On Albert Einstein

by Robert Oppenheimer
The New York Review

 

THOUGH I KNEW EINSTEIN for two or three decades, it was only in the last decade of his life that we were close colleagues and something of friends. But I thought that it might be useful because I am sure that it is not too soon—and for our generation perhaps almost too late—to start to dispel the clouds of myth and to see the great mountain peak that these clouds hide. As always, the myth has its charms; but the truth is far more beautiful.

LATE IN HIS LIFE, in connection with his despair over weapons and wars, Einstein said that if he had to live it over again he would be a plumber. This was a balance of seriousness and jest that no one should now attempt to disturb. Believe me, he had no idea of what it was to be a plumber; least of all in the United States, where we have a joke that the typical behavior of this specialist is that he never brings his tools to the scene of the crisis. Einstein brought his tools to his crises; Einstein was a physicist, a natural philosopher, the greatest of our time.

In response to: On Albert Einstein

To the Editors:

THE BEAUTIFULLY PHRASED AND DELICATE VENOM of Dr. Oppenheimer’s “tribute” to Professor Einstein [Mar. 1] distressed me deeply. I must admit, however, that I am partial to Professor Einstein. His intervention on my behalf in 1940 resulted in my coming to this country and probably saved my life.

MY WIFE AND I VISITED HIM OFTEN IN PRINCETON. We came in contact with a human being full of empathy and warmth, a man of rare selflessness and touching modesty, always ready to oppose injustice, to fight for an underdog, or to help a victim. Dr. Oppenheimer in trying to sum up this “attitude toward human problems of Professor Einstein” suddenly found himself lacking an adequate English word for it and had—characteristically—to use a word in Sanskrit: “Ahinsa,” which he helpfully translated as “harmlessness.”

Secondary Antiprotons in Galactic Cosmic Radiation

Secondary Antiprotons in Galactic Cosmic Radiation

By Stephen Rosen

ABSTRACT

CALCULATIONS ARE PRESENTED of the production of secondary antiprotons due to inelastic collisions of high-energy primary cosmic rays with interstellar gas nuclei. Cosmic-ray diffusion theory is assumed to apply in the steady-state approximation, with a constant average beam intensity taken over space. The cosmic-ray energy spectrum, production thresholds, cosmic-ray, and target abundances and densities, and production and annihilation cross-sections are examined and utilized. The results give a very approximate energy spectrum for the antiproton flux. Astrophysical ramifications of this collision source of antiprotons are discussed in light of the dominance of leakage over annihilation as a mechanism of antiproton loss.

Ladies and Gentlemen, I give you, Albert Einstein on…

1. Talking to kids:
“If you can’t explain it to a six year old, you don’t understand it yourself.”

2. The power of imagination:
“Logic will get you from A to Z; imagination will get you everywhere.”

3. Living:
“Life is like riding a bicycle. To keep your balance, you must keep moving.”

4. The difference between creativity and intelligence:
“Creativity is intelligence having fun.”

5. Wisdom:
“A clever person solves a problem. A wise person avoids it.”

6. Memory commitment:
“Never memorize something that you can look up.”

7. Romance:
“Any man who can drive safely while kissing a pretty girl is simply not giving the kiss the attention it deserves.”

8. The past, present and future:
“Learn from yesterday, live for today, hope for tomorrow. The important thing is to not stop questioning.”

9. Success.
“Try not to become a man of success. Rather become a man of value.”

10. Love:
“[It] is a better master than duty.” And, “Gravitation is not responsible for people falling in [it].”

11. Failure
“You never fail until you stop trying.”

12. The Universe
“Black holes are where God divided by zero.”

13. Knowledge
“Any fool can know. The point is to understand.”

14. Good deeds:
“The best way to cheer yourself is to cheer somebody else up.”

15. Curiosity:
“The important thing is not to stop questioning. Curiosity has its own reason for existing.”
