Hey, if you copy and paste equations into the Windows calculator accessory, it will solve them for you. The only symbol that it does not recognize is ^. Do you know of another way to enter that symbol on the Windows calculator? I am trying to copy and paste an amortization formula, but it won't work because it uses the ^ symbol.

ThisIsChris 2017-12-04 04:15:47

@Rick That's tough, it may not take it. Have you tried Wolfram Alpha? https://www.wolframalpha.com/

ThisIsChris 2017-12-05 17:40:25

@Deleted User It's from "Pattern Recognition and Machine Learning" by Timothy Bishop. I was just glancing through it while waiting through the train. For my job (datascientist) I like to have at least a high level acquaintance with these things in case they come up.

I want to start picking up some IT certs to make a career change. Any advice on where to start learning what I need for CompTIA A+? Any good free resources, or should I just pick up a book from Amazon?

FivePointPalm 2017-12-10 18:12:07

I would say just get started. Setup an old PC as a Windows Domain Controller or something like that. I don't know much about IT or Windows but I got into web development by just doing it, picking up languages and technologies at home as a hobby and then at work as needed.

Deleted User 2017-12-17 16:30:21

If gravity affects time as well as space, and the Big Bang is the mother of all gravitational events, is it true that there may be some places in the universe that the Big Bang, which to us happened 13 billions years ago, actually just happened an instant ago?

Deleted User 2017-12-17 17:21:16
Joe-MN 2017-12-17 18:00:19

Don't know a lot about general relativity to be honest. That's a good question. I don't think the big bang itself would be a factor, but if something has been moving relative to us for a long time and then slowed down to catch up with us, it would be younger. Likewise if an object spent a lot of time in a high gravity environment, it would be younger. Also since it takes a finite amount of time for light to travel, when we look at galaxies very far away, we're looking back in time.

Darth 2017-12-17 18:23:25

The weird thing is that the galaxy can expand faster than the SOL which is hard to wrap my head around but definitely goes to the temperaneousness of the Big Bang for certain places in the universe.

Deleted User 2017-12-17 18:24:22

I had not heard that one.

Darth 2017-12-17 18:28:03

I am a layman, so I will defer to the experts. But my understanding is that only physical objects are bound by relativity and SOL rules. The universe itself is not physical so the SOL rules don't apply and I have read in multiple places that the universe does/did expand faster. How that jives with time and space is something cool to think about.

Deleted User 2017-12-17 18:50:02

Sure is!

Deleted User 2017-12-17 18:50:45

The concept makes sense - spacetime itself not having mass and therefore not being bound by the same rules as things that have mass

Deleted User 2017-12-17 18:54:30

Light has no mass though. A lot of theoretical physics seems to be a group of lazy (((people))) that made up ideas to make their equations work

Deleted User 2017-12-17 19:01:55

Well, as I understand it, the modern view of light isn't so much that its a particle/wave as it is something that exists in spacetime itself. Kind of like the color of my shower curtain. I shake the shower curtain and the color ripples.

Deleted User 2017-12-17 19:02:18

But there's no, err, shooting, of a separate particle, like a canon.

Darth 2017-12-17 19:09:51

If you want to watch a show that will blow your minds, check out Through The Wormhole With Morgan Freeman (I know, but he is just the narrator). The show is a science doc that focuses on these questions and interviews top scientists from around the world.

Darth 2017-12-17 19:12:03

It primarily focuses on the convergence of physics and philosophy.

I also like deGrasse Tyson.

I am not a fan of Tyson so much...a lot of his opinions rub me the wrong way, but that is just personal preference. He is definitely a smart guy

Deleted User 2017-12-17 19:14:06

He teaches a pretty good lecture series on The Great Courses about explaining mysteries of the universe.

Deleted User 2017-12-17 19:15:39

One cool thing he points out about relativity is that time stands still for photons since they travel at light speed which (if you believe it) means that a photon traveling across say 30 million light years of space does so in an instant.

Deleted User 2017-12-17 19:16:04

He also understands that we don't really know anything about the universe.

