  2. article Sports Perspective: One last Hoo-Rah for the Ooh-Aah Man

    Wednesday, March 13, 2013 4:00 am

    It got a little louder than usual in McKale Center on Saturday when the Wildcats beat their long-time rival Arizona State, 73-58, completing their season sweep of the Sun Devils. However, the increase in volume wasn’t due to the fans excitement of seeing the Cats beat down their rivals, nor was it because it was senior night; as Arizona said goodbye to Solomon Hill, Mark Lyons and Kevin Parrom. The real reason for all the ruckus was the retirement of Joe Cavaleri, also known as the “Ooh Aah Man”.

  6. article What's Up UA? - Arizona Adds Women's Sand Volleyball

    Thursday, January 17, 2013 9:07 am

     

    Competition will begin in 2014 for the UA's 20th varsity sport. Steve Walker, the UA's indoor volleyball associate head coach, will be the new program's first head coach.

     
     

    University of Arizona Director of Athletics Greg Byrne has announced that his department has added women's sand volleyball as a varsity sport.

    The sport, which enjoys a spring competition schedule, will be the 20th varsity sport sponsored by the department. Steve Walker has been named the new program's first head coach. Official competition will begin in spring 2014.

    "This is an exciting day for the University of Arizona and our volleyball program," said Byrne. "With our strengths as an athletics department – including strong indoor volleyball, great interest from our fans and weather that is very conducive to outdoor activity – it's a natural fit for us."

    Walker, currently the UA's indoor volleyball associate head coach, will serve as the program's first leader. He served as an assistant coach with the Wildcats for three seasons from 2003-05, helping to lead the program to three NCAA Tournament appearances, including a trip to the Elite Eight in 2005. He left Arizona after the 2005 season to become the women's volleyball head coach at the UC Davis, where he has coached for two seasons before returning to Arizona in 2007.

    "I would like to thank Greg and all involved for this opportunity to be the first-ever head sand volleyball coach here at the University of Arizona," said Walker. "Throughout this hiring process, it is evident that this athletics department is excited about bringing an emerging sport like sand volleyball to this campus and community and plan to grow with it in the coming years."

    "Sand volleyball is one of the fastest growing sports in the country," said Deputy Director of Athletics Rocky LaRose. "With growing national interest, and in particular within the high school ranks in the state of Arizona, this was a natural fit. In fact, Arizona is the first high school interscholastic association to add sand volleyball as an official varsity sport. I'm excited for the new opportunities for our women, and thrilled to continue to grow our women's programs."

    At UC Davis, Walker became the Aggies' eighth head volleyball coach, guiding the program through its final year of reclassification to NCAA Division I status in 2006, and during its first year of membership in the Big West Conference. During his tenure at UC Davis, Walker was selected to coach the Northern California Volleyball Association Youth Division team at the Global Challenge in Maribor, Slovenia, during July of 2006. In 2010, he was invited back to coach the NCVA Youth team at the USA Volleyball High Performance Championship in Fort Lauderdale, Fla.

    Walker received his "AAA" rating, the highest level pro/am rating as a player in the California Beach Volleyball Association series from 1997-99, and multiple times he was an Arizona Beach Volleyball Association tournament winner from 2003-06.

    A collegiate volleyball player at Long Beach State, Walker finished his career as the school's all-time leader in assists per game. The starting setter for two seasons, he was named AVCA All-America and All-Mountain Pacific Sports Federation in 1995, after leading the NCAA in assists and assists per game.

    "We're fortunate to have Steve as our first head coach," said David Rubio, Arizona's indoor volleyball head coach. "He has a strong background in sand volleyball and will put us a step ahead of many programs right from the start."

    Women's sand volleyball is an emerging sport worldwide – as witnessed by its success at recent Olympic Games – and within NCAA circles. Fifteen universities sponsored the sport in 2011-12, its inaugural year, and 29 will compete in 2012-13. Further, 47 schools are considering sponsorship in 2013-14.

    In order to be an officially sponsored NCAA championship sport, there must be 40 competing institutions in two consecutive seasons. Within the Pac-12 Conference, four schools presently sponsor the sport (California, Stanford, UCLA, USC) with at least one other member considering adding the sport.

