Singh Case Over!

Excellent news. The libel case against Simon Singh has been dropped. BBC story here. (See my previous post for details.)

Most important quote is from Simon:

Dr Singh said he was hugely relieved, but expressed his annoyance that libel actions continued to be used to block what he viewed as legitimate scientific inquiry and debate.

“Other scientists, science writers, bloggers, investigative journalists, human rights activists – all get threatened with these libel suits,” he told BBC News. “And at the end of the day, the people who lose out are the general public because we don’t get to find out the real truth because these libel suits just stop good journalism.”

Very true, and there is much work to do on that aspect of the legal system, but for now, beers all around, ok?!

Babies!

hobys_rosette_05 This is a wonderful infrared image (please click on it for lovely larger view) of a region of star formation called the Rosette Nebula.

It comes from the Herschel space observatory, which was launched (along with the Planck observer) by the European Space Agency (ESA) almost a year ago, you may recall.

From the ESA website, here’s a bit more about what this is: […] Click to continue reading this post

Mount Wilson Open For Business!

Good News Everyone!

flames near mount wilson seen from atwaterYou may recall the terrible fires of last year in the San Gabriel mountains, and the scare about whether the Mount Wilson facility might have been overrun by flames. There were Tolkienesque scenes of flaming mountains, dramatic battles on mountaintops, and so forth. No Balrogs were involved (a far as I know), but it was nail-biting enough for many.

One of the fallouts (fallsout?) of this was that the public access to the Observatory needed to be suspended. This included the ability to reserve access to the famous 60 inch telescope for your own use for an evening, an activity that I have highly recommended (from first hand experience) here on the blog.

Well, I can happily announce (I heard this from my friend Shelley Bonus who works […] Click to continue reading this post

Other Accelerator Physics is Available

The alternative title for this post was going to be “Closing in on Unobtanium”, but I realized that it might be better to explicitly remind you that the Large Hadron Collider, understandably featuring in the news a lot these days, is not the only particle accelerator in operation. Such machines are routinely at work all over the world (for example, supplying hospitals with radioactive materials used in medical diagnosis), and doing various kinds of key research (recall as another example the RHIC physics I’ve told you a bit about in relation to certain applications of string theory). One such set of investigations involves finding new heavy elements, extending the periodic table of elements. Yes, just like happened with Pluto’s demotion and its resulting effect on your internalized list of planets in the solar […] Click to continue reading this post

She Blinded Me With Science…

The funny video below* is good for a bit of nostalgia for the time of the Thomas Dolby song, the song itself, and perhaps for the X-Files TV show (but not for me, I saw only a few episodes). Scully fans will love this, and although I never regularly watched the show, I did appreciate her character. Strong skepticism, insistence on using the scientific method, etc. Excellent. Good character overall, and broke a lot of ground as a female lead with these characteristics too.

chloe_obrian_24Now here’s an idea. Would someone please do such a video for 24’s Chloe O’Brian? (Pictured left.) She’s definitely one of my favourite technical expert engineer/scientist types on a major show, and Mary Lynn Rajskub does an excellent job giving her life, depth and likeability even though she’s fighting against all the geek/nerd stereotype characteristics they’ve endowed her with. In essence, she does it by embracing them. Her attention to detail regularly saves the day (world, city, state, whatever), and the lives of her colleagues, and in the last episode they even had her supposedly determining that light in a video was daylight by […] Click to continue reading this post

Occult Activity Tonight!

rws_zetaophocc1Oh yes. Occult. Exciting right? Those of us in LA and some other areas (apparently points in Nevada, Idaho, and Western Montana, and the cities of Calgary and Edmonton) will see have the chance to see something quite remarkable if we stay up until 03:34 Pacific time. I learned this from Phil’s blog. You can find out more from Sky and Telescope (that’s their figure on the right). The event is this. If you stare at the star ζ (Zeta) Ophiuchi, which is visible to the naked eye, it will go dim for about eight seconds. Why, because an asteroid (824 Anastasia) will pass directly in front of it. You can’t see the asteroid directly, since it is too small and too dim, but nevertheless its presence between you and the distant star will be enough to make it go dim for a bit. Isn’t that wonderful? Have a go!

This remarkable effect (called occultation – hence the sneaky blog post title: the key root meaning here is “hidden”), while it might seem rather mundane in some ways (although you’re seeing the effect of an asteroid with your own eyes!) is extremely powerful in astronomy. It is a great way, for example, of detecting planets orbiting other stars! You’re familiar with occultations already actually. When the moon moves […] Click to continue reading this post

Awesome

obama_light_sabre I’ve never been one for the naive Obama-gushing, you may have noticed, but I can’t resist this lovely tribute. It is the site called “President Obama Looking at Awesome Things”, a collection of “photos”, and the example to the left is one of my favourites. (Click for larger view.)

It is excellent use of certain looks he gets on his face when doing things like “looking interested” at things. Isn’t photoshop great?

