What is the lowest number known to man?

There's no single "lowest" number because it depends on the number system: for positive counting numbers (natural numbers), it's 1, but for whole numbers including zero, it's 0; for negative numbers, there's no lowest as they go infinitely towards negative infinity (e.g., -1, -100, -1,000,000, etc.). In advanced math, concepts like infinitesimals approach zero but aren't zero itself, showing numbers can get incredibly small, but there's always a smaller one.

Why is the number 137 so special?

The idea is quite simple, if you don't use math to explain it. 137 is the odds that an electron will absorb a single photon. Protons and electrons are bound by interactions with photons. So when you get 137 protons, you get 137 photons, and you get a 100% chance of absorption.

Why is 52 an untouchable number?

The number 52 is an "untouchable number" because it's a rare number that can't be formed by adding up the proper divisors (all divisors except the number itself) of any other integer, making it a member of a special set of numbers that are "untouched" by this specific mathematical operation, joining other untouchables like 2 and 5 in this category. 

Why is 2520 a special number?

The number 2520 is special because it's the smallest positive integer perfectly divisible by all integers from 1 to 10, making it the Least Common Multiple (LCM) of {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}, and it has fascinating connections to time (7 days x 30 days x 12 months = 2520) and various mathematical properties like being a highly composite number and the product of five consecutive integers (3×4×5×6×7).

Which number is sad?

A "sad number" (or unhappy number) in mathematics is any positive integer that, when you repeatedly replace it with the sum of the squares of its digits, never reaches the number 1, instead entering a cycle that includes 4, 16, 37, 58, 89, 145, 42, and 20, eventually returning to 4. This contrasts with "happy numbers," which do reach 1 through this process.

Is 170141183460469231731687303715884105727 prime number?

Using this algorithm with hand computations on paper, Lucas showed in 1876 that the 39-digit number (2127 – 1) equals 170,141,183,460,469,231,731,687,303,715,884,105,727, and that value is prime. Also known as M127, this number remains the largest prime verified by hand computations.

How are million, billion, trillion named?

Because English took words from both Latin and old German. "Million" comes from the Latin word "mille" which means a thousand thousand, or 1,000,000. The word billion then comes to mean a million squared, or 1,000,000,000,000 and trillion, a million cubed, or 1,000,000,000,000,000,000.
