>I'm new to most scientific concepts
I never studied science past secondary school, it's just something I try and teach myself in the little spare time I have

Thank you for the reference! I will try wrap my head around it

Hey /sci/

TL:DR, your theories on the double slit experiment and wave-particle duality in general?

Please bare with me, I'm an enthusiast at best and I'm new to most scientific concepts

I definitely don't understand it as good as you guys, I just finished watching Feymans lecture on the double slit experiment (https://www.youtube.com/watch?v=hUJfjRoxCbk).). It's my understanding that the photons acted like waves only when being observed, and acted like particles when left to hit the detector unobserved. My questions / thoughts:

>Do the photons start life as particles, and assume the form of a wave during interaction or vice versa
>Are the photons interacting with themselves, or just simply whatever apparatus is used for monitoring them mid flow

I'll think of some more questions if this is something anyone would like to discuss

The math fruit?

>>5653634
What I think I want to avoid is crashes, so sugar might be a bit of a risk. But caffeine on the other hand is a great idea!

>>5653626
Just realized apples are a big no-no on exams.
But bananas - any fruit apart from these delicious yellow beings that are godly?

>>5653623
Fruits
>Bananas
>Apples
Any superfruit apart from the regular?

>>5653615
Well that was a misfortune.

Also, I prefer alot of pasta the night before a big exam.

Wow, that's amazing, thanks people!

Hey /sci/, I'm taking up basic math and physics again after being out of school for some time. A question I've asked myself for a long time though, and I can't answer with my limited knowledge is: Can thrust be made in vacuum, with the power of electricity? I'm thinking space crafts, they can't carry that much fuel to burn and have to use it very conservatively. Though solar panels can create electricity and heat people and give life to all equipment, I can't think of a way to use the electricity to propel the vehicle.

Is it impossible, really hard, of am I completely retarded for not knowing the answer?

Pic somewhat, unscientifically, related.

At least someone knows their shit. Thanks.

No shit sherlock. I need numbers.

>>5402245
If you want to actually be good at math, then you kind of have to.
>>5402249
They tend to be shit.
I was hoping to start a discussion about it, but it looks like /sci/ is no longer about science and maths.

>>5402224
Does it shock you that someone would dare post a thread of relation to mathematics on the science and maths board?

Warning: Statements about books I haven't looked at in a couple of years may be factually incorrect; please forgive my spotty memory. I don't think I have any really egregious falsehoods in here. I apologize for the appearance of this page; most web browsers have not yet been updated to handle the HTML4 entity set, so fools like me who read the definition write ugly-looking pages.

Enough apologia. Here we go:

>Chicago undergraduate mathematics bibliography

Somehow I became the canonical undergraduate source for bibliographical references, so I thought I would leave a list behind before I graduated. I list the books I have found useful in my wanderings through mathematics (in a few cases, those I found especially unuseful), and give short descriptions and comparisons within each category. I hope that this list may serve as a useful “road map” to other undergraduates picking their way through Eckhart Library. In the end, of course, you must explore on your own; but the list may save you a few days wasted reading books at the wrong level or with the wrong emphasis.

The list is biased in two senses. One, it is light on foundations and applied areas, and heavy (especially in the advanced section) on geometry and topology; this is a consequence of my interests. I welcome additions from people interested in other fields. Two, and more seriously, I am an honors-track student and the list reflects that. I don't list any “regular” analysis or algebra texts, for instance, because I really dislike the ones I've seen. If you are a 203 student looking for an alternative to the awful pink book (Marsden/Hoffman), you will find a few here; they are all much clearer, better books, but none are nearly as gentle. I know that banging one's head against a more difficult text is not a realistic option for most students in this position. On the other hand, reading mathematics can't be taught, and it has to be learned sometime. Maybe it's better to get used to frustration as a way of life sooner, rather than later. I don't know.

Reviews not marked with initials, or marked with [CJ], were written by me, Chris Jeris ('98). Other contributors are marked: [PC], Pete Clark ('98); [PS], Pete Storm ('98); [BB], Ben Blander ('98); [RV], Rebecca Virnig ('00); [BR], Ben Recht ('00); [MG], Marci Gambrell ('99); [YU], Yuka Umemoto ('97). Thanks to all of them for their input.

>>5402129
Yes.
That's called a bibliography, Tommy.
This particular bibliography is devoted to good books on mathematics, as you can see.
Since /sci/ is full of undergrads and teenagers, I thought this might be useful for them.

I'm awake.
So have any of you seen that link yet? What do you guys think?

>>5401316
Brb, going to bed

>>5053765
This is the general idea I suppose.

>>5053796
With the internet and libraries, I can hardly say I've been isolated from anything significant.

>>5053800
Hah, no. It is not entirely different from string theory in concept, but isn't at all similar when you get down to the math involved.

>>5053809
I hardly care if I'm dismissed as a crackpot on an imageboard.

>>5053808
I wish it contained less. I am currently at a sort of mathematical boundary of sorts.

Hey /sci/
I'm playing a game with some friends. I could use dome really difficult math riddles/questions.
Answers are nice as well so they can check their work.
Thanks guys.
Pic unrelated.

"One fourth of Americans are retarded."
http://www.southparkstudios.com/full-episodes/s10e09-mystery-of-the-urinal-deuce

There comes a time in life where everything seems narrow. Choices have been made. I can only continue on. I know myself like the back of my hand. I can predict my every reaction. My life has been cast in cement with airbags and seatbelts. I've done everything to reach this point and now that I'm here, I'm fucking bored. The hardest thing is knowing whether I'm still alive.

>>4628884
Can someone give an explanation? Yes, I'm retarded.
>>4628879
Yes, I'm retarded, but not that much. Zero IS a number.
