The first materials which man discovered were copper and gold, because they occur naturally in the pure state. They were used because they could be shaped easily, gold being especially soft. The discovery that copper could be obtained in sufficient quantities for beating into vessels and weapons was an important step in the use of metals, but the discovery that copper ore would produce copper was probably accidental.

Galileo Galilei (1564-1642). Italian astronomer, physicist and mathematician Galileo Galilei changed the way we think. By inventing a mathematical approach to everyday experience, he discovered the laws of inertia, falling body and pendulum. With a telescope he built, he also made astronomic discoveries that convinced him of heliocentric view of the universe, which Copernicus had formulated earlier but had been afraid to publish. Galileo took the chance but he was forced to recant his findings before a Catholic Church tribunal in 1633.

Isaac Newton (1642-1727). A passionately religious man in a time of great scientific discovery, Isaac Newton wanted to know how God’s universe worked. His quest for answers gave us the law of gravitation, calculus, a new theory of colour and light, and the three laws of motion that form the basis of modern mechanics. Brilliant and creative, the English physicist and mathematician synthesized the discoveries of Galileo, Kepler and others, formalizing and transforming physical science.

Louis Paster (1822-1895). He was born practical problem-solver and theoretical genius. The French chemist discovered that heat would kill the unwanted micro- organisms that turned wine bitter. Soon the process of “pasteurization” was applied to many foods and drinks. Realizing that most diseases are caused by micro-organisms, he helped establish the germ theory. And using weakened microbes in vaccines to develop immunities, Paster saved countless lives and advanced the science of immunology.
