Particle physics and quantum physics

In summary: Classical particles are described by Newton's laws of motion, while quantum particles are described by the laws of quantum mechanics.

particle physics and quantum physics...

can u tell me some difference between particle physics and quantum physics

You can do some particle physics without quantum physics, and a lot of quantum physics is applied to other things than what is usually called particle physics (like solid state physics, lasers, nuclear physics, quantum chemistry ...).

In fact, particle physics is now rather called "high energy physics" because it studies essentially phenomena at very high particle energies (in the GeV - TeV range).
Quantum theory is a certain conceptual framework in which certain phenomena can be well described, and in fact there is such a framework for high-energy physics which is quantum field theory.

Your question is a bit similar to: what is the difference between Newtonian mechanics and studying airplane engineering. Newtonian mechanics is a conceptual framework that can be used in the studying of airplane designs, but there are aspects of airplane design that don't need much mechanics, and you can do a lot of other things with mechanics outside of airplane design.

"Fotball" is an ancient sport of the Quigly people of the lower Pharnfen River Delta. Football is a sport, although one with multiple region-specific definitions.

:smile:

Does that help as much as you helped the OP? yob vas.

Which is apparently located in an obscure corner of what we now call Norway, based on the results of a Google search for "fotball". :smile:

Killjoy! Actually, I'm guessing "fot" is always a double or triple looooong vowel in any scandinavian language. English has ridiculous rules, Scandinavians love their long vowels.

Sadly, the original people of the Pharnfen River Delta, the Quiglies, died years before the norse people colonized the really cold bits of Scandinavia. Tragic story, but the short version is that the Quigly People were retroactively descended from a future race which has become physically dependant on Big-Macs.

When the fury of the norsemen descended upon them, alas, the Quiglies were driven into the Pharnfen, which was then renamed because it sounded very silly. Go on, say it out loud: Pharn Fen... blegh.

And that's the story of the Quiglies.

Fotball plays a shockingly small role in this I should add.

You're no fun anymore. *pout*

Anyway, I think we all got your metaphor, and for the record it's a good one. I was just feeling silly. :wink:

Did you mean the difference between classical physics and quantum physics? Both include particles, but classical particles are unlike quantum particles.
 

1. What is the difference between particle physics and quantum physics?

Particle physics is the study of the fundamental particles and forces that make up the universe, while quantum physics is the study of the behavior of matter and energy at a subatomic level. In other words, particle physics focuses on the building blocks of the universe, while quantum physics focuses on how these building blocks behave.

2. How are particle physics and quantum physics related?

Particle physics and quantum physics are closely related because the study of subatomic particles requires the use of quantum mechanics. Quantum mechanics is a set of principles and equations that describe the behavior of particles at a subatomic level.

3. What is the Standard Model in particle physics?

The Standard Model is a theory that describes the fundamental particles and forces of the universe. It explains how these particles interact with each other and is considered to be the most accurate description of particle physics to date.

4. What is the role of mathematics in understanding particle physics and quantum physics?

Mathematics plays a crucial role in understanding particle physics and quantum physics. These fields rely on complex mathematical equations and models to describe and predict the behavior of particles and forces at a subatomic level.

5. What are some real-world applications of particle physics and quantum physics?

Particle physics and quantum physics have a wide range of real-world applications, including the development of new technologies such as transistors and lasers. They also play a crucial role in fields such as medicine, where quantum mechanics is used to understand and develop treatments for diseases like cancer.
