Quotes About Particle

Only light, or other waves that have no intrinsic mass, can move at the speed of light.

It also predicted that the electron should have a partner: an antielectron, or positron. The discovery of the positron in 1932 confirmed Dirac's theory and led to his being awarded the Nobel prize for physics in 1933.

So, one can regard the pair of particles as a single particle moving on a closed loop in space-time. When the pair is moving forward in time (from the event at which it appears to that at which it annihilates), it is called a particle. But when the particle is traveling back in time (from the event at which the pair annihilates to that at which it appears), it is said to be an antiparticle traveling forward in time.

In fact, according to quantum physics, each particle has some probability of being found anywhere in the universe.

We are not about to build particle accelerators that can probe to distances that small. They would have to be larger than the solar system and they are not likely to be approved in the present financial climate.

Heisenberg mostrou que a incerteza na posição da partícula multiplicada pela incerteza em sua velocidade multiplicada pela massa da partícula nunca pode ser menor do que um valor específico, conhecido como constante de Planck.

Stephen Hawking

About the anti em conversion process. I think they've worked out ways to access a particle's bit structure, its self-information. To do that, they'd have to tamper with the so-called privileged channels.

If the all-powerful observer measured a particle and found it at position x, then the particle had to be given a small push by the observer, in the very act of observing. That was Heisenberg's uncertainty principle. You could not tell precisely how much of a push the observer had given the wretched particle, so its future position was somewhat uncertain.

When a particle's wavelength became smaller than the Schwarzschild radius, the disciplines of gravitation and particle physics merged. The minimum mass where this occurred was scarcely a thousandth of a grain of sand. Still, for fundamental particle physics this was incredibly huge, a million million million times the weight of a uranium nucleus.

In 2002, a Scottish journalist, during a dinner meant to be private, absolutely wanted me to react to Stephen Hawking's comments. I said one shouldn't pay too much attention to what Hawking was saying because he was a celebrity but not a specialist of elementary particle theory.

If any particle we haven't yet found lasted long enough and interacted with ordinary matter with sufficient strength that it could possibly affect the physics of everyday goings-on, we would have produced it in experiments by now. One

There are tiny hints in the data that may indicate that this new particle is not just the minimal Higgs.

Then we compare the predicted abundance of such a WIMP with the actual abundance of dark matter.

To a physicist, a "vacuum" is not a machine that cleans your floors, nor does it even necessarily mean "empty space." It's simply "the lowest-energy state of a theory.

They then build detectors that patiently wait for the faint signal of a dark-matter particle passing through and perturbing a nucleus.

Life is strong and fragile. It's a paradox... It's both things, like quantum physics: It's a particle and a wave at the same time. It all exists all together.

Berners-Lee was supremely lucky in the work environment he had settled into, the Swiss particle physics lab CERN. It took him ten years to nurture his slow hunch about a hypertext information platform.

Yes, those ten-billion-dollar twenty-seven-kilometer-long machines are good for more than just finding bosons named after Peter Higgs.

It is good a philosopher should remind himself, now and then, that he is a particle pontificating on infinity.

One may feel inclined to say that Thomson, the father, was awarded the Nobel Prize for having shown that electron is a particle, and Thomson, the son, for having shown that electron is a wave.

I wrote my epitaph: He started out a particle and ended up a wave.

Every subatomic interaction consists of the annihilation of the original particles and the creation of new subatomic particles. The subatomic world is a continual dance of creation and annihilation, of mass changing into energy and energy changing to mass. Transient forms sparkle in and out of existence, creating a never-ending, forever newly created reality.8

Heisenberg's Uncertainty Principle, which states that the electron is a particle but a particle that can be described in terms of waves.
