As you may know from three previous recent posts on research (here, here, and here), I’ve been thinking and calculating a lot in the area of dynamical cosmological constant – concerning mostly (but not entirely) thermodynamics and quantum gravity. Specifically, the cosmological constant becomes the pressure variable in the thermodynamics. I think it is important, and will teach us something about things like gauge/gravity duality, string theory, black holes, and perhaps even cosmology, but I am not sure what yet. I’ve made some suggestions in recent papers, and computed some interesting things along the way.
Anyway, the larger community has not been following this story much, since: (1) It means a break with some powerful and still very fruitful frameworks where the cosmological constant being fixed is a given – like AdS/CFT – and it is not clear what that means yet, so the motivation is not super-strong; and (2) Let’s be honest, there’s no superstar working on it, so it is not going to get anyone any points. So I’ve been trying to shout about it in my little way from the periphery, as I think it might be useful, and since several people have been doing really good and interesting work on this issue for many years and it is worth more people seeing what they’ve been up to.
So imagine my pleasant surprise when I looked on the listing of new papers on the arXiv for today and saw three (!) papers on the subject, moving things forward in various ways. (They all seem to have noticed some of what I’ve [...] Click to continue reading this post
As a way of degaussing from the heat of physics research involved in producing the recent paper, I spent a bit of time getting my hand back into some proper drawing shape… I looked into some magazines and catalogues for interesting faces and found a couple.
The woman was done more or less directly in ink, which is a good challenge for the eye – you must be sure about a line before you put it down, since you’ve not got a second chance. A day or two later I sat in a cafe after a visit to a garden centre to pick up some supplies, to draw another interesting face I found (in a gardening catalogue). This was done more carefully, starting by doing a quick pencil sketch first for accurate layout, and then doing ink afterwards. Since people are sometimes curious about process, I include below a sequence of stages on this one as well. Enjoy.

As you know from my writings and sketches, I like to carry a notebook. People often ask me what types I use, or assume that I use the (increasingly fashionable) Moleskine books. I like Moleskine books (the little 3inx5in ones for example), and have used them a lot in the past, but actually I prefer the books by HandBook Journal Co., (made by Global Art Materials). The surface of the paper is more flexible, in my opinion. It has a little more tooth than standard Moleskine, which makes mark-making with pencil much surer, and it also takes wetting better, so you can work with a little wetness as well, such as lots of ink, or watercolour (paint- or pencil-based). That allows for crisp drawings like the one on the right (click for larger view – more about these sketches here), right alongside physics research musings and computations in pen and ink line on the pages shown below on the left (those notes pertain to the paper I discussed here.)
I tend to carry one of the 8.25inx5.5in landscape ones (although I love the 5.5in square ones too). (See more chat about them here.) They allow a good [...] Click to continue reading this post
Memorial Day – 26th May 2014. I arrive at downtown Los Angeles to enjoy a few moments of the pure joy of looking. Of seeing something in front of me well enough to make a rough representation of it on a piece of paper in front of me, for the pure hell of it. This is the essence of sketching. It is about seeing. I’m looking for the… something.
My hunt is over. I see the scene I want, just off the Water Court, a few minutes from the top of the (closed) Angel’s Flight rail. The sun is streaming through the portal framed by the two closest buildings. The further ones make sharp geometry against the 4:00pm sky. I’m also curious to try some new coloured pens, and I like that each building suggests a different colour. I’ve got about 15 minutes before I have to leave to pick someone up.
I sit. I start. Immediately I see the guard see me from across the way, and within a minute or two he is by my side, standing in front of me. He has the “You’re not allowed to do X” look on his face, but he’s trying to start out well. I’ve had this before, right in this public space, when a guard decided that I should not take photos of the buildings. Despite all the other tourists who do so. He begins:
You know, usually we… Are you an architecture student?
Are you an architecture student?
Well, what are you asking me, really?
