I'm curious, is there a "Ph.D. bubble" in math that is similar to the one in physics? Specifically, what percentage of graduating math Ph.D.s end up getting tenure?
98whbf said:I think the OP might be referring to there being more people being awarded with Ph.D's every year than there are jobs opening.
Vanadium 50 said:Yes, but that's hardly a "bubble". A model where every faculty member has 5-10 students who then all graduate to become faculty members with 5-10 students is clearly unsustainable. It's simply not realistic to expect that a PhD means a faculty job at a research university. Most PhD's move on to industry - which, IMO, is a healthy sign: it means that a PhD has value to other parts of society.
hamster143 said:There's no immediate reason to conclude that a PhD in physics or math has any value whatsoever outside academia.
No way! The whole point of getting a PhD is to open doors to interesting, challenging, rewarding, and stable jobs.hamster143 said:I can't agree with that. The whole point of getting a PhD is to do research for a living.
That governments and industry provide the funding needed to make it possible to produce many times more PhDs than are needed by academia belies your claim.There's no immediate reason to conclude that a PhD in physics or math has any value whatsoever outside academia.
That is simply not correct. One of the main reasons why governments are willing to fund the training of so many PhDs (via funding agencies) is because they are needed in industry. Where I did my PhD the vast majority of the PhD students had no intention of ever going into academia. Most of them ended up working in the telecom industry, some went into finance etc.
Even if you do your PhD working in an "exotic" field you still pick up a lot of useful skills. One large company which had an R&D facility near my university were actively recruiting PhD students that had worked in string theory, not because they were interested in Branes etc but because they had found that they were really good at calculating various properties of radar systems.

hamster143 said:I see this as a big problem. This is like training lots of people to play violin, because the ones that succeed will be proven to have agile fingers and keen sense of hearing and thus could be retrained to do jobs that require either (or both), even if they don't touch the violin for the rest of their natural lives. It makes no sense to study string theory and then go calculate properties of radar systems for a living - it's better to get a 6 month course on radiolocation followed by hands-on training.
Governments provide non-directed science funding that is available to all qualified applicants to spend more or less as they please. NSF budget is X, the share of this budget that is allocated to physics is Y, and X and Y are determined by the state of national economy, by the whims of politicians, and by historical trends.
A further proof is that physics students have to be paid to work on their PhD's. if PhD had significant weight in the industry, we'd have people piling up into physics programs and taking on sizable student debt

If you invest 5 years into a Ph.D. and perhaps 4 more years into a post-doc, you should spend that on knowledge and skills that you will need for the 30 years that follow.
f95toli said:Also, if one were to follow your line of reasoning to its logical conclucsion everyone that does a PhD in a certain field should then continue in that field. It is not at all unusual for people to move to a complettely different field of reseach after a PhD even if they stay in academia.
f95toli;2420066I think the same thing applies to quants. The reason why people with PhDs in physics or math end up in that job is that we are the only ones that know enough about math and modelling. There is no way somone who has only graduated from busines school have learned enough math.[/QUOTE said:People with master's degrees generally do know enough math to do modeling, however where people with master's degrees can run into trouble is if the rules change if it turns out that you need to teach yourself some math that no one has ever taught you.
kote said:There is an institutional problem in academia that is causing an oversupply of PhDs.
Notice at no point has the good of society or the student been mentioned. It's simple economics and it's uniform across specializations that are and are not useful in the work force.
twofish-quant said:I really don't think that society has an oversupply of Ph.D.'s. There is a huge problem in that Ph.D.'s are being taught that the "normal" thing for a Ph.D. to do is to get a job in academia, but that's something different.

Yes there is. If you don't have teaching and research assistants, you don't get funding. If you don't get funding then your salary doesn't get paid. Both the people that you mention (Einstein and Perelman) are funded by systems that are very, very different from the system that most university professors get funded.
I wouldn't say it's a "bubble" as much as a "ponzi scheme."
