Well, this is what the countermeasures against squirrels and so forth, (introduced after the Great Tomato Atrocity) allowed the other plants to yield (to go with the crop from the smaller varieties two weeks earlier):
One of the things I seem to do each year is replace my tyres (tires? always confused about the spelling there…) on the Brompton for another year of cycling around the city (often in combination with public transport).
The beginning of the academic year seems to be about when I do it, which feels right somehow. It reminds me of my youth, when the night before the school academic year started there’d be frantic sewing of new school uniforms, or adjustment of old ones, to be worn the next day. I remember that always being a last minute thing, […] Click to continue reading this post
I make it a rule to never do that. It’s bad form. Best to be avoided.
Seriously, though, over on the Intersection, Sheril wants your kiss and tell photos. What she’s really looking for is…. well, here are her words:
Have you ever taken a picture of bears nuzzling in the field or kissing fish? How about a provocative pair of human subjects? (With their permission!) Are you interested in having an image credited to you in a science book debuting next Fall? If you’re a photographer with intriguing pictures of kissing and cuddling [no higher than PG-13 content please], email me before September 14 at srkirshenbaum@yahoo.com.
So go and send her some of your material if you have what she’s looking for! If not, consider making some new material. It’s for science.
Tonight’s 9:00pm episode of the History Channel’s The Universe ought to be interesting. It is all about objects that fall to earth from space. It’s a good opportunity to learn things about the universe (both near and far) from the perspective of things we glimpse arriving here on earth. You’ll get to learn about the earth as well, and how it (and life on it) has been affected by these things. There’ll be asteroids and planetary science of course, and maybe other things. I know from hearing some chatter of the program makers that there’ll be lots of demos using impacts and collisions and so forth. I know some good people were involved in making it, such as the writer/director Laura Verklan, and my friend and fellow regular on the show, JPL’s Amy Mainzer (who has an excellent blog here).

Stepping back from the unpleasantness going on at ground level for a moment (see the four previous posts, 1, 2, 3, 4), it seems that there is something else going on that’s actually quite fascinating. I went over to the top of one of the USC campus parking structures to take a look and gather some data and I’ve been chatting to people at random about it*. (This might also be a sign that I’m procrastinating on some other task… 🙂 ) That white part of the cloud is not smoke, is it? It is actually a cloud of vapour. Like a cumulus cloud you’d normally see in various weather conditions. I’ve heard some chatter about these systems “making their own weather”, and I can see that you could get a lot of localized heat dragging air in from other areas and so creating winds and so forth, but is that also generating this cloud? If so, how? Where is it getting all this moisture from? Is it from the water that is being […] Click to continue reading this post
Continuing my series of posts on the approach of the fires to Mount Wilson and the threat to the Observatory (see previous for information and discussion – this morning I am happy to hear that the radio news is now mentioning the Observatory and not just the tv and radio antennae up there)… Last night at about midnight I decided to look out to see whether I could see anything going on, and was greeted with a sight from the pages of Tolkien describing Orodruin (Mount Doom):
You can see the flames in the canyons near Mount Wilson’s summit, and as I watched […] Click to continue reading this post
The fires are racing up the sides of Mount Wilson as I write (19:38). They expect the burn to get to the top sometime in the next few hours, and yes, I imagine it’ll affect the Mount Wilson Observatory in some way.
[Update (20:59): You can get regular updates from the director at this page*. Seems that fire crews will remain on site for when/if the fires sweep through the grounds. ]
All of the working scientific equipment, including the solar telescopes and of course the historic telescopes (the 60 inch is pictured to the right) with which astounding discoveries were made about our universe (such as the fact that it is expanding, and the fact that the universe is vastly more than just our Milky Way Galaxy) are presumably in some danger, as well as support buildings of various kinds. I’ve no idea how much since I do not know what fire-proofing measures are in place up there, although I am sure there are several – such as keeping brush away from the buildings themselves. Here’s a camera up there on one of the solar telescopes where you can see regularly updated pictures that it snaps. I grabbed this one just now (click for larger view):
So keep your fingers crossed for luck for the instruments, and of course for all […] Click to continue reading this post
There’s a remarkable amount of smoke in the skies here in Los Angeles. Strangely there is little or no wind to accompany this super-hot day, and so the smoke is largely staying over the region where the fires are – the San Gabriel mountains, North of La Canada, Altadena, etc.
There was a bit of movement of the smoke overnight, and early this morning (while the sun shone dull and red like a sunset instead of a sunrise) there was some ash fall over where I live (I was working outside on some writing while it was still cool), a good number of miles away from the fires, in the city of Los Angeles itself, but this seems to have gone away. So there are clear skies in all directions, and then ominous-looking mushroom clouds in one direction. It is odd. This stillness is the reason the firefighters are having a lot of difficulty fighting the fires, actually – the smoke is affecting visibility for the various ground and airborne crews. There’s a lot of concern about what the fires will do next, (including a threat to the Mt. Wilson Observatory) and so let’s all keep out fingers crossed for luck. [Update: 6:30pm – I’ve heard that they have no choice but the let the fires take Mount Wilson. I hope that the Observatory survives ok. If you’re not familiar with the significance of the Mount Wilson Observatory, read here and here.]
