Does Carbon-14 dating work for wooden objects submerged underwater? If so, how does it differ from testing things which are on land?

When seismic waves encounter a mountain range, do the waves continue along at sea level or do they travel up and down the mountain sticking towards the surface?

What is the radius of the targeting footprint of an average MIRV-capable nuclear ICBM?

Posted: 06 Jul 2019 03:51 PM PDT

I've been unable to find this information anywhere. I'm led to believe it's generally kept a secret. But I can't even find a guesstimate.

What I'm referring to is the geographical land area that the warheads from a single MIRV delivery vehicle can be targeted over once it achieves the peak of its trajectory. For example could a single missile direct warheads to both New York and Chicago, or is the footprint smaller?

How do nerves work exactly?

Posted: 06 Jul 2019 10:14 AM PDT

Since you never really touch anything and the sensation of touching is the force of your atoms pushing away from each other, what do the nerves "feel" or how do they work? Also how do we hold up objects if we never touch?

Are victims of sexual abuse more likely to identify as something other than heterosexual and if so, why?

Posted: 06 Jul 2019 06:55 AM PDT

I work at a residential boys home with DCFS (Division of Child and Family Services). Our boys are victims of sexual abuse and have been removed from their homes for this and often other reasons. This is probably the only trait they all share.

National stats say that about 5% of Americans identify as something other than heterosexual.

However, out of our 16 boys, 10 of them openly identify as something other than heterosexual. Everything from Bisexual to transsexual. And that number is fairly low. It's common for us to only have one or two who identify as, and behave as, heterosexual.

If their sexual identity was not at all tied to their past as victims of sexual trauma (again, the only trait I can think of that they all share), then you would expect their LGBT numbers to roughly match the national average because as far as that demographic is concerned, we'd be essentially taking a random sample from among them, but apparently we are not. The numbers hover more around 60-100% LGBT.

I realize that even if we take every kid Ive ever worked with over my years in this job, it would still be a small sample size, but its enough of a pattern that it makes me wonder if theres any sort of connection.

I remember a few years ago, there was a TIL that said that child victims of sexual abuse are 75% more likely to identify as something other than heterosexual, and theyre *usually* good about their sources there, but I cant find it now. Google only shows this article which is not exactly a reputable source and says that pedophiles target feminine children, but for some reason that seems unconvincing.

Can anyone shed some light on why victims of sexual abuse seem to be much more likely to identify as something other than heterosexual?

Does a computer do mistakes sometimes within the billions of operations they do every second?

Posted: 06 Jul 2019 03:43 AM PDT

It sounds insane to me such intricate circuits flawlessly execute all of these operations all the time correctly, but at the same time it also sounds strange to me the computer could function properly with mistakes within operations being a common thing. I don't think Fermi's approximation could work with computers, but I might be wrong.

PS. I don't want a yes or no answer, but an elaboration, please.

Do HIV attack b-cells and natural killer cells?

Posted: 06 Jul 2019 09:09 AM PDT

Does HIV attack b cells? And does B cells have TLRs? If so what type of TLR do they have?

The same question goes with Natural Killer cells, Does HIV attack natural killer cells? And do they have TLRs? If so what type of TLR do they have?

Is there a minimum time we need to touch something in order for our brain to process it and make us feel it?

Posted: 06 Jul 2019 02:00 AM PDT

Like if we were to touch something or someone for only one femtosecond, would our brain even realize it? Is there a minimum time we need to touch something in order to feel it at all?

Does it make a difference whether this is something nice we feel (like the hand of a loved person) or something 'bad' like a pointy needle?

Do nuclear fuel rods decay uniformly?

Posted: 06 Jul 2019 02:10 AM PDT

As I understand the whole point of a control rod is to limit the reaction by shielding some parts of the fuel more than others... wouldn't that cause the fuel to be spent unevenly? Do nuclear reactor operators rotate which control rods are utilized to even out the depletion? Or are the control rods pulled out progressively farther over time as the fuel decays?

How is dietary citric acid metabolised in the human body?

Posted: 06 Jul 2019 02:01 AM PDT

Does it have anything to do with the citric acid cycle, or is it processed some other way?

By glancing over the citric acid cycle, it almost looks like citric acid could be metabolised as a sugar, is that even possible?
