DailyDirt: Pi Math

from the urls-we-dig-up dept

National Pie Day is not actually March 14th (although it really should be, if only to make it more memorable). But here's to the number, not the delicious dessert. If you'd like to read more awesome and interesting stuff, check out this unrelated (but not entirely random!) Techdirt post.

    ok calculate pi to 1 decimal place you the value 3

    you have your sequence of numbers to want to match, you make a guess, you have 0123456789 to choose from. you have a 10% chance of finding your 'sequence' in pi.

    so if you calculate pi to 10 digits and you get

    3.124567890 and your sequence size is still 1 digit (5 for example) you have 100% chance to find your sequence within your calculated value of pi.

    (10% x 10)

    so you increase your sequence size to 2 digits (eg 12), that would mean you have a 0.01% chance of finding your sequence. (10% of 10%).

    but I think even you can see that if the original number is bit enough a point is reached when no matter how large your sequence is, it will exist somewhere in the original number 100% of the time..

    I guess there is something to be said regarding the quality of mathematics education in the US..
