... There is a shortcut that scientists and engineers use to state the precision of a measurement when writing down the measurement. For example, if you measure the width of a box of chalk with a school-type ruler, you might get an answer of 6.1 cm. Since the ruler is only marked in increments of 0. ...

... • All measurements are approximations— no measuring device can give perfect measurements without experimental uncertainty. By convention, a mass measured to 13.2 g is said to have an absolute uncertainty of plus or minus 0.1 g and is said to have been measured to the nearest 0.1 g. In other words, ...

... 1. Definition and Manipulation A surd is an expression involving a square root, cube root etc., whose value is irrational. Examples are 2 , 3 10 etc. Note that 9 and 20.25 are not surds, because they have rational values, namely 3 and 4.5 respectively. We use surds rather than decimals because the s ...

... The remaining six empty circles form a hexagon. We must place the digit 3 in one of the bottom 3 circles (since it cannot be adjacent to 2). Once we have chosen where to place 3, we are left filling the hexagon with the digits 4 through 8. At this point the locations of 1 and 2 are irrelevant, so we ...

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.
