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

Outstanding in Their Fields…

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

Honest Time Travel?

On Tuesday I hung out with some of the Screen Junkies folks who you may know from the hilarious “Honest Movie Trailers” web series (seriously, if you’ve not seen any of them, please go right now and have a look). We had a fun chat about time travel in movies, and presenter Hal Rudnick and I bonded over various movies old and new. The final version of the show is up on YouTube (embed below), and I’m bummed that I did not get to meet the other guest, Christina Heinlein (JPL), who seems fun – and is a descendant of, yes, that Heinlein. I love the idea that she works at JPL, helping make possible the space exploration that Robert Heinlein helped inspire us all about in his writing. Anyway, enjoy the short piece (I wish you could see a bunch of the other material too… we really had a great chat about the ins and outs of time travel, but a lot of it inevitably ended up not making the cut…)

I could not resist talking about my view of this (perhaps growing) trend of using time travel as a means of resetting movie franchises (see Star Trek, X-Men…). It’s a great way of repairing writing and other filmmaking wrong turns. Feel free to imagine your own version of this – Star Wars anyone? Another pass at […] Click to continue reading this post

Metro Goes for All the Science Tropes

science_metro_poster 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

A Monday Interview

On Monday 28th April at 8 PM Eastern time (5 PM Pacific) I’ll take part in a live radio interview that you might want to listen to, on a show called Alpha Centauri and Beyond. I guess I’m in the “Beyond” bit? I don’t really know anything about the show except that they like to bring people on to discuss ideas, and when I get a call to come and help sprinkle a bit of science, you know I’m likely to say yes if I can spare the time.

You can see a link to the details here, and you can listen online. As you can see it is advertised as being about me explaining string theory. Well of course that billing is nothing to do with me – I can’t hope to explain any complicated subject like that in the time available – but if asked I will do my best to try and motivate some of the ideas behind the subject. I hope it will be a fun interview and that […] Click to continue reading this post

Discovery Clarification

[Update: Over the months following the announcement, doubt was cast over exactly what BICEP2 saw, and now it seems that the signal announced by BICEP2 is consistent with polarisation produced by galactic dust. See here.]

I’m actually in hiding and silence for a week. It is Spring Break and I have locked myself away in a seaside town to do some writing, as I did last year. But I must break my silence for a little while. Why? Well there’s been a really great announcement in physics today and while being very happy that it is getting a lot of press attention – and it should since the result is very important and exciting – I’ve been stunned by how confusingly it has been reported in several news reports. So I thought I’d say a few things that might help.

But first, let me acknowledge that there’s a ton of coverage out there and so I don’t need to point to any press articles. I will just point to the press release of the BICEP2 collaboration (yes, that’s what they’re called) here, and urge you once you’ve read that to follow the link within to the wealth of data (images, text, graphs, diagrams) that they provide. It’s fantastically comprehensive, so knock yourself out. The paper is here.

I keep hearing reports saying things like “Scientists have proved the Big Bang”. No. The Big Bang, while an exciting and important result for modern cosmology, is very old news. (You can tell since there’s even a TV comedy named after it.) This is not really about the Big Bang. This is about Inflation, the mechanism that made the universe expand rapidly from super-tiny scales to more macroscopic scales in fractions of a second. (I’ll say more about the super-tiny below).

I also hear (slightly more nuanced) reports about this being the first confirmation of Inflation. That’s a point we can argue about, but I’d say that’s not true either. We’ve had other strong clues that Inflation is correct. One of the key things that pops out of inflation is that it flattens out the curvature of universe a lot, and the various observations that have been made about the Cosmic Microwave Background over the years (the CMB is that radiation left over from when the universe was very young (about 380,000 years old – remember the universe is just under 14 million years old!)) have shown us that the universes is remarkably flat. Another previous exciting result in modern cosmology. Today’s result isn’t the first evidence.

So what is today’s exciting news about then? The clue to the correct […] Click to continue reading this post

No, That’s the Other Guy…

sam_jackson_tvNo, I’m not Neil deGrasse Tyson. Yes, we both talk about science on TV. Yes, we both happen to be black… but no, we are not the same guy. Also: No, I am not Jim Gates. He also sometimes shows up on TV talking about physics, and he is also black.. but no, he isn’t either me (Clifford) or Neil… He’s Jim.

