There should be at least two major theories; MOND (Modified Newtonian Gravity) and dark matter. The reason dark matter theories are currently regarded as the better theory is because of MOND can not explain e.g. bullet cluster (predictions are wrong), whereas dark matter can. Mind you, dark...
Hi!
I'm a first year MPhil student starting my project on black hole growth and dark matter annihilation. I have been struggling with some fundamental things such as getting connected. I would like to be able to discuss my work with people but I am not really sure where to start.
Hi,
Thanks a lot for all the replies. I'm sorry I didn't reply earlier.
@micromass
That's actually a very unexpected reply, and I tend to agree with you. I self-study quite a lot, so in some sense I was hoping that the best proposed method would involve working things out by yourself. I don't...
I'm especially curious if there are any people who actually start off with Sage/Mathematica, e.g. they want to solve a problem and they open up Mathematica and start working on it right off the bat without first formulating the problem on pen and paper.
Hi!
I'd like to discuss your experiences with pen and paper vs software. Especially young people are welcome to join the discussion :)
I'm wondering if there are people who do *most* of the symbolic calculations on a computer. I am very familiar with pen and paper and I've been wondering...
I have come across a serious problem in my studies. I like to self-study, but I am wrestling between different study methods.
I have at least three options on how to read material:
Read through it
Derive every formula yourself (~6x extra time)
Read the title and outline, and re-invent the...
There are a lot of Q&A about research in physics here. I'd like to know more about examples of your own career path. Did you change your subject, how did it work out? Did you do work mostly independently, and if so, when did you start? How did you pick your school?
I'm a 23 years old physics...
Active vs passive learning:
There is research that people tend not to learn much by re-reading a book/chapter etc. On the other hand, solving problems tends to be useful for learning.
This made me wonder, is there research into passive learning by going through various different sources...
Hey, I'm sorry to revive a dead topic, but does anyone have experience with SageManifolds (http://sagemanifolds.obspm.fr/)? I would especially appreciate a comparison of SageManifolds to Mathematica. I am considering whether I should use free software or simply buy Mathematica.
The reason I...
Now that the conversation is starting to go into an interesting direction, does anyone know of tested methods to contribute the work evenly to a group? E.g. keeping meetings based on the effort done or something similar?
Does anyone happen to know a website where you can start a discussion with e.g. your colleagues about a very wide, unspecified topic or personal topic (e.g. research proposal which has not yet been decided), but which could still be documented and viewed publicly?
I hope I am posting in the...
Hey, thanks a lot for the helpful post. I really appreciate it! I particularly liked the fact that you pointed out that a strong student may dominate the activity. I remember that when I was studying in a group doing experiments we also encountered a a similar problem; one student was...
Thanks Chronos.
Yes, I mean CERN. What do you mean by macroscopic neutron star sized experiments?
I'm sure you can dig something up.
Cheers. The truth is that there are also many theorists out there making very strange theories without any predictions or backup from observations. Some even...
Thank you for your answer Drakkith. I was referring to the process of building further while testing. One can evaluate the pay-off of building and testing a model. This pay-off can be huge, minimal, or somewhere in-between.
Perhaps I can elaborate; I would like to know if putting much effort...
