God did not create the universe and the "Big Bang" was an inevitable consequence of the laws of physics, the eminent British theoretical physicistStephen Hawking argues in a new book.

In "The Grand Design," co-authored with U.S. physicist Leonard Mlodinow, Hawking says a new series of theories made a creator of the universe redundant, according to the Times newspaper which published extracts on Thursday.
"Because there is a law such as gravity, the universe can and will create itself from nothing. Spontaneous creation is the reason there is something rather than nothing, why the universe exists, why we exist," Hawking writes.

"It is not necessary to invoke God to light the blue touch paper and set the universe going."
Hawking, 68, who won global recognition with his 1988 book "A Brief History of Time," an account of the origins of the universe, is renowned for his work on black holes, cosmology and quantum gravity.

Since 1974, the scientist has worked on marrying the two cornerstones of modern physics -- Albert Einstein's General Theory of Relativity, which concerns gravity and large-scale phenomena, and quantum theory, which covers subatomic particles.


His latest comments suggest he has broken away from previous views he has expressed on religion. Previously, he wrote that the laws of physics meant it was simply not necessary to believe that God had intervened in the Big Bang.
He wrote in A Brief History ... "If we discover a complete theory, it would be the ultimate triumph of human reason -- for then we should know the mind of God."
In his latest book, he said the 1992 discovery of a planet orbiting another star other than the Sun helped deconstruct the view of the father of physics Isaac Newton that the universe could not have arisen out of chaos but was created by God.

Canadian center for Electron Microscopy has developed a new powerful microscope that is world's most powerful microscope till date. According to Gianluigi Botton, Director of Canadian center for Electron Microscopy, says that the power of this microscope can be thought as equivalent to "taking Hubble Telescope and aiming it at atomic level".


Titan

Titan 80-300 Cubed

This powerful microscope named Titan 80-300 Cubed was installed at the University early in the summer, and since then it has been put through its paces to achieve unprecedented resolution.
This microscope is so powerful that it can easily identify atoms, measure their chemical state and even probe the electrons that bind them together.

According to vice-president of Mc Master, Mr. Elbestawi this microscope will make McMaster a hub for a fast growing field.

Really Impressive Microscope

A group of international scientists who visited McMaster were really impressed by the amazing capabilities of this microscope. This microscope can help scientist to discover new things in biological and physical sciencesDean of Engineering David Wilkinson sees the microscope through another lens.

Titan's ability can probe structure of solid materials to the atomic level and this will have an amazing impact on development and commercialization of new technologies from biomedical devices to water quality monitoring and improved energy storage systems.

Cost of Microscope

This microscope has been build in Netherlands by FEI Company with a cost of about $15 million. This microscope can help to examine everyday products with its Nano details that can improve the efficiency of these products.


What This Microscope Can Do?

This microscope can be used to produce more efficient lighting and better solar cells, to study proteins and drug-delivery materials to target cancers. It will assess atmospheric particulates, and help create lighter and stronger automotive materials, more effective cosmetics, and higher density memory storage for faster electronic and telecommunication devices.

Funding

Funding for the microscope instrumentation was provided by the Canada Foundation for Innovation, the Ontario Innovation Trust, the Ministry of Research and Innovation of Ontario and the Ontario Ministry of Economic Development and Trade, through a partnership with FEI and McMaster University.

Alexander Graham Bell first invented the telephone at the age of 29, in 1877. The following year, the Bell Telephone Company was established, during which time he married Mabel Hubbard and setting off on a honeymoon across Europe for an entire year.

Alexander Graham Bell's fame is attached to the success of the telephone, but in fact bell embarked upon several other projects. He remained an ambitious and creative man throughout his life, during which he would continue to learn, create and challenge himself to improve the modern world. Bell engaged in many different scientific studies including kites, airplanes, tetrahedral structures, sheep-breeding, desalinization, water distillation, hydrofoils and artificial respiration, as documented in his various journals and logbooks.

The Invention of the telephone empowered Bell, in terms of financial security, which allowed him to devote himself to developing his other ideas and interests. In 1881, Bell won France's Volta prize of $10,000 which he used to et up the Volta Laboratory in Washington, D.C. This is where Bell teamed up with Chichester Bell and Charles Sumner Tainter, to produce a marketable version of the Phonograph, first thought up by Thomas Edison. A secondary laboratory was set up in 1885, at Beinn Bhreagh, near Baddeck, where he brought together an intelligent young team to follow new ideas and concepts.

The photophone was the first invention created by Bell after the telephone, which allowed sound to be transmitted via a beam of light. Charles Sumner Tainter and Bell himself developed the photophone using sensitive selenium crystal and a mirror which vibrated in reply to sound. The first successfully transmitted photophone message was sent in 1881 over a distance of 200 yards. Bell hailed the photophone as "the greatest invention I have ever made; greater than the telephone." This invention is the fundamental principle which modern day lasers and fiber optics rely on, although many other principles had to be recognised before these were brought into effect.

