I think the reason why your hand doesn't hurt as much when you are holding the axe far from the point of impact is because the shock of the hit gets dissipated along the length of the handle. However, when your hand is close, your hand absorbs most of the shock before it reaches the other end...

Awesome! Thought no one else was interested. just out of curiosity, what is that calculus of variations book? is it printed by dover? I am looking for a text on that subject. Thanks!

Hi everyone, In 90% of social forums there is a thread where people post their computer/home office set up..etc. Given the number of people asking for which books to self learn a particular branch of physics, which books to use for a specific course...etc How about we post pictures of our...

Calculus 3 is important when studying subjects like thermodynamics, classical mechanics and electrodynamics, but you also need a good foundation in partial differential equations (which i think is very important in classical physics). Since the stuff you learn in calc 3 (curl divergence..etc)...

http://www.amazon.com/dp/069108131X/?tag=pfamazon01-20 this one only talks about Everett's Many worlds interpretation but its one of the most interesting one :D a quick search on amazon.com and got this http://www.amazon.com/dp/0691036691/?tag=pfamazon01-20 Take a look at the contents see if...

I have the quantum theory by bohm. I used it last year along with griffiths while taking my first intro QM course. Bohm expects you to know classical mechanics and E&M. In fact, he used E&M in the first chapter actually. So I think its better to stick with Griffiths or Shankar for an...

marcus thanks for the link, I did watch that video 2 weeks ago when I first started the research. I found it difficult to follow because he seemed very nervous. Not sure if it is because it is a string conference. I will watch it again and see if I can understand more. Atyy, I read it from...

Hi there thanks for all the replies. I knew that QED is a special relativistic theory but I didn't know that causality would get screwed up in a background dependent theory. Also I did read some review papers written by Carlo Rovelli and understood (I think) that a superposition of spin networks...

Hi there, I am currently doing a project on LQG and I am having troubles grasping the basics. I am just wondering if anyone here could help answer a couple of questions that I have during my study. 1.) How to use Roger Penrose's original spin-network? I read in his book that they are used to...

thank you for your reply! I am happy that I got it right :D I can see that all molecules going into the center has to go out of the sphere at some point in time, but the fact that they diffuse out of the sphere at the same rate as the particles entering the system doesn't seem very intuitive to...

Homework Statement Molecules with diffusion coefficient of 1.0 x 10^-10 m^2s^-1 are released at a constant rate of 10^10 molecules/s in the middle of a large pool and dffuse away ( assume the 3-dimensional pool is of infinite size). What is the steady state concentration 1 cm away from the...

Thanks for the reply. Too bad the Huang book is not for UG's since its pretty cheap. I am a 4th yr physics major. For math, I have taken cal i to iv, intro to pdes, an intro course in probability (1 variable continuous probability) 1 basic linear algebra and one complex analysis course. For...

I am looking for a book on basic statistical physics and kinetic theory. Is there any books that sort of helps you transition from thermal physics to statistical mechanics? I used Thermal Physics by Ralph Baierlein https://www.amazon.com/dp/0521658381/?tag=pfamazon01-20 But I am looking for...
