How is it to work in numerical relativity?

Click For Summary

Discussion Overview

The discussion centers on the experiences and challenges faced in the field of numerical relativity, particularly regarding the balance between coding and fundamental physics. Participants explore the nature of daily work in this area, including the enjoyment derived from overcoming challenges and the potential for gaining insights into fundamental physics.

Discussion Character

  • Exploratory
  • Technical explanation
  • Conceptual clarification
  • Debate/contested

Main Points Raised

  • One participant expresses concern that daily challenges in numerical relativity may primarily involve coding and numerics rather than fundamental physics.
  • Another participant, who has experience in numerical simulations, suggests that daily problems are indeed mostly related to numerics and coding, with limited insights into fundamental physics.
  • There is a shared sentiment that the work, despite being "grunt work," can be enjoyable and rewarding, particularly when achieving new results after overcoming numerous details.
  • A participant notes that this perspective may be difficult for students or younger individuals to grasp.
  • One participant relates their experience in finite element analysis, emphasizing the challenges of model meshing as a common issue in their work.

Areas of Agreement / Disagreement

Participants generally agree that daily work in numerical relativity involves significant coding and numerical challenges, with some expressing that this does not detract from the enjoyment of the work. However, there is no consensus on the extent to which insights into fundamental physics can be gained.

Contextual Notes

Participants mention the potential disconnect between expectations of gaining fundamental insights and the reality of dealing with technical challenges, highlighting the subjective nature of enjoyment in the field.

  1. the problems/challenges that you have to face daily are mostly related to code issues with the physics itself?
  2. Is there room to improve our knowledge of fundamental physics while working on it?
  3. Do you enjoy doing it? why?
I'm asking this because I'm considering working on numerical relativity but, although I really enjoy general relativity, I'm afraid that the problems that I will have to solve working in that field are mostly related to numerics and coding. Thank you in advance!

I don't work in numerical relativity, but I have worked in numerical simulations in several other areas of physics. I can almost guarantee that the problems you will wrestle with on a daily basis will be almost entirely related to numerics and coding. Insights in fundamental physics will be few and far between. As Edison said, "Genius is one percent inspiration, ninety-nine percent perspiration". I think this is true in any field. Much of what you do on a daily basis is "grunt work". In my opinion, this doesn't make the work less enjoyable or less rewarding. On the contrary, when you achieve a new result, the fact that you have slogged through hundreds of trivial details to get there makes it all the more rewarding.

I think this is really hard for students (or generally, young people) to understand.

I can relate 100%, most of my work is generally in finite element analysis and a lot of my day is just trying to get the damn models to mesh, lol.
