Radiation Quotes - page 3
I'll be philosophical. Until about two billion years ago, it was impossible to have any life on earth; that is, there was so much radiation on earth you couldn't have any life - fish or anything. Gradually, about two billion years ago, the amount of radiation on this planet-and probably in the entire system-reduced and made it possible for some form of life to begin... Now when we go back to using nuclear power, we are creating something which nature tried to destroy to make life possible... Every time you produce radiation, you produce something that has a certain half-life, in some cases for billions of years. I think the human race is going to wreck itself, and it is important that we get control of this horrible force and try to eliminate it... I do not believe that nuclear power is worth it if it creates radiation. Then you might ask me why do I have nuclear powered ships. That is a necessary evil. I would sink them all. Have I given you an answer to your question?
Hyman G. Rickover
And third, medical space research may lead to new safeguards against hazards common to many environments. Specifically, our astronauts will need fundamentally new devices to protect them from the ill effects of radiation which can have a profound influence upon medicine and man's relations to our present environment.
John F. Kennedy
An example of such emergent phenomena is the origin of life from non-living chemical compounds in the oldest, lifeless oceans of the earth. Here, aided by the radiation energy received from the sun, countless chemical materials were synthesized and accumulated in such a way that they constituted, as it were, a primeval "soup.” In this primeval soup, by infinite variations of lifeless growth and decay of substances during some billions of years, the way of life was ultimately reached, with its metabolism characterized by selective assimilation and dissimulation as end stations of a sluiced and canalized flow of free chemical energy.
Reinout Willem van Bemmelen
I also knew the formula that expresses the energy distribution in the normal spectrum. A theoretical interpretation therefore had to be found at any cost, no matter how high. It was clear to me that classical physics could offer no solution to this problem, and would have meant that all energy would eventually transfer from matter to radiation. ...This approach was opened to me by maintaining the two laws of thermodynamics. The two laws, it seems to me, must be upheld under all circumstances. For the rest, I was ready to sacrifice every one of my previous convictions about physical laws. ...[One] finds that the continuous loss of energy into radiation can be prevented by assuming that energy is forced at the outset to remain together in certain quanta. This was purely a formal assumption and I really did not give it much thought except that no matter what the cost, I must bring about a positive result.
Max Planck
I have satisfied myself that the [cosmic] rays are not generated by the formation of new matter in space, a process which would be like water running up a hill. Nor do they come to any appreciable amount from the stars. According to my investigations the sun emits a radiation of such penetrative power that it is virtually impossible to absorb it in lead or other substances.... This ray, which I call the primary solar ray, gives rise to a secondary radiation by impact against the cosmic dust scattered through space. It is the secondary radiation which now is commonly called the cosmic ray, and comes, of course, equally from all directions in space. [The article continues: The phenomena of radioactivity are not the result of forces within the radioactive substances but are caused by this ray emitted by the sun. If radium could be screened effectively against this ray it would cease to be radioactive, he said. ].
Nikola Tesla
The whole science of heat is founded Thermometry and Calorimetry, and when these operations are understood we may proceed to the third step, which is the investigation of those relations between the thermal and the mechanical properties of substances which form the subject of Thermodynamics. The whole of this part of the subject depends on the consideration of the Intrinsic Energy of a system of bodies, as depending on the temperature and physical state, as well as the form, motion, and relative position of these bodies. Of this energy, however, only a part is available for the purpose of producing mechanical work, and though the energy itself is indestructible, the available part is liable to diminution by the action of certain natural processes, such as conduction and radiation of heat, friction, and viscosity. These processes, by which energy is rendered unavailable as a source of work, are classed together under the name of the Dissipation of Energy.
James Clerk Maxwell
A question which has long troubled astronomers and physicists is what becomes of the energy that is continually being poured out into space by the sun and the stars. To this question a complete answer is given by the new theory. It is used up, diluted, or degraded, by the expansion of the universe. ...the light travelling through the expanding universe and, so to say, trying to reach a particular star, or stellar system, which is continually receding with great velocity, is losing energy in trying to catch up with it. It is this degradation of the light, technically known as the redshift of the spectral lines, by which we become aware of the receding velocities of the extra-galactic nebulae. It can be shown that the decrease of the total amount of radiant energy in the universe by this degradation exceeds the increase by the radiation of the stars. It would not be correct, however, to conclude that the expansion is caused by the energy thus lost by the radiation...
Willem de Sitter
I go for my completely routine mammogram and then I get a call from my gynecologist. And she says, 'Well, I have some - it's not such great news, but here it is, but it's very small and we're just going to get in there and take it right out, right away, and then you'll probably have radiation.'
Cynthia Nixon
The Maharaja of Mysore (then Governor of Mysore), ayachamarajendra Wodeyar, visited Berkeley for a day. I took him around. He was really impressed when he saw the accelerators in the Radiation Laboratory on the hill. He was happy to speak to me in Kannada and even more happy that I knew a little Sanskrit.
C. N. R. Rao
Around 1998, I went through lots of pressures and struggles. My children got married within eight months of each other, my son was diagnosed with cancer and went through major surgery and radiation, my mother had five life-threatening hospitalizations where I stayed with her, my husband's dental office burned to the ground.
Anne Graham Lotz
That's a tumor. It goes across my liver, up through my lungs, all the way around my heart. And when they were done trying to cut it out, nuke it out with radiation and chemotherapy it out, it left so much scar tissue that when I walk outside now in cold weather and take a deep breath, it feels like someone is stabbing me.
