Why do people with Alzheimer's not forget how to talk?

More specifically words, grammar etc. not how to physically talk

How do we know quarks are real?

Posted: 01 Jan 2017 11:00 PM PST

Specifically, can someone explain to me what deep inelastic scattering is and how this establishes the existence of quarks? I kind of want to know how they set up the experiment and what exactly were they measuring?

So how does the Fundamental Attribution Error, and the Social Information Processing Model coexist together in psychology?

Posted: 01 Jan 2017 07:43 PM PST

I am sure that whoever knows the answer to the question knows what these two entities are, but what I want to know is that how do they coexist. If the Social Information Processing Model relies on the behaviors of the individual based on past experiences, And the fundamental attribution error stipulates that the persons behavior can mostly be explained via external forces, and social psychologists stress (at least in the courses and material I have read) that people mostly behave certain ways based on external stimuli and not what happens inside of their head by their own. Isn't it possible for them to come to the decision to behave certain ways internally without the environmental forces social psychologists suggest are responsible for a person's behavior?

We generally count in base 10, computers use base 2 and hexadecimal, is there some orderly relationship among the various constants of physics that suggests nature has a preferred "base"?

Posted: 01 Jan 2017 06:17 PM PST

Part of the motivation for this is the question "Are we living in a simulation?" If so, we might expect some indication of the physics engine's architecture to show up in our physics.

If something is infinite, is it also necessarily exhaustive? Is the "infinite monkeys on typewriters will write Shakespeare" trope true?

Posted: 01 Jan 2017 01:54 PM PST

Not sure if I used the precise terminology ("exhaustive"), but the "an infinite number of monkeys typing on typewriters will eventually write Shakespeare" adage is a misrepresentation of infinity, correct? Like for instance, I could have an infinite set of numbers that never included the number 1234, right? It could just have 1233 and then expand into infinite numbers that start with 1233 without ever including 1234, and still meet the definition of "infinite", right?

I guess my question really is: does something have to include all possible outcomes to truly be "infinite"? Or can something have infinite outcomes but not all possible outcomes?

Leap seconds, why do they matter so much?

Posted: 01 Jan 2017 05:07 PM PST

If they need to perform a leap second something like every 30 years, why do we even need to do them? Surely the world won't be that much more different in environmental matters if we're a second out out. Like it'd take thousands of years to even notice a change in the time and the environmental time. We've only lived 200000 years as a species, a lot will change in that time.

Do mosquitoes share blood with each other? Also, do they "steal" blood from other mosquitoes, like from a dead one for example?

Why doesn't the water under the polar caps freeze, even though it is below the freezing point?

Posted: 02 Jan 2017 05:02 AM PST

There are of course more locations than the polar caps.I was wondering about this, since there are many bodies of water below freezing point that do not freeze.

Will the earth eventually (long-time eventually) cool to be solid right down to it's core?

Posted: 02 Jan 2017 04:46 AM PST

If the heat "Q" in a closed system is positive, does that automatically mean temperature will increase?

Posted: 02 Jan 2017 07:37 AM PST

Or is it possible for the work to be negative and have no change in internal energy, so no change in temperature?

If you look at any crude oil assay, the sulfur content increases as you go from heavier fractions in crude oil (as in from LPG to fuel oil). What causes this?

Posted: 01 Jan 2017 01:30 PM PST

http://corporate.exxonmobil.com/en/company/worldwide-operations/crude-oils/assays

I've been looking around and the sulfur content always increases as you go from light ends to vacuum residue. Is there any phenomenon that explains this? Does something make it easier for sulfur to accumulate in heavier molecules?

Is there any historical data that actually link a swarm of small earthquakes to a major quake? IE: is there anything that indicates that the current swarm in Bradley, California could possibly be anything other than the typical swarm that never precedes a major earthquake?

Posted: 02 Jan 2017 06:55 AM PST

One hears of quake swarms semi-regularly, today's CA/MX border cluster of 250 quakes under and around Brawley, California.

These swarms happen all the time, but the vast majority of them never precede a major quake so they seem to be a particularly poor indicator of imminent disaster.

Looking at, say, the 1,000 strongest quakes in recorded history. How many - if any - were preceded (within 72 hours) of a similar swam?

How do orbiting telescopes track stars?

Posted: 02 Jan 2017 06:41 AM PST

I would imagine small jets to orient them but wouldn't that result in a very jerky movement?

If breaking a chemical bond requires energy why is enthalpy of atomization a positive value?

Posted: 02 Jan 2017 06:37 AM PST

I understand that when a bond forms energy is released so wouldn't breaking one consume energy from its environment? How can splitting them also give energy? Besides, if we can have it both ways we would be able to get it for free!!(yay?)

Is there a theoretical maximum number of stars that can stably co-exist in a single system?

Posted: 02 Jan 2017 02:42 AM PST

Over on /r/elitedangerous, someone discovered this star system: https://i.redd.it/y9t5kcs7577y.jpg - 15 main sequence stars, 5 brown dwarfs, and 3 black holes. Elite Dangerous uses procedural generation to fill in the star systems that we don't know about; I just wondered how likely systems chock full of stars like this would be?

If I touch a metal and wood both in the same temperature, like 15° C, I "feel" the metal is colder than the wood. Does that mean I can touch very hot stuff like 150° C without feeling it's hot? Also, what physical properties affect the feeling of hotness and coldness of the materials?

Can you tell someone's native language by looking at a scan of their brain? What about bilingual, trilingual, ect?

With reports of the super volcano in Italy had begun to awake and "stir" what effects would an eruption of that size have on not only the immediate area, but also the world as a whole?

How are memories formed and stored in the human brain? How does information go from "pattern of electrochemical activity" to "hard" storage?

Posted: 02 Jan 2017 05:35 AM PST

I've heard that memories are solidified during sleep: does this mean that information is sitting in "RAM", so to speak, until then? And is this why we get tired?

Are there specific structures that contain memories, or are they distributed throughout our neural net? A combination? Can we detect changes as memories are formed using an MRI or other instruments?

How is memory assigned in hardware?

Posted: 01 Jan 2017 02:27 PM PST

When I write a line of code in C like

int x = 5;

How is that value physically written into the computers memory?

Why don't humans have a mating season?

Posted: 01 Jan 2017 09:48 AM PST

Most mammals have a mating season. Why not humans (not that i'm complaining) ;) ? Was there any such thing at any point in human history.

Are there any materials that change state from a liquid to solid under heat?

[Game Theory/Economics] How do open markets behave when no information is shared?

Posted: 01 Jan 2017 10:02 AM PST

In markets where information and date are highly sought after, especially to avoid information asymmetry and the free-riding issue, how would a very large number of agents act when no information about quality, details, origin of a product and agents is shared? Thanks!

Can someone explain this "fast formed fossils" experiment to me?

Posted: 01 Jan 2017 10:00 PM PST

When I was in high school, we were taught everything through a young earth creationism lens, and one day they brought in some guy who supposedly demonstrated that fossils don't prove the earth is older than 6000 years because you can make a fossil overnight. He showed us what he claimed to be a fossilized teddy bear he had made. I don't know enough about fossilization because this was my science education, but I have to assume if this was really the smoking gun argument, we would have to rethink everything.

The guy who showed us this was a big Ken Ham fan, and Ken Ham's site is the only thing that comes up when you Google around for this stuff, and talks about this exact experiement (article here). I'm sure it's bullshit, but can anyone explain to me what's wrong here?
