It Fell From Space…

Comments Off on It Fell From Space…

the_universeTonight’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).

Head in the Clouds…

clouds_and_smoke_2Stepping 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 →

Mount Doom?

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):

Wish the Observatory Good Luck!

60 inch at mount wilson 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 →

Smoke

By | | ,

fire_sunriseThere’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 →

New Beginnings

campus_1Yes, the new semester and new academic year started yesterday, and today saw my first class of a new course for me to teach – Physics 508b: Advanced Electricity and Magnetism. The bad news is that it is a new course for me and so I have to write new material, plan new things entirely, and generally put in a lot of raw preparation from scratch for some things. The good news is that it seems that I have, overall, a good group of students to teach, based upon the willingness to interact that I saw, with good humour, good questions, interjections, and so forth. Further good news is that I’ve an excellent TA for the course (who also does research with me and so we can go back and forth from teaching matters and research matters) and that I’ve taught Physics 408b for a few years. The latter is an undergraduate advanced E&M course (based on Griffith, in case you’re wondering), and while this 508b course (based on Jackson) is heavier in detail and depth on the same material, I can borrow some of the more challenging material from the […] Click to continue reading this post →

Summer Reading: KC on Science Friday

frank_oppenheimer_book-coverScience 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 →

Toe Temptation

So the other day I was sitting chatting with someone I’d just met and at some point I looked down…and jumped a little in surprise at what I saw. Those shoes were a surprise since for a moment there I thought the person is rather unexpectedly barefoot – but the colour is even more unexpected. Then there was maybe a tiny X-Men moment (Oh! It’s Mystique…) but this all happened all in a flash before settling on the correct answer – it is a kind of shoe I have not seen before. I’d seen the cloven hoof type of shoe, which can have a sort of cheeky and slightly electric beguile to them when worn by a woman with the right devil-may-care attitude, but these were new to me. Worn with boldness, these can really work too, and maybe in the same way, but it is a dangerous tightrope to tread (the person I was meeting with pulled it off admirably!).

Upon returning home I looked them up a bit more (they are called Five Fingers shoes) and I oscillate between giggling at the whole idea and being intrigued. I gather that they are hugely comfortable and that grabs me. But yes, they are somewhat singular. They are so utterly unconventional that I find myself amused by the idea of all the “inappropriate” places I could wear them to. Witness some of the levels of amusement:

the_universeI 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 →

Harvest time. Seriously depleted crop due to the Great Tomato Atrocity, but the countermeasures have allowed me to claw back a little satisfaction. Now time to see about making some nice chutneys or other preserves. By the way, have you noticed all the stories in the press about the sudden rise of interest in gardening to grow food at home? See/hear an interesting NPR one here. (Many claim it has much to do with the Obamas’ White House garden, but you and I know it is all because of my blogging about it here over the years, right? …Right? ;))

Aaaaanyway… here are some other shots of the harvest/harvesting: […] Click to continue reading this post →

Scenes from Work

cvj_at_workThe 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 →

Gold

small_tomatoes_2Since I launched the campaign against Fluffy, I’ve actually been able to eat from my garden. Last week at my film premiere I was able to serve prosciutto-wrapped figs as one of the early courses, for example. (That was aided by also wrapping nets around the fig trees against the birds.)

Very satisfying, it must be said, is the crop of tomatoes of various types that have returned. After the Great Tomato Atrocity, this is very good to see.

Shine a Light

It is Friday, so time for a film release. So, get your popcorn, your ice-cold drink, and find your comfy chair! It has been a long time coming (see related posts listed below), but finally the first of the series of films I’ve been talking about is ready for you!

But before I run the projector, let me say a few words. As I said before, this short film is (I hope) fun, engaging, and informative. I hope lots of people take the time to watch it at least a couple of times. A basic scientific knowledge of the world is for everyone. Science is part of our culture and should be more widely circulated. Films such as this is one of the ways the National Science Foundation, who provided the support to make it, is helping to bring science to everyone. For this (and the other ones in the series) to be a success, your help is needed. It needs to be seen. Tell your family and friends, colleagues and students, local teachers, etc., about it. Forward it on to people you know. Blog it, tweet it, facebook share it, etc. Crucially, remember that it is designed to be not just for people who already know they have an interest in science, but others too, so make no assumptions about who might like it… just please send it. Thanks.

Ok, let’s dim the lights! Run the Projector! (Tip: It is a high video quality, so pause it and let it buffer […] Click to continue reading this post →

[Update: The film is here!]

Well, it is almost the big day! The first of the films I’ve been working on (see several earlier posts listed below), having had its world premiere on Sunday, is about to go on general release. It is the first of a series, and there is a second one to follow later in the Summer.

It’s a fun and educational short that I hope you’ll watch and tell all your friends about. Seriously, if you’re interested in science education (or just science as fun) do spread the word about this by blogging it, tweeting it, and sharing it on facebook and other sites.

This is very exciting! As with most film releases, however, there’s got to be a trailer. Straight out of the editing room to you, I present said trailer. Enjoy!
