What is Computational: Definition and 319 Discussions
Computation is any type of calculation that includes both arithmetical and non-arithmetical steps and which follows a well-defined model (e.g. an algorithm).
Mechanical or electronic devices (or, historically, people) that perform computations are known as computers. An especially well-known discipline of the study of computation is computer science.

Hi all,
I'm having a course on computational chemistry, as part of a bachelor curriculum. We have a project that is due to 4 weeks and I'm failing to find an interesting idea for this project that has to be done using Python. It can be anything, as long as it involves chemistry and coding...
I am a transfer student in the states, I am considering pursuing a BS in computational applied physics.
I do not want a PHD in physics, but I do love the subject.
For you computational physicists in industry, do you like your job? Are there future opportunities for someone pursuing a BS in...
Can you recommend me a source to self study computational materials science? I am currently doing an internship and want to study in my spare time for materials science. I will take a course named computational methods in materials science but I want to learn it earlier than that but I can't...
hello
I am interested in computational physics at an amateur level
is it worth while learning complex numerical methods with C++ /Python to solve partial differential equations as well as for other physical applications while a software such as mathematica can do the job for you ?
Hi, I understand there is computational research as well as completely theoretical research compared to experimental research. I was curious about what they are like. Could anyone point out some good papers?
Thanks.
In my late twenties, currently working as a data scientist in the UK, looking to sit A level maths, further maths and physics as a private candidate (not going through a distance learning provider) and pursue a joint degree in physics and computer science (which I know both St Andrews and...
Hi everyone,
I just started graduate school and I've been working in an experimental fluid mechanics lab. We have a shock tube and run tests on studying supersonic and hypersonic airflow under different conditions. We use Schileren imaging and transducers to take measurements during tests. We...
Hello,
I have the opportunity of choosing an elective course on control theory before embarking for my master's program in computational neurosciences and I am weighing the pros and cons. I am looking for advice from PF members who specialized in this field.
Since I have chosen enough courses...
Homework Statement:: I need to draw circuits involving quantum gates and quantum states
I would like a platform that allowed me to draw quantum computation circuits. That is, that it provides me with the schemes and allows me to write in latex.
Many thanks in advance.
I am using MPLAB X, everything is working great when I work on examples that require smaller or no preload at all, I do not understand why that is the case, is there a limit to the TMR0L?
Hello please help asap,

I'm a graduate student and am interested in learning computational solid-state physics.
Ideally, I'd like a textbook which covers solid-state physics and the time-dependent semiconductor Bloch equations from a computational perspective.
Does anybody have any suggestions?
Hello,
I was going back to university for Grad school (Master's degree) this fall in Electrical Engineering, but since my application and admission, the uni created a brand new program in computational neurosciences, and I am heavily considering to follow this path instead. Thrilling!
However...

Hello,
I have a question about the measurement of a qubit in the computational basis. I would like to first state what I know so far and then ask my actual question at the end.What I know:
Let's say we have a qubit in the general state of ##|\psi\rangle = \alpha|0\rangle + \beta|1\rangle##. Now...
For my end-of-semester project, I was tasked to investigate an aspect of magnetism/magnetic materials, to do some literature review on the topic, and code a mathematical model and display my results graphically. I couldn't find anything I wanted to do, so I asked the professor to assign me a...
I am currently learning to code by auditing Harvard's CS50 course on edx. I am mainly interested in pursuing a theoretical physics major in the future. What I would like to know which scientific computing software/language (as in OCTAVE, SCILAB, FORTRAN, JULIA, etc ) can I learn alongside which...
I have given a metric in terms of the spherical coordinates ##(r, \theta, \phi)##. The problem is that I need to find the Riemann/Ricci Tensor and Riccl Scalar from the given metric by using code. I wonder what type of language (such as Python, Mathematica, Matlab, etc.) I should use it to make...
I know I'm not very good in abstract math, but it still feels more challenging and less mundane than the high school and elementary calculus courses I have been trying to bring myself to review nowadays.
Part of me feels complacent about the idea of reviewing stuff I've not touched in quite...
I have my MSc in 'Computational condensed matter physics'. I used VASP package for simulation during my MSc. and i am also well experienced in FORTRAN programming language. Can anyone give me short note about 'PhD in computational physics'? so that can continue my PhD in 'Computational Physics'.
Hi I am planning to do phd in computational astrophysics or planetary science or scientific computing simulation (least preferred in case i am not allowed to the other two). Right now I have bachelors in computer science and planning to do masters in the same. My query is should i join...
Hi PF!
I'm running a two-phase simulation, which takes a long time to run. The simulation is simply a partially filled tank being drained in zero gravity, and the tank is a little smaller than a mailbox (~ 160 X 40 X 40 mm). Before running the simulation I would like to know if my mesh is...
Hello. I am not sure if this question is relevant to be asked here but anyway please help me if possible. I have just completed my undergraduate degree in Applied Physics and I am interested to pursue my MS in accelerator physics. Since I haven't taken any course in accelerator physics, atomic...
I'm working on a PhD in condensed matter computational physics, particularly with method development. My plan is to go into industry afterwards, and out of curiosity I've been looking at job listings. It doesn't look good to be honest. Listings for physicists mainly require some type of lab...
As a Computer Programmer, it's hard to wrap my head around Quantum Entanglement and non locality being explained in the context of Classical Physics. In other words, if the universe at it's core is physical where does Quantum Entanglement fit within a physical picture of reality?
