Welcome to c/science_memes @ Mander.xyz!
A place for majestic STEMLORD peacocking, as well as memes about the realities of working in a lab.
Rules
- Don't throw mud. Behave like an intellectual and remember the human.
- Keep it rooted (on topic).
- No spam.
- Infographics welcome, get schooled.
This is a science community. We use the Dawkins definition of meme.

Student in my physics class: 'How much energy does it take to kill a person?'
'Ok, assuming falling from 25 meters results in 100% death rate...'
Morbid I know...
Well, first you need to define a "person".
Then you need to define the starting point and what all environmental features you are considering as zero cost.
Otherwise, to calculate energy to kill a person, you need to start by creating the universe.
On the other hand, for a human person, you can either just get a really big syringe and siphon out blood from the heart, or pierce a thin little metal pipe with tactically placed holes, which will let gravity and internal blood pressure do the job. But these require access to a syringe/metal pipe making setup, which has its own energy costs.
I have never seen anyone un-upvote their own post before on this platform (viewing from voyager at least), most of my comments are initiated as pre-upvoted by myself, the author.
I’m thinking either you did undo the auto-upvote, or the other possibility is that it posted with zero votes for some reason. I might have to start also de-voting my own posts that I am not specifically enthused by or excited about, if that is what you have done here.
(I’m still on Reddit mode where there might be some kind of running total for my profile, but I never bothered keeping track or angling for extra votes over there much either, it just cracks me up how much the little sorting algorithm metrics mean to some of us even when we might not be willing to admit or even recognize it sometimes)
I initially started de-upvoting just because it felt weird to have a blue marker on my own comment, which was supposed to be for other's comments that I upvoted. It then evolved into having a "reason" behind it. But yeah, it just seems weird to upvote one's own comment.
