    Women were asked to look at a trio of sketches of men in various settings, and to say where they’d prefer to find their ideal man: in camp chopping wood, in a studio painting a canvas, or in a garage working a pillar drill. 1400 Series computer, which then spit out your matches: five blue cards, if you were a woman, or five pink ones, if you were a man.


    Famous carbon dating examples

    Willard Libby (1908–1980), a professor of chemistry at the University of Chicago, began the research that led him to radiocarbon dating in 1945.

    He was inspired by physicist Serge Korff (1906–1989) of New York University, who in 1939 discovered that neutrons were produced during the bombardment of the atmosphere by cosmic rays.

    As a relative dating method, it can determine the relative age of specimens, but cannot provide a calendrical date unless the fluoride chronology is calibrated with an absolute dating method.

    Bones are primarily composed of the mineral calcium hydroxy apatite.

    The amount of C-14 in the atmosphere settles into an equilibrium where creation of new atoms is equal to the decay of old atoms.

    A January 20, 2005 article in the scholarly, peer-reviewed scientific journal Thermochimica Acta (Volume 425, pages 189-194, by Raymond N.

    Rogers, Los Alamos National Laboratory, University of California) makes it perfectly clear: the carbon 14 dating sample cut from the Shroud in 1988 was not valid.

    Korff predicted that the reaction between these neutrons and nitrogen-14, which predominates in the atmosphere, would produce carbon-14, also called radiocarbon.

    Libby cleverly realized that carbon-14 in the atmosphere would find its way into living matter, which would thus be tagged with the radioactive isotope.
