An Elementary and Perhaps Useful Cheat Sheet for Names of Big Numbers

JF Ptak Science Books

I thought to include this little cheat sheet for the names of large numbers—I didn’t know the name for some big number, and had to go and find it. Here’s a bunch that I cobbled quickly together to serve as a recipe should you ever need a big-number-name and not know it.  I’ve only used the modern American and British versions of these names, and I’ve avoided numbers that just won’t work for me here (as I’m just looking for simple stuff) like

10^{10^{10^{10^{10^{1.1}}}}} (~ googolplex1,941,887,670,000), (years),  which is the “scale of an estimated Poincaré recurrence time for the quantum state of a hypothetical box containing a black hole with the estimated mass of the entire universe, observable or not, assuming a certain inflationary model with an inflation whose mass is 10−6 Planck masses.”  so says University of Albert physicist Donald Page, quantum cosmologist and Stephen Hawking co-author. 

A googol is already a big number at 1×10100; a googolplex is terrifically larger, being 10googol,  or. 10(10100).

I’ve left out almost everything, actually, including the beautiful numbers from ancient India, including the sublimely-named “untold” as exactly 1010*2122  appearing in Bodhisattva‘s maths in the Avataṃsaka Sūtra..

Hindu theology incorporates spectacular leaps of time, numbers which jump geometrically, reaching ever greater heights, describing a small part of a small bit of teh beginning of the Cycle of Brahma.  (See far below.)

I’ll save the suspense—the largest number identified here is 1×10^3003, which is a millinillion, and it looks like this:
100.000.000.000.000.000.000.000.000.000.000.000.00 0.000.000.000.000.000.000.000.000.000.000.000.000. 000.000.000.000.000.000.000.000.000.000.000.000.00 0.000.000.000.000.000.000.000.000.000.000.000.000. 000.000.000.000.000.000.000.000.000.000.000.000.00 0.000.000.000.000.000.000.000.000.000.000.000.000. 000.000.000.000.000.000.000.000.000.000.000.000.00 0.000.000.000.000.000.000.000.000.000.000.000.000. 000.000.000.000.000.000.000.000.000.000.000.000.00 0.000.000.000.000.000.000.000.000.000.000.000.000. 000.000.000.000.000.000.000.000.000.000.000.000.00 0.000.000.000.000.000.000.000.000.000.000.000.000. 000.000.000.000.000.000.000.000.000.000.000.000.00 0.000.000.000.000.000.000.000.000.000.000.000.000. 000.000.000.000.000.000.000.000.000.000.000.000.00 0.000.000.000.000.000.000.000.000.000.000.000.000. 000.000.000.000.000.000.000.000.000.000.000.000.00 0.000.000.000.000.000.000.000.000.000.000.000.000. 000.000.000.000.000.000.000.000.000.000.000.000.00 0.000.000.000.000.000.000.000.000.000.000.000.000. 000.000.000.000.000.000.000.000.000.000.000.000.00 0.000.000.000.000.000.000.000.000.000.000.000.000. 000.000.000.000.000.000.000.000.000.000.000.000.00 0.000.000.000.000.000.000.000.000.000.000.000.000. 000.000.000.000.000.000.000.000.000.000.000.000.00 0.000.000.000.000.000.000.000.000.000.000.000.000. 000.000.000.000.000.000.000.000.000.000.000.000.00 0.000.000.000.000.000.000.000.000.000.000.000.000. 000.000.000.000.000.000.000.000.000.000.000.000.00 0.000.000.000.000.000.000.000.000.000.000.000.000. 000.000.000.000.000.000.000.000.000.000.000.000.00 0.000.000.000.000.000.000.000.000.000.000.000.000. 000.000.000.000.000.000.000.000.000.000.000.000.00 0.000.000.000.000.000.000.000.000.000.000.000.000. 000.000.000.000.000.000.000.000.000.000.000.000.00 0.000.000.000.000.000.000.000.000.000.000.000.000. 000.000.000.000.000.000.000.000.000.000.000.000.00 0.000.000.000.000.000.000.000.000.000.000.000.000. 000.000.000.000.000.000.000.000.000.000.000.000.00 0.000.000.000.000.000.000.000.000.000.000.000.000. 000.000.000.000.000.000.000.000.000.000.000.000.00 0.000.000.000.000.000.000.000.000.000.000.000.000. 000.000.000.000.000.000.000.000.000.000.000.000.00 0.000.000.000.000.000.000.000.000.000.000.000.000. 000.000.000.000.000.000.000.000.000.000.000.000.00 0.000.000.000.000.000.000.000.000.000.000.000.000. 000.000.000.000.000.000.000.000.000.000.000.000.00 0.000.000.000.000.000.000.000.000.000.000.000.000.
