    Notes & Recommendations
    • - Review the lecture notes before each lecture. Bring a copy to lecture for note taking. Review them again shortly after the lecture.
  • - Read the chapter before lecture; study your lecture notes; reread the chapter; do the end-of-chapter & the graded homework.

  • - We will move along quickly in the class. It will be very difficult to obtain a good grade if you fall behind or if you do not attend lecture.

  • - Exams cover mainly lecture material; homework & lab questions are possible. There will be a quiz one or two lectures before each exam.

  • - No shorts, open toe shoes, or food allowed in the lab; full enclosure goggles are required.

  • - Master Dimensional Analysis & Equation problem solving techniques; use significant figures (SF) & show units for all problems.

    121 Grading

    2 Exams - 40% 2 Quizzes – 4% Final Exam - 30% Lab - 14 % HW - 12 %

    - Exam questions will cover lecture, text, and homework material. A few lab questions might be included in the tests. The questions will be approximately 70% multiple choice and 30% work out.

    - I will carefully review final course grades near the cut-off ranges.

    - Please feel free to interact with me any time about course questions.

    - Exam dates will be announced one to two weeks in advance – they will usually be

    one week after we finish the corresponding chapters.

    - Play careful attention to the numerous deadlines in this course.

    Course Objectives (prefix each with. “Students will”)

    Our Nuclear Heritage

    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.

    Scientists with a secret An article by Spencer R. Weart from Physics Today, February 1967. This tells the story of an informal agreement betweenf atomic scientists and the publishers of scientific journals to withold publication of information related to thefission of uranium and the production of plutonium until after World War II.

    Physics and Nuclear Arms Today This is a link to Google Books containing readings from Physics Today, 1976 to 1989, edited by David Hafemeister, containing selected reprints of articles on the effects of nuclear weapons, nuclear testing, nuclear defense, and nuclear proliferation

    How Nuclear Bombs Work. This is a link to the howstuffworks web site.

    The Story of the Atomic Bomb. 1934-1945, by James Richard Fromm. This is a link to the web site. This article is well illustrated with photos of most of the people involved.

    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.

    The Atomic Cafe This is a link to a film I show in class. The Atomic Cafe shows historical footage from the Trinity test, through the bombing of Hiroshima and Nagasaki, the atomic testing, post WWII propaganda, and footage from troop briefings and newsreels. This is a sometimes comical and often chilling about the cold war paranoia in the U.S. Normally, I interupt the film several times to add additional information not available in this film or other documentaries listed below. Even without the additional information, this is an important part of our atomic heritage. If the link, above, is not active here is a second link to the film on youtube (it may be preceded by an advertisement)

    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 1 and 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 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.

    Read the experiments before coming to class. If you prefer to work from your computer or tablet, you will still need to download data pages for your lab reports.

    Emission spectra of elements: These are links to web sites for emission spectra of elements. Note: Academic websites may only be available for limited time periods.

    A periodic table from University of Oregon. Click on an element to see the spectrum. Choose between absorption and emission spectra.

    Quicktime movies from Beloit College. Click on the absorption, emission, or combination spectrum shown to initiate spectra. Move the slide on the bottom of the spectrum to select elements. Note: Apple Quicktime needed (a free download)

    Spectroscopy: Element Identification and Emission Spectra. Contains an explanation of spectra with both selected flame spectra and element spectra following the explanation. This material was prepared by Dr. Walt Volland, Bellvue Community College.
