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.

  I'm working on memorizing 25 digits of π

  The floor and ceiling functions give us the nearest integer up or down.

  The floor and ceiling functions give us the nearest integer up or down.

21, 4, 0, and −2048 are integers, while 9.75, 5 12, 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

+ or ℤ> means {1, 2, 3, ...} . edit

* 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

Anning, depicted with her dog

Mary Anning (21 May 1799 – 9 March 1847) was an English fossil collector and palaeontologist. She made discoveries of Jurassic marine fossil beds in the cliffs along the English Channel at Lyme Regis, which changed the scientific thinking about prehistoric life and the history of the Earth. Her discoveries included the first correctly identified ichthyosaur skeleton, the first two nearly complete plesiosaur skeletons, and the first pterosaur skeleton outside Germany. Her observations helped prove that coprolites were fossilised faeces and that belemnite fossils contained ink sacs. As a woman, Anning could not join the Geological Society of London and struggled to receive credit for her contributions. Henry De la Beche painted Duria Antiquior based on fossils Anning had found and sold its prints for her benefit. After her death, an article about her life was published in Charles Dickens's literary magazine All the Year Round. A statue of Anning was erected in 2022, and she has been depicted in film and in manga. (Full article...)
