not sure if DIY or Sci but here we go. How do I make rocket fuel. Liquid rocket fuel. I was thinking a alcohol + Hydrogen peroxide. How do I get the pure alcohol in order for the mixture to work?
Wikipedia says that its density is 0.9 kg/m^3
At sea level and at 15 °C, air has a density of approximately 1.225 kg/m^3
Am I missing something here or is this just Boeing PR fluff?
The metal lattice itself weights 0.9 kg/m3; they're not counting the air between the metal bits, since there's no closed pockets in it.
It's the same reason that when weighing, say, a gold ring, you don't also have to count the air encircled by the band.
Post your favourite things out of all the maths you know
you guys like Math? i need help with answering these homework questions on the AC Factoring method. if anybody is willing to give me the answers i will be most greatful.
For fuck's sake.
You are not asking for a hint, not even to have us solve one to give you an example of the general method, you are literally asking us to give you the answer.
Fuck you, anonymous poster with clearly no real appreciation for math and science. I hope you fucking fail.
Hey /sci/I'm about to present my thesis result to an academic jury and I have no idea how to esthetically present it...
Can you help me with some templates or any advice for it?
BTW my work is about alternative construction materials.
Use the template of you institution of they have one. Use powerpoint if you're not autistic, latex if you are. There are many fine templates in powerpoint, try some out, but keep it simple and readible. Don't put shitloads of text, rather use concise bullet points and diagrams. Tell your audience the topics you are going to discuss and in what order. After each topic show a list of which topics you have covered greyed out and pointing to the next topic you're going to discuss. Hope this helps.
Say a balloon skeleton had negligible mass and a perfectly rigid body, so that it couldn't be deformed in any way. If I vacuumed out all of the air, making the inside a perfect vacuum, would it float? If so, then how much could it pick up relative to its size?
Why are some people so skeptical of science or hesitant to believe conclusions drawn through scientific methods?
I tried to explain relativity to a friend recently and she told me it was strange and she had a hard time accepting it, to be fair it can be a bit strange, but here's the thing she believes in all kinds of /x/ things like demons and shit.
It really struck me how she could easily accept those things but relativity was too "strange".
Why is it that you can present a person with scientific models of how the world works, with evidence,...

People it more comforting that conscious forces are controlling things because they're easier to relate with.
Nothing is more terrifying than the realization that reality can't be reasoned with.
I had a dream that I was in school, turning in my physics homework and Elon Musk was my teacher. He had this face and said that he "really liked this" pointing to my equations and work.
I never really felt motivated to get my degree until that dream. Wow. I really want to just impress this guy. I think that would be one of my life goals.
You should tell him that
is science and autism the same thing?
If i was to boil piss until all the water evaporates, and then i boiled the sludge on the bottom, would it create phosphorus?
Can anyone explain or debunk this?
>move further from earth
>moon looks smaller faster than earth looks smaller because the moon itself is smaller
>move far enough to where the moon's silhouette is smaller than the earth's
>position the camera so the earth takes up the while image
There you go, you filthy fucking retard.

I need to know how I can use a convection hearting method for an idea I have.
I have an idea that'd heat up tortilla chips to a restaurant style hot experience....
...I tested my idea out by putting tortilla chips in my convection oven, and sure enough they tasted phenomenal, after putting them inside for 375 degrees Fahrenheit.
....So, how can I take that convection hearing technology and apply it to my picture?
A vaporizer exists that does it too:
You put the marijuana insid, press a button, and it heats up the bud so within 2 minutes you're ready to exhale
How can we do that with this idea?
Mine is basically about memorizing a bunch of information and do something with that...
And this happen specially in science & math.
I wonder if in other countries do the same.
It's a bunch of faggots expecting the same piece of paper everyone else gets to elevate them to a upper class pay check.
Their excessive complaining about overpaying and under performing degrees leads to watered down academics and a perpetuation of the first statement.
What should I look out for when I want to get a telescope? What kind do I need to be able to see saturn in a quality of pic related? Do I need a special one if I want to hook up my DSLR onto it, or will pretty much any one do?
You don't need a super powerful telescope to be able to see the planets up until you hit Uranus. Plants are generally the easiest thing to see in the sky right behind the moon and the sun.
Thank you, glad to hear that.
Should I go for a refractor or a reflector? Is getting a used higher model better than a new cheap model or is it not worth the risk / problems of a used one?
