32+1 I really sympathise with this feeling. My PhD was very computational rather than theoretical (physics) and nowadays I too make silly/trivial algebra and calculus mistakes. I'm hoping there's a better solution than just revising undergrad algebra/calculus and doing practice problems...– astronat supports the strikeCommented May 22, 2021 at 14:32

16'physics students only use certain mathematical methods, so once you learn how to do those (all of which can be done via Mathematica)' Caution: I once wasted several months examining the details of what I thought was a novel solution I'd got to a theoretical physics problem, but was actually an artefact of two independent computer algebra systems giving the same wrong answer for the lead coefficient in a Fourier series ansatz for a partial differential equation. Don't get me wrong, I remain a big fan of computer algebra, but one always has to have some human verification.– Daniel HattonCommented May 22, 2021 at 15:49

1@DanielHatton Thanks for sharing your experience. That is true; human verification is important, but even in that case the mathematics used in most of (bio)physics research is really not advanced. It is just a re-usage same method in different ways over and over again.– OurCommented May 22, 2021 at 15:52

3this is just to say that I know how it feels and my sympathy is totally with the TS. Whether you gain your skill back or not, I hope you find a way to make your peace with it. Realizing that you were good at something but aren't anymore can be a terrible feeling.– sleepyCommented May 22, 2021 at 17:44

create code fences with backticks ` or tildes ~
```
like so
``` -
add language identifier to highlight code
```python
def function(foo):
print(foo)
``` - put returns between paragraphs
- for linebreak add 2 spaces at end
- _italic_ or **bold**
- quote by placing > at start of line
- to make links (use https whenever possible)

A tag is a keyword or label that categorizes your question with other, similar questions. Choose one or more (up to 5) tags that will help answerers to find and interpret your question.
Use tags that describe what your question is about, not what it merely relates to. For example almost every question on this site is eventually related to research, but only questions about performing research should be tagged research.
Use tags describing circumstances only if those circumstances are essential to your question. For example, if you have a question about citations that came up during writing a thesis but might as well have arisen during writing a paper, do not tag it with thesis.
- complete the sentence: my question is about...
- use tags that describe things or concepts that are essential, not incidental to your question
- favor using existing popular tags
- read the descriptions that appear below the tag
If your question is primarily about a topic for which you can't find a tag:
- combine multiple words into single-words with hyphens (e.g. graduate-admissions), up to a maximum of 35 characters
- creating new tags is a privilege; if you can't yet create a tag you need, then post this question without it, then ask the community to create it for you
