It is midnight and I really should get to sleep in order to wake up and work some more on editing the final exam for my class so that it can go to the printer by noon. But I’ve got several pokes from people clamouring to find out what The Project actually is, and I promised yesterday I’d start to spill the beans. Thanks for the interest! I think I’d better get at least some of it out there or I’ll have an angry mob by morning! So here goes. I will drag out the draft I sketched yesterday and beat it into shape:

So, as you may have guessed, The Project, which I’ve been mentioning here since a post way back in February, is a writing project, but it is somewhat different from what you might expect. The bottom line is that I hope that at some point into future you will be able to purchase a copy of your own, and that you will find it instructive, exciting, and enjoyable. At least.

Yes, it is a book about science. However… Well, here’s the thing. Over many years, people (friends, colleagues, potential agents and publishers, blog readers, etc) have been asking me when I am going to write my book. You know, the popular-level book that every academic who is interested in the public understanding of their field (as you know I am from reading this blog) is expected will write at some point. To be honest, I have given it some thought over the years, and it has been something I figured I might do at some point. In fact, several different ideas have occurred to me over the years, and I may well implement some of them at some point.

But a major thought began to enter my mind well over ten years ago. In my field, there is a rather narrow range of models for the shape of such books, usually involving about 80% of it being a series of chapters covering all the standard introductory material (some relativity, some quantum mechanics, and so forth) for the lay reader, before culminating in a chapter or two of what the researcher really wants to tell them about: some aspect of their research. This is a fine model, and it is great that people continue to write such books, and I will no doubt use that model one day, but to be honest, I don’t think there is any urgency for me to add to the canon yet another one of those books. Moreover, if you line examples of that type of book up against each other, you see that the […] Click to continue reading this post →

I, For One, Welcome Our New Arsenic-Replacing-Phosphorus-In-DNA Overlords

By | | , , , , ,

mono_lakeYeah! This is just the sort of thing I’d hoped that we (human beings) would find soon, in order to strengthen the idea that in looking for forms of life elsewhere, we be not just open to the idea that the basic chemistry for that life may be very different from what we are used to on earth (easier said than done), but that it is maybe even probable that this is what we could find first. Now, given the news today (announced by Felisa Wolfe-Simon and her team in a NASA press conference today and reported on in a paper to appear in Science) we know that it is not just a theoretical construction, but already a reality right here on earth. The researchers have identified a life form with a striking difference. The bacterium (which lives in Mono Lake – see NASA image above right) has DNA (and some other important complex molecules) with a major difference from all other forms we know. phosphorus has been replaced by arsenic!

periodic_tableThis works, by the way, because arsenic is in the same chemical family as phosphorus, being directly below it in the periodic table. Note that this is exactly the sort of thing that has been speculated about a lot in the classic days of science/speculative fiction concerned with alien life, remember? :- Silicon based life forms instead of the Carbon based ones that we know and love on earth. Silicon is again in the same column as […] Click to continue reading this post →

Nobel Scrutiny

1 Comment

Many people have found the Physics Nobel Prize (see here and here) this year quite remarkable, and mostly for positive reasons. It was given to innovative, young researchers Andre Geim and Konstantin Novoselov for work on a material that is remarkable for scientific and engineering reasons alike, and both theoretical and experimental. All good. Others have been a bit concerned about how very soon the prize was given for this work, and in other cases there has been some annoyance about how work on graphene has been attributed (a lot of people seem to be under the impression they discovered graphene, for example, which is not the case).

Well, it seems that there are quite a few strong words being written about the issue at very high levels. I was sent* a Nature News article (by Eugenie Samuel Reich) a day or two ago on the matter […] Click to continue reading this post →

ALICE Publishes!

Comments Off on ALICE Publishes!

Jacques Distler pointed out that ALICE has just published their first paper, only a little over a week after the beginning of the heavy ion phase of the LHC at CERN! Moreover, they are way ahead in energy of the previous heavy ion collision experiment (RHIC) and have verified “elliptic flow” (the main sign that the quark-gluon plasma behaves like a strongly coupled fluid, the big experimental surprise of some years back, with properties of a type that can be nicely captured using string theory models). Have a look at Jacques’ post here, and go directly to the paper of ALICE here.

Hurrah!

