This isn't about ego. There's simply no point in choosing CS if you shy away from math and won't be working in a field where CS skills are required. You wouldn't enjoy it and consequently wouldn't allow yourself to apply CS methods. There's nothing wrong with connecting databases to webservers. People want that done. It's just not computer science.See, and that is the problem. Most jobs today in proramming require a BS in CS. Yet the majority of jobs I see have requirments like:

Backend developer -Must have BS in Computer Science -Must have 3-5 years Java experence -Must have experence in Oracle, SQL server, etc -Must be able to write SQL code for enterpise applications.

You don't need uber math skills to write good SQL or Java code for a database application. I found after college that while my math and writing skills had improved since high school, my database knowledge was lacking so I went to a technical school. There really should be some sort of IT degree that has a focus on practical knowledge rather than mathmatics. You will use high level mathmatics if you are working on video games, or CAD applications. But most programmers end up writing database interface tools.

I'd like to see some type of IT degree that taught programming, networking, and troubleshooting. I'd rather hire a programmer that had a strong foundation in networking concepts than one who aced calc 3.

Hell, they should also stress English judging by many of the programmers I've met.

Even if you don't use the computational aspects of math it doesn't mean you aren't using math or that math isn't necessary for certain CS fields. Math is the basis of all CS. Without a good understanding of math and the critical thinking skills that go along with it a person in CS becomes the type that just gets the job done. A person with strong math skills is much more valuable.

And that's all bullshit. Believe me. I'm a computer science major, and I connect web sites to databases. Everything that you do in the business world (business apps, yada) has very little to do with pure computer science.

The closest thing to it is probably doing the DB work itself, and making sure that your tables are normalized, and that you have the keys / indices done correctly. Sorry, but everything in your list is basically just a concept in programming, which you can learn outside of the realm of computer science.

If you get deeply into the science of Computer Science, you can certainly get into some math. But, it is important to note that practically no one gets employed as a computer scientist (except for people who stay in academe and study and teach Computer Science).

Most people going into CS expect to get jobs as systems developers of some sort. 'Code monkeys' might be the bottom of the pack; frequently they are just trained tool-users who write snippets of code behind buttons.

But to be a great developer is to be a master of a craft, not a scientist. This particular craft is mental - it is, as you imply, a matter of critical thinking and problem solving. It is being able to look at the world in different ways and being able to see how to express an aspect of the world using the tools of your craft. It is a craft with many principles and design patterns and ways of looking at the things.

To be a great developer requires talent. Picking candidates that are strong on math may be a useful way of identifying people with the talent. (This approach screws people like me, however; I believe that I have a great deal of talent in the craft, but my brain crapped-out after basic calculus.)

The vast majority of developers require no more than:

Sure, if you are getting into signal processing or astrophysics or a variety of other areas, you need lots of math. But that isn't where most people are going. If you are, and you are into math, great; otherwise, don't sweat it.

-Because that person might work in other areas of development eventually. Did you hire the person for ONLY their database-to-webserver knowledge? Was that shortsighted? Maybe you'd rather have a well-rounded and generally smart person to solve those new problems.

We have a very rigorous hiring program at the firm I work for. We look for intelligent people with a wide base of skills who we think can easily adapt to new problems and environments. We DON'T look for specific knowledge in anything but our most senior positions. We have had wild success in finding very talented people because we are not looking for a person with skill A. How long will skill A be relevant for anyway? Will the person with skill A be able to do good work if we try to teach him skill B later? That seems pretty important to me.

So the question is really: what are the most valuable qualities that a new hire can have? If your firm thinks that 3+ years of java experience is the most important quality a new hire can have, then I really don't want to work for them. I have over 3 years of java experience, but I in no way consider that my most valuable quality as an employee.

Anyone who thinks programming is "wiring front ends to databases" is probably a coder. Yes, there is quite a bit of that kind of work in the business space, but a programmer will not wire your database to a GUI: they will come up with tools to do so more effectively. Similarly, anyone who thinks "skill X" is the be all and end all of programming is probably a coder. (I once interviewed a guy who was pretty good with Oracle. Commanded a six figure income. When he found out that the offered project used SQL server 2000, he mocked our company, to our face and to the niche community we work for.

I think the new tendency in the IT industry is to have well-rounded people who can do a good technical job, but still perform passably at the graphic design and copy writing stages. I'm not just talking about Web Development here. Every area of IT is approaching this point.

