PhD Quotes (10 quotes)

At first I became depressed. I seemed to be getting worse pretty rapidly. There didn’t seem any point in working on my Ph.D. because I didn’t know I would live long enough to finish it.
In a message to his 70th birthday celebration, delivered at a public symposium in Cambridge, England (which ill health prevented him from attending). As quoted in Alok Jha, 'Stephen Hawking marks 70th birthday with speech to leading cosmologists', The Guardian (8 Jan 2012). (Around the age of 21, as he started his Ph.D. in Cambridge, Hawking was diagnosed with motor neurone disease.)

High school counselors would try to railroad Hispanic students into the AD nursing programs. I’m proud of the fact that we’ve [National Association of Hispanic Nurses] been able to push more of our nurses on to earn doctoral degrees. We now have a number of Hispanic doctoral nurses who are very good at research and have been recognized worldwide for their studies. For example, Mary Lou de Leon Siantz has done work with Mexican migrant families that was truly ground-breaking.
As quoted in 'Minority Mental Health: Shining a Light on Unique Needs and Situations', Minority Nurse (30 Mar 2013) online at minoritynurse.com

I like to tell students that the jobs I took [at NASA] after my Ph.D. were not in existence only a few years before. New opportunities can open up for you in this ever changing field.
From interview, 'Happy 90th Birthday, Nancy', on NASA website (30 May 2017).

I refrained from writing another one, thinking to myself: Never mind, I will prove that I am able to become a greater scientist than some of you, even without the title of doctor.
Reaction when his thesis (1922) on rocket experiments was rejected as too cursory. In Astronautics (1959), 4, No. 6, 103.

I’ve never made a discovery myself, unless by accident. If you write glibly, you fool people. When I first met Asimov, I asked him if he was a professor at Boston University. He said no and … asked me where I got my Ph.D. I said I didn’t have one and he looked startled. “You mean you’re in the same racket I am,” he said, “you just read books by the professors and rewrite them?” That’s really what I do.
Quoted in Sally Helgeson, 'Every Day', Bookletter (6 Dec 1976), 3, No. 8, 3. As quoted and cited in Dana Richards, 'Martin Gardner: A “Documentary”', collected in Elwyn R. Berlekamp and Tom Rodgers (ed.) The Mathemagician and Pied Puzzler: A Collection in Tribute to Martin Gardner (1999), 8-9.

Like all things of the mind, science is a brittle thing: it becomes absurd when you look at it too closely. It is designed for few at a time, not as a mass profession. But now we have megascience: an immense apparatus discharging in a minute more bursts of knowledge than humanity is able to assimilate in a lifetime. Each of us has two eyes, two ears, and, I hope, one brain. We cannot even listen to two symphonies at the same time. How do we get out of the horrible cacophony that assails our minds day and night? We have to learn, as others did, that if science is a machine to make more science, a machine to grind out so-called facts of nature, not all facts are equally worth knowing. Students, in other words, will have to learn to forget most of what they have learned. This process of forgetting must begin after each exam, but never before. The Ph.D. is essentially a license to start unlearning.
Voices In the Labyrinth: Nature, Man, and Science (1979), 2.

One could say you can't do any experiment which exceeds the lifetime of a Ph.D. student.

The idea of winning a doctor’s degree gradually assumed the aspect of a great moral struggle, and the moral fight possessed immense attraction for me.
In Pioneer Work in Opening the Medical Profession to Women (1895), 29.

The modern version of Buridan’s ass [a figurative description of a man of indecision] has a Ph.D., but no time to grow up as he is undecided between making a Leonardo da Vinci in the test tube or planting a Coca Cola sign on Mars.
Voices in the Labyrinth: Nature, Man, and Science (1979), 3.

What I really want is a creative person. You can always hire a Ph.D. to take care of the details.
A recollection by Ray Hunder on Drew's philosophy, as quoted in A Century of Innovation: The 3M Story (2002), 27. (Note: The quote is in the words of Ray Hunder, and not necessarily a verbatim quote as spoken by Drew.)

Carl Sagan Thumbnail In science it often happens that scientists say, 'You know that's a really good argument; my position is mistaken,' and then they would actually change their minds and you never hear that old view from them again. They really do it. It doesn't happen as often as it should, because scientists are human and change is sometimes painful. But it happens every day. I cannot recall the last time something like that happened in politics or religion. (1987) -- Carl Sagan
