Quotes About Particles

Charged particles can scatter light by absorbing and reemitting it (a). Light can scatter off light only by the mediation of charged particles-the virtual particle-antiparticle pairs fluctuating in the vacuum (b). This effect is very small; there is no experimental proof yet.

The photon itself, the carrier of the electromagnetic interaction, is electrically neutral. That means all interactions among photons proceed through the mediation of other, electrically charged particles.

In summary, there is nothing much to the conversion of energy into matter and vice versa. The first actual transformation of light into matter without the participation of other particles, accomplished in 1997, generated a huge response from the media. The technical problems encountered in order to achieve this goal were enormous-but there was nothing particularly new in the result itself. The same holds for the recent assembly of antimatter from antiparticles.

Dick Feynman was a genius of visualization (he was also no slouch with equations): he made a mental picture of anything he was working on. While others were writing blackboard-filling formulas to express the laws of elementary particles, he would just draw a picture and figure out the answer.

Technically you need the extra dimensions. At first people didn't like them too much, but they've got a big benefit, which is that the ability of string theory to describe all the elementary particles and their forces along with gravity depends on using the extra dimensions.

Your chemistry high school teacher lied to you when they told you that there was such a thing as a vacuum, that you could take space and move every particle out of it.

You have that one basic string, but it can vibrate in many ways. But we're trying to get a lot of particles because experimental physicists have discovered a lot of particles.

However, it has been found that even the elementary particles can be created, annihilated and transformed, and this indicates that not even these can be ultimate substances but, rather, that they too are relatively constant forms, abstracted from some deeper level of movement.

What makes them even more astonishing is that there is compelling evidence that the only time quanta ever manifest as particles is when we are looking at them.

The discovery that light elements could be disintegrated by artificially accelerated particles gave an additional impetus to development work on the various methods of producing them.

The postdoc explained to me how to distinguish different sorts of particles on the basis of the amounts of energy they deposited in various sorts of detectors, spark chambers, calorimeters, what have you.

When one studies the properties of atoms, one found that the reality is far stranger than anybody would have invented in the form of fiction. Particles really do have the possibility of, in some sense, being in more than one place at one time.

There is a] growing conviction that quantum mechanics is at root a theory not of tiny particles and waves but of information and its causative influence. It's a theory of how much we can deduce about the world by looking at it, and how that depends on intimate, invisible connections between here and there.

In fact, these possibility collapses happen at the level of elementary particles, but they happen in just the same way: one moment several things are possible, the next moment only one thing happens, and the rest don't exist. Except that other worlds have sprung into being, on which they did happen.

Perhaps some particles move backward in time; perhaps the future affects the past in some way we don't understand; or perhaps the universe is simply more aware than we are.

Perhaps some particles move backwards in time; perhaps the future affects the past in some way we don't understand; or perhaps the universe is simply more aware than we are. There are many things we haven't yet learned how to read.

Music isn't much different now from what it was when we hit the dance floor. This means something. We found something universal. We bottled that desire, then released it into the airwaves. The sounds hit your body, and you move. We are in those particles that send you. We are in that music. Dance for us, Tariq. Feel us there in your freedom.

Like all things in the universe, we are destined from birth to diverge. Time is simply the yardstick of our separation. If we are particles in a sea of distance, exploded from an original whole, then there is a science to our solitude. We are lonely in proportion to our years.

Given that you desire to change things in your life much bigger than particles, how long do you maintain your observation and how much mental power do you invest in observing those things?

LifeParticles are the particles of Nothingness that have attributes of being and nonbeing, and the particles of energy and consciousness, which are the essence of Life.

Reality ground my expectations into microscopic particles.

In string theory, all particles are vibrations on a tiny rubber band; physics is the harmonies on the string; chemistry is the melodies we play on vibrating strings; the universe is a symphony of strings, and the 'Mind of God' is cosmic music resonating in 11-dimensional hyperspace.

Other branes might be parallel to ours and might house parallel worlds. But many other types of braneworld might exist too. Branes could intersect and particles could be trapped at the intersections. Branes could have different dimensionality. They could curve. They could move. They could wrap around unseen invisible dimensions. Let your imagination run wild and draw any picture you like. It is not impossible that such a geometry exists in the cosmos.

All of the lightest stable quarks and leptons have heavier replicas. No one knows why they are there, or what they are good for. When physicists first realized that the muon, a particle first seen in cosmic rays, was nothing other than a heavier version of the electron (200 times heavier), the physicist I.I. Rabi asked, "Who ordered that?
