A Lecture in Public Health: Health Status of the United States versus Other Nations
Stephen Bezruchka Senior Lecturer at the Departments of Health Services and Global Health of the University of Washington in Seattle talks about his article "The Hurrider I Go the Behinder I Get: The Deteriorating International Ranking of U.S. Health Status" which he wrote for the 2009 Annual Review of Public Health. Using graphics to illustrate his points Dr. Bezruchka describes how the United States has fallen to the 34th place in life expectancy after Cuba Chile and Denmark. He also emphasizes the deteriorating health of women as measured by their life expectancy which has dropped in 30% of U.S. counties between 1987 and 2007. Finally Dr. Bezruchka outlines his recommendations for improving health in the United States including creating awareness about the nation's low ranking among developed countries and investing more in early life.

A Lecture in Environment and Resources: Agroecology: A Review from a Global-Change Perspective
Dr. Thomas P. Tomich Director and W.K. Kellogg Endowed Chair in Sustainable Food Systems of the Agricultural Sustainability Institute at the University of California Davis and Committee Member of the Annual Review of Environment and Resources talks about his article "Agroecology: A Review from a Global-Change Perspective" which he co-wrote with another 15 authors from a variety of disciplines. In this lecture Dr. Tomich discusses the agricultural challenges brought on by a world population that could surpass nine billion individuals by 2050 as well as water scarcity climate change pests nitrogen prices and geopolitical factors. An important question will be how to feed nine billion people and do it in a sustainable way. He stresses the importance of approaching agroecology from an scientific perspective integrated across disciplines from economic and social sciences to entomology and genomics.
A Conversation with Roger Guillemin
Dr. Roger Guillemin Distinguished Professor at the Salk Institute for Biological Studies and Laureate of the 1977 Nobel Prize in Physiology or Medicine talks about his life and career with Dr. Greg Lemke Françoise Gilot-Salk Professor at the Salk Institute for the 2013 Annual Review of Physiology. Dr. Guillemin discusses his childhood and high school education in Dijon France and how he and his friends preferred to go underground at the end of their first year of medicine rather than be shipped to Munich to build weapons for the German army. After the war Dr. Guillemin practiced medicine then decided follow Hans Selye to his laboratory in Montreal. There he began the research in endocrinology that led him to make discoveries and lay the foundations of the study of brain hormones eventually winning the Nobel Prize.
A Conversation with Andreas Acrivos
Dr. Andreas Acrivos Albert Einstein Professor of Science and Engineering Emeritus at the Levich Institute located at the City College of New York talks about his life and career with his former student Dr. Eric S.G. Shaqfeh Professor of Mechanical Engineering at the Institute for Computational and Mathematical Engineering of Stanford University. Born in Greece to an affluent family his life took a definitive turn during the German occupation of Greece in the second World War. He moved to the United States to study Chemical Engineering with the plan of returning to his native country to build an industry. Instead he became an integral part of American academics and was instrumental in developing the Chemical Engineering programs at UC Berkeley Stanford University and City College of New York. Always pushing his research beyond the formal training he received he sought to attract the most talented and ambitious students and served as an example to many young Greeks who chose to follow in his footsteps.
Leidenfrost Dynamics: Supplemental Video 1
A supplemental video from the 2013 review by David Quéré "Leidenfrost Dynamics" from the Annual Review of Fluid Mechanics.
Water drops falling on a hot plate (at a temperature of 300°C). These drops are in the Leidenfrost state as shown by their shape (quasi-spherical) the absence of boiling and a very high mobility. Credits: Marc Fermigier Christophe Clanet and David Quéré.
Leidenfrost Dynamics: Supplemental Video 2
A supplemental video from the 2013 review by David Quéré "Leidenfrost Dynamics" from the Annual Review of Fluid Mechanics.
Hot steel ball (diameter of 15 mm) magnetically maintained in FC-72 a fluorinated liquid boiling at 56°C. For a ball temperature larger than the Leidenfrost temperature TL (130°C for this system) a film of vapor forms (inverse Leidenfrost phenomenon). This film drains upwards generating ripples and bubbles at the upper pole. After 30 s the ball temperature reaches TL which produces an explosive release of bubbles.

Leidenfrost Dynamics: Supplemental Video 3
A supplemental video from the 2013 review by David Quéré "Leidenfrost Dynamics" from the Annual Review of Fluid Mechanics.
Side view of a large Leidenfrost drop just above the threshold size of destabilization: A chimney of vapor rises at the center and makes the dome above the liquid. When this dome bursts a liquid torus transiently forms and closes which produces an eruption above the puddle. Spectacular oscillations follow. The movie is slowed down by a factor of 100. Credits: Dan Soto and Raphaële Thévenin.
Leidenfrost Dynamics: Supplemental Video 4
A supplemental video from the 2013 review by David Quéré "Leidenfrost Dynamics" from the Annual Review of Fluid Mechanics.
Top view of the destabilization of a large Leidenfrost drop: Above a threshold in size a chimney forms at the center of the drop. As it closes (and later reappears) the drop oscillates. Credits: Marc Fermigier Christophe Clanet and David Quéré.
Leidenfrost Dynamics: Supplemental Video 5
A supplemental video from the 2013 review by David Quéré "Leidenfrost Dynamics" from the Annual Review of Fluid Mechanics.
A Leidenfrost drop running on a plate with crenelations slows down on centimeter-size distances instead of meters on a flat solid. The distance between two crenels is 1.5 mm and the depth is 250 µm. The enhanced friction is attributed to the successive (soft) impacts of the bumps below the drop onto the sides of the crenelations. Credits: Guillaume Dupeux and Marie le Merrer.
Leidenfrost Dynamics: Supplemental Video 6
A supplemental video from the 2013 review by David Quéré "Leidenfrost Dynamics" from the Annual Review of Fluid Mechanics.
Combined videos showing the fall of a centimeter-size steel sphere at 25°C (on the left) 110°C (in the middle) and 180°C (on the right). At 110°C there is an intensive bubble release (this temperature is above the boiling point of liquid here FC-72 like in Supplemental Video 2). At 180°C there is a continuous vapor film (it is above the Leidenfrost temperature) which makes its final fall velocity much higher than in the other cases. The movie is slowed down by a factor 30. Credits: Ivan Vakarelski and Siggi Thoroddsen.
