Particles Quotations

The world is not made up of particles and waves and beams of light with a definite existence. Instead, the world works in a much more exploratory way. It is aware of all the possibilities at once and trying them out all the time. That is a hard thing to picture.

As the size of cyclotrons increases and faster particles are produced, a difficulty arises due to the relativistic increase of mass of the particle.

A linear accelerator has the advantage that no magnet is required and that its cost should not rise much more steeply than with the energy of the particles required.

Particles were coming out of the lithium, hitting the screen, and producing scintillations. They looked like stars suddenly appearing and disappearing.

When we breathe it in, soot can interfere with our lungs and increase the risk of asthma attacks, lung cancer and even premature death. The smallest particles can pass into the blood stream and cause heart disease, stroke and reproductive complications.

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.

Physical studies of DNA had, of course, been under way for some years before analysis of virus particles began.

When I received my B. S. degree in 1932, only two of the fundamental particles of physics were known.

Virus particles contain single molecules of nucleic acid.

The minute those two little particles inside a woman's womb have joined together, billions of decisions have been made. A thing like that has to come from entropy.

Having those extra dimensions and therefore many ways the string can vibrate in many different directions turns out to be the key to being able to describe all the particles that we see.

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.

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.

I do not keep up with the details of particle physics.

Investigating the forces that hold the nuclear particles together was a long task.

Just as the system of the sun, planets and comets is put in motion by the forces of gravity, and its parts persist in their motions, so the smaller systems of bodies also seem to be set in motion by other forces and their particles to be variously moved in relation to each other and, especially, by the electric force.

That the divided but contiguous particles of bodies may be separated from one another is a matter of observation; and, in the particles that remain undivided, our minds are able to distinguish yet lesser parts, as is mathematically demonstrated.

Quarks came in a number of varieties - in fact, at first, only three were needed to explain all the hundreds of particles and the different kinds of quarks - they are called u-type, d-type, s-type.

We know that if supersymmetric particles exist, they must be very heavy; otherwise we would have spotted them by now.

There is no physical law precluding particles from being organised in ways that perform even more advanced computations than the arrangements of particles in human brains.

I think the discovery of supersymmetric partners for the known particles would revolutionize our understanding of the universe.

My favorite memory in the barbershop was watching the hair fall. Little particles would fall and I would make designs out of it.

Neutron stars are incredible laboratories for learning about the physics of the fundamental particles of nature, and this pulsar has given us an important new limit.

Now we know that these small particles are really dangerous, so we need to adapt to that new knowledge.

People want to know about what's going on with what's in the universe, what are particles like, what are the basic rules of nature. It's a lot of curiosity out there.

There are other families of particles out there that can form massive compact objects.

Measurements of the specific ionization of both the positive and negative particles, by counting the number of droplets per unit length along the tracks, showed the great majority of both the positive and negative particles to possess unit electric charge.

Silicon in its bulk format we all know is not an efficient emitter but when you get down to the quantum-confined sizes, you get very different effects. For the smaller sized particles you can get blue emission and for the larger particles you can get red emission. By having a film of these devices, you can electrically stimulate them.

Capturing particles from a comet as it whizzes by is a way of looking back in time.

We think comets make up a huge amount of stuff out in the solar system. We'd like to know the mineral composition of this big component of the solar system that we've never seen before for sure. Various particles have been measured that have been inferred to be from comets, but nobody's sure. This would finally provide some ground truth.

Hail is dirt particles that water forms on and freezes. The ionic pressure from the cannons keeps it from forming when we've got storms. They go off, and we don't have hail. We've had hail out on the highway in front of the plant, but not at the plant.

Whatever benefits are reaped from the improvement in one car are overwritten by the five cars that give out harmful particles and gases.

Laboratory experiments, field observations and atmospheric modeling calculations have now established that chemical reactions occurring on PSC particles play a central role in polar ozone depletion.

Particles of the allergen -- in this particular case, peanuts -- are small enough to actually float in the air, ... If they land on someone who is allergic, land in their eyes or in their nose, they can cause them an actual allergic reaction.

Particles that are micron sized interact with sunlight more efficiently, so it appears that would cause an impact on climate from these particles left in the upper atmosphere.

Our mission is called Stardust, in part because we believe some of the particles in the comet will, in fact, be older than the sun.

Last Sunday, after seven years in space traveling nearly three billion miles, Stardust landed in the Great Salt Lake Desert with a treasure from when the solar system formed 4.6 billion years ago. We should have more than one million particles larger than one micron in diameter.

Janus particles may be useful for directed drug delivery.

I think there is no chance that the blue ring is caused by geyser activity. We don't know what the composition of the particles is.

I was having a conversation with my father and he was talking about this thing - strangeness and charm. It's actually the name of the two smallest particles that there are when you split the atom, so I wrote a song around it. I even managed to fit the word 'hydrogen' in there. Isn't that a nice thing for scientists to call them though?

It exceeded all of our grandest expectations. We should have more than 1 million particles larger than 1 micron in diameter.

I think you have to deal with the confused situation that we're faced with by seizing on the glimpses and particles of life, seizing on them and holding them and trying to make a pattern of them. In other words, trying to put a world back together again out of its fragmentary moments.

It blows air across your body and dislodges microscopic particles that you may have been in contact with, thereby screening for explosives.

The prediction was that we would get a dozen particles larger than human hair size and one particle a little bit larger than a millimeter.

We have always stressed in this mission that we are stardust. Our planet and even our selves have a direct relationship to the particles we brought back.

We found a dramatic decrease in particles. There is something like a 70 percent decrease in particles in the pub and that makes it quite similar to outdoor air in Dublin, which is quite good.

We hope that one of these new particles that may get created will be this dark energy particle.

