• The Stereochemistry of Boats and Chairs

    • Hauser, Stephan E.    12/01/00

    I would like to add some observation to the intriguing notion of cyclohexane mentioned in Robert Ausubel's response to "Boats and Deckchairs". One might add that the terms "boat" and "chair" are international standard in teaching the peculiarities of cyclohexane in stereochemistry. We find the terms "Boot" (boat) or "Wanne" (tub) and "Sessel" (chai

    • Latamie, Marc    12/01/00

    Stephen Jay Gould's text is very interesting and full of pleasant "interactive consonants." Though it seems important to add Frantz Fanon's "R- assimilationist" so to speak, to the discussion. Fanon actually devoted part of his book "Black Skin, White Mask" (1952) to the importance of language and pronunciation. A doctor and trained psychoanalyst,

    • Naumann, Francis M.    05/01/00

    Dear Dr. Gould; When I saw the headline of the article you and your wife wrote in the December-JanuaryNatural History, as a chemist, one thought came to my mind: cyclohexane. As I read the article, I realized that the connection may be germane. When learning organic chemistry, the structures initially are written as two-dimensional. Only later

    • Schmitt, James L.    05/01/00

    Dear Drs. Gould and Shearer, Thank you for your interesting article in the December issue of Natural History. It led me to an alternative interpretation of his boat/deckchair illusion using the notion of a cross-section, which is implicit in the passage from Flatland that you quoted. Imagine three spheres in space. One can obtain a 2-dimensiona

    To the Editor: In their essay on a note by Marcel Duchamp about the fourth dimension (Natural History, 12/99-1/00), Stephen Jay Gould and Rhonda Roland Shearer emphasize the fact that no other previous Duchamp scholar has ever noticed that the text of this particular note relates to the image of three boats in a landscape that appears on its ver

    • Ausubel, Robert    05/01/00

    Dear Professors, I am only vaguely familiar with the concept of the fourth dimension, and your fascinating essay in the January Natural History will encourage me to investigate it. I believe that you are away of some points that I would like to make and ignored them for brevity's sake, but let's see. One of the overriding proposals of the essay