The site is here, and be sure to look at (currently) all three pages worth, or jump to the Flickr photo set here, where I learned that […] Click to continue reading this post

Inspiration and Dedication

jaime_escalante_by_robert_gauthierYou might not have heard of him, so I thought I’d mark the passing, on Tuesday, of the mathematics teacher Jaime Escalante. (Photo on right by Robert Gauthier.) He was an extraordinary teacher who passionately believed in the abilities of the many East Los Angeles students from disadvantaged and traditionally ignored backgrounds he taught, enduring the ridicule of his colleagues to press on with the job of teaching them as well as he could, challenging them to reach impressive heights of mathematical ability, especially considering given the circumstances. Some people might know some […] Click to continue reading this post

Great News for Healthy Skepticism

I don’t know if you’ve been following the story at all, but there’s been a major breakthrough in the UK for the ability of people to speak out against, for example, claims being made about the efficacy of medical treatments. It is very important, since the UK courts with their strong libel laws, are commonly used by big companies (with deep pockets) as a stick to beat anyone (such as a reasonably skeptical ordinary citizen who is not willing to believe extraordinary claims with little or no evidence for them) who raises questions. Simon Singh, a well-known science writer (whose work I’ve discussed here before) has, after a long battle, won a crucial appeal that may be […] Click to continue reading this post

Wonder

Over at Wongablog, Andrew points to a post he did over at Humanist Life in which he reviews “Age of Wonder: How the Romantic Generation Discovered the Beauty and Terror of Science”, by Richard Holmes. This is one of my favourite topics, and it is certainly a book I’m planning to read, although I have not done so yet.

Andrew writes thoughtfully on the book and the matter in general, and so I’ll leave you to wander over there and have a read of it. To tempt you, an extended (I hope Andrew does not mind) extract: […] Click to continue reading this post

New LHC Physics Phase Begins!

cern-first-physicsWell, here we go. It has been a little over 20 years since I’ve been actively working in this field and have been hearing about the promise of this machine, the Large Hadron Collider (LHC), and now it is really here, working, and colliding protons at an energy much higher than any previous experiment, promising us to a glimpse of new aspects of how the universe works. It is not guaranteed, of course, but there’s a great deal of hope, and so much of what we know strongly suggests that there’s going to be some exciting things to learn. See the list of related posts below for several bits of background on the LHC, or go to CERN’s website. [Image above right -click for larger view- is a CERN-supplied montage of data/images from the various experiments at the LHC. Caption: 7 TeV collision events seen today by the LHC’s four major experiments (clockwise from top-left: ALICE, ATLAS, CMS, LHCb).]

Two of the things foremost in people’s minds are on one hand the Higgs (the particle or particles that ultimately give masses to the elementary particles that make up the […] Click to continue reading this post

Picking Mushrooms

From Frances Bonahan s colloquiumAha. It’s one of those moments in mathematics press coverage that the journalists love, since all the stereotypes about how weird people working on abstract things can be are able to be brought out and highlighted, and words like genius, prodigy, recluse, eccentric, etc, get thrown about in equal measure.

Yes, Grigory Perelman has being turning down stuff again. You may recall him refusing the Fields Medal four years ago. Now he is refusing the Clay Mathematics Institute’s million dollar payout. Perelman proved the Poincaré conjecture a while back (see this older BBC article about that, along with a non-technical mention of the content of the conjecture – see also here, a related post the picture above right is from), which is on the Clay’s list of Big Problems whose collective heads have a bounty on them. He’s apparently a bit eccentric and the press love it, so most articles I’ve seen are mostly taken up with stuff like the following I saw in the Guardian:

A Spring Flower

wise2010-008-med It is Springtime, and it is not unheard of for me to have pictures of flowers, often from my garden, up on the blog (see here). This time, I have a picture of a flower from a different garden. It is the one you can see by looking up. If you look up with the right equipment, you can even see new growth (just like you can in Springtime gardens). In this case, the equipment is WISE (the spacecraft launched in December, recall) with its ability to survey the sky in the infrared part of the spectrum, and the new growth is a cluster of new stars, called the Berkeley 59 cluster. Looks a bit like a rosebud, […] Click to continue reading this post

A Return

gladioliI find myself back in Los Angeles for a bit, putting Walkabout mode on pause. Perhaps to do my laundry, perhaps to chair the committee of the upcoming Ph.D. defense of my student, Tameem, perhaps to be able to sit outside in the early morning sun in a T-shirt and blog over breakfast.

The garden is full of weeds and flowers, and all is well with the world, albeit a bit blurry due to my jetlag.

Anyway, a few random things to note:

* * *

mourning_dovesAnother Spring is here, in full force. I once again snort in exasperated laughter at the bizarre claim so very many people make about Los Angeles (Southern California more generally) not having seasons, as I marvel at all the many signs of it screaming for attention. As a random example, I’m observing some mourning doves eyeing me up from nearby as they try to decide whether I’m a threat to their potential nesting sites that they are checking out. Seems that at least one pair is rather impressed with my cluster of strelitzia nicolai and want to move in. I want to tell them that I’m not the problem, but the fact that they’d be in plain sight of the crows/rooks/ravens/winged-Nazgul that pass by here a lot will be. I’ve seen them strike nests in those trees from previous years and scoop up a tasty warm meal.

Not Entirely Alone, II

It has been a pleasure to see the large number of bikes in use in London, and particularly pleasing that it is a wide range of types of people using them as well. bikes_londonThere are many things about London that make it feel even more comfortable to me than ever (high prices of everything not being one of them) and the heavy bike use has to be one of them. Things in that department continue to improve over in my home city of Los Angeles, although I think it’ll still be a bit of time before you get bunches of cyclists routinely clustered at the lights waiting for the green, as in the photo on the right.

brompton_londonAlso great to see, sending a shiver of pleasure down my spine each time I’ll admit, has been the huge number of Bromptons in use in London. (See photo left.) I know it is true statistically that they are among the most popular single type of bike here (of any type, folding or non-folding) but it is still great that there are so very many sightings of them as you walk along the street especially at peak times. That’s something that really still has not taken off in LA. I’ve seen fewer than a handful of Bromptons in almost seven years on the streets here, relatively few folding bikes in total, and maybe only twice have I seen someone else using them in combination with the subway (and I remain the only person I’ve ever seen bringing them on to the bus). It […] Click to continue reading this post
