Heart and Circulatory System - How They Work
The video uses computer animation to give an overview of the organs inside the circulatory system.  The video includes a transcript that begins with "Your heart is a pump. It's a muscular organ about the size of your fist and located slightly left of center in your chest.
Your heart is divided into the right and the left side. The division protects oxygen-rich blood from mixing with oxygen-poor blood.
Together, your heart and blood vessels comprise your cardiovascular system, whic

Military and Economic Mobilization
In response to growing threats from the Axis Powers during the late 1930s, the United States Congress passed a series of Neutrality Acts and embarked on a more aggressive military preparedness program. In 1938, Congress announced that it sought "a Navy second to none," and doubled the tonnage of combat vessels two years later. The nine battleships and eleven Essex class aircraft carriers that were part of that build-up, however, were not commissioned until 1943. By the summer of 1941, the milita

Blood Vessels Help Tumors Grow
This video segment, adapted from NOVA, features cancer researcher Dr. Judah Folkman and describes his approach to proving a new idea he had about how tumors grow inside the body. His idea focuses on angiogenesis, the formation of new blood vessels. Dr. Folkman designed experiments to test his central hypothesis and thus prove the support mechanism behind tumors. Closed captioning included.  Run time 05:07.

Polio pt 1
Content: Poliomyelitis is a viral infection of the intestinal tract. Most cases of polio were mild--headache, fever, sore throat, and depression--with the patient usually recovered within three or four days. In fewer and more serious cases, the virus penetrates the stomach and intestinal tract, enters the lymphatic system, then the bloodstream, and then attacks the motor nerve cells of the spinal cord; if the nerve damage is severe, paralysis will result. Occurring most frequently in children, p

18 - Imperfect information: information sets and sub-game perfection
We consider games that have both simultaneous and sequential components, combining ideas from before and after the midterm. We represent what a player does not know within a game using an information set: a collection of nodes among which the player cannot distinguish. This lets us define games of imperfect information; and also lets us formally define subgames. We then extend our definition of a strategy to imperfect information games, and use this to construct the normal form (the payoff matri

Al-90 wt% Cu (bronze)
This is a copper-aluminium bronze containing 10 wt% aluminium. A small amount of iron is often added to act as a grain refiner to improve the mechanical properties. Alloys with more than 8 wt% aluminium solidify as the β phase. Below about 930°C, Widmanstätten α phase precipitates. At the eutectoid temperature (565°C) the remaining β decomposes to a lamellar eutectoid of α and β. Rapid cooling from the high temperature β phase can form martensite instead of Widmanstätten α.

Battlefield: The Battle of Midway (1/12)
In June 1942, the most decisive naval battle of WWII was fought between the United States of America and the Japanese empire. Waged entirely of aircraft carriers, hundreds of miles apart, the Battle of Midway was the first major fleet encounter in which the ships on each side never came within visual range of enemy vessels. Victory or defeat depended not on the big guns of battleships, but on the carrier born bombers and torpedo bombers flying over vast tracks of ocean to seek and destroy their
