National Academy

As part of a report on a study (or several studies) I was writing last week (because evidently I can’t find enough things to keep me from making progress on the Project), I was including some data on the geographic distribution of members of the National Academy of Sciences within the US. The focus was on Physics, Astronomy, and Applied Physical Sciences. It was rather interesting, binned by state, especially if you grab the columns and tell Numbers to throw up a graph of it all. The concentrations are striking. I wondered whether the concentrations were simply following population, at least roughly, and so I went elsewhere and grabbed the population numbers for each state and ran that into a chart as well. I’ll leave you to draw your own conclusions as to the results. I find them interesting. Look at California, Texas, and Florida, for example. […] Click to continue reading this post →

Pub Breakfast

p-2048-1536-3e449aa4-72a9-4dcd-bac1-d73bb46ae5c3.jpegI find myself in the odd situation of being in a pub in London well before 9:00am, having breakfast. No, things have not got so bad that I’m resorting to alcohol so early in the day, you’ll be relieved (I hope) to hear. (Things are good, on balance. Thanks for asking.) It is just that I took a rather strangely timed flight over from Los Angeles that meant that I was flying during peak waking hours in my body’s internal clock, and then arriving at 6:30am London time. This meant that I did not do my usual trick of getting at least some sleep on the flight…. So I find myself in London bright and early – way too early to check into my hotel. I’m groggy and hungry. Happily I found a pub […] Click to continue reading this post →

The Universe Returns – In 3D!

universe_glamour_shotSo I mentioned recently that we’d been filming for the fifth season of The History Channel’s The Universe, earlier this month and during some of the previous two. Well, I learned the other day to my surprise that the new season starts airing next week!

On Thursday 29th July at 9:00pm (8:00pm central, but check local listings) the first episode will air. It’s a survey of some of the wonderful things in our solar system. You can find a synopsis here.

Now do you remember that I did a post at some point about being filmed in 3D, and […] Click to continue reading this post →

five_finger_shoes_in_actionWell, I got some. I recall blogging about seeing these some time back, and am impressed with them now that I’ve been trying them out for a week. Let me say however a couple of things. I’m not going to spout all the stuff being said about how this is all so much more “natural” than shoes, and so on and so forth. There’s a lot of that being said and I find myself generally deeply suspicious of the way the word “natural” is used to sell products, especially to a certain type of crowd who falls for this stuff. What does “natural” even mean, anyway?

I like these because they are like being barefoot without the pain and discomfort that often comes with it (stubbing toes, icky or sharp things underfoot, etc). I do not think these “five-finger” shoes (as they are called) will replace shoes for me in most circumstances. Apparently people are running in them, hiking, even mountain climbing. Good for them. I want much more support on my feet when I’m doing those things and that is why shoes were invented. Marvellous invention, shoes. Not clear to me shoes are any less “natural” than these are. They’re just different. Like cycling is not “natural”, but is a rather splendid thing humans came up with that I see nothing wrong with on the “natural” vs “non-natural” front.

See also shirts, pants, skirts, etc. Same thing.

But, in short – these are great. I was told by the fellow in the shop that they are becoming hugely popular now, although I am not sure I believe that since I’ve only ever seen one person out there wearing them, and that was a while back. (It is in shoe-sellers’ interest to make these claims.) I got them because I’ve a bit of a heel […] Click to continue reading this post →

Bad Universe

Comments Off on Bad Universe

Phil Plait of Bad Astronomy has announced what his super secret project has been. It’s a new science TV show for the Discovery Channel! It is called “Phil Plait’s Bad Universe”, and I imagine it’ll be a lot of fun and quite informative. There’s a trailer and some of his thoughts about the show here. I could not work out when it is going to air, so keep your eyes peeled*.

Enjoy!

After spending more than half the day writing a report, fiddling with data gathering for the report, and dealing with various annoying issues in background over email, it is nice sometimes to be able to walk outside into the garden, pause to take a deep breath in the warm sunlight, and harvest some lovely tasty things.

Happy Higgs Hunting

lhcb_z_bosonIn case you were wondering, things are moving steadily along in the search for the Higgs boson, and in the general ramping up to study entirely new frontiers of particle physics. I noticed a couple of interesting articles today that give you a nice sample. The first, by Dick Ahlstrom in the Irish Times, and is about the announced “rediscovery” of the W and Z bosons at the Large Hadron Collider, by a team working at the LHCb experiment. (I personally think that the term “rediscovery” is somewhat misleading since it makes it seem like the community forgot where they (the key signatures of the unity of the electromagnetic and weak nuclear forces at high energy) were since their discovery in the early 80s, but let me not quibble too much.) The point is that experimental teams are refining their searching techniques while sifting through all the new data being produced in the collisions at the LHC, and one thing you need to do before you begin to look for new things (like the Higgs) is to make sure you can find and recognize old things. Especially very important old things. […] Click to continue reading this post →

Lemon and Chocolate for Breakfast

lemon_chocolate_cupcakes_1 Well, this morning I did an experiment. It began with zesting some lemons from the garden, and rapidly got into the business of mixing cupcake batter (recipe here – big on the lemon zest this time, and some of the juice), to make cupcakes… then melting chocolate (7 oz), pouring it over whipped butter (1 cup!), folding in some confectioner’s sugar (three cups or so), and a few drops of vanilla essence…. to make a chocolate frosting. More photos below, which you can click for larger views.

