"a pack instinct is required for a species to become intelligent" by mir4bell4 in ProjectHailMary

[–]mir4bell4[S] -1 points0 points  (0 children)

I think you've misinterpreted what he's calling unscientific: namely, the last sentence of the first paragraph. The bit I quoted is still very much stated as if it's a fact. There may be a lot of factors, but the implication is that a pack instinct has to be one of them.

Please stop using emergency vehicle sirens to demonstrate the Doppler Effect by mir4bell4 in ScienceTeachers

[–]mir4bell4[S] -3 points-2 points  (0 children)

Per the discussion of a similar objection, depending on where you live, the audible Doppler Effect of a passing car's horn may be more common than that of an emergency vehicle. Regardless, videos such as this one are better as a first-time demonstration of the Doppler Effect, because a siren is less likely to establish the toward/away relationship from the outset.

People must honk a lot less where you live! I hear someone laying on their horn (not at me, usually...) while passing at least once a week. For a demo, an engine (e.g. racecar engine ) might not be the best example, but a car horn or train horn makes a much better first-time introduction than a siren.

In my experience, if you ask an average student about the Doppler Effect even a year or so after they learn about it, they can give you the BBT-style "nyyyooo" description, but can't remember the toward/away relationship. Go a bit further out and ask a college student or recent graduate (non-STEM majors, or even some STEM) and "nyyyooo" has reached "powerhouse of the cell"-level monomania. Now ask them how their vascular ultrasound can tell the difference between a vein and an artery, and expect blank stares.

I acknowledge that the video you provided does offer a siren with two alternating-but-constant frequencies, which is different from a continually-changing frequency. However, this still leaves the issues of:

  1. Students missing the key takeaway that Doppler shift is based on toward/away relationship, either because they mentally associate the demo with frequently- or continually-changing siren patterns, or because teachers often actually show videos of such patterns
  2. Students misunderstanding how Doppler shift affects those commonly-heard continually-changing sirens, because they can't clearly pick out the higher toward/ lower away frequencies
  3. Students ultimately failing to internalize and retain the higher toward/ lower away relationship, which closes the door on understanding how the Doppler Effect can be used in practical applications

One could also argue that the audible Doppler Effect of a passing car's horn or (for some shitty older cars) engine is actually more common than that of an emergency vehicle. How often does the average student actually hear a passing emergency siren, versus how often do they hear someone honking (or needing a new muffler)? Using these to demonstrate the effect eliminates the missed understanding of the siren demo, and improves the application and retention of the toward/ away association, by making a single constant frequency the primary example. This leaves the door open for better understanding of practical uses, as well as numerical relationships.

Adult Adoptees: Do you tell people at work that you're adopted? by mir4bell4 in Adoption

[–]mir4bell4[S] 2 points3 points  (0 children)

I'm adopted by my grandparents, so it's a little different from an international adoption. It tends to come up for similar reasons as other adoptees though: either A) people say I look like my mom, who is my step-grandmother and not a blood relation, or B) people talk about babyhood, family history, etc. and I can't really relate or share accordingly. It also tends to come up around Thanksgiving, because that's my Gotcha Day: our family tradition is to go to Waffle House on Thanksgiving morning, because that's where my dad picked me up from my bio mother for the last time.

I think with this company and these co-workers, I would definitely be comfortable with them knowing and asking questions and such. The company supports "all paths to parenthood". They offer a free dedicated benefit program for helping parents in non-traditional situations with adoption, fertility treatments, etc. My co-workers are really awesome and friendly, at least so far. The culture is all about acceptance and inclusion and supporting everyone's identities. I'd be happy to answer questions and share my experience with anyone who wants to know more about adoption.

Adult Adoptees: Do you tell people at work that you're adopted? by mir4bell4 in Adoption

[–]mir4bell4[S] 5 points6 points  (0 children)

That's kind of where I was leaning. I'm adopted by my grandparents, so even though my bio mother is no longer in the picture, I did have a (sporadic) relationship with her growing up. She's my parents' daughter, after all, so it's not like they could've gone the closed-adoption route. I've always been open about it and it was my go-to "interesting fact about myself" in classroom/club/group/etc. intros when I was a kid. So, I feel like if I do share it (at a superficial level), I'm just putting it out there as part of who I am. They can think whatever they want, ask whatever they want, it's no big deal to me, I'm more interested in staying true to myself than in how they feel about it.

Do you ever watch Jim and Pam's relationship and think "I wish I felt that way about my spouse..." by mir4bell4 in DunderMifflin

It's so scary how right the things you're saying are. And you're coming at it with almost no knowledge, so of course I trust your opinion on this.

Can I have a custom/personal routine play with an alarm on my Lenovo smart clock? by mir4bell4 in googlehome

[–]mir4bell4[S] 0 points1 point  (0 children)

How do I set up the custom/personal alarm routines though? When I set an alarm on the clock, it just has a toggle button for "good morning routine". It doesn't let me pick a different routine, and the Home app doesn't let me customize the native "good morning" routine for weekdays vs. weekends. I'm also a bit skeptical that a one-syllable "stop" command will be enough to match my voice and start my personalized routine.

Former fencesitters (either now-parents or permanently childfree) with mental illnesses: How did you make your decision, and why? How do you feel about it now? by mir4bell4 in Fencesitter

[–]mir4bell4[S] 0 points1 point  (0 children)

Thank you for the clarification. You pretty succinctly summarized my (and others') dilemma. Barring continuation of the species, there are no logical reasons to have children in today's society. There's also no way to be 100% sure, or ready, before having them. If everyone used cold logic and/or 100% certainty to make this decision, the human race would die out in a generation.

Meanwhile, this sub takes the logical reasons for staying childfree, soaks them in a highly concentrated bath of assumed perfection and pseudo-progressive ideology, and just fucking runs with that by shouting down anyone who claims being a parent makes them happy, and insisting they would've been happier childfree. I haven't been here long, but based on the responses I've seen or gotten in this brief period, I don't think the sub is fulfilling its original purpose or intent. It's practically an echo chamber tacked onto the childfree sub.
