(b) Science means application of the right method or formulae to arrive at the correct fact and truth of our universe- the Scientific Method.
(c) The scientific method involves learning by observation, questioning, reasoning and experimentation.
(d) Scientists need instruments, implements and mathematics in order to observe, measure, experiment and calculate to test their theories and establish scientific truths.
ADVERTISEMENTS:
(e) Renaissance men tested the scientific knowledge of the Greeks and Arabs. Similarly, the achievements of the Renaissance scientists have become the starting point of modern day science.
(f) Leonardo da Vinci dissected bodies of criminals to make his paintings of the human body more accurate. He designed a flying machine from observing a bird in flight.
(g) The mathematical proofs by Copernicus and Kepler were ultimately proved correct by Galileo’s use of the telescope to establish that the earth revolves around the Sun and not vice versa.
(h) In physics, Galileo proved that heavy or light bodies, when thrown from a height, would reach the ground at the same time.