Darth 2017-12-17 19:19:33

If you ever want to blow your mind, look up some of the experiments in Retrocausality. Scientists claim they have proven that a future event triggered the present event (past from the future event's perspective) on the quantum level

Darth 2017-12-17 19:21:12

And replicated the event in the lab and published complete with peer review

Dan iiii 2017-12-17 19:27:24

Not only does that photon not experience any passage of time -- space (space-time, ya know.) contraction occurs as well. So from the perspective of that photon it hasn't moved through space at all. It's merely emitted and absorbed instantaneously within a tiny portion of spacetime. Pretty cool stuff.

Deleted User 2017-12-17 19:33:58

@Darth I think I heard about that! They had set up a transmitter and a receiver and thought they were close to the receiver receiving the transmission before it was sent.

Joe-MN 2017-12-19 15:49:46

Oh, I forgot about this since I have the whole server muted. So yes, relativity just says that objects moving through space can't go faster than light, space itself expanding isn't really covered by that, since it's not moving through anything. I haven't really studied GR so I don't know all about that though.

Joe-MN 2017-12-19 15:57:11

"Well, as I understand it, the modern view of light isn't so much that its a particle/wave as it is something that exists in spacetime itself."
Modern physics doesn't need to make a hard distinction between 'objects' and light, the same set of equations governs them. They both exist in spacetime, it's where everything exists, and they both have wave particle duality. Electrons have wave properties too, if you send them though a narrow opening, they behave in a way that a pure particle never could.

@Why Tea I do some at work and did some for my degree

Do you ? @Why Tea

Why Tea 2017-12-25 00:11:52

Cool. I've been reading some on coding it. My employer (big big company) is a huge player in it, but I'm not involved in it at all at work.

Why Tea 2017-12-25 00:12:44

Is this a good place to start (sure looks like it) and what other resources do you think are worth looking at?

Why Tea 2017-12-25 00:14:01

@Deleted User Yes, one way / model of dealing with AI.

ThisIsChris 2017-12-25 00:28:44

@Why Tea what resource to use and what to focus on depends a lot on what you're actually working on.

Are you doing some sort of image or signal processing? If so then yes Neural Networks sounds good and that site is a good start.

But Neural Networks aren't useful for every problem (though some academics are trying to push the idea that they are) so step one I would ask are you absolutely sure they are necessary for your work.

You can tell what machine learning things to focus on by laying out what type of inputs and outputs you are doing. The dimensions your data can fit are usually sequential vs non-sequential (i.e. a sentence is a sequence of words, an image is just a single vector of numbers) and categorical/symbolic vs cardinal vs ordinal.

Why Tea 2017-12-25 00:31:22

Right, right. Thanks. But I'm not working on anything *specific* yet, as I'm trying to learn.

Why Tea 2017-12-25 00:31:47

Of course one of the best ways to learn is to pick a thing you'd like to do, and try to solve the problem, but I'm not there yet.

Why Tea 2017-12-25 00:42:02

Excellent, thanks!

I love the MIT courses that are available.

ThisIsChris 2017-12-25 00:42:24

MIT open courseware on Artificial Intelligence

ThisIsChris 2017-12-25 00:44:10

You're welcome, yeah they are great

Tanner - SC 2017-12-25 01:12:34

I’ve also heard good things about the Coursera online courses for this.

Tanner - SC 2017-12-25 01:13:29

I took a Coursera course in Data Analytics learning R and they did a better job than Texas A&M’s graduate class on the same topic (I took both).

ThisIsChris 2017-12-25 01:17:31

Yeah Coursera's first course was a pretty good Machine Learning Course by Andrew Ng, but last year they changed the format of the Coursera website SO MUCH that I now find it virtually unusable. That's partly by design, they give very little away for free anymore and they tightly restrict when materials are available.

Tanner - SC 2017-12-26 03:03:23

So just pay for it.

ThisIsChris 2017-12-26 03:45:00

That probably works for some people, but ever since after I finished school I usually study a subject in spurts in a way that doesn't fit well with Coursera's pricing model. I say this as someone who has paid for their courses and generally didn't get my money's worth before they expired.

