## Fibonacci Introduced the Modern Numeral System to Europe Fact

Leonardo Fibonacci introduced the modern decimal numeral system (the Hindu–Arabic numeral system) to Europe in 1202. Before this Roman numerals were used.

Infinity (∞) is a concept that describes something that is “not bound” (in theory), typically in math and physics where it has many real world applications.

Srinivasa Ramanujan had no formal mathematics training in his early years. He did his research in isolation, rediscovering old theorems and producing new ones.

A system is any “bound”, finite, set of physical and/or conceptual properties (elements) such as physical objects, rules, or space time coordinates.

Gravity is the result of the curvature of spacetime by matter. Non-symmetric acceleration of matter produces gravitational waves that ripple across the universe at light speed.

Infinity (∞) isn’t a number, it’s a concept. It describes something that can’t be expressed by a “finite” natural or real number.

There are different types of infinity (∞) which differ by size, countability, “flavor” and more. Most types have practical real world applications.

No “thing” (including particles) can travel faster than light speed, but some “non-things” can. In both ways “nothing travels faster than the speed of light”.

Einstein’s mass-energy equivalence equation (E=mc2) shows that mass and energy are equivalent (but not “exactly the same”) properties of a physical system.

Pi (π) is an irrational number, meaning it represents a real number with a non-repeating pattern that can’t fully be expressed.

In practice, human action often has paradoxical or unintended effects. Sometimes effects or side effects even have the exact opposite effect as intended.
