A cute love story:
Girl- am I pretty?
Boy-No
Girl-Do u want to live with me?
Boy-No
Girl- Will you cry if I leave you?
Boy-No.
The girl got vexed and started to cry….The boy pulled her close to him and said-
“you are not pretty but prettiest…I don’t want to live with you but live for you….If you leave me I won’t cry but die!.....
That’s what true love means…………

The theories of super space and super gravity and string theory of fundamental particles, which involves the theory of Riemann surface in novel and unexpected ways, were all areas of theoretical physics which developed using the ideas which Atiyah Michael was introducing.
Atiyah Michael has received many honors during his career, in addition to the Fields Medal referred to above, and it is impossible to list more than a few here. He was elected a Fellow of the Royal Society of London in 1962 at the age of 32. He received the Royal Medal of the society in 1968 and it’s Copley Medal in 1988. He gave the Royal Society’s Bakerian Lecture on ‘Global geometry’ in 1975 and was president of the Royal Society from 1990 to 1995.

The proportions of carbohydrate in the therapeutic diet prescribed for diabetes have changed greatly from that used before and shortly after the availability of insulin in 1921. At that time patients were expected to take diets with as little as five percent total carbohydrate. This meant that they were eating a very high-fat diet.
Since diabetes is all about the levels of sugar in our bloodstream it follows that the type of food we eat will be important. Your doctor will guide you on diet after taking into account your specific condition and the medications you take. Focus on reducing fats in your diet especially high cholesterol fats. It is better to have many, small means at well spaced intervals than to have few, larger means. All insulin treated patients require detailed attention to diet. You must adhere to your doctor’s diet recommendations.

Exercise usually lowers blood sugar. That helps your body use its food supply better. Also, exercise may help insulin work well. If you are overweight, exercise plus careful attention to diet can help take off extra pounds.
Exercise is important in many other ways. It improves the flow of blood through the small blood vessels and increases your heart’s pumping power. The right exercise program may make your look and feel better. You can walk or bike, swim or hike for exercise. These are only examples and everyone is different so being sure to ask your physician if you should have any limits in your exercise program.

Telecommunications is the sending and receiving of information using electricity, radio waves or light. The information can be sound, television pictures or computer data (which itself can be numbers, words, sounds and images). Forms of telecommunications include the telephone, fax, two-way radio, television and radio broadcasting, and the internet. Most of these forms of communication require transmitting and receiving machines, and a network to link them together. The first telecommunications device was the telegraph. Messages traveled from a sending device to a receiving device as pulses of electricity, using some sort of code that both the sender and receiver understood. Practical telegraph systems were developed in the first half of the nineteenth century, and were first used for railway signaling. Early systems needed several connecting wires, but the system that eventually became standard, developed in USA Atlantic , was quickly established right around the world. The next major step in the development of telecommunications was the invention of telephone, which could transmit speech, allowing people far apart to talk to each other. British-born American Alexander Graham Bell gave the first demonstration of the telephone in 1876, and founded the Bell Bell
Athanasius Kircher was born on 2nd May 1602 in Geisa, Thuringia. In 1614-1618 Athanasius Kircher learned Greek and Hebrew at the Jesuit Gymnasium in Fulda. Epoch-making were Kircher’s labors in the domain of deciphering hieroglyphics, and, on the excavation of the so-called Pamphylian obelisk, he succeeded in supplying correctly the portions which had been concealed from him. It must be remembered that in those days little or no attention was paid to this subject, and that it was therefore in itself a great service to have taken the initiative in this branch of investigation, however lacking his efforts may have been in the fundamental principles of the science as it is known today.
Perhaps the first scientific investigation of animal luminescence was that of Athanasius Kircher, who devoted two chapters of his book Ars Magna Lucis et ‘Umbrae’ to bioluminescence. In the midst of his more scientific observations, Kircher found time to expose as a fallacy the notion that an extract made from fireflies could be used to light houses. Athanasius Kircher wrote in an astonishingly wide range of scientific subjects, including medicine, acoustics, geology, astronomy and mathematics.

