Thank you for your answers. Actually I am still not sure about which fields should I go for by now, that's why I would like to inquire for more information. But it seems to me that in undergraduate physics, the math tends to be less rigorous and abstract, so if I would go for applied maths...

Okay I see what you mean. I interpreted the question as the following: The initial state of the gas is unknown, so if I have some way to measure all 6N values, how much information would I obtain (i.e. the decrease in information entropy = the original information entropy of the system, for...

I mean, I can also take an approach like using the fact that, e.g. 1 byte is required to store a floating number, but I think the information entropy specifies the lower bound of information amount, and the way of computer to store a floating number is only one specific way of coding that may...

This is actually also my approach, but since the positions and velocities of particles subject to some specific probability distribution, and the number of bits is related to the probability of a certain event, I have used the probability distribution to estimate the amount of information.

Hello everyone. Currently I am studying for BSc. Physics in Leipzig, Germany and serious considering to change into some other fields for master. Now I am considering three possibilities: Master of engineering, computer science or applied mathematics. I have searched quite many information...

Homework Statement 1 mm3 of gas at normal pressure and temperature contains about 1015 particles. Considering the particles as point-like and classical, provide a rough, conservative estimate for how many hard drives would be necessary to store the initial conditions of all gas particles. (As...
