“Clearly, some time ago makers and consumers of American junk food passed jointly through some kind of sensibility barrier in the endless quest for new taste sensations. Now they are a little like those desperate junkies who have tried every known drug and are finally reduced to mainlining toilet bowl cleanser in an effort to get still higher.”
—Bill Bryson (b. 1951)

“Nothing can be more incorrect than the assumption one sometimes meets with, that physics has one method, chemistry another, and biology a third.”
