Last week, we (the Atlantic) asked readers to draw their best guess of how the U.S. murder rate changed between 1985 and 2014. More than 11,000 of you participated. Here’s the result, with bright red indicating the areas with the most guesses. The line represents the real homicide rating.
This event was recorded on 1996/06/21 14:08:00 (run 1944 subrun 78 event 474301).
The left image is meant for the right eye and the right image for the left eye. Distance between eyes was set to 1 m. To view this event one should cross the eyes. Don’t put the image too close. Put your finger tip between the picture and your eyes, close to your eyes. Look at the tip. Put it at such distance that the background SK image blends into 3 images, the middle one is the stereo image. It is blurred as long as you focus on your finger. Now the most difficult part. Try to focus on the SK image without uncrossing your eyes. It may take a few minutes to learn to do it.http://www.ps.uci.edu/
This event occurred at 1998-04-04 08:35:22. It was reconstructed as a muon with momentum of 603 MeV. The time scale width is 162 ns. This event was followed by another event (not shown) 4 us later which was caused by an electron produced by the decay of the stopped muon. This gives us an additional confirmation that this is a muon. http://www.ps.uci.edu/
An image of the shadow of the Moon in muons as produced by the 700m subterranean Soudan 2 detector in the Soudan Mine in Minnesota. The shadow is the result of approximately 120 muons missing from a total of 33 million detected in Soudan 2 over its 10 years of operation. The cross denotes the actual location of the Moon. The shadow of the Moon is slightly offset from this location because cosmic rays are electrically charged particles and were slightly deflected by the Earth’s magnetic field on their journey to the upper atmosphere. The shadow is produced due to the shielding effect the Moon has on galactic and cosmic rays, which stream in from all directions. The cosmic rays normally strike atoms high in the upper atmosphere, producing showers of muons and other short-lived particles. Wikipedia
