Bill writes:
On October 15, 1582 AD, according to the Julian calendar, Pope Gregory XIII introduced a new calendar, the Gregorian or Western calendar. Thus, on November 7, 1492, the day of the Ensisheim fall according to the Julian calendar, the very same Ensisheim meteorite also fell on November 16, 1492 according to the Gregorian calendar. (So much for Einstein’s simultaneity. https://physicstoday.scitation.org/doi/10.1063/1.2774101) For the curious, both dates are Wednesdays.
The bulk samples below were obtained from Anne Black and the thin section below was obtained from Russ Kempton, who acquired it from Heinrich Wänke several weeks following a conference held in Prague. Note the elliptical cover glass.
Adding to the history surrounding some the individuals involved for the thin section:

Paul, I forgive the Programmer; I too have made four mistakes, so far, in my old age. When mentioning this in class, one student said that she notched her pencil and kept count of my errors. A pencil with an eraser and wood filler bought her silence. |
