Amplify. ...[W]hen we have a device like this and we put it in the dark... it goes click, click... Every once in a while a light particle comes in: a photon. This is a particle in every sense. ...[I]f you have a very weak light... and... you put two cells out, and there's just a few... [photons] coming, then it goes on one or the other... the particle is either here or there. ...It is particles, in every way, whenever you can detect it. ...If we were ten times more sensitive to light, then in the dark, we would see... little flashes, little tiny... dots of light, the nerves would go off just like the photomultiplier, in spots. But the human eye is not quite that sensitive, and it takes 5 or 6 ...photons ...to make one nerve fiber go off. ...So we cannot detect, with the eye, light quite low enough to notice the fact that it comes in the form of rain drops.

Every instrument that has been designed to be sensitive enough to detect weak light has always ended up discovering that the same thing: light is made of particles.

The most sensitive musical instrument is the human soul. The next is the human voice. One must purify the soul until it begins to sound. A composer is a musical instrument and at the same time, a performer on that instrument. The instrument has to be in order to produce sound. One must start with that, not with the music. Through the music the composer can check whether his instrument is tuned and to what key it is tuned.

We represent300 also all multiplications301 of light, which we carry to great distance, and make so sharp as to discern small points and lines; also all colorations of light:

Science is spectral analysis. Art is light synthesis.

You have brought detection as near an exact science as it ever will be brought in this world.” My companion flushed up with pleasure at my words, and the earnest way in which I uttered them. I had already observed that he was as sensitive to flattery on the score of his art as any girl could be of her beauty.

Man as we realize if we reflect for a moment, never perceives anything fully or comprehends anything completely. He can see, hear, touch, and taste; but how far he sees, how well he hears, what his touch tells him, and what he tastes depend upon the number and quality of his senses. These limit his perception of the world around him. By using scientific instruments he can partly compensate for the deficiencies of his senses. For example, he can extend the range of his vision by binoculars or of his hearing by electrical amplification. But the most elaborate apparatus cannot do more than bring distant or small objects within range of his eyes, or make faint sounds more audible. No matter what instruments he uses, at some point he reaches the edge of certainty beyond which conscious knowledge cannot pass.

Science is spectrum analysis. Art is Photosynthesis.

There is no more light in a genius than in any other honest man — but he has a particular kind of lens to concentrate this light into a burning point.

The final result of our researches has widened the class of substances sensitive to light vibrations, until we can propound the fact of such sensitiveness being a general property of all matter.

There is no more light in a genius than in any other honest man—but he has a particular kind of lens to concentrate this light into a burning point.

Up to the present time, in experiments on diffraction there has been no instrument, except a magnifying-glass, which could be used with profit; and this may perhaps be one of the reasons why in this field of physical optics we are so backward, and why we know so little of the laws of this modification of light.

When we consider the fact that the spectroscope has enabled us to make a chemical analysis of the sun, that the telephone has enabled us to hear 2,000 miles and that the x-rays have enabled us to see through flesh and bone, we must admit without reservation, that our power of perception, at some future day, may be infinite. And if we admit this we must admit the essential possibility of the superman.

You can put this another way by saying that while in other sciences the instruments you use are things external to yourself (things like microscopes and telescopes), the instrument through which you see God is your whole self. And if a man's self is not kept clean and bright, his glimpse of God will be blurred—like the Moon seen through a dirty telescope. That is why horrible nations have horrible religions: they have been looking at God through a dirty lens.
