Free Brainy Lectures for Everyone!

Posted by Danny on Friday, July 15, 2011 at 11:46 am

Thanks to the goofy interests of our usual attendants (and not, though the allegation would be fair, due to the name of the event), subject matter at Evenings for Brains tends regularly towards neuroscience and psychology in general.  As a result, I was acquainted with V. S. Ramachandran’s TED Talk, and was subsequently chuffed all over to learn that he had produced an extended version of his presentation in the form of a five-part lecture series for the BBC.

Uncle Bert!

The Reith Lectures are named for John Reith, the inaugural controller-general of the BBC, and exemplify the corporation’s now (tragically) quaint and paternal-sounding charter to “inform, educate, and entertain.”  They resemble our Massey Lectures (or rather, the other way around), and might be positioned as TED Talks for folks with long attention spans.

When I first stumbled on the Reith lectures a few years ago, I asked around with various British radio buffs whether any attempt had been made by the filesharing and archival  communities to collect and release the series online, as I’ve seen done with the Goon Show.  I was told that it was a good idea, and that some of the more famous or recent lectures were in “circulation,” but that the body was vast and there was more missing than was accessible.  Particularly with old BBC archival material, this had a ring of doom about it: in the company’s (later, corporation’s) early history, it was notoriously in the habit of recording new programs over old reels.  I found my Ramachandran lectures, which were recent, and a single fragment of Bertrand Russell’s series, which was famous, and consigned the rest to a teary oblivion shared by the early seasons of the Goons, the pilot of Clue (until recently!), and some Doctor Who episodes which I wasn’t particularly broken up over.

It was enough of a jolt of good news to get me blogging again, therefore, when I learned from the ever-fecund Open Culture website that the BBC had made the entire series available for free as an international podcast!

Please, please try some of this stuff.  There are names in the list of lecturers you’re bound to know, or topics you already care about.  If you’re nuts like me, listen from beginning to end and witness the evolution of western social conventions and intellectual fashions—Uncle Bert often makes my heart sing, but his positivism is shocking and foreign, even to my idealistic, naïve self.  If nothing else, try the first Ramachandran lecture (or the TED, linked above), and see if you don’t want more.  I so wish the CBC was cool enough to do this with the Masseys; they sell the lectures on CD instead (at the time of writing, anyway—maybe they could maybe be shamed into opening up a bit by the Venerable Beeb).  As it stands, the Massey lectures are a bit more populous in the wild than the Reiths were, so folks with the right inclinations and skills will do what they will.

 

One other thing I’d like to tell you about, O Absent Readership, is another swell bit of totally legal, openly accessible brainy goodness served up by Stanford University and brought to my attention again by Open Culture.  Robert Sapolsky is a neurobiologist and primatologist, famous for his book, Why Zebras Don’t Get Ulcers, has been featured by TED, The Teaching Company, and Big Ideas, and has recently had his open course on Human Behavioural Biology broadcast to the world, OCW-style.

Sapolsky’s name was familiar from the Teaching Company catalogue, but I hadn’t seen him teach until I watched the clip featured on Open Culture.  Their pitch is my pitch: try a few minutes of the first lecture—if you’re hooked, the whole course is available to you.  (The ability, from home, for free, to see a professor teach and to say, “gosh, I wish I was in his class,” and then to be able to watch ALL the lectures in that class, is like paradise.  It’s transmission-based learning, but it’s still so, so tasty.)

What’s most valuable about this series, for me, is that Sapolsky provides a fairly thorough overview of the various lenses for viewing human behaviour scientifically, but is ever at pains (or, takes sadistic pleasure) to tear down the confident edifices of various modes of thought.  He uses the metaphor of being trapped within one of many “buckets” when trying to explain human behaviour: evolutionists, molecular geneticists, and ethologist care about different things and countenance different kinds of evidence when explaining phenomena they would all equally recognize.  Exploring the conflict between the different buckets, as Sapolsky does here, breaks down the apparent monolith of scientific accord and offers a more accurate picture of this particular way of understanding the world.  For this I have great affection.

My approach to the lectures has been to download them from YouTube using FlashGot (free!), rip the audio data from them with AOA Audio Extractor (free!), and then listen to them on my iPod while commuting (fun!).  For the buckets with which I’m familiar, this has worked pretty well, and I try to watch the lectures covering stranger topics, like neurology.  It’s been awfully rewarding and compelling for me; I hope some of you find this useful, too.

Alan Davies Measures String! Amazing!