Are you an architecture student? [...] Click to continue reading this post
Been a while since I got to do some sketching. It is good practice to try to do something every day, but that fell by the wayside a little as far as proper sketches went. It has been busy the last week and a bit, and my subway time has been during very busy times when there’s not enough space to get out pen and paper and sketch a person without becoming a spectacle… and during the moments where I might have caught something, I’ve actually been calculating – working out questions for the final exam in the General Relativity class, and (more recently) doing some computations for a paper I’ll tell you about shortly.
Anyway, when time is short, I sometimes like doing quick sketches with a thicker pen. Stops me from digging into the details too much. In fact, I’m really liking that as a sketch mode these days… You make your lines boldly and you’re stuck with your choices, and so it gets you thinking about what’s globally important carefully before jumping in.
It is great and satisfyingly distracting fun. Anyway, between this and that over the last day or two I did a few quick faces based on some photos I found in a [...] Click to continue reading this post
As a contrast to yesterday’s quick caricature effort, I went back to one of the pictures in the magazine and did a more careful pencil sketch. Very different kind of exercise and technique needed to coax out the things I wanted to bring forward. It is a scan of pencils, so beware that it is not as representative of what’s on the page in some ways. To add to that I really should do a lot more finish work on this one (rendering of shadows on [...] Click to continue reading this post
Lovely bit of sitting in the sun for a short while after breakfast this morning relaxing by doing some quick freehand sketches from pictures in a magazine. I was experimenting with a pen I love but don’t use much at all – One of those nice inky brush pens by Pentel. Gives some interesting lines that take some getting used to since it is quite a different mark-making tool than the pens I [...] Click to continue reading this post
As you know I am a big fan of sketching, and tire easily of the remark people make that they “can’t draw” – an almost meaningless thing society trains most people to think and say, with the result that they miss out on a most wonderful part of life. Sketching is a wonderful way of slowing down and really looking at the world around you and recording your impressions. If you can write you certainly can draw. It is a learned skill, and the most important part of it is learning to look*. But anyway, I was pleased to see this nice way of getting people of all ages involved in sketching for fun at the book festival! So I reached in and grabbed a photo for you.

It was the departmental retreat this weekend, and we all went off on a boat to an island! On the voyage back I decided to practice a little sketching, and found myself surrounded by good subjects, because a lot of people were sitting still during the crossing (it was a small boat). Since the boat was rocking [...] Click to continue reading this post
So, I don’t know why, but in addition to the catalogues I get in my work mailbox from publishers of physics books or lab equipment, I’ve started getting a lot about books in the Humanities and related subjects. Is this because those publishers know of my tendency to dabble in other subject? I’ve no idea. In any case, all of those things tend to end up pretty swiftly in the recycling bin nearest the department mailboxes. A suite of lovely new books on teaching Art History is about as valuable to me as a shiny sets of vacuum pumps or electronic controllers. I’ll admit to sometimes looking through and longing for the time I’d need in order to explore such things (vacuum pumps or Art History texts)… but then into the bin they go.
Well, earlier this week a catalogue arrived and one might be forgiven for thinking that they are really trying to get my attention with this one. It is a catalogue of Gender and Sexuality texts from Ashgate, and if the image on the cover is representative (uh, as far as I know it is not!) they’ve really developed some fancy techniques in the field!
Some of the formulae are hilarious! (And I’m trying to understand the, obviously important, inequality right in the middle…) [...] Click to continue reading this post
Some of you are wondering what I’m working on while on retreat. Well, actually there’s a nice coincidence here. I’m working on the graphic book that you may have heard me talk about a bit. “The Project” as I sometimes call it. I’ve been doing things on various aspects of it, such as reworking the description of it for various people to look at, writing new bits, and spending a bit of time pulling together various bits of the prototype story I used to start all of this back in 2010. The prototype bits have all of my experimentation and development of style and technique all over them, and so there are pages that needed a bit of rework (to say the least). So, on Monday, [...] Click to continue reading this post
While on a hiding retreat in another town or city, I like to seek out a local group that might be doing a “drop in and draw” session. You show up, pay your money, and there’s a safe environment (in a studio, a back room, upstairs of a pub, etc) for a model and artists to work on the wonderful business of capturing the human form in various media. I’m a reasonably private person so I like to keep the anonymity level reasonably high, but it does not only work. People are of course on the watch out to protect the group from perceived problems, so they ask questions. Others are just trying to make friends, and so they ask questions too. I just like to be polite and friendly, share the odd joke or remark, but mostly keep my mouth shut and listen to the various small talk that breaks out during breaks. Most of all, I want to get on with the business of drawing.
