OReilly published a new book, Programming Quantum Computers. From my brief scan of it, the book looks pretty comprehensive. They use circle notation for the Qubit states and have a simulator (QCengine) to go along with the examples on github. The programming language for their algorithm...

thanks

Hello everybody, I am a master student in Theoretical Chemistry and I am working in the DFT realm. Both TDDFT and DFT applied to extended systems (eg. using QUANTUM ESPRESSO). Of course I work with these softwares from a end-user point of view, not as a developer. But anyway, even if some of...

https://www.amazon.com/dp/B00KM6ZA9I/?tag=pfamazon01-20 So I have the blue thing and the usb cord from a long time ago when I wanted to build a robot, but I don't have the bottom three (unless the bottom left hand corner one is the one attached to the blue thing). I still have the cd as well...

TL:DR; I've started an open source C# physics library: University Physics The Long Version So it turns out there's relatively little in the way of full physics libraries written in C# (the best I can find is bepuphysics which seems to be focused only on classical mechanics). With this...

Is there yet a programming language for implementing processes that use probabilistic bits (p-bits)?

The following quote caught my eye. I presume that buffer overflow, heap management, and pointer validation are the shortcomings of C that lead to insecurity. But the broader implications make me curious. What other features of a programming language directly aid security of the products...

Hey folks, thought I'd ask the experts for some help here. I know that there are LOTS of online resources to learn Linux Terminal, Microsoft PowerShell, and Python, but I was hoping some of you had some favorites that might make the learning process more efficient (in your opinion, of course)...

Hello, In grade 11 of high school, I encountered this linear programming problem on my textbook: The "alternative solution" described in the textbook as follows: Let: - ##x## : amount of plant A - ##y## : amount of plant S - ##L## : garden area - ##L_x## : area of garden for one plant A -...

My name is Martin Scholtz and I am a postdoc researcher at the Institute of Theoretical Physics, Faculty of Mathematics and Physics, Charles University in Prague, Czech Republic. I'm working mainly in the area of gravitational physics, but I am interested in different topics as well, see tags...

I recently encountered the Scratch programming language. I wonder what people think of it considering some notable (IMHO) shortfalls. I do not like the way it handles comments, the lack of returned values from "functions", and some other aspects that I think should be basic. But it does seem to...

Hi, I am an undergraduate Physics student and i have an exam on c++ programming next monday, what are the basic things I have to know in order to perform well in the exam? And how is c++ applied in physics?

I'm interested in quantum programming. So far I've managed to use Java and Python inside Datamelt computation project for physics simulations and for various statistical plots. Now I want to make a simple code that illustates quantum computing, and maybe even to visualize its principles (for...

I don't think I understood the problem clearly. What I understood is this: 1. Each food item has a specific major color-component (and, hence, a fixed mode-value of that specific color component). First, I need to calculate all mode values, and use them as constants in my program. 2...

Would physics majors benefit from learning how to do Object Oriented programming?

I’ve heard that C++, python, and IDL are most commonly used in observational astronomy research, but how common is R in the field?

Hi, Please have a look on the attachment. It says, "In a computer system, the overall processing speed is usually limited by the memory, not the processor. Programming determines how well a particular memory hierarchy is utilized. The goal is to process data at the fastest rate possible." I...

Simplex method

This is my first post so don't be too harsh. I was just looking to get additional opinions in order to make a more informed decision. Since I always had the idea of becoming an astrophysicist I enrolled in Bsc in physics engineering (5 years) here, and due to being the top student I was invited...

From what I've come to understand is that, in order to get a programming position, you have to be able to answer white board questions. Basically random things such as Fibonacci sequence methods etc... My question is : is this really the best way to asses whether someone is a good programmer or...

All the white space among words in a text file was lost. Write a C++ program which using dynamic programming to get all of the possible original text files (i.e. with white spaces between words) and rank them in order of likelihood with the best possible runtime. You have a text file of...

Dear Sirs, I'm using Microchip PIC's as programmable laboratory timer among other things, but the 100ns instruction cycles are not adequate anymore. So I thought of beefing it up with a 5M40Z MAX-V CPLD which has 5ns end-to-end delay, bought the programmer and downloaded the Quartus Prime Lite...

Hi I am learning kinematics. Topics include inertia tensors, cosine matrices, quaternions, Euler angles etc... To learn these topics well, I want to try working on something a bit more difficult than just the underlying math. That will probably keep me more motivated. So, I am looking for...

Hello, I am trying to get my head around the important difference between these two different styles (paradigms) of programming. I am familiar with traditional structural programming: data, variables, functions, structures. The functions are blocks of instructions that can process data, etc...

This is not a question, but a note, which I thought could help students. I thought I would share this here, as people may be looking for practice problems. My professor in the Python course I just finished recommended https://projecteuler.net/ as a site to practice using programming skills...

It looks like Javascript is the way things are heading. But I've also seen C++ and Python recommended. I don't want to waste time and energy; I've done enough of that. Any job I get will probably be based on my having a 4 year degree (STEM preferred and no gpa requirement) and programming...

hi everyone! i am not into physics, but need it now,i am a programmer workin on an IOT project...so kinda need help. i want to use a capacitor to see what passed between two plates...knowing, it is the change in dielectric after certain intervals...how do i measure the change at the other...

Hi everyone, I am new programming in Fortran and Inhave done about three or four programs that solves different problems in trigonometry, one is the basic one it gives you hypotenuse upon two sides, the other finds the theta angle by giving hypotenuse and opposite side, other find hypotenuse by...

I remember a while back someone told me that there exist programmers who don't believe in null. I thought that was a crazy idea. Until recently, as I've gotten better at OOP and have figure out that if my object has a property that is allowed to be set to null, it usually means that I am not...

Hey everyone, I wasn't sure if this belonged in the general math forum or not, so I posted it here instead (mods - feel free to move if it belongs elsewhere). What I want to know is how to properly write out a computer algorithm in proper math notation. Take this code for example: Height...

Let's say I have a service that publishes events, like eo ("Bought 100 shares of AAPL") e1 ("Bought 100 shares of T") e2 ("Sold 500 shares of TSLA") and there exist stateful services subscribing to the events and whose state depends on the events being processed successfully and in the correct...

Hi, My question is if there are any computer programming or front-end web development certifications that I can earn online for free or cheap. I already completed FreeCodeCamp and a few other coding bootcamps online. I also signed up for my bachelor's degree equivalent on Open Source Society...

Been tracking down the most unusual bug I've seen in 40 years of programming (mostly in assemlber and C). It manifests in the test suite for an object oriented XBase language implementation that's been ported everywhere from Palm Pilot to OS/2 to the Blackberry tablet to Windows to, now, Qnx7...

I'm majoring in physics and I'm planning on pursuing computational astrophysics in graduate school. Will a second major in computer science/programming look good to graduate schools, and/or will it give me great advantages in the field of computational astrophysics or astronomy?

I have a project to make the solar system. I am trying to start from somwhere. On the notes it says that we need to start by creating a System of Particles Two-body simulation (Circular motion) Implement Gravitational acceleration Each particle (planet) could have its own field. I.e. Each...

Hi, I am an aspiring Theoretical Physicist. I've heard that you need to know many programming languages to become a Physicist, but I have never learned a single programming language in my life and I am 16-17 years old now. Is there any chance of me still becoming one? Is there anything I can do...

I’ve been a school teacher for 6 years, and I want to get into coding. I’ve been told by a CS professor I know that my background is very sought after in the tech industry, and I would be very competitive if I got into coding. Is this true? What’s the best route, bootcamp, nanodegree, etc.? What...
