2. Precession Nutation and Spin

Hi guys ! Im trying to get my head round precession, nutation and spin. Suppose I have a cylinder of height L, base radius R. Initially it is just spinning about its central axis (i.e. line joining cone tip to the centre of base). In this scenario, centripetal acceleration experienced by say...

Hmmm..interesting
6. Greek/hindu Etcmythology.why ?

We all know that about the Greek Gods and the various stories and beliefs related to them.Similarly many Gods exist in the Hindu culture.At the same time Christianity and Islam also preach about Gods,but mainly one.All of this is based on the writings of people in the past.Now they might be...
7. What if we are all wrong ?

A thought just occurred to me.We have made so many scientific discoveries over centuries.Many physicists believe that in 50 years time there won't be anything else left that needs to be discovered.What if what we think about things is wrong ?.After all we fix frames of references,we define...
8. Compton Scattering Experiment

Thanks mate ! that was exactly my mistake.I can't believe I made that error :cry: but oh well !. :rolleyes: Cheers again ! This world needs more people like :approve: you
9. Compton Scattering Experiment

Oh by the way,i used the equation : dL=h/mc (1-cos angle) and i got dL=2.43 E -12 Since the energy reduction is 1 % i did hc/L-hc/L' =0.01 and L'=L+2.43 E -12 so we end up with a quadratic : L^2 - (2.43 E -12)L-(4.83 E -35)=0 Solving I got, L= O or -2.43 E -12 Hence...
10. Compton Scattering Experiment

Any ideas how to do this question ? In a Compton type experiment X-rays scattered through 90 degrees suffered one percent reduction in energy.What was the incident energy of the X-rays ? You can assume that the electron coiled non-relativistically. Any help would be really appreciated ...
11. I Want To Ask A Question But How ?

Thats a brilliant point there hypnagogue ! I never thought of that.If there was a law giver,then how did he come into existence in the first place ?.Boy ! this is amazing isn't it ?.It almost ends the argument as to whether there is a law giver or not. Suppose there was a law giver then.Then...
12. I Want To Ask A Question But How ?

We are all human beings on a planet called earth.Many things happened on this planet which resulted in atoms : the basic structural unit of matter to combine to form what we call 'life'.Not many planets were lucky to see this happen.But different kinds of atomic combinations took place to form...
13. Modeling a Saturn V launch

Well as far as Physics is concerned in India we did a bit almost everything.There are no classifications like astrophyiscs,nuclear physics etc..All students aspiring to be doctors or engineers/scientists had to do physics and it included the basics of all branches of Physics : Mechanics,Nuclear...
14. Modeling a Saturn V launch

Stage-1 is nothing but Year-1.Most students here go straight to Stage-1 after completing their A-Levels.But I decided to start from Stage-0 which is basically a kind of Foundation Year where we did basic Maths,Physics and Computing[like how to use search engines and go to a website and stuff lol...
15. Need Help On Avatar

Hi there,I've been trying for ages to get myself an avatar.But it doesn't seem to be working.Under the 'edit avatar' options there is no option regarding adding an avatar.How do I do it then ? Any help will be appreciated.
16. Modeling a Saturn V launch

Hi there,I am Dave's coursemate as well.We are in Stage-1. I am doing a BSc in Astronomy With Astrophysics [hopefully].The softwares we use now are Transmath and Maple both which are not that hardcore.
17. Hi There

I am still here,still busy at uni registering and stuff.Hope I'll be free soon to contribute !
18. Hi There

Hiya ! I do Bsc.Astronomy with Astrophysics BTW : I am a Brit,so you know...we have a different accent :tongue2:
19. Hi There

Heya ! Thanks for welcoming ! i don't see why people get scared and run away :confused: .Anyways i am here to stay.Might be busy with loads of stuff to do at uni but i'll try my best to pop in and have fun frequently! :cool: Bye for now ! :smile:
20. Hi There

Hello everyone ! I've just joined this forum.I am a university physics student.Just wanted to drop in and say a big HI ! to everyone !
