How many of you have worked in quality industry? Either pharmaceutical/chemical, med devices, or software

Did you ever encounter an environment where quality associates were not encouraged to bring to light events and deviations? I know there are politics that evolve from quality statics at every major corporation, but some of them seem to be particularly "choosey."

Is it better to compromise your integrity and ignore details that may lead to a lack of compliance, or is it better to be 100% open and reveal any event that is observed?

Hoy, /sci/

This is stupid comic book and thought experiment shit, so feel free to ignore it. It's poorly worded word salad anyway, so only bother if you like theoretical nonsense.

Lets talk forces.

There's this guy. We'll call this random rube, "Ruben." Ruben has this amazing power. Ruben's power is not unlimited, so there's a finite expression of what he can and cannot do. Ruben has just enough power that he can suck kinetic energy out of objects with small mass and reduce and minimize impact and penetration by bullets before they penetrate his skin.

How? Comic book science. He can because he can. What are its limitations? Small caliber pistols and hand guns. Whether they're single slugs or shotgun blasts makes no difference so long as each individual object impacting with his field equals less than the kinetic energy he can cancel from each.

And yet, Ruben has a problem. Ruben's power is really good against objects that were given a single shocking amount of energy and don't sustain themselves, but he could not do more than subtract a little from the incoming forces of a rocket, which has its own propulsion, or a knife. Ruben could not really stop some dude with a spear intent on impaling him. Reduce the thrust that touches his aura by the amount of a handgun round? Sure.

Now we could easily calculate and give numbers to HOW MUCH kinetic energy Ruben could stop cold in newtons or joules, I'm sure. For extra credit, we could do that. But,

What specific imaginary comic book superpower would let someone do the same thing for stab attempts, arrows or things relying on their mass to stay in motion? There's a difference between a missile fired from a gun and, say, a safe falling from the sky to crush a dude.

Short of absolute control of gravity itself or magnetism, what sort of make-em-up superpower would let a guy like Ruben stop a dude with a steel mace from caving in his skull? That would use the abundance of mass against it?

>> No.9186050

You could make him like electricity and he zaps the abundance of mass away from his head as it touches his electric skin from his electric eel accident from his backstory also his favorite color is blue.

I know someone who dors it a lot and told me some things about it (I was sceptical obviously). He's Ukrainian and if he wins 50 bucks at some tournament it's quite significant for him.
It seems to boil down to game theory and psychology.
The way he described it knowing the probabilities is a given. What makes you win is paying attention, taking notes about how players play, generally taking many notes etc. Poker is a game of chance but humans arent random.
He also said there are the people who know poker and there are always the clueless ones who judt want to gamble. And the "sharks" can identify eachother and empty the other people's purses over the course of an evening.
So it is a lot about game theory and actually trying to win. Success is obviously not guaranteed.
Might be bullshit but I found it interesting.

Brainlet here, with a brainlet question:

If what I am seeing on my computer screen right now is basically ones and zeroes, why are the ones and zeroes from watching a 3D animated film less stress on hardware than playing a PC game on 4K? Isnt just one pixel of the screen I am looking at basically just gonna be a one or zero regardless of what I am doing?

On that note, can a computer create a random scenery that is "real?" Technically, when I take a photo and store it on my PC, it's not like it's making a mental note of how it looks like. It basically writes instructions on how to recreate the image when I copy it right? Does it then possess the ability and instructions on how to create a real photo that was never taken (or done in CAD)?

Well, for FPS games the like, it's quite a bit more complicated than that. The computer has to do raycasting to figure out what you can and can't see, then try to minimize the work to process the objects you can see, while prepping those you cannot that may enter the scene, then there's anti-aliasing, anisotropic filtering on angled surfaces, lighting, shadows, and post-processing, all that other crap. It's literally building a chunk of a universe as you go through, placing in every little prop you see as you are angled to it, and all the physics behind the motion of everything in the scene and just beyond. It's kind of amazing all the insane math that goes into it all - and indeed, things like PhysX have opened up whole new fields of math just to deal with those sorts of calculations that go into making these virtual worlds. (Although it's also a little embarrassing how much math has been dedicated to "breast physics".)

A movie, on the other hand, is just a series of images and sound. It's amazing how much work goes into those as well - between the props and special effects and all, millions of dollars worth, but by the time it gets on your device, all the work's all been done. In a game, the computer actually has to assemble the whole scene, figure out how everything in it is going to move, and "film" it as you play.