I went to one on Monday. This time around it was sort of amusing to me at one point when one of the organisers of the group asked me why I’d come down from LA to their small seaside town drawing group and I said I was hiding. I could sense alarm immediately (I can imagine the pictures he might have had in his mind even before I said “hiding”) and so I then went further, by way of reassurance, and said something vague but standard about wanting to get out [...] Click to continue reading this post
When calling to mind the Los Angeles Philharmonic, everyone’s (and all the posters’) focus is on Gustavo Dudamel, (or, the Dude, as I call him), all unruly hair and visible enthusiasm and so forth, and that’s great. He’s an excellent conductor. However, one of the unsung (as far as I know*) visibly spectacular performers of the LA Philharmonic is the excellent principal viola player whose name I do not know [update: see below*] who puts on the most remarkable physical performance every time I go (and presumably those other times too). Actually, the violist who sits next to her is also remarkable, since she manages without being distracted by her neighbour to maintain a very upright and solid, firmly planted, legs wide stance, in part providing a canvas upon which the viola player I first mentioned can splash bright splashes of movement all over the place! She rocks, sways, jerks, and contorts (sometimes even during quiet slow bits)- doing the craziest things with her legs, head, and bow arm, and so much of the time looks like she is about to spectacularly fall off her chair and wipe out at least half the viola section! This is why her colleague right next to her is also remarkable, as she acts as this wonderful un-distractable “straight man” to the physical pyrotechnics helping make them all the more remarkable by contrast. Last night I tried to capture some of the energy of the hyper-energetic viola player in a quick sketch (during [...] Click to continue reading this post
After a long weekend of a two-day meeting of an American Physical Society committee (hosted in LA this time, so I did not have to travel far), I decided last night to go and do a drop-in-and-draw session at an art studio, to clear my mind.
The model was excellent, with a smashing hairdo and good body-awareness that made for interesting poses. I was in the mood to disappear and listen to Hendrix for three hours while focusing on the simple task of representing what was in front of me. So I did.
I’m horribly slow again. Lack of regular practice (on full figures), of course. The good news is that I have been able to hold on to some of the more important foundations that allow me to lay things out, and see forms and shapes. But it does mean that I don’t get to get to some of the finishing processes that I intuitively prepare for in the earlier parts of the drawing.
As you know from many posts of mine on the subject (see e.g. here and here) I actually like incomplete drawings where you can see a lot of the process [...] Click to continue reading this post
I did not get to read the instructions about the games, but pictured are some cards (apparently from about 1830) for a game set. They have images of stars and planets on them, including one planet called Herschel. This is of course the planet to later be called Uranus. It took a while for the planet’s name to be agreed upon.
These are some of the objects from the Doheny Libary’s collection that will be [...] Click to continue reading this post
Don’t forget that on the USC campus on Friday at 4:00pm, we’ll be kicking off the Collecting the Cosmos event! It will be in the Doheny library, and there’ll be a presentation and discussion first, and then a special opening reception for the exhibition. Be sure to get yourself on the waiting list since there’s some chance that you’ll get in even if you have not RSVPed yet. (The image is from the Visions and Voices event site, and includes parts of the artworks – by artists Victor Raphael and Clayton Spada – to be included in the exhibition, so come along and see.)

