NASA | Landsat: Making a Difference, One User At A Time
The Landsat Data Continuity Mission will continue and improve upon the 40-year-old Landsat program. This video examines two uses of Landsat data to monitor agriculture. Both wineries and timber companies rely on Landsat data to check whether their vines and trees are getting enough (or too much) water and fertilizer. The small resolution and regular repeat cycle of the satellite data is crucial to monitoring the health of their crops. (03:44)
Assessment in Math and Science-That Would Never Work Here!
Workshop 6. That Would Never Work Here!; Seeing Assessment Reform in Action, Part I (90 min.)
'What does assessment reform actually look like? This workshop follows the stories of Barbara, a math teacher in Whittier, California, and Scott, a science teacher in Louisville, Kentucky, as they share how they are incorporating assessment into their teaching. Emphasis will be placed on the colleague support structure — teachers sharing ideas with and getting help from other teachers. C
5.05 Principles of Inorganic Chemistry III (MIT)
This course covers the principles of main group (s and p block) element chemistry with an emphasis on synthesis, structure, bonding, and reaction mechanisms.
5.13 Organic Chemistry II (MIT)
5.13 is an intermediate organic chemistry course that deals primarily with synthesis, structure determination, mechanism, and the relationships between structure and reactivity emphasized. Special topics in organic chemistry are included to illustrate the role of organic chemistry in biological systems, medicine, and in the chemical industry.
HST.930J Social Studies of Bioscience and Biotech (MIT)
In this course, social, ethical and clinical issues associated with the development of new biotechnologies and their integration into clinical practice is discussed. Basic scientists, clinicians, bioethicists, and social scientists present on the following four general topics: changing political economy of biotech research; problems associated with the adaption of new biotechnologies and findings from molecular biology for clinical settings; the ethical issues that emerge from clinical research

Injection-moulded polystyrene ruler
The colours in the image are the result of birefringence and relate to the residual strain in the polystyrene. The pattern of strain is indicative of the flow of material during the injection process and it highlights the injection point (known as a 'gate') at the end of the ruler; the molecular alignment is greatest near this point. Towards the edges of the ruler and along its length, the material becomes more relaxed and as the molecular alignment falls, the retardation of light is less. If
This is a three-minute clip from the 'Clash of the Continents: End of Eden.' "When a volcanic rift occurs, the Earth comes back to life with a vengeance! Intense lava flow can mean intense natural growth." This video uses computer animation and recorded live images for demonstration. (03:07)
Atacama Pathfinder EXperiment (APEX)
The Atacama Pathfinder EXperiment (APEX) is a collaboration between the Max Planck Institut für Radioastronomie (MPIfR), Onsala Space Observatory (OSO) and the European Southern Observatory (ESO) to construct and operate a modified Atacama Large Millimetre Array (ALMA) prototype antenna as a single dish on the high altitude site of Llano Chajnantor (Chile). It can be used to study cold dust and gas in the Milky Way and in distant galaxies, to trace the thermal continuum emission and analyse hig
Fracture surface in a liquid crystalline polymer
Above their melting point, liquid crystalline polymers exhibit a mesophase within which, although able to flow and are not arranged in a crystal, they exhibit long range orientational order. This molecular alignment can be exploited to make high strength and stiffness fibres such as Kevlar, or even mouldable thermotropics such as Vectra. Molecular alignment can also be controlled by an external applied field; a property exploited in liquid crystal displays. This specimen has not had a magneti

Video Brain Teaser #56
Videos that provide viewers with brain teasers/mental puzzles. These may consist of problems dealing with the arrangement of matchsticks, coins, and other items. May include pencil drawing games, optical illusions, hidden images and "Find the Twin" problems.
Edge Show 92 - Ned Pyle and changes to DFS in Windows Server 2012 R2 | Edge In this episode of the Edge Show, Rick sits down with Ned Pyle - Senior PM on the File Server team to talk about changes to DFS in Windows Server 2012 R2 and how we've changed the staging and cloning capabilities. You might remember Ned from the "Ask DS" blog where he was a main contributor for the Directory Services team while working as a top level support engineer. Simon and Rick cover off some interesting bits from the interwebs, including:

EINSTEIN'S MESSENGERS, LIGO AND THE SEARCH FOR GRAVITY WAVES
By: nsf Einstein's Messengers is an Award-winning 20-minute documentary on LIGO, NSF's Laser Interferometer Gravitational Wave Observatory. The video examines how LIGO is spearheading the completely new field of gravitational wave astronomy and opening a whole new window on the universe. It explains how LIGO's exquisitely sensitive instruments may ultimately take us farther back in time than we've ever been, catching, perhaps, the first murmurs of the universe in formation. Above all, Einstein's

Wyndham Worldwide’s Stephen Holmes on the Changing Nature of Leisure Travel
After nearly 20 years in the hospitality industry, Wyndham Worldwide chairman and CEO Stephen Holmes says he has seen several "shifts" in the sector -- from the way that consumers plan their vacations to what they expect to find when they stay at a hotel. The most recent catalyst for change has been the global economic downturn. Wyndham -- one of the world's largest hospitality companies -- has weathered that storm, and has actually grown since the recession began. In an interview with Knowled
7.342 Cancer Biology: From Basic Research to the Clinic (MIT)
This course is one of many Advanced Undergraduate Seminars offered by the Biology Department at MIT. These seminars are tailored for students with an interest in using primary research literature to discuss and learn about current biological research in a highly interactive setting. In 1971, President Nixon declared the "War on Cancer," but after three decades the war is still raging. How much progress have we made toward winning the war and what are we doing to improve the fight? Unde
34 Simple Machines Demonstrate a Transfer of Energy
Imagine the most complicated process you could go through to simply pour a glass of milk. Then multiply that by 10. The image in your mind is probably approaching the level of complexity the ZOOM cast members achieved with their milk-pouring machine. Watch as they demonstrate all 34 steps in this video segment adapted from ZOOM. This would be a great addition to a lesson on transfer of energy or types of potential energy. There are several examples of gravitational energy as well as elasti