No it's not. People with bachelors in finance just don't have the mathematical or research skills to do quant work. One thing that makes the Ph.D. different from the bachelors is that you are *creating* knowledge. I have no clue what mathematical techniques are going to be used in finance next year, neither does anyone else. Ph.D.'s are used to situation where there isn't a textbook. Most people with bachelors are not.
hamster143 said:Right, the system is set up in such a way that one side effect is overproduction of Ph.D.s. Since Ph.D.s don't really bring any money into the system (NSF & other federal funding excluded), it is perfectly possible to produce fewer Ph.D.s and employ more research professors on the same budget.
A string theory Ph.D. would spend 2 years just learning basic tools of the trade up to and including QFT, and then 2 more years getting a partial picture of the more recent developments, which leaves him one year to write a thesis, i.e. "create knowledge". And then he gets a job in an investment bank, learns a lot of new stuff, and forgets all about QFT and string theory.
Someone who gets a Ph.D. in finance instead, studying financial tools and models and trying to create knowledge there, would probably become a better quant in less time than someone whose brain is loaded with conformal field theory and other esoteric stuff with narrow scope of application.
Out of curiosity, is there still the job market for quants on Wall Street nowadays? I'd have expected that field to shrink significantly.
Also there is student tuition which requires massive number of teaching assistants. I really don't think its possible to have fewer Ph.D.'s and more research professors since you end up needing a lot of graduate students to do grunt work. A lot of astrophysics research (and for that matter financial programming) involves staring at one hundred thousand lines of source code trying to figure out why energy doesn't balance. For this type of work, you need lots of highly skilled warm bodies.
Also with some exceptions, the quantitative research divisions of most investment banks just don't hire finance Ph.D.'s because they don't have either the mathematical or the computationu canal experience to run the systems. If you can handle QFT, then presumably you can handle stochastic differential equations and mortgage default models... The problem with most finance Ph.D.'s is that very few of them have ever programmed a supercomputer, which is a problem when it comes to running the grid that's at the heart of every investment bank or major hedge fund.
One other thing is that physics and math Ph.D.'s are willing to work relatively cheap. You give a physics/math Ph.D. a $160K job, and they will kiss your feet whereas most finance Ph.D.'s from big name schools will laugh at such small piddling sums.
hamster143 said:I doubt that many Ph.D.s do teaching assistance. For starters, you can't be a good TA unless you're a native English speaker (the best you can do is grade homework).
A shift towards 1:1 student-teacher ratio would involve more grunt work for professors, but that's all for the better.
That's an interesting perspective, though a lot of it seems to reflect deficiencies in finance Ph.D. training rather than the inherent value of physics Ph.D.
Physics/math Ph.D.'s do tend to be a little out of touch with the real world. Eventually they'll realize that $160K in Manhattan for a married couple with children buys worse quality of life than, say, 100K in Charlotte...
Well no one I know with $160K has a house in Manhattan, everyone lives in either New Jersey or Queens. Also you can work in Manhattan and fly to Charlotte on the weekends.
Also $160K is something of a basic salary for a quant. There is a long tail for how much money you can make. If you have a physics Ph.D. there's probably a 1 in 50 chance you'll end up making $1M/year in finance, but that's higher odds than in any other field.
hamster143 said:As far as I know, there are basically no good public schools in Manhattan, which is why people end up commuting to Manhattan from NJ and White Plains and other remote places, 40 minutes one way ...
If you're going to live in Charlotte, rent a studio in Manhattan, and fly back and forth four times a month, that might cost more than the difference between 100k and 160k after-tax.
whereas you could live in Charlotte or Portland or some other backwater city, have a job as an engineer that pays 100k, and live in a big house on a half acre lot within a 15 minute drive from work.

Locrian said:I don't think you can actually back this statement up. All you can say is that most don't get into academia, and some move to industry.
Nobody really knows the proportion of the people who get a PhD that move to industry.
