Someone in my family who's in eight grade is looking to do a science project for school, I think it's a science fair type thing. It was a partner thing, but he's autistic so no one would partner with him. Any cool /sci/ approved stuff you can do at home? He is autistic but he's very well behaved and concentrates well and his father can help him.

ITT: science and reason are bad mkay
I sincerely hope you're not implying that atheism is either scientific or reasonable.
Sup /sci/ retard here
Someone posted this and I never went to college
Can any of you explain what it is?
Vector flow fields. They are a graphics system that is used to indicate the flow of both mechanical and EM waves. The angle and length of the tiny arrows indicate the direction and the strength of the flow. This can either be used to simulate wind, or water or magnetic attraction and many other things.
Looks ugly as fuck. That giant ring doesn't actually exist.
The answer to everything is love.
Is it true that the concept of "species" loses its meaning when taking time into account?
How does it lose its meaning? Life is continuously evolving so how species are defined could be said to be based on snapshot frames of reference. But even if you could view a continuous timeline of the history and future of life speciation would still exist. There would just be blurred lines at transitions between ancestor and descendant.
I'm planning on doing comp science next year but I don't k ow much about maths, what should I do before I go to study it at uni, finish the algebra?
Or should I study mechanical engineering instead
To the limit.
Welcome. To. The. Danger zone.
The object of your desire. The origin of your edgiest buzz.
To the limit. Take it to the limit.
Once I was shy, I was shy like you.
But But But But.
The limit. It is in sight.
If you're deserving of it or not - this doesn't matter now. I don't know why it's such a big deal, really. Take the crown.
My fellow /sci/ bots. Fit it in like only a true dog could. You need all limits. Close it like a Cartesian. Internal to you, you'll find all the function spaces...

hey guys im wondering whats the answer for (1-4i)z=10+11i if i need z's imaginary part?
it was on my exam but i dont know how to do it, can you help me brah?
are there any home lab crispr starter kits on sale yet?
Many studies show the benefits of taking vitamins supplements. However many others studies advocate that vitamins supplements are not necessary. Extra points for thoughts on fish-oil supplements.

is it possible to stay on this self taught computer science route and one day,(10 years or so) become an astronaut?
Let's assume I have a relatively large sample (500) from an unknown distribution. I can calculate sample mean and variance, can I calculate confidence intervals for them? I've googled and found that because of the central limit theorem it should somehow work out for the mean (what distribution would I use in the formula tho? Normal? T?)
What about variance?
Also stats thread or whatever.
Relax, if I understood everything I've read I wouldn't post here, would I? I'm shit at stats (and don't really understand confidence intervals), so I was hoping someone could explain this to me. Clearly, you're not the person for the job?
>In probability theory, the central limit theorem (CLT) states that, given certain conditions, the arithmetic mean of a sufficiently large number of iterates of independent random variables, each with a well-defined expected value and well-defined variance, will be approximately normally distributed, regardless of the underlying distribution
Okay, so how does that answer my question? From this I can learn that the average value is approximately normal if I have a large enough sample. Is that sufficient enough reason to use the z table? What about variance/standard deviation?
What were the biggest downfalls of the Saturn V? What could we do better today?
How much more efficient would a Saturn V be using today's technology?
>What could we do better today?
How about near-complete reusability?
>How much more efficient would a Saturn V be using today's technology?
Not as efficient. There are better designs that work far better. And they use space shuttle solid rocket engines (and main booster engines that are closely modeled after the F1 engines on the Saturn V).
First day of Data Structures:
Before class, there is a dude in front row with a mechanical keyboard on hacker typer.
Pop quiz at end of class,
1. Declare a 10 integer array called fluffy.
2. Declare a pointer to the 3rd element in fluffy.
3. Create a for loop that prints each odd number between 27 and 63.
4. Declare a filestream object for reading a file "data.txt"
Afterwards, professor asks who thought to themselves "What did I get myself into?", only people raising their hand are the 6-7 somewhat attractive...
