My favourite thing about groups is the generic name for the operator is blob.
They are sets not necessarily groups. A set is just a collection of elements a group is a set which has to strike some criteria which I can't fully remember but as you said identity, inverse and...
R is reals, Q is rastionals, R/Q is reals not including rationals i.e. irrationals.
No, N is countable in literally the exact meaning of the word. Whereas with sets like R it's literally imposisble to count all the elements.
The words that probably aren't the best are words like...
Also if it's of any interest to you

Basically if something is countable you can essentially take every element in the set and say it's the same as 1, 2, 3 etc. The link I posted shows how you can do this for rational numbers.
There...
Thats' like 99.9% arbitrary as fuck and means nothing.
rational numbers are countable

irrational numbers are uncountable
cantors diaganol argument literally goes against what...
I don't follow. It says the countable numbers which are infinite you'd think would be so big everything could fit in there, ldo. Ohh shit look at all these things that don't fit in there because they...
When I read ongs post I thought to myself that definitely isn't what cantors diaganol argument proves. It may follow on from it but it's not obvious (in my simple mind) how it follows. So I looked at...
A school isn't going to buy used lab equipment off a stoner.
Can you wait till they finish/cancel better call saul?
Too late, dead to me.
Yeah it's 100% me wanting something for nothing. I don't disagree. I'm like ohh I'd like to half ass learning physics and it cost me nothing, I'm entitled bro.
I should check out my uni library...
All those books are like £50+. Which isn't much but it really puts me off. At teh same time stats and probability is probably (or maybe I'm misunderstanding) my weakest part as I never really did any.
Overpriced ice cream.
Birthday isn't till August.

Physics, everything else isn't science.
I love you and your enthusiasm for science. Thank you for the suggestions. I want to get more into particle physics. I'm having a slight crisis in life that...
MMM I want to get into science.
Any suggestions on books to read? I'm thinking 1/2nd year undergrad stuff would be the right level or very interesting more general public books if you have any...
People rarely appreciate genius during it's time. I imagine people will look back 1000 years on at these forums and appreciate the real insight it gave into a genius breaking down his thought...
I should mention that I absolutely hate 99% of numberphile videos for this exact reason they go from casual talking about a problem, some simple solution, ????, final answer and you're meant to take...
The theta comes from eulars formula
e^(ix) = cos(x) + isin(x)
Which isn't actually an angle in terms of the problem itself it's just a byproduct of solving some part of the equation linking it...
After thinking I've found what you're talking about I completely agree variables come out of nowhere and aren't defined, the bigger version of his worksheet is very hard to follow and I'm sure there...
I watched that numpherphile video thinking I could get involved with what you were talking about only to find out that you were talking about something completely different, fml.
Clue me in as to...
There is no such thing as a perfect vacuum. You are correct in what you say.
Even if there are no particles there energy is enough to make matter so yeah vacuums don't exist.
