Physicist Quotes

Explorations into chemistry were done in our basement, sometimes with friends, and my parents must have had quite a bit of confidence in my abilities when they allowed me to experiment with explosive mixtures.
I think both running and science reflect certain character traits. I have endurance, patience, and ambition. I'm willing to work hard toward a goal, to push myself and overcome limits. Running and science both let me express these traits.
I used the Nobel money to buy a house and for the education of my children.
Imagine how many aspects of nature we would miss if we lived on the surface of the sun. Without inventing refrigerators, we would only know gaseous matter and never observe liquids or solids, and miss the beauty of snowflakes.
Laser cooling opened a new route to ultralow temperature physics. Laser cooling experiments, with room temperature vacuum chambers and easy optical access, look very different from cryogenic cells with multi-layer thermal shielding around them.
Maybe if you win a Nobel Prize in economics, you make a lot of money by giving talks... but not in my area.
My explorations of the technical world started with Legos, with which I was quite creative in constructing moving objects with the basic building blocks that were then available.
Running is a way for me to relax. With one hour of intense running, I can get a lot of physical exercise. I can relax my body. I feel a tension in my muscles when I don't run. In that sense, I need to get out a few times a week in order to do my work as a scientist, which involves a lot of sitting still.
To go below one nanokelvin is like running a mile below four minutes for the first time.
When air is hot, the molecules move fast and they have high kinetic energy. The colder the molecules are, the smaller their velocities are and, subsequently, their energy. Temperature is simply a way to characterize the energy of a system.
When I run, I think about everything: physics, family problems, plans for the weekend. I haven't made any big discoveries on a run, but it does give me time to think through problems. Some solutions are obvious, but they are only obvious when you are relaxed enough to find them.
When I was around thirty, I met my own personal challenge and finished a few marathons under three hours, and I have completed many long bicycle tours.
When I was running the marathons in Munich, I always trained by myself. Between the demands of graduate work and a young family, I had to train at unusual hours. A few times, I ran home from my lab late at night, which was 20 kilometers out of town.
Zero kelvin is the lowest possible temperature. At absolute zero, all motion comes to a standstill. It is obvious that a lower temperature is not feasible because there is no velocity smaller than zero and no energy content less than nothing.
After finishing the gymnasium in Muenchen with 9 years of Latin and 6 years of ancient Greek, history and philosophy, I decided to become a physicist. The great theoretical physicist Arnold Sommerfeld, an university colleague of my late father, advised me to begin with an apprenticeship in precision mechanics.
I grew up in Muenchen where my father has been a professor for pharmaceutic chemistry at the university. He had studied chemistry and medicine, having been a research student in Leipzig with Wilhelm Ostwald, the Nobel Laureate 1909. So I became familiar with the life of a scientist in a chemical laboratory quite early.
I was born on August 10, 1913, in Lorenzkirch, a small village in Saxony, as the fourth child of Theodor and Elisabeth Paul, nee Ruppel. All in all, we were six children. Both parents were descendants from Lutheran ministers in several generations.
In 1952, I was appointed Professor at the University of Bonn and Director of the Physics Institute, with very good students waiting for a thesis advisor.
Broadly speaking, the discovery of X-rays has increased the keenness of our vision ten thousand times, and we can now 'see' the individual atoms and molecules.
In a gas, motion has the upper hand; the atoms are moving so fast that they have no time to enter into any sort of combination with each other: occasionally, atom must meet atom and, so to speak, each hold out vain hands to the other, but the pace is too great and, in a moment, they are far away from each other again.
