I hope you had a chance to see James Grime speak on Friday; even if you didn’t, you can still take the quick canvas “Enigma” quiz (look up Enigma on wikipedia to learn the basics). I will grade it — sort of — participation matters more than correctness, but if you don’t know the answers that’s less indication of participation. 🙂
Over the weekend, read pages 160-163 (about primality testing, material from before break), pages 166-167 (about Diffie-Hellman, which we finished on Friday), and pages 164-165 if you want a look-ahead to Monday’s lecture.
Monday Task C is due; homework for next Friday and quiz material for next Friday have been posted.
On Friday at 4 pm, James Grime (who does Numberphile) is giving a talk on “Alan Turing and the Enigma Machine” (click for poster). This is not one to be missed! It’s going to be really fun, and it is very relevant to our class. If you would like to earn a little extra credit toward the “Daily Tasks” portion of your grade, please attend this talk and there will be a quick canvas quiz on it open during the talk. There’s pizza and stuff afterward.
The material on Modular Dynamics is absolutely crucial for the rest of the course, so I reviewed it today in class. Please take some time now to revisit and understand it in conjunction with the worksheet and the textbook. Read pages 153-159.
We have lately had several incidents of students breaking the honor code. First, I want to thank those of you who hold this code in high esteem. It is for those of you who care about bettering yourselves and embracing learning, that I teach this course. I also hope you will forgive those who err. Secondly, I want students who cheat to recognize that they are not only harming themselves, but disrespecting and harming their peers, teachers, community and university. Cheating will not be tolerated.
The CU undergraduate Math Club (QED: quest-explore-discover) will have its next talk for Spring 2019 by Professor Jeanne Clelland, this Wednesday, April 3 from 5 – 6pm in MATH 350. Title: The Will of the People: How we vote and why it matters.
Don’t forget TASK B is due today and we have homework due Friday. Your 4th and final quiz is already friday after this coming one (Apr 12).
LATE ADDITION: Check the homework page, a typo was discovered in one problem.
This week I will be gone at a conference, but you will have a substitute teacher. I am leaving worksheets and lecture notes etc. in my absence. Please attend class as regularly, as we are covering important material.
I’m leaving up this one website post for the week. I will post under “Lectures” the worksheet material etc.
Don’t forget that Monday (the 18th) you have Writing Assignment TASK A due; that’s your task for this weekend. I will be looking at these remotely via canvas and giving feedback (via canvas) as quickly as possible after you hand them in (so that everyone is on track with a good topic before spring break!).
We will skip homework for this Friday and Homework will be due after spring break. (With the snow day and the quiz, we hardly covered any new material to test; and anyway it’s spring break.) Homework due after break has been posted.
As for “45 minute tasks,” just keep the habit but use your 45 minutes to review worksheets, lecture notes, and associated textbook material.
I may update this post with a little more detail on Saturday, March 16th.
Today (Monday) we had a worksheet, but we only just started it. Please complete the section titled “Additive Dynamics” (up to end of page 5) and then compare to this brief cheatsheet: For item 1, it should look like one big cycle; item 2 you should have two cycles; for item 3, 5 pairs; for item 4, 3 cycles; finish to the end of page 5 at home. We will pick up there on Wednesday. Also, there was a typo on the second diagram on page 6, fixed in the online version here.
Don’t forget to bring your worksheet back to class on Wed.
You have homework and a QUIZ on Friday.
YOU HAVE A TASK DUE ON MONDAY. Read all about the Writing Assignment on the menu above, including Task A. Please let me know if you have questions. Right now, spend a little time looking through the suggested topics or googling or wikipedia-crawling around, and start to zero in on a topic.
For reading, we have covered Chapter 5 up to page 139, and are now starting on Chapter 6 (we have skipped pages 140-146 for now).
Please compare your quiz (handed back on Mon) with the solutions. Spend a little time learning what you missed or were confused about.
If you didn’t attend the LaTeX tutorial, check out the Tutorial Page (in the menu above), just to check out what you missed. You might find something useful.
Finish reading Chapter 3 of your textbook. We will finish it in class Wednesday, so this is reading ahead. (Note: sometimes I assign reading ahead and sometimes afterward. Figure out what works for you and read ahead more if that’s best for you.)
I have uploaded grades to Canvas so you know what they are. You should be able to see how individual grades compare to the mean in the course. Please double-check your homework and quiz grades are correct.
UPDATE: I’m planning a Sage workshop Monday in BESC 385 (same room). (This is mandatory, not optional.)
THIS JUST IN:Math Club talk on Wednesday titled “Are Random Algebras Really `Random’ ?” in Math 350, 5-6 pm.
NOTICE: Office hours Tuesday, Feb 26th have been cancelled due to illness.
