the department of physics and astronomy and department of aerospace engineering at texas a&m university invite the brazos valley community to get up-close and personal with science and technology later this month at the 2011 physics & engineering festival an entertaining and informative weekend scientific extravaganza for all ages no fees or tickets are required for the free annual event scheduled for saturday march 26 from 10 am to 5 pm at the george p mitchell 40 physics buildings on the texas a&m campus all events are sponsored by the department of physics and astronomy the department of aerospace engineering the texas a&m college of science the george p and cynthia woods mitchell institute for fundamental physics and astronomy and the association of former students activities will begin at 10 am with hands-on science exhibitions and engineering technology demonstrations and conclude with an interactive public lecture at 4 pm by nasa astronaut dr richard m linnehan dvm mpa who flew on four space shuttle missions and also spent time on the international space station from 10 am to 4 pm participants are encouraged to unleash their inner scientists aboard a square-wheeled bicycle and to try their hands at generating electricity or shooting balloons with lasers three of roughly 100 fun experiments and displays illustrating basic scientific and engineering technology-related concepts and principles all exhibits are manned by texas a&m faculty staff and students including representatives from the departments of chemistry mathematics and biochemistry and biophysics in addition to exhibits the daylong festival will feature three fantastic bubble shows (11 am 1 pm 2:30 pm) by internationally acclaimed bubble artist and physics showman keith michael johnson whose work has been featured on the discovery channel and in usa today and real simple family attendees also will have the opportunity to meet nasa astronaut dr charles j camarda a former flight engineer and science officer aboard the international space station in two afternoon question-and-answer sessions scheduled for 12 pm and 2 pm at 3 pm dr peter m mcintyre texas a&m professor of physics and astronomy will present green nuclear power technology for the new millennium in the stephen w hawking auditorium against the real-world backdrop of the current nuclear crisis in japan mcintyre will explain how texas a&m scientists are developing a new green nuclear power technology that can burn the spent nuclear fuel from todays power plants to produce 10 times more energy than was yet extracted from them the accelerator-driven subcritical molten-salt (adsms) technology meets all of the criteria that define a truly green energy technology finally at 4 pm linnehan will present my experiences flying on the space shuttle and space station in the primary lecture hall of the mitchell physics building in addition to detailing his adventures in orbit linnehan will share many images both from his personal collection and the hubble space telescope archive linnehan a veterinarian trained in comparative pathophysiology who has logged more than 58 days in space is currently on temporary assignment with the texas a&m university system as director for space science policy and education through a unique partnership intended to help reinvigorate space-related research critical to nasas current and future mission selected by nasa in 1992 he flew his first space shuttle mission in 1996 aboard sts-78 the life sciences and microgravity spacelab mission his four space flights aboard space shuttles columbia and endeavour included visits to the hubble space telescope and international space station as well as six evas (spacewalks) totaling 42 hours and 11 minutes prior to joining nasa linnehan earned his doctorate of veterinary medicine from the ohio state university in 1985 and was later accepted to a two-year joint internship in zoo animal medicine and comparative pathology at the baltimore zoo and the johns hopkins university following his internship he was commissioned as a captain in the us army veterinary corps where he became chief clinical veterinarian for the us navys marine mammal program camarda an associate fellow of the american institute of aeronautics and astronautics who has logged more than 333 hours in space was selected by nasa in 1996 his past assignments include: technical duties in the astronaut office spacecraft systems/operations branch; the expedition-8 back-up crew; director engineering johnson space center; and nasa engineering and safety center where he was responsible for evaluating problems and supplementing safety and engineering activities for agency programs camarda flew as a mission specialist-5 on the return-to-flight mission sts-114 discovery in 2005 during which the shuttle docked with the international space station and tested and evaluated new procedures for flight safety as well as shuttle inspection and repair techniques camarda who earned his doctorate in aerospace engineering from virginia polytechnic institute and state university in 1990 currently serves as senior advisor for innovation to the office of chief engineer at johnson space center mcintyre who has held the mitchell-heep chair in experimental high-energy physics since 2004 joined the texas a&m faculty in 1980 and leads programs of research in high energy physics accelerator physics and superconductor technology he received his phd from the university of chicago in 1973 he performed experiments with colliding beams at cern in geneva switzerland until 1975 then joined harvard university and participated in neutrino scattering experiments at fermilab in 1976 he was the first to propose making colliding beams of protons and antiprotons using the large synchrotrons at fermilab and at cern he developed several techniques for cooling intense beams of antiprotons for that purpose mcintyre is a key collaborator in the large hadron collider (lhc) at cern as well as the collider detector at fermilab (cdf) which are searching for the top quark and seeking evidence of the higgs field and supersymmetry he was named a sloan fellow in 1980-82 and a fellow of the american physical society in 2001 prior to saturdays events dr john l junkins distinguished professor of aerospace engineering at texas a&m will deliver a free public lecture close encounters with asteroid apophis: challenges and opportunities on friday (mar 25) at 7 pm in the stephen w hawking auditorium tickets are not required for the event in which junkins will discuss earths impending dates with astronomical destiny close encounters with the 1 000-foot asteroid apophis in 2029 and 2036 and the interesting learning opportunities each presents for astronomers and aerospace engineers junkins a regents professor and holder of the royce e wisenbaker chair joined the texas a&m faculty in 1985 and is a member of the national academy of engineering and the international academy of astronautics as well as a fellow of the american institute of aeronautics and astronautics (aiaa) and the american astronautical society (aas) his prolific and fundamental research advances in engineering mechanics and spacecraft dynamics navigation guidance and control have supported more than a dozen spaceflight missions and are documented in more than 300 publications including five textbooks junkins many awards and honors include the aiaa g edward pendray aerospace literature award (1990) the auburn university college of engineering outstanding aerospace engineering alumnus award (1991) the sigma xi distinguished scientist award (1992) the aiaa theodore von karman medal and lectureship (1997) the international astronautical federation frank j malina medal (1999) the institute of navigation tycho brahe award (2004) the aiaa aerospace guidance navigation and control award (2006) and the international conference on computational and experimental engineering and sciences (icces) lifetime achievement medal (2010) junkins holds a bachelors degree from auburn university and masters and phd degrees from the university of california los angeles all in aerospace engineering for the latest details regarding the 2011 physics & engineering festival including event directions and parking information please visit http://physicsfestivaltamuedu -atm- contact: shana k hutchins (979) 862-1237 or shutchins@sciencetamuedu
