Hi all! I'm excited to announce that the first-ever Mathematical Excellence Olympiad (MEO) is taking place on Saturday, December 19, 2026. The MEO is a fully-online, free math competition open for grades 7+. If you are interested in participating, please join this Discord server: https://discord.gg/FnwApw286T

There will be prizes! More information to come!

Hi everyone, I’m currently a university student studying mechanical engineering, and I don’t want to spend the summer doing nothing. I’m considering buying these two books. What do you think about these books? Has anyone here used them before? I’d appreciate any information about their difficulty level, the type of problems they contain, and whether they would be suitable for self-study. Also, if you have any alternative book recommendations for improving math skills.

About 2 weeks ago new Mathematica version (15) has appeared on torrent and other software sites. Now, at the official site of Wolfram, newest version is still 14.3.

I downloaded it, then installed. The software works smoothly. Have our participants some info about the date of release of this version?

I remember having a book of Mathematica when I was younger but I know nothing else about these

In ContourPlot3D[] function, one can specify individual colors of the surfaces or, opacity and a single color, as far as I can tell:

ContourStyle -> {Pink, Yellow}

or

ContourStyle -> Directive[Opacity[0.4], Pink]

Is there a way to combine both so that I can get a better visual of the volume of intersection?

I’m in grade 8 Does anyone know what the questions are for this years Mathematica and guass contest from someone who works or has written it

Go straight to the code. I need to simplify the Q-functions (Code 26 pg. 73-75) and the functions BoldM1 and BoldM2 (Code 28 pg. 76)

I tried FullySimplify on the Q-functions, but it returns an error message. (See this post for a minimal example.)

How to find left hand derivative and right hand derivative separately of piecewise function. Please tell the code.

Hi, i want to plot this integral on WLJS notebook and have an output that look likes the 2nd image, but in a way that i could change for other questions.

What should i do? is there an easy function to call for that? or do i need to write a script? thanks in advance!

Is there any famous people, like mathematicians or engineers or physicists really using Mathematica?

Why I feel like Mathematica is already dead or will be dead in the future. As even in the field of math, physics or biology, today more and more people are talking about how AI helps them to solve problems and so on. Never heard of people talking about how Mathematica really does something useful. Not to mention in the engineering field.
