A picul / ˈ p ɪ k əl /, [1] dan [2] or tam, [3] is a traditional Asian unit of weight, defined as "as much as a man can carry on a shoulder-pole". [1] Historically, it was defined as equivalent to 100 or 120 catties, depending on time and region.
Related units include the picul, equal to 100 catties, and the tael, which is 1 ⁄ 16 of a catty. A stone is a former unit used in Hong Kong equal to 120 catties and a gwan ( 鈞 ) is 30 catties. Catty or kati is still used in Southeast Asia as a unit of measurement in some contexts especially by the significant Overseas Chinese populations ...
Thus, the liquid–liquid critical point in a two-component system must satisfy two conditions: the condition of the spinodal curve (the second derivative of the free energy with respect to concentration must equal zero), and the extremum condition (the third derivative of the free energy with respect to concentration must also equal zero or ...
The outhouse is a unit of area used in nuclear physics equal to 10 −6 barns (100 am 2 = 10 −34 m 2). The barn (b) is a unit of area used in nuclear physics equal to one hundred femtometres squared (100 fm 2 = 10 −28 m 2). The are (a) is a unit of area equal to 100 m 2. The decare (daa) is a unit of area equal to 1000 m 2.

In French Indochina, the colonial administration fixed the tael (lạng) as 100 g, which is commonly used at food markets where many items typically weigh in the 100–900 g range. However, a different tael (called cây , lạng , or lượng ) unit of 37.5 g is used for domestic transactions in gold.
A tautochrone curve or isochrone curve (from Ancient Greek ταὐτό 'same' ἴσος 'equal' and χρόνος 'time') is the curve for which the time taken by an object sliding without friction in uniform gravity to its lowest point is independent of its starting point on the curve.
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.
