I've just started programming with Python this summer, and I'm taking a course in computational physics this semester. I've been really enjoying it and programming in general, but I don't have much knowledge in computer science save for intro stuff (string/list methods, functions/classes...

So all my life I have disliked writing in scientific notation's notation as mx10n where m and n are constants, because it looks indistinguishable from m times x times 10 to the n power. Alternatively it looks like the cross product of m and 10^n, which makes little sense because m and n are not...

I recently stumbled upon Kragh's Dirac: A Scientific Biography, and got a lot out of it. Usually, biographies of famous scientists are geared toward a general audience, and are hence light on details...but the "scientific biography" is a survey of the subject's scientific work, with little or no...

I came across this blog entry on how to read and understand a scientific paper and thought I'd share it here. It's very accessible and right on the money IMO, especially point 2 which is very basic but I often see people fail to do. Enjoy all :smile...

I'm asking this question here on a physics forum because a physics question sparked this off. However, it is applicable to all aspects of scientific knowledge. I am looking for a scientific knowledge dependency graph. This is one centralised database which captures the specific and required...

i just want to understand what i read in my algebra book. here what it says: a measurement of 83200 ft. converted to (8.32)x10^4 ft. is now accurate to the nearest hundred feet. if we write (8.320)x10^4 the measurement is now accurate to the nearest ten feet. i want to know why it is nearest...

I'm curious but usually negative exponents mean you're going to put those numbers on the bottom (sorry forgot the exact term it is much earlier than I normally get up) (example 6^-1 =1/6 so why is scientific notation different? Or is it? (Ex: 5x10^-3=.005)

Is that a "real" scientific journal? Look carefully! Article in today's New York Times about the increasing number of open-access scientific journals, some or many of which have questionable legitimacy: Scientific Articles Accepted (Personal Checks, Too)

Hi everyone. I've been looking at some computer aided design software, FreeCAD, and while it's to my understanding that engineers use programs like this constantly I wanted to ask if anyone knew if there programs are used in scientific computing or computational science and engineering. From...

Hi. I'm looking for a calculator similar to the Casio fx-911es plus, but with programming capabilities,or at least simply a small expression that I can write and save to. The fx-911 is mostly good, but it annoys me that it clears memory on Power off (minus the 8 variables). I used to have...

Hi everyone, as an undergrad in Pure math I have to take two classes of C and C++ programing. I also have to take a mathematica class. I really donMt mind because I love programing and I'll probably get more class like this. But I'm wondering what good is C and C++ when one can use mathematica...

How do you submit a scientific paper and who do you submit it to?

Homework Statement Hey guys, I'm working on an undergraduate engineering project which requires us to read a paper and replicate certain graphs using matlab. While reading the journal I hit a slump where one of the graphs stated that the data points were on a different paper. I...

The idea of varying one thing but keeping others constant is central in scientific analysis. People want to know, other things constant, the effect of taking vitamins, smoking or drinking alcohol, just as examples. Is the idea of the partial derivative analogous to scientific empiricism's...
