... “I’ll finish the 27 cigarettes I have left,” she said to herself, “and never smoke another one.” It was Mrs. Puffem’s practice to smoke exactly two-thirds of each complete cigarette(the cigarettes are filterless). It did not take her long to discover that with the aid of some tape, she could stick t ...

... Let’s elaborate on this approach. We earlier noted that 100, the number in the middle, was the median number. Since this is a symmetrical series, the median is also the average number. By looking at the diagram above, instead of looking at the bracket amounts, we can visualize that each bracket ‘pai ...

Approximations of π
Approximations for the mathematical constant pi (π) in the history of mathematics reached an accuracy within 0.04% of the true value before the beginning of the Common Era (Archimedes). In Chinese mathematics, this was improved to approximations correct to what corresponds to about seven decimal digits by the 5th century.Further progress was made only from the 15th century (Jamshīd al-Kāshī), and early modern mathematicians reached an accuracy of 35 digits by the 18th century (Ludolph van Ceulen), and 126 digits by the 19th century (Jurij Vega), surpassing the accuracy required for any conceivable application outside of pure mathematics.The record of manual approximation of π is held by William Shanks, who calculated 527 digits correctly in the years preceding 1873. Since the mid 20th century, approximation of π has been the task of electronic digital computers; the current record (as of May 2015) is at 13.3 trillion digits, calculated in October 2014.