This (and my dutiful munching on tester cakes that ensued this morning) was all in aid of a nice test of a lemon cake plus chocolate question raised earlier. You will recall from an earlier post that author Aimee Bender‘s reading at Skylight of her new[…] Click to continue reading this post →

But is it Real? (Part Two)

Ah. Well, I was reserving the title of this post for a followup post to an earlier post about physics research. But, the film I went to last night at the wonderful Vista theatre was so engaging, and so excellently done – on the themes of dreams and memory – that I thought I’d use it.

escher_penrose_stairsChristopher Nolan has done it again! Inception (both written and directed by him) is yet another (remember my discussion of the Dark Knight two years back) example that shows that it is possible to make a big budget Summer Blockbuster that does not treat the audience as idiots. It tells you from the opening frames that you’re going to have to pay attention and think during the film, and that interesting ideas and themes are going to be explored, and it certainly lives up to that promise right through to the end. It is thrilling on all sort of levels, and for those who don’t care about ideas, there’s plenty of stuff blowing up and crashing into stuff to keep them happy.

I am going to say absolutely nothing more about it (more or less) since one of the […] Click to continue reading this post →

I’m Melting, I’m Melting!

Ah. Now I feel the Summer. We’ve been having a streak (starting Monday, or that’s when I noticed anyway) of quite hot days here in LA and, as usually happens above a certain temperature, sleepy_me_sketch_smallI’ve begun to be in danger of shutting down. I tend to get perpetually sleepy in such conditions, and wake up quite early in the morning (which is good for avoiding the heat with an early start), and so get to sleep relatively early. During the day I’m going at half speed if I don’t manage my temperature properly. I’m not a big fan of just switching on and blasting the air conditioning the whole day, so you can say it is entirely my choice to have these issues. Instead, I try to manage good airflow at times of day when it is possible, and shield interiors from heating up under the influence of the sun. It works pretty well, but there’s a point in the middle to late afternoon where things […] Click to continue reading this post →

Emerging Gravity

By | | , , , ,
23 Comments

In the New York Times this week there’s an article* by Dennis Overbye on Erik Verlinde and his paper on the idea that gravity is not a force at all, but a consequence of thermodynamics. You can think of it as an extreme take on one of the directions a lot of the research (that I’ve mentioned a number of times has been going on in string theory) has been pointing, although I think it is safe to say that there’s a lot to be done on making the statement a concrete one that you can do physics with. I think it contains the germs of the right thing we’re all reaching for, but does not quite get there yet. We’re now quite routinely formulating some of the key physics of gravity entirely as physics of a completely non-gravitational dual theory – this is the content of what we call holography – and in particular the quantum physics of black holes in those settings get holographically mapped to the thermodynamics of the non-gravitational physics. This is the basis of the tools that we’ve been applying to studying aspects of phenomena showing up in various experimental systems in nuclear physics and cold atomic physics (and studies of phenomena relevant to various condensed matter systems are also being done). I’ve told you about a lot of this in various posts. (Some of them are listed below.) Running this the other way, the model non-gravitational systems (certain gauge theories at strong coupling and with large rank gauge groups) can be thought of as examples of how gravity (and space-time itself) is really an emergent phenomenon, appearing simply as […] Click to continue reading this post →

Tales From The Industry XXXII: A Matter of Time

patzcuaro_clocksHere are some clocks I saw at the House of Eleven Courtyards (Casa de los Once Patios) in the historic town called Pátzcuaro (at the aforementioned lake of the same name). It was a convent, and is now a place to go and see lots of arts and crafts in action, as well as buy some. The clocks, housed in copper, mark the entrance to an entire room of copper workmanship in various forms.

The clocks have reminded me to give you an update on something else. Through some of May and June, I did a lot of work for the show The Universe, which airs on the History Channel (as you probably already know from reading here over the years. See here.). There will be, as usual, several topics covered over the upcoming season, and it will be interesting to see how the various filmmakers put together their episodes. It is worth noting that the History Channel have done something remarkable here. This is now the longest run that any cable channel has had for a science show. They built an audience with a solid show, and kept producing good episodes and gathering more (and it is worth saying, an admirably diverse set of) viewers over the years.

In fact, the show has been so successful that they are going to, I predict, pay an […] Click to continue reading this post →
