To compensate for the fast-shrinking labour force, Japan would need______.
Why does the author attach so much importance to humanistic studies？
M: Some people who write to me say this.They say that if you didn't have a monopoly, you wouldn't be able to do the things you do. Well, I don't think we do anything deliberately to upset our customers. We have particular problems. Since 1946, when the Transport Act came in, we were nationalized.
W: Do you think that's a good thing？ Has it been a good thing for the railways, do you think, to be nationalized？
M: Oh I think so, yes, because in general,modes of transport are all around. Let's face the fact. The car arrived. The car is here to stay. There is no question about that
W: So what are you saying then？ Is that if the railways haven't been nationalized, they would simply have disappeared？
M: Oh, I think they would have. They're disappearing fast in America.Er, the French Railways lose 1 billion pounds a year; the German Railways, 2 billion pounds a year. But you see, those governments are prepared to pour money into the transport system to keep it going.
W: So in a sense, you are caught between two extremes. On the one hand, you're trying not to lose too much money. And on the other hand, you've got to provide the best service. M: Yes, you are right.

Many physicists say the next Einstein hasn't been born yet, or is a baby now. That's because the quest for a unified theory that would account for all the forces of nature has pushed current mathematics to its limits. New math must be created before the problem can be solved. But researchers say there are many other factors working against another Einstein emerging anytime soon.
For one thing, physics is a much different field today. In Einstein's day, there were only a few thousand physicists worldwide, and the theoreticians who could intellectually rival Einstein probably would fit into a streetcar with seats to spare.
Education is different, too. One crucial aspect of Einstein's training that is overlooked is the years of philosophy he read as a teenager—Kant, Schopenhauer and Spinoza, among others. It taught him how to think independently and abstractly about space and time, and it wasn't long before he became a philosopher himself.
"The independence created by philosophical insight is—in my opinion—the mark of distinction between a mere artisan(工匠) or specialist and a real seeker after truth, " Einstein wrote in 1944.
And he was an accomplished musician. The interplay between music and math is well-known. Einstein would furiously play his violin as a way to think through a knotty physics problem.
Today, universities have produced millions of physicists. There aren't many jobs in science for them, so they go to Wall Street and Silicon Valley to apply their analytical skills to more practical—and rewarding—efforts.
"Maybe there is an Einstein out there today, " said Columbia University physicist Brian Greene, "but it would be a lot harder for him to be heard. "
Especially considering what Einstein was proposing.
"The actual fabric of space and time curving？ My God, what an idea!" Greene said at a recent gathering at the Aspen Institute. "It takes a certain type of person who will bang his head against the wall because you believe you'll find the solution. "
Perhaps the best examples are the five scientific papers Einstein wrote in his "miracle year" of 1905. These "thought experiments" were pages of calculations signed and submitted to the prestigious journal Annalen der Physik by a virtual unknown. There were no footnotes or citations.
What might happen to such a submission today？
"We all get papers like those in the mail, " Greene said. "We put them in the junk file. "
What do scientists seem to agree upon judging from the first two paragraphs？
