“A happy man is too satisfied with the present to dwell too much on the future.”

“A man should look for what is, and not for what he thinks should be.”

“A person who never made a mistake never tried something new.”

“Anger dwells only in the bosom of fools.”

“Any intelligent fool can make things bigger and more complex… It takes a touch of genius – and a lot of courage to move in the opposite direction.”

“Any intelligent fool can make things bigger, more complex, and more violent.

It takes a touch of genius — and a lot of courage — to move in the opposite direction.”

“Any man who can drive safely while kissing a pretty girl is simply not giving the kiss the attention it deserves.”

“As a human being, one has been endowed with just enough intelligence to be able to see clearly how utterly inadequate that intelligence is when confronted with what exists.”

“Coincidence is God's way of remaining anonymous.”

“Compound interest is the eighth wonder of the world. He who understands it, earns it… he who doesn’t pays it.”

“Don’t think about why you question, simply don’t stop questioning. Don’t worry about what you can’t answer, and don’t try to explain what you can’t know. Curiosity is its own reason.

Aren’t you in awe when you contemplate the mysteries of eternity, of life, of the marvelous structure behind reality? And this is the miracle of the human mind — to use its constructions, concepts, and formulas as tools to explain what man sees, feels and touches.

Try to comprehend a little more each day. Have holy curiosity.”

“Education is what remains after one has forgotten what one has learned in school.”

“Everyone is a genius. But if you judge a fish by its ability to climb a tree, it will live its whole life believing that it is stupid.”

“Everything should be made as simple as possible, but not simpler.”

“It took quantum theory to reconcile how both ideas could be true: photons and other subatomic particles – electrons, protons, and so forth — exhibit two complementary qualities; they are, as one physicist put it, 'wavicles'.

To explain the idea physicists often used a thought experiment, in which Young’s double-slit demonstration is repeated with a beam of electrons instead of light. Obeying the laws of quantum mechanics, the stream of particles would split in two, and the smaller streams would interfere with each other, leaving the same kind of light- and dark-striped pattern as was cast by light. Particles would act like waves.

In 1961, this idea was actually tested with electrons, and it worked as expected. Elementary particles, chunks of stuff like little billiard balls, behave like waves, provided that you aren’t looking. This can be demonstrated easily even if you shoot a single photon one at a time through a double-slit apparatus.

However — and this is the frosting on the quantum measurement problem — those very same chunks of stuff behave like particles when you do look at them. Technically, the process of looking is called gaining 'which-path' information, in which you learn which path a photon took as it traveled through the double-slit apparatus.

To repeat: If you know that it goes through the left slit or the right slit, typically determined using a detector placed behind each slit, then the photon will behave like a particle. But if you don’t know, then it will behave like a wave.

The experiment we conducted took advantage of this intriguing effect. It was based on two assumptions:
(A) If information is gained — by any means — about a photon’s path as it travels through two slits, then the quantum wavelike interference pattern, produced by photons traveling through the slits, will 'collapse' in proportion to the certainty of the knowledge obtained.

(B) If some aspect of consciousness is a primordial, self-aware feature of the fabric of reality, and that property is modulated by us through capacities we enjoy as attention and intention, then focusing human attention on a double-slit system may extract information about the photon’s path, and in turn that will affect the interference pattern.”
