In physics, a box is always one-dimensional, unless the person is very ambitious!
Pro tip: Only send emails with a one hour buffer into the future, so regret has time to creep in and you can delete your disastrous email before it causes damage.
And the one that drives me nuts: A professor who continually erases and adjusts the bits of their letters while talking, as if the smudge-fest that ensues is clearer than the original writing!
Sorry, it’s a knee-jerk reaction.
My favourite example of this is when a researcher asks a question after a presentation that is all about showcasing their own knowledge instead of engaging in a dialogue.
I wonder how many professors employ the strategy of building the train tracks as the train speeds along them?
If you want to learn a topic today, the resources are much more plentiful than even a few decades ago. The internet has given us wonderful resources to learn from, including some which leverage internet technologies to provide animations and teach topics in a much more interactive way. This is particularly true for mathematics and physics, which have been entrenched in dry textbooks that are a chore to read1 for much too long. The tools…
You would be surprised how many people suggest I should just use a neural network to train the hyperparameters…
The conversion factor between the time you think it will take and the time it will actually take is somewhere around 1/0.
I think this is one of the few measurements I’ve made as a theoretical physicist where I can claim absolute certainty: 0 ± 0!
