Happy Centennial, General Relativity!

general_relativity_centennial_kip_thorne(Click for larger view.) Well, I’ve already mentioned why today is such an important day in the history of human thought – One Hundred years of Certitude was the title of the post I used, in talking about the 100th Anniversary (today) of Einstein completing the final equations of General Relativity – and our celebration of it back last Friday went very well indeed. Today on NPR Adam Frank did an excellent job expanding on things a bit, so have a listen here if you like.

As you might recall me saying, I was keen to note and celebrate not just what GR means for science, but for the broader culture too, and two of the highlights of the day were examples of that. The photo above is of Kip Thorne talking about the science (solid General Relativity coupled with some speculative ideas rooted in General Relativity) of the film Interstellar, which as you know […] Click to continue reading this post

One Hundred Years of Certitude

Einstein_CentennialSince the early Summer I’ve been working (with the help of several people at USC*) toward a big event next Friday: A celebration of 100 years since Einstein formulated the field equations of General Relativity, a theory which is one of the top one or few (depending upon who you argue with over beers about this) scientific achievements in the history of human thought. The event is a collaboration between the USC Harman Academy of Polymathic Study and the LAIH, which I co-direct. I chose the title of this post since (putting aside the obvious desire to resonate with a certain great work of literature) this remarkable scientific framework has proven to be a remarkably robust and accurate model of how our universe’s gravity actually works in every area it has been tested with experiment and observation**. Despite being all about bizarre things like warped spacetime, slowing down time, and so forth, which most people think is to do only with science fiction. (And yes, you probably test it every day through your […] Click to continue reading this post

It’s Time

delorean_sketchOk, So I’ve finished prepping my presentation of detailed recipes for how to make time machines. (Sorry, but it does not involve any of the elements depicted in the sketch above.) It is for a special event tonight celebrating the fact that this is the day Marty McFly came forward in time to in Back to the Future II. The question is: Should I really be telling people how to do this? Yikes. ;)

Ok, time to get into my flying car and head off to teach…

PBS Shoot Fun

pbs_shoot_selfieMore adventures in communicating the awesomeness of physics! Yesterday I spent a gruelling seven hours in the sun talking about the development of various ideas in physics over the centuries for a new show (to air next year) on PBS. Interestingly, we did all of this at a spot that, in less dry times, would have been underwater. It was up at lake Piru, which, due to the drought, is far below capacity. You can see this by going to google maps, looking at the representation of its shape on the map, and then clicking the satellite picture overlay to see the much changed (and reduced) shape in recent times.

There’s an impressive dam at one end of the lake/reservoir, and I will admit that I did not resist the temptation to pull over, look at a nice view of it from the road on the way home, and say out loud “daaayuum”. An offering to the god Pun, you see.


Turns out that there’s a wide range of wildlife, large and small, trudging around on the […] Click to continue reading this post

Marginal Activity

The last couple of weeks have seen me fiddling with another important task for the book: rethinking the page dimensions. This gets me into things like crop points, safe areas, bleeds, and so forth. It is sort of crucial that I worry about this now and not later because for the kind of book I am working on, every single page is a unique self contained entity that must be designed individually, while at the same time each page still depends on all the other pages to be just right. So a change in page dimensions is a huge deal in the process. This is not like writing large blocks of prose in the form of chapters and paragraphs, where the page dimensions are less crucial since your words will just flow and re-flow automatically to adjust to the new shape of container (the page), newly spilling over to the next page if need be. Instead, graphic elements -the drawings- all must work together on a number of different levels on the page, their relative positioning being crucial, and any text that is present must also respect that layout… In fact, text is really just another graphic element on the page, and is not as malleable as it is in a prose book.

sample_exp_iv (Random sample from a story I’ve just completed the roughs for in the new dimensions. You can see the red guide lines I work to to make sure that the page comes out fine at the printer, the inner being the “safe area” beyond which you don’t put any crucial elements like text in case they are cut off. The outer is the line where the page should end. Some of my pages have “bleeds” which means the art will flow all the way past that outer line so that when cropped that part of the page is covered entirely with art instead of it stopping due to a panel border…)

I say all this because it is an issue close to my heart right now. Back when I did all the art for the prototype story (some years ago now), and right up to last year, I did not yet have a publisher for the book, so therefore of course no idea what the final page dimensions might be. Different publishers have different favourites, print capabilities, and so forth. So I made the best decision […] Click to continue reading this post

Tales from the Industry XXXXI – Puppet Black Hole

Yeah. Not sure how to best title this post or fully explain the picture [edit: Picture taken down temporarily until the show is ready to be promoted]. Let’s just say that I spent a bit of this afternoon explaining some of the science of the Large Hadron Collider to a bright orange puppet that was determined to not believe whatever I told him/it. It was fun, and was done to camera at Los Angeles Center Studios downtown. (I was actually speaking about things that intersect with the subject of yesterday’s post, if you’re interested.) It is for a new show on a channel that I can’t mention yet*, and I’ll let you know as soon as I know what the air date is, etc.

