What’s a fact you like to share about taxonomy/phylogenetics?
I like to tell people that otter shrews are neither otters nor shrews, and are instead afrotherians, making them related to elephants and manatees.
What and why is the converging point for this equation?
EDIT: This appears to be a problem I'm just not going to learn the math behind for like 3 years. Thanks for the explanations!
1-(((n-1)/n)^n). It seems to converge somewhere around 0.6321, but I can't figure out why.
Background/explanation for those who want it:
I read a book back in 3rd grade about probability and one of the problems that stuck with me most was that the chance of rolling at least one 6 on a die if you roll it three times is 91/216: just 1-(5/6)^3.
Then the idea popped into my head: "If you have something with a 1/n chance, and you try for it n times, what's the chance you'll get at least one?" I found a website that helped with that (thank you djskal), and noticed that as I raised n, the chance got closer to 63.21%. I wasn't sure what to make of this, and just kept it as a tidbit for a few years, but today I made an entire spreadsheet to try and figure out the exact converging rate. The exact decimal goes down as n gets higher, but I can't find a pattern as to the rate at which it declines and as such where it would end. Any and all help with this explanation is welcome.
Slime really can't be that expensive...
So we've seen a few times that slime is super expensive because mobs are rare, but are we forgetting that trial chambers, yk, exist? They bypass the mob cap and give a giant supply of slime.
Are you born with your sexuality/gender identity?
I've heard this a lot in multiple places, that you are born with your sexuality or gender identity, and that's one of the reasons why "conversion therapy" doesn't work, but I'm a little confused on it. It mainly boils down to this: I see those as preferences, opinions, things that make you happy, etc., and all of those factors can change over the course of your life. Your preferred foods can change, your opinions on subjects can change, things that make you joyous one time can make you feel sad another. I don't mean for this to be invalidating or anything, I'm just trying to understand what the statement means.
Edit: "conversion therapy" is bullshit and basically torture. I'm not trying to justify it in any way.
Any tips for breaking gendering habits?
My friend recently came out as trans and uses she/her pronouns now. I'm very happy for her but I'm having a very tough time with forgetting and accidentally using he/him pronouns. It's not as much of a problem when I'm with her, since I've more actively focused on trying to break the habit, but in passing conversation especially I find myself often misgendering her (ex. "Yeah, I told him we should meet up sometime"). I feel bad about this every time I notice it, because I don't want to come across as unaccepting or mean. Do yall have any tips or tricks on how you're able to break misgendering habits?
