My Python Code[edit]

Placeholder

print("This is just a placeholder.")

Remember[edit]

Remember is a place I put random stuff that I find interesting in case I forget about it or some thing I would like research more in depth later.

$\sum _{n=0}^{\infty }2^{n}=-1$ .

$5!=1\times 2\times 3\times 4\times 5=120$

$\Pi =3.14159265358979$ I'm working on memorizing 25 digits of π

$\lfloor 1.4\rfloor =1$ The floor and ceiling functions give us the nearest integer up or down.

$\lceil 1.4\rceil =2$ The floor and ceiling functions give us the nearest integer up or down.

21, 4, 0, and −2048 are integers, while 9.75, 5 ¹⁄₂, and √2 are not.

ℕ or N means either { 0, 1, 2, 3, ...} or { 1, 2, 3, ...}.[edit]

he choice depends on the area of mathematics being studied; e.g. number theorists prefer the latter; analysts, set theorists and computer scientists prefer the former. To avoid confusion, always check an author's definition of N.[edit]

ℤ or ℤ means {..., −3, −2, −1, 0, 1, 2, 3, ...}.[edit]

ℤ⁺ or ℤ^> means {1, 2, 3, ...} .[edit]

ℤ^* or ℤ^≥ means {0, 1, 2, 3, ...} .[edit]

x ≤ y means x is less than or equal to y.[edit]

x ≥ y means x is greater than or equal to y.[edit]

(The forms <= and >= are generally used in programming languages, where ease of typing and use of ASCII text is preferred.)[edit]

${\frac {1}{3}}+{\frac {1}{3}}+{\frac {1}{3}}=1$

Leucippus was a Greek philosopher of the 5th century BCE. He is credited with founding atomism, with his student Democritus. Leucippus divided the world into two entities: atoms, indivisible particles that make up all things, and the void, the nothingness between the atoms. Leucippus's ideas were influential in ancient and Renaissance philosophy. They were a precursor to modern atomic theory, but the two are only superficially similar. Leucippus's atoms come in infinitely many forms, all in constant motion, creating a deterministic world created by the collisions of atoms. The soul is viewed as an arrangement of spherical atoms, cycled through the body by respiration and creating thought and sensory input. Little is known of his life, with a few scholars doubting that he existed, attributing his ideas purely to Democritus. Two works are attributed to Leucippus, The Great World System and On Mind, but all of his writing has been lost except for one sentence. (Full article...)
