Play media By placing a metal bar in a container with water on a scale, the bar displaces as much water as its own volume , increasing its mass and weighing down the scale. The most widely known anecdote about Archimedes tells of how he invented a method for determining the volume of an object with an irregular shape. According to Vitruvius , a votive crown for a temple had been made for King Hiero II of Syracuse , who had supplied the pure gold to be used, and Archimedes was asked to determine whether some silver had been substituted by the dishonest goldsmith. While taking a bath, he noticed that the level of the water in the tub rose as he got in, and realized that this effect could be used to determine the volume of the crown. For practical purposes water is incompressible, [19] so the submerged crown would displace an amount of water equal to its own volume. By dividing the mass of the crown by the volume of water displaced, the density of the crown could be obtained. This density would be lower than that of gold if cheaper and less dense metals had been added. Archimedes then took to the streets naked, so excited by his discovery that he had forgotten to dress, crying ” Eureka!

Does it require more or less effort to push a loaded wheelbarrow over hard level ground than to turn around and pull it? What about when the ground is soft? Surely the clear lens would let the light through rather than casting a shadow? At constant velocity, is this a real effect?

For a history of mathematics in general, see History of mathematics In in the United States, mathematicians were desired as teachers, calculating machine operators, mechanical engineers, accounting auditor bookkeepers, and actuary statisticians One of the earliest known mathematicians was Thales of Miletus c. The number of known mathematicians grew when Pythagoras of Samos c. The first woman mathematician recorded by history was Hypatia of Alexandria AD – She succeeded her father as Librarian at the Great Library and wrote many works on applied mathematics.

Because of a political dispute, the Christian community in Alexandria punished her, presuming she was involved, by stripping her naked and scraping off her skin with clamshells some say roofing tiles. It was extensive patronage and strong intellectual policies implemented by specific rulers that allowed scientific knowledge to develop in many areas. Funding for translation of scientific texts in other languages was ongoing throughout the reign of certain caliphs, [4] and it turned out that certain scholars became experts in the works they translated and in turn received further support for continuing to develop certain sciences.

As these sciences received wider attention from the elite, more scholars were invited and funded to study particular sciences. An example of a translator and mathematician who benefited from this type of support was al-Khawarizmi. A notable feature of many scholars working under Muslim rule in medieval times is that they were often polymaths.

Examples include the work on optics , maths and astronomy of Ibn al-Haytham.

The machinery of the Tesla coil is like some dude in the bathtub sliding back and forth, splashing water electrons out of the closed end, while the tub is refilled from the ocean ground. To understand how the driving mechanism works requires a new metaphor and some answer gravy. Aside from inspiring fear, Tesla coils are useless. Truly, Tesla was a genius.

It’s a short walk through downtown Vancouver, British Columbia, but somehow the trek feels arduous. This is not because Frind is lazy. Well, Frind is a bit lazy, but that’s another matter. The problem is that he is still getting used to the idea of a commute that involves traveling farther than the distance between the living room and the bedroom.

Frind’s online dating company, Plenty of Fish, is newly located on the 26th floor of a downtown skyscraper with a revolving restaurant on the roof. The gleaming space could easily house 30 employees, but as Frind strides in, it is eerily quiet — just a room with new carpets, freshly painted walls, and eight flat-screen computer monitors. Frind drops his bag and plops himself down in front of one of them. He looks down at his desk. Like most of his advertising deals, this one found Frind.

He wrote the Katyayana Sulba Sutra, which presented much geometry , including the general Pythagorean theorem and a computation of the square root of 2 correct to five decimal places. Jain mathematicians are important historically as crucial links between the mathematics of the Vedic period and that of the “classical period. In particular, their fascination with the enumeration of very large numbers and infinities led them to classify numbers into three classes: Not content with a simple notion of infinity, they went on to define five different types of infinity: In addition, Jain mathematicians devised notations for simple powers and exponents of numbers like squares and cubes, which enabled them to define simple algebraic equations beejganita samikaran.

Jain mathematicians were apparently also the first to use the word shunya literally void in Sanskrit to refer to zero. More than a millennium later, their appellation became the English word “zero” after a tortuous journey of translations and transliterations from India to Europe. Important Jain mathematicians included Bhadrabahu d. Memorisation and recitation was also used to transmit philosophical and literary works, as well as treatises on ritual and grammar.

Modern scholars of ancient India have noted the “truly remarkable achievements of the Indian pandits who have preserved enormously bulky texts orally for millennia. The texts were subsequently “proof-read” by comparing the different recited versions.

Science writer; author, ‘The 7 Laws of Magical Thinking’ Typos in Online Dating Profiles Don’t Matter Much It appears that making typos in your personal profile does not significantly harm the impression you make, unless you type your profile wearing ski gloves. One possible exception is if you hope to date a writer or editor, or someone as uptight about language use as I am, but who would want to do that?

When I discover that I’ve let a typo slip through, I’m horrified.