(The extra headroom) gives us easy access to clean the dust, grain particles and fines from underneath the drying floor. It also helps to keep insects out during storage.

The problem with the classical theory is that you could use any combination of particles to make the black hole -- protons, electrons, stars, planets, whatever -- and it would make no difference. There must be billions of ways to make a black hole, yet with the classical model the final state of the system is always the same.

We hope to eventually be able to predict major events on the sun and to evaluate the impact of magnetic particles hitting the earth.

We are collecting the actual building blocks the solar system was formed from 4.5 billion years ago. We believe that the particles have a lot of information stored in them.

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.

…In the end we are all just searching for truth, that which is greater than ourselves.

What the string theorists do is arguably physics. It deals with the physical world. They're attempting to make a consistent theory that explains the interactions we see among particles and gravity as well. That's certainly physics, but it's a kind of physics that is not yet testable.

What physics tells us is that everything comes down to geometry and the interactions of elementary particles. And things can happen only if these interactions are perfectly balanced.

We believe those particles are inhaled and that's how people become infected.

Unity of the different forces and particles is achieved because they all come from different kinds of vibrations of the same basic string.

We're talking about microscopic particles that are easily transferred.

We're the first to be able to tell you both the location of the particles and what kind of particles they are.

These new findings are significant because they show that our technique is effective in finding ice when it is on the surface and that we can therefore firmly conclude that most of the water vapor that escapes from comets is contained in ice particles found below the surface.

The standard model of particle physics describes forces and particles very well, but when you throw gravity into the equation, it all falls apart. You have to fudge the figures to make it work.

The particles are so small they should not last very long. You couldn't have the E ring just sit there for the age of the solar system. It had to be regenerated somehow.

The particular features of the photographic method of detecting atomic particles enabled us to establish the existence of transient forms of matter which had escaped recognition by other methods.

The universe was quiet, vacuous. Very slowly, a weak attraction brought them together, creating a collision that made particles and energy.

you're just a collection of particles that have come together by chance and by natural selection.

This is the first time anyone has been able to look at the cancer risk associated with single alpha particles going through cells, and what we saw was the effects were in fact rather less than expected,

In 1956, when I began doing theoretical physics, the study of elementary particles was like a patchwork quilt. Electrodynamics, weak interactions, and strong interactions were clearly separate disciplines, separately taught and separately studied. There was no coherent theory that described them all.

Indeed, the history of 20th century physics was in large measure about how to avoid the infinities that crop up in particle theory and cosmology. The idea of point particles is convenient but leads to profound, puzzling troubles.

I'm confident that the particles will be the most primitive stuff we've ever had on Earth.

It's not at all exotic. Every time you look at the water in a nuclear reactor, the bluish glow you see is radiation produced by charged particles moving faster than the speed of light in the water.

But through my interests in electron motion in vacuum tubes I discovered a need to describe trajectories of moving particles with equations.

These particles can damage the cells in the lining of our lungs and produce lung cancer.

They wanted to fire one X-ray photon at a hydrogen molecule, knock both electrons back, and the two nuclei would explode apart. Then, they wanted to catch all four particles and figure out the orientation of the molecule in space: how far apart were the nuclei, where did the electrons go for that orientation and what were their distances." ()

It'll take treated effluent and run it through a cloth filter process and remove even minute particles to give us a very, very clean effluent.

It was miserable. Dries out your eyes. Imagine someone taking a blow dryer to your face, but cold. And all the shrapnel, like the particles of dirt flying in front. Wind is the hardest condition to play in, even worse than snow if you can believe that.

The increased momentum of American life, both in its particles and its mass, unquestionably has a considerable moral and social value.

The fluorocarbon particles are pretty small, and you don't want those sitting in your lungs.

The filter does help to reduce the ozone the product emits. But it still -- from our tests -- didn't perform well in removing particles from the air.

Each of the satellites in the solar system are pummeled by interplanetary dust particles, or meteoroids which are marble-sized or millimeter-sized objects, ... When those hit a satellite, or moon, at high speeds, they slam into the surface and blast a crater, and all sorts of particles fly off. That's what is happening at Ganymede, and we think that's what's happening at all the satellites in the solar system.

(The research) will involve looking at particles that were kept in the far reaches of our universe in a deep freeze since the beginning of our solar system.

It is the compaction of everyone driving on the sand. These completely microscopic particles just don't settle.

This was a dangerous, uncontrolled reaction because the magnesium particles were spilling out of the dumpster and releasing gas. If our inspectors hadn't intervened, this dangerous conduct could well have led to a serious fire or explosion.

We fully expect some of the comet particles to be older than the sun.

Being able to develop drugs to raise levels of good cholesterol depends on knowing more about the how and where the particles are formed. These animals provide the first tools to address these questions.

Subatomic particles do not just sit around being subatomic particles. They are beehives of activity.

Isolated material particles are abstractions, their properties being definable and observable only through their interaction with other systems .

Any two particles in the universe attract each other through the gravitational interaction.

On the big Bang theory: For every one billion particles of antimatter there were one billion and one particles of matter. And when the mutual annihilation was complete, one billionth remained - and that's our present universe.

Poetry implies the whole truth, philosophy expresses only a particle of it.

I haven't a particle of confidence in a man who has no redeeming petty vices whatsoever.

Each particle is a microcosm, and faithfully renders the likeness of the world.

Any particle in this universe can change in relation to any other particle; but take the whole universe as one.

The law of attraction which holds good for the heavenly bodies also holds good for the smallest particles.

Which came first — the observer or the particle?

Once we were particles of Light, now we are Beings of Light, radiating Love.

When you trace a particle back to its origins, you find that it's nothing but pure energy. All of us come from this energy field.
