Is a coin toss truly random? Not according to the "D-H-M model" which proposes that a tossed coin is slightly more likely to land on the same side that it started.
To test this model, a team of researchers at the University of Amsterdam arranged for a group of subjects to flip coins a total of 350,757 times. Their conclusion: "the data reveal overwhelming statistical evidence for the presence of same-side bias."
What this means as a money-making strategy:
If you bet a dollar on the outcome of a coin toss (i.e., paying 1 dollar to enter, and winning either 0 or 2 dollars depending on the outcome) and repeat the bet 1,000 times, knowing the starting position of the coin toss would earn you 19 dollars on average. This is more than the casino advantage for 6 deck blackjack against an optimal-strategy player, where the casino would make 5 dollars on a comparable bet, but less than the casino advantage for single-zero roulette, where the casino would make 27 dollars on average.
The song was commission by Dr. Lekelia Jenkins especially for the Human Dimensions of the Ocean Symposium at the University of Washington in 2012. This is an example of how art can be blended with science to express scientific concepts in novel ways.
The singer really pulls out all the stops starting about 45 seconds in. But I'm stumped about what scientific concepts the song is expressing. Is the singer trying to sound like a humpback whale?
Obscure world record: longest time playing the harmonica while sitting in a chair balanced on top of three wine bottles. Set by Michel Perrigaud in 1959, who played for seven-and-a-half hours.
The resonating ovoids continue to stand wherever they are. The ovoids continue to stand even if they are pushed over by waves, blown by the wind, or pushed by people. When an ovoid is pushed over, it rises back up on its own and shines brightly as it produces a tone. The light and tone continues to resonate out to other ovoids and trees nearby.
If a wave of light comes from afar, it signifies the presence of people, waves, or wind there. People gain a heightened sense of awareness of the existence of other people in the same space and the environment.
When it is quiet and the wind is not blowing and the people nearby are not interacting with the ovoids, their lights begin to flicker slowly.
Dr. Thomas' Eclectric Oil was widely sold as a cure-all in the second half of the nineteenth century and well into the twentieth. This was even though, as Wikipedia notes, it "mostly contained common ingredients such as turpentine and camphor oil."
Some of the things it supposedly cured included rheumatism, lame backs, sore throats, coughs and colds, throat and lung disease, and asthma. It could even cure "chicken flesh wounds" (see ad below).
Wikipedia notes that the name Eclectric Oil was "likely a portmanteau of the words 'eclectic' and 'electric', alluding to the then-popular belief that electricity had curative powers." Of course, the oil was not electric in any way.
