Message from Deleted User in MacGuyver - Skills & Academics #stem
@Deleted User It's from "Pattern Recognition and Machine Learning" by Timothy Bishop. I was just glancing through it while waiting through the train. For my job (datascientist) I like to have at least a high level acquaintance with these things in case they come up.
Gattaca is about an untermench kike selfishly subverting the social order to gain privileges he doesn't deserve.
It's a beautiful story about self sacrifice and the struggle of humanity for greatness
Study the STEMs so you wont catch the poors
I want to start picking up some IT certs to make a career change. Any advice on where to start learning what I need for CompTIA A+? Any good free resources, or should I just pick up a book from Amazon?
I would say just get started. Setup an old PC as a Windows Domain Controller or something like that. I don't know much about IT or Windows but I got into web development by just doing it, picking up languages and technologies at home as a hobby and then at work as needed.
I suggest getting the a+ and then applying for Help Desk jobs. You can then chat with the Network, Security, System Admin, and Development teams to see what direction you want to go.
Am I a Neanderthal or a homo sapien? What is a black person?
just noticed this. I have a degree in physics, minor in math, so I can answer questions about that. I don't always check this, so feel free to tag me.
If gravity affects time as well as space, and the Big Bang is the mother of all gravitational events, is it true that there may be some places in the universe that the Big Bang, which to us happened 13 billions years ago, actually just happened an instant ago?
Don't know a lot about general relativity to be honest. That's a good question. I don't think the big bang itself would be a factor, but if something has been moving relative to us for a long time and then slowed down to catch up with us, it would be younger. Likewise if an object spent a lot of time in a high gravity environment, it would be younger. Also since it takes a finite amount of time for light to travel, when we look at galaxies very far away, we're looking back in time.
The weird thing is that the galaxy can expand faster than the SOL which is hard to wrap my head around but definitely goes to the temperaneousness of the Big Bang for certain places in the universe.
I had not heard that one.
I am a layman, so I will defer to the experts. But my understanding is that only physical objects are bound by relativity and SOL rules. The universe itself is not physical so the SOL rules don't apply and I have read in multiple places that the universe does/did expand faster. How that jives with time and space is something cool to think about.
The concept makes sense - spacetime itself not having mass and therefore not being bound by the same rules as things that have mass
Light has no mass though. A lot of theoretical physics seems to be a group of lazy (((people))) that made up ideas to make their equations work
Well, as I understand it, the modern view of light isn't so much that its a particle/wave as it is something that exists in spacetime itself. Kind of like the color of my shower curtain. I shake the shower curtain and the color ripples.
But there's no, err, shooting, of a separate particle, like a canon.
If you want to watch a show that will blow your minds, check out Through The Wormhole With Morgan Freeman (I know, but he is just the narrator). The show is a science doc that focuses on these questions and interviews top scientists from around the world.
It primarily focuses on the convergence of physics and philosophy.
I like Morgan Freeman.
I also like deGrasse Tyson.
I am not a fan of Tyson so much...a lot of his opinions rub me the wrong way, but that is just personal preference. He is definitely a smart guy
He teaches a pretty good lecture series on The Great Courses about explaining mysteries of the universe.
One cool thing he points out about relativity is that time stands still for photons since they travel at light speed which (if you believe it) means that a photon traveling across say 30 million light years of space does so in an instant.
He also understands that we don't really know anything about the universe.
If you ever want to blow your mind, look up some of the experiments in Retrocausality. Scientists claim they have proven that a future event triggered the present event (past from the future event's perspective) on the quantum level
And replicated the event in the lab and published complete with peer review
Not only does that photon not experience any passage of time -- space (space-time, ya know.) contraction occurs as well. So from the perspective of that photon it hasn't moved through space at all. It's merely emitted and absorbed instantaneously within a tiny portion of spacetime. Pretty cool stuff.
@Darth I think I heard about that! They had set up a transmitter and a receiver and thought they were close to the receiver receiving the transmission before it was sent.
Oh, I forgot about this since I have the whole server muted. So yes, relativity just says that objects moving through space can't go faster than light, space itself expanding isn't really covered by that, since it's not moving through anything. I haven't really studied GR so I don't know all about that though.
"Well, as I understand it, the modern view of light isn't so much that its a particle/wave as it is something that exists in spacetime itself."
Modern physics doesn't need to make a hard distinction between 'objects' and light, the same set of equations governs them. They both exist in spacetime, it's where everything exists, and they both have wave particle duality. Electrons have wave properties too, if you send them though a narrow opening, they behave in a way that a pure particle never could.
is there any way to get notifications from just one channel but not the others in a server?
I think you can mute channels.
