Zitat des Tages über Physiker / Physicists:
Most medical physicists work in the physics of radiation oncology making sure that the desired dose is given to the cancer and the dose to normal tissues are minimized.
When general relativity was first put forward in 1915, the math was very unfamiliar to most physicists. Now we teach general relativity to advanced high school students.
Most of physics is about energy, and physicists understand inefficiencies. I wanted to write a book about our energy options in a neutral, human-accessible form.
Someone like Einstein was quite clearly a moralist, and he had a very highly developed political vision and was very spiritual in his way, and there are many biologists and physicists of the first order who are like that.
The weapons were conceived and created by a small band of physicists and chemists; they remain a cataclysmic threat to the whole of human society and the natural environment.
The greatest progress is in the sciences that study the simplest systems. So take, say, physics - greatest progress there. But one of the reasons is that the physicists have an advantage that no other branch of sciences has. If something gets too complicated, they hand it to someone else.
Physicists are more like avant-garde composers, willing to bend traditional rules... Mathematicians are more like classical composers.
When I took office, only high energy physicists had ever heard of what is called the Worldwide Web... Now even my cat has its own page.
There are now over 5,000 medical physicists in the U.S more than 50 times the number in 1958.
We should note that this latter type of shift was successfully amplified to a considerable extent by Russian physicists using the intense light of a ruby laser whose wavelength is close to that of a transition of the potassium atom.
The verbal interpretation, on the other hand, i.e. the metaphysics of quantum physics, is on far less solid ground. In fact, in more than forty years physicists have not been able to provide a clear metaphysical model.
As we know from the work of certain fundamental physicists, people like Einstein were very dependent upon conjuring up visual images in order to imagine things which otherwise were not easily formulated.
The financial sector has so distorted salaries that physicists are getting drawn into the financial sector. All that has led to an undersupply of people committed to the public sector.
We physicists know that a beautiful postulate is more likely to be correct than an ugly one. Why not adopt this Postulate of Eternal Life, at least as a working hypothesis?
Modern scientific knowledge appeared piecemeal. Historians wrote about human history; physicists tackled the material world; and biologists studied the world of living organisms. But there were few links between these disciplines, as researchers focused on getting the details right.
Physicists and astronomers see their own implications in the world being round, but to me it means that only one-third of the world is asleep at any given time and the other two-thirds is up to something.
Physics is, hopefully, simple. Physicists are not.
With the exception of gravitation and radioactivity, all of the phenomena known to physicists and chemists in 1911 have their ultimate explanation in the laws of quantum electrodynamics.
I have a tendency, more than most other physicists, to try to figure out everything all at once, before I publish. And even to try to figure out everything in my head, without pencil and paper.
The development of quantum mechanics early in the twentieth century obliged physicists to change radically the concepts they used to describe the world.
The way in which mathematicians and physicists and historians talk is quite different, and what a physicist means by physical intuition and what a mathematician means by beauty or elegance are things worth thinking about.
Particle physicists may freeze a second, open it up, and explore its dappled contents like surgeons pawing through an abdomen, but in real life, when events occur within thousandths of a second, our minds cannot distinguish past from future.
Energy is a concept that has been coined by physicists. There is no observable thing known as energy anywhere.
Everything starts somewhere, although many physicists disagree.
I found collaborating with congenial doctors about problems that physicists could help solve was very satisfying. I also like educating anybody who would listen!
As physics students, we are taught that physicists are smart, that chemists are moderately acceptable, and that biologists are certainly not very intelligent. So I wasn't inclined to take a biology course. But my father insisted, and maybe what he had in mind was that, if there were no jobs in physics, I would end up being a doctor.
Chemistry has been termed by the physicist as the messy part of physics, but that is no reason why the physicists should be permitted to make a mess of chemistry when they invade it.
As a physicist, I can state that none of the 18 physicists who signed the Statement works in this field; nor to my knowledge has ever published a paper on this subject.
In some sort of crude sense, which no vulgarity, no humor, no overstatement can quite extinguish, the physicists have known sin; and this is a knowledge which they cannot lose.
Our enemy is Al Qaeda and its allies, people who have publicly said they wish to attack the United States again, people who have publicly called on nuclear physicists and engineers to help them gain access to nuclear weapons, which, as the whole world knows, Pakistan has.
It would be a poor thing to be an atom in a universe without physicists, and physicists are made of atoms. A physicist is an atom's way of knowing about atoms.
Our science has become terrible, our research dangerous, our findings deadly. We physicists have to make peace with reality. Reality is not as strong as we are. We will ruin reality.
Physics is becoming too difficult for the physicists.
You have that one basic string, but it can vibrate in many ways. But we're trying to get a lot of particles because experimental physicists have discovered a lot of particles.
The ability to work together has to be in the blood of particle physicists. They learn very early on that it is impossible to advance on one's own and that constant exchange is necessary.
It seems hopelessly improbable that any particular rules accidentally led to the miracle of intelligent life. Nevertheless, this is exactly what most physicists have believed: intelligent life is a purely serendipitous consequence of physical principles that have nothing to do with our own existence.
