    A professor at my university tried that, but the students quite quickly made a huge fuss, got the principals office involved, and the universities lawyers informed said professor that what she was doing was illegal, and that she should stop before she got any more trouble. She stopped.





  • Assuming

    • cylindrical human, 2m tall, 25 cm diameter.
    • air displaced from the point you teleport to is instantly moved to form a monolayer (1 molecule thick) on your surface.
    • The displacement of air is adiabatic (no heat is transferred, which will be true if the displacement is instantaneous)

    Volume of displaced air: ≈ 100L = 0.1m^3 At atmospheric conditions: ≈ 4 mol

    Surface area of cylindrical human: ≈ 1.58 m^2 Diameter of nitrogen molecule (which is roughly the same as for an oxygen molecule) : ≈ 3 Å Volume of monolayer: ≈ 4.7e-10 m^3

    Treating the air as an ideal gas (terrible approximation for this process) gives us a post-compression pressure of ≈ 45 PPa (you read that right: Peta-pascal) or 450 Gbar, and a temperature of roughly 650 000 K.

    These conditions are definitely in the range where fusion might be possible (see: solar conditions). So to the people saying you are only “trying to science”, I would say I agree with your initial assessment.

    I’m on my phone now, but I can run the numbers using something more accurate than ideal gas when I get my computer. However, this is so extreme that I don’t really think it will change anything.

    Edit: We’ll just look at how densely packed the monolayer is. Our cylindrical person has an area of 1.58 m^2, which, assuming an optimally packed monolayer gives us about 48 micro Å^2 per particle, or an average inter-particle distance of about 3.9 milli Å. For reference, that means the average distance between molecules is about 0.1 % of the diameter of the molecules (roughly 3 Å) I think we can safely say that fusion is a possible or even likely outcome of this procedure.



  • To be fair: If you live in the south, it doesn’t make much sense, but if you live a bit further north it’s the difference between getting up when the sun is a a reasonable place, or getting up in the middle of the night (winter) or the middle of the day (summer). I want it to be light out when I’m awake, not when it’s sleeping time.

    Turns out it’s easier to adjust the clock than to say “work starts at 9 in the winter and at 8 in the summer”



  • Some languages - specifically Norwegian that I know of, don’t have separate words for “boyfriend” and “girlfriend”. In Norwegian we have the word “kjæreste” which can be directly translated to “dearest”. To me it always feels a little weird to use “boyfriend” or “girlfriend”, i guess the same could be true for other non-native english speakers.






  • I definitely agree that breaking best practices in a way that could lead to UB or hard-to-find bugs should give point deduction. The sole requirement shouldn’t be “write standard compliant code”.

    However, a test does not simulate a real-world development environment, where you will have time to look through your code with fresh eyes the next day, and maybe even have someone review your code. The only thing a test reasonably simulates is your ability to solve the “thinking” part of the problem on your own. Thus, deducting points for trivial stuff that would 10/10 times be caught, either by the compiler, the developer or the reviewer, but isn’t “strictly correct” just seems pedantic to me.

    To be fair, other than the example by OP I have a hard time coming up with things that wouldn’t be either caught by the compiler or are very bad practice (which should give point deduction).



  • I have a masters degree in materials chemistry and engineering. When people find that out they often say stuff like “I could never understand that” or similar.

    I am of the firm belief that I could teach anyone everything I know given enough time and motivation. The thing is, I don’t think there’s anything special about me that makes me capable of doing what I do, other than thinking chemistry is extremely interesting. I don’t have a more capable brain or anything. I’m just a bit of a nerd.

    I absolutely agree that way too many people have the misconception that you have to be “special” to do a lot of the things many people find hard. It’s all about being interested enough to spend time learning it.
