(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

Since this time I don’t think I’ll be getting the call from the folks at Screen Junkies to talk about this one, I’ll do a quick post on my thoughts while they are still fresh. (There are no real spoilers in what follows, but if like me you like to know as little as possible about a film before going to see it, forming your own opinion before having to see the film filtered through those of others, do wait until you’ve seen it before reading beyond the second paragraph.)
I enjoyed the film very much. As a piece of human drama, it was a great story to tell, and frankly it does fill me with dismay that few people seem to know the story, so I am glad it is getting mainstream attention. It was done extremely well, in terms of standard things like all the acting performances (more or less), photography, and the overall tone of the direction. Given the subject matter – its social and historical importance – this was a beyond the ordinary human drama well told. I enjoyed it.
But it missed an opportunity to not just be “beyond the ordinary” but truly exceptional and ground breaking. All we needed was about 5 or so minutes of extra screen time to achieve this. I’m talking about the ironic fact that Interstellar, which is I remind you a science fiction film (which many scientists […] Click to continue reading this post

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
Sorry about the slow posting this week. It has been rather a busy time the last several days, with all sorts of deadlines and other things taking up lots of time. This includes things like being part of a shooting of a new TV show, writing and giving a midterm to my graduate electromagnetism class, preparing a bunch of documents for my own once-every-3-years evaluation (almost forgot to do that one until the last day!), and so on and so forth.
Well, the other thing I forgot to do is announce that I’ll be doing the local Sunday Assembly sermon (for want of a better word) this coming Sunday. I’ve just taken a step aside from writing it to tell you about it. You’ll have maybe heard of Sunday Assembly since it has been featured a lot in the news as a secular alternative (or supplement) to a Sunday Church gathering, in many cities around the world (more here). Instead of a sermon they have someone come along and talk about a topic, and they cover a lot of interesting topics. They sound like a great bunch of people to hang out with, and I strongly [..] Click to continue reading this post
The Nobel Prize in Physics this year is to Isamu Akasaki, Hiroshi Amano, and Shuji Nakamura, for the blue LED. Seems like a small thing, but it is hugely important for a lot of reasons, not the least of which is the issue of producing energy efficient light sources for everyday use. We’re all benefitting from this recent discovery (how to actually make them!) already.
See the Nobel Press release here, and Congratulations to the winners!

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!*

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
You may recall that back in June I had a chat with Hal Rudnick over at Screen Junkies about science and time travel in various movies (including the recent “X-Men: Days of Future Past”). It was a lot of fun, and people seemed to like it a lot. Well, some good news: On Tuesday we recorded (along with my Biophysicist colleague Moh El-Naggar) another chat for Screen Junkies, this time talking a bit about the fun movie “Guardians of the Galaxy”! Again, a lot of fun was had… I wish you could hear all of the science (and more) that we went into, but rest assured that they* did a great job of capturing some of it in this eight-minute episode. Have a look. (Embed below the more-click):

So 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
In case you missed it, Maryam Mirzakhani has been awarded the Fields Medal! This is regarded as the most prestigious prize in mathematics. Here’s a Guardian article covering it at a general level, and here is the page on all the award winners, with more detail on each, at the International Mathematical Union website. The reason this is a big deal (and why it is newsworthy) is because it is the first time the prize has been awarded to a woman. In a world where, despite the number of excellent women mathematicians out there, there is still a perception problem in the general populace about who (or more to the point, what gender) is associated with achievement in mathematics, it is important to note and celebrate such landmarks.
I also note that one of the other 2014 awardees, Artur Avila, is from Brazil! While not covered as much in the press as far as I can see, this is another big […] Click to continue reading this post
I think the people at LA Metro were trying to go for all of the visual science tropes in one cliché-filled glance! I’m a big fan of LA Metro, as you know from several posts about it here, so don’t misunderstand my poking fun at their ad I spotted on a bus stop bench. I think it is to do with helpful apps for your phone – presumably they help you use the system more easily, because of…science? More generally, I’d love to believe that people will take the train more because scientists are involved in designing the logistics, but there’s so much evidence against this on both counts, like having the Blue line and the Expo line – that share the same main platform – both boast BLUE as their colours. But put that all aside for now, and let’s simply count off all the sure-fire imagery that will […] Click to continue reading this post
It 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! So Jalen Langie (the daughter, amusingly wearing a lab coat) gets to be […] Click to continue reading this post
I’m sitting on the bus, on my way to the LA Times Festival of Books. I’ve opened my notebook to maybe sketch a face or two, but then I spot an algebraic error on a page from a few days ago, so I set about correcting it….(you know, either for those historians who will argue about my intentions while poring over these once-lost manuscripts…. Or more likely for me in a few weeks, likely to get confused by my own blunder-in-haste with a kindergarten level variation.)
A bearded fellow had boarded the bus and sat next to me while I was doing this. He eventually glances my way, then away, then he does a double take. I’ve been watching him out of the corner of my eye. He starts to speak to me.
Calc or Trig?
Calc or trig?
What are you studying?
I’m not…studying. It is my research.
Silence from him for a few beats, then:
Charged black holes.
I should say at this point that I get this a lot. No matter who I meet out there in the random world, or what they see me writing, the assumption is always that I am taking a class in high school mathematics. Why is that? People, at least guess for some of the time that I might be at least teaching it, even if you can’t imagine people doing research in this area. The grey hairs in my beard are a guide to your assumptions.
Another gripe: if you see someone writing words, and want to engage them in conversation about it, you don’t assume they are practicing the basic structures… Imagine the analogous exchange: Are you practicing joined-up writing madam, or spelling? Neither, I’m writing poetry.
Anyway, back to the conversation. So, as you recall, I said Charged black […] Click to continue reading this post
Thursday’s event at the Natural History Museum went very well. There was a great turnout, and the audience was very enthusiastic. As you can see from the photos*, there were two fierce-looking large dinosaurs in attendance in the audience, but it did not have any effect on the overall time-keeping, and the lectures ran over the allotted time quite a bit.
But people had fun, and the museum staff were very kind and flexible, so that’s ok. I actually learned a lot from Ed Krupp’s talk about the astronomy and astronomical objects along the Silk Road from the Far East to the Middle East especially. Laura Danly gave a talk that was mostly a detailed history the Internet including at least three internet cat videos as illustration (an emphasis that I found unexpected, I’ll admit, since I was expecting more about contemporary astronomy). It was certainly a modern perspective on the Silk Road, as we promised the audience, and it seemed to go down well. The observation opportunity that Laura arranged outside (with the telescopes that were set up in the new gardens) was also well received. Jupiter and its […] Click to continue reading this post
