講座內容:

        使用各種地球和天基儀器,我們對宇宙結構、進化和最終命運的了解在過去100年中經歷了兩次巨大的變化。目前公認的宇宙模型包含暗物質河南22选5开奖结果、暗能量、wimps、machos、3度微波河南22选5开奖结果、原始霧、殘余中微子和其他奇怪的東西河南22选5开奖结果。盡管目前宇宙學很復雜,但我們對宇宙中96%的物質和能量密度沒有基本的了解。我們將重點探討下一代科學家的巨大發現潛力河南22选5开奖结果。

        Using a variety of Earth- d and space- d instruments, our knowledge of the structure, evolution, and ultimate fate of the Universe has undergone two dramatic changes in the last 100 years. The currently accepted model of the Universe contains Dark Matter, Dark Energy, WIMPs, MACHOs, 3 degree microwaves, primordial fog, relic neutrinos, and other oddities. In spite of the sophistication of the current cosmology, we do not have a fundamental understanding of 96 percent of the matter and energy density in the Universe. We will explore this model with emphasis on the tremendous discovery potential for the next generation of scientists.

主講人簡介:

        Michael Smith教授是美國橡樹嶺國家實驗室杰出的物理學家河南22选5开奖结果,美國物理學會會士。Smith教授本科就讀于芝加哥大學河南22选5开奖结果,在耶魯大學獲博士學位,并在加州理工大學做博士后。之后,在橡樹嶺國家實驗室從事核天體物理科研工作20余年,任橡樹嶺國家實驗室天體物理組組長,天體物理項目主任。由于他在核天體物理模擬工作以及核結構實驗測量方面的突出貢獻河南22选5开奖结果,他被授予美國能源部青年科學家、美國青年科學家、杰出科學家等榮譽稱號。曾主持美國能源部多項重點基金、聯合自然科學基金等。發表文章上百篇,發布國家專利多項。

        Michael Smith's expertise is in accelerator measurements of thermonuclear reactions relevant for understanding how stars explode. Michael is a Laboratory Distinguished Scientist in the ORNL Physics Division, where he leads the Experimental Astrophysics Group. Prior to coming to ORNL, he received an undergraduate degree in Physics from the University of Chicago, a Ph.D. from Yale University, and worked as a Postdoctoral Research Fellow at the California Institute of Technology. At ORNL, he leads an interdisciplinary effort using beams of radioactive subatomic nuclei, nuclear data assessments, and computer simulations to study how stars explode. He is Deputy Manager of the SECAR Project, a 12M$ mass separator system that is under construction at the Facility for Rare Isotope Beams (FRIB) for direct measurements of reactions that cause stars to explode. Until recently,  Michael was the elected Chairman of the 1400 member FRIB User Organization, the largest organization in low energy nuclear science in the U.S. He is a Fellow of the American Physical Society and has won the Presidential Early Career Award for Scientists and Engineers, the highest award given to young researchers in the United States. He has also won numerous ORNL awards including Scientific Paper of the Year, Science Communicator of the Year, Director's Award for Community Service, and Educational Champion. He has been featured on National Geographic's Naked Science TV show, the JASON science education project, and the Discovery Channel / Siemens STEM Online Academy. He has pioneered and oversees 6 online software systems and websites that enable scientists from around the world to share their research results. He collaborates with researchers from around the world and enjoys mentoring students of all levels.
