Sometimes there is Smoke without Fire

…Or at least, not always the fire you’re looking for. So, as suspected for several months now, the signal seen by the BICEP2 experiment and dubbed “a smoking gun” type of direct evidence for cosmic inflation (for which we have lots of strongly suggestive indirect evidence, by the way) is likely an artefact of the effects of galactic dust. I spoke about this in a post a while back, so I won’t repeat myself here. What everyone has been waiting for has been the results of a joint analysis between the BICEP2 people and the ESA’s Planck mission. The Planck satellite, you may recall from reading here or elsewhere, is also designed toPlanck_view_of_BICEP2_field_node_full_image_2 carefully study the polarisation of the cosmic microwave background (the earliest light to shine in the universe), and so can (through thorough analysis of the effects of dust that it has measured independently) help rule in or out whether there is a signal. Planck studies essentially the whole sky, not just the patch that BICEP2 was carefully looking at, and one of Click to continue reading this post →

LAIH Field Trip: The Natural History Museum!

LAIH_NHM_Field_Trip_3On Friday the Los Angeles Institute for the Humanities went on another field trip. This time we went to the Natural History Museum. (Click the image for a larger panorama from one of the dinosaur halls.) If you’ve not been there for a while, this is not the museum you remember. It has been transformed, under the leadership of Jane Pisano (President and Director of the Museum, who gave us a splendid talk over lunch), adding several new spaces, a special garden, and new foci in its programming (such as special displays and research programs highlighting urban ecosystems – featuring coyotes, rats, squirrels, possums, Cooper’s hawks, doves, skunks, parrots, etc., (basically my back garden on a typical day, as you know from this blog), along with snakes, bedbugs, termites… The Nature all around us in the city of Los Angeles – fascinating actually.)

We had a tour of some of the spaces, breaking up into two groups (there were around 40 of us) and taking turns on two mini-tours (as we did for the Clark Library in December), one looking at the new dinosaur halls, the other the space dedicated to the urban environments I mentioned above. We learned a lot from our guides about what’s going on in the forefront of research in both Click to continue reading this post →

The Visitors

jim_gates_talk_usc_26_jan_2015_smallYesterday I sneaked on to campus for a few hours. I’m on family leave (as I mentioned earlier) and so I’ve not been going to campus unless I more or less have to. Yesterday was one of those days that I decided was a visit day and so visit I did. I went to say hi to a visitor to the Mathematics Department, Sylvester James Gates Jr., an old friend who I’ve known for many years. He was giving the CAMS (Center for Applied Mathematical Sciences) distinguished lecture with the title “How Attempting To Answer A Physics Question Led Me to Graph Theory, Error-Correcting Codes, Coxeter Algebras, and Algebraic Geometry”. You can see him in action in the picture above.

I was able to visit with Jim for a while (lunch with him and CAMS director Susan Friedlander), and then hear the talk, which was very interesting. I wish he’d had time to say more on all the connections he mentioned in the title, but what he did explain sounded rather interesting. It is all about the long unsolved problem of finding certain kinds of (unconstrained, off-shell) representations of extended supersymmetry. (Supersymmetry is, you may know, a symmetry that Click to continue reading this post →

In Print…!

graphic_novel_event_postcard_picture_ofHere’s the postcard they made to advertise the event of tomorrow (Tuesday)*. I’m pleased with how the design worked out, and I’m extra pleased about one important thing. This is the first time that any of my graphical work for the book has been printed professionally in any form on paper, and I am pleased to see that the pdf that I output actually properly gives the colours I’ve been working with on screen. There’s always been this nagging background worry (especially after the struggles I had to do to get the right output from my home printers) that somehow it would all be terribly wrong… that the colours would Click to continue reading this post →

Experiments with Colour

Well, that was interesting! I got a hankering to experiment with pastels the other day. I am not sure why. Then I remembered that I had a similar urge some years ago but had not got past the phase of actually investing in a few bits of equipment. So I dug them out and found a bit of time to experiment. pastel_experiment_18_jan_2015_small It is not a medium I’ve really done anything in before and I have a feeling it is a good additional way of exploring technique, and feeling out colour design for parts of the book later on. Who knows? Anyway, all I know is that without my regular subway sketches and so forth, I’m likely to get very rusty, so I need drawing practice whenever I can get a moment between my childcare duties. This was an excuse to get some while trying something new. I can report that it is a lot of fun, and will likely be useful later on… It is a great compliment to the colour I use in my sketchbook: Mostly watercolour pencil (flowed on the page with water brush), and occasionally just coloured ink pens. See e.g. here and here.

