Stephen William Hawking

since 1979, has held the post of Lucasian Professor of Mathematics. The chair was founded in 1663 with money left in the will of the Reverend Henry Lucas who had been the Member of Parliament for the University. It was first held by Isaac Barrow and then in 1669 by Isaac Newton. Stephen Hawking has worked on the basic laws which govern the universe. With Roger Penrose he showed that Einstein's General Theory of Relativity implied space and time would have a beginning in the Big Bang and an end in black holes. These results indicated that it was necessary to unify General Relativity with Quantum Theory, the other great Scientific development of the first half of the 20th Century. One consequence of such a unification that he discovered was that black holes should not be completely black, but rather should emit radiation and eventually evaporate and disappear. Another conjecture is that the universe has

Albert Einstein

Albert Einstein was born in Germany in 1879 and he died in 1955. He is widely considered one of the greatest physicists of all time. In 1898, Einstein met and fell in love with Mileva Maric, a Serbian classmate. Einstein married Mileva on January 6, 1903. Mileva had a daughter Lieserl, born in January, 1902. Lieserl, at the time, was considered illegitimate because the parents were unwed. Einstein married Mileva on January 6, 1903. Alber Einstein is best known for the theory of relativity, he was also awarded with the Nobel Prize in 1921 in physics for his explanation of the photoelectric effect. He enjoyed classical music and played the violin. Albert Einstein has been the subject and inspiration for a number of novels, films and plays. Einstein has received a number of posthumous honors. In 1999, he was named Person of the Century. Wedding picture of Albert Einstein and Mileva Maric.

Does the Higgs Field do something?

unknown function (the scale factor a(t)). Therefore the number of unknowns are less, than the number of equations (because the conservation of number of particles requires the density of the perfect fluid ρ = ρ0 (a0 /a(t))3 , see also [1] or you can ask for unpublished Gauss’s theorem in the curved spacetime). Therefore, an unknown X(t, x, y, z) from Dark Matter is needed. This unknown can be the purely the Higgs Field itself [1]. The singularities are the failure of General Relativity, thus the finite Higgs Field (which acts as Dark Energy, Dark Matter) do hold the curvature from divergency [1]. The mathematics of the General Relativity with Higgs Field becomes truly manageable by humans. Gtt /(8π) = −ρ − X(t, x, y, z), Grr = p − X. Let X = −Gtt /(8π) − . Where < ∞. Then Grr − Gtt /(8π) − = p(ρ) = p( ). Then by choosing arbitrary metric non-singular function a(t), one finds the , which is necessarily finite.

July 1910. Mari and Einstein divorced on 14 February 1919. Einstein married Elsa Löwenthal on 2 June 1919. Academic career On 30 April 1905, he completed his thesis, with Alfred Kleiner. Einstein's "miracle year". By 1908, he was recognized as a leading scientist. In 1911, he had calculated that, based on his new theory of general relativity, light from another star would be bent by the Sun's gravity. In 1921, Einstein was awarded the Noble Prize in Physics. Emigration from Germany, World War II and the Manhattan Project In 1933, Einstein decided to emigrate to the United States due to the rise to power of the Nazis under Germany's new chancellor, Adolf Hitler.

As it is come out in different studies, the level of Estonia's education is pretty good. Our children learn different languages, maths, history etc. at school which of course is very natural and welcome. But besides scramming just hard cold facts about chemistry or relativity theory we should also learn something which is happening around us at the moment.

Referaat loogikust Kurt Gödel

Instituudis kohtus Gödel Albert Einstein'iga, kellega nad väga hästi läbi said ja lõpuks sõpradeks said. Instituudis hakkas Gödel huvi näitama matemaatika filosoofia suunas. Ta avaldas oma esimese filosoofilise teksti aastal 1944, mille pealkirjaks oli ,,On Russell's Mathematical Logic". Oma teise teksti avaldas ta aastal 1947, pealkirjaks ,,What is Cantor's Continuum Hypothesis?". 1949. aastal avaldas ta oma kolmanda teksti, mille pealkirjaks sai ,,A Remark on the Relationship between Relativity Theory and Idealistic Philosophy". Gödeli filosoofilised tekstid ei piirdunud vaid kolmega, lisaks neile kolmele avaldas ta veel palju teisi ning isegi andis loengu 1941. aastal Yale'i Ülikoolis, teemal ,,In What Sense is Intuitionistic Logic Constructive?". Gödeli täielikkuse teoreem ja mittetäielikkuse teoreemid. Gödeli teoreem on formaalse aritmeetika mittetäielikkuses. Gödel väitis, et igas

