![]() ![]() The pdf version of my English translation was kindly prepared by Cren Frayer at the NASA/IPAC Extragalactic Database (NED), also available at NED's Level5 repository since June 2017 (). Doubts on the meaning of the original phrasing are given in square brackets at a few places where they occur. ![]() The translation is as literal as possible, and annotations on the translation of certain terms are given. Now, 84 years later, with 1000+ radial velocities measured for Coma cluster members, Coma's velocity dispersion is very close to that found by Zwicky. Zwicky's conclusion is based on the velocity dispersion of only seven galaxies in the Coma cluster of galaxies. This paper is usually cited as the first evidence for dark matter ("dunkle Materie", not "missing matter"). Below are a few photos - many of the ones I took are not very good.English and Spanish translations are provided for Fritz Zwicky's seminal article on "The Redshift of Extragalactic Nebulae", published in German in Helvetica Physica Acta in 1933. I would have liked to seen more of the coins in the collection, but space is limited and there are many other items in America's history that compete for space. This particular day it appeared to be very a very close race.Īll in all - it was a nice day and I am glad that I was able to make the journey to see the collection. One panel had two large glass jars set up for donations asking you to donate th whether you want to save the cent or do away with it. This exhibit was nicely laid out and was more camera friendly. ![]() The east wing's exhibit was the story on money. There were many gold coins that drew my interest along with the three 1804 dollars. Ignoring those disappointments, the exhibt was nicely laid out and I enjoyed seeing some of the rarities that I would probably never see anywhere else. ![]() I was also a bit disappointed that many of the coins appeared to be cleaned. All of the sovereigns donated were melted and made into U.S. smithson donated over 100,000 sovereigns to establish the Smithsonian in an attempt to increase and diffusion of knowledge. I was a bit disappointed that the exhibit did not show one of the two 1838 Sovereigns that are in the National collection that were like the ones donated by James Smithson. The exhibit is broken into two small rooms, one in the east and west wings of the National History Museum. The exhibit was recently renovated and is not easily photographed because of the lighting. I made my trek to the Smithsonian to view the National Collection exhibt. ![]()