Plus, in a movie, when you blow something up, physics takes care of it for you. In a game, the computer actually has to work out those physics in an abbreviated enough fashion to both do it in real time and make it immersive. Games don't just show you a tweaked recording of reality from a single angle, as movies do, they actually have to build that reality and figure out how you're going to interact with it.

Thus, any computer can play back a movie, but not every computer can play Fallout 4 (or whatever the latest high-end game is, I'm a bit behind.)

By the way, the computer does not 'write instructions on how to recreate the image' unless it's a vector image. And even then, it's all ones and zeros on the drive. Technically, with an infinite amount of time, a computer could generate an image randomly that would resemble a real world location. It could also, technically, randomly create an image that would show how Lincoln really looked like (assuming the paintings don't portray him absolutely right) or what the core of the Sun may look like if imaged in some way. Check out the Library of Babel.

Everyone here is giving retarded answers so let me, a computer scientist (nowadays know as a faggot) explain...


Each pixel is not just a one or zero each pixel is a collection of atleast 32bits (ones or zeros) with 4 sections of 8 for describing the amount of red,green,blue and brightness. At least this is how it is on modern screens.

Movie's do take a shit ton of more hardware to create, in fact a single frame of a movie would take likely many months to render on a normal desktop computer if we were to truly re-render the movie from scratch everyone. There is a key difference between a movie and a video game too. A movie, once rendered to its final form (mp4, alv, etc), is just a snapshot of images from one perspective. A video game is more interactive and you can look around so the computer has to render everything from scratch. Not only that it has to do it 60 times every second to look smooth so we have to severely cut down on how good it looks.

Religion ad science is the same thing.

Sky-worship serves navigation in time and space, and has in its most dense form developed in nomadic steppes populations for whose lifestyles it's most important and manifested into it. As an example we can mention nomadic dwellings, which are directed along the cardinal lines, functioning as a clock and structured like a holy house sometimes referred as a ship.
The opening time dimension from tying life ensuring decisions onto reliably, frequently and constantly in intervals recurring celestial phenomena and the verbal sharing of the subsequent values, granted them the ability for transcendental thought to pull themselves up from the emotional trappings of the animal kingdom, allowing a sense for truthfulness, justice and beauty making planing possible, thus science and increased survival likelihood.

I will explain it further how science is the same thing and didn't pop out of nowhere but stands in an evolution... in relation to the given example.

Science isn't infallible but only speaks of likelihood and increases likelihood when forcing events. Principally there's really no difference if I call a certain star constellation the grey wolf or give it a Greek name when using it for navigation purposes. The guy increases the likelihood to get where he wants to, even if a more complex body of mythological aspects is attached to the term. Now you could say for example mythological symbols attached to the term and hence constellation unnecessary to getting the results shouldn't exist in the approach in order for it to claim scientific validity, but this would have to apply to current scientific approaches the same way which isn't true. In the scientific world never a most reduced architecture is being applied because we simply can't do it. Numbers could be written in a more reduced form, terms could ever be made more elegant... so where's the difference in a Shaman hitting a drum while increasing likelihood of survival of a diseased and a doctor wearing a white collar? You could say we're aware the white collar isn't needed, what about the things we don't know that aren't needed for the realization of increased likelihood? What about the approach we don't know of yet that works better?
It's rather magical thinking and dogmatism to draw clear cut lines and thinking the scientific method pops out of nowhere and its current state stands on nothing prior.

[Image not entirely related] Before I begin I apologise for the lack of grammar in this post as English isn't my first language. Anyways let's begin. I was attending a school football game and noticed a bright orb of light in the sky out of nowhere. To describe it I would say imagine the brightest star in the sky but brighter and larger in size. The brightness and size is so out of place it just don't seem like it belongs to a star. That's not the only thing bizarre about it, the strength of its light quickly fades out and then completely vanishes in about 20 seconds from when I first noticed it. But beyond that it seems to be stationary. I've googled a bit and the explanations just don't seems to match, satellites and aircrafts should appear to move across the sky. I was in a bit of shock at the moment and was unable to get a photo in time. I'm really baffled and confused by I just saw. What are you guys' thoughts on this?

How fast does light have to travel, in a circle (or straight line), for a photon to crash into itself from behind? Could this theoretical process continually multiply photons, creating an infinite light and energy stack?
Update me on the physics and mathematics of this.

Why would it ever do that?

The photon will be in a spot, then be in that same spot some time later. As the speed of the photons cycling increases the time separating the individual instances of the photon (or photons, distinct due to their locations in timespace) decreases. Eventually, the separation time approaches 0. Which is where multiplicatively singular photon overlapping could occur.

You should read about how lasers work.

Let me guess, social "sciences"?
