A successful scientist is generally a good observer. He makes full 36 of the facts he observes. He doesn’t accept ideas which are not 37 on obvious facts, and therefore refuses to accept authority as the only 38 for truth. He always 39 ideas carefully and makes experiments to prove them.
The rise of 40 science may perhaps be considered to 41 as far back as the 42 of Roger Bacon, the wonderful philosopher of Oxford, who live 43 the years 1214 and 1292. He was probably the first in the Middle 44 to suggest that we must learn science 45 observing and experimenting on the things around us, and he himself 46 many important discoveries.
Galileo, however, who lived more than 300 years later (1564-1642), was the greatest of several great men, 47 in Italy, France, Germany, or England, began by 48 to show how many important 49 could be discovered by observation. Before Galileo, learned men believed that large bodies fell more 50 towards the earth than small ones, 51 Aristotle said so. But Galileo, going to the 52 of the leaning Tower of Pisa, let fall two 53 stones and proved Aristotle was wrong. It was Galileo’s 54 of going direct to Nature, and proving our 55 and theories by experiment, that has led to all the discoveries of modern science.
