 Skepticism in Science has Grown

In 1982, polls showed that 44 percent of Americans believed God had created human beings in their present form. Thirty years later, the fraction of the population who are creationists is 46 percent. In 1989, when “climate change” had just entered the public lexicon, 63 percent of Americans understood it was a problem. Almost 25 years later, that proportion is actually a bit lower, at 58 percent. The timeline of these polls defines my career in science. In 1982 I was an undergraduate phy...

 Production Costs for Antimatter

Fermilab produces antiprotons in medium-energy collisions of protons with a lithium target. Every now and then these collisions will produce an antiproton, which is then directed into the storage ring beneath the buffalo. When operating at average efficiency, Fermilab can produce about 50 billion antiprotons an hour in this way. Assuming that the Antiproton Source is operating about 75 percent of the time throughout the year, this is about 6000 hours of operation per year, so Fermilab produce...

 The U-Shape of Automation

As we look ahead, we see these three trends not only accelerating but also evolving. For instance, new research by David Autor and David Dorn has put an interesting twist on the SBTC story. They find that the relationship between skills and wages has recently become U-shaped. In the most recent decade, demand has fallen most for those in the middle of the skill distribution. The highest-skilled workers have done well, but interestingly those with the lowest skills have suffered less than thos...
