The second law states that the force on a body is proportional to the rate of change of linear momentum. We work in units where the proportionality constant is 1. You could in principle, define force to be that quantity which is say, twice the rate of change of linear momentum. You would...

Thank you all. It is much clear now.

I wrote conscious; not on purpose. Maybe voluntary is the appropriate term here. What I mean to say here is why does our brain make arithmetic errors when it comes to making "conscious" or "voluntary" operations such as mentally adding two numbers. For example when someone asks us what 9*9 is...

I know the question does not strike as being specific to physics, but please, give it a look. Human brains are considered complex computing machines and are rightly so as seen by the examples around us. Why then is it that we make conscious arithmetic errors( For example: calculating...

There are other ways to charge a body. You can always add a positively charged particle to it.

No, we don't. And as far as I remember, this is not a forum where ideas of humor are discussed. You might very well have been a person who makes the common mistake. I don't need to "get a grip". Peace out. Can you cite a source? I searched extensively and nowhere did I find this convention.

In-case you're trying to refer to people who study physics, they're called 'physicists'. A 'Physician' is a professional who practices medicine. Please be more elaborate. I have not studied brownian motion in depth but I can surely say that \dot{x}(t)=\alpha(t)+\beta(t)\eta(t) can...

... Not the sort of help i expected. Incase this post was ignored because other fresh posts coming, this is just to bring it up again. Please, I need help.

okay. :)

I mean, I use windows and so do many of my college friends using physics forums. I know it's an upcoming platform but still seeing the stability of the system, it's going to stay for long and the app won't be built for nothing.

Need developers?

I'm working on a project in the field of DNA origami and need links to research papers and study content for the trapping processes and folding processes. Can anyone help?

Is the windows phone app in development?

Try solving the problem there. I faced the very same hurdle. The boundary conditions beautifully bring out the result

Thank you! This and the accompanying statements cleared a lot. I was confusing between the two. And yes, according to the law, E[g(x)] = Ʃf(x)g(x) does give the same.. In the example provided by you, where f(x) = 1/3 : x ε {-1, 0, 1} and g(x) = x2, E[g(x)] does indeed give 2/3. It is clear now.