It is Martin Luther King day today. I noticed something I’d like to share. A team at the USC School of Cinematic arts in collaboration with the Martin Luther King, Jr. Research and Education Institute created an excellent animated mural (for want of a better term) to accompany the famous “I Have a Dream” speech. I recommend checking it out, here. From a USC news article about it, I learned that it:
“… allows viewers to scroll through the speech while learning about its history and context. Viewers can move phrase by phrase, see where King broke away from the written text …”
It is decorated by lovely drawings (which, as you might guess, is of course what caught my eye in the first place) and text and images. It uses a suite of software called Scalar, a platform designed at the Alliance for Networking Visual Culture at the school. It looks rather wonderful actually.
Go and re-live the speech once again, here.

My mum has been visiting for the holidays. For her recent birthday I decided that instead of making a birthday card from a photo of one the roses from my garden (as I usually do) I would make her a drawing/painting of one on a card instead. The paper of the card has a ridged texture and I imagined that this would be an interesting component of the final piece. Using a photo of one of my roses as reference on screen in front of me, I sketched onto the paper [...] Click to continue reading this post
There is always a mixed set of emotions for me when I come to change notebooks. It means that I stop carrying around pages and pages of ideas, impressions, sketches, and other things from the last few months that I can accidentally stumble upon. Instead, I start a whole new blank book that does not connect back to anything. I must fill new pages (which I love doing) that will become those favourites I will look back on. So I always like to start off with a drawing that I’ll like to look back on. It helps set the tone for the pages to come in the many months. (See an earlier post about this matter here.)
Yesterday gave me a nice opportunity. I took my mum (who is visiting for a while) to the beach in Santa Monica and we walked together on the sand for a little while. I then sat on the sand and did a sketch while she continued walking and looking around. My focus was the Santa Monica pier, and I wanted to [...] Click to continue reading this post
Holiday time is upon us, and in this part of it, it is coming up on Christmas time. Really fast, it seems. The semester sort of petered out mid-week for me with the submission of the final grades for my graduate electromagnetism class (everybody did really well… fantastic group of students this year), and one last two hour committee meeting for another of those committees I can’t tell you about. I’ve found some time to think about some physics, and work on a new page for the book, among other things. There’s a panel [...] Click to continue reading this post
Finished the inks and threw some (digital) paints over the lunch group. I think it’s time to move on to another part of The Project. I’ve spent far too long fiddling with the light in this.

Actually, this new tool is pretty old school, and I love it! There are times when I want to have a change of venue while doing rather detailed work for The Project… perhaps go sit in a cafe for a change, instead of at the drawing desk. But when not at the drawing desk, I could not use the lovely large illuminated magnifying glass […] Click to continue reading this post
Well, since yesterday was all about eating here in the USA (Thanksgiving, in case you missed that), I thought I’d share a partially inked panel from The Project, of a meal in progress. I got a bit of quiet time to work on it this evening, while listening to Jimi Hendrix and then Freddie Hubbard. They helped a lot. It is at times like this I wonder what insanity has come over me […] Click to continue reading this post
Sunday saw me spend a bit of relaxing time in the morning at a breakfast bar sketching a colourful pan of tomatoes, apples, and a yellow pepper. I spend ten minutes doing a quick pen and ink outline sketch of all the elements, which was fun and pleasingly simple enough.
But then I decided to lay on some colour and so pulled the sketch into Brushes on […] Click to continue reading this post
It has been a long and tiring week so far and I decided that I needed to withdraw for a little while. So I left campus early and went on a wander downtown. My goal? It is the last day of the worldwide Big Draw month of October (but see below*) aimed at raising awareness of drawing (you may have seen events in your own town – maybe even participated in some), and I’ve been so busy I’ve not done much outdoor on-location drawing this month (not counting subway drawing) and so I thought that I’d get one in on the last day. My own little contribution to the local Big Draw LA, if you will.
