[- Centillion -]The highest number recognized by orthodox mathematics is the Centillion. Any number higher than a Centillion is considered an unimaginable abstraction belonging to the realm of infinity.
Here is a list from greatest to least in value:
[- Decimal System -]The Incas and certain other pre Columbian tribes in Peru developed the Decimal System hundreds of years before it was used in Europe.
[- Prime Numbers -]Michael Cameron, 20, from Canada proved 213,466,917-1 is prime on November 14, 2001. Although this prime took only a few weeks on his 800 MHz AMD computer, it took nearly two and half years and tens of thousands of computers for the GIMPS project to test well over 100,000 unsuccessful candidates. Congratulations to Michael and every GIMPS contributor for their part in this remarkable find.
[- Sequence -]At 12:34 on May 6, 1978, there was a peculiar lining up of dates and hours that will not happen again until the year 2078. On that day the numbers in the hour 12:34 were followed by the number Sequence of the month, day, and year for May 6, 1978, which reads 5/6/78. The resulting Sequence was 12345678.
