At two-tenths the speed of light, dust and atoms might not do significant damage even in a voyage of 40 years, but the faster you go, the worse it is--space begins to become abrasive. When you begin to approach the speed of light, hydrogen atoms become cosmic-ray particles, and they will fry the crew. ...So 60,000 kilometers per second may be the practical speed limit for space travel.

In fact, it seems that present-day science, with one sweeping step back across millions of centuries, has succeeded in bearing witness to that primordial ' Fiat lux ' Let there be light uttered at the moment when, along with matter, there burst forth from nothing a sea of light and radiation, while the particles of the chemical elements split and formed into millions of galaxies ... Hence, creation took place in time, therefore, there is a Creator, God exists!

Salvation lies with ourselves, for we live in a world that had been self-generated through the accidental coming together of atoms; particles of matter which move within an infinite variety, but without any overall purpose, goal, or design.

Death cancels everything but truth; and strips a man of everything but genius and virtue. It is a sort of natural canonization. It makes the meanest of us sacred --it installs the poet in his immortality, and lifts him to the skies. Death is the greatest assayer of the sterling ore of talent. At his touch the dropsy particles fall off, the irritable, the personal, the gross, and mingle with the dust --the finer and more ethereal part mounts with winged spirit to watch over our latest memory, and protect our bones from insult. We consign the least worthy qualities to oblivion, and cherish the nobler and imperishable nature with double pride and fondness.

Life is a wave, which in no two consecutive moments of its existence is composed of the same particles.

Faith is universal. Our specific methods for understanding it are arbitrary. Some of us pray to Jesus, some of us go to Mecca, some of us study subatomic particles. In the end we are all just searching for truth, that which is greater than ourselves.

Thus will the fondest dream of Phallic science be realized: a pristine new planet populated entirely by little boy clones of great scientific entrepreneurs free to smash atoms, accelerate particles, or, if they are so moved, build pyramids -- without any social relevance or human responsibility at all.

The mathematician lives long and lives young; the wings of his soul do not early drop off, nor do its pores become clogged with the earthy particles blown from the dusty highways of vulgar life.

To most humans, a universe consisting of particles banging about and doing what they have to do seems cold, barren, and without meaning. Meaning, however, is not something that floats in space, permeating the universe like a nebulous, mystical cloud. ... Meaning arises out of the working of the human mind, and therefore exists only in the human mind. The meaning of existence is whatever you want to make of it.

Electricity is actually made up of extremely tiny particles called electrons, that you cannot see with the naked eye unless you have been drinking.

If I could remember the names of all these particles, I'd be a botanist.
