I need moral guidance.
A friend of mine gave me a small maths puzzle, telling me it was "kind of tricky, took me about half a day"
That was 2 days ago, I have 1 more day until i see him again and I havent solved it yet. Obviously i will keep trying but i am not very smart and i dont hold out much hope of figuring it out.
Do I
1) be honest and tell him I couldnt do it and have him think less of me
2) Google the answer
3) Try and get a hint from some other friend
4) skip out on some of my studying to really devote a lot of time to it and hopefully crack it eventually
What do you think?

That's a rather subtle way to get us to solve your homework.

>>7789187
not really considering im not going to post the question
it will get solved in <10s and thus ruin the puzzle for me

Be honest, show him what work you have, have him guide you through the rest of the process. He likely wasn't doing this to trick you...probably just wanted to share his passion with a kindred spirit.

Would it be safe to assume that any string of integers will appear as consecutive digits of pi?

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.

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.

Is it true that the concept of "species" loses its meaning when taking time into account?
3 Posts / 1 Images

Species are just a social construct.
>>
>>7788944
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
Please help

Honestly get on khan Academy and do all the algebra. Master Algebra. A strong foundation of fundamentals is the best thing you can do without overwhelming yourself.

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 you need. Believe in yourself. I'm here to give you this completion. You don't need more spaces, it's all there. to [math]\infty [/math] and beyond, everything is connected, really. You can map it to all your dreams. All of them. Implement it - you can have it constructive if you feel like it. It's like sex, except you actually can have it. Now. Thin and with power objects.
Rewrite your life now. It has the Rosser properties you want. You're the primadonna of efficiency.
Don't scare away. Not now. Now. The time is now. 2016. It all began here. Save the date.

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.

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?
Pls help?
Also stats thread or whatever.

kek.
I think you misunderstand the meaning of the CLT.
>>
>>7788853
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?

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).