    Additionally, Arizona was the first state in the nation to add sand volleyball as a high school varsity sport in 2011-12, with California following in 2012-13. Currently, there are more than 350 youth club participants in the sport in the Arizona region.

    Sand volleyball was added by the NCAA in August 2011 for Division I competition. The roster size in this sport will grow as the number of scholarships increase and will have a maximum roster size of 14 student-athletes by 2014-15.

    Sand volleyball features five two-woman teams ranked by ability, and each duo plays against the corresponding team or teams from other schools. In a dual meet, the winning team is the school winning three of five matches. Individual matches are two sets played to 21 points, with a tiebreaker set to 15, if needed. All sets are rally scoring and must be won by two points.

    The sport is the first added by the UA since women's indoor track and field in 1998. Previously, Arizona added women's soccer in 1994.

    Arizona currently sponsors 11 women's sports (basketball, cross country, golf, gymnastics, soccer, softball, swimming and diving, tennis, indoor track and field, outdoor track and field and volleyball) and eight men's sports (baseball, basketball, cross country, football, golf, swimming and diving, tennis and outdoor track and field).

    Arizona has won 21 national championships and 118 conference titles in its athletic history.

  8. article Testing Einstein's E=mc2 in Outer Space

    Tuesday, January 8, 2013 8:55 am

    UA physicist Andrei Lebed has stirred the physics community with an intriguing idea yet to be tested experimentally: The world's most iconic equation, Albert Einstein's E=mc2, may be correct or not depending on where you are in space.
    According to the Theory of General Relativity, objects curve the space around them. UA physicist Andrei Lebed has proposed an experiment using a space probe carrying hydrogen atoms to test his finding that the equation E=mc2 is correct in flat space, but not in curved space.

UA physicist Andrei Lebed has proposed an experiment using a space probe carrying hydrogen atoms to test his finding that the equation E=mc2 is correct in flat space, but not in curved space. (Illustration: NASA)
     
     The simplest atom found in nature, hydrogen, consists only of a nucleus orbited by one electron. Lebed's calculations indicate that the electron can jump to a higher energy level only where space is curved. Photons emitted during those energy-switching events (wavy arrow) could be detected to test the idea.

    With the first explosions of atomic bombs, the world became witness to one of the most important and consequential principles in physics: Energy and mass, fundamentally speaking, are the same thing and can, in fact, be converted into each other. 

    This was first demonstrated by Albert Einstein’s Theory of Special Relativity and famously expressed in his iconic equation, E=mc2, where E stands for energy, m for mass and c for the speed of light (squared). 
     
    Although physicists have since validated Einstein’s equation in countless experiments and calculations, and many technologies including mobile phones and GPS navigation depend on it, University of Arizona physics professor Andrei Lebed has stirred the physics community by suggesting that E=mc2 may not hold up in certain circumstances. 
     
    The key to Lebed’s argument lies in the very concept of mass itself. According to accepted paradigm, there is no difference between the mass of a moving object that can be defined in terms of its inertia, and the mass bestowed on that object by a gravitational field. In simple terms, the former, also called inertial mass, is what causes a car’s fender to bend upon impact of another vehicle, while the latter, called gravitational mass, is commonly referred to as “weight.”
     
    This equivalence principle between the inertial and gravitational masses, introduced in classical physics by Galileo Galilei and in modern physics by Albert Einstein, has been confirmed with a very high level of accuracy. “But my calculations show that beyond a certain probability, there is a very small but real chance the equation breaks down for a gravitational mass,” Lebed said.
     
    If one measures the weight of quantum objects, such as a hydrogen atom, often enough, the result will be the same in the vast majority of cases, but a tiny portion of those measurements give a different reading, in apparent violation of E=mc2. This has physicists puzzled, but it could be explained if gravitational mass was not the same as inertial mass, which is a paradigm in physics. 
     
    “Most physicists disagree with this because they believe that gravitational mass exactly equals inertial mass,” Lebed said. “But my point is that gravitational mass may not be equal to inertial mass due to some quantum effects in General Relativity, which is Einstein’s theory of gravitation. To the best of my knowledge, nobody has ever proposed this before.”
     
    Lebed presented his calculations and their ramifications at the Marcel Grossmann Meeting in Stockholm last summer, where the community greeted them with equal amounts of skepticism and curiosity. Held every three years and attended by about 1,000 scientists from around the world, the conference focuses on theoretical and experimental General Relativity, astrophysics and relativistic field theories. Lebed’s results will be published in the conference proceedings in February.
     
