Online Teaching Methods

[caption id="attachment_19517" align="aligncenter" width="499"] Sharing my live virtual chalkboard while online teaching using Zoom (the cable for the iPad is for power only).[/caption]It is an interesting time for all of us right now, whatever our walk of life. For those of us who make our living by standing up in front of people and talking and/or leading discussion (as is the case for teachers, lecturers, and professors of various sorts), there has been a lot of rapid learning of new techniques and workflows as we scramble to keep doing that while also not gathering in groups in classrooms and seminar rooms. I started thinking about this last week (the week of 2nd March), prompted by colleagues in the physics department here at USC, and then tested it out last Friday (6th) live with students from my general relativity class (22 students). But they were in the room so that we could iron out any issues, and get a feel for what worked best. Since then, I gave an online research seminar to the combined Harvard/MIT/USC theoretical physics groups on Wednesday (cancelling my original trip to fly to the East Coast to give it in person), and that worked pretty well.

But the big test was this morning. Giving a two hour lecture to my General Relativity class where we were really not all in the same room, but scattered over the campus and city (and maybe beyond), while being able to maintain a live play-by-play working environment on the board, as opposed to just showing slides. Showing slides (by doing screen-sharing) is great, but for the kind of physics techniques I’m teaching, you need to be able to show how to calculate, and bring the material to life – the old “chalk and talk” that people in other fields tend to frown upon, but which is so essential to learning how to actually *think* and navigate the language of physics, which is in large part the diagrams and equations. This is the big challenge lots of people are worried about with regards going online – how do I do that? (Besides, making a full set of slides for every single lecture you might want to do For the next month or more seems to me like a mammoth task – I’d not want to do that.)

So I’ve arrived at a system that works for me, and I thought I’d share it with those of you who might not yet have found your own solution. Many of the things I will say may well be specific to me and my institution (USC) at some level of detail, but aspects of it will generalize to other situations. Adapt as applies to you.

An Update!

Well, hello to you and to 2019!

It has been a little while since I wrote here and not since last month when it was also last year, so let’s break that stretch. It was not a stretch of entire quiet, as those of you who follow on social media know (twitter, instagram, Facebook… see the sidebar for links), but I do know some of you don’t directly on social media, so I apologise for the neglect.

The fact is that I’ve been rather swamped with several things, including various duties that were time consuming. Many of them I can’t talk about, since they are not for public consumption (this ranges from being a science advisor on various things – some of which will be coming at you later in the year, to research projects that I’d rather not talk about yet, to sitting on various committees doing the service work that most academics do that helps the whole enterprise keep afloat). The most time-consuming of the ones I can talk about is probably being on the search committee for an astrophysics job for which we have an opening here at USC. This is exciting since it means that we’ll have a new colleague soon, doing exciting things in one of a variety of exciting areas in astrophysics. Which area still is to be determined, since we’ve to finish the search yet. But it did involve reading through a very large number of applications (CVs, cover letters, statements of research plans, teaching philosophies, letters of recommendation, etc), and meeting several times with colleagues to narrow things down to a (remarkable) short list… then hosting visitors/interviewees, arrangement meetings, and so forth. It is rather draining, while at the same time being very exciting since it marks a new beginning! It has been a while since we hired in this area in the department, and there’s optimism that this marks a beginning of a re-invigoration for certain research areas here.

Physics research projects have been on my mind a lot, of course. I remain very excited abut the results that I reported on in a post back in June, and I’ve been working on new ways of building on them. (Actually, I did already do a followup paper that I did not write about here. For those who are interested, it is a whole new way of defining a new generalisation of something called the Rényi entropy, that may be of interest to people in many fields, from quantum information to string theory. I ought to do a post, since it is a rather nice construction that could be useful in ways I’ve not thought of!) I’ve been doing some new explorations of how to exploit the central results in useful ways: Finding a direct link between the Second Law of Thermodynamics and properties of RG flow in quantum field theory ought to have several consequences beyond the key one I spelled out in the paper with Rosso (that Zamolodchikov’s C-theorem follows). Im particular, I want to sharpen it even further in terms of something following from heat engine constraints, as I’ve been aiming to do for a while. (See the post for links to earlier posts about the ‘holographic heat engines” and their role.)

