I FUCKING LOVE SCIENCE!!
I think its a neat fact. At the very least, the units are correct.
What is emptiness (as in, the space between matter) according to modern physics?

undeformed spacetime
>>7672795
It's the vector that belongs to the kernel of every symmetry generator of your theory.

Please explain congruence modulo to a retard. I read lots of explanations but I still don't get it. What's the intuition behind it?
>>7672770
Two numbers (a and b) are congruent by modulo n iff the remainder from dividing a by n is the same as the remainder from dividing b by n.
I find this way of thinking about it to be simpler, as then you can think about them as being the same distance from a multiple of n.
The other way of stating it is that two numbers are congruent by mod n if the distance between them (a-b) is divisible by n.
>>7672779
To give an example with this guys story:
a = 9
b= 18
Then a and b are congruent in modulo 9,
Because if you divide 9 by 9, your remainder is 0.
If you divide 18 by 9 your remainder is also 0.
I've never heard of the concept, but I just understood it by the name. Why is this so hard for you?

I get the definition, but I don't get:

Has anybody done their interview at Cambridge for Computer Science? I've got an interview soon and I'm wondering what are they gonna ask me, are there gonna be any tests?
Pls halp
18 plus board faggot
>>7672721
I am 18 you fucking homo. Most people who apply to Uni are.
>>7672722
Even if that stats that you pulled out your ass is true, homework threads are not allowed, so please leave you faggot.

Does anybody else here have a tendency to think that their research, publication and thesis ideas are crazy, dumb, or otherwise irrelevant?
Here's my story:
>have an idea in the domain of application of Artificial Neural Networks to some specific, rule-based type of problem solving
>ask my professor whether it's retarded, and his thoughts on the topic
>surprisingly, he says that it can work
>ask another one who's more reputable
>he says something along these lines as well
>he gets me in contact (via email) with a rather known professor who specializes in this topic
>ask her for her opinion etc., and whether my idea is nonsense
>she says that it's a novel approach, that I should try working more on my idea; she also recommended some literature to help me
However, even after getting a more or less positive feedback from others, I still think that my idea is crazy/retarded/etc.
Does /sci/ have any advice on having a more realistic view on one's research ideas? Has anybody else had problems undervaluing their ideas and themselves?