ThisIsChris 2017-12-26 03:46:10

The best experience I had with a paid Coursera course was when I was doing a programming course with other people. I feel like that model works best for Coursera because that's closest to the classroom model they are going for

ThisIsChris 2017-12-26 03:48:20

When I study on my own though, I like to dive deep into something in a few goes when all of a sudden a few spare hours open up. Coursera is not conducive to this though. Courses start periodically so if it doesn't happen to be the first week of their course then you are SOL. And then the longer courses they have roll out the course material one week at a time, preventing a dive in.

ThisIsChris 2017-12-26 03:49:10

That's why I like to just have all the course materials available at once, all the time. I don't think Coursera has that model for any of the courses I was interested in though.

It's a lot of hype concealing a clever compilation of basic techniques but a very powerful concept once understood.

Perihelion - CA 2017-12-29 00:05:22

It's most useful applications involve large datasets. Currently there are innumerable opportunities for application. The limiting factor is usually expertise and leadership buy in.

Perihelion - CA 2017-12-29 00:06:20

Even still one of the most widely applied machine learning techniques is linear regression.

Perihelion - CA 2017-12-29 00:07:04

This fact reveals the simplicity at the core of the concept.

Perihelion - CA 2017-12-29 00:08:18

Its a beautiful simplicity though and there is a growing library of well documented algorithms for various applications. Even still > 80% of the work is just wrangling the data and pre processing.

Perihelion - CA 2017-12-29 00:12:07

If you want to learn check out kaggle.com look at winning solutions for problems that interest you.

Perihelion - CA 2017-12-29 00:12:47

For coding I recommend "anacondas" python distribution.

Perihelion - CA 2017-12-29 00:13:15

Comes with lots of machine learning and data wrangling libraries pre installed.

Perihelion - CA 2017-12-29 00:14:30

Getting involved in a datakind.org project is another good way to learn.

Anybody do tutoring stem in college? how practical idea to make money in college, it sounds like a good idea eventually I'm studying electrical engineering and so far in calculus one.

ThisIsChris 2017-12-31 13:59:14

@Tyler Baker I made some decent side money while tutoring in college, I was charging faily cheap and networked quite a bit

ThisIsChris 2017-12-31 14:00:04

It helped that I worked in the school's tutoring center, students liked my tutoring and asked for private tutoring outside the scheduled hours I worked for the school

Tyler Baker 2017-12-31 14:04:56

sounds good, I was thinking about working in the tutoring center and then eventually doing private tutoring wich im sure is more of a responsibility.

ThisIsChris 2017-12-31 14:07:51

@Tyler Baker yeah there's a great economy of scale in doing it this way, in the sense that at the tutoring center you figure out what it is the students are learning at that time, and it gives you a place to practice that topic and make mistakes if working through it the first time in a while, and then you're prepared for private tutoring

ThisIsChris 2017-12-31 14:09:18

private tutoring later that week I mean

ThisIsChris 2017-12-31 14:09:39

and then during finals week I wound up working 8-12 hour days tutoring

ThisIsChris 2017-12-31 14:09:50

at 20 bucks an hour off the books it was pretty nice

Tyler Baker 2017-12-31 14:10:34

yeah exactly

ThisIsChris 2017-12-31 14:11:39

What I did during the school year was grading + tutoring for the school + private tutoring

ThisIsChris 2017-12-31 14:12:13

it works out alright when you add it all up, and it's all related so you aren't switching modes too much

Why Tea 2018-01-05 01:53:55

@JC17-OR I primarily want to be able to identify jews by looking at them, I'm secondarily curious in knowing the features of various other subpopulations especially european ones

JC17-OR 2018-01-12 04:12:56

I can't think of any textbook which has that kind of info. The best advice would be to study the faces of known Jews. The trick is in the proportions of facial dimensions, though some Jews are hard to spot due to mixing.

ThisIsChris 2018-01-12 04:14:32

Yep, one of the things I looked into recently (mentioned on the daily shoah) is what's called "the semitic smile". It's a way the lips curl on semitic people that gives them a slight smiling look, that euros don't have. It's more distinctive among semites than the famous jew nose. I'd like to know all these features of identifying so not only relying on one (like the nose) but on a few different ones in trying to determine if someone is a jew by eye. In my day-to-day experience I think I meet more Jews than normal whites, and often you can just tell but sometimes it's ambiguous and it would be helpful to know distinguishing features among jews and euros to understand better.

