# Requesting Brilliantians' Help for Chemistry and Physics

I would like to improve on Chemistry and Physics, and want to build a foundation for the same before I start class 11 (cbse- india).

I request Brilliantians out there to suggest books and resources.

This discussion board is a place to discuss our Daily Challenges and the math and science related to those challenges. Explanations are more than just a solution — they should explain the steps and thinking strategies that you used to obtain the solution. Comments should further the discussion of math and science.

When posting on Brilliant:

• Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused .
• Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.
• Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.

Rasnick Halliday can be suggested for physics

@Agnishom Chattopadhyay Thanks. Will I be able to find it on the net?

- 6 years, 5 months ago

You can find it on flipkart.

- 6 years, 5 months ago

We are in the midst of building out the Physics Practice section, so check back often! The Wiki would also be a good resource for you to learn more about the concepts.

@Calvin Lin Thankyou sir.

- 6 years, 5 months ago

The 11th syllabus is quite different from 10th. Reading the 11th textbooks for Chemistry, in parallel with your 10th textbooks should be enough for chemistry foundation. For extra knowledge, and a head start at IIT prep, you can use Cengage Learning or GRB or K Singh.

For physics, Halliday-Resnick is really helpful. Also, using Arihant is very helpful.

@Nanayaranaraknas Vahdam Thanks a lot.

- 6 years, 5 months ago

No problem!

- 6 years, 5 months ago

Hi! @Nanayaranaraknas Vahdam - if possible could you send the NTSE paper (SAT) of last year to me...you know my mail already :D ( the state level)...Thanks :D..

- 6 years, 4 months ago

So, you're in Class-10? Writing NTSE? (If you are in class-10)

- 6 years, 5 months ago

I missed that.I think registrations are now closed.:(

- 6 years, 5 months ago

@Krishna Ar Yes, I am studying in class 10. I was planning to write NTSE, but later I dropped the idea.

- 6 years, 5 months ago

Please refer to I.E Irodov (Problems in General Physics) for solving some tricky physics question.

- 6 years, 5 months ago

Hi!You're really good in physics (mechanics). How?

- 6 years, 5 months ago

Hi,Krishna.It's great to receive complement from you. I have studied all about physics from internet.The video lectures on youtube uploaded by Pradeep Kshetrapal and Praveen Tyagi are really helpful.Also,some books like Resnic Halliday and Concepts in Physics by H.C.Verma are also very useful.I have also referred to online forums in case of confusions. You are also very good in maths.How?

- 6 years, 5 months ago

Nice to know. Well, I am not "good" at math, but maybe a "little more than decent". It can be traced back to times when I'd failed to do well in Math....after that, I worked on math...then there was a hiatus...Now I 'm back again! :D I must say its the interest! You (might) know almost all of class-11 physics! In the same way, I worked on areas of math (NT) which I liked ...Somehow I feel calculus is inhibiting me from doing physics properly though

- 6 years, 5 months ago

Yes,I agree that it's all the matter of interest.When I started solving problems in physics, calculus disturbed me a lot but then I worked on it too.I think applying concepts of calculus in physics is quite tough and interesting too.

- 6 years, 5 months ago

Hey ...can you please tell me how you tackled that problem? :)

- 6 years, 5 months ago

Sure,I will be glad to do so.

Calculus is used in the physics to deal with the situation in which things are changing w.r.t to time. We usually find a mathematical expression for that change in infinitely small time (dt) then integrate it within limits according to situation.

It is clear from the following example: Please search for problem titled " The time before they met". In this problem as bodies start coming towards each other their relative separation changes and therefore w.r.t to time their acceleration also changes.So we usually find their velocity at any general distance "x" ( x is the distance between the bodies) with the help of conservation of energy.Then we write v as dx/dt (infinitely small change in distance/ infinitely small change in time) then after integrating it within proper limits one can easily find required time. There are basically four steps in using calculus- 1) Go to a general position. 2) Choose a suitable differential quantity. 3) Find mathematical expression for the change in that quantity 4) Integrate it within suitable limits. If you want you can refer to site

https://www.physicsforums.com/threads/time-of-approach-of-two-oppositely-charged-particle.761290/ you can find similar type on question on that webpage(instead of masses here are unlike charges).

The discussion on that webpage is quite long.:)

- 6 years, 5 months ago

Thanks! I'll definitely do so! :D

- 6 years, 5 months ago

You are welcome! :D

- 6 years, 5 months ago

Krishna,which subject will you take in class 11 (maths/bio)?

- 6 years, 5 months ago

Both! :D. WBU?

- 6 years, 5 months ago

I will take maths.Bio requires too much memorization and I think I am not good at it. :(

Will you prepare for IIT or Medical (or both :D)?

- 6 years, 5 months ago

The latter! :D You?

- 6 years, 4 months ago

I will prepare for IIT. :D

- 6 years, 4 months ago

Do you attend coaching?

- 6 years, 4 months ago

I have not attended any coaching yet.But I will join coaching for the preparation on IIT in class 11, Till now I have studied mainly through video lectures on youtube and by myself.

- 6 years, 4 months ago

Even I don't attend ANY sort of coaching!

- 6 years, 4 months ago

Good to know!

According to me,studying science and maths without any guidance of teacher is not an easy task. If you have any doubt then whom you use to approach for clarifying them?

- 6 years, 4 months ago

- 6 years, 5 months ago

You are welcome.

"Concepts of Physics" by H.C.Verma is also a good book.I forgot to mention that earlier.

- 6 years, 5 months ago

Welcome! Though, you've thanked me for doing nothing at all! :D

- 6 years, 4 months ago

DC pandey is also very good

@Rajdeep Dhingra Thanx a lot

For those of you who are interested in building out Chemistry on Brilliant, and would be willing to spend time writing up great wiki pages over the next month, please send me an email (Calvin@Brilliant.org).