As deadlines and Time-to-shipment get smaller, programmers are getting thrown more to the forefront of the development cycle. This means dealing with humans, whether it be through well structured language, fanciful graphic design or good interface design. A lot of people are still stuck in the "I'm a rilly good coder, I don need that language stuff aniways" attitude, and I believe that is detrimental to the industry as a whole.

After 14 years in the industry with a BSEE and MSCS, my company closed it's St. Louis office in late 2001. I was out of work for 7 months in 2002 and underemployed for a year and a half after that. I have you're so-called "wide base of skills," but they weren't the right ones. Companies here in St. Louis were not at all interested in poeople who can "can easily adapt to new problems and environments," they were looking for those specific technologies and if you didn't have those 3 years of J2EE experience, they didn't want to even acknowledge your existence.

Of course I attribute this to the typical HR department, who wouldn't know a good engineer from a hole in the ground. So their method of separating the wheat from the chaff is a score card based on what technologies you have on your resume. So even though I had done Java and was well acquainted with OO through my experience and schooling, they wouldn't even talk to me because I didn't have "work experience" with J2EE.

Some of us who have families to support don't have the option to just walk away or cherry-pick companies. We're forced to take what we can get. This attitude runs rampant through corporate culture.

Knowing good math.. makes you a better programmer. I would go as far as to say that computer science _is_ math. Knowing how to hook up a DB to a web front-end is not computer-science. It's a trade skill, like plumbing.

The difference between some web-scripting guy, and a guy who knows CS, is like difference between an automechanic and an automotive engineer. The engineer might not be able to fix your engine, but he understands the workings of it much better than your average mechanic.

From my perspective, being some random code-monkey is not too different from working at McDonalds. Pay might be better, but the work is still shit. Having a solid CS grounding lets you work in places and on problems that are actually _interesting_ and challenging. It allows you to actually contribute something new to the body of knowledge associated with computation.. or apply it well to some novel field.

I can pick up and learn a new language or API given a few months. It would take years of focused study for a random PHP programmer to acquire the knowledge I have.

Not to say that I'm special or anything.. but I've spent 5 years working my ass off to get myself to a proficient level in this area of study.. and most people who want to reach that same level will also have to spend several years doing it. It's just a question of wether you decide to do it early in your life (university), later in your life, or not at all.

But it's definitely worth it.

I don't know Quake personally (I'm not into video games at all), but I assume that it's another one of the 3D videogames where your surroundings change with your perspective.

That requires loads of matrix transformations directly out of linear algebra [falstad.com]. It sounds terrifying, but it's just about having a group of numbers called a matrix. By multiplying them with a bunch of (x,y) coordinate in a certain order, you can do all sorts of warps and shrinks and stuff. If those (x,y) coordinates correspond to a bitmap of an object, you've just warped or shrunk the object, exactly as you'd have to do in a 3D maze or similar.

Then, there's calculus. There are two courses *everyone* should have to take in high school - auto mechanics (so you know how to change a tire, among other things) and calculus. Calculus means "small stones", as for counting. It's all about rates of change. You could tell the speed of your car by looking at your odometer and your watch, but that will give you only the average speed over a given time or distance. The speedometer, on the other hand, gives you your instantaneous speed - which is the derivative (calculus term) of your position (odometer) with respect to time. This makes sense when you think about it: speed is the rate of change of position.

(Actually, it's velocity, but that's a whole other kettle of fish if you don't know about vectors from Linear Algebra yet.)

Don't worry about the math. It's usually the easiest course in your university schedule - and I tell you that as someone who failed high school math classes constantly and who dropped out of high school because of math (that's a long story, though). Math *is* your friend. How's that? You can be guaranteed that if you do all your homework, you will get an A+ in the course. That's it. No reading, no stupid assignments which get marked by TAs who know less than you, nothing. It doesn't even matter how good or bad your teacher is. Just do all your homework and you'll get an A+. It's a non-linear relationship, do 50% of your homework (every second assigned problem) and you'll get a B+. Do 25% of your homework and you'll get a C+.

As an EE, I had to take 7 university level math classes.

CS students are blessed/cursed with the likelyhood that some of the math that you learn will be from your CS department. It doesn't make matrix multiplication that much more pleasant, but it is interesting to write a simple search engine algorith that matches a terms in a documents to a vector of search terms.

I disagree with you on stats class. We were allowed to use Excel to do some of the gruelling number crunching for us once we'd done a handful by hand. Now, I can't do any of it by hand from memory but I'm ok with a book. I do understand what they heck is going on with some basic stats work and have a feeling for how to go about doing some vaguely interesting analysis of things I encounter.