JC17-OR 2018-01-12 04:18:57

Interesting, I've not heard of the smile. I mostly identify Jews by the traces of admixture you can see in facial proportions. Natural eye I guess.

ThisIsChris 2018-01-12 04:19:51

@JC17-OR is there a name for that? In fact I think I heard someone mention something about almond eyes

JC17-OR 2018-01-12 05:30:28

Depends on the field. Analytical psychology still has p-values and statistical analysis, but cultural, social and abnormal have reduced their empiricism drastically.

JC17-OR 2018-01-12 05:30:56

When I was studying criminology, we didn't review a single study with statistical analysis.

@ThisIsChris I would recommend reading "racial biology of Jews". It's older, but may help you in your endeavors to understand the biology and ancestry of the Jews.

ThisIsChris 2018-01-16 18:32:12

@Cait_Bradshaw - MA what's that?

JC17-OR 2018-01-17 03:07:58

It was a Space X satellite that was secretly launched supposedly.

StrawberryArmada 2018-01-17 03:19:58

It was a US satellite designed by Northrop Grumman or something

StrawberryArmada 2018-01-17 03:20:06

And launched by spacex

StrawberryArmada 2018-01-17 03:20:20

Supposedly it "failed"

StrawberryArmada 2018-01-17 03:20:41

A problem with second stage separation apparently

StrawberryArmada 2018-01-17 03:21:02

But SpaceX claims the second stage separated correctly

StrawberryArmada 2018-01-17 03:21:25

The Gov refuses comment because the nature of the satellite is classified

StrawberryArmada 2018-01-17 03:21:48

The satellite is however essentially "registered"

StrawberryArmada 2018-01-17 03:22:06

Which only happens if it completes an orbit or something

ThisIsChris 2018-01-17 04:56:55

@StrawberryArmada that's interesting!! Do you think something spoopy is going on?

Der Seeteufel - SD 2018-01-17 06:09:53

We launch secret stuff all the time. I'm kinda surprised they used spaceX but if the launch was time sensitive maybe NASA didn't have a vehicle ready.

StrawberryArmada 2018-01-17 14:46:28

NASA doesn't have its own launch capabilities anymore I believe

StrawberryArmada 2018-01-17 14:46:53

They are wholly reliant on SpaceX, Space Launch Alliance, and worse: russia

StrawberryArmada 2018-01-17 14:48:51

The government and SpaceX refuse to say it failed outright

StrawberryArmada 2018-01-17 14:49:00

Media says the gov said it failed

StrawberryArmada 2018-01-17 14:49:23

If it failed then we lost one billion dollars

StrawberryArmada 2018-01-17 14:49:35

If not why are they saying it did

micbwilli 2018-01-28 03:41:57

I'm not sure where to ask this, but how do you guys feel about common core?

ThisIsChris 2018-01-28 05:12:41

@micbwilli I'm curious about it but don't know much about it. Do you have any thoughts? I used to teach college math classes and some of the freshmen needed to be whipped into shape but I don't know if it has any relation to common core. Though I did have a lot of students asking if I would be "grading based on the correctness of the answers" to which I was like "yes lol why" and apparently a lot of high school students are NOT graded based on the correctness of their answers?? Idk if that is a common core thing or just a their schools thing though.

micbwilli 2018-01-28 05:19:27

I don't trust it. It was brought in with no studies on efficacy. All the teachers on the ground seem to hate it.

I get nervous about a lot of these programs of dubious effect. If the outcome is equality than the mechanism is to bring down the top students, because rasping the others to meet them is not usually a possibility. One of the major backers even said CC was a way to stamp out "white privilege".

Sam Southern - TN 2018-02-05 22:19:14

Does anyone here know Matlab? I’m taking a Matlab class and am super confused

Deleted User 2018-02-06 03:33:43

Did you take matrix algebra aka linear algebra?

