What was Archimedes discovery about sphere and cylinder?

He discovered the relationship between a sphere and a circumscribed cylinder of the same height and diameter. The volume is 4⁄3πr3 for the sphere, and 2πr3 for the cylinder. The surface area is 4πr2 for the sphere, and 6πr2 for the cylinder (including its two bases), where r is the radius of the sphere and cylinder. The sphere has a volume and surface area two-thirds that of the cylinder. A sculpted sphere and cylinder were placed on the tomb of Archimedes at his request.

What did Kelly Miller contribute to the mathematical world?

Kelly Miller's main contributions were in civil liberties rather than mathematics. He was the first person of African American origin to study at John Hopkins University but could not keep attending because of financial difficulties.

When did Isaac Newton create the Newton meter?

He created the Newton Meter 261 years ago because he wondered how to measure the weight of water.

What are the contributions of Rene Descartes in psychology?

The field of psychology looks at the relationship between the physical body and the way that our mind works. Descartes helped bridge that gap between science and philosophy in his exploration of mind body dualism theory, especially in his last work, "Passions of the Soul".

What was eudoxus of cnidus famous for?

He thought the earth was at the center of the universe and developed the theory of the Crystal spheres. He studied under Plato in Athens, Greece.

Contributions to mathematics by Carl Gauss?

Carl Friedrich Gauss (1777-1855) is widely regarded as one of the three greatest mathematicians of all times, along with Archimedes and Newton. He has completely modified the concept of rigour in mathematics and was a pioneer in Non-Euclidian Geometry. Already during his lifetime, he was praised as "greatest mathematician since antiquity" and "the Prince of Mathematicians". "Gauss combined scientific theory and practice like no other before him, or since, and even as a young man Gauss made extraordinary contributions to mathematics. His Disquisitiones arithmeticae, published in 1801, stands to this day as a true masterpiece of scientific investigation. In the same year, Gauss gained fame in wider circles for his prediction, using very few observations, of when and where the asteroid Ceres would next appear. The method of least squares, developed by Gauss as an aid in his mapping of the state of Hannover, is still an indispensable tool for analyzing data. His sextant is pictured on the last series of German 10-Mark notes, honoring his considerable contributions to surveying. There, one also finds a bell curve, which is the graphical representation of the Gaussian normal distribution in probability. Together with Wilhelm Weber, Gauss invented the first electric telegraph. In recognition of his contributions to the theory of electromagnetism, the international unit of magnetic induction is the gauss". Also math easier as an contribution made.

What is the relationship between the symbol of Pi and the word Pi?

The symbol 'π' is the Greek letter 'p' which is called "pi", like our 'p' is called 'pee'.

Who was marina neumann?

marina neumann is the one that most say created the first computer in 1830

When did Christiaan Huygens die?

Christiaan Huygens died on July 8, 1695 at the age of 66.

What college did Carl Friedrich Gauss go to?

Gauss went to the Collegium Carolinum and then the University of Gottingen

What did newton do for a living?

Isaac newton was a professor at Cambridge University from 1669. Additionally in 1696 Isaac Newton became warden of The Mint, then in 1699 he was promoted to Master of the Mint.

What is Charles Simonyi's contribution to computer programming?

Charles Simonyi developed the Hungarian notation convention, where variables are named in order to automatically reveal their type, which is particularly useful in untyped languages. For instance, a variable named iValue signifies the value is an integer, while lpcszName signifies the name is a far pointer to a constant null-terminate string. A variable named m_iData signifies the data is an integer and also a class member.

While at Xerox PARC in 1972 he assisted in the development of the Xerox Alto, an early form of PC. He also assisted in the development of Bravo, a WYSIWYG document preparation program. In 1977 he received his PhD from Stanford with a dissertation on metaprogramming, a software project management technique.

