How do people who take academia seriously avoid defining their selves by their academic performance? I take my grades very seriously and I tend to get extremely depressed whenever I do poorly on an exam or get below an A in a course. While other people are out socializing, developing hobbies and personalities, I am studying textbooks and I feel underdeveloped as a result.

Minimum achievable temperature. Is it possible to prove that a specific temperature is impossible to achieve for a given system? Would the minimum temperature be given by planck's constant divided by boltzman constant?

Temperature = agitation

No agitation = minimum achievable temperature

But the smallest amount of allowed energy is given by planck's constant right? So what would it mean for the energy spacing to be less than this. For example I have found the energy spacing for a particle in a 3d box to be on the order of 10^-42 for states near the ground state.

I have a theory that I want to discuss. What If in a not so distant future Where AI is a thing and we learn ”it” to program. Then we’d give it instructions to program and design a viritual world and design close to perfect VR technology. What if we then were to make chairs with feeding/drinking automatic and unnoticable. How many people would leave this world for their own private world, made just according to their requests? Would you Do it?

what is the rate at which my adenosine receptors come back after not drinking coffee?

I used to drink 6 cups a day on average, I had a cup last saturday and haven't had any caffeine at all since then

what percent of my adenosine receptors came back / how much tolerance for coffee have I lost?

>> No.9683286

I find that if I go around 2 weeks without any coffee my tolerance drops back to baseline, or near enough. Why are you drinking that much coffee? If you're becoming exhausted during the day you should probably start searching for the underlying cause instead of covering it up with a stimulant. Not that coffee is bad, but it's obviously preferable to just fix the underlying issue.

>> No.9683334

>>9683278
>6 cups
That's pathetic. If you need a stimulant that bad then just get yourself an Adderall prescription

>> No.9683410

>>9683278
If you need that much coffee per day then you might have developed caffeine sensitivity. If you feel tired after drinking, say 2 cups of coffee, and you drink more to compensate for your increased tiredness then you might have caffeine sensitivity. More isn't always better, try to drink just 1 cup of coffee and see if that helps.

Hear me out here:
A recent study showed that your DNA actually changes with the passing of the seasons.
https://www.nature.com/articles/ncomms8000
Given that, could it be that these seasonal changes affect the development of a woman's child while she's pregnant? There has been studies showing that many personality traits can be determined largely by your DNA. In fact, this plays a larger role in your eventual personality than how you're raised.
This can be easily observed in other animals. Many dog breeds have their own temperament. Saint Bernards are big, lovable oafs, lhasa apsos are aggressive assholes, and so on. It would be easy to assume that other animals have personalities determined by genes.
So if your DNA changes throughout the seasons, and if these changes could affect the development of your child...
Astrology has a bit of truth to it. If your baby is developed under x conditions, and x conditions tend to arise at different times of the year, and x conditions affect the development of your baby, then at least the "if you're born on y date" part has some truth to it. The rest is total bullshit, however.
Thoughts?
