    Programs PhD Scholar Leave and Research: Physics Theories and Data Analysis

    How much leave do phd scholars in physics get annualy? Is it it not possible to do research work at home,incase the student is ill and wants to be in his comfort zone during bad times? Btw if i choose a theoretical physics topic will i be free from learning computer related stuff with...

    Mathematica Minimization help in mathematica

    The soln does satisfy the constraint,but since i have included e\inequality constraints as well,why are some solutions on the boudary.Should,nt they be within in? c1+c2+...c9=2200

    Mathematica Minimization help in mathematica

    Sorry i forgot to add the following additional constraint: c2+c3+c4+c5+c6+c7+c8+c9=2200 try it now

    Mathematica Minimization help in mathematica

    My dear friend i too got the same thing but are you blind to not notice that it gives only trivial values,that is the c values are just the values of the less then equality.

    Courses What is the typical career path for a physicist?

    Hey Mr sick scientist! How dare you equate an innocent human being with noise just because they are less smarter then you are. Don't you realize that you too, are a result of lot of noisy activity in the brain.

    Black hole microstates and string theory

    Can someone give me a Pop science explanation of what do strings and Branes have got to do with black hole entropy. The no of degrees of freedom or the no of microstates of the black hole corresponding to a given macrostate is given by exp(S),where S is entropy of black hole which is related to...

    Mathematica Minimization help in mathematica

    Hi i am finding difficulty in minimzing the following in mathematica. Can someone try it out and share with me the results. Its urgent. Its a constrained minimization problem in 8 variables c2,c3...c9 Can it be tried out in MATLAB or maple? NMinimize[{1.383` c2^2 + 1.377` c3^2 + 1.2618` c4^2 +...

    Physics Is it too late to pursue a PhD in physics at 29?

    sure,i know many who have completed phd at that age,maybe in other areas like astronomy etc.. I have not heard anyone complete a phd in theoretical suff(strings,LQG etc..) at an age older then 26-27

    Physics Is it too late to pursue a PhD in physics at 29?

    Hi everyone Will i be to OLD ,if i obtain a Phd in Theoretical physics at the age of 29? I will be 24 when i get started with the phd program ,and its no way going to take less then 5 years as i am an electronics/telecom engineering graduate and have to...

    Optimizing a Linear Function with Constraint: A Tutorial on Lagrange Multipliers

    First let me clarify this is not a homework question. This part has cropped up as part of a small project i am doing on Cosmic microwave background. How would i go about minimizing the function f(x_{1},x_{2}...x_{n})=\Sigma*x_{i}*a_{i} subject to the constraint: \Sigma...

    Can Legendre polynomials be evaluated using a recurrence relation in Fotran 90?

    Is it possible to evaluate a legendre polynomial p(n,x) using the recurrence relation p(n,x)=p(n-1,x)*x-p(n-2,x) in fotran 90 {there are some other terms which i left out for brevity]

    Equation cropping up in Kronig Penny model

    Homework Statement how does one solve the following equation to obtain E as a function of K. Homework Equations cos(k*a)=P*sin(u*a)/u*a + cos(u*a), where u=sqrt(2*m*E)/h-bar The Attempt at a Solution theres no way this can be solved analytically,however how to go...

    How Many Ways Can a Natural Number M Be Expressed as a Sum of N Whole Numbers?

    if you read carefully you will find a striking resemblance of the number theoretical problem and quantum statistics,wherin \Pi(M,N) gives the number of microstates asscociated with N harmonic oscillators having total energy MhV. i read something similar in Zweibachs string theory.
