2The hyperbolic paraboloid(not to be confused with a

hyperboloid) is a doubly ruled surface shaped like a saddle. In

a suitable coordinate system, a hyperbolic paraboloid can be

represented by the equation

For c>0, this is a hyperbolic paraboloid that opens up along the x-

axis and down along the y-axis (i.e., the parabola in the plane

x=0 opens upward and the parabola in the plane y=0 opensdownward).

How do we know this better?

The Repository for Germinal Choice was a sperm

bank that existed from from 1980 to 1999. It is

commonly believed to have accepted only donations

fromX, although in fact it accepted donations fromnon-X, also. The first baby conceived from the

project was a girl born on April 19, 1982. Founded by

Robert Klark Graham, the repository was dubbed the

"X sperm bank" by media reports at the time. Theonly contributor who became known publicly wasY,

X recipient in physics. What did this inspire in pop

culture

Gary Dean Anderson (born 1947) is an influential graphic

designer and architect. He is most well known as the designer

of the X, one of the most readily recognisable logos in the

world. His design for a symbol to embody the concept of Y

has been compared to iconic trademarks such as those for

Coca-Cola and Nike.It has been called one of Americas most

important design icons,it is one of the most recognizable

graphic symbols in the world and has helped to encourage

global Y. In some countries, such as the UK, the symbolcarries such implicit meaning that it requires government

permission to be used.What it iiis?

The nameXis a playful allusion to the event's origins, with

reference to the programmer slang term, foobar: X arose as an

open-to-the-public alternative to Foo Camp, which is an

annual invitation-only (for Friends of O'Reilly) participant-

driven conference.

The first X was held in Palo Alto, California, from August 1921,

2005, in the offices of Socialtext. It was organized in less than

one week, from concept to event, with 200 attendees. Since

then, Xs have been held in over 350 cities around the world, inNorth America, South America, Africa, Europe, the Middle

East, Australasia and Asia.(recently held in bangalore as well)

7 Excerpts from an article on physOrg.com

Motivated by the desire to determine the simplest 3-D structure that could

take advantage of mechanical instability to collapse reversibly, a group of

engineers at MIT and Harvard University were stymieduntil one of

them happened across a collapsible, spherical toy that resembled the

structures they'd been exploring, but with a complex layout of 26 solid

moving elements and 48 rotating hinges.

This is the "XY," a hollow, spherical object made of soft rubber containingno moving parts, but fashioned with 24 carefully spaced dimples. When the

air is sucked out with a syringe, the thin ligaments forming columns

between lateral dimples collapse.

The researchers named their new structure for its use of Xing and its

resemblance to buckyballs, spherical all-carbon molecules whose name wasinspired by the geodesic domes created by architect-inventor Buckminster

Fuller.

XY is the first morphable structure to incorporate Xing as a desirable

engineering design element. The Xing process induces folding in portions

of the spheresimilar to the way paper folds in origami.

The X was invented by Walter and Tom Davies in Llanelli,

Wales in 1904. At the time motor cars were made without

X.Their company, Y Iron Mongers had agents distributing the

U.S.A., Brussels, Paris, and Italy.The word "Y" is sometimes

used interchangeably in countries that were once part of the

British Empire such as Bangladesh, India, and Malta.

The first to equip cars with such an assembly were the Ramblers

made by Thomas B. Jeffery Company. and yeah Y is kinda X's

synonym.

______________was produced first in 1878 by Fahlberg, a chemist working

on coal tar derivatives in Remsen's laboratory at the Johns Hopkins

University. The sweet taste of__________ was discovered when Fahlberg

noticed a sweet taste on his hand one evening, and connected this with the

compound that he had been working on that day. Fahlberg and Remsen

published articles on benzoic sulfimide in 1879 and 1880. In 1884, now

working on his own in New York City, Fahlberg applied for patents in

several countries, describing methods of producing this substance that he

named _________. Fahlberg would soon grow wealthy, while Remsen

merely grew irate, believing that he deserved credit for substances

produced in his laboratory. On the matter, Remsen commented, "Fahlbergis a scoundrel. It nauseates me to hear my name mentioned in the same

breath with him."

In Japan, the western part of the country (Kyoto andwest) uses 60 Hz and the eastern part (Tokyo and east)uses 50 Hz. This originates in the first purchases ofgenerators from AEG in 1895, installed for Tokyo, and

General Electric in 1896, installed in Osaka. Theboundary between the two regions contains four back-to-back HVDC substations which convert the frequency;these are Shin Shinano, Sakuma Dam, Minami-

Fukumitsu, and the Higashi-Shimizu FrequencyConverter

The _________ is shown without the tail and in a symmetrical diamond form.

The geometry of diamond shaped kite with its right-hand rule can also be

viewed as a stylized form of the Wheatstone bridge. It has been said that

this bridge with its galvanometer also depicts the earliest observation of

electrical phenomena by Thales, and the source of the word electricity. The

bridge is used as a precise measurement tool. Folklore surrounding the

Wheatstone bridge reminds us that the linemen of yesteryear used it to

predict the location of a break in a telegraph line to within the distance

between two poles. And further, they would often bet coffee on which pole

the break was closest. In a similar manner the kite, represents the kite used

by Benjamin Franklin when he discovered electricity in lightning.