Well, one more thing, in support of the old “It’s a small world after all” saying. I noticed from the call sheet that this morning they were shooting a fun segment that was hosted by my friend Hal Rudnick the host of Screen Junkies! (Have a look at some of the science-meets-movies things we’ve done together here, here and here.) Also, a friend I’d not seen in […] Click to continue reading this post

Beyond the Battling Babes

Screen Shot 2015-04-16 at 14.03.58The recent Babe War (Food Babe vs Science Babe) that probably touched your inbox or news feed is a great opportunity to think about a broader issue: the changing faces of science communication. I spoke about this with LA Times science writer Eryn Brown who wrote an excellent article about it that appears today. (Picture (Mark Boster/Los Angeles Times) and headline are from the article’s online version.)

(By the way, due to space issues, a lot of what we spoke about did not make it to the article (at least not in the form of quotes), including: […] Click to continue reading this post

Tales from the Industry XXXX – Relative

relativity_shoot_1(Click images for larger view.)
Last Tuesday was a bit unusual. I’ve been chatting for a while with the people making a new BBC/PBS(NOVA) special in celebration of it being 100 years since Einstein’s presentation of the field equations of General Relativity, and that was the day we’d arranged to have an interview of me saying a few ideas to camera, and also doing a demo or two for fun. It was a very tight schedule, and a lot had to be arranged since one of the demos involved me sitting on the back of a flat bed truck at a desk (apparently in an office), looking up and explaining something, only to have the camera reveal the larger context in which the conversation was taking place. Well, the office set and desk were abandoned for various reasons, and then we got held up for almost two hours because the campus safety people turned out to have been confused (?) by the director’s careful notes in advance of the shoot and did not realise that the flatbed truck with me and the furniture and the cameraman would actually be moving. Even though it was intended to move at only a snail’s pace, it violates their safety rules to not have everything strapped down with safety harnesses. It qualifies as a “stunt”, and they were not expecting one. So there was a lot of back and forth over walkie talkies and in person and so forth, and persons with little golf carts coming and going, until some of the crew dashed off to Autozone to buy several cargo straps that, after application, seemed to make everyone happy.

I climbed up and allowed myself to be strapped in too. Before it all got started I asked about how exactly I was to unstrap myself if for some reason the flatbed […] Click to continue reading this post

Layout Design

Rough layout design. Text suppressed because… spoilers. Feel free to supply your own dialogue… share it here if you like!


(Click image for larger view.) In case you’re wondering, I’m trying here and there to find a bit of time to do a bit of rough (but less rough than last pass) layout design for the book. Sample above. This helps me check that all the flow, layout, pace, and transitions are […] 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

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

A Contract With…

Good News Everyone!


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

The Universe Lives!

(Seems a highly appropriate title to use when up at 4:00am listening to the excellent violent wind and rain storm that’s going on outside.) This is mostly a note for fans of the show The Universe, on the History channel, or H2, and channels by other names internationally. I just wanted to say that the show is going to carry on, with a new season coming out early next year!

I mention this because it looked for a while (at least a few times) like there wouldn’t be another season (after a solid 7 or 8 seasons over as many years), and then at the last minute they greenlit that short season that aired earlier this year with the subtitle “Ancient Mysteries Explained” or something worrying like that (because it sounds a lot like the “Ancient Aliens” show which, well, I’d rather it did not sound anything like…) Then it was not clear again whether that was just a last hurrah or not…

Well, it was not, since we’ve been shooting for several episodes this last month or so! Looks like there will be at least a short season coming, with the same subtitle. I’ve done some work on a few segments that will appear in two or three episodes. They wanted me to do more but I had a rather busy period coming up and so declined to do any more shooting days after November, so I’ll be somewhat fleeting in my appearances, but hope that the physics I did get to talk about is clear and interesting – assuming they use those bits at all (you can never tell).

