A Quote by Victor Francis Hess
It may well be said that the answer to the question: Of what do the cosmic rays in fact consist before they produce their familiar secondary radiation phenomena in the earth's atmosphere? can only be obtained from numerous measurements in the stratosphere.

A feeling that was possibly generated by experiences in my previous work on cosmic rays; more likely it was inborn and was the reason why, as a young man, I went into the field of cosmic rays.
During the last 100 years cosmic rays became scarcer because unusually vigorous action by the Sun batted away many of them. Fewer cosmic rays meant fewer clouds - and a warmer world.
It may happen that small differences in the initial conditions produce very great ones in the final phenomena. A small error in the former will produce an enormous error in the later. Prediction becomes impossible, and we have the fortuitous phenomena.
To be a scientist you have to be willing to live with uncertainty for a long time. Research scientists begin with a question and they take a decade or two to find an answer. Then the answer they get may not even answer the question they thought it would. You have to have a supple enough mind to be open to the possibility that the answer sometimes precedes the question itself.
In philosophy it is always good to put a question instead of an answer to a question. For an answer to the philosophical question may easily be unfair; disposing of it by means of another question is not.
Suicide may also be regarded as an experiment - a question which man puts to Nature, trying to force her to answer. The question is this: What change will death produce in a man's existence and in his insight into the nature of things? It is a clumsy experiment to make; for it involves the destruction of the very consciousness which puts the question and awaits the answer.
The study of celestial phenomena at radio wavelengths, radio astronomy came into being after the accidental discovery of cosmic radiation by radio engineer, Karl Jansky in 1933.
Mars does not have an atmosphere and does not have a magnetic field today, so the planet doesn't have the protection from radiation that our atmosphere and magnetic fields provide us on Earth.
Sunspots are hubs of intense magnetic activity and they trigger solar flares that launch charged particles, X-rays, ultraviolet radiation and radio waves at the Earth.
When X-rays traverse matter of any kind, this matter becomes a source of a radiation similar in character to that of the primary radiation falling upon it.
Ionizing radiation may well be the most important single cause of cancer, birth defects, and genetic disorders... The stakes for human health are very, very high in radiation matters. It is essential that people take no chance that conflict-of-interest is producing radiation databases which...cannot be trusted.
A radio telescope pointing at the sky receives radiation not only from space, but also from other sources including the ground, the earth's atmosphere, and the components of the radio telescope itself.
Natural science does not consist in ratifying what others have said, but in seeking the causes of phenomena.
There are various art forms we may or may not have talent for, may or may not have time for, and we may or may not be able to express ourselves in, but we ought to consider this fact-that whether we choose to be an environment or not, we are. We produce an environment other people have to live in. We should be conscious of the fact that this environment which we produce by our very 'being' can affect the people who live with us or work with us.
Intellectuals know how to answer the question, 'What God do I believe in?' not only through the question of 'What God do I abhor?' Intellectuals can also answer the question of 'What flag do I wave?' without having to answer the question of 'What flag do I burn.'
Couture occupies the uppermost stratosphere of fashion. It is the holy of holies, as only about 2,000 women globally are fortunate enough to wear these precious garments tailored to their exact measurements, making it perhaps the most exclusive club in the world.
