Sentences with phrase «quantum mechanics»
Quantum mechanics is a branch of physics that helps us understand how very small things, like atoms and particles, behave and interact with each other. It studies the strange and surprising properties of these tiny things, like their ability to exist in more than one state at the same time or to be connected across large distances. It provides a different set of rules and principles from classical physics, helping scientists explain the behavior of these small particles and build things like computers and lasers. Full definition
The trouble is, very few experiments have been performed that can rule versions of quantum mechanics in or out.

So you have the same problem in quantum mechanics as in relativity.
The effort to reconcile general relativity with quantum mechanics always hits one snag: gravity.
In their view, we do not see quantum effects in the every day world because the act of observation changes everything, fixing the many possibilities allowed by quantum mechanics as one.
In the 1980s, theorists realised that a computer based on quantum mechanics had the potential to vastly outperform ordinary, or classical, computers at certain tasks.
We tend to accept relativity and quantum mechanics as great ideas without understanding much about them.

In condensed matter physics, people use quantum mechanics to describe the states of a large collection of particles.
For decades, physicists seeking a solid foundation for quantum mechanics have been proposing new interpretations of its math.
The problems of quantum mechanics did not yield to the kind of infinitely intelligent simple arguments that marked his best work.
«That sounds to me like saying we don't understand this basic psychological phenomenon, we don't understand quantum mechanics, therefore the two must be related,» he says.
To look deeply into quantum mechanics is to look beyond the bounds of ordinary experience.
Finally, the data confirm a deep connection between quantum mechanics and general relativity.
Some physicists deny that quantum mechanics describes any sort of objective reality.
But apparently you believe in the fuzzy math of quantum mechanics which develops «spirit worlds» to achieve an answer where said steps for achieving said state has no real meaning.

There are serious problems as to what quantum mechanics means, and I will summarize them briefly.
With the new rules, physicists can replicate most of the predictions of standard quantum mechanics.
The laws of quantum mechanics allow pairs of electrons to «tunnel» through the barrier only very occasionally — helping the team to isolate and control the pairs as they slowly break out.
The rules of quantum mechanics say that those electrons must return back to the lower energy level.
So it seems as if quantum mechanics doesn't care about space and time.
The equations of quantum mechanics work very well; they just don't seem to make sense.
Basically, quantum mechanics applies on atomic scales, and general relativity applies on big scales.

A good way of looking at this is to study quantum mechanics.
Actually, if you take the time to read up on some basic quantum mechanics, they do.
The discovery of quantum mechanics took the story of nothing further still.
Before quantum mechanics arrived on the scene, physicists believed that the laws of physics could be used to determine the future of the universe and every object within it.
While quantum mechanics primarily applies to the smaller atomic regimes of matter and energy, some systems exhibit quantum mechanical effects on a large scale.

The work shows that the laws of quantum mechanics hold up as expected on a large scale.
According to general relativity, there is also no limit to how small they can be (although quantum mechanics suggests otherwise).
The rules of quantum mechanics give atoms discrete ways to absorb energy in collisions or lose it to photons.
Taking a step back, this is the first time we've had a chance to build an entirely new field in physics since quantum mechanics about 100 years ago.
The new quantum mechanics opens the door to that question.
