Trump and Putin vs. America
Though Boeing hasn’t decided the final dimensions, the airplane (which doesn’t have a name yet) would be larger than a business jet but smaller than a 737, Bowcutt says, so presumably seating between, say, 20 and 100 passengers. It would cruise at 95,000 feet, which is 30,000 feet higher than the supersonic Concorde flew, and a full 60,000 feet higher than the average airliner. That altitude maximizes the efficiency of the engines and keeps turbulence to a minimum, since the air density is so much lower that far up in the air.
The G-force feeling upon takeoff would last a full 12 minutes as the plane accelerated to cruising speed (on a conventional craft the feeling lasts just a few seconds) but the cruising-altitude experience should be serene, with stunning views featuring the earth’s curvature at the horizon and the blackness of space above. “Other than that you would also weigh a bit less,” Bowcutt says. “At that altitude you’ll be a few pounds lighter than on the ground.”
As such, a stable tilt just might be a necessary ingredient for life. It’s an interesting finding given that the Earth’s tilt never changes drastically thanks to the Moon.
For some meme creators, Twitter and Tumblr are a canvas, while Instagram is the wall where they display their work.
A recent paper* by Hendrik Bessembinder of Arizona State University explains why. Since 1926, most stockmarket returns in America have come from a tiny fraction of shares. Just five stocks (Apple, ExxonMobil, Microsoft, GE and IBM) accounted for a tenth of all the wealth created for shareholders between 1926 and 2016. The top 50 stocks account for two-fifths of the total. More than half the 25,000 or so stocks listed in America in the past 90 years proved to be worse investments than Treasury bills.
Putting these results together, Ms Ilardo and Dr Nielsen argue that the need to collect food by diving has indeed led to the evolution, in the case of the Bajau, of a group who are literally born to dive. Whether that evolution was driven by the failure of those who could not dive well to collect enough food to sustain a large family, or rather, of their dying in the attempt to do so, remains to be determined.
