Tales From The Industry XXI – Another Go At An Einstein Film

By | | , , , , , , ,

Well, since they’ve actually done a press release about it, I suppose I don’t have to be so coy as I was in the last post. This is about the film company I was doing some consulting work for on an interesting project with and interesting screen-writer.

The company is called Hero Pictures, and they have an interesting mission statement, and a rather splendid website (which I recommend… love the little hero guy) which tells you more. One of their projects is a film about Einstein. Working title is “The Private Lives of Albert Einstein”. They’ve bought the rights to a couple of books on him, brought in a screenwriter (see my thoughts on him and working with him in the previous post), Ron Bass, well known for his work on projects like Rain Man and The Joy Luck Club, Snow Falling on Cedars, among many other films.

It was fun to work with him on this, however briefly. He’s super sharp and gets the […] Click to continue reading this post →

On “Do-Overs”

By | | , , , , ,

I love “do-overs”. Not because I want to change anything in particular about my life, but because they are so rare, and so interesting. On my way to Vancouver on Monday, I got to do one.

We (myself and the other passengers) boarded our flight at Denver. I usually get on the plane early, and so have the change to watch people go through their routines of boarding and all that entails. After that was all, the plane full of passengers waited for the plane to get ready, doors to close, and so forth. It did not happen. After a while, the pilot came on and explained that they were trying to fix the radio, and it would be another half an hour. So we waited. After another long while, the pilot came on and said that they did not expect that the radio would get fixed in a timely manner after all, and so they were going to try something else. We would “de-plane” (a word I hate by the way – what is wrong with the perfectly good word “disembark”?) and all make our way to another gate where eventually another plane would arrive, and we’d take that one. It would be exactly the same type of plane. We would keep our ticket stubs and just re-board an hour and a half later.

I wandered for a bit, found something not too repulsive to nibble on (seems to get harder and harder in some airports), was disappointed by the meagre bookstore once again, and otherwise killed some time. Then the boarding started again. A “do-over”. Everybody would be going back to the same seats, it would be exactly the […] Click to continue reading this post →

Sharing the Storm

Here’s something I found rather unexpected. It all begins a little more than a year ago in Los Angeles. I was chatting with a friend, Aimee Bender, about our respective modes of work, and about how Summer fits into that in general. As you may know, Aimee’s a fiction writer, (and you may have picked up somewhere that I’m a theoretical physicist), and there are a lot of parallels to be found between professions that both involve lots of sitting around, crafting with symbols, folding fragments of inspiration together into larger nuggets, and so forth. So we chat about that from time to time.

A lot of how that works can be tied to the environment in which you do it, and so we got to talking about the long dry Summer in Los Angeles, with a particularly hot spell we were going through at the time we were talking. It affects how you work, what part of the day is most productive for you, and so forth. We agreed that a rather nice thunderstorm would be a good thing to have come along, even though that was highly improbable. Just the sound of a thunderstorm is a wonderful thing, and then there’s the relief it brings from the conditions before, and the smells in the air during and after. We carried on with the hot LA work cycle, stormless.

I left a week or two later for Aspen.

Shortly thereafter, Aspen went into a typical daily cycle of sunny for most of the day with a rainy downpour in the afternoon. Very refreshing. One of those days, that downpour turned into a long super-violent thunderstorm that lasted well into the […] Click to continue reading this post →

A Hop Over To Canada

Comments Off on A Hop Over To Canada

Well, as I said in the previous post, I’m leaving my hideaway/retreat mode and popping over to Vancouver for a short spell to help out at a Summer School. It’s the PIMS (Pacific Institute for Mathematical Sciences) Summer School on Particles, Fields, and Strings. I’m giving four lectures on some of the techniques in string theory that it helps to know in order to do some of the fun things we do to get at interesting physics (such as the topic of the post before). My title is something like “Perturbative and non-perturbative string theory”, and I’ve no clue what the level of the students really is, so goodness knows how far I will get in four one hour lectures. But it does not hurt to try. I’ll be laying the groundwork for several of the lecturers who will be talking about the more advanced stuff closer to their research work, and so I hope to at least help the students gain confidence with ideas and language that will show up all over the place in the two weeks following my presentations.

So what will I cover? Well, I’m going to tailor things to the responses of the students as […] Click to continue reading this post →

Black Hole Battles

lenny susskind, kc coleSomehow, I only learned about this today, and it is already standby tickets only, but you never know. If you’re in LA and interested in a different kind of conversation, consider taking in the event (part of the Aloud series) at the downtown Los Angeles Central Library tomorrow night at 7:00pm. It’s between two friends and colleagues of mine, the science writer K C Cole and the scientist Lenny Susskind! The event is entitled, “The Black Hole War: My Battle with Stephen Hawking to Make the World Safe for Quantum Mechanics”, and presumably will be about Lenny’s reflections on some of the exciting squabbles over various important issues in black hole physics that took place (and still take place) in our field of physics. The above turns out to be (I just learned from a Google search) the title of a book he’s written, so you might be interested in it for your Summer (or other) reading.

