I have two questions for you, /sci/.

1) All science can do is falisfy claims, so does that mean that all scientific theories/laws are just the "least falsifiable" philosophies that we have.
Or to be more specific, the most logically appealing metaphysical beliefs that have yet to be falisified?

2) Was the development of QM really the death of determinism?
By this I mean, at the very small scale cause and effect are blurred, the larger we go and the more material we deal with the more structured thingsd look, or so I've been lead to believe. Is this just a result of statistical trends in the inherent chaos of sub atomic particles?

>Or to be more specific, the most logically appealing metaphysical beliefs that have yet to be falisified?
Well, not quite. "Yet to be falsified", yes. Even if all we know right now was 100% accurate, we would have no way of knowing for sure.
"Metaphysical", no. You can know if a scientific statement is wrong. The same is not true for metaphysical statements.

>2) Was the development of QM really the death of determinism?
I would hope not. I'm in CS, so I find an indeterminate universe to be aesthetically displeasing.
>Is this just a result of statistical trends in the inherent chaos of sub atomic particles?
I'm hoping in the best case it's just some hidden variable we are missing, or in the worst case the result of artifacts arising from measuring things very close to the granularity of the universe. In other words, accumulated error in multiplication of discrete values assumed to be continuous.

Why don't electrical engineers who work at a hardware level have to understand high level chemistry?

At what hardware level?

The smaller scale, the more important knowledge of how atoms interact becomes.

The common EE formulas are all abstracted from physics.

We assume that everything travels instantly, so we don't have to worry about writing a dissertation for every circuit we design. All the simple algebraic equations, like W = A x V, have extremely complex physics equivalents, but the simple algebraic shit works as well and we get the job done.

For complex circuits, most EE guys usually play with simulators that perfectly simulate the actual electrons, so we can find corner cases where the simple algebraic stuff doesn't work.

So, TL;DR: because it's too hard and it doesn't add anything.

>Abstract

Social comparisons are important because other people can serve as benchmarks to determine one's own capabilities and act as sources for inspiration. Despite this, people do not always fully utilize social comparison information. The present paper demonstrates that feelings of power may reduce use of social comparison information. In three experiments, participants were first induced to feel high or low in power, or were in a control condition. Then, they were exposed to either upward or downward comparison targets. In all three experiments, low power participants responded to targets with contrast or assimilation, whereas high power participants did not. This has important implications for our understanding of how people's positions in the social and organizational hierarchies affect their basic psychological functioning.
Highlights

► The experience of power makes individuals less open to social information, including social comparison information. ► The powerful do not respond with assimilation or contrast to social comparison information and therefore fail to integrate social comparison information into their self-concepts.

This is science.

How does an engineer look at the same information and see an opportunity to 'create' something out of it.

For example, could they manipulate the research such that they make somebody more powerful, or more socially conscious?

How does one become an able solo sailor?

I know the following steps. What is missing? Modern sail ship with proper equipment (comes standard????).

Learn navigation (how?),
learn hydrography (?),
get a map of shipping lanes (?),
get appropriate supplies to suit nutritional and water requirements for and beyond that period of time,
physical and mental training,
medicine, communication equipment.

Is there anything else? Anyone sail?
I'm studying geography so my academic grasp on, well, surface torpography is sound. However, the sea's are completely foreign to me. I am sure I could make the horizontal transition by discipline, and then the physical side will just take time.

It's really the resourcing which has me bothered.

What, if regulations is or is expected to come into place to ensure that when the technology emerges to amplify our brains with electrical signals and chemicals, that we don't fuck ourselves up?

Neuro-engineering is fast catching up with us!

I did an internship at a university lab last Summer.

Nothing really stands in the way other than nobody is volunteering and nobody wants to be the person to put the equipment on your head.

Can personal revelations or philosophical insight be drawn from mathematics?

I've done little math, but calculus gave me confidence in the reducability (as in reductionism: philosophy) of most scientific fields.

This is a science board so I would urge you not to confuse reductionism with redox: reduction/oxidation

Bile that isn't reabsorbed gives the colour.

Anonymous 13/04/19(Fri)01:39 No. 14931 ID: 0e78b5

You're both partly right. It's a combination of bile salts, iron (from dead and broken down red blood cells - mind there's no such thing as "dead haemoglobin"), plus the already slightly earthy colour of what's leftover once our bodies have extracted everything "useful" from ingested food.

Because it isn't any other color.

When the rules break down, when molecular assemblers are developed- what happens then? what will you do, when you can have everything. Is all that's left a meaningless playground? Will you do something scientific to overcome the terrible loneliness of everything being fake?

Strategy before implementation, fools.

2/ crazy but reversible body modifications and augmentations
3/ flying car
4/ moar sexbots
5/ brain-internet interface
6/ whatever the fuck you want for breakfast, lunch, dinner and snacks
7/ cat-loli sexbots that instantly turn into something far less embarrassing if someone else approaches in visual range
8/ your own backyard waterslide theme park
9/ bacon that doesn't kill you
10/ endless no-cal beer, plus instant beer antidote that sobers you up in minutes with no hangover

Depends what the "midnight" truly represents. If it's just one country attacking another with a nuclear device, then I think we're already counting down from 60 seconds.

It need not precipitate a global nuclear conflict, though. I don't think most of the other world leaders are that crazy or fixated on the east-west MAD-based ideological conflict any more. India/Pakistan or Israel/Iran may take it as an excuse to lob something of their own across the border at their old enemy if PRNK actually does Go Hot, but I'm not even sure they're unhinged enough for that.

I marched around the corner of a hangar and directly in front of one of those sunk in a story down once, and as we all felt a tingling sensation followed by some scattered stings we started to get a little warm... I have no idea what it was communicating with (maybe AWACS?) or on what frequencies or with what amplitudes, but we broke formation and ran like hell to get away from it. ...& then got chewed out by our CO for being highly visible retards (the worst kind of retards to be, as it turns out). Good times.
