Swapnil's Message board- III

Hi!

Due to excess comments in the last messageboard, I thought of posting the third version of it. Feel free to ask me questions or talk to me about any random topic. I would be happy if you discuss mathematics problems with me.

Regards,

Swapnil Das.

@Spandan Senapati Could you tell me. how are the chemistry teachers at FIITJEE (CMP)? Swapnil Das · 2 months, 3 weeks ago

@Swapnil Das For us CDM is the code of Chem teacher. He is a great teacher.... And very receptive..... I like his teaching.... Spandan Senapati · 2 months, 3 weeks ago

@Spandan Senapati Then why KK sir? Swapnil Das · 2 months, 3 weeks ago

Log in to reply

@Swapnil Das Coz CDM sirs strong point is organic... Physical and inorganic.... OK (you know what it means) Spandan Senapati · 2 months, 3 weeks ago

@Spandan Senapati Could you recommend me some books on thermodynamics please? Swapnil Das · 2 months, 3 weeks ago

@Spandan Senapati

Today, I'm in a great trouble, brother. Perhaps you only could help me out, please help me.

  • First of all, are you student of KK Sir ( Chemistry)?
  • The very chemistry teacher whose tuition I attend teaches very untimely topics, though nicely. I mean, he's teaching us ion electron method without Mole concept or atomic structure. How could I study both the topics together? (Atomic and Redox) They're confusing me like hell.
  • Do you attend any other chemistry tuition? How do you deal with the situation?

@Swapnil Das Yes I am..I used to ignore Chem in class 11 in pursuit of solving more of P+M. Initial phases were easy as I am pretty strong with physical chemistry. I knew most of the topics beforehand. But I joined kk sirs class. For he was teaching inorganic(believe me you will feel more of fun rather than rote learning if you go his way) . But I advise join his class coz he is probably the only one teacher who knows linking topics.. The best way.... Chem is scoring sub and don't neglect it. Spandan Senapati · 2 months, 3 weeks ago

@Spandan Senapati Hmm. Everything was alright upto now, I was discouraged for this ion electron method only. I can't solve RC Mukherjee! Swapnil Das · 2 months, 3 weeks ago

Bhaina, I need your help again :P

You just passed 11th, didn't you? If you could remember, what were the chapters of Mathematics phase test 1? Swapnil Das · 5 months, 1 week ago

Log in to reply

@Swapnil Das Basic mathematics(functions,limits,derivatives,integration),Trigonometry...That was enough to trouble us in the reshuffling test. Spandan Senapati · 5 months, 1 week ago

@Spandan Senapati Why do they keep Calculus in Phase test 1? Swapnil Das · 5 months, 1 week ago

Log in to reply

@Swapnil Das Oh phase test had basic maths,trigonometry,straight lines and circles.The calculus part is just an intro..Nothing much.Its generally taken up in class 12 Spandan Senapati · 5 months, 1 week ago

Bhaina could you please provide some advice for NSEP and NSEA to this poor guy? :P Swapnil Das · 5 months, 2 weeks ago

Log in to reply

@Swapnil Das Lol.Only we two perhaps know what's the meaning of "Bhaina"in Oriya.....See it a kind of depends how you perceive these exams.For me physics Olympiad is what I had dreamt since I left the HBCSE for the airport(I had chickenpox just on the day our IJSO OCSC started on May 4,2016.Circumstances were not quite good.I had NTSE stage 2 on 8th and I had shifted through permission my centre to Mumbai).I had appeared in class 10 where I had a score quite close to the MAS...but couldn't make.So this yr right from the very start I tried everything I could do to qualify for the OCSC.atleast.Focus on every aspect of Jee physics.Try to get everything and be dedicated to your approach....Some great books are available try reading them not all.Some are-(Kleppner and Kolenkov,David Morin,Griffiths,Arthur Beiser(Modern Physics)etc).Take your time thinking(keep on trying).You may not reach the solution but the thinking that you put into that will definitely help you.But the most important is how you percieve it.Do solve the Inpho and NSEP past q papers.See in Odisha the cutoffs are not high.This time only 4 of us(2 from 12th and I and a friend of mine)had a score greater then the Merit index...So if you do score a bit more than MAS you are through...And NSEA...that seriously is quite easy for someone who has basic knowledge of Maths(and Physics of course)...

