It appears that the 126 year old cold case of Jack the Ripper has been solved by DNA testing. A shawl that was alleged to have been found next to Catherine Eddowes, one of the Ripper's victims, carries mitochondrial DNA profiles from both Eddowes' line and the familial line of one of the Ripper suspects. Polish immigrant Aaron Kosminski, who subsequently spent his later years in mental asylums, lived in the area of the killings, and was a suspect, left his DNA behind on a bloody shawl. That shawl turned out to be a time capsule for justice.
Kate Smith was a rat trained to raise a small American flag. It was trained by Kelly Buckwalter of Santa Barbara High School as "an experiment in operant conditioning" for her chemistry and psychology classes.
Over in Guam, researchers are dropping dead mice out of helicopters. The idea is that the mice, which have been doped up with acetaminophen, will land in trees and be eaten by snakes. The snakes will then die, because acetaminophen is poisonous to them. It's an experiment to see if this method will work at reducing the snake population, which is growing out of control. The video shows some of the mice falling from the skies. [NPR]
The idea that the universe is a hologram, initially presented in 1997, has been mathematically proven by Japanese researchers. And apparently the checked their work. So, perhaps Poe was right and 'all that we see or seem is but a dream within a dream' or to quote Churchill it's all 'a riddle wrapped in a mystery inside an enigma' on a hologram.
Back in 1938, Lewis F. Richardson worked out a mathematical system for predicting war. He presented his findings at a meeting of the British Association for the Advancement of Science. His conclusion: no chance of war in Europe!
The New York Times reported his findings on Aug 23, 1938:
No Sign of War Seen
Before the section on psychology, Lewis F. Richardson of Paisley arrived at the encouraging conclusion that there is no sign of war — at least no mathematical sign. For the professor reduced to beautiful differential equations general tendencies common to all nations — resentment of defiance, the suspicion that defense is concealed aggression, response to imports by exports, restraint on armaments by the difficulty of paying for them, and, last, grievances and their irrationality. The psychologists were bewildered and amused.
Mathematically, Professor Richardson treated love and hate as if they were forces that could be designated by the usual X and Y. The forces make possible two opposite kinds of drifting, one leading to suspicion, the other leading from cooperation to united organization.
The balance of power, Professor Richardson holds, is best maintained by countries of different sizes rather than by a few countries of the same size. When he concluded from his mathematical analysis that there was no chance of war at present he remarked:
"I never would have accepted this unless I proved it to myself by mathematics."
His hearers left with the feeling that Europe's feverish preparation for war is only a declaration of peace to the knife.
It's worth noting that Richardson wasn't just some random crackpot. As wikipedia notes, he's the guy who came up with the idea of weather forecasting by solution of differential equations, which is the method used today.