Locrian said:Nobody really knows the proportion of the people who get a PhD that move to industry.
An academic position at a college or university remains the prevailing long-term employment outcome to which most new physics PhDs aspire. Although this is considered by many as the traditional career path for physics PhDs, in fact the private sector and the government historically employ the majority of physics PhDs. Twenty-four percent of the new PhDs aspired to careers in the private sector and 10% had a long-term goal to work in a civilian government or national lab position.
union68 said:Uh...what exactly is a quant? Can anybody refer me to some information on this?
kote said:http://www.aip.org/statistics/trends/highlite/emp3/table3.htm
kote said:http://www.aip.org/statistics/trends/highlite/emp3/table3.htm
60% of the potentially permanent positions taken in 05 / 06 were in industry if I'm reading this correctly.
Vanadium 50 said:The AIP keeps statistics on exactly this sort of thing.
twofish-quant said:Also if it is the case that "no one really knows" then this is really alarming and frankly irresponsible.
twofish-quant said:I really don't think that society has an oversupply of Ph.D.'s. There is a huge problem in that Ph.D.'s are being taught that the "normal" thing for a Ph.D. to do is to get a job in academia, but that's something different.
If you look at unemployment rates for Ph.D.'s. I don't know of any physics/math Ph.D. that has had any problem looking for a job, once they looked outside the academy.
The problem is that if the solution is "make society less educated" its probably not going to cause good things to happen. The only real solution I can see is to make Ph.D. students and their advisors more aware of life outside the academia.
What I think is going to be really interesting is that if you have more Ph.D.'s outside the academia than inside, this will likely change the power structures within the academia.
Locrian said:My school also kept track of their graduates. However talking with the older PhD's, it became clear to me that many names were not on the list. People who couldn't get a job often disappeared. Maybe they got one, but no one knew. Your school may not have this problem, but this type of selection bias plagues post graduation data.
mathador79 said:Interesting discussion. I believe that there is indeed an oversupply of math phds. There are, simply put, many more phds being produced than there are available academic jobs.
In my opinion, if graduate schools wish to continue overproducing phds, they should do a better job of preparing their students for the reality that many of them will not find suitable academic employment, and should provide alternative career counseling and job placement services.
twofish-quant said:The system is pretty screwed up. One thing that I think will help a lot is if you force people to sign a piece of paper saying that they realize that if they finish the Ph.D. program, it is rather unlikely (i.e. 1 chance in 10) that they will end up getting a tenure track position.
vanesch said:Well, when you're 25 - 30 years old, and in a PhD program, you might be considered intelligent enough to find out your job opportunities for yourself, no ?
PhD students aren't mentally retarded people who need a protected work place.
When you open a restaurant, nobody requires you to sign a paper that you realize that if you don't have customers, you might end up out of business.
Of course, making some information of the real job market available can always help, but one shouldn't flee one's own responsibilities in the choices for one's career path. With kids, I agree, but not with intelligent adults.
Vanadium 50 said:This is quite different from my experience. When I was a student we certainly didn't expect a permanent job in academia.
We could see students graduate with the PhD equivalent of the "gentleman's C" - granting a doctoral degree for some work that wasn't the best, with the understanding that the student would not ask anyone for letters of recommendation for postdoctoral postions.
That said, there was an attitude among the grad students that "this can't happen to me" - they would believe that half of them would move to industry (which is about what it is) but they wouldn't believe that they would be in that half. And as it happens, 50% of them were right.
And that's not even taking into account competition from for-profits like University of Phoenix. University of Phoenix scares me because unless someone comes up with some alternative, it's where higher education is moving toward, and it's not a vision that I think is appealing.
symbolipoint said:Would employers of graduated candidates have an influence on this trend?
twofish-quant said:Which is why jobs in investment banks or medical imaging or whatever are perfect. I'm basically writing the same sorts of programs that I am in Wall Street that I did in graduate school. Only with more money.