Aston Francis William was born in September 1877 at Harborne, Birmingham, England. He was educated at Harhorne Vicarage School and Malvern College where his interest in science was aroused. Leaving academic life for a time, he worked for three years as a chemist in the laboratory of a brewery. At about this time, however, his interest in physics, rather that chemistry, began to predominate, his aptitude for mechanical contrivance showed itself in his design and construction of new types of pumps for evacuating vessels. From this stemmed his interest in gas discharge phenomena in evacuated tubes.
In 1903, he obtained a scholarship to Birmingham University to work in the properties of the Crookes Dark Space in discharge tubes. Within a short time, he had discovered the phenomenon, which is known as the Aston Dark Space. At the end of 1909, he accepted the invitation of Sir J.J.Thomson to work as his assistant at the Cavendish Laboratory, Cambridge, on studies of positive rays. It was during this period that he obtained definite evidence for the existence of two isotopes of the inert gas neon.
This research was interrupted by the War of 1914-1918, during which time Aston worked at eh Royal Aircraft Establishment, Farnborough, where he studied the effect of atmospheric conditions o aero plane fabrics and dopes (i.e. synthetic coatings).

Artin Emil made a major contribution to field theory, the theory of braids and, around 1928, he worked on rings with the minimum condition on right ideals, now called Artinian rings. He had the distinction of solving, in 1927, one of the 23 famous problems posed by Hilbert in 1900. Also in 1927, he gave a general law of reciprocity which included all previously known laws of reciprocity which had been discovered from the time that Gauss produced his first law.
In 1927 work, they introduced what are called today Artin-schreier cyclic extensions of degree p. in fact, in the case of prime characteristic; they proved that the field O cannot be finite extension of a proper subfield K

Aristotle philosophized on virtually every subject. He classified animals in a ‘Scala Naturae’ or ‘Chain of Being’ which consisted of God, man, mammals, oviparous with perfect eggs (e.g., birds), oviparous with non-perfect eggs (e.g., fish), insects, plants, and non living matters. He considered each link in the chain as a ‘species’. He also made extensive taxonomic studies of more than 500 animal species, dissecting many of them. The observations he published in Generation of Animals and Historia Animalum (Investigation of Animals) were meticulous, and his classification scheme conspicuously modern, departing from the prior Greek practices of using categories such as with feet/footless and winged/wingless. Aristotle suggested a tetrad of elements: earth (solid), fire (energy), water (liquid), and air (gas). Aristotle believed each element could be hot, wet, dry, or cold. He believed earth and heaven to be subject to two different sets of laws. Terrestrial dynamics consisted of natural (straight line, vertical, discontinuous, towards natural place, speed proportional to weight over density) and forced (discontinuous, towards natural place, speed proportion to force over weight) motion. Celestial dynamics was always natural, circular and continuous. He also rejected the atomic theories of Democritus.
Archimedes of Syracuse, a great Greek mathematician who flourished in Sicily. Archimedes performed numerous geometric proofs using the rigid geometric formalism outlined by Euclid, excelling especially at computing areas and volumes using the method of exhaustion. He was especially proud of his discovery for finding the volume of a sphere, showing that it is two thirds the volumes of the smallest cylinder that can contain it. At his request, the figure of a sphere and cylinder was engraved on his tombstone. In fact, it is often said that Archimedes would have invented calculus it the Greeks had only possessed a more tractable mathematical notation. By inscribing and circumscribing polygons on a circle, for instance, he was able to constrain the value of pi between 3 10/71 and 3+1/7. Archimedes was also an outstanding engineer, formulating Archimedes principle of buoyancy and the law of lever.
Apollonius of Perga was known as ‘The Great Geometer’. His works have had a great influence on the development of mathematics, in particular his famous book ‘Conics’ introduced terms which are familiar to us today such as parabola, ellipse and hyperbola.
Apollonius was also an important founder of Greek mathematical astronomy, which used geometrical models of explain planetary theory. Ptolemy in his book ‘Syntaxis’ says Apollonius introduced systems of eccentric and epicyclical motions to explain the apparent motion of the planets across the sky. This is not strictly true since the theory of epicycles certainly predates Apollonius. Nevertheless, Apollonius sis makes substantial contributions, particularly using his great geometric skills. In particular, he made a study of the points where a planet appears stationary, namely the points where the forward motion changes to a retrograde motion or the converse.
There were also applications made by Apollonius, using his knowledge of conics, to practical problems. He developed the hemicyclium, a sundial which has the hour lines drawn on the surface of a conic section giving greater accuracy.

