A Quote by Martin Chalfie

We know what molecules are needed to sense light - what turns that signal that detects light into an electrical signal. We know how smells are detected. But we have a vast number of senses for which we know what the signal is, but we don't know what the receiver is.

The neuro-biology of playing a musical instrument is completely scientific, but it’s also an absolute miracle, that you’re taking basically a calcium bucket filled with salt-water that’s run by a weak electrical signal, and you’re using it to move your flesh around in order to manipulate an instrument which disturbs air molecules between you and the listener, and then the listener’s ears picks up those disturbed air molecules which generates a weak electrical signal to their calcium bucket full of salt water, and they feel a feeling. That’s miraculous, and that’s where I live.

If you have to signal a bartender to get a drink, then they're not looking at you, which is their problem. They're not doing their job. So don't feel rude when you signal a bartender. They're the ones who caused you to signal them. Go for it.

I think we have deluded ourselves into believing that people don't know that abortion is killing. So any pretense that abortion is not killing is a signal of our ambivalence, a signal that we cannot say yes, it kills a fetus.

According to the belief, molecules closer together than 200 nanometers could not be told apart with focused light. This is because, in a packed molecular crowd, the molecules shout out their fluorescence simultaneously, causing their signal, their voices, to be confused.

Just a little bit of exposure to this pulsed digital signal, which is now a cellphone signal, could weaken membranes of the brain.

If I need you I'll give you a signal.' What signal?" I'll imitate the scream of a terrified little girl

I think Putin will have to find a way to signal, even if it's a modest signal, an openness to dialogue.

Charles Dallara

It's seriously unfortunate when an elected official of the federal government says she's [Michelle Bachmann] going to deliberately break the law. I don't know what kind of signal she thinks that sends, but if she believes that's a good signal, I'm sad for the country. I think that it's deeply, deeply, unfortunate that a member of Congress would, in effect, invite other people who feel that way to say, "Well, I don't have to do it either."

There was a great director who directed a picture that I wrote who barred me from the set quite appropriately and said, "I'm sorry, Jim. When you're directing, you don't need to know everything. You need the illusion that you do." And, you know, and I WOULD be there behind him trying to signal the actors in, you know, in a way I wasn't even aware of.

James L. Brooks

Occasionally one speaks... of signals or signal chains. It should be noted that the word signal means the transmission of signs and hence concerns the very principle of causal order.

Hans Reichenbach

Asking, "How much is it?" is THE BIGGEST buying signal. Telling me, "Your price is too high." is THE SECOND BIGGEST buying signal

There are some people who don't conform to the signals. An ordinary well-regulated locomotive slows down or pulls up when it sees the red light hoisted against it. Perhaps I was born color blind. When I see the red signal -- I can't help forging ahead. And in the end, you know, that spells disaster.

Agatha Christie

Sometimes a certain project will have a smell... It will have a little stench about it. That is a warning signal. You know it's going to be a nightmare. You know they are not going to like it, and it's not worth it.

It's true that non-ionizing radiation lacks the power to have damage. But its damage seems to come from its modulated signal. So every 900 milliseconds, if you have a cellphone in your pocket, it's getting half of that radiation which is getting into you as it seeks the signal from the tower.

I was saying as a joke the other day that I love film editing, I know how to cut a picture, I think I know how to shoot it, but I don't know how to light it. And I realize it's because I didn't grow up with light. I grew up in tenements.
