lottery
gregladen | November 17, 2013I would like to propose a lottery.
Cost of ticket: $10.00
Prize: The winner's choice of an American-made electric car or hybrid car off of an approved list.
The cars would be provided at discount from them manufacturer. The manufacturer benefits from the publicity (free-ish advertising) and from having more of their cars on the road in communities where they might otherwise be very rare.
This would act like a Rotating Savings and Credit Association (ROSCA). A ROSCA is a way that a group of people can obtain a costly item with little available cash and low or zero interest loan. Every…
lborkowski | May 7, 2012A recent Freakonomics podcast tells one of my favorite public health stories: how observant physician Ignaz Semmelweis figured out how to slash the incidence of childbed, or puerperal, fever, a disease that killed 10-15% of the women who gave birth in the doctor-staffed ward of the Vienna General Hospital in the mid-nineteenth century. (Death rates were similarly alarming elsewhere, since germ theory hadn't yet taken hold.)
As the podcast explains, Semmelweis observed that the death rate from childbed fever was lower among women who delivered babies in the ward staffed by midwives compared to…
drorzel | August 2, 2010Thoreau at Unqualified Offerings gets credit for inspiring two posts today with his proposed Murphy's Law experiment and this one, about an unrelated issue in quantum measurement. This is an analogy suggested by a colleague a couple of years ago, comparing the projection of a quantum wavefunction in the measurement process to the lottery.
The classic example of this problem is something like the double slit experiment with single particles. You have some position-sensitive detector that we can imagine as being made up of a large number of pixels, each having some probability of detecting a…
neurophilosophy | May 14, 2010GAMBLING is extremely popular, with lottery tickets, casinos, slot machines, bingo halls and other forms of the activity generating revenues of more than £80 billion each year in the UK alone. For most people, gambling is nothing more than an entertaining way to pass the time. But for some, it becomes a compulsive and pathological habit - they spend increasing amounts of time gambling, because tolerance builds up quickly, and experience withdrawal symptoms when they aren't gambling.
The terms "tolerance" and "withdrawal" are normally associated with drug addiction, and indeed pathological…