Posted by Danny on Thursday, March 3, 2011 at 11:32 pm

A quick post and a long video: Alan Davies of Quite Interesting fame recently featured in an episode of the venerable BBC documentary series, Horizon.  In the grand pedantic tradition of trying to answer rhetorical questions, Alan wanders through laser measuring technology, fractals, atomic structure, and quantum mechanics as he tries to figure out “how long is a piece of string.”

Davies is impossible to dislike, as most QI watchers will probably attest; I think this video could be a good teaching tool because his bafflement, occasional glazing, and plaintive insistence on real-world relevance resonate with a lot of the students I’ve seen who are dealing with these ideas for the first time, and could thereby possibly spin sympathy into engagement.  Moreover, through the frustration of just trying to figure out how long his piece of string is, he remains stoic and good natured—this is pleasant.

A couple of final points: I’m usually impatient with some of the more popular conventions of documentary filmmaking, of which plenty are employed in the above video; I nonetheless found this a rewarding view in toto.  Secondly, the YouTube version linked to in the Open Culture post where I found this originally has already been taken down.  If you get to this version in time and find it a worthwhile resource, you might consider nabbing it while you can.

It’s a plane.

Especially for accomplished photographers who have the skill, patience, and nerve to capture mind-blowing images of nature, it’s a shame that Photoshop has ruined Truth.  Even if their motivation is internal and they’re not especially interested in riches and fame, it must be a little deflating to consider that a recent triumph needs to weather a gauntlet of cynicism (let alone scepticism) before it might even be enjoyed by other people.

The image above was posted on Astronomy Picture of the Day and linked back to a fairly active Australian astrophotography community where the image is still being celebrated, so I think it’s real, and consequently Awesome.  I need to become cool enough to maintain an active sky-watching lifestyle, I need to have a nice DSLR, and then I will delight in capturing the welkin.

Also, speaking of CCDs and capturing the sky:

Gems and Ink

Posted by Danny on Friday, November 26, 2010 at 3:27 pm

There’s an increasingly rare type of fountain pen ink that was discontinued in 2001 called Parker Penman.  The problem seems to have been that the ink was unusually saturated and included a suspension of metallic particles, achieving vibrant colours and fun reflective effects (as Diamine Majestic Blue is known to, today) but also clogging the pens used with a greater frequency than Parker wanted to be liable for.  Naturally, these inks have become sought after for their now unique properties and historic cache by aficionados who are prepared to maintain their pens more fastidiously, so the price and mythos of the ink have grown.  Penman sapphire is the most expensive ink I know of, selling often for more than $50 a bottle (current in-production inks tend to peak at $30 and most can be had for less than $12); Penman Ruby and Penman Emerald follow closely behind.  Gemstone names are fairly common in inks and there are huge differences between the “ruby” of one brand and another.  However, because of the enduring allure of the Penman inks, new inks that share their names are often decried for being the “wrong” colour—“that’s not sapphire, it’s too light, etc.”

What’s the best way to resolve disputes around emotionally-charged, contending aesthetics and nostalgia-induced disappointment?  Science.  The tremendous success of the Periodic Table of Videos (direct link here, or go here to read my ancient post) has encouraged further chemistry-based videos with the ever-beloved Dr. Martyn Poliakoff, including a recent one on the chemistry of gemstones.  If you’re interested, you’ll get to learn about diamonds, sapphires, and rubies; more importantly, you’ll see Martyn’s wedding photos.

Fun with Scale

Posted by Danny on Friday, February 5, 2010 at 12:13 am

Yay, more astronomy, sort of.  I think It’s safe to assume that most people who’d read this blorg have heard of (and probably by extension, seen) the Powers of Ten video produced by IBM in the bygone era of the ancient 1970s, but if not, here.  (also, a heritage-style website may be found here.)

I love the tour through the sciences, moving from cosmology at the outer extent of the journey, through astronomy, then sociology (what the hell, right?—urban sprawl and stuff), biology, chemistry, and then physics.  Also, the narrator has the sort of voice that’s only broadcast without irony in productions that are at least two decades old, or The Sciences.  Bob MacDonald of Quirks and Quarks or Jay Ingram of Daily Planet are local exemplars.

Recently(ish) on Astronomy Picture of the Day, they featured a video that struck me as a contemporary successor to Powers of Ten, and which I present below.  If you have the bandwidth, I strongly suggest viewing this at 720.  (Also, if you’d like to read the APOD commentary, it’s here.)
