  • It feels like I’m the rope in tug-of-war between my current career and my ambitions to become a physician.

    There’s the long term decision and the current reality of trying to passably perform in both work and my organic chemistry class.

    Is increasing trans representation in healthcare really a worthwhile personal pursuit with climate calamity on the horizon? Would it be better to channel my energy into mutual aid, community organizing, and foster care?

    I wish I had an academic mentor (or any mentor) to talk to about it. Yeah, I’m a real adult now and therapy is a thing but 🤷‍♂️



  • Your first sentence is incomprehensible to me.

    What I mean is that I logically it’s very good to have people who are passionate about honoring human respect and dignity. It’s more moral and closer to the kindest world we could have. A diversity of opinions is necessary and first, and foremost, I wanted to recognize and respect the good work of voicing a less popular opinion to uphold your virtues.

    Personally, I’m more worried about the collective pain and suffering that could be avoided if the status quo is maintained than quickly taking action and inadvertently breaking eggs. IMHO, the main reason sociopaths prevail is that empathetic folks waste time and effort trying to find a fantasy path where no one is hurt. Seems to me like the focus should be efficient and effective resolution of societal issues generating mass suffering period rather than having an Entmoot.

    We’re not going to be able to impress billionaires so much with kindness and consideration that they prioritize the greater good over short-term interests. Better is the enemy of done.

    My viewpoint is that we need to prioritize the reducing the most suffering yesterday. you don’t have to and probably shouldn’t agree. Discussion and disagreement are necessary for coalescing on a good path forward. Better ideas come out of a composite of values, flat personal opinions.

    Tl;dr - I think your ideals are good and right in an ideal world, but also think the sentiment has misplaced priorities in the nightmare unfolding with exponential consumption of resources and pollution of the planet. I’m grateful for the opportunity to discuss and this is a nice change of pace/tone from Reddit.



  • This is a good question! Not sure which precise units they had and in what quantity, but given the size of the Titan (no way they can support liquid regenerative system with their size and energy reserve constraints), they would have had canister containing solid CO2 adsorbent with a fan (example).

    Without the fan, it’s not going to be very effective since CO2 has to actually pass over the solid. Passive diffusion is not going to move the same volume of CO2 over the solid even if the solid was removed from the housing. Even if they didn’t run out of battery, The solid has a maximum capacity - about 7.5 kg for the unit linked above. Even with reserve capacity, an average human exhales ~0.97 kg of CO2 per day.

    O2 to CO2 exchange via respiration is mole for mole (you do lose a little mass in carbon and water just by breathing!). Atmospheric CO2 is 0.041% (410 ppm) and O2 is a hair under 21% and that’s the standard to which life support systems are held. Humans lose consciousness at around 3.7% oxygen, but experience hypercapnia at >6% CO2. (Physiology nerds - I converted from the partial pressures in mmHg to % of 1 atm for comprehension)

    So in this hypothetical scenario, hypercapnia would definitely precede loss of consciousness due to anoxia.







  • Not actually correct in this case. Hypoxia is only painless if oxygen is displaced with an inert gas like nitrogen. Our bodies detect low oxygen indirectly via chemoreceptors that detect the increase in blood acidity (respiratory acidosis) induced by high carbon dioxide (hypercapnia).

    As humans breathe in a sealed environment, oxygen is replaced with CO2. Hypercapnia is what causes the panic and pain of drowning prior to inhalation of water. Consciousness is lost mere seconds after water inhalation.

    Drowning and hypercapnic asphyxiation are essentially the same experience in terms of suffering.

    Secondary outcomes and resuscitation are a different story, but are obviously not applicable here.


  • Living within the bounds of common “social acceptability” is stifling and dull, in my personal experience. Being kind and considerate is important, but why waste precious time trying to suppress or conceal harmless parts of oneself?

    I’d rather select for settings where I can be embraced as my authentic self. I was forced to live with someone who was harshly judgmental and crapped on facets of me daily when I was growing up. I’d NEVER willingly subject myself to that again.





  • Things are hard right now. Father’s Day is always rough. Taking summer term organic chemistry while working full-time is more than I can manage well. It doesn’t help that I sped through gen chem 2 in 6 weeks just prior to this.

    I’m super burnt out and I don’t have a lot to show for the past sprint at work plus my first midterm is on Friday. This weekend was supposed to be productive but my brain has been on strike.

    I did get some exercise in today and it did help a little but I’m nowhere near the capacity required.

    I’m very grateful for my life and opportunities afforded to me and I really shouldn’t be complaining about relative non-issues but 🤷‍♂️
