5. Hippocratic Oath (original)
I will prescribe regiments for the good of my
patients according to my ability and my
judgment and never do harm to anyone
I will not give a lethal drug to anyone if I am
asked, nor will I advise such a plan; and similarly
I will not give a woman a pessary (device) to
cause an abortion.

6. In every house where I come I will enter only for
the good of my patients.
If I keep this oath faithfully, may I enjoy my life
and practice my art…but if I swerve from it or
violate it, may the reverse be my lot.

7. Euclid
• Father of Geometry
• Founded a school of Mathematics
• His textbook, Elements, formed the basis for
all geometry textbooks

8. Euclid

9. Eratosthenes
• Determined the distance around the earth
• Devised the lines of latitude and longitude
found on maps today.

10. Albert the Great
• A Dominican friar
• Played an important role in introducing
Muslim documents to medieval universities

11. Albert the Great

12. Roger Bacon
• Made significant contributions in the areas of
physics, geography and optics

13. Roger Bacon

14. • Medieval science came to a sudden halt with
the appearance of the Black Death
• During the Renaissance, tradition was
replaced with observations
– Scientists experimented, recorded findings, and
reached conclusions

15. Copernicus
• He believed that the earth revolved around
the sun, not the sun around the earth.

16. Copernicus

17. Galileo Galilei
• Used the telescope to support Copernicus’s
ideas

18. Galileo Galilei

19. • People were scared of Copernicus and
Galileo’s findings.
– If they were right, the Bible must be wrong
because is says that the sun appears to move
through the heavens
– Also if the earth, man’s home, is not at the center
of the universe, then perhaps man is not
important in this world.
