  • The Cosmos - Before the Big Bang
    From issue 2601 of New Scientist magazine, 28 April 2007, page 28-33 The cosmos - before the big bang How did the universe begin? The question is as old as humanity. Sure, we know that something like the big bang happened, but the theory doesn't explain some of the most important bits: why it happened, what the conditions were at the time, and other imponderables. Many cosmologists think our standard picture of how the universe came to be is woefully incomplete or even plain wrong, and they have been dreaming up a host of strange alternatives to explain how we got here. For the first time, they are trying to pin down the initial conditions of the big bang. In particular, they want to solve the long-standing mystery of how the universe could have begun in such a well- ordered state, as fundamental physics implies, when it seems utter chaos should have reigned. Several models have emerged that propose intriguing answers to this question. One says the universe began as a dense sea of black holes. Another says the big bang was sparked by a collision between two membranes floating in higher-dimensional space. Yet another says our universe was originally ripped from a larger entity, and that in turn countless baby universes will be born from the wreckage of ours. Crucially, each scenario makes unique and testable predictions; observations coming online in the next few years should help us to decide which, if any, is correct. Not that modelling the origin of the universe is anything new.

  • Atheism Is Inconsistent with the Scientific Method, Prizewinning Physicist Says - Scientific American

Credit: Eli Burakian Dartmouth College https://www.scientificamerican.com/article/atheism-is-inconsistent-with-the-scientific-method-prizewinning-physicist-says/ 1/10 8/4/2019 Atheism Is Inconsistent with the Scientific Method, Prizewinning Physicist Says - Scientific American ADVERTISEMENT Marcelo Gleiser, a 60-year-old Brazil-born theoretical physicist at Dartmouth College and prolific science popularizer, has won this year’s Templeton Prize. Valued at just under $1.5 million, the award from the John Templeton Foundation annually recognizes an individual “who has made an exceptional contribution to affirming life’s spiritual dimension.” Its past recipients include scientific luminaries such as Sir Martin Rees and Freeman Dyson, as well as religious or political leaders such as Mother Teresa, Desmond Tutu and the Dalai Lama. Across his 35-year scientific career, Gleiser’s research has covered a wide breadth of topics, ranging from the properties of the early universe to the behavior of fundamental particles and the origins of life. But in awarding him its most prestigious honor, the Templeton Foundation chiefly cited his status as a leading public intellectual revealing “the historical, philosophical and cultural links between science, the humanities and spirituality.” He is also the first Latin American to receive the prize.

    13 December 2018 Dear Participants: It is my honor to welcome you to the 15th topical physics conference in the “Miami” series --- a meeting that continues a sixth decade of physics conferences held in south Florida. This year’s meeting is dedicated to the memory of Peter Freund. Peter was a good friend to me and many others at this meeting. He was a frequent participant and he gave strong support for these conferences. Moreover, the current particle theory group at the University of Miami was created in the late 1980s largely due to Peter’s enthusiastic endorsement. Before the current series began in December 2004, the “Coral Gables conferences” were organized by University of Miami faculty from January 1964 to December 2003, often assisted by many faculty from other institutions including many of the organizers of this meeting. In particular, Sydney Meshkov has helped to organize and has attended almost all of these meetings since they began over 50 years ago. His participation again this year continues this remarkable tradition. It is also traditional for these meetings to try to accommodate most if not all requests to speak without having parallel sessions. Once again that will be the case, and once again this year the conference program and other useful information will not be printed and distributed in a binder. This information will only be available, in its entirety, online. See https://cgc.physics.miami.edu/Miami2018.html If you must have a printed copy of the entire program, as well as the other useful information, here is a printer friendly source, https://cgc.physics.miami.edu/2018ConferenceBooklet.pdf If you have any special requirements for your talk, or if you have any questions that the hotel staff cannot answer, please ask any attending local member of the organizing committee, in particular, Jo Ann Curtright (cell phone number 786-200-1480), Thomas Curtright (cell phone number 305-793-4637), as well as Diego Castano, and Stephan Mintz.

Most of the work has involved the study of the very early Universe—inflation, dark matter, dark energy, cosmological/astrophysical limits on particle properties, baryogenesis, phase transitions, axions, etc. An additional area of my activity is science education, particularly with regard to education for the general public. This activity includes writing and lecturing on cosmology.
