@JohnRennie I'm really sorry...something came up and I had to go offline for few days...I'm sorry it's not gonna happen again....so...few days back I asked for ur help on what to study if I'm interested in physics.....could you please just help me........I have Griffith's intro to qmech,electrodynamics and special relativity from Einstein to strings books with me....shall I work on these books?

@JohnRennie I have few books with me now:griffiths intro to Q.Mech,electrodynamics,special thepry of relativity from einstein to strings...I wanna start these books,but before I do I need some advice...I dont have anyone who can help me right now.so I really wish you help me through this

@JohnRennie Hey john rennie...idk if you remember me...we used to discuss problems in problem solving strategies during my jee prep....I have gone off for a while...needed time to get adjusted to my college and stuff...i just started sem 2...BTW Im in an engineering college, but i wanna study physics,especially theoretical physics.I'm having trouble finding right stuff to study ...I dont know where to start and what all to study...

@JohnRennie Cool!

@JohnRennie I have few more questions...I'll be back after lunch..Will you be free?

@JohnRennie My entire life was a lie.I had wrong ideas on SE.How stupid was I!

@JohnRennie SO to know where abouts of an electron I do an experiment and I found out the energy the electron has and then match it with energy of an orbital that I already know and then extract quantum numbers(n,l,m) and then learn how it is distributed around the nucleus?..

@JohnRennie Do we find out which orbital the electron is in using SE?

@JohnRennie To determine the quantum numbers(n,l,m,s).If we have these numbers we can know how the electron is distributed right!..Yes: "locate" was not the right word .My bad!

@JohnRennie If I were to locate an electron in an atom what are the general steps that I have to follow?

@JohnRennie idk...(4pir^2)(dr)?

@JohnRennie ok

@JohnRennie ok

@JohnRennie Yes,I think I have basic knowledge in polar coordinates.Let's continue

@JohnRennie I would love to.But, are there any prerequisites?

@JohnRennie Could you explain the same thing in another situation.We are now trying to locate an electron around nucleus.

@JohnRennie yes!

@JohnRennie yes

@JohnRennie and this process of finding A is called normalisation?

@JohnRennie What would each choice of A represent?..I mean ,whats the difference between choosing A as 1/2 or 1/4?

@JohnRennie yes

@JohnRennie Griffiths says yes in the next paragraph

@JohnRennie I hope you have the book with you right now.The equation 1.20:could the integral on L.H.S give values greater than 1?

@JohnRennie ok for now

@JohnRennie ok for now,but whats the purpose of doing this?

@JohnRennie ok

@JohnRennie Hes says that a glance at equation 1.1(schordinger's equation) reveals that if psi is a solution ,so too is A(psi) where A is any complex constant.What does that mean?

@JohnRennie Yes the section 1.4....shall we discuss it now?

@JohnRennie I got stuck in Normalization topic in Griffiths intro to Q.Mech .The math is new to me and it also has a lot of technical details.What should I do now?....Would you recommend skipping the topic or learning the math first?

@JohnRennie Thank you for your help..I'll jump right in then!

@JohnRennie SO,I wont have any big problem directly going for griffiths intro to quantum mech?

@JohnRennie Help!

Guys I just finished high school and I wish to study Griffiths introduction to quantum mechanics.Is it necessary for me to read griffiths introduction to elecrodynamics to understand his q.mech book? Can I start directly his Q.Mech book?.....I have AP level knowledge in Physics and math

BTW..I was talking about the image of the black hole!

@JohnRennie What cool stuff can we do using the image?..I mean:Does it help in any theoretical studies?..Or it's more of a confirmation for the theories that exist?

@Thorgott ???

@Thorgott Idk

@Thorgott I just read wikipedia page on coninuous function...and I now I understand your statement..please continue your explanation

@Thorgott Nope,I only this much and I know how to deal with continuity at a point(L.HL=R.H.L=f(c))

@Mathphile do the first derivative and equate it to zero.you get x=e..find second derivative and substiutue 'e' answer turns out to be negative...so x=e gives you maximum value of x^1/x.....I dont think I answered your question..but ..did you find it useful

@Thorgott small change in input results in small change in output

@Thorgott Could you be a bit more elaborate, I didnt understand anything!

@Thorgott How do I do that?

How do I solve question 18?

@LeakyNun @loch Guys I have few calculus questions..are you free?

cool!

@JohnRennie alright.....day after tomorrow haa?

@JohnRennie For how long are you gonna stay today?

ohk!
