Updates and useful bits 

  • [2018.03.29] There will be a review session scheduled to help you start preparing for the final exam (which is scheduled for April 9th). The review session will take place in the Gauss lab next Wednesday (4/4) from 3:30-5:30. You are strongly encouraged to attend!
  • [2018.03.14] As you may have noted, there has been no assigned reading for the Fourier section of 2030. That is chiefly because the text (Stickler and Schachinger) do not even cover Fourier analysis at all(!?!). Nonetheless, there are plenty of decent refs to use as a starting point available online. One of these can be accessed here (courtesy of Agilent).
  • [2018.02.28] Final exam date is now determined: Monday April 9th at 9 AM (Note: Classes end on April 6th, so this is very soon after that!)
  • [2018.02.05] This link re a short read on quantum computing might be of some general interest....
  • [2018.02.05] Remember that the 2030 midterm will take place in class on Friday 2/9. Note that it will NOT in in the regular class room, but instead in Curtis G (CLH G). Plan to arrive as early as possible so to make best/full use of the 50 min. exam period. Please note that course policies re exams as laid out in the syllabus. Also, there will be no in-class lecture on Wednesday 2/7 (instead there will be an extended review session in the afternoon in the Gauss lab run by the TA, Chris J.; that starts at 3:30 on 2/5) nor on Monday 2/12. Regular lectures will resume 2/14 following the midterm. Good luck!
  • [2018.01.31] A reasonable request(s) was made and I'm inclined to try to be helpful: there will be an extension on HW3 such that it is now due on Friday 2/2.
  • [2018.01.26] Keep in mind that we have an upcoming midterm exam on Friday 2/9 during the regularly scheduled class time. As of this moment, it is scheduled to take place in Curtis G (CLH G). In short, any material covered in the class notes below up until 2/5 is fair game for the exam. To help prepare and give you a flavor for the exams, here is the W17 midterm. Note that topics were rearranged a bit between 2017 and 2018, so the overlap is not exact. But at least you have a (rough) sense for the style/flavor of the exam. You are allowed a single regular-sized page double-sided formula sheet which you must turn with your exam. You can put anything you want on that sheet.
  • [2018.01.26] Apologies for the cancelled class on 1/24. Was quite a bit under the weather. And still am a bit. Nonetheless, we will have class today as usual. I may just be a bit (relatively) subdued.... 😉
  • [2018.01.10] There was some confusion re the drop-in lab (my fault!). Apologies. We will aim to start proper come Monday 1/15. In the meantime, check out this link and follow through the steps there so you can get card access to the lab. In the meantime, I'll make sure the lab administrators know we are coming and update here with any salient bits. Thanks for your patience as we get this up and running.  
  • [2018.01.08] The drop-in labs will start Wednesday 1/10. Students can show up today, but Wednesday will be the first day the TA will be there. BTW, our TA for the semester is Chris James (cljames@yorku.ca).  
  • [2018.01.05] First day of class. Welcome to PHYS 2030! 
  • Note that for all assignments, you should write (and hand in a copy of) your own code. It is okay to look at and utilize the example codes provided here (or from fellow students), but you must write your own version of code (as indicated in the course syllabus). Also in order to receive full credit, you must provide sufficient (but concise) explanation as to how you arrived at your answer.
