The Oil Spill's Unseen Culprits and Victims
The Gulf oil spill dwarfs comprehension, but we know this much: it's bad. Carl Safina scrapes out the facts in this blood-boiling cross-examination, arguing that the consequences will stretch far beyond the Gulf -- and many so-called solutions are making the situation worse. Carl Safina's writing explores the scientific, moral and social dimensions of our relationship with nature. This speech was given in June of 2010. Run time 19:56.
In this video, Sal Khan uses toothpicks and houses to solve this logic problem. Mr. Khan uses the Paint Program (with different colors) to illustrate his points. The viewer may wish to open the video to 'full screen' as there is a lot of writing on a small black screen. Sal Khan was the recipient of the 2009 Microsoft Tech Award in Education.

Columns: Experimenting with Paper Cups
Columns, vertical structural elements that are strong in compression, are good at propping things up. In this video segment adapted from ZOOM, the cast uses paper cups to illustrate what makes columns strong and why they sometimes collapse. By filling the cups with sand, they also show that even hollow columns of a weak material like paper can be made surprisingly strong. Closed captioning included. Run time 03:03.

Little Brain, Big Journey
The Rufous hummingbird is a small wonder that, with respect to body size, migrates farther than any other creature on earth. The brightly colored, feisty bird breeds from southern Alaska to northern California and then spends the winter in Mexico. Though their brains are approximately the size of a grain of rice, Rufous hummingbirds have an excellent memory for locating flowers from year to year. In this video segment from Nature, learn about the little brain and big journey of the Rufous humm

Calisphere Themed Collection - 1870-1900: Closing of the Frontier: Everyday Life and People
The images in this topic show how Californians in the late 19th century worked and played. Many of these photographs reflect the manual labor (mining, logging, agriculture) and services (like barber shops and grocery stores) that supported the rapid growth of cities and towns. As they do today, people spent their free time doing quiet activities like painting, enjoying themselves outdoors, riding bicycles and camping.
Calisphere Themed Collection - 1780-1880: California in Transition: Everyday Life, 1850s-1890s
The images in this topic depict everyday life in California during a time of explosive growth. Even as the state’s mix of cultures became more interconnected, they still managed to maintain and express their unique identities.

Calisphere Themed Collection - 1780-1880: California in Transition: Rich Resources
These images show the importance of both California's natural and human resource potential to the state’s development and subsequent wealth. Natural resources like water, lumber, and oil — along with human-driven resources like transportation, agriculture, and technology — have all contributed to California's growth. These natural resources drew many different ethnic groups to the state: human resources that would construct railways and aqueducts, plant crops and harvest them, strike it ri
