Quantum Mechanics

[Msubulldogfan1]

Is this an interest to anybody here?

There’s some crazy **** that happens at the atomic/sub-atomic level.

Wave function is really hard for me to comprehend.

Engie is your man.

 

[MagicDawg]

The fact that it's so complex is what gives me hope that there's something simpler behind it.

 

[Msubulldogfan1]

Electrons spin around the nucleus of an atom about 7 quadrillion times a second. I’m like 17 dude, how!?!?

 

[Msubulldogfan1]

And then you have quarks, upward facing quarks, downward facing quarks. The nature of reality is bizarre. Those things are incomprehensibly small.

 

[Shmuley]

That's a dark matter.

 

[Msubulldogfan1]

Dark matter is an interest subject. Physicist predicted it was the result of the “wimp” but I guess it’s starting to look like that doesn’t exist so they are back to square one.

I'm interested in it in the same way I'm interested in higher level math. I like to see the the "popular mechanics explanation" that si probably too over simplified if not just incorrect to begin with, but not interested enough to do the painful work of understanding it. Wish I had gone beyond Physics III and past DE and Cal IV in college, when I might have had the time and inclination to try to understand it. But of course at the time I was a dubmassed college student looking to minimize the work required outside of my required classes, and didn't take advantage of the opportunity I had to study stuff that was interesting to me. God forbid college me spend one less day a week hungover because I had to study for an elective.

This second guessing yourself will pass and when you get to my age the only mechanics you'll care about are the ones who can fix your electric car. **

Yes. Very interesting to me. Wish I knew more about it. My physics phd buddy says no one really understands it as far as what is actually going on.

I’m interested. I’ve also read a little bit about string theory. One of the questions that really 17’s with my mind is what are quarks made of and how could they not be made of anything? Everything has to be made of something. And if a quark is made of something then what is that made of? It’s like realizing that there is an infinity between natural numbers. You can divide a number forever. It’s some trippy, mind blowing stuff.

 

[Msubulldogfan1]

They know what happens through predictions.

How it happens is the question.

I’m reading Sean Carrols “something deeply hidden” currently. Might pick up NDTs book astrophysics for those in a hurry, or something similar.

Quantum level mechanics? Bold.

Seriously, I feel I'm surrounded by a neanderthall society who have enough trouble figuring out basic economics, voting tabulation, and handicapped parking

And for 17 sake people, put your 17in garbage in garbage cans, then let's talk energy quantization

 

[Msubulldogfan1]

Why the 17 will an electron go through two slits in a barrier when not being measured, but only one slit when measured.

That connects the many worlds theory, that is really a mind 17, and it’s a legit trying to be put in the books theory.

You sound angry. Angry people on social media is the problem.

 

[PirateDawg]

Boson man, the Boson is the answer that we've been looking for! Angry people do not affect it - it affects them. Social media is just background noise like this forum. Boson opens the way to the universal grid that vibrates and affects everything in the universe.

If it makes you feel better, I did go past DE and Cal IV and my interest level still doesn't really want to know anything above Popular Mechanics level stuff. If I never work an equation or theorem again in my life, I'll somehow muddle along...

 

[T-TownDawgg]

That’s what my daughter says. She saw the “angry dad” Simpson’s episode and said “hey look it’s Dad”. She took a picture of the look I shot her and posted on her Instaface page

 

[PineGroveBully]

Believe it or not I actually googled quantum physics over the weekend to try and understand little. I was not a science guy in school but always had that curiosity, one reason I love space so much. I follow posts on Neil deGrasse Tyson’s page and a lot of it is so interesting but my 20 yr old brain might could wrap my mind around it but my 38 year old brain says no dice. But I never took physics in school, but I actually made a 25 on the English portion of ACT along with the other 3 sections so I figured I could figure it out, I was wrong.

To me, Quantum Entanglement is one of the wildest things there is in quantum physics. There are teams all over the world working with quantum entanglement in hopes of creating reliable quantum computers. It's only a matter of time before one or more of them succeed and when they do our world is going to change very very rapidly. We'll make a huge evolutionary step and AIs will become a very very real thing.

