While some students find it boring

In high school, my Science and Chemistry teacher was one of the best teachers I ever had. Mrs. Manlulu taught the class how interesting such subjects could be. She challenged each of us to apply science in our day to day lives, appreciate frogs, sun and all.

She was so smart and showed how things move and were created. She was non-Catholic, but her ways were so kind and Christian. I remember the movie Agora where the teacher shared to the students knowledge and cared for them, as well.
Inventors are people who help us. Some of them unknown while still alive, but then their gifts to humanity are noble. We thank them for all they share.

Alfred Nobel (1833-1896) Swedish

He is the son of the inventor. In 1842, Nobel's family moved to Russia, where he gained a scientific education. He finally settled in Sweden in 1859, after living in Paris and Russia. Nobel invented dynamite in a highly dangerous process that severely maimed him, killed his brother, and in one explosion, took five lives. He died extremely rich and bestowed money to create the annual Nobel Prizes.

Linus Pauling (1901- ) American

He is the creator of the modern covalent theory of bonding. Pauling also showed that sickle cell disease could be traced to changes occurring in the structure of important molecules in a victim's blood. He has won two Nobel Prizes, one for Chemistry in 1954 and the Peace Prize in 1962. He is a controversial but highly respected figure in the world of science, and undoubtedly one of the greatest chemists of the 20th century.

Joseph Priestley (1733-1804) British

Although he had no formal scientific training, Priestly constructed numerous experiments. In 1774, he discovered oxygen and eventually identified most of the common gases.

Priestly was a schoolteacher, writer and politician, whose radical views on the French Revolution were so unpopular that he emigrated to the United States.

J.J. Thomson (1851-1940) British

He became a professor at Cambridge at the age of only 28. His pioneering experimental work led to the discovery of the electron. He also discovered that gases could be made to conduct electricity, so paving the way for radio, television and radar. For this latter research, Thomson was awarded a Nobel Prize in 1906.
