A Quote by Karl Ferdinand Braun

Elementary considerations led me to the conclusion that a medium, composed of layers of different dielectric constants, must behave as a uniaxial crystal if it is assumed that the layer thicknesses are only a fraction of a wave-length.

The distinguishing of the strata, or layers, in the embryonic membrane was a turning-point in the study of the history of evolution, and placed later researches in their proper light. A division of the (disc-shaped) embryo into an animal and a plastic part first takes place. In the lower part (the plastic or vegetative layer) are a serous and a vascular layer, each of peculiar organization. In the upper part also (the animal or serous germ-layer) two layers are clearly distinguishable, a flesh-layer and a skin-layer. (1828)

Karl Ernst von Baer

The most startling result of Faraday's Law is perhaps this. If we accept the hypothesis that the elementary substances are composed of atoms, we cannot avoid concluding that electricity also, positive as well as negative, is divided into definite elementary portions, which behave like atoms of electricity.

Hermann von Helmholtz

Even if the constants which economists wish to determine were less numerous, and the method of experiment more accessible, we should still be faced with the fact that the constants themselves are different at different times. The gravitation constant is the same always. But the economic constants-these elasticities of demand and supply-depending, as they do, upon human consciousness, are liable to vary. The constitution of the atom, as it were, and not merely its position, changes under the influence of environment.

Arthur Cecil Pigou

A book consists of two layers: on top, the readable layer ... and underneath, a layer that was inaccessible. You only sense its existence in a moment of distraction from the literal reading, the way you see childhood through a child. It would take forever to tell what you see, and it would be pointless.

Marguerite Duras

Now, since the time of Newton there had been a debate about whether light was a wave - that is, a traveling disturbance in some background medium - or a particle, which travels regardless of the presence of a background medium. The observation of Maxwell that electromagnetic waves must exist and that their speed was identical to that of light ended the debate: light was an electromagnetic wave.

Lawrence M. Krauss

I guess law was always interesting to me because you deal with constants. I like to deal with constants, abstracts, constants and reason and ration, rational approaches to things. I don't know, I never really thought why I wanted to study law. But if you ask me whether I would do it again, absolutely.

Mohamed ElBaradei

The amount of sophistication varies according to the quality of the medium, and to the state of the same medium at different times; it must be attributed in the best cases physiologically to the medium, intellectually to the control.

Oliver Joseph Lodge

I think of it as the lasagna approach to writing because I'm always adding layers. I'll sometimes do it layer by layer, with dialogue, attribution, action, objects in the scene, setting... It can be sometimes that delineated.

Chelsea Cain

Government is like an onion. To understand it, you have to peel through many different layers. Most outsiders never get beyond the first or second layer.

Warren G. Bennis

Everything in Louisiana is about layers. There are layers of race, layers of class, layers of survival, layers of death, and layers of rebirth. To live with these layers is to be a true Louisianian. This state has a depth that is simultaneously beyond words and yet as natural as breathing. How can a place be both other-worldly and completely pedestrian is beyond me; however, Louisiana manages to do it. Louisiana is spooky that way.

Don Lemon

Society is a wave. The wave moves onward, but the water of which it is composed does not.

Ralph Waldo Emerson

Forgiveness isn't always a one-time thing. There are layers of it that need to be recognized in any situation -especially in a marriage. Sometimes we think we have forgiven, but we don't realize how many layers there are. And if we don't deal with each layer, hardness of heart can set in and build up to monumental proportions.

Stormie Omartian

Objective considerations of contemporary phenomena compel the conclusion that success or failure in competitive activities exhibits no tendency to be commensurate with innate capacity, but that a considerable element of the unpredictable must invaria.

George Orwell

There are different groups of people in your life that you behave slightly differently with. You behave one way with your family. You behave in a different way with your work colleagues. You behave differently with your friends from the movie club, your fitness instructor - all subtly different personas.

Charlie Brooker

When I say there's a little bit of Erika Jayne in everybody, what I mean by that is: No one is one way all the time. No one is buttoned up all the time and no one is wild all the time. There are different parts to your personality, different layers - and that's really what Erika Jayne is, another layer to a human being.