Anyway, I considered doing some well-celebrated landmark like one so many of the splendid buildings available (Union Station, Central Library, Eastern Building, Walt Disney Concert Hall…), and as I walked I pointed myself in the direction of some of these, but just after I turned away from the library on Fifth, heading to Pershing square, I saw what I wanted to draw. If you stay on […] Click to continue reading this post
Managed to find a little time over the last few days to lay out, draw, and ink a page in The Project. It has been insanely busy for me, so this is a little bit of a triumph in stealing some time back. It’s actually the same seminar that you saw in earlier posts (here and here). Now it is over. It remains a tradition in our field to give a little round of applause after a talk, which I find rather nice and quaint. It was a pleasure to depict that.
It is a wider view of the room, which meant (aaaargh!) drawing even more faces and bodies than before. Then there’s the challenge of doing them in different states of attention, applauding, with different faces, bodies, states of dress, etc. When I come to paint it I’ll be wanting to pick colors that together communicate the right mood for the panel and for the whole page it is part of, and so forth. It can be daunting to do all those faces, bodies, shirts, feet, and […] Click to continue reading this post
I realized just now that since I set a midterm exam on Monday for the graduate electromagnetism class, and since there’s only one midterm for the class, it really is… midterm. The semester is sort of half over already. And indeed, a glance at my calendar shows this to be more or less true. I’ve mixed feelings about this since on the one hand it is a busy and tiring semester and I’m glad to have it go by, but on the other hand… slow down life! What’s the rush!? Yes, I definitely keep wanting to make sure I stop to smell the flowers, or what’s the point?
The midterm itself (Monday, in class) was fun. Or at least, I found it fun to put together on the weekend. There were no complaints from the students, so I hope that means I got the balance about right. We shall see during class tomorrow, when [...] Click to continue reading this post
I’ve been thinking about the early 20th Century recently, and the development of quantum mechanics, as a result of re-reading Michael Frayn’s play Copenhagen. There’s going to be a staged reading of it tonight at USC, put on by the School of Dramatic Arts, and I’ll be giving an opening address. I sat in a bar late last night over a fine oatmeal stout, thinking a little bit about what I might say in the address, and I expect I’ll put the finishing touches on the brief sketch of ideas while sitting on the subway to work this morning. We shall see. I’ll try to remember to post the text of it here if it turns out to be not entirely dreadful.
I’ve very clear memories of this play, and my first encounter with it. I was lucky to get to go to a special pre-opening performance of it when it debuted in New York (in the year 2000) I and got to meet and talk to Michael Frayn (and if I recall correctly, Claire Tomalin) about the writing of the play at the after-party at Sardi’s – a very interesting conversation it was too. I also (by a happy coincidence) got to sit next to Freeman Dyson during the performance, and was able to glance over occasionally to see the delight on his face at seeing old acquaintances of his brought back to life. (Well, I learned afterwards that this was the reason for the delight…)

I must say that I had fun doing this drawing (click for larger view), and it was a long time coming. After returning from New York I decided that after a lot of tiring travel back and a long day of work the next day that I would keep the momentum from the plane drawings and go and relax and do a drop in and draw at a studio for a few hours.
It has been a long time since I’ve popped into a studio to draw a model and I am happy to say that I was not as frustrated in the end as I thought I might be due to lack of practice. (In fact, it is best to try to enjoy getting done what you can get done, and not get frustrated since that just makes things worse…) I was a bit slow, yes, but was happy that the processes of how I draw best came together readily, and by the [...] Click to continue reading this post
I’m going to admit something maybe a little naughty right now. One of the things I was most looking forward to about the whole New York trip was the plane ride so that I could spend time drawing. It has been a long and busy several weeks into the semester already and that means that I’ve been not getting as regular drawing practice in as I’d like. So the airline downtime (blogged about here and here) is actually rather a welcome activity since I can bring out the sketchbook and draw. I’ve been regularly requiring myself to work directly in ink, so this means no correction of mistakes as one goes along. To proceed in drawing, you incorporate poor decisions about lines you’ve made into the drawing if you can, and move on. It also means that you learn to look more closely and think a bit more about line choices, and what you’re trying to capture.
Anyway, this fellow was sitting on a hydrant on one of the streets bordering [...] Click to continue reading this post
