Hi all, you should start to see Exercises available in roughly half of the lessons for additional practice. The rest of the lessons will have exercises visible not too long after this post goes up. The exercises are ungraded, but provide you extra practice to build your confidence as you learn the material. Do let us know here if you have questions about newly visible exercises or anything else.

THANK YOU!

Noted already, actually :)

I will look forward to more exercises~

Hello John,

You did a good job teaching this class. Previously, I thought game theory would be boring, but I found the patterns intriguing. In particular, I enjoyed seeing graphs employed in Markov chains and would like to delve deeper into that. Thank you for sparking my interest! And thank you for the reasonable length of the final. REALLY, THANKS!

Also, your use of pauses in your videos made them extremely easy to listen to.

Take care, Lori

I was wondering if there might be a problem with Quiz 7 and maybe on Quiz 8. I completed Quiz 7 and clicked the "Get Results" and have no feedback. The system seems to hang. I restarted my Mac and even tried a different browser with no success. Any feedback is appreciated. Thanks, Randy

That's correct, the exercises are not yet up in the framework so that behavior is expected (for now).
POSTED BY: John McNally

The exercises for some lessons should now be visible in the course framework, stay tuned for updates on the rest that will also be appearing shortly.

I'm having inordinate difficulty reliably creating a matrix in the WL. I don't understand why the first statement creates a 3x3 matrix and the second does not:

I am registered for the series but could not attend. Where can I find the associated notebooks to download? Thank you.

George, to get the links, the simplest thing is to send an e-mail to wolfram-u@wolfram.com. The URL of the beta framework was included in reminder e-mails for the class sessions for the later sessions (8-10). It wasn't released until then. I don't think students are supposed to share the links here.

You should have links to the lecture archives in the "Recording available" annoncements you got from Wolfram U daily.

Hi, I'm not sure why you may not have gotten an email about the recording being up; however, there is no requirement to attend the live sessions. Live sessions are obviously nice, but life happens and you can definitely catch up on the recorded versions.

Hi John,

I have a conflicting work commitment today. What is the policy regarding a missed class or online discussion? (Obviously, I'm new to this.)

Yes, thanks Phil for answering this! And like Phil said, don't worry about missing a day. The text materials and the video links can both be accessed outside of the "live" time. The live time is obviously nice for being able to ask questions immediately and easily, but the design of all the courses is such that people can learn asynchronously too.

Phil, when random cyber coin flips start to correlate with world events, it’s a good time to change the random number generator.

Thanks, Daniel. I can't accept a casual/pseudoskeptical dismissal of the Heartmath work. The details of Heartmath's random coin-flippers are well-documented; they are extremely sophisticated devices. If you examine those details and see some obvious reason they are inappropriate for the job, I (and others) would appreciate learning those details. But casually dismissing their devices with no specifics isn't advancing anyone's understanding.
POSTED BY: Phil Earnhardt

My response skeptical, not pseudoskeptical.

Nor is it casual. I’ve worked with RNG’s and with RNG test suites. The idea behind most (or perhaps all) such tests is to probe for statistically significant correlations. This is especially the case for testing of iid uniform random bit streams. Ergo if their RNG’s are showing such correlations then they are not doing a good job generating random bits.

I looked at the site by the way. I was not able to find details about their bit generators, other than that they are apparently considerably scaled up in volume this past year.

Thanks for your course, when will this https://www.wolfram.com/wolfram-u/courses/mathematics/introduction-to-discrete-mathematics/ course begin ? Very interested to sign up

Have a great day or night

Hi Roberto, the study group for Discrete Mathematics (which is different from Finite Mathematics) began on Oct 16, and the full versions of courses will go live not too far after their study groups conclude

John, the last 2 Daily Study Groups offered this fall (Discrete Math and Multivariable Calculus) commenced with an unreleased course framework. With Discrete Math, the framework Beta was released on Day 8 of the course; with MVC, I believe it was released in the third (final) week. I'm awfully fond of your work and presentation, but I'd strongly prefer to do courses where the framework was ready to rock on Day 0 of the course.

Will the Finite Mathematics course framework be ready to go on November 6? TIA.

@Wolfram U: if a DSG is commencing before its course framework is ready, could you please include a disclaimer noting that in the course announcements?
POSTED BY: Phil Earnhardt

Hi Roberto,

This is Marc, the instructor of the course for Discrete Math. The study group just finished today, the course framework will be available in a few days.

Happy learning! Marc
