[1] The stalagmometric method (Ancient Greek: στάλαγμα, romanized: stálagma, lit. 'drop') is one of the most common methods for measuring surface tension . The principle is to measure the weight of drops of a fluid of interest falling from a capillary glass tube , and thereby calculate the surface tension of the fluid.
A set of equations describing the trajectories of objects subject to a constant gravitational force under normal Earth-bound conditions.Assuming constant acceleration g due to Earth's gravity, Newton's law of universal gravitation simplifies to F = mg, where F is the force exerted on a mass m by the Earth's gravitational field of strength g.
The Official Table of Drops, formerly issued by the British Home Office, is a manual which is used to calculate the appropriate length of rope for long drop hangings. Following a series of failed hangings, including those of John Babbacombe Lee , a committee chaired by Henry Bruce, 1st Baron Aberdare was formed in 1886 to discover and report on ...
The Chisanbop system. When a finger is touching the table, it contributes its corresponding number to a total. Chisanbop or chisenbop (from Korean chi (ji) finger + sanpŏp (sanbeop) calculation [1] 지산법/指算法), sometimes called Fingermath, [2] is a finger counting method used to perform basic mathematical operations.
Suppose we have a floor made of parallel strips of wood, each the same width, and we drop a needle onto the floor. What is the probability that the needle will lie across a line between two strips? Buffon's needle was the earliest problem in geometric probability to be solved; [ 2 ] it can be solved using integral geometry .

Estimating the box-counting dimension of the coast of Great Britain In fractal geometry , the Minkowski–Bouligand dimension , also known as Minkowski dimension or box-counting dimension , is a way of determining the fractal dimension of a bounded set S {\textstyle S} in a Euclidean space R n {\textstyle \mathbb {R} ^{n}} , or more generally ...
Meissel already found that for k ≥ 3, P k (x, a) = 0 if a = π(x 1/3).He used the resulting equation for calculations of π(x) for big values of x. [1]Meissel calculated π(x) for values of x up to 10 9, but he narrowly missed the correct result for the biggest value of x.
