Author Quotes

There are two competing trends in the world today: one is to create a planetary civilization that is tolerant, scientific, and prosperous, but the other glorifies anarchy and ignorance that could rip the fabric of our society.

Thus the yeoman work in any science, and especially physics, is done by the experimentalist, who must keep the theoreticians honest.

We are not at the end but at the beginning of a new physics. But whatever we find, there will always be new horizons continually awaiting us.

What I do for living, working on something called string theory which we think may answer the fundamental question: Are there other universes? Can you go through a black hole? Can you warp the fabric of space and time and meet your mother before you were born? These are all questions that in principle string theory should be able to answer.

When we sit in a chair, we think we are touching it. Actually, we are hovering above the chair, floating less than a nanometer above it, repelled by the chair?s electrical and quantum forces.

Your grades in school, your scores on the SAT, mean less for life success than your capacity to co-operate, your ability to regulate your emotions, your capacity to delay your gratification, and your capacity to focus your attention. Those skills are far more important?all the data indicate?for life success than your IQ or your grades.

There is a saying among women scientists who attend highly specialized engineering universities, where the girl-to-guy ratio is decidedly in their favor: The odds are good, but the goods are odd.

Time is one of the great mysteries of the universe. We are all swept up in the river of time against our will.

We are now entering a new golden age of neuroscience.

What is the universe? The universe is a symphony of vibrating strings...we are nothing but melodies. We are nothing but cosmic music played out on vibrating strings and membranes.

When we're born, we want to know why the stars shine. We want to know why the sun rises.

There is an old saying: ?If appearance and essence were the same thing, there would be no need for science.?

Time travel and teleportation will have to wait. It may take centuries to master these technology. But within the coming decades, we will understand dark matter, perhaps test string theory, find planets which can harbor life, and maybe have Brain 2.0, i.e. our consciousness on a disk which will survive even after we die.

We believe that black holes collapse to rings hitting very fast. If you follow through the ring you don't die. The mathematics says you fall straight through, perhaps to another universe.

What was God thinking when the universe was created? That?s where we are going with this thing [the super collider]. ? The universe? is quite beautiful? it could have been random? it could have been horrible? that?s what Einstein believed

When you come up with a theory, you fall in love with the beauty the simplicity and elegance of it. But then you have to get a sheet of paper and pencil and crack out all the details. Hundreds and hundreds of pages. Because you have to prove it.

There is no universal consensus as to whether machines can be conscious, or even a consensus as to what consciousness means. No one has come up with a suitable definition of consciousness.

To a physicist, beauty means symmetry and simplicity. If a theory is beautiful, this means it has a powerful symmetry that can explain a large body of data in the most compact, economical manner.

We can now give you a biological reason why cramming doesn?t work, says Dr. Tully. The best way to prepare for a final exam is to mentally review the material periodically during the day, until the material becomes part of your long-term memory. This may also explain why emotionally charged memories are so vivid and can last for decades. The CREB repressor gene is like a filter, cleaning out useless information. But if a memory is associated with a strong emotion, it can either remove the CREB repressor gene or increase levels of the CREB activator gene.

What we usually consider as impossible are simply engineering problems... there's no law of physics preventing them.

When you look at the calculation, it's amazing that every time you try to prove or disprove time travel, you've pushed Einstein's theory to the very limits where quantum effects must dominate. That's telling us that you really need a theory of everything to resolve this question. And the only candidate is string theory.

There is so much noise on the Internet, with would-be prophets daily haranguing their audience and megalomaniacs trying to push bizarre ideas, that eventually people will cherish a new commodity: wisdom.

To a physicist, we have the 'I' word, the I-word is 'impossible.' That's dangerous.

We can summarize electricity, magnetism and gravity into equations one inch long, and that's the power of field theory. And so I said to myself: I will create a field theory of strings. And when I did it one day, it was incredible, realizing that on a sheet of paper I can write down an equation which summarized almost all physical knowledge.

What would happen if history could be rewritten as casually as erasing a blackboard? Our past would be like the shifting sands at the seashore, constantly blown this way or that by the slightest breeze. History would be constantly changing every time someone spun the dial of a time machine and blundered his or her way into the past. History, as we know it, would be impossible. It would cease to exist.
