| Question | Answer |
|---|---|
| Archimedes | Ancient Greek mathematician and scientist from Syracuse who discovered buoyancy, invented the water screw, and famously shouted "Eureka!" |
| Archimedes' Principle | States that the buoyant force on an object submerged in a fluid is equal to the weight of the fluid displaced by the body. |
| Archimedes' Screw | A simple machine featuring a helical blade inside a cylinder that converts rotational motion to linear force to lift water uphill. |
| The Sand Reckoner | Archimedes' treatise in which he developed a system using "myriads" to calculate that 10^63 grains of sand could fit in the universe. |
| Method of Exhaustion | An ancient geometric technique of inscribing and circumscribing polygons around a circle to approximate pi and calculate areas. |
| Archimedean Property | A property of real numbers stating that for any two positive real numbers x and y, there exists an integer n such that n*x > y. |
| Palimpsest | A recovered erased manuscript containing lost works by Archimedes, including his Method of Mechanical Theorems and On Floating Bodies. |
| King Hiero's Crown | The golden crown Archimedes tested for purity by measuring its water displacement in a bathtub to determine its density. |
| Heat Ray | A legendary weapon Archimedes reportedly designed using parabolic mirrors to focus sunlight and set invading Roman ships on fire. |
| Stomachion | A 14-piece geometric tangram-like puzzle described by Archimedes that can be arranged into a square in 536 different ways. |