My favourite day was when we were out at Zuma Beach, which I think I mentioned in a short post a while back. The episode focuses on contrasts between Astronomy and Astrology, which is certainly a good topic! I came up with a fun analogy with which to explain a certain idea and we enlisted a group […] Click to continue reading this post

Look Up In the Sky…!

graduate_electromagnetism_class_sky_watchingYesterday’s graduate class in electromagnetism had a bit of extra fun. We did a particular computation in some detail, and arrived at a pair of results. We thought about the main features of the equations we’d derived and I then asked the class if they could think of an example. An example with those equations essentially written all over it. It was the sky. Not just the blueness of the sky (for which the result supplies a partial answer) but the pattern of blueness on the sky, especially when looking through your polarised sunglasses. (You know how you tilt your head when wearing them and you can darken or lighten the sky a bit? Well, that effect is way more effective if you are looking in a direction at right angles to the sun as opposed to either toward or away from the sun.)

So I took the class outside to gaze upon the sky in person, rather than just sit and talk about it. Actually, a little bit of knowledge about the pattern of blue in the sky is useful in a lot of ways. For example it is amusing to me to see how often architects and their artist collaborators get the sky wrong in renderings of […] Click to continue reading this post

Interstellar Thoughts

After emerging from a spectacular 70mm viewing of Interstellar at the Arclight Dome last night, I was grinning from ear to ear, which is unusual these days after seeing a film in this subject area (science fiction, space travel, the future of humanity, etc). (And by science fiction here I mean proper science fiction, not space opera or space adventure. There’s a lot of that and some of it is fun and makes me grin too, like this Summer’s Guardians of the Galaxy. But that’s not at all the same sort of thing.)

I’m not going to go into any details, since I am very tired of the practice of talking about films to the extent that you say so much of what happens that it is impossible for someone to enjoy watching the film unfold in front of them without knowing what comes next, the way I like my films best. So I’m not going to ruin things for you.

Everybody keeps asking me “what did you think of the science?” since they know that there’s a lot of stuff in there that relates to my subject area and interests. Many seem to want me to pronounce on what’s “good” and whats “bad” about the science, as though I’ve (like many scientists in the public sphere seem to have done) elected myself some sort of guardian of scientific ideas. Let me say two things. The first is that this is a science fiction film, not a science documentary. I’m already hearing all sort of humourless declarations about this and that and the other being wrong and how shameful it is, as happened with Gravity last year. Done right, such discussions can be an opportunity to teach a bit about science ideas, but most often it just comes across as being a smartass, which is a bit tedious, and leads me to my second point.

The second point is something I say a lot and needs to be said a lot more: Scientists don’t own science and its concepts and ideas. We should be careful […] Click to continue reading this post

I Dare!

sunday_assembly_3(Click photos* for larger view)

Yes. I dare to show equations during public lectures. There’ll be equations in my book too. If we do not show the tools we use, how can we give a complete picture of how science works? If we keep hiding the mathematics, won’t people be even more afraid of this terrifying horror we are “protecting” them from?

I started my Sunday Assembly talk reflecting upon the fact that next year will make 100 years after Einstein published one of the most beautiful and far-reaching scientific works in history, General Relativity, describing how gravity works. In the first 30 seconds of the talk, I put up the equations. Just because they deserve to be seen, and to drive home the point that its not just a bunch of words, but an actual method of computation, that allows you to do quantitative science about the largest physical object we know of – the entire universe!


It was a great audience, who seemed to enjoy the 20 minute talk as part of […] Click to continue reading this post

Secrets of the Earth

Screen Shot 2014-10-20 at 1.17.23 PMMy guess is that most of you don’t know that you can find original science programming on the Weather Channel. (Just like, say, 8 years ago most of you would not have been tuning to the History Channel for original science programming about how the Universe works, but many of you know better – (and thanks for watching The Universe!)) Well, this week one of the series that they have that does do some science, Secrets of the Earth, comes back for a new season.

I made some contributions to several of the episodes, and I think I appear in at least two of them as a guest. So look at the whole season for some tasty bits of science about the world around you, and if inclined to, do […] Click to continue reading this post

Save “Krulwich Wonders”!