Leonardo da Vinci died in 1519. In his will, he left all his notebooks and many of his paintings to his friend and favorite student, Francesco Melzi. Albert Einstein was scientific genius who was born in Germany. He went to school in Germany, in Switzerland, and in Italy. Albert enjoyed learning science, especially Physics. When he was ten years old, his tutor gave him adult-level books on physics and he read them avidly. Albert Einstein is best know for his "Theory of Relativity" in Physics, for explaning the law of photoelectric effect, and early understanding of quantum theory and the use of atomic energy. He wrote over 300 papers that explained physics that had never been understood before. In 1921, he was given the Nobel Prize for Physics Michael Joseph Jackson is an American recording artist, entertainer, and businessman.

The Cataclysmic Death of Stars

Astronomers also have found that some of the neutron stars left behind by supernovas zip along at 500 miles a second (800 kilometers a second), as if the explosion had imparted an enormous kick in one direction. Stronger evidence for the sound wave idea could come from two sprawling facilities, in Hanford, Washington, and Livingston, Louisiana, designed to detect gravitational waves--ripples in the fabric of space and time. Gravitational waves, predicted by Einstein's theory of general relativity but never directly observed, should be produced whenever immense masses shake and twist, as they do in the core of a supernova. If sound waves really are at work inside a collapsing star, it should vibrate only at certain frequencies, generating matching gravitational waves. Burrows calculates that for a supernova in or near our galaxy, the existing detectors could pick up these signals--clues to a big, big noise. Stars, it seems, really may go kaboom

are the basic facts about them and how to explore all these facts. The results of this research supports the idea that: Most multiverse theories are based on other theories and hypothesis. That makes multiversum theories unreliable. However, some versions of multiversums are based on knowledge that is long proven and supported by the facts. Author found out that most certan proofs for multiversum are simple widely known things like gravitation, general relativity and the fact that universe is expanding. These are also main facts that are used to explain different versions of mulitversums. As it turned out, it's difficult to say who was the first person who came up with the idea of multiuniversums. Apparently, Huge Everette III was one of them. The paper falls into nine chapters.

Albert Einstein created a new era of physics when he unified mass, energy, magnetism, electricity, and light. One of the most significant events, if not the very most significant event, of the 20th century was Einstein's writing the formula of E=mc2: energy = mass times the square of the speed of light.

Pulp Fiction is part of the pop-culture jet stream, flowing easily out of the current collective unconscious, charged with images and sounds from previous eras. RELATIVITY A N D W O R L D CULTURE Pulp Fiction is postmodern also in its sense of cultural relativity. Although the film is set in America, it is shot through with a sense of worldwide culture and a global viewpoint. T h e characters are constantly comparing one culture to another, one set of standards to another. Jules and Vincent discuss the peculiar way American fast food is named and consumed in other countries, and marvel at drug laws in other lands.

PSÜHHOLOOGIA ALUSED

Praktiliselt kõik keeled võimaldavad väljendada tegevuse agente (subjekte) ja objekte (Gerrig & Banaji, 1994). Keeltevahelised erinevused ilmnevad näiteks mineviku väljendamisel , ainsuses ja mitmuses, pööramisel, käänamisel, soo puhul ja paljudel muudel juhtudel. Kas nende keeleliste erinevuste tõttu mõtlevad inimesed erinevates keeltes erinevalt? Seda küsimust käsitleb keelelise sõltuvuse (keelelise suhtelisuse ehk keelelise relatiivsuse, linguistic relativity) hüpotees. Keelelise sõltuvuse hüpoteesi kohaselt on eri keelte rääkijail erinevad tunnetuslikud süsteemid ja need tunnetuslikud süsteemid mõjutavad inimeste mõtlemist. Niisiis mõtlevad araablased keelelise sõltuvuse hüpoteesi kohaselt kaamelitest teisiti kui teised rahvad. See tähendab, et keelelise sõltuvuse hüpoteesi kohaselt vormib keel mõtlemist. Seda hüpoteesi nimetatakse ka Sapir ­ Whorfi hüpoteesiks (Sapir, 1941; Whorf, 1964). Omal ajal oli see hüpotees