You might be wondering how the garden is doing, since that’s something I post about here from time to time. Well, right now there is an on-going deluge of rain (third day in a row) that is a pleasure to see. The photo at the top of the page is one I took a few days ago when the sky was threatening the downpours we’re seeing now. The rain and the low temperatures for a while will certainly help to renew and refresh things out there for the (early) Spring planting I’ll do soon. There’ll be fewer bugs and bug eggs that will […] Click to continue reading this post

And So it Begins…

It’s that time of year again! The new academic year’s classes begin here at USC today. I’m already snowed under with tasks I must get done, several with hard deadlines, and so am feeling a bit bogged down already, I must admit. Usually I wander around the campus a bit and soak up the buzz of the new year that you can pick up in all the campus activity swarming around. But instead I sit at my desk, prepping my syllabus, planning important dates, adjusting my calendar, exchanging emails, (updating my blog), and so forth. I hope that after class I can do the wander.

What will I be teaching this semester? The second part of graduate electromagnetism, as I often do. Yes, in a couple of hours, I’ll be again (following Maxwell) pointing out a flaw in one of the equations of electromagnetism (Ampere’s), introducing the displacement current term, and then presenting the full completed set of the equations – Maxwell’s equations, one of the most beautiful sets of equations ever to have been written down. (And if you wonder about the use of the word beautiful here, I can happily refer you to look at The Dialogues, starting at page 15, for a conversation about that very issue…!)

Speaking of books, if you’ve been part of the Science Friday Summer reading adventure, reading Hawking’s A Brief History of Time, you should know that I’ll be back on the show on Friday talking with Priyamvada Natarajan, producer Christie Taylor, and presenter Ira flatow about the book one more time. There may also be an opportunity to phone in with questions! And do look at their website for some of the extra material they’ve bene posting about the book, including extracts from last week’s live tweet Q&A.

Anyway, I’d better get back to prepping my class. I’ll be posting more about the semester (and many other matters) soon, so do come back.

Take Your Pick

I’ll at two festivals this weekend, which I admit seems a bit over-ambitious! Let me tell you a little about both.

One event is the Los Angeles Times Festival of Books, which you’ve read me talking about many times over the years (that’s a photo from 2015 above). It’s the largest such festival in the USA, and is a wonderful celebration of books and related things. It is on Saturday and Sunday.

The other event is the San Diego Comic Fest, which also runs through the weekend (although it starts Friday). Don’t mix this up with ComicCon (although there are connections between the two if you care to dig a little to find out).

As I write this post I’m actually basking in the sun as I ride on the train (the Pacific Surfliner) from Los Angeles to San Diego, as tomorrow I’ll be giving a talk at the comics fest. Here are the details:

London Event Tomorrow!

Perhaps you were intrigued by the review of The Dialogues, my non-fiction graphic novel about science, in Saturday’s Spectator? Well, I’ll be talking about the book tomorrow (Thursday) at the bookshop Libreria in London at 7:00 pm. Maybe see you there! #thedialoguesbook

A Chat with Henry Jenkins!

Yesterday Henry Jenkins and I had a great chat as a Facebook Live event. The video is here. The conversation started with the movie Black Panther, but wandered into many topics related to culture, media, science, representation, and beyond. Among other things, we talked about what we enjoyed about the movie, what graphic novels and comics we’re reading now, and what comics source material we’d love to see given a film treatment. Oh, yes, we also mentioned The Dialogues!

Enjoy!

Conversation Piece

I wrote a piece for The Conversation recently that is making the rounds, drawing on lots of research sources (including reading some comics from the 1960s!). You might like it. Here it is:

The hidden superpower of ‘Black Panther’: Scientist role models

File 20180207 74473 zbs0ny.jpg?ixlib=rb 1.1
King of a technologically advanced country, Black Panther is a scientific genius.
Marvel Studios

I’m not the first to say that the upcoming Marvel movie “Black Panther” will be an important landmark. Finally a feature film starring a black superhero character will be part of the Marvel Cinematic Universe – a successful run of intertwined movies that began with “Iron Man” in 2008. While there have been other superhero movies with a black lead character – “Hancock” (2008), “Blade” (1998), “Spawn” (1997) or even “The Meteor Man” (1993) – this film is significant because of the recent remarkable rise of the superhero film from the nerdish fringe to part of mainstream culture.