As readers of this blog who appreciate the idea of putting science into the daily routine for a balanced diet, of mixing in sketches here and there, of good humour and a wondering eye on the world…. you’ll agree with me that we need to raise our voices and call out to NPR to Save “Krulwich Wonders”. According to Robert Krulwich, they are planning to cancel his blog as part of cost-cutting… this would be a big blow for the (always in danger) mission to improve the public understanding of science. Many suggestions are in the comments to that post I liked above, so feel free to read them and follow the ones that make sense to you! [Update: I’ve put a hashtag #savewonderNPR into the accompanying tweet of this post, so feel free to use that in your own raising awareness efforts on this…]

Act fast to let your voice be heard. The axe is on its way down!*

Dusting off Last Spring’s Excitement

There has been quite a bit of discussion of the realisation that the exciting announcement made by the BICEP2 experiment back in March (see my post here) was based on erroneous analysis. (In brief, various people began to realise that most, if not all, of what they observed could be explained in terms of something more mundane than quantum spacetime fluctuations in the ultra-early universe – the subtle effects of galactic dust. A recent announcement by another experiment, the Planck team, have quantified that a lot.)

While there has been a bit of press coverage of the more sober realisations (see a nice June post on NPR’s blog here), it is (as with previous such cases) nowhere near as high profile as the initial media blitz of March, for better or worse. I think that “worse” might be the case here, since it is important to communicate to the public (in a healthy way) that science is an ongoing process of discovery, verification, and checking and re-checking by various independent teams and individuals. It is a collective effort, with many voices and the decentralised ever-sceptical scientific process itself, however long it takes, ultimately building and broadening the knowledge base. This self-checking by the community, this reliance on independent confirmation of […] Click to continue reading this post

Meanwhile, Somewhere Down South…

hotel_down_south_1st_Sept_2014So while at a hotel somewhere down South for a few days (pen and watercolour pencil sketch on the right), I finally found time to sit and read Graham Farmelo’s book “The Strangest Man”, a biography of Dirac. (It has a longer subtitle as well, but the book is way over in the next room far from my cosy spot…) You may know from reading here (or maybe even have guessed) that if I were to list a few of my favourite 20th century physicists, in terms of the work they did and their approach and temperament, Dirac would be a strong contender for being at the top of the list. I am not a fan of the loudmouth and limelight-seeking school of doing physics that seems all so popular, and I much prefer the approach of quietly chipping away at interesting (not always fashionable) problems to see what might turn up, guided by a mixture of physical intuition, aesthetics, and a bit of pattern-spotting. It works, as Dirac showed time and again.

I’ve read a lot about Dirac over the years, and was, especially in view of the title of the book, a little wary of reading the book when I got it four years ago, as I am not a fan of going for the “weren’t they weird?” approach to biographies of scientists since they serve too […] Click to continue reading this post

Young Author Meeting!

20140413-110946.jpgIt is nice to see the variety of authors at a book fair event like this one, and it’s great to see people’s enthusiasm about meeting people who’ve written works they’ve spent a lot of time with. The long lines for signings are remarkable! As you might guess, I’m very much a supporter of the unsung authors doing good work in their own small way, not anywhere near the spotlight. An interesting booth caught my notice as I was wandering… The word “science” caught my eye. Seems that a mother and daughter team wrote a science book to engage children to become involved in science… Hurrah!

Under Silk Road Skies

I’m doing a disturbing amount of speechifyin’ this month. One of the occasions is tomorrow, and is open to the general public. Have you been to the Natural History Museum’s “Traveling the Silk Road” exhibition yet? I went to have a look a couple of days ago and it is rather nice. I recommend it. There are even live silk worms!

Not Struck…

…by lightning or anything. Yay.


It was fun! (See previous post for what I’m talking about.) The audience seemed to like it. I got to explain that being curious and doing experiments and forming hypotheses is somehow preferable (to some) to sitting back and saying “God did it”, and that there are a lot of nice side effects of that curiosity. (You know, increased food supply, improved medicine, better communications, travel, overall quality of life, and so forth…) We even got to talk a tiny bit about physics (somehow I got on to neutrinos…. not sure why, but then… why not?).

Heaven Help Us

Well it is 6:30pm. It was my plan to take a nap this late afternoon (maybe early evening) but I’m not going to do that anymore. Why? Well turns out I’m appearing in a show this evening. It starts at midnight so I’m a little afraid that I might just sleep all the way through, wake up tomorrow morning and so miss my spot. So while the sleep would do me some good in order to be up so late, and functioning, I think I’ll skip it.

What’s the show? Well it’s a show on stage put on by some of the Upright Citizens Brigade. They asked me to appear as a guest – not as a character, but actually as myself, a scientist. It’ll be in front of a live audience, although they will be taping it later possible broadcast. You know how it goes with me – I especially like an opportunity to put some science out there here it is not expected so this is right up my alley. My understanding is that it’s a comedy […] Click to continue reading this post
