History[ edit ] InEdward Kasner 's nine-year-old nephew, Milton Sirotta, coined the term googolwhich isthen proposed the further term googolplex to be "one, followed by writing zeroes until you get tired". Einsteinsimply because he had more endurance and could write for longer". Size[ edit ] A typical book can be printed with zeros around pages with 50 lines per page and 50 zeros per line.
Combinatorial processes rapidly generate even larger numbers. The factorial function, which defines the number of permutations on a set of fixed objects, grows very rapidly with the number of objects.
Combinatorial processes generate very large numbers in statistical mechanics. These numbers are so large that they are typically only referred to using their logarithms. Computers and computational complexity[ edit ] This section possibly contains original research.

September Learn how and when to remove this template message Between andpersonal computer hard disk sizes increased from about 10 megabytes bytes to over gigabytes bytes.
But what about a dictionary-on-disk storing all possible passwords containing up to 40 characters? In his paper Computational capacity of the universe,  Seth Lloyd points out that if every particle in the universe could be used as part of a huge computer, it could store only about bits, less than one millionth of the size such a dictionary would require.
However, storing information on hard disk and computing it are very different functions.
On the one hand storage currently has limitations as stated, but computational speed is a different matter. It is quite conceivable[ by whom? Still, computers can easily be programmed to start creating and displaying all possible character passwords one at a time.
Such a program could be left to run indefinitely. By contrast, the universe is estimated to be Computers will presumably continue to get faster, but the same paper mentioned before estimates that the entire universe functioning as a giant computer could have performed no more than operations since the Big Bang.
This is trillions of times more computation than is required for displaying all character passwords, but computing all 50 character passwords would outstrip the estimated computational potential of the entire universe.
Problems like this grow exponentially in the number of computations they require, and they are one reason why exponentially difficult problems are called "intractable" in computer science: The traditional division between "easy" and "hard" problems is thus drawn between programs that do and do not require exponentially increasing resources to execute.
Such limits are an advantage in cryptographysince any cipher -breaking technique that requires more than, say, the operations mentioned before will never be feasible.
For example, one way of finding the greatest common divisor between two digit numbers is to compute all their factors by trial division. But the Euclidean algorithmusing a much more efficient technique, takes only a fraction of a second to compute the GCD for even huge numbers such as these.
As a general rule, then, PCs in can perform calculations in a few minutes.
Limits on computer storage are comparable. However, it has practical and theoretical challenges that may never be overcome, such as the mass production of qubitsthe fundamental building block of quantum computing.The MegaPenny Project shows you lots and lots of pennies, up to one quintillion!

An analysis of representative literature concerning the widely recognized ineffective learning of "place-value" by American children arguably also demonstrates a widespread lack of understanding of the concept of place-value among elementary school arithmetic teachers and among researchers themselves.
