Some quotes[edit]

"For a successful technology, reality must take precedence over public relations, for nature cannot be fooled," ~Richard Feynman, criticizing NASA’s management for their serious deficiencies, in his appendix to the Rogers Commission Report

"Hear the truth from whomever says it," ~Maimonides, introduction to his commentary on Ethics of the Fathers

"Remember...the most important thing you should learn in residency is to learn how to think!" ~Dr. Louis Albert DiPede, Assistant Professor of Prosthodontics, Rutgers School of Dental Medicine

"And, frankly, the mean is meaningless!" ~Dr. Gary Greenstein, Associate Professor of Periodontics, Columbia University College of Dental Medicine

"Half a bee, philosophically, must ipso facto half not be. But half the bee has got to be vis a vis his entity - d'you see? But can a bee be said to be or not to be an entire bee when half the bee is not a bee due to some ancient injury?" ~Eric Idle, Monty Python

"Put your hand on a hot stovetop for a minute and it seems like an hour. Sit next to a pretty girl for an hour and it seems like a minute. Now that's relativity." ~Albert Einstein

"Human existence is based upon two pillars: Compassion and knowledge. Compassion without knowledge is ineffective; knowledge without compassion is inhuman," ~Victor Frederick Weisskopf

"Whenever you find yourself on the side of the majority, it is time to pause and reflect." ~Mark Twain

"All we know is that we don’t know," ~Noel Gallagher, Oasis, The Masterplan

"Life is what happens to you when you're busy making other plans," ~John Lennon

"I have never let my schooling interfere with my education," ~Mark Twain

"Don't confuse ignorance with a point of view," ~Dilbert

"It is fun to have fun, but you have to know how" ~Dr. Seuss, The Cat in the Hat

The storm starts
when the drops start dropping.
When the drops stop dropping,
then the storm starts stopping. ~Dr. Seuss, Oh Say Can You Say?
If you're a bird, be an early early bird,
to catch that worm for you dinner plate.
If you're a bird, be an early early bird,
but if you're a worm, sleep late. ~Shel Silverstein, Where the Sidewalk Ends

"Thank God I'm an atheist!" ~Ron Kuby, formerly of the The Curtis and Kuby Show, WABC

"One often meets his destiny on the road he takes to avoid it" ~Grand Master Oogway, Kung Fu Panda

"If you only do what you can do, you'll never be more than you are now" ~Master Shifu, Kung Fu Panda 3

"It used to be, everyone was entitled to their own opinion, but not their own facts. But that's not the case anymore. Facts matter not at all. Perception is everything." ~Stephen Colbert, explaining truthiness.

"Smart people believe weird things because they are skilled at defending beliefs they arrived at for non-smart reasons." ~Michael Shermer, quoted in Thomas Kida's Don't Believe Everything You Think

I wonder why. I wonder why.
I wonder why I wonder.
I wonder why I wonder
why I wonder why I wonder. ~Richard Feynman
"Can anyone even remember now what Nixon did that was so terrible? He ended the war in Vietnam, brought home the POWs, ended the war in the Mideast, opened relations with China, started the first nuclear weapons reduction treaty, saved Eretz Israel's life, started the Environmental Protection Administration. Does anyone remember what he did that was bad?
Oh, now I remember. He lied. He was a politician who lied. How remarkable. He lied to protect his subordinates who were covering up a ridiculous burglary that no one to this date has any clue about its purpose. He lied so he could stay in office and keep his agenda of peace going. That was his crime. He was a peacemaker and he wanted to make a world where there was a generation of peace. And he succeeded.
That is his legacy. He was a peacemaker. He was a lying, conniving, covering up peacemaker. He was not a lying, conniving drug addict like JFK, a lying, conniving war starter like LBJ, a lying, conniving seducer like Clinton — a lying, conniving peacemaker." ~Ben Stein

"Our eyes locked, and someone threw away the key." ~Annie Dillard, Living like Weasels

Tell me, why do people always say that it was natural for man to assume that the Sun went around the Earth rather than that the Earth was rotating?
Well, obviously because it just looks as though the Sun is going around the Earth.
Well, what would it have looked like if it had looked as though the Earth were rotating? ~Ludwig Wittgenstein

Favorite songs[edit]

Favorite books[edit]

Why I am enamoured of British literature, exemplified[edit]

"Mr. Bennet, how can you abuse your own children in such a way? You take delight in vexing me. You have no compassion on my poor nerves."
"You mistake me, my dear. I have a high respect for your nerves. They are my old friends. I have heard you mention them with consideration these twenty years at least."
~Mr. Bennet responding to his wife in Pride and Prejudice, chapter 1 (Jane Austen)
"I said he might, and he shook hands with me again, and emptied his glass and turned it upside-down. I did the same; and if I had turned myself upside-down before drinking, the wine could not have gone more directly to my head."
~Pip referring to Mr. Pumblechook in Great Expectations, chapter 19 (Charles Dickens)
"I, trembling in spirit and worshipping the very hem of her dress; she, quite composed and most decidedly not worshipping the hem of mine."
~Pip referring to Estella, chapter 29
"They both had weak eyes, which I had long attributed to their chronically looking in at keyholes, and they were always at hand when not wanted; indeed that was their only reliable quality besides larceny."
~Pip referring to his housekeeper and her niece, chapter 40

Favorite examples of ridiculously poor sentence structure in peer reviewed, published articles[edit]

An overhanging dental restoration is primarily found in the Class II restoration, since access for interdental cleansing is often difficult in these areas, even for patients with good oral hygiene.
Matthews, DC; Tabesh, M: "Detection of localized tooth-related factors that predispose to periodontal infections" Periodontology 2000 24;2004:136-150.
