Слайд 2Famous Quotes….
“Give me a spot where I can stand and I
shall move the earth.”
“Eureka! Eureka! I have found it!”
“Eureka! Eureka! I have found it!”
Слайд 3Mini Planitarium
Archimedes created a mini planetarium that was mechanical and showed
the motions of the sun, moon, and planets as viewed from the earth.
Слайд 7Contributions:
Crop irrigation and drainage/farming practices
Remove water from ships so they would
not sink (mechanical water pump)
Move sludge
Sewage plants (many substations send to main treatment plant)

Слайд 8The Law of Hydrostatic
or the Archimedes’ Principle
What Archimedes stated:
“Any solid
lighter than a fluid will, if placed in a fluid, be so far immersed that the weight of the solid will be equal to the weight of the fluid displaced.”
Слайд 9Simple Machines:
Law of the Lever
He was not the first to use
the lever but he showed that the movement of the fulcrum influences equilibrium.
Слайд 11Law of the Lever – the closer the lever is to
the fulcrum, the easier it is to move an object
Слайд 12Contributions:
Applied mechanics – moving from physical science theory to technology and
it is used to explain the effects of items when force is applied
(example: engineering)

Слайд 13Contributed to Math
Pi - Used a 96 sided polygon to determine
that the value of pi was between 3 10/71 and 3 1/7.
Слайд 14Contributed to Math
Approximating the area of a circle
He found the area
of a circle by finding the area of smaller rectangles and adding them together.
This is termed the “method of exhaustion” and led to integral calculus, which is the study of the area figures and on the volumes of solids.