Some of you may recall her really great conversation with Alan Alda that took place at USC earlier this year. I reported on it here. K C tends to run these sorts of […] Click to continue reading this post →

On Good Ideas

A commenter, slim potato, implicitly asked a really good question earlier. It was a comment on a post I did yesterday about my struggles with a computation I was working in a notebook working on. I gave an answer, but since I know that a lot of readers don’t read the comments, and because one of the missions of this blog is to give a window on what scientists such as myself do and (importantly) how we do it, I thought I’d elevate the comment and my response into a post. Feel free to add your own thoughts to it in the comments, either as a non-scientist, a scientist, a specialist from another field, or other.

I would have assumed that most of your time when working on a paper was involved on catching good ideas, not getting muddled with conventions and calculations.

Hi,

Thanks. That’s a common misunderstanding of what we do. What makes a field of physical science like physics work is computations – all of that business with calculations (including checking that your computations conventions are internally consistent) is vital to the field.

Frankly, “Good Ideas” are a dime a dozen. Anyone in my field ought to be able to think of at least six of them before breakfast. What makes a good idea go […] Click to continue reading this post →

Once More Unto The Breach…

Ugh. A night of computing (while making and eating dinner and recuperating from a strange day-long headache – dehydration? side effects from the big hike the day before?) and muttering to myself at various points left me in a state of confusion last night. I went to bed tired and confused after getting into a muddle and realizing that I’d been probably mixing conventions in parts of my computations over the last few days, leaving me with a flipping minus sign in a result. No, I really mean “flipping”, since sometimes a 1/16 was -1/16, and sometimes that represents a physical truth and other times it represents a computational mistake – and I got confused as to which was which. Ugh.

All of this was coupled with occasionally wandering outside into the late night air filled with hungry insects in order to seek the fragment of wireless signal (I accidentally discovered it nearby on the weekend) in order to download the odd reference to check an idea or a fact. I’d have a few minutes before the bugs would find me and start to chew (I suffer from being particularly tasty to insect life – always the first person to be multiply bitten at any outdoor evening gathering), at which point I’d have snagged the download of the paper and can then run back in to the safety of indoors, flapping my arms around my head like a madman. It is an amusing dance, since I can find the […] Click to continue reading this post →

Altered Saturday Plans

river in aspenWell, I was supposed to go for an early morning hike to start off the day, but it has not happened. It was just meant to be a short one, since I’m staying in a little cabin out of town not too far from the start of a lovely trail. Then I was to go to the farmer’s market (more on that later) and then after lunch go to pick up my ticket for the chamber music concert I’m to go to this afternoon. (I say “pick up” and not “buy” since I was the lucky winner (well, one of them) of a little ticket lottery at the Aspen Center for Physics for tickets to concerts in the neighbouring Aspen Music Festival. Hurrah!)

Well, the hike did not happen. Why? Well, at about 6:30pm yesterday while scribbling fragments of equations and furrowing my brow while sitting in a cafe in town (a change of venue after a day at the Center(re) sitting in the office, you see), I began to realize that a computation I was stuck on might actually be becoming unstuck! Various parts […] Click to continue reading this post →

Although No News is Good News…

…(as the saying goes) it’s nice to get the real thing from time to time.

I’m almost fully in retreat mode now, being back at Aspen and settled in to my office at the Center and so forth. It’s good to see some familiar faces and catch up a little on physics news, and gossip (still waiting for some good juicy stuff there). I’ve settled into my accommodation (which on the plus side has no wireless or other web connection, but on the minus has HBO, which I shall have to studiously avoid), and have done a quick cycle around town (brought the Brompton again of course) to check that everything is in order. So by mid-afternoon on day one, yesterday, I was settling into my project(s). All good.

The good news of the title? Well, usually when someone contacts me about my book, D-Branes […] Click to continue reading this post →

Have a Fantastic Fourth of July, to everyone who is celebrating it!

fantastic four promotional skywriting over LA on the July 2005

It’s been several days since my last confession. Sorry about the silence. I’m honestly not sure exactly what I’ve been doing, since it has been a mostly fragmented set of things, coupled with a generally down mood of introspection over matters personal. Hmm… So nothing new there.

Physics-wise I’m a bit stuck. Not on a particular project this time, but stuck on […] Click to continue reading this post →

Final Thoughts

Well, it was a full day. Since this morning I’ve been putting the last touches on a paper with my student, V. I’ve been working at my home office (something odd going on with my office computer) while he’s elsewhere but present via IM. We can chat, exchange equations, drafts, and so forth, so it is good medium. Then mid-morning, I had a moment of confusion for a while, and progress stopped while I sorted that out. Discussions with V and another student, T, via IM about this and some other matters ensued, and then I was back on track, inputting edits from a session yesterday of reading it with pen-at-the-ready in a bookstore, inputting edits from V, and then another printout and review to add more.

Every now and again, a check of email, a walk around and a pull of the odd weed in the garden, and then back to it. Somehow this went on until 3:00 – three hours […] Click to continue reading this post →
