A successful scientist is generally a good observer. He makes full 21 of the facts he observes. He doesn’t accept ideas which are not 22 on obvious facts, and therefore refuses to accept authority as the only 23 for truth. He always 24 ideas carefully and makes experiments to prove them. The rise of 25 science may perhaps be considered to 26 as far back as the 27 of Roger Bacon, the wonderful philosopher of Oxford, who lived 28 the years 1214 and 1292. He was probably the first in the middle 29 to suggest that we must learn science 30 observing and experimenting on the things around us, and he himself 31 many important discoveries. Galileo, however, who lived more than 300 years later (1564-1642), was the greatest of several great men, 32 in Italy, France, Germany, or England, began by 33 to show how many important 34 could be discovered by observation. Before Galileo, learned men believed that large bodies fell more 35 towards the earth than small ones, 36 Aristotle said so. But Galileo, going to the 37 of the leaning Tower of Pisa, let fall two 38 stones and proved Aristotle was wrong. It was Galileo’s 39 of going direct to Nature, and proving our 40 and theories by experiment, that has led to all the discoveries of modern science.
