Organic Chemistry for the YouTube Generation

No matter how long they pore over their lab manuals, students feel anxious when they step into a science laboratory. Now a series of dynamic videos created by undergraduate students at the University of California, San Diego is helping them relax and focus on what really matters—the science behind the experiment.
“Students can’t concentrate on concepts when they are stressed about the technical details of performing an experiment,” said Haim Weizman, a lecturer in U.C. San Diego’s Department of Chemistry and Biochemistry, who spearheaded the video project. “By helping them prepare for the lab, the videos allow students to concentrate on the molecules and see the beauty of what is happening.”

Over the last few months, the videos, which can be viewed here have been downloaded more than 15,000 times from YouTube and SciVee, a website where scientists can trade research techniques. SciVee was developed by Phillip Bourne, a professor of pharmacology at UCSD.

Each video is approximately five to seven minutes long and features a student demonstrating a critical procedure in organic chemistry, such as the purification of a substance by distillation or recrystallization. Students have difficulty visualizing how to perform such procedures from the instructions in the laboratory manual alone.

About Environmental science

Environmental science is the study of interactions among physical, chemical, and biological components of the environment. Environmental Science provides an integrated, quantitative, and interdisciplinary approach to the study of environmental systems.

Environmental Scientists monitor the quality of the environment, interpret the impact of human actions on terrestrial and aquatic ecosystems, and develop strategies for restoring ecosystems. In addition, environmental scientists help planners develop and construct buildings, transportation corridors, and utilities that protect water resources and reflect efficient and beneficial land use. to the interdisciplinary nature of environmental science, teams of professionals commonly work together to conduct environmental research or to produce Environmental Impact Statements, as required by the U.S. National Environmental Policy Act (NEPA) or under state laws. Other professional organizations engender work in environmental science and aid in communication among the diverse sciences.

Since most environmental issues deal with human activities, study of economics, law and social sciences are often applied in conjunction with Environmental Science.

History of olympics

"The Olympics" redirects here. For other uses, see Olympics (disambiguation).

For the 2008 Olympic Games occuring in Beijing, see 2008 Summer Olympics.

The Olympic Games^[1] is an international multi-sport event. The original Olympic Games (Greek: Ολυμπιακοί Αγώνες; [Olympiakoi Agones] (help·info)) were first recorded in 776 BC in Olympia, Greece, and were celebrated until AD 393.^[2] Interest in reviving the Olympic Games proper was first shown by the Greek poet and newspaper editor Panagiotis Soutsos in his poem "Dialogue of the Dead" in 1833.^[3] Evangelos Zappas sponsored the first modern international Olympic Games in 1859. He paid for the refurbishment of the Panathenian Stadium for Olympic Games held there in 1870 and 1875.^[3] This was noted in newspapers and publications around the world including the London Review, which stated that "the Olympian Games, discontinued for centuries, have recently been revived! Here is strange news indeed ... the classical games of antiquity were revived near Athens."^[4]

The International Olympic Committee was founded in 1894 on the initiative of a French nobleman, Pierre Frédy, Baron de Coubertin. The IOC has become the heart of the "Olympic Movement," a conglomeration of sporting federations that are involved in the organization of the Games. As the Olympic Movement has grown so have the profile and complexity of the Games. Participation in the Games has increased to the point that nearly every nation on earth is represented. With the proliferation of satellite communications, the internet, and the continuing trend towards globalization, the Olympics are consistently gaining supporters.^[5] This growth has created numerous challenges, including political boycotts, the use of performance enhancing medications, bribery of officials, and terrorism.

Despite these challenges the Olympics have continued to thrive and flourish. Each successive Games attempts to add more events in order to keep up with the ever-evolving advance of athletic expression around the world. The 2008 games in Beijing comprise 302 events in 28 sports.^[6] The most recent Winter Olympics in 2006 featured 84 events in 7 sports.^[7] While the Olympic Games do continue to evolve, they also encompass many rituals that were established during their infancy in the late 19th and early 20th century. Most of these traditions are on display during the Opening and Closing ceremonies, and the medal presentations. For its part, the Olympic Movement has made considerable progress in fostering participation among as many nations as wish to compete, as well as focusing on the Olympic motto: Citius Altius Fortius - Faster, Higher, Stronger.

College Friends go to Olympics

Three college friends, one each from the Universities of Oxford, Cambridge and Loughborough, decided to pool their funds and go to the Olympics in Barcelona. The airfare and hotel rates ate up most of their money so they didn't have enough to get into the stadium to see the events.

So they stood around the gate, watching all the other people get in and then noticed that some people didn't have to pay. Whenever an athlete passed the guard with his (or her) equipment, the guard would simply nod and let them through. So the three visitors quickly trotted off to a nearby hardware shop and came back to try to get in.

The Oxford student walked up to the guard and gestured at the long pole he carried. "Pole vaulting," he said, and the guard waved him through.

The Cambridge student, having rigged up a ball to a length of chain, approached the guard next and showed of his wares. "Hammer throwing," he said, and the guard shrugged and waved him through.

The catering student from Loughborough came last, with a roll of chain link on his shoulder. "Fencing."
