If you put electrical current through water will it prevent it from freezing? Speed the freezing process up?

Is there way to determine how fast program will execute task?

Posted: 20 Oct 2018 03:20 PM PDT

I know some programming languages are faster and some slower, can we predict how much time computer need in particular language?

What exactly does it mean for something to be not locally real?

Posted: 20 Oct 2018 05:10 PM PDT

I have a decent familiarity with QFT. I prefer the Debroglie-Bohm interpretation as it allows for excellent models to explain and remember how things behave. It's easy on the intuitions. I realize it violates Belle inequalities in that it requires the universe is not locally real. What exactly does that mean?

Why does the oxide layer on aluminum protect it from corrosion, but the oxide layer on iron does not?

Posted: 20 Oct 2018 11:16 AM PDT

I've seen a lot of rusted parts on cars, light poles, bolts and everything in between rust all the way through over the years, but aluminum, despite oxidizing also, seems to be immune to the same effects of an oxygen rich environment. Why?

What happens to the pieces of an atom after it is split?

Posted: 20 Oct 2018 06:10 PM PDT

I'm not very knowledgeable on the topic of physics or fission in general, but I was curious about what happens to the halves of the atom after it splits. Do they disappear?

How does removal of leaf fall affect trees in urban environments over a long term?

Posted: 20 Oct 2018 05:49 AM PDT

There are a staggering number of leaves on the ground at the moment, and most of those leaves seem to be removed and ferried off away out of our cities.

Even a gardener at home will largely remove the leaves, with some maybe composting.

Over a very long period of time, how does removing all these recyclable nutrients affect the trees left behind? To what degree are we interrupting the Nitrogen Cycle?

Can Saturns "Rings" be individually identified?

Posted: 20 Oct 2018 04:48 AM PDT

Looking at Saturn from a Lay-persons point of view, the rings orbiting the planet always appears to have clear, striated layers. Are these actually layers that can be individually identified and distinguished, or are they more of an ever changing flow of layers. An additional point, in the case that they are individually identifiable, do the layers have name in the way that most astronomical bodies have names?

Why only Anopheles transmit malaria?

Posted: 20 Oct 2018 10:28 AM PDT

Hello,

I'm medical school freshman and we had citology and parasitology cycle this month. We were talking a lot about Culex and Anopheles but lectors didin't emphasize on why only Anopheles transmit plasmodium malaria, vivax, ovale, etc., and Culex don't?

Are hydrogen bonded, halogen bonded, and Lewis acid-base complexes all due to electrostatic attractions?

Posted: 20 Oct 2018 08:02 AM PDT

Hello,

I'm trying to straighten out some definitions between hydrogen bonding, halogen bonding, and Lewis acid-base complexes. To me, these three association interactions are all at a high level all driven by electrostatic forces (partial positive attracted to partial negative). I have put the following together as part of something I'm writing and want to run it by the r/askscience community (cross posted to r/chemistry as well). If there is something more to these three interactions than the "partial positive / partial negative", then I'd appreciate any suggestions (or recommendations in the literature) as to how to better describe each interaction and the differences.

Association interactions strongly impact phase behavior and thermodynamic properties. Association is the assembling of separate molecular entities into a complex where the bonding between the components is weaker than in a covalent bond. (IUPAC Compendium of Chemical Terminology, Gold Book, 2014). The most common association interactions are:
- Hydrogen bonding occurs when there is an attractive interaction between a hydrogen atom from a molecular fragment such as O–H or N–H and an electron rich region such as a lone pair or a π-bond. (Definition of the hydrogen bond (IUPAC Recommendations 2011), 2011)
- Halogen bonding occurs when there is attractive interaction between an electrophilic region associated with a covalently bonded halogen atom such as R-Cl, R-Br, or R-I and an electron rich region such as a lone pair or a π-bond region (Definition of the halogen bond (IUPAC Recommendations 2013), 2013).
- Lewis acid-base interactions occur where a Lewis acid (an electron pair acceptor) binds to a Lewis base (an electron pair donor) to form an electron donor-acceptor complex (IUPAC Compendium of Chemical Terminology, Gold Book, 2014).
The forces involved in the formation of hydrogen bond, halogen bond, and Lewis acid-base complexes are dominantly electrostatic. In all three cases, it can be said that an electron donor/electron acceptor relationship exists. If an interaction is primarily due to dispersion forces, then it would not be characterized as a hydrogen bond, halogen bond, or Lewis acid-base complex (Definition of the hydrogen bond (IUPAC Recommendations 2011), 2011).
Hydrogen bonding, halogen bonding, and Lewis acid-base interactions typically result in geometry distortion of bonded monomers relative to the un-bonded monomers. In all three cases, bonding typically results in penetration of the van der Waals volumes. For hydrogen bonded and halogen bonded complexes, the primary distortion is a lengthening of the R-H or R-X bond. For Lewis acid-base complexes, there is no typical distortion so bond length and bond angle changes will depend on the compounds involved. In all cases, the geometry distortions caused by complex formation can be observed with IR and Raman spectroscopy.

Thank you in advance for any insights or suggestions you can provide!!

John

Why are planetary rings not all around planets and instead just form a like like Saturn?

Posted: 20 Oct 2018 07:44 AM PDT

If gravity is omni-directional and debris floats around in space all the time why has none of the planets with rings have other things formed in different directions or even separate spaces on the planet never intersecting?