Pyrometers are instruments made to measure high temperatures. They use numerous principles of physics, such as: absorption of heat by a metallic block (calorimetric pyrometers), thermoelectric effect (thermoelectric pyrometers), variations of resistance by temperature (electric resistance pyrometers), comparison of superficial brilliance of an examined body with that of another body at a well known temperature (optical pyrometers).
Antoine-Hippolyte Pixii was born in 1808. He made an important contribution to the development of electrical machines. Pixii’s magneto-electric machine, developed in 1832, was the first practical mechanical generator of electric current that used concepts demonstrated by Faraday.
In 1832, after the publication of Faraday’s experiments in his famous ‘Experimental Researches in Electricity’, Hippolyte Pixii, an electrical instrument maker in Paris, constructed with the aid of William Ritchie a device in which a rotating permanent magnet induced an alternating current in the field coils of a stationary horseshoe electromagnet.
Later that same year Pixii produced a second machine, at Ampere’s suggestion, with a commutator to rectify the alternative current currents. Pixii’s first device was improved upon in 1833 by Joseph Saxton of Philadelphia who used a rotating electromagnet, the inverse of Pixii’s design. The resulting magneto-electric ‘shock machine’ was regarded for many years as a toy but later found widespread use as the crank telephone bell ringer.

Galvanometer is a device used to detect and measure the flow of electricity. A simple galvanometer is a compass with a wire wrapped around it. Connect either end of the wire to whatever you want to test (such as battery). It the needle is deflected then a current has been created. The stronger current the greater the needle will be deflected.
Andre-Marie Ampere, the son of a Lyon city official, was born on 22nd January 1775 in Polemieux-au-Mount-d’Or, near Lyon. While only 13 years old Ampere submitted his first paper to the ‘Academic de Lyon’. This work attempted to solve the problem of construction a line of the same length as an arc of a circle. His method involves the use of infinitesimals but since Ampere had not studies the calculus the paper was not found worthy of publication. Shortly after writing the article Ampere began to read d’Alembert’s article on the differential calculus in the ‘Encyclopedia’ and realized that he must learn more mathematics.
Ampere was also making significant contributions to chemistry. In 1811 he suggested that an anhydrous acid prepared two years earlier was a compound of hydrogen with an unknown element, analogous to chlorine, for which he suggested the name fluorine. After concentrating on mathematics as he sought admission to the Institute, Ampere returned to chemistry after his election in 1814 and produced a classification of elements in 1816.
Ampere also worked in the theory of light, publishing on refraction of light in 1815. By 1816 he was a strong advocate of a wave theory of light, agreeing with Fresnel and opposed to Biot and Laplace who advocated a corpuscular theory. Fresnel became a good friend of Ampere’s and lodged at Ampere’s home from 1822 until his death in 1827.
In the early 1820’s Ampere attempted to give a combined theory of electricity and magnetism after hearing about experimental results by the Danish physicist Hans Christian Orsted. Ampere formulated a circuit force law and treated magnetism by postulating small closed circuits inside the magnetized substance.
The first person to develop measuring techniques for electricity, Ampere built an instrument utilizing a free moving needle to measure the flow of electricity. Its later refinement was known as the galvanometer. He used a highly sensitive galvanometer to make his measurements.
