Math PhD shorter than physics PhD?

Click For Summary

Discussion Overview

The discussion centers on the duration of PhD programs in mathematics compared to those in physics, specifically within the context of top US universities. Participants explore various experiences and data regarding the typical time taken to complete these degrees.

Discussion Character

  • Debate/contested

Main Points Raised

  • One participant conjectures that a math PhD is generally shorter than a physics PhD, suggesting durations of approximately 4 years for math and 5 to 7 years for physics.
  • Another participant cites a 1995 report indicating the median time to degree for math was 8 years, but believes it has decreased, while noting that the median for physics was slightly over 6 years based on more recent data.
  • A participant from New Zealand mentions that a PhD in physics takes about 8 years.
  • One participant claims that their math PhD program does not allow students to remain for 8 years without finishing, stating that 5 or 6 years is considered slow.
  • Another participant reflects on their own experience, suggesting that their path from undergraduate to PhD took 17 years, raising questions about how to judge the duration of the entire process.
  • A participant questions the criteria for measuring the time from first year undergraduate to PhD completion, implying variability based on individual circumstances.

Areas of Agreement / Disagreement

Participants express differing views on the duration of PhD programs in mathematics and physics, with no consensus reached on which is generally shorter or the typical timeframes involved.

Contextual Notes

Participants reference various sources and personal experiences, indicating that the duration of PhD programs may depend on specific institutions, individual circumstances, and historical context.

Conjecture: Math PhD is generally(with appropriate definition of generally) shorter in duration than physics PhD. (PhD programmes in US is under consideration and universities in question are say top 10)

Anyone with proof?
I have an impression that math PhD is normally ~4 years
whereas physics PhD is normally ~5 to 7 years

dunno if it's correct though

In 1995, the median time to degree for math was 8 years, according to the NRC (and other sources)

I believe it's lower now.

Last I checked, the median time to degree in physics was a little over 6 years (this is more recent data, I think - look up the AIP site).
 
In NZ a PhD in Physics takes ~8 years, hope that helps
 
we don't keep anyone 8 years who hasn't finished at my PhD math program. I think 5 or 6 is considered slow in math. In the olkd days I heard princeton only allowed 2 years, maybe three. Utah put me on notice after 2 years that I only had one more year to finish my math PhD (but i entered with a masters).
 
Im talking from first year undergrad to ending PhD :redface:

for me maybe, let's see,...ummmm, 17 years?
 
first year to Phd? all at the same school?!?? how do you judge that?