Alexander Graham Bell's interest in heredity, led him to explore, first of all the deaf followed by sheep born with genetic abnormalities. He conducted various sheep-breeding experiments in which he strived to increase the number of twin and triplet births. Bell also created an electromagnetic device to detect a bullet. following President Garfield being shot by an assassin and having the bullet lodged inside him. He continued to work on this and thus invented the telephone probe, which would make a telephone receiver click when it connected with metal.

Bell's son, Edward, died due to respiratory problems which inspired Bell to invent a metal vacuum jacket which assists breathing. He also invented an audiometer which detected small hearing problems, conduced various experiments relating to energy recycling and substitute fuels, and attempts of separating salt from seawater.

The bulk of Bell's time was then spent exclusively on flight, as Bell enjoyed a challenge. The 1890's saw Bell develop a keen interest in propellers and kites, which led him to create a new kite design, based on a tetrahedron. In 1907, Bell established the Aerial Experiment Association with Glenn Curtiss, William "Casey" Baldwin, Thomas Selfridge and J.A.D. McCurdy, four young engineers with a passion for creating airborne transport. It took the group 2 years to create four powered aircraft, the Silver Dart being the stand-out project which made it's first flight in Canada on February 23rd, 1909.

Bell ended his career by concentrating on hydrofoils, looking to improve their performance, and in 1919, himself and Casey Baldwin built a hydrofoil which set a water-speed record which would not be beat for 44 years.

Shortly before Bell died, he told a reporter, "There cannot be mental atrophy in any person who continues to observe, to remember what he observes, and to seek answers for his unceasing how's and why's about things."

Astronomers at UCLATennessee State University and theCalifornia Institute of Technology have reported that two terrestrial planets orbiting a mature sun-like star some 300 light-years from Earth recently suffered a violent collision."

Astronomer are now writing a report on this event in December issue of the Astrophysical Journal.


Collision

ACCORDING TO ASTRONOMERS:

According to Benjamin Zuckerman, (Professor of physics and astronomy in UCLA), this collision was just like if Earth and Venus collided with each other,". It is the first time that Astronomers have seen such collision.
Co-author of the report and astronomer in Tennessee State University, Dr. Gregory Henry says, "If any life was present on either planet, the massive collision would have wiped out everything in a matter of minutes - the ultimate extinction event." After that collision a massive disk of infrared-emitting dust has encircled the star.

HOW THE REASEARCH CAME OUT:

Zuckerman, Henry and Michael Muno, were studying a star BD+20307 located in the constellation Aries and surrounded by a 1 million times more dust than is orbiting our sun. These astronomers gathered X-ray data using the orbiting Chandra X-ray Observatory and brightness data from one of TSU's automated telescopes in southern Arizona, hoping to measure the age of the star.

They thought that BD+20 307 was relatively young, a few hundred million years old , with the massive dust ring which signals the final stages in the formation of the star's planetary system. But Alycia Weinberger of Carnegie Institution of Washington announced that BD+20 307 is actually a close binary star means two stars orbiting around their common center of mass.

The new spectroscopic data collected after this announcement confirmed that BD+20 307 is composed of two stars, both very similar in mass, temperature and size to our own sun and they orbit about their common center of mass every 3.42 days. Further research also shown that these stars are much more older than estimated before. Instead of few hundred million years these stars are several billion years old.

The planetary collision in BD+20 307 was not observed directly but rather was inferred from the extraordinary quantity of dust particles that orbit the binary pair at about the same distance as Earth and Venus are from our sun. Henry said. "If this dust does indeed point to the presence of terrestrial planets, then this represents the first known example of planets of any mass in orbit around a close binary star."

BD+20 307: THE EARLIER THOUGHTS 

Zuckerman and colleagues first reported in the journal Nature in July 2005 that BD+20 307, then still thought to be a single star, was surrounded by more warm orbiting dust than any other sun-like star known to astronomers. The dust is orbiting the binary system very closely, where Earth-like planets are most likely to be and where dust typically cannot survive long. Small dust particles get pushed away by stellar radiation, while larger pieces get reduced to dust in collisions within the disk and are then whisked away.

Thus, the dust-forming collision near BD+20 307 must have taken place rather recently, probably within the past few hundred thousand years and perhaps much more recently, the astronomers said.

NOW THE TWO IMPORTANT QUESTION IS:

After this all research the two most important questions before astronomers are:

1.) How do planetary orbits become destabilized in such an old, mature system?

2) Could such a collision happen in our own solar system?

According to some esteemed astronomers, there is small probability for collisions of Mercury with Earth or Venus sometime in the next billion years or more.


Collision

According to Zuckerman, major collisions have occurred in our solar system's in past. It is believed by many astronomers that our moon was formed from the collision of two planetary embryos - the young Earth and a body about the size of Mars - a crash which created tremendous debris, some of which condensed to form the moon and some of which went into orbit around the young sun. The collision of an asteroid with Earth 65 million years ago, which ultimately resulted in the demise of dinosaurs is also an example of such collision.

FUNDING

This research is federally funded by the National Science Foundation and NASA and also by Tennessee State University and the state of Tennessee, through its Centers of Excellence program