Here’s a recent (about 5:00pm today) shot of the mushroom clouds of smoke. You can […] Click to continue reading this post
Heat. Following is a little bit of a whine. You’ll be even less sympathetic once you read the postscript, but such is life. Once the temperature gets up to a certain point, I can’t think any more. Well, not at the level needed to earn my living, if you see what I mean. Long periods of concentration start out well, but usually just turn into a nap. Not good at all, really. For the second or third day running we’ve had super hot temperatures with little movement of air to ensure a decent amount of throughput. This is not always unworkable, since one can simply nap during the day, do tasks that don’t require much sitting and thinking, and then work in the very early morning hours, but this time around there are two additional effects that ruin that approach.
The first is that the heat has been carrying on into the night (as opposed to dropping away rapidly in the evening as is the usual pattern), and the second is that there are two huge fires nearby, making the air a bit… chewy. (Left is a shot I took of downtown Los Angeles from the South showing the huge clouds of smoke from the La Canada and Altadena fires in the San Gabriels’ foothills in the background. From some views it looks like there’s been a small nuke detonated. Anyone remember 24 a few seasons ago? For some maps of the fire’s progress see here, and a view from one of the Mount Wilson observatories is here*.)
Both of these make for less than great sleeping conditions, and the feeling of lack of […] Click to continue reading this post
On Friday I was involved in an interesting conversation in an unusual format. It was a chat with cosmologist Anthony Aguirre at UCSD, and it was all about research in aspects of cosmology and of string theory, touching on issues such as the nature of quantum […] Click to continue reading this post
Science writer KC Cole (also a professor at USC’s Annenberg School for Communication) has written a biography of Frank Oppenheimer. She’s been working on it for a very long time and it has just been released, so if you look around, maybe she’s doing a reading/signing about it somewhere near you. (Some events are listed here. Los Angeles readers, she’ll be at Skylight Books tomorrow afternoon.) It is called “Something Incredibly Wonderful Happens: Frank Oppenheimer and the World He Made Up”. She was talking about it last week with Ira Flatow on NPR’s Science Friday. You can get audio here. Or you can listen to it embedded here and read on: […] Click to continue reading this post
I don’t know if you’ve noticed, but Sheril Kirshenbaum and Chris Mooney have written a book, “Unscientific America” with an excellent discussion about science literacy. You know from reading here that this is a favourite issue of mine (look under categories such as science and society), and by far the primary reason I blog, and do the various other activities I mention such as appearing on TV and radio shows, consulting for film, theatre, TV, etc, contribute to popular level articles, making films, and other things. It is vitally important, if we are a truly democratic society, for all to participate in the conversations we have about science – whether it be about issues to do with medicine, lifestyle, environment, energy, or just for its own sake: it is part of our culture. Sadly, science (and scientists) is still on the margins of the national conversation – people are afraid of it, giggle about how bad they were at it at school and then decouple from the conversation, mostly only pay attention to bleak or incorrect pictures of it in the media and entertainment (or for political gain), and so on and so forth.
What Sheril and Chris are doing in the book is examining the extent to which this […] Click to continue reading this post
I learned* a short while ago that the fourth season of The Universe on the History Channel starts tonight! As you may have read from a number of posts of mine over the last couple of months (see e.g. here, here and here), there’s been a lot of filming for this new cluster of episodes. I actually thought it was all going to start airing in the Fall, so this is a surprise to me.
There are some fun topics coming up in this season. There’ll be plenty of interesting things to learn, with contributions from a variety of interesting scientists telling you […] Click to continue reading this post
The College of Letters, Arts, and Sciences here at USC has built a new website, and gone quite far in including extra media, and links and portals on YouTube, Facebook and so on. One of the things they did was have a filmmaker make lots of videos. Lots. Things about faculty, research, teaching, learning, etc. All very exciting. Have a look, here, if interested. Mira Zimet, who makes the films, gave me a call and asked me if I’d like to contribute, and I agreed. I chatted on and on for about 45 minutes to an hour and she cut two short films out of it. The shorter one is on the site and has me saying some general things about research, teaching, science, and USC. Mira made the second because she thought it might be a nice extra video for the College’s YouTube portal. It has me talking a bit more about what string theory is and does, […] Click to continue reading this post
I’m 24 hours too late to warn you of the peak, which was this morning, but I imagine it will still be very good over the next few nights. This is the Perseid meteor shower. Apparently it is very good this year. So wander out when it is dark enough and see what you can see. Look toward Perseus, of course. More information here, from the Meteor blog, and the ever-excellent Stardate site gives you some directions (or look here).
In a big city like Los Angeles? Don’t automatically believe the lazy excuse that […] Click to continue reading this post