Huge audiences will see a black lead character – not a sidekick or part of a team – in a superhero movie by a major studio, with a black director (Ryan Coogler), black writers and a majority black cast. This is a significant step toward diversifying our culture by improving the lackluster representation of minorities in our major media. It’s also a filmmaking landmark because black creators have been given access to the resources and platforms needed to bring different storytelling perspectives into our mainstream culture.

Last year’s “Wonder Woman” forged a similar path. In that case, a major studio finally decided to commit resources to a superhero film headlined by a female character and directed by a woman, Patty Jenkins. Female directors are a minority in the movie industry. Jenkins brought a new perspective to this kind of action movie, and there was a huge positive response from audiences in theaters worldwide.

Above and beyond all this, “Black Panther” also has the potential to break additional ground in a way most people may not realize: In the comics, […] Click to continue reading this post

Two Events of Interest!

This week there are two opportunities to hear me talk about The Dialogues in person, for you to ask questions, and to get your own personally signed copy!

On Thursday at 7:00pm I’ll be chatting with writer M. G. Lord at Vroman’s bookstore in Pasadena. We’ll talk about the book of course, but probably about science and art and writing and a whole lot of things in general. There’ll be a Q&A of course. Then I’ll sign the books you bring to me. More details here.

On Friday at 7:30pm I’ll chat with Griffith Observatory’s curator Laura Danly as part of their excellent All Space Considered show. It’ll be up at the Observatory and there’ll be a Q&A and of course books on hand for you to obtain and I’ll sign them for you. More details here.

Come to one, or come to both if you like, as time, geography, and tastes dictate. They’ll be quite different events with different emphases!

Noted…

Last week the always-interesting Maria Popova of Brain Pickings wrote a piece about the book. I was pleased to see what she wrote because it was clear that she really understood many of the several things I was trying to do in making the book. (I say this because my expectation is usually that people aren’t going to click with it because it does not fit narrow presuppositions for either a non-fiction science book or for a graphic novel.) So this was a very pleasant surprise indeed. There’s no point trying to paraphrase her, so let me simply point you there with this link.

The book also made the roundup of top Science Books for 2017 on NPR’s […] Click to continue reading this post

Unexpected Throwback!

Wow, I’ve really got something good for Throwback Thursday! A large white envelope arrived in my mailbox*, addressed to me in handwriting. My first thought was that it was yet another sheaf of papers with someone’s very earnest “Theory of Everything”, helpfully sent along for me to discover that indeed the science world has “got it totally wrong”: the universe is in fact made of (fill in the blank – let’s say parmesan cheese?) which interacts via (hungry angels tethered together by fondue strands?) and so on and so forth, and all I have to do is “work out the math for me because it is not my strong point” and it’ll all work out… “you’re welcome”.

But no, it was not. I don’t open things like this without caution, for various reasons, and often I throw them away, but there was something strangely familiar about the writing and so I took it away to (maybe) open later.

Then it struck me. It was my handwriting! Huh? How could that be? Was I […] Click to continue reading this post

Upcoming Panels at SXSW

(Image credit: I borrowed this image from the SXSW website.)

It seems that even after finishing the manuscript of the graphic book and turning it in to the publisher*, I can’t get away from panels. It’s a poor pun, to help make an opening line – I actually mean a different sort of panel. I’ll be participating in two (maybe three) of them this Saturday at the South By SouthWest event in Austin, Texas. I’ll give you details below, and if you happen to be around, come and see us! This means that I’ll not get to see any of the actual conference itself since two (maybe three) events is enough to wipe out most of the day, and then I jump on a plane back to LA.

They’re about Science and the media. I’ll be talking about the things I’ve […] Click to continue reading this post

Sandwich Bag Graffiti

A little while back, toward the end of December last year, I did a long stretch of days where I needed to change my routine a bit to take advantage of a window of time that came up that I could use for pushing forward on the book. I was falling behind and desperately needed to improve my daily production rate of finished art in order to catch up. So, I ended up ditching making a sandwich in the morning, instead leaving very soon after getting up to head to my office. I then stopped taking my sandwich altogether when I ran out of bread and did not make the time in the evening to bake a fresh batch, as I do once a week or so, because I was just coming back home and falling into bed.

The USC catering outlets were all closed that week. This meant that I ended up seeking out a place to buy a sandwich near my office. I found a place […] Click to continue reading this post
