All Space Considered

You may recall that last month I hosted the First Fridays portion of the Natural History Museum’s day of celebration, where I introduced and steered the questions for JPL’s Adam Steltzner (lead engineer of the the “7 Minutes of Terror” Mars Curiosity landing). A fun event indeed. Well, this month I’ll be at another First Friday event, but for the other wonderful classic science space in the city, the Griffith Observatory.

They have a First Fridays series too – not to clash intentionally, I’ve recently learned upon inquiring – and it is a goal of mine to connect the relevant parties and find ways of having these events and spaces intersect with each other fruitfully, maybe. Perhaps participating in both of them is a good way to start. The “All Space Considered” event is a series where there’s a panel of scientists […] Click to continue reading this post

Meanwhile…

Yes, I found a bit of time to work on a page of the book. Here’s the development of a panel (click for larger view):

Indeed, the original rough sketch (done back during my Spring break retreat) shows that the panel was conceived a little differently. But then I decided to have a page with more fully rendered backgrounds, and so shifted the view in most of the panels […] Click to continue reading this post

A Perfect CicLAVia?

CicLAVia_June_20133Today’s CicLAVia was, in my opinion, almost perfect. It was always my dream for it (long before it actually got off the ground) to be an event that closed all of Wilshire from Downtown to the beach, to allow the city to celebrate car-free-ness on a regular basis. For me, having Wilshire be the route would make it a core location that meant the city was serious about the event, would mean a lot of participation linking East and West, and perhaps most importantly, would give a lot of room, since Wilshire is a really wide street. Perhaps that it is a long way off to have the whole of Wilshire be used, but they came close to the dream by having a Wilshire one today. The route ran from where Wilshire starts (at Grand) all the way out to LACMA at museum square at Wilshire and Fairfax. I rode it with a friend in the middle of the day and it was a lot of fun. See below for some of the things we did. Also, watch the timelapse video I made (embedded later) which has some fun stills embedded in it as well.

CicLAVia_June_20130You might recall some of the things that I felt the need to mention concerned me after the last CicLAVia. In that post I was most concerned about the narrowness of the route (they only used half of Venice for much of the way) and the fact that the resulting compressed group of people got even more compressed with the numerous traffic stops that there were. It was unpleasant and possibly dangerous. Well, there was not a hint of that here. They had both sides of Wilshire open, and relatively few traffic stops. This meant a lovely free flow of traffic for people of all speeds, ages, and mode of transport. The other main concern I had was that the event did not leave enough time for people to explore the route, leaving a number of people stranded, which is not good for a lot of people who are infrequent riders – they’ve got to get home cycling in traffic that they might not be ready to do yet. Well, today they extended the time by two hours, making it run from 9:00am to 4:00pm. Brilliant. I suspect that helped also with the potential congestion since people participating get spread out over a longer time.

Overall, I must congratulate the organizers for a nearly perfect event. Now if only we can have Wilshire open all the way to the beach for a CicLAVia, I’d be in heaven.

(Actually, just a few weeks ago I did my own all-Wilshire CicLAVia when I was heading to a couple of events at Westwood and Santa Monica. I started out planning to take my bike on the 720 bus but ended up giving up on the whole thing – there was a dreadful 45 minute hole in the schedule that made me horribly late for the first event and too many pushy people fighting to get on when the bus did show up – so I just cycled the whole way. It was a lot of fun, and helped me let off steam…but I’d love to participate in a whole group of LA residents doing it one day…)

So it was great. Having started Downtown and enjoyed the ride West, my companion and I […] Click to continue reading this post

CicLAVia Today!

ciclavia_june_23_2013So I am late in noting that there is another (much sooner) CicLaVia today! And it is the one I always thought should happen, right from the beginning – it runs right through the center of the city, down Wilshire Boulevard. (Well, my hope is that one day it can run all the way to the beach down Wilshire, but maybe that’s in the future). I note that the times have been improved, by the way. It is from 9:00am to 4:00pm, which is great. So it seems that this is one of the major things they did to improve the event. (See my post from April about various issues that came up.) Fantastic!

News from the Front, X: Smoother Transition

second_order_transition_1Yesterday I submitted a new paper to the arxiv. This is is my favourite curve from it. Some of you who follow the blog will recognize the blue circle-dots and guess that this is the output of the dot-generation I’ve been tinkering away at (and reporting on somewhat cryptically) since April (see e.g. here, here, and here). Correct. There are many reasons why that is the case. One of them might well be because it looks like a very comfy chair, and by time I’d submitted the paper, I was rather tired. I’d pulled an all-nighter to finish the paper because I wanted to submit it by noon yesterday, and the night before I had to spend several hours at a social event.