 

[Baddmann]

The possible application of Quantum Mechanics is what I have been most interested in recently. There have been some breakthroughs that could really be an upgrade to computer processing and cybersecurity.

1. Quantum Entanglement: (Einstein's "spooky action at a distance") as security for sharing information between 2 bodies is unbreakable. This concept is starting to see some light for practical applications in the near future (3-5 years?). Essentially unhackable encryption - or if if a hacking attempt occurs, you will know it instantly. The very act of trying to read the entangled particle destroys the entanglement.

2. Quantum Processing: This is still early, but it is showing promise. The Quantum Error correction and wrangling qubits is the current challenge. I think IBM is the current leader with 65 qubits. If they can get to 1000, that will be a gamechanger. (I read somewhere that around 200 entangled qubits would smoke any current supercomputer in processing...)

 

[UpTheMiddlex3Punt]

There may or may not be a quantum mechanics expert here. This thread is wavefunction collapse.

 

[Hugh's Burner Phone]

Booking a room at the holiday inn express tonight. Will revisit thread tomorrow.

We view it from a universe bound by gravity. Electrons exist at a scale where there is no gravity, just electromagnetic impulses. You can't accurately observe something that is bound by a different set of physical laws than you.

AI is a real thing right now.

AI another very interesting topic with a lot of layers. We have algorithms in super computers that we really have no idea how they work.

One interesting fact is AI does better when it’s located in a body, than in a computer. So have a body might be instrumental in consciousness.

But it is being accurately observed.

The implication is that the electron is actually in two different states simultaneously. According to QM, we all have a wave function, if I understand it right, which blows my mind.

It’s entanglement that locates the electron to a concentrated point, right?

 

[Maroon Eagle]

I’m also a fan of Occam’s Razor.

 

[Snave]

This might be my favorite thread. It's always fascinating to see classical physics rules get violated at the subatomic layer.

 

[Msubulldogfan1]

I’m also a fan of Occam’s Razor.

and that relevant to QM how?

 

[thatsbaseball]

OK. When someone finally makes a break through and this stuff can be put to some practical use affecting our day to day lives, how will it first show up ?

Extremely fascinating subject and it’s hard to find people to discuss deep topics like this.

That’s when I had the brilliant idea to bring it to SPS.

 

[MStateU]

Who else reads books about submarines?

Quantum Cryptography using Quantum Key Distribution is offered by a few companies now.

[Villagedawg]

Well, they already have.

Sensors in digital cameras.
Transistors using silicon semiconductors (computers)
LED lights

I’m sure there’s more.

AI is a real thing right now.

Artificial General Intelligence (when machines think, learn and decide on their own) isn't a thing right now. Current AI's just execute instructions provided to them by humans. It's like playing vs the computer in a video game. The computer isn't making logical decisions on how to defeat the player, it's just executing pre-programmed instructions based upon conditional statements that are interpreting input parameters.

Won’t there always be pre-programmed instructions though?

Super computers do things we don’t program to do.

For example, we aren’t able to program a computer to consistently recognize human faces. But when can program a computer with a set of algorithms that enables it to learn, and become much more efficient at recognizing human faces.

 

[PirateDawg]

Very interesting applications. I have been reading and watching videos on the Boson and the research they're doing at Fermilabs. If you go to Youtube and look them up you can subscribe and get the latest on their research. It is a worldwide effort but Fermilabs has the largest contingent for any country involved. Fun stuff!

Logical first step.

The theory is that true AGI computers will create their own instructions and algorithms for tasks that we never intended the computer to do as opposed to your example of facial recognition software that was very much designed for that specific purpose. True AGI is not here yet, but unfortunately it seems inevitable.

 

[T-TownDawgg]

True AGI is not here yet, but unfortunately it seems inevitable.

This reminds me of Einstein's body of work in atomic energy being used to build something, and then he spent the rest of his life lobbying to abolish it's inevitable product.