@Spandan Senapati Knowing that you're certain of qualifying KVPY, do you give more importance to JEE or IPhO > Swapnil Das · 5 months, 2 weeks ago

Log in to reply

@Swapnil Das IPHo was the main priority in class 11(I read so much maths and physics that my Chem marks were surprisingly less).So This time I will have balanced approach towards both. Spandan Senapati · 5 months, 2 weeks ago

I had a personal question, feel free to ignore if you don't like.

What's your aim in life? What do you want to become? Swapnil Das · 5 months, 2 weeks ago

Log in to reply

@Swapnil Das Well.Pretty much I want to do research in mathematical physics/or Theoretical physics....Although I haven't explored much fields.But I would do research over corporate sector ...I like physics a lot and the use of mathematics just adds more to my interest.....But still I feel its quite hard to predict now. Spandan Senapati · 5 months, 2 weeks ago

Log in to reply

@Spandan Senapati Our interests match so much! I was recently exploring mathematical physics and found that it's much more of mathematics than physics. Theoretical physics is much better, but I don't qualify as of the IQ required. Swapnil Das · 5 months, 2 weeks ago

Log in to reply

@Swapnil Das What do you exactly mean by the IQ required????Some areas of physics do require heavy maths like string theory or relevant super symmetric ones(super string theory is what we say),Quantum mechanics(equations relating the strong coupling of quantum systems are mathematically quite challenging).But earlier both physicists and mathematicians tended to be the same.But it was the unprecedented developments that took place in math(although they were also in physics)that these two seemed to diverge..prediction of laws of nature(is want theoriticial physicists do) and explaining those through equations and their modelling(this is dealt in mathematical physics).Do search for "Edward Witten".The only physicist to win a fields medal. Spandan Senapati · 5 months, 2 weeks ago

@Spandan Senapati

  • By 'IQ required', I think that I'm not intelligent enough to deal with such prestigious and challenging areas of physics.

  • I know Ed Witten from Class 6th :P

@Pranshu Gaba Which branch did you take at the IISc? Swapnil Das · 1 year ago

Log in to reply

@Swapnil Das There is just one branch in IISc for the first three semesters (1.5 years) in the undergraduate program. We have six courses for the each of the first three semesters: Physics, Chemistry, Biology, Mathematics, Engineering and Humanities. After three semesters, we will choose one of these subjects as a major and one subject as a minor. Pranshu Gaba · 12 months ago

Log in to reply

@Pranshu Gaba What are you plans? What will you take? Swapnil Das · 12 months ago

Log in to reply

@Swapnil Das Right now, I think I will take either Maths or Physics as major and biology as minor. However, I still have a lot of time to decide, and my preference changes very frequently. I have no idea what i'll end up taking. Pranshu Gaba · 12 months ago

I would really appreciate if you reply to this very question of mine. - Do photons possess mass?

It might be that they don't have rest mass, but have relativistic mass. Or do they don't have both?

@Michael Mendrin Swapnil Das · 1 year, 1 month ago

Log in to reply

@Swapnil Das There was a time when physicists weren't sure if neutrinos had mass. Now not only we know they do, we know that neutrinos have "oscillating" mass, i.e., can vary over time, not related to relativistic effects. Unlike neutrinos, however, photons are still considered to be true massless particles. There are very few "true massless particles", the other two being the gluon and the graviton. All three are gauge bosons, respectively of the electromagnetic, strong force, and gravitational forces. Because they have no rest mass, they always travel at the speed of light in free space. All other particles that have a rest mass can be found to be traveling at considerably less than speed of light in free space.

Physics experiments have been done where light travels very slowly, but not in free space. Michael Mendrin · 1 year, 1 month ago