So once it was an appropriate time to leave the place I was at, I said my goodbyes, jumped on my bike, pedalled home, all_nighter_things put on some coffee, some Ana Tijoux (through headphones, so as not to wake anyone. Why her? Kinetic energy was what I needed at that moment – her vocal style is full of that. Try “La Bala” or “1977”. It is in Spanish, but that’s just fine.), and from 10:30pm to about 12 hours later, ground out the paper. I had to do this since I took some time away from the research project for a week, and then on Tuesday evening noticed the title and abstract of a new paper on the arxiv that suggested some overlap with what I was doing. So I had no choice but to gather all the results I’d been gathering the last several weeks and write them up and get them out, putting off reading the other paper until afterwards, so as to remain independent. Hence the all-nighter to finish it all. It was a pretty easy paper to write since I’ve had the results for a while, knew what I wanted to say, and it was just a matter of pulling everything together and writing a lot of background to set the scene for the results. A fair amount of the time was spent fiddling with things like how to generate figures from Matlab that embed nicely into the text, and so forth. Technical tedium.

The physics? Another reason I like the above curve is because it examines physics from an old favourite phase transition I co-discovered almost 14 – gosh yes, cvj, fourteen! – years ago. To my knowledge it is perhaps the earliest example of a […] Click to continue reading this post

Colour and Culture

colour_scribblesI spotted* this lovely post from a year ago about colour, culture, and language that I thought I’d share. What does the map of colour and colour names look like as you move from culture to culture. And are there universal aspects to it, or is it pretty random?

I find this a fascinating topic, and so was delighted to see this post, which addresses a lot of the questions. (You’ll find links there to an episode of Radiolab that was on a similar topic. I recommend that too.) Coincidentally, two pages before the part of my notebook where I’m doing a computation right now is a […] Click to continue reading this post

100th Birthday Fun!

Adam Steltzner’s talk was excellent and it was a pleasure to be the MC and introduce him and run the Q&A. (It was a tall order for me to fill Michael Quick’s shoes, but I gave it a shot.) The audience was really great, and there were several great questions. The wide shot (click for larger view) at the top is a panorama shot of the outdoor concert stage, with Devo just starting their set (GZA of Wu-Tang Clan was on just before). I took it* while standing under the fin whale skeleton that is the centerpiece of the new Otis Booth entryway pavilion that was unveiled just minutes earlier. (See more about that space and other new exhibits here.) Here are a couple of shots (click for larger view) from Adam’s session, where he gave an inspiring talk about the engineering of the landing of the Curiosity Mars rover, with reflections on space exploration in general**:

Mount Lee from Mount Hollywood

mount_lee_from_mount_hollywood_smallWhile in Griffith park yesterday evening I looked West when near the top of a rise and saw one of the great sights you can get at this time of year. The stretch of the Santa Monica mountain range coming in from the West shrouded in the mists rolling in from the West. The mist hides a lot of detail and leaves you with just simple layers of shade, almost monochromatic. It was quite beautiful. (Sadly, a lot of people who like to reach for the usual negative cliches about the city assume the mist is smog, but it […] Click to continue reading this post

100th Birthday Bash!

If you’re in town on Sunday 9th June, I strongly recommend coming along to this! The Natural History Museum is having its 100th Birthday celebration with an all day series of events. There’ll be new spaces and exhibits opening, including the new gardens they’ve been building for some time, and so there’s plenty to explore that will be new, and partly outdoors on a (hopefully) lovely day. (See here for an LA Times article on some of the changes.) As the day draws into the evening, there’ll be a real party brewing, with bands, DJs, bars, and so forth (see below). Kicking off the evening part of the proceedings at 6:30pm will be a talk and Q+A with JPL’s Adam Steltzner (of the Mars Curiosity Mission), in a spot hosted by me.

Adam’s a great guy, with lots of interesting things to say and a great sense of […] Click to continue reading this post

Maybe one of the best emails yet?

I get a lot of unusual emails each day. Typically, offerings of alternative theories of the universe with requests/demands to review them (sorry – please send them to a journal), discoveries of remarkable forms of energy saving or propulsion systems (People, I have my own crazy sh*t to work on – don’t ask me to work on yours too), offers of marriage and/or marriage-related things (Ladies (and, yes, some Gents), no thanks, I’m just fine.), and so on and so forth. But yesterday’s email is up there among the recent highlights. It was sent out to an anonymous group, so I have no problem sharing it here (I have removed the name of the sender):

Lattice Experiments

... and out it came, just as I finished hand-whipping some cream for an accompaniment. Hurrah! Apologies in advance to people who clicked over here because from the title they were expecting a post on discrete approaches to quantum field theory such as lattice QCD. This is mostly about lattice cherry pie, which, you’ll perhaps admit, is at least as interesting. Best to use the ones that have a slight sour edge to the taste, in my opinion… not too overly sweet.

Yes, it is time for an Asymptotia visit to the kitchen. Sunday I had a little dinner gathering for five, which called for an afternoon of cooking. I took some pictures, but in the end the set is incomplete since I got distracted with the important business of helping serve everything nice and hot and on time. So the main focus will be the pie (shown at the top so you don’t have to wait – the photo makes it look at lot darker than it actually is. It is not burnt!), since that’s all I have a complete set for. The […] Click to continue reading this post

SCSS Report

scss_may_2013Friday’s Southern California Strings Seminar was a success! Thanks to all who came, who spoke, and the UCLA organizers. I enjoyed all four talks that were put on, and learned a lot from each. (Sera Cremonini is giving her nice talk about duals of hyperscaling violating theories in the photo.)

I was particularly pleased about the talk by Daniel Harlow about the Firewall issue, […] Click to continue reading this post