    In the meantime, Lebed has invited his peers to evaluate his calculations and suggested an experiment to test his conclusions, which he published in the world's largest collection of preprints at Cornell University Library (see Extra Info).
     
    “The most important problem in physics is the Unifying Theory of Everything – a theory that can describe all forces observed in nature,” said Lebed. “The main problem toward such a theory is how to unite relativistic quantum mechanics and gravity. I try to make a connection between quantum objects and General Relativity.”
     
    The key to understand Lebed’s reasoning is gravitation. On paper at least, he showed that while E=mc2 always holds true for inertial mass, it doesn’t always for gravitational mass.
     
    “What this probably means is that gravitational mass is not the same as inertial,” he said. 
     
    According to Einstein, gravitation is a result of a curvature in space itself. Think of a mattress on which several objects have been laid out, say, a ping pong ball, a baseball and a bowling ball. The ping pong ball will make no visible dent, the baseball will make a very small one and the bowling ball will sink into the foam. Stars and planets do the same thing to space. The larger an object’s mass, the larger of a dent it will make into the fabric of space. 
     
    In other words, the more mass, the stronger the gravitational pull. In this conceptual model of gravitation, it is easy to see how a small object, like an asteroid wandering through space, eventually would get caught in the depression of a planet, trapped in its gravitational field. 
     
    “Space has a curvature,” Lebed said, “and when you move a mass in space, this curvature disturbs this motion.” 
     
    According to the UA physicist, the curvature of space is what makes gravitational mass different from inertial mass. 
     
    Lebed suggested to test his idea by measuring the weight of the simplest quantum object: a single hydrogen atom, which only consists of a nucleus, a single proton and a lone electron orbiting the nucleus. 
     
    Because he expects the effect to be extremely small, lots of hydrogen atoms would be needed. 
     
    Here is the idea:
     
    On a rare occasion, the electron whizzing around the atom’s nucleus jumps to a higher energy level, which can roughly be thought of as a wider orbit. Within a short time, the electron falls back onto its previous energy level. According to E=mc2, the hydrogen atom’s mass will change along with the change in energy level. 
     
    So far, so good. But what would happen if we moved that same atom away from Earth, where space is no longer curved, but flat?
     
    You guessed it: The electron could not jump to higher energy levels because in flat space it would be confined to its primary energy level. There is no jumping around in flat space. 
     
    “In this case, the electron can occupy only the first level of the hydrogen atom,” Lebed explained. “It doesn't feel the curvature of gravitation.”
     
    “Then we move it close to Earth’s gravitational field, and because of the curvature of space, there is a probability of that electron jumping from the first level to the second. And now the mass will be different.”
     
    “People have done calculations of energy levels here on Earth, but that gives you nothing because the curvature stays the same, so there is no perturbation,” Lebed said. “But what they didn't take into account before that opportunity of that electron to jump from the first to the second level because the curvature disturbs the atom.”
     
    “Instead of measuring weight directly, we would detect these energy switching events, which would make themselves known as emitted photons – essentially, light,” he explained.  
     
    Lebed suggested the following experiment to test his hypothesis: Send a small spacecraft with a tank of hydrogen and a sensitive photo detector onto a journey into space. 
     
    In outer space, the relationship between mass and energy is the same for the atom, but only because the flat space doesn’t permit the electron to change energy levels. 
     
    “When we're close to Earth, the curvature of space disturbs the atom, and there is a probability for the electron to jump, thereby emitting a photon that is registered by the detector,” he said. 
     
    Depending on the energy level, the relationship between mass and energy is no longer fixed under the influence of a gravitational field.
     
    Lebed said the spacecraft would not have to go very far. 
     
    “We’d have to send the probe out two or three times the radius of Earth, and it will work.” 
     
    According to Lebed, his work is the first proposition to test the combination of quantum mechanics and Einstein’s theory of gravity in the solar system. 
     
    “There are no direct tests on the marriage of those two theories,” he said. “ It is important not only from the point of view that gravitational mass is not equal to inertial mass, but also because many see this marriage as some kind of monster. I would like to test this marriage. I want to see whether it works or not.”
