A Quote by Gilbert N. Lewis
I therefore take the liberty of proposing for this hypothetical new atom, which is not light but plays an essential part in every process of radiation, the name photon.

If we have an atom that is in an excited state and so is going to emit a photon, we cannot say when it will emit the photon. It has a certain amplitude to emit the photon at any time, and we can predict only a probability for emission; we cannot predict the future exactly.
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.
I'll be looking for you, Will, every moment, every single moment. And when we do find each other again, we'll cling together so tight that nothing and no one'll ever tear us apart. Every atom of me and every atom of you... We'll live in birds and flowers and dragonflies and pine trees and in clouds and in those little specks of light you see floating in sunbeams... And when they use our atoms to make new lives, they wont' just be able to take one, they'll have to take two, one of you and one of me, we'll be joined so tight.
When a photon comes down, it interacts with electrons throughout the glass, not just on the surface. The photon and electrons do some kind of dance, the net result of which is the same as if the photon hit only on the surface.
I'm proposing to you that photography is a language on its own, which is that when you look at images you do derive ideas; and I'm also proposing to you that you can derive ideas without going through words. So I'm forcing you to really look. And this process of looking, it's like a new set of ideas that are being proposed to you.
The incomplete knowledge of a system must be an essential part of every formulation in quantum theory. Quantum theoretical laws must be of a statistical kind. To give an example: we know that the radium atom emits alpha-radiation. Quantum theory can give us an indication of the probability that the alpha-particle will leave the nucleus in unit time, but it cannot predict at what precise point in time the emission will occur, for this is uncertain in principle.
To history therefore I must refer for answer, in which it would be an unhappy passage indeed, which should shew by what fatal indulgence of subordinate views and passions, a contest for an atom had defeated well founded prospects of giving liberty to half the globe.
When Democrats are proposing things like a Green New Deal and Medicare for all and proposing that they take away your private insurance... it's very obvious to people that they've gone in a radical direction that will not work.
Attention may sound dull, but it is an essential aspect of consciousness. In fact, it governs what it is that we turn out to be conscious of, and therefore plays a part in the coming into being of whatever exists for us.
The essential factor in the transition of the baroque to photography is not the perfecting of a physical process... rather does it lie in a psychological fact, to wit, in completely satisfying our appetite for illusion by a mechanical reproduction in the making of which man plays not part. The solution is not to be found in the result achieved, but in the way of achieving it.
One of the deadliest issues is the nuclear radiation pouring from every nuclear power station in the world. With every atomic process and experimentation that is going on, high-level nuclear radiation is pouring out at the highest level.
As liberty of thought is absolute, so is liberty of speech, which is 'inseparable' from the liberty of thought. Liberty of speech, moreover, is essential not only for its own sake but for the sake of truth, which requires absolute liberty for the utterance of unpopular and even demonstrably false opinions.
Since we can produce all types of light by means of hot bodies, we can ascribe, to the radiation in thermal equilibrium with hot bodies, the temperature of these bodies, and thus every radiation, even that issuing from a phosphorescent body, has a certain temperature for every colour.
There are allowable limits for radiation going - I mean there's radiation all around us. There's radiation from your television set. There's radiation from your computer. There's radiation actually occurring in the ground.
Is it permitted for Catholics to be present at, or to take part in, conventions, gatherings, meetings, or societies of non-Catholics which aim to associate together under a single agreement everyone who, in any way, lays claim to the name of Christian? In the negative! ... It is clear, therefore, why this Apostolic See has never allowed its subjects to take part in the assemblies of non-Catholics. There is one way in which the unity of Christians may be fostered, and that is by furthering the return to the one true Church of Christ for those who are separated from Her.
A different conception of society, very different from that which now prevails, is in process of formation. Under the name of Anarchy, a new interpretation of the past and present life of society arises, giving at the same time a forecast as regards its future, both conceived in the same spirit as the above-mentioned interpretation in natural sciences. Anarchy, therefore, appears as a constituent part of the new philosophy, and that is why Anarchists come in contact, on so many points, with the greatest thinkers and poets of the present day.
