If you where to be tested with a lie detector, would you be able to cheat it? I was thinking, if they asked you a question which the honest answer to was no, could you ask yourself a question in the head in which the honest answer is yes, then use that as the answer and pass the question they asked without getting caught? as you are technically skipping their question and answering for another.

Lie Detectors aren't detecting truth/lie, they're detective if you have a spike in stress which is associated with lying. My father had a friend who couldn't get a job because they asked him if he did drugs. He didn't do drugs but his brother use to be an addict. He kicked his brother out of the house because he wouldn't stop storing weed everywhere and his brother killed himself that night. So when they asked him on the lie detector if he did drugs, he said no but his stress levels spiked because of the memories so he couldn't get the job.

Another friend was asked if he was a Russian Spy during the cold-war era for a job, and he was so offended by the question that the lie detector thought he was lying.

Have you ever felt that you could comprehend the world better after learning, for example, thermodynamics, even in totally unrelated topics such as philosophy?

Have you ever noticed that patterns “of factual relationships” and the structures “of ideas/thought” seem to repeat themselves, at some fundamental level in science, philosophy, and even literature?

Have you encountered books or lectures that were substantial enough to affect your life by making “reality” more accessible, especially after thinking and applying its ideas? I’m talking about such an effect that it inserts “context” and “purpose” into your worldview, grounding yourself where one was formerly lost and inspiring yourself to investigate further with this new-found understanding.

-- --

I think there’s something underlying, unifying factor in all of these observations, and I think it would be an interesting project for /lit/ to tackle, for the sake of developing our own wisdom.

-- --

I hold the belief that there are certain fundamental “relationships”, for the lack of a better word, that unites concepts within disciplines and across all disciplines. This refers to both 1) the self-evident facts and the raison d’etre that grounds a discipline; and 2) the understanding that certain fundamental patterns—of logic, syntax, information, philosophy, mathematics, or whatever you want to call it—repeat themselves across all disciplines.

All investigations are a form of problem-solving, which means that unrelated disciplines such as psychology and literary theory share the same endgame of wresting some understanding from the world, with perhaps the possibility of some analogous relationships, though the building blocks may be of different qualities. I think that it’s plausible that there exists some basic, atomistic “units of understanding”, though I find it hard to define beyond intuitions.

If you are left believing you have more answers than questions after learning then you are deep within Dunning–Kruger.

Agreed. But I never stated that you'd suddenly have all the answers.

>I’m talking about such an effect that it inserts “context” and “purpose” into your worldview, grounding yourself where one was formerly lost and inspiring yourself to investigate further with this new-found understanding.

You start with few questions, because you don't know when to begin. Then you're provided a solid foundation that allows you to see the big picture, and then you're flooded with questions that need solving.

>>8810863

If your first thought wasn't pic related, then perhaps you're not capable of abstract thought. Have you never had a moment like "analytic philosophy made clear scientific writing easier" or "learning economics provided a new lens for understanding history"?

Consumer electronics produce no ionising radiation at all. Visible light has higher energy per photon than what these things put out.
People hear "radiation" and lose their shit, but these wavelengths (i.e. radio and microwaves) are harmless at reasonable irradiance

How does time dilation work
20 posts and 3 images submitted.
>>
It directly follows from the fact that the speed of light is measured the same in all inertial reference frames, which requires that observers in frames going at different speeds must measure time intervals as different to compensate for this.

Everything follows mathematically from the speed of light being invariant.

But your cells will age exactly the same way. So how is it possible that when you return from your, say, .5c 10yr trip, your cells have aged less than the cells of those who have stayed on earth?
>>
>>8810446
Sorry I thought you just meant time dilation in general. The twin paradox is a bit complicated for me, even in my last year of my undergraduate, I've always been terrible at relativity lol

I think that because the proper time along the geodesic is maximised for the twin on Earth who is inertial relative to the travelling twin, although I'm not too sure

>Most fields in biology are flooded and because of it you aren't likely to instantly get a job
>Population genetics is a field that is hiring anyone they can, it pays well and the subject is interesting and varied
>Almost no one wants to get a degree in it
Someone explain. Is it the fact that you have to take a few statistics classes? Is the bits of genetic classes too hard? Is it that it's an unknown field? Why wouldn't you want a degree in something that will give you a guaranteed job doing what you want with good pay?

Why are there so many pseudo-intellectual teenagers who think they're fucking geniuses because they read a little Nietzsche when in truth they probably couldn't even do something as simple as completing the square of a quadratic equation.

I'm not saying you're only intelligent if you mainly study math. But all intelligent people, regardless of the subject they study, should be good at math. Besides, completing the square is algebra II shit.

Why is the derivative not defined like this? It's clearly more accurate this way as h goes to zero faster. In fact we can take it to the power 3 or 4.
51 posts and 12 images submitted.
>>
>>8809085
why not just take

[eqn]\lim_{n\to\infty}\lim_{h\to0}\frac{f(x+h^n)-f(x)}{h^n}[/eqn]

for maximum accuracy
>>
you want the definition to be as simple as possible. and that denotes the derivative, not some process to find it. I think you are mixing exact mathematical declaration with numeric computation process.
>>
>>8809102
Exactly. This is the most natural way to look at it. Can this be consistently implemented in modern math? If not, the theory we have right now clearly is flawed.
