I was on vacation and away from data analysis and science for a while, sorry for the long time without showing up. Thank you robphy and Dr. Transport for the thoughtful answers. I could use the history from my commands or thoroughly document everything but it seems to be too much trouble to me...

Well, I do save most of my python scripts but some work I do in the form of interactive programming (ipython interpreter). Specially when I am exploring the data and testing different visualizations. And sometimes I do batches of plot that involve running a combination of custom function several...

Hello! I have been using python for my data analysis and processing needs as an experimental physicist for an year now. I have used MATLAB and originpro before and python provides me everything I need. But I am not satisfacted with my worflow specifically for plotting needs. I often find myself...

Hello Guys! I have been studying electromagnetic waves (EMW) interaction with matter lately and I just derived the results for the propagation of EMW inside linear media and perfect conductors. As it turns out, when a plane EMW changes medium (at a normal incidence) from air to (good)...

Look, I never meant to say "I do not want to study math, I want to skip every basic concept, I just want to magically use it without having any idea of what is going on". I said "I do not want to study only the math/theory, I want to study it in an applied context". I got books in the past that...

Ok, I will try to be more specific. My current level of understanding given by Bevington and Taylor: I know the most famous distribution functions (normal, binomial, poisson), I know the most basic goodness of fit measurements (chi squared) and a very basic outlier removal test (Chauvenet's...

Any help...pleaase? Think of me as a beauty in distress doomed to never understand advanced statistics unless a hero shows up!=D!

My current level of understanding of error/data analysis and statistics is based on the material I covered from Bevington and Taylor's introductory texts. I need something that covers the subject in greater depth now. My motivation comes from my job which is to come up with a better way of...

Good idea, just submitted the request. Anyway, if anybody has the workaround for this problem any help is appreciated.

Hello! I am having trouble using the SimPowerSystems library from simulink to simulate circuits (with the powergui solver). On all the circuits I have simulated so far either of the following happens: - Adding the initial current/voltage directly at the RLC branch block culminates into...

Good job Aleph, it makes sense now. Thanks!

Yes. The result is accurate since if you exclude the singularity by simply integrating from -1 to 0 and then from 0 to 2 and sum them up the answer is exactly the same. I do not know how to analytically solve this integral and, well, that's the whole point of numerical integration. I dind't...

Hello everyone! I am trying to understand why the following function does not provide problems to being computed numerically: ∫dx1/(sin(abs(x)^(1/2))) from x=-1 to x=2. Clearly there is a singularity for x=0 but why does taking the absolute value of x and then taking its square root...
