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.

I'm too dumb for maths because I have dyscalculia, but i am always amazed by the engineering crowd on how they could improve efficiency by finding and tweaking just the little things.
Its simple rocket math. Every lb of weight must consume fuel.
Si.pky. 1 lb of weight needs 1 lb of fuel to escape orbit. But the fuel has weight also. So the effective fuel you need to lift the rocket and payload is exponential.
The harder stuff is orbital mechanics. Getting things into orbit is easy. Having thwm go where you want is the hard part.
The tyranny of the rocket equation. Generally, 1% of weight is payload, 85% is fuel.

Good article for pointing out that specific rocket math. The optimistic tone of that article, though, is very much a product of its publication date of February 2020. The space programs have suffered major technical, financial, and political setbacks since then, and the geopolitical moment doesn't really lend itself to megaprojects like moon missions.
The sooner humans can move past rocket tech the better to be honest.
Stop living in a gravity well and we wouldn't have to expend energy to get out of it!!
Til dyscalculia. I hope you weren't born in asia
I am Asian ๐ I refuse to live up to the stereotype!
Or expectations!
Or are you a doctor?
I won't go too specific but my background is in biotech.
So.. you're going to be a lawyer then?
I already work on STEM, without the E, but a little bit of M.
How are you doing m without being m?
It's regulatory requirement to use calculators in my field to make calculations, so that has been saving me.
