    Lecture: Investigation of Multi-frequency Raman Generated Spectra

    Location: 

    Physics Department, Jefferson 250, 17 Oxford Street, Cambridge

    This lecture is part of the 2019 Loeb Lectures in Physics, delivered by Donna Strickland, Professor, Department of Physics & Astronomy, University of Waterloo; Nobel Laureate, Physics 2018

    Since the advent of lasers, many different nonlinear optical techniques have led to shorter, higher-intensity pulses. University of Waterloo is studying Multi-frequency Raman generation (MRG), which efficiently generates a large number of Raman orders spanning the spectral region from the infrared to the ultraviolet. The bandwidth of the Raman orders is sufficient to generate...

    Lecture: From Nonlinear Optics to High-Intensity Laser Physics

    Location: 

    Physics Department, Jefferson 250, 17 Oxford Street, Cambridge

    This lecture is part of the 2019 Loeb Lectures in Physics, delivered by Donna Strickland, Professor, Department of Physics & Astronomy, University of Waterloo; Nobel Laureate, Physics 2018

    The laser increased the intensity of light that can be generated by orders of magnitude and thus brought about nonlinear optical interactions with matter.  Chirped pulse amplification, also known as CPA, changed the intensity level by a few more orders of magnitude and helped usher in a new type of laser-matter interaction that is referred to as high-intensity laser physics...

    Twins in Space

    Location: 

    Radcliffe Institute for Advanced Study, Knafel Center, 10 Garden Street, Cambridge

    Spaceflight poses unusual stressors to the human body. To ensure that astronauts can perform under daunting conditions, NASA investigators have been studying the effect of long-duration spaceflight on crew members. This lecture will present the findings of the NASA Twins Study, which evaluated twin astronauts in different environments for one year: one in space and one on Earth.

    Early Science from the Transiting Exoplanet Survey Satellite (TESS)

    Location: 

    60 Garden Street, Phillips Auditorium, Cambridge, MA 02138

    Sam Quinn, Postdoctoral Research Fellow, Smithsonian Astrophysical Observatory

    NASA's Transiting Exoplanet Survey Satellite (TESS) began science operations in July 2018, and over the next two years will survey most of the sky in search of small planets transiting the nearest stars, the brightness of which enables studies of planetary compositions and atmospheric properties. These will likely be the planets on which we focus our search for life through the detection of biosignature gases in the planets' atmospheres. However, TESS is not just an exoplanet mission; by monitoring...

    Exhibition Opening: Measure

    Location: 

    Radcliffe Institute for Advanced Study, Knafel Center, 10 Garden Street, Cambridge, MA 02138

    Anna Von Mertens is an exhibited artist who uses the structures of quilting and drawing to explore the frontiers of human understanding. Her new exhibition "Measure" explores the life and work of Henrietta Leavitt, one of the women “computers” hired to study glass-plate astronomical photographs at the Harvard College Observatory a century ago. Leavitt’s findings provided a unit of measurement for galactic distances. Reimagined in meticulous stitches and intricate graphite marks, Von Mertens examines our current understanding of the size and shape of...

    The Secret Lives of Roots

    Location: 

    Hunnewell Building, Arnold Arboretum, 125 Arborway, Jamaica Plain, MA 02130

    The Arnold Arboretum is full of spectacular specimens from around the world that any visitor will appreciate. However, what they observe is only half the story. How a tree uptakes water and nutrients, stays grounded in place, stores energy, and sometimes even propagates itself, is all thanks to its roots. Join horticulturists Andrew Gapinski and Conor Guidarelli as they unearth these questions and more during an exclusive look into the extraordinary world of roots.

    Next in Evolution

    Location: 

    Radcliffe Institute for Advanced Study, Knafel Center, 10 Garden Street, Cambridge, MA 02138

    The Next in Science series provides an opportunity for early-career scientists whose creative, cross-disciplinary research is thematically linked to introduce their work to one another, to fellow scientists, and to nonspecialists from Harvard and the greater Boston area. The focus of this year’s program is in the study of evolution. In this program, two leading researchers will explore the genetic impact of Neanderthal interbreeding with modern humans and consider how people migrated, adapted, and mixed over the course of human history. Two...

    The Undiscovered

    Location: 

    Radcliffe Institute for Advanced Study, Knafel Center, 10 Garden Street, Cambridge, MA

    To paraphrase Louis Pasteur, sometimes luck favors the prepared mind, as when Alexander Fleming discovered penicillin by noticing that mold growing accidentally in his lab seemed to kill bacteria. This 2018 Radcliffe Institute science symposium will focus on how scientists explore realities they cannot anticipate. Speakers from across the disciplines of modern science will present personal experiences and discuss how to train scientists, educators, and funders to foster the expertise and open-mindedness needed to reveal undiscovered aspects of the world around us.

    Quantum Tools to Explore the Universe…and Help Life on Earth

    Location: 

    60 Garden Street, Phillips Auditorium, 60 Garden St, Cambridge, MA 02138

    At the Center for Astrophysics, we exploit quantum physics to advance the state-of-the-art in measurement and imaging, and then apply these tools to search for Earth-like planets around other stars and probe the nature, history, and fate of the Universe. Sometimes, these quantum tools can also be applied to down-to-Earth problems — ranging from health to navigation.

    Saving Coral Reefs in the Florida Keys

    Location: 

    Geological Lecture Hall, 24 Oxford Street, Cambridge MA

    James W. Porter, Josiah Meigs Distinguished Professor Emeritus, Odum School of Ecology, University of Georgia

    Coral reefs support more than a quarter of all marine life, yet many are critically endangered. In the Florida Keys, the once common elk horn coral (Acropora palmata) has experienced steep declines since the 1970s. Preliminary blame was attributed to global warming and coral bleaching, but in fact, a human bacterial pathogen associated with a wide range of serious infections was the culprit. James Porter will discuss how Key West residents are saving these reefs...
