Wolframalpha has an App I believe. It's one of the most powerful computational engines I know of, try it out on their website.

Wikipedia actually has very detailed information on many substances including properties, structure, and applications. You would just need an internet connection to look up info.

what we see as light is just one narrow band of a very large spectrum of electromagnetic radiation. but im a bit confused by the "electromagnetic" part. does this mean that any form of magnetism is in fact, light? would the ends of a bar magnet light up if we could see into that spectrum?

Divisions of color and the spectrum band is pretty fucking amazing stuff. There was a great issue of scientific ameritard that illustrated how the whole shitting mess with rods & cones in the eye. In the mean time, have a fun listen through this: http://www.radiolab.org/2012/may/21/

I don't know of any critters that "see" the magnetic field, though, many species of insects use it for navigation, so maybe... but it's possible. Every few months animal researchers discover some new species that has really sophisticated sensory inputs. Like recently, the bumblebee, which, aside from seeing electromagnetic radiation, also "sees" with added electric field data. Like this http://www.nature.com/news/bumblebees-sense-electric-fields-in-flowers-1.12480

Off topic, but similar to what you're talking about, I think not too long ago it was discovered that dung beetles navigate by the light of the milky-way at night. Crazy.

Electromagnetic means what it says. To get the electric part, you need to move or spin the bar magnet. If you could spin it fast enough, it would light up. But it would have to be really really small so it could spin that fast.

Yes, I can tell you what they are and what they mean and infer exactly.
I have good reason not to yet.
Can you tell me what country they are from, and what industry's data they relate to.

And yes, you did come to the right board.

Also, there should be a fuck load more measurements than you have here, particularly if they were taken by a GIS system

Obviously the largest number is 112, the first number is two digits, maximum value 54, and the second number is three digits. The first number is followed by a N or S and the second number is followed by an E or W.

Clearly this is a secret message of some kind that you are trying to communicate to your spy masters in an unfriendly country. Security should be with you shortly.

When one plate goes under another plate, does it ever come out? If it doesn't, would all the plates eventually become a single mass?

>When one plate goes under another plate, does it ever come out?
Not as such. When this happens, it melts into the mantle. Lava pours out at some other fault where the plates are pushing each other apart and once it cools it becomes a new part of the plate.

If you drop those two plates, they can indeed break and become a single mess.

Would it be possible for a man with an extremely deep voice to imbibe Sulfur Hexaflouride and have their voice pass out of the audible range of humans? Would it still be in the range of a dog's hearing, if so? How cool would it be to see a man moving his mouth, but appearing to so nothing, but a dog doing tricks to commands nobody could hear?

I'd first check the M.S.D.S. for Sulfur Hexaflouride if I was you.
(or maybe Hexafluoride, if that is what you mean)

What is the structure of memories on a neuroscience level? How about the metastructure that organises inter-relation between these sub structures? Can we see a different between insights, to raw footage, so something else?

No, you will need to learn to add and subtract.

What is the fastest way to learn chemistry and get an intuitive grasp on the subject _matter_? What book, video or exercises should I do?

I'm applying for chemical engineering this fall and I want to be at the top of my game. Help me out /sci/.

In return, have the best picture of Carl Sagan I currently have on my harddrive.

The most accessible introductory chemistry book I've found so far is Chemistry Made Simple by John T. Moore (revised edition, copyright 2004 or later). It's light on mathematics and extensive on concept.

Is this what you're looking for, or perhaps were you looking for something heavier on the maths involved?

Fastest way to learn chemistry? Undertake a course of study in the field.