(What you see is unfinished – I don’t know if I will finish it. The lady is from a photo in a magazine ad. These are pastel pencils as opposed to raw pastels.)

LAIH Luncheon – Ramiro Gomez

Yesterday’s Luncheon at the Los Angeles Institute for the Humanities, the first of the year, was another excellent one (even though it was a bit more compact than I’d have liked). We caught up with each other and discussed what’s been happening with over the holiday season, and then had the artist Ramiro Gomez give a fantastic talk (“Luxury, Interrupted: Art Interventions for Social Change”) about his work in highlighting the hidden people of Los Angeles – those cleaners, caregivers, gardeners and others who help make the city tick along, but who are treated as invisible by most.

A Special Graphic Novel Panel!

graphic_novel_event_postcardI’ll be on family leave this semester (because… see here), so that means I’ll be intensely busy with other matters most of the time, and will be doing a lot less in the areas of teaching, events, committees, etc. But there will be some things here and there, including things that I’d promised to do before I knew I’d be taking leave. One of them is a discussion on graphic novels for the Harman Academy of Polymathic Study here at USC. (While sitting up bleary-eyed with a very small person in the wee hours of Monday morning I designed the graphics for the postcard they will use for advertising the event. They kindly asked me if some samples of my work could be used, and so the graphic above is what I came up with (they added the logos and event info), made from parts of pages of the work-in-progress book.)

In various ways, the graphic novel is a nice example of the confluence of lots of disciplines and different modes of communication, and as such is a good “polymathic” topic to discuss with the students of the academy (part of the point of the enterprise is for them to learn about how going beyond the narrow constraints of subject or discipline can be of tremendous value, so they study people and creative endeavours that have benefited from that approach – see their website for more). I’ll be joined on the panel by Professor Henry Jenkins (from the Schools of Communication, Cinematic Arts, and Education), and Professor Dana Johnson (from the Department of English), both of whom are real experts in the graphic novel – they are involved in teaching the form, and Click to continue reading this post →

Time to Plan…

Happy New Year! So, it is the second of January. You’ve spent all of the day yesterday recovering from the euphoria (and perhaps revelry) of New Year’s Eve, and so today it is time for the traditional next thing on the new calendar: Planning what you’ll do next New Year’s Eve, of course!

acp_stillBefore doing that however, if you are a research physicist, I’d like to invite you to consider doing something else: Plan your Summer research travel. What I am really trying to do is to make you aware that the end of this month is the deadline for applying to attend the Aspen Center for Physics during some period inside the Summer operating dates Memorial Day (in May) to around Labor Day (September). Now, a lot of people (too many, in my and the opinion of others who care about the ACP) just assume that the place is not for them, for a number of reasons that are really not good ones. So let me address one or two quickly right now.

First, it is not an old boy’s country club. It is for everyone, working in all* fields of physics. Don’t apply and you have zero chance of getting in. Apply and there is Click to continue reading this post →

A Contract With…

Good News Everyone!

contract_sign

The other day I put my signature on a contract to publish The Book!! Some of you might know about my somewhat unusual book project. It is a graphic book, written and drawn by me, all about science. Please tell your friends about it, especially the ones who think that the standard popular science book is not for them. This is very much not the standard popular science book, precisely because I want to broaden the range of people who read about science. The graphic book form has been stunningly underused in my field (physics) and I want that to change.

I used to say “graphic novel style book”, but because of the (well known) problematic naming convention for the form, I’m trying to stay away from that term, because people get confused about what the book is. (Not a novel, for example.) Anyway, it is a highly unusual project that I’ve been excited about for some time, and blogging about from time to time. The last year has seen me doing less on production and more on trying to explore the publishing world to get it in print. (I really do mean printed on actual paper, or I’d have explored other options by now: The self-publishing world has matured interestingly, I’ve discovered in my researches.)

That venture into the world of dealing with publishers turned out to be a huge adventure I ought to write a book about… All I will say here is beware of pitching too original an idea to traditional publishing people. If they can’t Click to continue reading this post →

New Live Model!

Sorry I’ve been quiet here the last week. I was busy with helping complete the acquisition of a new drawing subject! Within 24 hours of said acquisition, I found a few minutes to do a quick pencil sketch of him (as it turned out) in my notebook, through my profound lack-of-sleep fog. (I did a little bit of extra chiaroscuro finish work on it later on.)