I am tired of telling them that throwing faster hardware at the problem will not help, as a faster machine will only choke the database harder.

The only students that really succeed at math in U.S. schools are the ones that have the desire and ability to teach themselves.I don't completely disagree but there are a lot of issues; it's not just that there are professors who aren't interested in teaching. I'm an assistant professor in a math department. I teach numerical analysis to classes comprised of about 75% computer science majors and the rest math majors. There are several things beyond the control of a professor that can impact the quality of instruction. One of the biggest is that many of the students are not interested in the topic; they just want to pass to meet their departmental requirement for a numerical analysis course. Hence I get students trying to copy homework or codes. Just last week I had two students turn in spline code that was a bad C translation of Fortran code. I haven't hunted down the source but their codes were identical and neither student knew Fortran. Having to check for this sort of thing takes time and does not make it easy to teach.

To make matters even worse, the students put off taking numerical analysis until they are about ready to graduate by which time they have forgotten much of the calculus they learned in their first two years. In less mathematical disciplines, many students put off taking calculus and end up forgetting their high school math. And that's assuming the high schools did an adequate job preparing them for calculus in the first place.

And then there are teaching load issues. Math departments generally teach more courses than any other department with the exception of English. Everyone has to take some math. Proportionally we are overloaded with classes to teach. Further university guidelines on tenure are often not written to take this into account. Mathematicians at many universities are expected to write as many papers, get as many grants and supervise as many graduate students as computer science professors while teaching more courses. For some reason this doesn't always work even when the professor has the best of intentions.

The closest thing to a solution that I know of is to hire non-tenure-track lecturers to specialize in teaching calculus, college algebra, etc. That is already done at most schools but often there are rules about retaining such faculty. Even when they are doing a great job (and many do---teaching is what they do and they take it seriously) university policy can prohibit renewing their contracts past an arbitrary time (e.g. 3 years). This makes it difficult to maintain a staff of good teachers.

There may be professors slacking off but in my (possibly biased) opinion the institutional problems are more common. Students shouldn't be able to put off taking math. The universities should hire some portion of permanent faculty that is dedicated to teaching. And promotion guidelines should be written to reflect what the university realistically expects from both tenure-track and non-tenure track faculty in each department.

Possibly that's more griping than you wanted to hear about university politics...

In a Linear Algebra class, it is useful to check yourself by computer, and you can really get a good understanding of operations like inversion, Gaussian reduction, and determinanat computation by writing the algorithms.

Moving on to a course in Nonlinear Dynamics, a computer is almost an essential tool for modeling dynamical systems that can't be solved in closed form. I had to write my own methods in Mathematica to model these sytems, seek out points of equilbria, and examine their stability. Want a hard core programming exercise? Write a program that will attempt to find Lyapunov functions for a given dynamical system - that will really test your self-worth as a programmer.

Even in a course like Abstract Algebra, you're going to need a grip on programming to get a deep understanding it, for example, reducing polynomials in GF(256), as is done in Rijndael. You can sit there and mechanically do it out by hand if you like, but if you want to get anywhere, use a computer.

If you have the chance to take calculus in high school, I may surprise you with my advice. I would not automatically jump at the opportunity for a couple reasons. Please forgive me as I climb onto my soapbox, but keep in mind that I am a math teacher and I know a lot of this from experience.

First, high school calculus teachers tend to be the teachers in the math department the longest. The problem with this is that while these teachers are more experienced, they have been away from calculus longer than the other math teachers in most cases. Besides that, these teachers are often near retirement and may not be as motivated as younger teachers.

Second, calculus is the upper-crust of high school math. In college, it's one of the lowest math classes offered. This results in a completely different teacher mentality. A college calculus teacher will be used to working with struggling students because for many of them, that is the toughest class they will ever have to take. But high school calculus teachers will be more used to working with the top students in the school. If you aren't especially gifted in math, you may find that you don't get what you need from these teachers.

Here's the problem with those ideas:

1) In Calc I in HS, you're looking at a class of 30 people. 50, max. In Calc I in college, you'll likely be in a class with something on the order of 100-200 people. See, *everybody* takes Calc I their first year, not just the comp. sci's. All engineering majors, all the math geeks.. Hell, even English majors probably have basic math as a requirement... So most of the time, it's a big class, usually a seminar type of deal. If you're having a hard time with it in there, then you'll also likely need to take another not-for-credit class where they can give individual instruction or take some extra tutoring on the side. Whereas in high school, you've not only got a smaller class, you've got an experienced math teacher, who likely knows his stuff, and you've got a year to learn it as opposed to 1 semester only. Okay, so the HS teacher may be less motivated, but you've got a longer time period, a smaller class, and you're in that class with the top students in the school (who can probably help you out somewhat) instead of in there with everybody in the whole school (who likely need just as much help as you do).