Deleted User 2018-02-06 03:34:38

The simpler versions need you to understand basic matrix algebra concepts

micbwilli 2018-02-12 01:51:13

Wrong place. :P

ThisIsChris 2018-02-12 02:44:55

It's appropriate, it's science

Joe-MN 2018-02-12 02:51:50

not for macgoyver though.

Argument of Perigee 2018-02-12 03:16:59

Odd fellow (as to be expected), but it was a decent watch.

micbwilli 2018-02-12 05:25:52

I wasn't saying this above thing was wrong. I made a post here that was supposed to be in another section and I deleted it.

ThisIsChris 2018-02-12 05:32:06

ohh lol

ChillS 2018-03-05 22:42:12

@Sam Southern - TN I know some matlab

Freiheit - CA 2018-03-07 06:03:28

Anyone in the petroleum industry?

ThisIsChris 2018-03-07 17:48:58

@here ^^^

Deleted User 2018-03-07 17:49:35

Im familiar with network engineering in the petrol industry, but I've never worked directly for a petrol company. Lots of BGP.

Brandon Ironside- ND 2018-03-07 17:53:03

@Freiheit - CA I got my degree in petroleum engineering, though I work in aviation engineering at the moment. What you need? Thanks for tag @Havamal

Freiheit - CA 2018-03-07 18:52:36

@Brandon Ironside- ND Looking to start a new career. I want to make my fortune. I think opening Anwar, Gull Island &c. will make for a boom in oil when they run a pipe across the continent.

Brandon Ironside- ND 2018-03-07 18:58:12

@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.

Freiheit - CA 2018-03-07 18:59:31

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

Brandon Ironside- ND 2018-03-07 20:09:18

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.

John O - 2018-03-07 20:27:23

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

Brandon Ironside- ND 2018-03-07 20:32:29

@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.

Brandon Ironside- ND 2018-03-07 20:33:14

there still is work though, just not boom levels

John O - 2018-03-07 20:33:47

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

John O - 2018-03-07 20:34:34

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

Brandon Ironside- ND 2018-03-07 20:41:59

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

Brandon Ironside- ND 2018-03-07 20:43:35

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

John O - 2018-03-07 20:47:36

I'm talking roughnecks

Auf WI 2018-03-07 21:01:06


Brandon Ironside- ND 2018-03-07 21:32:38

Oh, yea close to above number now

John O - 2018-03-07 22:33:47

That sucks.

ThisIsChris 2018-03-14 04:31:16

Happy Pi Day!

Attrition in the desert 2018-07-09 04:58:36

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

Attrition in the desert 2018-07-09 18:20:48

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

Attrition in the desert 2018-07-09 18:21:37

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

ThisIsChris 2018-07-10 12:13:39

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

Attrition in the desert 2018-07-10 16:27:33

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

micbwilli 2018-09-18 01:54:12

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

@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.

Nicholas1166 - NY 2018-09-24 03:37:27

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

YourFundamentalTheorum 2018-09-24 04:23:03

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

if you need halp

Nicholas1166 - NY 2018-09-24 04:31:53

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

micbwilli 2018-10-03 05:19:28

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

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

YourFundamentalTheorum 2018-10-22 06:56:33

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]

ThisIsChris 2018-10-22 07:18:25

@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

YourFundamentalTheorum 2018-10-22 07:18:42

@ThisIsChris quotient field

YourFundamentalTheorum 2018-10-22 07:19:06

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

ThisIsChris 2018-10-22 07:24:17

@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

YourFundamentalTheorum 2018-10-22 07:26:20

the last part is a given.

ThisIsChris 2018-10-22 07:26:24

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

YourFundamentalTheorum 2018-10-22 07:26:44

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

YourFundamentalTheorum 2018-10-22 07:26:51

a lesser degree than f1(x) that is

ThisIsChris 2018-10-22 07:27:59

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

YourFundamentalTheorum 2018-10-22 07:28:10

assume f1 and f2 are of the same degree

YourFundamentalTheorum 2018-10-22 07:28:16

otherwise you don't have the same cardinalities

YourFundamentalTheorum 2018-10-22 07:28:20

which means they can't be isomorphic