Please see my post from last week (“Experimental Excitement” was the apt title) about why I’m excited about all this!

Experimental Excitement!

By | | , , ,
11 Comments

alice_frist_run_dataWell, this week is a big week, in some ways. The Large Hadron Collider has gone into a new phase! For a while, the experiment has turned aside from the task of searching for the origin of mass (the Higgs Particle, or whatever it is that mediates the generation of the masses of elementary particles – see earlier posts, and features like this, etc) and is turning to heavy ion collisions. Rather than studying processes in which only a few particles at a time are interacting at super-duper-uber-high energies, the experiment will instead collide together the nuclei of lead atoms, so that you get lots of particles colliding together and creating a messy “soup” of high energy stuff all together. The goal is to understand the constituent nuclear particles (quarks and gluons) working collectively at high temperature (and low to moderate density), instead of focusing on issues concerning individual fundamental particles. Today (starting late yesterday, actually) is an exciting day because it marks the first step on the journey to probe deeper into this physics. The ALICE experiment has started looking at these collisions. See top right for some screen-shots of the mess of particle tracks that are left after the soup flies apart. The trick is to analyze all these tracks from millions of such collisions to work out the properties of the soup.

As you perhaps know from reading this blog, while of course I’m interested in the behaviour of fundamental particles and the origin of mass, and so on and so forth, I’m very interested in this nuclear issue too. Some of the most interesting work that […] Click to continue reading this post →

Passing Star People

John Williams in RehearsalYou might not know the name Maurice Murphy, but I am certain that you are likely to know – and maybe even be very familiar with – his work. His is the principal trumpet playing the lead themes in very many films with music by John Williams. I have for a long time been very impressed with how so many of those themes trip so easily off the tongue (physical or mental) and seem to fit together so well (just hum the Star Wars theme, and then follow it by the Superman theme, then the Indiana Jones theme, and so on). A lot of this is due to the fact that Williams (like most good composers) is a master at recycling and modifying, creating a cluster of much loved (deservedly) themes that accompany some of our favourite movie-going memories, but I now think that the other reason is that you’re hearing them all played by the same voice! That voice is the playing of Maurice Murphy, the truly wonderful trumpeter who Williams would specifically request to play the lead on recordings of his film music. Murphy died recently, and you can dig a bit more about him and explore what I’ve been telling you further by going to the London Symphony Orchestra’s site devoted to him […] Click to continue reading this post →

What are We Doing?

This is a really excellent talk* about how we educate, why we do so, and what has changed about what’s needed in education and society and why we may not have changed our methods enough to keep up with those needs. It is by Sir Ken Robinson, and was given at the RSA (Royal Society for the encouragement of Arts, Manufactures and Commerce) earlier this year. I love the way it is produced – using an animation/whiteboard-writing overlay for the visual concepts – partly because I had an idea of doing a series of short films with a filmmaker friend some years back that would do a similar thing (I had chalkboards)… but in a much less beautifully accomplished way than this! More examples are here. But, enjoy the talk… it is a superbly framed discussion, including many of the frustrations I’ve found myself expressing (sometimes here) about the system of which I am part! Thoughts welcome.

Make some Graphene at Home Today

As I prepare for the second of the Nobel lunches to be held on campus here today, I’m recalling last week’s which was a huge success. I’ll try to share more about that with you later. One of the things that I showed at the end, once the Physicists had talked about the Physics prize, was a lovely video showing just how easy it is to make graphene (the substance that was the subject of that prize) using sticky tape. People seem to find it hard to believe that it can be so simple, and that Nobel prize work can come from something so simple, but that’s the joy of this whole science research enterprise. You never know where the useful surprises will turn up. (You can get the raw material – the graphite flakes – from your local art supply store, by the way, or just break open a pencil…) Enjoy the video: […] Click to continue reading this post →

Start the Week

“A loose cat in Colorado must wear what?”

(I thought about this for a while, and could only come up with bawdy humorous answers…)

“A tail light.”

(huh?)

