Week One Meeting: §1.1 – §2.2

Week One’s Archived Video

For those who may have missed it, the video recording of our first meeting follows below.

I would usually intimate that some may also use it for review, but it primarily contains a brief overview of some of the resources available along with some administrative material overview. It’s much more scant on actual mathematics than I hope/expect they will generally be in the future.

Administrative Note

It appears that we had over 20 people for the first session, though we’re limited to 10 active participants who have access to streaming their audio/video into the session. Apologies to others who weren’t able to more actively participate.

Keep in mind that one should hopefully still be able to add additional material via the hangouts IM functionality or by the Q&A functionality (see notes below). For those who are in the audio/video portion of the hangout, you’ll be expected to participate and contribute to the discussion.s (Perhaps you might present a problem/solution to the group?)

If you don’t have much to say (or don’t have the proper equipment (webcam or microphone)), kindly “step” out of the broadcast and watch the live stream for a while and allow others to have a shot as well. Perhaps we might arrange some method for people to rotate in/out on a regular basis? Suggestions for this are welcome.

Those not actively participating in the session can always watch the live stream through the group’s YouTube channel.

I did notice one or two interesting side-conversations taking place within the hangout’s chat (though I’m at a loss to know if/where it was archived). At present, we’ve got more than enough time in these sessions that instead of typing respondents are more than welcome to bring up their commentary to supply everyone with a more fleshed out conversation. (There does seem to be a difference between the IM/chat within the main window of the stream and that from the separate hangouts window, which is archived and accessible after the fact, so perhaps using the latter is preferable for archive purposes, as well as being more accessible to the balance of the group.


Google Hangouts has a functionality known as Q&A to which one can write in questions that the group can work on answering during the session.  To access it at any time, go to the page for the hangout, click on the “play button” in the video portion of the screen, then in the top right hand corner of the “video” (which obviously won’t be playing until the set meeting time) click on the 3×3 square grid (just to the right of the question mark icon), and choose the Q&A pop up option. This will open up a bar on the right hand side of the screen where one can click on ask a new question at the bottom to post their question.

You can also always register at the group’s main site and post your questions there for everyone to work on/answer via the comments section during the week

Coming Up: Week Two §2.3-§3.2

This week’s Google Hangout (RSVP here) will cover problems/questions from week two of the syllabus:

  •  2.3 Ologs
  • 3 Fundamental Considerations in Set
  • 3.1 Products and coproducts
  • 3.2 Finite limits in Set

Everyone will generally be expected to have read the appropriate sections and bring their questions/issues so the group can attempt to cover and clarify any issues anyone may be having.

If it helps one or more people to ensure that they’ve got the material down well, I’m sure the group would welcome anyone who might like to present/walk their way through one or more of the problems in the relevant sections – particularly problems whose answers left out some reasonable level of detail. If you’d like to offer to do this, please put a comment in below, so we can schedule some time during the session to accommodate this.

Though we’re off to a “slow” start, things will pick up rapidly as we progress, so please don’t hesitate to ask questions here on the blog, through hangouts, or via anyone’s office hours.