2) Yes, calculus is the upper crust of high school math. It's also a heck of a lot easier than a college level math class. But here's a thought: The high school class doesn't usually count towards your college GPA, while the college level one does. What's so bad about taking it twice? Take the high school calc if you can swing it, then take it again in college. You may still have a hard time in the college calculus, but it'll be somewhat easier because you've got at least some background to it already.

You would not believe how much math is involved! There was one proof in a whitepaper I read that used calculus, algebra, trig, linear algebra, and geometry. In one proof!

My recommendation: take all the math you can. Make sure you take linear algebra (vectors/matrices), trigonometry, calculus, probability, statistics, and anything else that looks interesting.

Why does a CS major need math? Let's see:

Graphics engines - trig, geometry

Physics engines - Calculus, trig

Many students take this class before Data Structures and they remark that it makes the distinction between Interface and Implementation much easier for them (especially since search algorithms are all on various linear orders). They also know how to design APIs cleanly without having to write the program first.

The point I am trying to make is that you should not just take math because of the techniques you learn from it. (This is anecdotal, but) When I was at graduate school at Cornell, almost every math major I met who started programming after taking a lot of math classes was a stronger programmer than anyone who started programming first.

In addition, many of the techniques and methods, like difference equations, parallel those in calculus, so it can reinforce what you've learned in calculus.

My cousin, a professional mathematician, recommended that I retake calculus in college. She said that she hadn't really understood calculus until advanced calculus in grad school!

However, in order to abstract, we have to dot all of our i's and cross all of our t's and lay out the law on when the abstraction will or will not work. Sounds familiar?

The beautiful part is that there is no compiler and no test suite you can run against your "programs". You have to do it all in your head. If programmers were able to better predict the behavior of their programs, or if they were to write their programs in such a way that it could be done, then we would have far fewer bugs, or at least debugging would be easier to do.

So, if you are a pro at math and physics, then programming languages is a toy to you.

Why physics, and not just math? Math is programming for programming's sake. Physics is programming tied to reality in some way. Or in other words, you are practically applying the discoveries mathematicians make, and fudging stuff they haven't discovered yet, all in the interest of getting an answer that agrees with the way stuff really is. Physics adds that dimension of "reality" that is inescapable, just like real programming has the shadow of the "user" or "API" or such that is inescapable and must match what people want to see.

There is one area that math and physics won't teach you, but it is easy enough to pick up as it is a rather simple system compared to, say, Thermodynamics or Quantum Mechanics. That is the way computers really work and the limitations thereof.

You can make a living at programming without knowing much about math. Most programmers can get along with some basic algebra skills, and understanding boolean logic.

The long answer is that the question asked in the context of a discussion of computer science shows a lack of understanding of what the field of computer science is. Computer science is not about java or c# or sql. Computer science is about understanding and analyzing why a computer acts a certain way given a certain set of conditions. It is about understanding the best way of instructing a computer to perform tasks. Its about knowing that a computer cannot perform certain tasks no matter how well it is programmed. What does this have to do with math. All of the tasks I mentioned are addressable with some mathematical analysis. A computer scientist will write a program to demonstrate a concept or test a theory. A computer scientist will not write a program to do inventory controll for walmart, unless there is some novel or interesting problems in that task that no one has tackled before. In general someone graduating with a cs degree is well versed in theory, and will have to catch up on the practical aspect of the field. For example, I graduated with a CS degree having only seen one Design Specification Document. I now deal with them every day.

There are many trade schools out there that will give you training in a group of technologies (c#, sql, java, html) and call it a computer science degree. The best of these schools turn out software engineers (a very good skillset to have) the worst of these schools turn out people who are capable of passing a cetrification exam and that is it. In general these guys (the software engineers)can jump right into the business of writing software much more easily than someone with a straight cs degree. However the devry graduates tend to have trouble designing and understanding larger systems, and the ramifications of their decisions within those systems. I find this due to the lack of theoretical underpinnings to their education.

Don't get me wrong. I'm not saying every trade school graduate is not capable of dealing with and analyzing large system analysis. I'm just sayind that in my experience that these graduates come out a little less well equiped for the task. And yes I know several CS graduates who are dundering idiots, so you don't have to tell me about your experience with one.