He joined Microsoft in 1981 and oversaw the development of Microsoft Word and Excel, and eventually Office. He introduced Microsoft to his Hungarian notation which is widely used throughout all Microsoft software. He left Microsoft in 2002 to co-found Intentional Software which markets intentional programming concepts.

He was awarded the Wharton Infosys Business Transformation Award in 2004 for his innovative work in information technology.

What did Kurt Godel discover?

Kurt Godel was a mathematician who proved several very deep theorems. His best know contribution has to do with the completeness of formal systems. A formal system (in mathematics) is a set of self-evident truths (called "the axioms") along with a set of rules with which the axioms may be manipulated. The result of the proper manipulation of the rules and axioms yields the so-called "theorems". These last may, in turn, be manipulated by the same set of rules to obtain more complex theorems. The argument may be applied to any theorem and all producible theorems correspond to mathematical truths. The idea is that in a formal system no reasoning (beyond the one required to apply the rules) is needed and, therefore, the chance of subjective interpretation errors is eliminated. It was hoped that by adequately establishing a very small set of axioms and proper "production" rules one would therefore be able to produce a "model" of a non-formal system. For instance, Russell and Whitehead (two British mathematicians) claimed that such model was contained in their opus "Principia Mathematica". And, furthermore, that from it all provable truths (theorems) regarding the natural numbers (all positive integers from 0 to infinity) could be derived. However, Godel rigorously proved that Rusell's claim did not hold for all cases. In fact, he proved that there are infinitely many cases when that (the non-provability of theorems) happens if the formal system is sufficiently powerful. In other words, even though there are formal systems in which all possible truths may be mechanically found, this is so only if the purported systems are simple enough to make them uninteresting (for a mathematician at least). The theorem was called "The Incompleteness Theorem of Formal Systems". It created quite a stir in the mathematical and philosophical worlds since what Godel had just proved was equivalent to proving that "truth" may not be found (even in principle) mathematically (at least in the formal sense). Or, equivalently, that there are mathematical truths which will forever remain unknown. Since the claim was (and is) that all science may be expressed in some kind of mathematical model Godel's theorem implied that there is no way to find all truths by means of a systematic (i.e. mechanical) program. A corollary of the above is that there is no way to produce artificial intelligence in the sense of a machine being able to achieve a mental development similar to that of a human being. For since any machine must obey a set of physical "hard" rules (or "laws") it is forever marred by Godel's argument of incompleteness. Thus, there are truths that no machine may find that, however, may be found by a human being (such as Godel himself). Therefore, IA is unreachable even in principle. Therefore, human beings do not obey formal dictates. There are other incompleteness theorem which Godel also proved (among his many contributions). The one described, however, is the one that is best known.

Did Charles Babbage inventor of the computer invent the laptop?

No! None of Babbage's designs would fit on a lap. The Analytical Engine (his only true computer) would have likely weighed 50 to 100 tons and was never built.

All of his designs were "industrial equipment" designed for permanent stationary factory installation.

Why is it still called Pythagoras theorem when it has been proven and is no longer a theory?

Answer #1:

The reason is that when the sides of a right angle triangle are equal it is impossible to find the exact value of its hypotenuse by using Pythagoras' theorem because it will always be an irrational number which is infinite. So therefore it remains a theorem because it has not been 100% proven.

It is for the same reason that the area of a circle which is pi*radius2 is only theoretical because the exact value of pi has never been determined which is also an irrational number.

================================

Answer #2:

The question rests on an invalid equivocation. "Theorem" and "theory" are NOT the same thing.

A theory is a set of ideas presented in an attempt to explain something that's

observed.

A theorem is a statement derived logically from other, previously accepted statements.

Pythagoras took what was already known in Geometry, and massaged and manipulated

it to show that IF those previous statements are correct, THEN C2 = A2 + B2.

How was geometry developed?

it is developed because during early people exist their lives they always use geometry

in everydays. as the people learn to use it they began doing experiments about these mathematics concern.
