Would like to learn relativity theory

I'am 27 now and i have a burning desire to study math and physics from the ground up and I strongly prefer doing a self study.I want to be a self tutor till i reach certain level.My question is what is the minimum knowledge needed to read and completely understand the General and Special Theory of Relativity.As of now my level of math knowledge is basic differential calculus.I also have a basic...

Symmetry of graphs

Please help me prove that if a graph is symmetric with respect to the x-axis and to the y-axis,then it is symmetric with respect to the origin. I tried to post this in math stack exchange and it gives me an error "your question does not meet our quality standards" even though i was descriptive and i have seen this error many times.

Hyperbolic sine of x

Hyperbolic sine of x, sinh x= (e^x −e^−x)/2 What method do i use to prove this? Can someone prove this for me?i tried to post the same in math.stackexchange but it won't accept for some reason

Congragulations again.I'am a beginner c programmer and i don't intend to learn anything other than c and c++.I'am crazy about low level coding like firmware and device driver development.If i was in your shoes i would go for the other one,no matter the pay is low.[not that i'am rich!!]

yes i now have an quintic equation.now i can use any method to solve for 'x'. thank you

Working for defence companies

has anyone come accross posts within HN or else where that talked about questions asked when facing interview's for defence companies . i recently read a post in HN who had given valuable insights on how to handle interview's willing to work for defence contractors(but couldn't find it)

too good..i've added it to my favorites.
abstraction of...ya go on i realy want to know what's beneath that if there is. would be very happy if you could recommend a book which goes so deep.(deeper then that preferebly!!)

Reading euclid's elements

i've already mentioned that i have a burning desire to learn math from the ground up in my previous posts. to completely understand geometry is it worth reading ALL VOLUMES OF EUCLIDS ELEMENTS? if so how do you go about it?also suggest other excellent books on geometry.

no this isn't stupid.
Re:Ask HN:properties of real numbers on Friday October 15, 2010 @05:06AM (#1794024)
i know even i used to hate formal proofs!!!i assumed this might have a formal proof by not knowing that this property is based on informal reasoning. (but i personally like formal proofs!!!!!)
Re:Ask HN:properties of real numbers on Friday October 15, 2010 @04:58AM (#1794011)
oh ya..that looks like a formal proof!!!!!!!!!
Re:Ask HN:properties of real numbers on Friday October 15, 2010 @04:40AM (#1793987)
well..this gives the definition of real numbers http://en.wikipedia.org/wiki/Real_numbers..but doesn't mention even a single bit about the truthfullness of the properties of realnumbers.(to be honest i'am not in a position to come out with a rational explanation!!!!!)

Ask HN:properties of real numbers

Hello, The addition property of real numbers says if a=b,c=d then a+c=b+d.can someone tell me why is it true? is there an algebraic proof for this or should we accept this as being true based on inductive reasoning?i really tried doing a google search for a proof but couldn't find any. (i know i had asked a similer question a couple of days ago but i feel i might get a much more reasonable...

Ask HN:Math Books

Hello HN,I recently finshed reading stroud's and john bird's engineering mathematics.but i want to continue to read as much as math books possible.(not sure what the motive is!!) I'am really curious to know your personal list .Please list a whole bunch of math books that you've read and interested in. it's ok to list right from elementary to the most advanced mathematics under the sun.(also...

Re:Ask HN:Transitivity property of real numbers on Thursday September 30, 2010 @04:45AM (#1742675)
ah.that's a wise explanation .i even realised that it's just a fundamental law and not a theorem.anyways you made it clear.
Re:Ask HN:Transitivity property of real numbers on Thursday September 30, 2010 @04:21AM (#1742631)
ya you may be right...let me do some research on real numbers and it's properties and then get back to you!!!!

Ask HN:Transitivity property of real numbers

Hello HN,The transitivity property of real numbers says if a>b,b>c then a>c.but when i test this property with real numbers it give's me false results.let a=1,b=2 and c=3 then the transitivity property says if 1>2,2>3 then 1>3 which doesn't make any sense.i'll be glad if someone could comeout with a nice explanation.

Re:How to get a job at Google, interview questions & process on Tuesday September 14, 2010 @05:02PM (#1692306)
i'am sick of hearing google's interview process.a company like google with kickass problem solvers should not hire a person based on his fucked up SAT scores{to me it sounds like sad scores!!} it has to be purely based on talent,his aptitude/attitude and skills.

ok people ..can someone tell me what is that circular "thing" that surrounds the aircraft as the plane crosses the sound barrier? is that moisture or something? if yes how does it occur? an explanation on this would would really fulfill my curiosity.
