@Freiheit - CA Your going to be competing against some of the biggest corporations in the world, do you plan on wildcating? I think that's going to be your only in, get in early like some of the smaller companies did in the bakkan. it doesn't help that there is record production of oil at the moment.

2018-03-07 18:59:31 UTC

I must clarify. I'm looking for an entry option. Where would someone with no experience begin to end at high pay?

2018-03-07 20:09:18 UTC

It's possible to walk onto a rig as a roughneck and elevate yourself to company man position if you are very competant, adverse to high stress, can pick up technical drilling intuition, and are ok with very little social life that comes with living in remote areas and a disproportionately male population. If you can handle all that there is good money to be made.

2018-03-07 20:27:23 UTC

@Brandon Ironside- ND Have you worked in the oil industry? I was under the impression the boom was dead

2018-03-07 20:32:29 UTC

@John O - only as an intern for a brief period. The boom is dead for now with the current oil prices. I choose to take my career into a different engineering direction after what little exposure I did have right out of college.

2018-03-07 20:33:14 UTC

there still is work though, just not boom levels

2018-03-07 20:33:47 UTC

Is it $120k a year like it was a decade ago?

2018-03-07 20:34:34 UTC

I'm not considering it, just wondering. I know a lot of guys who made ridiculous money back then

2018-03-07 20:41:59 UTC

newer engineers aren't making that anymore, senior engineers can make 200-300k still.

2018-03-07 20:43:35 UTC

my friends who did get oil engineering jobs are making 55 - 75k similar to other engineering fields just out of college

2018-03-07 20:47:36 UTC

I'm talking roughnecks

2018-03-07 21:01:06 UTC

41653

2018-03-07 21:32:38 UTC

Oh, yea close to above number now

2018-03-07 22:33:47 UTC

That sucks.

2018-03-14 04:31:16 UTC

Happy Pi Day!

2018-07-09 04:58:36 UTC

Any of you goys into data mining? I've been fiddling around with R a lot recently.

2018-07-09 18:20:48 UTC

@ThisIsChris Yeah I structure a lot of unstructured data on the web for economic system research mostly.

2018-07-09 18:21:37 UTC

Been getting into data science comprehensively lately, I feel like the field is about to blow up.

2018-07-10 12:13:39 UTC

@Attrition in the desert definitely! What data is it that you are making available and to who?

2018-07-10 16:27:33 UTC

@ThisIsChris Mostly data on commerce exchanges in SE asia. The place I'm working at now handles a lot of soft/hard currency transactions.

2018-09-18 01:54:12 UTC

That's neat. I wonder if it's simultaneously done in all areas of the animal.

2018-09-23 19:03:48 UTC

Hey guys, I'm Nick, and I'm a ChemE undergraduate from NY, excited to talk with all of you

2018-09-23 19:11:58 UTC

nic

2018-09-23 19:12:00 UTC

*nice

2018-09-24 01:38:13 UTC
2018-09-24 02:36:03 UTC

roll'd?

2018-09-24 03:21:31 UTC

@Nicholas1166 - NY sorry, role'd not roll'd. I gave you the @`AE` role (academic expert) so you will be alerted when people ping @`AE` with academic questions you may be able to help with.

2018-09-24 03:37:27 UTC

Ah, OK. Yeah, I'd be glad to lend a hand if I can, although I am just a junior right now

2018-09-24 04:23:03 UTC

I'm graduated from a university with a degree in math

2018-09-24 04:23:05 UTC

ask me math questions

2018-09-24 04:23:09 UTC

if you need halp

2018-09-24 04:31:53 UTC

I very well might, math is my weakest subject. Thank you for the offer.

2018-10-03 05:19:28 UTC

I didn't know this sever had a role thing. Can I get a role and be alerted?

2018-10-03 16:45:13 UTC
2018-10-22 06:55:35 UTC

@ThisIsChris hey do you have any good explanation on how to find isomorphisms between two polynomial factor groups?

2018-10-22 06:56:33 UTC

that is an isomorphism phi: F[x]/f1(x) -> F[x]/f2(x) where F[x] is the field of polynomials with coefficients in Z_q and f1(x) and f2(x) are irreducible polynomials in F[x]

2018-10-22 07:18:25 UTC

@YourFundamentalTheorum by F[x]/f1(x) do you mean a quotient group? If so, what is the group you are doing F[x] modulo with? f1 doesn't generate a group unless I am missing something

2018-10-22 07:18:42 UTC

@ThisIsChris quotient field

2018-10-22 07:19:06 UTC

and F[x] is a field of polynomials in x with coefficients in Z_q

2018-10-22 07:24:17 UTC

@YourFundamentalTheorum thanks. How about for an element of F[x]/f1 called G, take a representative g, phi(G) = the coset of g*f2/f1 . Need to prove that the coset is independent of the choice of representative g

2018-10-22 07:26:20 UTC

the last part is a given.

