For as long as one has no further point of reference, apart from the position of the maximum, the wavelength thus remains uncertain by an integral factor.

There is no doubt that I, also, had long been aware of the problem, i.e. producing X-ray interferences, before the inherent difficulties had finally been surmounted.

If diffraction or interference phenomena were to be sought it was therefore necessary, in accordance with the basic principles of wave theory, to select for the test arrangement far smaller decisive dimensions than those employed in corresponding tests with visible light.

Notwithstanding these major arguments the wave theory initially did not meet with complete acceptance.

For both reasons, owing to the thermal motion and to the working together of various wavelengths, factors arise which, in a similar manner to the structural factor, exert some influence upon the brightness of the interference points but not upon their location.

For in 1900 all electromagnetic radiation of longer wavelengths was already known at least to the extent that one could not seek in it the more striking characteristics of X-rays such as, for example, the strong penetrating power.

For as long as one has no further point of reference, apart from the position of the maximum, the wavelength thus remains uncertain by an integral factor.

I got to say 'Hi' to Dolly Parton, which my mom thought was kind of cool.

A revised schedule is to business what a new season is to an athlete or a new canvas to an artist.

Our family were outsiders, and I've always had a sense of the outsider, the underdog, and a strong sense of justice towards people who are excluded.

As a young concert-going person, I was never enamoured with celebrities who would walk out to feature in certain songs and then walk off.

I am a literary animal. For me, everything ends in literature.

You can't suddenly say, 'I want a brand new habit tomorrow,' and expect it to be easy and effortless.

I think my parents raised me well. And I'm pretty straight edge. All my friends make fun of me for being straight edge.

We're more sexually repressed than men, having been given a much more strict puritanical code of behavior than men ever have.

With 'Selma,' I grew up in Alabama, 45 minutes away from Selma. I have gone to that commemorative march many times with my parents.

I feel I will always have that spirit bear with me, so I will always feel protected.

I just want to do my best to prove myself.

I call my golden retriever Cara my 'white wolf.' She's changed my attitude and made me write this book where the wolf is the hero, not the villain.

At the ballet you really feel like youre in the presence of something outside the rest of your life. Higher than the rest of your life.

Whatever anyone says, I think the opposite will happen.

Please don't quote me.

When you realize you're alive, you can live life!

I think people underestimate the romance audience. It's everything from career women to high school girls to elderly women. I have male readers, too, especially for the Civil War books.

Success in training the boy depends largely on the Scoutmaster's own personal example.

I got to where I couldn't listen to country radio. Country music is supposed to have steel and fiddle. When I hear country music, it should be country.

I didn't think I'd ever be an actor.

And the lost heart stiffens and rejoices in the lost lilac and the lost sea voices and the weak spirit quickens to rebel for the bent golden-rod and the lost sea smell quickens to recover.

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.

I'm like Johnny Cash. I only wear black.

I'm a mother of a three-year-old, but when I started 'California,' my son wasn't even a twinkle in my eye. Because the book took as long as it did, I wrote it before I was pregnant, while I was pregnant, and as a new mother - so I enjoyed a diversity of experiences while creating this world.
