**Archimedes screw**

Easily pumps water to higher levels,

The Archimedes screw was first used to pump water out of ships then was used for irrigation. The screw is still used in many regions of the world.

Just some Pics.

Principle

Principle

Archimedes' principle indicates that the upward buoyant force that is exerted on a body immersed in a fluid, whether fully or partially submerged, is equal to the weight of the fluid that the body displaces. Archimedes' principle is a law of physics fundamental to fluid mechanics. He discovered this in the Bath.

Wait!!! He discovered this in the bath tub!

Hahaha!!!!

Fun-Fact

Archimedes

may have used

his theory to find

out if gold laurels

are less dense than

solid gold

**Life as Archimedes**

Archimedes was born 287 BC in seaport city Syracuse, Sicily.

when the years are

BC(before christ)

the smaller the

number, the later the

year.

Formula:

Buoyancy(a)=Bottom(b)-Top(t)

a=b-t

find t

12=52-t

52-12=t

40=t

lets try one...

20=b-12

the answer to the question was

b=32!

**Archimedes**

**Who was**

Archimedes spent most of his efforts on mathematics. he calculated areas and volumes and defined Pi.There are also a few other discoveries...two we will learn today!! :D

Great therome-The theory of the circle

Around 225 bc Archimedes produced a short

treatise titled Measurement of a Circle the first proposition of which gave a penetrating analysis of circular area. befor adressing this classic work however we first need to examine what was known about circular areas where he arrived appon the scene.

Geometers of the time would have known that regardless of the circle in questionthe ration of the circumference of a circle to its diameter is always the same

we would say c1/d1=c2/d2

c is the circumference and d ios the diameter or the circles. the ration of a circles circumference to its diameter is constant and modern modern mathmaticians define pi to be this ratio. c/d=pi or c=pi(d)