[Post written yesterday.] Yes, I am on the bus to work (above was from the on board entertainment system that sometimes asks quiz questions) and it is the start to another week. Another very full one, it is shaping up to be too. I find these days that if I am not careful I tend to measure a week’s potential a mostly in terms of how much time I will have to work on the Project. Like my research, it is not something that is served best by being chipped away at, catching a few minutes here and the between things, but involves a fair amount of immersion. (Having said that, I am getting better at finding tasks that I can allocate to chipping-away time, and I have even found certain things for it that I can do on the bus… A lot of this will become clearer later, I promise.)

inauguration_2There was certainly a lot going on last week, as I mentioned, and I did not even tell you the half of it. Things like going to see Ira Glass talk about his radio show, essentially doing it in the style of the show, and of course about four hours on Friday spent in costume with hundreds of my faculty colleagues marching in a parade and listening to long (but mostly good) speeches from various Vice-chancellors, Chancellors, Trustees, the Mayor of Los Angeles, and of course, the man of the hour(s), our new President Max Nikias, who we were, er, installing. (When people use that term, and they do here a lot, I always think of plugging in a new electrical appliance, or a new piece of software… I suppose the latter is closer to what we are doing than the former.)

This week sees a lot coming up too, the main thing probably being the first of the Nobel Lunches, scheduled for Thursday. I’ve been very pleased with these events – I […] Click to continue reading this post →

Guide To Science Writing

One of the things I pointed to in my discussion of science writing issues yesterday (see previous post) was this brilliant Guardian article by Martin Robbins. Of course, the classes had already seen it, and it is several weeks old now, but if you have not seen it, you simply must. It is so hilarious and so sharply observed that it should be as widely seen as possible.

Many of the comments left are brilliant too, written in the same style.

Enjoy!

(Waiting for the kettle to boil…)

It has been a rather hectic week for me here in the city of Angels. It is difficult to pull it all together in my mind and recall all the contributing elements, but they have been varied and more or less interesting and useful activities, ranging from various committees, teaching issues, research issues, event planning, event attending, and of course, the Project.

(Kettle’s boiled. Water poured on tea. Assam/Ceylon blend…)

gerardo_hacer_dogami_1I want to work for a bit before going to bed, although I’ll knock off early (midnight) because I’ve got to get up very early in the morning to get prettied up a bit, walk to catch the bus to campus, and get there by 8:15am or so. This is so I can get to my office and put on a cap, hood and gown and play dress-up (remember last time?) with hundreds of colleagues and so forth. The event? The inauguration of our new University President.

I’ve just returned from a long afternoon and evening in which I appeared in two of the classes of my colleague KC Cole (the science writer) talking about the issue of science, and how I do various aspects of communicating it to the public through various means (writing, film, tv, radio; factual, in fiction/drama, through blogging, in speaking engagements), and the broad issue of writing and journalism in that area. Two groups of extremely engaged and bright students in a row, separated by a quick […] Click to continue reading this post →

CicLAvia Report

ciclavia2010_4Well, it is not often I get to say this, but Sunday’s CicLAvia event was, for me, completely perfect. It was simply about community, family, and enjoying the streets. It did not have an overtly political or activist vibe to it (as is often the case when you try to do some things a little differently from others in this town, like ride the bus or walk to the grocery store), and I saw a lot more people simply enjoying (and remarking on it out loud) the fact that they were out on the streets of the city than I saw people proclaiming rabid anti-car sentiments, as I’ve seen at bike-centric events before. I think the former feeling will go a lot further in making lasting change than the latter in the long run. There was some political content around, but it was largely confined to the steps of City Hall, where (when I passed) there were endearingly naive chants being led by a bloke with a microphone about “LA saying no to oil!’ and “no to coal!”. Don’t get me wrong – naive is not necessarily used as a derogatory term here. Noble dreams begin with a heavy dose of naivete, I believe. Hope, against the odds, for significant change, and so forth. (I could use the fully decorated version, naïveté, but it looks a bit pretentious to me today…)

So the event was mostly about people getting out there and enjoying the city streets, and sharing their enjoyment by doing it together. I was impressed with the turnout […] Click to continue reading this post →

Getting ready to disappear off to explore. the route. Should be fun, although it is a tad too hot a day for it to be perfect for cycling and wandering long in the sun. On the other hand, that will bring a lot of people out to enjoy their Sunday outdoors, I hope, walking, cycling, rollerblading, skateboarding, running, etc. […] Click to continue reading this post →
