As you enter this thread bewarned everything you were taught about physics was a lie.

i'm your host Seun LanLege and this is physics with seun lanlege.
*Crowd Applauds*

Let's begin, what is quantum physics? Quantum physics is the study of quantum particles. What are quantum particles? quantum particles are particles that exist at the Planck scale. Quantum particles are also refered to as fundamental particles.

Examples of fundamental particles are the quarks and leptons.

"But what are quarks and leptons?"

They are particles that make up all baryonic matter.

"But what is baryonic matter?"

Baryonic matter is matter that's made up of electrons protons and neutrons.

"But isn't that what all matter is made up of?"

Nope, it isn't.

A proton is made up of quarks, two "up" quarks and one "down" quark.
a neutron is made up two "down quarks" and one "up" quark.

"Now i know this is rubbish"

There are 6 kind(flavours) of quarks - up,down,charm,strange,bottom and top.

"then what are electrons made up of?"

electrons are made up of electrons , electron is a flavour of the general group "lepton" -they are fundamental particles. as explained by the standard model there are also six kinds of leptons - electron, tau, muon,electron neutrino,tau neutrino and muon neutrino.

"My head hurts"

Lol

"Then how are these particles formed?"

The quantum field theory takes care of that. Basically all quantum particles come into existence as a result of fluctuations in their respective fields - example, an electron is formed because of fluctuations in the electron field, "up" quark is formed as a result of fluctuations in the "up" quark field. the same goes for all quantum particles.

"Wait if quantum particles are fluctuations in their respective fields, and atoms are made up these fluctuations doesn't that mean that all matter is unstable?"

Technically

"So there's a possibility i can disappear into nothing"

not really that's where Bosons come in, a type of boson called the gluon holds the quarks that make up atoms together - causing them to remain stable. if the gluon field disappeared, 80% of baryonic matter would disappear with it. Bosons are force mediators, think of them as a power outlet for their respective fields. The gluon channels the gluon fields which mediate the "strong" force which holds quarks together.

there are four fundamental forces - gravitational, electromagnetic, strong nuclear, and weak nuclear. The gravitational force is a classical field, therefore it doesn't affect the quantum world. the electromagnetism is mediated by the photon.
a little side note all quantum particles have mass, the photons and neutrinos have no mass but the meson does(a hadronic particle made up quark-antiquark pairs held together by the strong force). The electron also possesses mass. Quantum particles(Fluctuations in their respective fields) gain mass when they interact with the higgs field by gaining and losing something called "weak hyper charge". Fluctuations in the higgs field create the higgs boson.

"hmm, cool what is an aniquark"

an anti-quark is also a fundamental particle its basically a quark with a negative charge. Remember E=MC^2?

"yeah"

do you know what it means?

"it means E equals m * c^2"

lool, nope it means energy = mass multiplied by the square of the constant of proportionality. it means baryonic matter can be created from pure energy, but in this form of matter creation matter and anti matter are both created.

"Wait you keep talking about fluctuations in fields, what causes these fluctuations?"

As far as anybody can tell, nothing.

"That's impossible"

Well, in the quantum world classical logic is rendered useless, have you heard of the famous double slit experiment?

"no, what did the experiment prove"

It proved quantum physics is crazy and when dealing with it abandon all pre-conceived logic, i've forgotten the year but in 1960's(thereabout) physicists wanted to understand the photon. so they placed a slit in front of a detector,and fired photons at the slit. of course the detector recorded that it a small area was hit with the photon, so they went crazy and put two slits and when they fired the photon - the detector recorded that a large area was hit like it was a wave. Scientists where baffled, it was like the proton had a mind of it's own - if there was only one slit the detector would read a photon. If there were two - the detector would read a wave. A lot of scientists tried to explain this wave-particle duality - Heisenberg proposed that quantum particles exist in all possible states till it interacts with another system in which it's "wave function collapses" and then it returns to being a photon.

we will discuss this at length in episode II of quantum physics.

Bye for now.

Now that I've recovered from my sci-gasm I would like to say that I'm very impressed with your explaining skills here, you've dumbed quantum physics down to something a secondary school student can understand when teachers struggle to explain ordinary physics.

Now I just have one question: When energy forms baryonic matter, you said it also forms antimatter, now why is that we have far more matter than antimatter in observable space?

Fine job@ op

this question shows you actually read and understood the post, well astrophysicists don't really know why this is so. Studying anti-matter would help us understand it's absence, problem is if matter interacts with anti matter it instantly vaporizes into pure energy and mesons. So creating and maintaining it is really difficult, therefore the cloud of ignorance that currently covers anti-matter.

Thanks a lot.

Wow..... This is................ Wonderful!!!!!!Teempakguy, a quantum physicist is in the building.

My question now is: where does light fit in Light is neither baryonic matter nor a wave.
It"flunctuates" between the two. Where is it placed in quantum physics


I'm also wondering where Schrodinger's cat analogy where the cat is alive AND dead fit in quantum physics. And why Einstein's statement "God does not play dice" is hated by quantum physicists.

OP, we need your type in the science and technology section. Once again, Nice job Ccjoshuabase,prOton.

basically no one knows what the photon's true state really is, but that's how the quantum reality works - nobody really has a true state or position(remember Heisenberg's uncertainty principle?) quantum particles are super positioned in all possible states until their wave function collapses(also known as decoherence) and they can only occupy one physical state.

Schrödinger's cat is a thought experiment that tries to explain quantum super positioning(occupying all possible physical states at once) i'll talk about it in a later topic.

Huh. Ok. I await the Part 2

"God does not play dice with the universe"

Was as a result of Einstein's frustrations with the double slit experiment, it was supposed to shed light on what photons really were (punintended) instead it just frustrated physicists world wide.

If anything, the experiment proved that the universe was non-deterministic and entirely probabilistic.

Beautiful. I would like to be tagged each time there's an episode out. In fact let me follow you to make things simpler.