18In 1946, after many years of endeavour, Norman, Hymie and Maxwell Goldberg

finally invent the first air-conditioning unit that can be fitted inside a car. So

thrilled and confident are these three brothers that they decide to sell it tothe largest car manufacturer in the world Ford

They install their only working unit in one of their cars and choosing a hot day,drive to Fords Head Office in Detroit. On arrival, they ask to see Henry Ford

himself, but as they dont have an appointment, they have to use all their

charm to persuade his secretary to help them. Within minutes, shes telling

Mr Ford that sitting in her office are three well dressed gentlemen with amost exciting invention that will help sell more Ford cars.

Henry Ford immediately asks them to join him in his office. But they refuse,asking him instead to go with them to the car park to see their invention. Heagrees and when they reach the Goldbergs car, all four get in. As its now

very hot outside, the Goldbergs turn on their air-conditioning unit. Almostimmediately the car begins to cool down. Henry Ford is very excited andasks if they have patented their invention which they are pleased toconfirm. So he invites them back to his office for some discussion.

One hour later, the Goldbergs are offered $3million for their invention. But theyrefuse. They not only want $5million but they also desire recognition byhaving a label on every one of their units saying, A Goldberg Air-Conditioning unit.

But Henry Ford says that there is no way he is going to put the nameGoldberg on millions of his Ford cars (everyone in America knows that he

is more than a little bit anti-Semitic.) So they go back to haggling andeventually reach an agreement for the product. The offer now is $4.5millionplus the display in each car of something related to the three brothers.

20In his patent application of February 6, 1959, W described his

new device as a body of semiconductor material ... whereinall the components of the electronic circuit are completely

integrated. W won the 2000 Nobel Prize in Physics for the

invention..W's work was named an IEEE Milestone in 2009.

X also came up with his own idea of an integrated circuit half a

year later than W. His chip solved many practical problems

that W's had not. Produced at Fairchild Semiconductor, it was

made of silicon, whereas X's chip was made of germanium.

A certain flip flop is named after W

22The design posted by X on the Internet spread like wildfire in cyberspace in

october 2011.It drew hundreds of thousands of posts, and commemorativecaps and T-shirts peddled on eBay featured his design.

X, 19, said he was not the first to come up with the design after commentssurfaced on Twitter that a U.K.-based designer, known as Raid71 on the web,created the original design in May.

X, a student at Hong Kong's Polytechnic University School of Design,acknowledged he was not the original creator of the design but said he did not

"rip off" the UK designer.

He went on to say,

"I still arrived at the solution on my own, and my conscience is still clear, but I'mmore than happy to acknowledge the fact that somebody did it before me,"

Raid71's design differed from X's only in dimension and proportion.

23This clumping behavior applies to any small macroscopic object that floats or

clings to the surface of a liquid. This can include a multitude of things,

including hair particles in shaving cream and fizzy beer bubbles. The effectis not noticeable for boats and other large floating objects because the forceof surface tension is relatively small at that scale. what effect

24X usually results in quadriplegia and the inability to speak in otherwise

cognitively intact individuals. Those with X may be able to communicate

with others through coded messages by blinking or moving their eyes,which are often not affected by the paralysis. The symptoms are similar tothose of sleep paralysis. Patients who have X are conscious and aware withno loss of cognitive function. They can sometimes retain proprioception andsensation throughout their body. Some patients may have the ability tomove certain facial muscles, most often some or all of the extraocular eye

muscles. Individuals with X lack coordination between breathing and voice.This restricts them from producing voluntary sounds, even though the vocalcords themselves are not paralysed.

Still from Y,whose central

character who has X.

25He worked in Copenhagen at the Carlsberg Laboratory, associated withCarlsberg

Brewery, where he was head of the Chemistry departmentfrom 1876 to 1900.

He was given the job to determine the amount of protein in the grain used in the maltindustry. Less protein meant more beer. X found the answer was in developing a

technique to determine nitrogen with accuracy but existing methods in analytical

chemistry related to proteins and biochemistry at the time were far from

accurate.

X method in analytical chemistry is a method for the quantitative determination of

nitrogen in chemical substances.

A software protection X is a small piece of hardware that plugs intoan electrical connector on a computer and serves as an electronic"key" for a piece of software; the program will run only when the X isplugged in. It is mainly used for the purpose of copy protection orauthentication of software to be used on that system.

Electrically, X mostly appear as two-interface security tokens withtransient data flow that does not interfere with other functions and apull communication that reads security data from the it. These areused by some proprietary vendors as a form of copy protection ordigital rights management, because it is generally harder to replicatea it than to copy the software it authenticates. Without the X, thesoftware may run only in a restricted mode, or not at all.