2018-10-22 07:26:24 UTC

On the right hand side I mean g times f2 divided by f1 in the normal sense for poly nomials

2018-10-22 07:26:44 UTC

F[x]/f1(x) is usually represented by all the polynomials """"less than""""" f1(x)

2018-10-22 07:26:51 UTC

a lesser degree than f1(x) that is

2018-10-22 07:27:59 UTC

Hm, what happens in the three cases where f2 is higher, equal, or lesser degree than f1?

2018-10-22 07:28:10 UTC

assume f1 and f2 are of the same degree

2018-10-22 07:28:16 UTC

otherwise you don't have the same cardinalities

2018-10-22 07:28:20 UTC

which means they can't be isomorphic

2018-10-22 07:28:42 UTC

the Galois fields can't be isomorphic that is

2018-10-22 07:29:51 UTC

Hm I think you can actually prove it if the degrees mismatch too. Since you assume the rep g has degree strictly less than f1, then g*f2/f1 should have degree strictly less than f2

2018-10-22 07:30:43 UTC

yes you can prove that

2018-10-22 07:30:46 UTC

it's quite easy actually

2018-10-22 07:31:14 UTC

the degrees part htat is

2018-10-22 07:31:28 UTC

we know the exact # of elements in F[x]/f1(x)

2018-10-22 07:31:35 UTC

it's going to be q^n

2018-10-22 07:31:41 UTC

i'm assuming q is prime btw

2018-10-22 07:32:18 UTC

Sure since it's irreducible. Otherwise, hm...

2018-10-22 07:32:58 UTC

If a polynomial has a non-prime degree, to guarantee reducibility you need to allow complex coefficients, right?

2018-10-22 07:33:48 UTC

i don't think it matters what the degree of the polynomial is

2018-10-22 07:33:58 UTC

like if it's prime or not

2018-10-22 07:34:06 UTC

i think what matters are the coefficients

2018-10-22 07:34:20 UTC

if you don't have prime coefficients, your polynomials stop being a field

2018-10-22 07:34:42 UTC

the reason why F[x] is a field is because Z_q is a field when q is prime

2018-10-22 07:34:48 UTC

if q is not prime, Z_q is not a field

2018-10-22 07:35:01 UTC

and therefore F[x] is not guaranteed to be a field

2018-10-22 07:35:24 UTC

Why is Z_q not a field when q is, say, 4?

2018-10-22 07:35:27 UTC

the very basic example is that say if you have Z_4, the polynomial "2" does not have a multiplicative inverse

2018-10-22 07:35:48 UTC

Ohh

2018-10-22 07:35:53 UTC

Neat

2018-10-22 07:35:54 UTC

Z_4 is not a field because 2 does not have a multiplicative inverse

2018-10-22 07:36:10 UTC

Yeah haha been a while

2018-10-22 07:36:12 UTC

and since Z_q is a subfield of F_q[x]

2018-10-22 07:36:26 UTC

yeah I've literally pullen out my abstract alg. book out today

2018-10-22 07:36:32 UTC

i need some cryptography knowledge from it

2018-10-22 07:36:43 UTC

i learned all of this again today ๐Ÿ˜›

2018-10-22 07:39:45 UTC

That's neat. I enjoyed abstract algebra but mostly only needed the linear algebra part since then (11 years ago). Rotation groups and some other stuff relevant to geometry, but not much more. Cryptography seems interesting, we did cover RSA at some point, I only remember the main idea, that factoring is hard ๐Ÿ˜

2018-10-22 07:41:23 UTC

@ThisIsChris wellyeah, some pajeets found a way to crack RSA with you guessed it, Galois fields

2018-10-22 07:42:06 UTC

Is that a recent thing?

2018-10-22 07:42:10 UTC

yeah

2018-10-22 07:42:12 UTC

like a year or so

2018-10-22 07:42:43 UTC

it's amazing how irrelevant Abstract Algebra used to be until computers, and now it's hella important

2018-10-22 07:42:47 UTC

Huh no kidding. Guess I better put 2FA on my bank accounts then

2018-10-22 07:45:28 UTC

yep

2018-10-22 07:45:36 UTC

idk about you, my dad make me take applied math

2018-10-22 07:45:49 UTC

it was "fun" i guess, but I really want to go back to college and get a pure math degree

2018-10-22 07:45:52 UTC

later

2018-10-22 07:45:53 UTC

๐Ÿ˜›

2018-10-22 07:46:04 UTC

pure math is so much more fun that learning about how to earn money at google

2018-10-22 07:47:09 UTC

"pure math is fun" I will never understand you types

2018-10-24 03:54:06 UTC

I'll stop there

2018-10-24 06:23:54 UTC

@YourFundamentalTheorum haha I like the sigma algebra one but don't get the epic one? It's a true statement if f is 1-1 and onto. Not sure what else.

2018-10-24 06:24:54 UTC

@ThisIsChris epic means an epimorphism

2018-10-24 06:25:01 UTC

which is literally defined by that equation
