One of them was 36 times as massive as the sun, the other 29. As they approached the end, at half the speed of light, they were circling each other 250 times a second.
Scientists say they heard the faint chirp of two black holes colliding a billion light-years away, fulfilling Einstein’s general theory of relativity.

The semiconductor industry will soon abandon its pursuit of Moore's law. Now things could get a lot more interesting.

East self, West self: one's view can make all the difference in understanding each other and ourselves.
When it comes our relationship to the world, there is an East-West divide. But it can be bridged.

I would like to see this exhibit. It's fascinating and scary, the experience she has had.

For any German-reading followers who might be interested, here's a pretty critical article on the President of South Africa from a Zurich newspaper. It starts out so nice with a title of “A Toxic President.”

Sounds like that time a book publisher outed the iPad a day or two before launch, and next thing you know their partnership got cut off.

This is incredible. Everybody should read this, especially those (including me!) who have contributed to the spread of these (and other) myths. The myths include: cancer screening saves lives, antioxidants vs. free radicals, human brains are exceptionally large, preferred learning styles are best, and the human population is growing exponentially.
False beliefs and wishful thinking about the human experience are common. They are hurting people — and holding back science.

This sounds like the set-up to a joke. Never mind the facts of the matter; who can supply a good punchline?

Fascinating defense (of sorts) of returning some of the AI research and development focus back to knowledge representation:

I will make the case for the most part through a personal story. The story starts with a paper I published in 2009 in the Journal of Philosophical Logic, continues with a research project at Stanford and Duke, later with a company called Timeful, and concludes with Timeful being acquired by Google in 2015. The point of the story is there is a direct link between the original journal paper and the ultimate success of the company.

Yes, after years of rejecting and harshly dismissing the idea that he had “benefitted unduly” from government-funded upgrades to his personal residence, the president of South Africa has spontaneously decided to repay part of those funds. But, of course, he has “agreed” to do it on his terms, not those of the public protector, who called for this over 2 years ago. And, of course, he has made this announcement at a politically opportune time for himself and his party.
The president has been dogged by reports about $23 million in public funds used to make extensive upgrades to his homestead.

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.

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!

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.
