of the "Renaissance
Man", displaying skills in numerous diverse
areas of study.
-Aside from his famous paintings he is
also renowned in other fields like
hydrodynamics, mathematics, mechanical
engineering, optics, physics, pyrotechnics, and
zoology.

31. Da Vinci’s Contributions
Flying Machine
Helicopter (Aerial
Screw)

32. Bridges and hydraulics
War machines

33. •the Vitruvian Man, is a
study of the proportions
of the human body,
linking art and science in
a single work that has
come to represent
Renaissance Humanism.

34. Francis Bacon
(January 22 1561 – 9 April 1626)
He was an English philosopher,
statesman, scientist, jurist, orator, and
author. His ideas for a universal reform
of knowledge into scientific methodology
and the improvement of mankind's state
using the Scientific method are
presented. He has been reputed as the
"Father of Experimental Science"

35. Gerardus Mercator (March 5, 1518)
• Mercator's disciplines were
cartography and geography.
From 1535-1536 Mercator made
terrestrial globes for several
rich individuals. In 1537
Mercator constructed a globe of
the stars. He was the first to
use longitude and latitude for
sailors. Mercator was also very
good at making an accurate
map of Western Europe.
