Chemistry Videos for Review of Topics

Khan Academy provides a number of videos on various subjects at no cost on YouTube. They are a not-for-profit organization with a mission of providing information. (They do ask for donations) The chemistry videos cover most of the topics for a high school or first-year college chemistry course. The videos are essentially lectures of up to about 15 minutes in length with limited notes being written on a black screen as one would write on a blackboard with some occasional pictures or tables. These were recommended by a student. I have only viewed portions of some videos and have found a few misconceptions. Use these videos with care.

Albert Einstein's Letters to President Franklin D. Roosevelt. Leo Szilard, a Hungarian physicist who left Germany after Hitler's rise to Power, feared that Germany's nuclear scientist might be able to make a "nuclear Bomb". He had Albert Einstein sign a letter to President Roosevelt which explained the possibility of a nuclear bomb and urged that the United States not allow a potential enemy to develop it first.

US Nuclear Tests: Nuclear tests from July 1945 to September 1992 – with web links.

Let's Make a Thermonuclear Device. In November 2001, British reporters searching through an abandoned "al-Qaida safe house" in Kabul, Afghanistan, found this document, and reported that they'd stumbled upon the terrorists' nuclear intentions. This information was published in a Nov. 15 article in the Times of London. In the article, journalist Anthony Loyd wrote that next to "physics and chemistry manuals devoted to molecular matter," he discovered this document on how to make a thermonuclear device. Marc Abrahams, a former editor of the Journal of Irreproducible Results, where the article originally appeared, said "Either there's one guy in the Taliban who had a sense of humor, or everyone was downloading everything on the Net that had the word 'thermonuclear' in it."

NOTE: My class presentation on nuclear chemistry includes a discussion on the atomic bomb and some of its applications (or misapplications), along with schematics of the two bombs used by the United States at the end of World War II. I will not use this web site as a forum to discuss whether it was right or wrong to unleash nuclear weapons on the world - that's history, and it's up to each individual to research the reasons for that ultimate decision. Much of the destruction and injury caused by the atomic bombs was suppressed by the U.S. government and classified until 1968, but still, only a small amount of material is publicly available in bits and pieces on the Internet. Remenber, only one country has ever used nuclear weapons in warfare. Few people, alive today, have witnessed the potential destruction that a single atomic bomb can produce. It is my belief that nuclear weapons must never be used again, for any reason, and that there should be a world-wide ban on all nuclear weapons.

What follows are links to three films about Hiroshima and Nagasaki:

A Tale of Two Cities, presented by the U.S. War Department is a Government film using Hiroshima and Nagasaki Stock Footage. It is presented as a newsreel-type of film.  (To play, click on the balloon on the play bar on the bottom of the screen.)

Hiroshima, Hirohito, & the Rising Sun, Part 1.  Hiroshima is a film by Rhawn Joseph, PhD.  Assembled from pre-bombing footage, atomic testing footage, and post-bombing footage. 

Hiroshima-Nagasaki, August,1945. Part 1and Part 2  is a compilation of silent black-and-white film footage of the ruins of Hiroshima and Nagasaki shot by Japanese cameramen of the Nippon Eiga She documentary unit before the U.S. occupation forces arrived in Japan.  This halted by the occupation, then ordered resumed under its supervisions. Later all footage was impounded, classified SECRET, and moved to the United States.

In 1968, Columbia University, learning about this material, applied to the U.S. Department of Defense for access to it. Apparently a declassification had recently taken place, and Columbia was permitted to duplicate the surviving 2 hours and 45 minutes of footage. The result was Hiroshima-Nagasaki, August 1945, the most widely shown film of the Hiroshima-Nagasaki holocaust, documenting the meaning of nuclear war. Hirishoma-Nagasaki, August 1945 (16 minutes, black and white) was produced by Erik Barnouw for the Columbia University Press and is available for purchase at The Robert Flaherty Film Seminar http://www.flahertyseminar.org/?sb=5&mb=4 . The complete 30-minute film is titled  "The Case of the A-Bomb Footage," and includes an introduction by Erik Barnouw, which traces the history of long-suppressed footage.
