See the cartoon above in which the man says to a person sitting next to him – She couldn’t change a $20 bill. The lady seems to have bought popcorns worth $20 for she is poor at math.

Math quotes #5

Proof is an idol before whom the pure mathematician tortures himself.
by Arthur Stanley Eddington, The Nature of the Physical World

There was a young man from Trinity,
Who solved the square root of infinity.
While counting the digits,
He was seized by the fidgets,
Dropped science, and took up divinity.
Author Unknown

One cannot escape the feeling that these mathematical formulas have an independent existence and an intelligence of their own, that they are wiser than we are, wiser even than their discoverers…
by Heinrich Hertz

In the binary system we count on our fists instead of on our fingers.
Author Unknown

The laws of nature are but the mathematical thoughts of God.
by Euclid

In most sciences one generation tears down what another has built and what one has established another undoes.  In mathematics alone each generations adds a new story to the old structure.

Mathematics is the supreme judge; from its decisions there is no appeal.
by Tobias Dantzig

Although he may not always recognize his bondage, modern man lives under a tyranny of numbers.
by Nicholas Eberstadt, The Tyranny of Numbers: Mismeasurement and Misrule

The mathematics are usually considered as being the very antipodes of Poesy.  Yet Mathesis and Poesy are of the closest kindred, for they are both works of the imagination.
by Thomas Hill

The temperature of Heaven can be rather accurately computed.  Our authority is Isaiah 30:26, “Moreover, the light of the Moon shall be as the light of the Sun and the light of the Sun shall be sevenfold, as the light of seven days.”  Thus Heaven receives from the Moon as much radiation as we do from the Sun, and in addition 7*7 (49) times as much as the Earth does from the Sun, or 50 times in all.  The light we receive from the Moon is one 1/10,000 of the light we receive from the Sun, so we can ignore that….  The radiation falling on Heaven will heat it to the point where the heat lost by radiation is just equal to the heat received by radiation, i.e., Heaven loses 50 times as much heat as the Earth by radiation.  Using the Stefan-Boltzmann law for radiation, (H/E) temperature of the earth (-300K), gives H as 798K (525C).  The exact temperature of Hell cannot be computed….  [However] Revelations 21:8 says “But the fearful, and unbelieving…shall have their part in the lake which burneth with fire and brimstone.”  A lake of molten brimstone means that its temperature must be at or below the boiling point, 444.6C.  We have, then, that Heaven, at 525C is hotter than Hell at 445C.
From Applied Optics, vol. 11, A14, 1972

Sometimes it is useful to know how large your zero is.

The hardest arithmetic to master is that which enables us to count our blessings.
by Eric Hoffer, Reflections On The Human Condition

Mathematics is the only good metaphysics.
by William Thomson Baron Kelvin of Largs

The most savage controversies are those about matters as to which there is no good evidence either way.  Persecution is used in theology, not in arithmetic.
by Bertrand Russell

Music is the pleasure the human mind experiences from counting without being aware that it is counting.
by Gottfried Leibniz

How many times can you subtract 7 from 83, and what is left afterwards?  You can subtract it as many times as you want, and it leaves 76 every time.

India’s contribution to the field of Mathematics

India has contributed considerably to the field of Mathematics for long. The research on Mathematics in India is as old as Rigveda – the oldest scripture to date today and some of the best known contributors being Aryabhata, Brahmagupta & Bhaskara II. These Indian mathematicians made early contributions to the study of the decimal number system, invention of zero, negative numbers, arithmetic, trigonometry and algebra. It was later when these mathematical concepts were transmitted to the Middle East, China & Europe and led to further developments that now form the foundations of many areas of mathematics all across the planet.

Development of a series of expansions for trigonometric functions, sine, cosine & arc tangent, by the Mathematicians of the Kerala School in the fifteenth century CE were a landmark in the Indian Mathematics. Their remarkable work, completed two centuries before the invention of calculus in Europe, provided what is now considered the first example of a power series (apart from geometric series). However, they did not formulate a systematic theory of differentiation and integration, nor is there any direct evidence of their results being transmitted outside Kerala.
