The Centre Of Gravity Of Any Cylinder

I Am Persuaded That This Method [for Calculating The Volume Of A Sphere] Will Be Of No Little Service To Mathematics. For I Foresee That Once It Is Understood And Established, It Will Be Used To Discover Other Theorems Which Have Not Yet Occurred To Me, By Other Mathematicians, Now Living Or Yet Unborn.

Any Solid Lighter Than A Fluid Will, If Placed In The Fluid, Be So Far Immersed That The Weight Of The Solid Will Be Equal To The Weight Of The Fluid Displaced. On Floating Bodies I, Prop 5.

Eureka! [i Have Found It!] On Discovery Of A Method To Test The Purity Of Gold.

Man Has Always Learned From The Past. After All, You Can't Learn History In Reverse!

Eureka, Eureka! (i Found It, I Found It!).