This attempt at humour is inspired (in part) by real conversations I’ve had (less so in recent years, thank goodness – people are maybe better about googling first?). But mostly it is inspired by this (familiar) sad, funny, and stunningly awkward conversation from Monday* (the first 2 minutes 10 seconds): […] Click to continue reading this post

Summing Numbers in a Small World

So here’s a slightly weird thing. So there’s been all this excitement over the web about the old old “shocker” that the sum of the positive integers is -1/12. You know, not even an integer, and not even positive. Apparently there have been articles in the New York Times and Slate and goodness knows where else… and I’ve been ignoring it all since I’m tired of what it often leads to: People wilfully using it as a device to manipulate people’s ignorance about subtleties with infinite processes to make the tired point that string theory is somehow wrong since it is based on “funny math”. I called Lawrence Krauss (who should have known better) out about it some years ago when he did that at an event I happened to attend. It’s a bit tedious, not the least because it is actually part of a wonderful field of mathematics that can get misrepresented, and of course because it has nothing to do with string theory.

So I ignored it all. Then some students in my class asked me about it. And I explained why it is interesting and so forth… Then I carried on ignoring it all.

Then a day or two ago a mathematician colleague emailed me to ask what […] Click to continue reading this post

Collecting the Cosmos

i_2014_01_24_CollectCosmos_150x200Don’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.) The event description says, in part: […] Click to continue reading this post

The Universe Lives!

universe_shoot_16_01_2014Many people have been asking me whether the show The Universe on the History Channel and its sister channel H2, (now the longest-running science show on commercial TV in the US) has come to an end, and I’ve not actually known the answer (but have been assuming so). Well, the good news is that there are some new episodes being made! I know this since I was involved in some filming for a few segments on two episodes on Thursday. I spent the lunchtime session talking about novae and supernovae, and the […] Click to continue reading this post

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

Fail Lab Episode 9 – Aggression

fail_lab_ep_9_stillFail Lab Episode Nine, all about Aggression, is now online. See earlier posts (listed below) for thoughts about this excellent series on Discovery’s Test Tube.

(By the way, (spoiler alert) in the video they analyze this week, that looks like a bit like a Wing Chun move (and stance) to me… albeit a tad sloppy. And I note that it was used to end the aggression. A win for positive use of martial arts!)

Why Do I Study Physics?

why_do_I_study_physics_stillI was sent* this delightful short film recently. It is by Shixie (Xiangjun Shi) done as a graduation project at Rhode Island School of Design. It seems that it won prizes – quite understandably! – at a number of short film festivals, including one about science communication (which reminds me of the one I run). The film is entitled “Why Do I Study Physics?” and it is a lovely piece of writing and hand drawn simple animation that’s very […] Click to continue reading this post

Fail Lab Episode 7: Tribalism

fail_lab_ep_7_still

Fail Lab, the web series on Discovery’s TestTube channel that I’ve been telling you about, is growing in popularity. People are hearing about its unusual charms as an edgy, funny, quirky, smart vehicle for some food for thought and are going to see. That’s great. There was a review on VideoInk today that seems to “get” series creator Patrick Scott’s “Zoochosis” point of view that informs his particular style of filmmaking, and that was good to see (although I don’t agree that the hard science can get lost sometimes – this is the online world where the viewer can take charge – if you miss an idea, just scroll back and watch it again. That creates opportunity for density in making intelligent programs, and hopefully steers us away from shallow, lowest-common-denominator programming).

Anyway, episode seven is now up, and fueled by a remarkable video it delves into ideas about how we relate to each other, within and without social groups. Here’s the embed: […] Click to continue reading this post

Big History is Coming!

big_history_promo_still

You’ll recall that I was in New York a short while ago to film some promotional material for a new TV series. It is called Big History, and it will be on History Channel’s H2 channel (and eventually on various international channels, but I’ve no idea which – similar ones to where you find the other show I’ve mentioned a bit, The Universe, I expect).

Rather than be primarily about astronomical and cosmological things, the show will focus each week on one of a list specific items that have affected our history, and take the long view about that item. How long a view? The longest known possible! So take something like Salt, and examine its role in civilization and culture, bringing in historians, anthropologists, etc… and physical scientists to trace that object back to its roots in the early universe… (the big bang, the cores of stars, etc.) Update: For you Breaking Bad fans, note that it’ll be narrated by Bryan Cranston, by the way.

Here’s one of the promo videos:
