As for my mathematics background, I have studied mathematics that is required for engineering, with almost all my electives in Probability and statistics. Probability and Random Processes is one of my strengths and I'm pretty good with Calculus [till like an introduction, my skills when it comes...

I have a question myself regarding this. Haven't we established that any information that is to travel between two points will take a minimum time, determined by c? So, in that case, aren't we sure that nothing travels between them, because the effects of entanglement are instantaneous? Or...

@Angry_Citizen: The place where I stay, Bangalore has a nice place called Avenue road where a lot of used books are sold at extremely cheap rates. My question actually does not relate much to that. You see, you were able to "get by a semester", but there was coursework, so you knew what...

Hi all, I am a Computer Science graduate [or will be in 2012] and am planning to do my post graduate studies in Computer Science itself, because programming has always been my passion. At the same time, I joined physics forums during my high school years where I participated in topics related...

Given the date of the post, I would suggest you start a new thread with your question. Please do not bump topics so old when the post content is not explicitly related to that of the op. Thank you.

well.. that cleared out quite a lot. Thanks :D

I found this image on wikipedia: http://en.wikipedia.org/wiki/Image:Mandel_zoom_00_mandelbrot_set.jpg and i have seen this image like many times, but i have never understood as to how it is plotted. How is the value of the color decided? Plus, if it is a complex plane, how are the axes...

So, you mean to say, calculating the entropy rate would be an ideal measure for say, a video.. as in i calculate the shannon entropy for each frame and then the instantaneous entropy rate would be ER = H_i \times \frac{1}{fps} where, H_i is the entropy of the frame and fps is the frames per...

Firstly, I thank you for replying to my post. I will be using full-colour photographs, which will have around all of the luminance values on the Lab scale. I am using a range of 1000 Luminance values on my scale [from 0.000 - 1.000], and for a 1024x768 photograph, there are 1.44 million...

I wanted to find the Information Entropy (Shannon Entropy) for a given image. I basically wanted to study the effects of image compression on the Shannon entropy for a given image. I am not sure as to how to go about it. To do this, the Message Space is the image itself. Entropy is given as the...

When you consider a point x = r, such that r < R, the surface of the sphere having the same center as the Earth and a radius 'r' is the shell he is talking about.

@nuby: if you are to determine any information regarding any system, you need energy to do so. When it comes to determining information about particles, collision of the particles with photons of a certain wavelength is used. Every measure you make has an associated uncertainty: the more...

i am currently sitting in an airbus at the ahemdabad airport, on a hopping flight connecting baroda and new delhi. The flight took 20 minutes to fly from baroda to ahemdabad. And there are around 10 to 15 passengers who got down here: yes, they boarded a 20 minute flight. If you calculate the...

A nucleon is a point particle and not an extended particle. What it means is that it doesn't have an associated radius as such. no. no two quantities are ever considered to be 'the same'. However, Energy is inversely proportional to wavelength for a wave with constant velocity. In this...
