Video - Stefan W. Hell (2015) : Optical Microscopy: the Resolution Revolution Throughout the 20th century it was widely accepted that a light microscope relying on conventional optical lenses cannot discern details that are much finer than about half the wavelength of light (200-400 nm), due to diffraction. However, in the 1990s, the viability to overcome the diffraction barrier was realized and microscopy concepts defined, that can resolve fluorescent features down to molecular dimensions. In this lecture, I will discuss the simple yet powerful principles that allow neutralizing the limiting role of diffraction1,2. In a nutshell, feature molecules residing closer than the diffraction barrier are transferred to different (quantum) states, usually a bright fluorescent state and a dark state, so that they become discernible for a brief period of detection. Thus, the resolution-limiting role of diffraction is overcome, and the interior of transparent samples, such as living cells and tissues, can be imaged at the nanoscale.
Engineering Anomalies Research The Princeton Engineering Anomalies Research (PEAR) program, which flourished for nearly three decades under the aegis of Princeton University’s School of Engineering and Applied Science, has completed its experimental agenda of studying the interaction of human consciousness with sensitive physical devices, systems, and processes, and developing complementary theoretical models to enable better understanding of the role of consciousness in the establishment of physical reality. PEAR has now incorporated its present and future operations into the broader venue of the ICRL, a 501(c)(3) not-for-profit research organization, in addition to Psyleron—a company that provides Random Event Generator devices to enable the continued exploration of PEAR’s findings by the general public and research communities. On the accompanying menu of pages we have attempted to sketch the substance, spirit, and findings of this scholarly endeavor.
100 Free Online Ivy League Courses By Alisa Miller Even those without top notch grades can now go to Ivy League schools. With the the availability of open courseware classes coming out of some of the finest schools in America, the range of subjects is astounding. If you have ever wondered about the beginnings of Hip Hop, wanted to learn a new language, would like to create a film for social change, or are interested in learning about robotics while playing with Legos, then these courses are right up your alley.
Oral Presentation Skills What information should you give in your speech? All your information should support purpose. In most cases you will have to limit the content, as time is usually precious!

Center for African American Studies We thank the supportive and generous Princeton University alumni who recognize the important work of the Center for African American Studies. On March 11, we dedicated the Hobson-Rogers Seminar Room and the Barfield-Johnson Seminar Room of Stanhope Hall, our historic home. Professor Naomi Murakawa joins the faculty at the Center for African American Studies as an associate professor of African American Studies. Universities See our list of the top schools offering free courses online. Learn about what types of courses are available to find the school and courses that are right for you. Online Courses for Credit Plenty of free resources are available online for students who want to learn a new topic, but these free options don't generally lead to college credit. Students who want to earn college credit might want to look for online options that charge a small fee in exchange for access to online lessons. These fee-based courses can help students earn alternative forms of college credit.
See What I Mean? Visualizing in Science > Science for the Public December 11, 2012 Belmont Media Center Bang Wong Creative Director, Broad Institute of MIT and Harvard We depend on visual representation for science concepts and data to make this kind of information more comprehensible. Science illustration is art in the service of science. A Book Apart, Content Strategy for Mobile foreword by Paul Ford You don’t get to decide which platform or device your customers use to access your content: they do. Mobile isn’t just smartphones, and it doesn’t necessarily mean you are on the move. It’s a proliferation of devices, platforms, and screensizes — from the tiniest “dumb” phones to the desktop web. How can you be sure that your content will work everywhere, all the time? Karen McGrane will teach you everything you need to get your content onto mobile devices (and more).
Brief Answers to Cosmic Questions Structure of the Universe Does the Universe have an edge, beyond which there is nothing? Are the galaxies arranged on the surface of a sphere? Why can't we see the whole universe? UC Irvine Water is the economic, social, and physical lifeblood of humanity, providing the bases for agriculture, industry, transportation, energy production, and life itself. Despite its importance, alarming signs suggest that there are looming threats to this vital resource. The World Resources Institute contends that the world's thirst for water is likely to become one of the most pressing issues this century due to population growth, drought, and climate change. The World Bank reports that many developing nations already face a crisis from intensive irrigation, urbanization, diminishing supplies, and deteriorating infrastructure; and, UNESCO predicts as many as 7 billion people in half the world’s countries will face shortages of potable water by 2050.
