Love it! More acknowledgment and understanding of our ignorance is needed.

IN the mid-1980s, a University of Arizona surgery professor, Marlys H. Witte, proposed teaching a class entitled “Introduction to Medical and Other Ignorance.” Her idea was not well received; at one foundation, an official told her he would rather resign than support a class on ignorance.

Dr. Witte was urged to alter the name of the course, but she wouldn’t budge. Far too often, she believed, teachers fail to emphasize how much about a given topic is unknown. “Textbooks spend 8 to 10 pages on pancreatic cancer,” she said some years later, “without ever telling the student that we just don’t know very much about it.” She wanted her students to recognize the limits of knowledge and to appreciate that questions often deserve as much attention as answers. Eventually, the American Medical Association funded the class, which students would fondly remember as “Ignorance 101.”
When we present knowledge as more certain than it is, we discourage curiosity.

+Julie Fugate​ Doesn't your perspective - common among many - show that this is exactly what is needed? If not now, when? Not only is the system rigged, but people think it is so rigged, it's impossible to change. I think it must change.

Wow. This is exactly what I'd expect from South Africa. But it's not SA, it's the US!
Death rates are rising even as Congress is caving to trucking industry pressure and loosening regulations.

Better drug screening of drivers needs to be done, too. The truck driver who killed 6 people in June was reported to be high on meth or some other substance.

Here's Linda Greenhouse on the Connecticut Supreme Court's decision to invalidate the state's death penalty. This made me think about the recent stories I've read about peremptory challenges.

More and more, I've come to realize that, as people are fallible and the laws they make are even more so, it's important to recognize how bias creeps (or sometimes jumps) into the system of justice and leads to systemic unfairness. This is why, as we learn more about the problems created by the system, we must change the system to remove or inhibit the natural biasing tendencies and re-establish as much fairness as possible.

1. We should abolish the death penalty because the justice system inherently leads to the innocent being found guilty and killed. (Also, the eye-for-an-eye system is cruel and inhumane.)
2. We should abolish peremptory challenges because they inherently amplify biased opinions that affect judicial decisions.

This is very significant for a certain approach to research. The article title is misleading since the issue is not really worms but replicating experiments. It's almost like economics vs. epidemiology. The economics approach is the basis of organizations like povertyactionlab.org. I wonder if we should start questioning and replicating more of the economics model.
About a quarter of the world's population could have worms - is it worth treating everyone at risk of infection?

The one candidate Lessig thinks makes sense on campaign finance is Republican firebrand Donald Trump. “He’s absolutely right,” Lessig said. “He’s rich, so he’s not dependent, [and] that would make him better than anybody else because of that lack of dependence.”

Still, Lessig cautioned: “But the idea that the only solution to this corruption is to elect billionaires is crazy. That’s what we fought a revolution about.”

That's a surprise.
Financial software company Intuit announced today in its earnings statement that it would divest its Quicken, Quickbase, and Demandforce businesses. This is big news, considering that Quicken was once at the center of Intuit.

While some economists and social scientists have sought to explain America's growing inequality by looking at the impact of capital's higher rates of return or the decline in unions and manufacturing, which Stiglitz also discusses, he also focuses on the role of politics, especially through policy decisions such as lowering the tax rates on capital gains. The top 400 earners in America, who brought in average income of $335.7 million in 2012, paid only 16.7 percent of their adjusted gross income in taxes, far below the rate paid by many middle-class Americans, for instance.
Economist Joseph Stiglitz says growing inequality has eroded chances for lower-income children to bootstrap to the top

Why does an academic publisher provide one (LaTeX) style for submissions and then later give you a proof that uses a drastically different style? Plus, they reformat your section titles, equations, figures, tables, and much more. Instead, they should have provided more advice to authors on their submission style. Finally, they ask you to submit corrections to the proof within 48 hours and tell you that, once you have submitted your corrections, it is no longer possible to change your article. There seems to be no option to redress and account for the damage that the publisher introduced.

That's hilarious. It actually might reduce some of the damage. But there were significant column width differences between mine and the proof (the latter being much larger). If I had known that, the tables and equations would have been typeset very differently.

Well-kept, finely decorated environment with a convenient location for visiting Gold Reef City and other areas of southern Johannesburg. We are a couple who stayed one night over a weekend in July to go to the Gold Reef City Casino to see a show. The facilities were mostly comfortable. Our main complaint was that our deluxe double room was cold. The large bedroom was heated by one wall panel heater, which is not sufficient in the middle of the South African winter. Naturally, the bathroom floor and shower walls, being tile, were also cold, but this is not unusual for these kinds of houses. The owners were pleasant and helpful. I enjoyed talking to Eddie about cricket and to his friendly bird who visited my shoulder. The breakfast food was simple but fine. We do think the logistics of breakfast could be done better. There was some confusion about where to find items for drinking tea and eating cereal. Other parties had problems with their orders. Perhaps it would be better to arrange not just the time of breakfast but also the order the day before the meal. Overall, the experience was not too unpleasant. We might consider returning to Villa Lugano in the summertime.

The Rhino and Lion Nature Reserve is a nice place to go for a day trip to see some animals. It's kind of like a big zoo without all of the cages except for the big predators, who have large separate fenced areas for each group (brown lions, wild dogs, white lions, and cheetahs). However, the reserve is not so big that you won't see everything in a day. Unlike the Kruger National Park, you don't have to drive around for hours wondering if you'll see lions. On the other hand, the reserve is not as wild as the park, and much of that mystique is missing. Be sure to plan your trip in advance. Look up the lion feeding time and other events. These are important for getting the most out of your trip. If you have a utility vehicle or 4x4, definitely bring it. None of the roads are paved, and in some areas, e.g. the cheetahs, you will really struggle in a 2-door hatchback like we had. Overall, we enjoyed it. The staff was helpful. The food at the Boma Restaurant was pretty good. If you're staying in the Johannesburg/Pretoria area and want to see some wild animals, you should check out the Rhino and Lion Nature Reserve.

Fabulous! My fiancée (now wife) booked the honeymoon package at Elephant Hide in Knysna. First of all, let's put aside the fact that Knysna is gorgeous and completely worth your while. There's plenty to see and do. It's one of the rare places that I actually want to visit again. Let me just say that Elephant Hide is unbelievably fantastic. The people (Ryan, Mandy, Fish, and Eliot) are all very nice, helpful, and accommodating. The room was extremely comfortable. The view of the lagoon from our bedroom, bathroom, AND shower room was outstanding. The breakfast was delicious. And the location is very convenient while also being very quiet. Oh, and I'm told that the package price was pretty good, too. I would definitely recommend Elephant Hide to anyone. I'd also stay there again, myself.

A great place to learn about snakes and other creepy crawlies. James, our tour guide, was very knowledgeable and made it a fun and enjoyable experience. He even convinced my wife (who doesn't like snakes) to hold a Burmese python!
