Any idea to add Internet to a micro rp2040 ( bluetooth if able ). All debugging ports have been used plus a GP4.

Just visit my “supa technical” Calculator thread right now!

UH- idk any of this stuff

Yes.

LabelOS is a cloud project i'm working on, go check it out!
It's here:
https://scratch-mit-edu.ezproxy.canberra.edu.au/projects/749672725/
Also there is a BUNCH of filler on my profile, i'm basically just taking a really long break from making complicated projects.
I'll still be updating a few though!
also, [@coolcoder1213] makes good projects, check them out!

it’s apparently measured in seconds and is basically thrust * time / propellant weight
I understand now and have understood it since late August. The measured force as mass back then, so they wrote impulse as mass*time and therefore specific impulse as mass*time/mass=time

G’day, people. I’m @Zebcat. I like frogs, science, and mathematics. After all, a large handful of my projects are about science/mathematics. Of course, though, my profile is majorly populated by meme projects that serve no other purpose but to further devolve modern humor.

“Yeah! STEM is a really cool ‘subject’, and it is actually been taught in my school!
Here's something which I guess is about STEM:
Graphene is an amazing substance. It is only 1 atom thick, and is considered to be (one of) the only 2D object(s)! This is so called an allotrope of Carbon, which I found pretty interesting. The people who discovered it in around 2004 won a Nobel Prize in 2010. They did it using a surprisingly simple procedure: stick a piece of tape on some graphite, pull the tape off, and then stick the tape together in half, repeat the process until you got a (still visible) 1 layer of Carbon atoms! This is graphene. Graphene's structure is composed of connected hexagonal-shaped Carbon rings, similar to some other substances. Graphene is really elastic, and has extremely high hardness (you won't believe, but it's even harder than diamonds!), is a really good conductor of electricity, (kind of) transparent, and extremely light! All of these useful properties make graphene may have some important uses, and will be a huge step in technology.
Graphene isn't used much for right now, except for some special research purposes, however they do have a lot of potential uses! Space elevators may now become true with this single-atom thick allotrope of Carbon. Phones that can bend may be sold in the market, touch screens are now more easy to use, armors and shields now are way harder, … Graphene may even solve the water crisis of the world! Scientists have looked at the properties of graphene that may extract pure water from seawater easily, using some techniques within the process.
Also, I'm looking for substitudes for plastic (like bio-degradable plastic). Because of its flexibility, it could potentially be suitable to make ‘graphene bags’ from it, and perhaps it could even solve the world's plastic problem! I'm not sure about this, but it could be a good guess.
I hope that's an interesting topic, I spent like half an hour writing this! ”
I also heard that there are many formations of carbon that take on interesting properties. One such formation is called a bucky ball. It is a carbon formation of a ball and may be used to store fuel, similar to the protein ferritin in eukaryotes that stores iron.
wait a minute it looks 2d but paper is technically not 2d its height is just super short or am I wrong

Would you say? “0” is basically the inverse of infinity, and yet every finite, however large, is still 0% of infinity. In that way, nothing is truly “close” to infinity. Would the same not apply to 0?

Shadows are the absence of light. They practically don’t even exist. You just see them as less light, something that actually exists.

Also, I'm looking for substitudes for plastic (like bio-degradable plastic). Because of its flexibility, it could potentially be suitable to make ‘graphene bags’ from it, and perhaps it could even solve the world's plastic problem! I'm not sure about this, but it could be a good guess.
I hope that's an interesting topic, I spent like half an hour writing this! ”
I also heard that there are many formations of carbon that take on interesting properties. One such formation is called a bucky ball. It is a carbon formation of a ball and may be used to store fuel, similar to the protein ferritin in eukaryotes that stores iron.
wait a minute it looks 2d but paper is technically not 2d its height is just super short or am I wrong
Nothing is 2D lmao
well they call it 2d because it’s just super close to 2d tho
Would you say? “0” is basically the inverse of infinity, and yet every finite, however large, is still 0% of infinity. In that way, nothing is truly “close” to infinity. Would the same not apply to 0?
well, in real life, even 2d materials have thermal viberations, so yeah, they aren’t really 2d, but they’re SO close (closer than paper) to 2d that it’s safe to call them 2d
but shadows are 2d
no. they take up 3d volume, but you don’t see that without smoke
oh

I. LOVE. SCIENCE
I love animals

According to that equation you just showed, it should not be measured in seconds.
For whatever reason, folks back then wrote force as mass (as in force due to weight), so it would be written as mass * time / mass = time. This weird convention has stuck around.

G’day, people. I’m @Zebcat. I like frogs, science, and mathematics. After all, a large handful of my projects are about science/mathematics. Of course, though, my profile is majorly populated by meme projects that serve no other purpose but to further devolve modern humor.

Masses of 2 different bodies right? What is this for?

Specific impulse. The first mass in “mass * time” ACTUALLY means thrust (and thrust * time = momentum). For some reason the folks from whom specific impulse became widely used used the same units for force as they did mass.
