Exact Exponential Algorithms
Many computational problems have been shown to be intractable, either in the strong sense that no algorithm exists at all—the canonical example being the undecidability of the Halting Problem—or that no efficient algorithm exists. From a theoretical perspective perhaps the most intriguing case occur...

|At U Maryland I took a course from Bill Gasarch on computation. The first thing he said to the class, famously, was "I'm going to show you that there are problems that are impossible to solve. Then I'm going to show you some problems even harder than those.""
This is a good read.

"In fact, hostility to mathematics is endemic in
our culture. Imagine a conversation:
A: What do you do?
B: I am a ———.
A: Oh, I hate that.
Ideally this response would be limited to such occupations as “serial killer”, “child pornographer”,
and maybe “politician”, but “mathematician” seems
to work. It is common enough that many of us are
reluctant to identify ourselves as mathematicians.
Paul Halmos is said to have told outsiders that he
was in “roofing and siding”!"

Elizabeth Kolbert: The Science of Sleeplessness
New technologies have made the study of sleep cheaper, easier, and less intrusive. But if this is sleep research’s golden age, then why are we all so tired?
Hasnain says:
Teen-agers are owls, which is why high schools are filled with students who look (and act) like zombies. Roenneberg advocates scheduling high-school classes to begin later in the day, and he cites studies showing that schools that delay the start of first period see performance, motivation, and attendance all increase. (A school district in Minnesota that switched to a later schedule found that the average S.A.T. scores for the top ten per cent of the class rose by more than two hundred points, a result that the head of the College Board called “truly flabbergasting.”) But, Roenneberg notes, teachers and school administrators generally resist the change, preferring to believe that the problem is insoluble.
