The number of cells in the human body (estimated at 3.72 × 10 13), or 37.2 trillion/37.2 T [3] The number of bits on a computer hard disk (as of 2024, typically about 10 13, 1–2 TB), or 10 trillion/10T; The number of neuronal connections in the human brain (estimated at 10 14), or 100 trillion/100 T
The law of truly large numbers (a statistical adage), attributed to Persi Diaconis and Frederick Mosteller, states that with a large enough number of independent samples, any highly implausible (i.e. unlikely in any single sample, but with constant probability strictly greater than 0 in any sample) result is likely to be observed.

The book includes some irrational numbers below 10 but concentrates on integers, and has an entry for every integer up to 42. The final entry is for Graham's number . In addition to the dictionary itself, the book includes a list of mathematicians in chronological sequence (all born before 1890), a short glossary , and a brief bibliography .
The naming procedure for large numbers is based on taking the number n occurring in 10 3n+3 (short scale) or 10 6n (long scale) and concatenating Latin roots for its units, tens, and hundreds place, together with the suffix -illion. In this way, numbers up to 10 3·999+3 = 10 3000 (short scale) or 10 6·999 = 10 5994 (long scale
Big numbers may refer to: Large numbers, numbers that are significantly larger than those ordinarily used in everyday life; Arbitrary-precision arithmetic, also called bignum arithmetic; Big Numbers, an unfinished comics series by Alan Moore and Bill Sienkiewicz
Graham's number is an immense number that arose as an upper bound on the answer of a problem in the mathematical field of Ramsey theory.It is much larger than many other large numbers such as Skewes's number and Moser's number, both of which are in turn much larger than a googolplex.
The book is divided into two parts, with the first exploring notions leading to concepts of actual infinity, concrete but infinite mathematical values. After an exploration of number systems , this part discusses set theory , cardinal numbers , and ordinal numbers , transfinite arithmetic , and the existence of different infinite sizes of sets.
Proofs That Really Count: the Art of Combinatorial Proof is an undergraduate-level mathematics book on combinatorial proofs of mathematical identies.That is, it concerns equations between two integer-valued formulas, shown to be equal either by showing that both sides of the equation count the same type of mathematical objects, or by finding a one-to-one correspondence between the different ...
