the myth of the war of the worlds panic

It wasn't a big thing.  Then why do so many think it was?

...

That’s the story you already know—it’s the narrative widely reprinted in academic textbooks and popular histories. With actors dramatizing the reaction of frightened audience members (based on contemporaneous letters), the new documentary, part of PBS’s American Experience series, reinforces the notion that naïve Americans were terrorized by their radios back in 1938. So did this weekend’s episode of NPR’s Radiolab, which opened with the assertion that on Oct. 30, 1938, “The United States experienced a kind of mass hysteria that we’ve never seen before.”

There’s only one problem: The supposed panic was so tiny as to be practically immeasurable on the night of the broadcast. Despite repeated assertions to the contrary in the PBS and NPR programs, almost nobody was fooled by Welles’ broadcast.

Separately, here are some interesting accounts of the production.

listen to internet radio stations

Many radio stations also put out a signal on the Internet.  Radio Garden is a nice map interface to find them geographically in a browser.  The iOS version (free) works well on my iPad.

After 40 years NPR's Morning Edition has changed its theme tune.   I was wondering if I had missed something...

Several people have enthusiastically recommended Gimlet's new Mystery Show podcast.  I'm not a big fan of mysteries, but for those who are here's a link.

 

 

the podcast boom

Podcasts are finallly becoming popular as a few great storytelling shows see success.  The amount of investment money is small - much of it is through Kickstarter these days - but it is real growth.  The New York Times on efforts by PRX.  Public radio is changing.

 

 

alix spiegel on radio and podcasting technique

I listen to a number of podcasts to get me through the otherwise mind-numbing boredom of exercising.  The medium is going through a huge growth phase and people learn to make a living and regular audiences materialize.  If you have an interest in various techniques this piece by Alix Spiegel is wonderful.  But she goes beyond technique ...

...

Which brings me to the real point of this manifesto. My firm belief that all of us – all of us dorky dork radio producers and reporters – should spend time playing with all the potential techniques available to us as story tellers – not just This American Life and Radiolab and NPR techniques, but Snap Judgment and Love + Radio techniques and Fresh Air and The Moth techniques. There are all kinds of people out there who have come up with all kinds of solutions to the problems of audio story telling. See if you can’t figure out what they are doing… and then create new solutions. Recruit other dorky radio friends and get together and analyze stuff and share ideas, and then watch YouTube videos and movies and anything else you can think of, and see if there is some small production technique in them that you can steal for yourself and your public radio brethren.

Which brings me to one more thing that I feel compelled to say. Innovation in radio is not just about production techniques. There are lots of ways to innovate. You can leave your production techniques untouched and take a new intellectual approach (we are taking a new intellectual approach with Invisibilia I think). You can bring in new kinds of voices to the system – which is profoundly valuable (though it’s not the only thing they do well, Snap Judgment does this incredibly effectively I think – they have amazing producers who bring voices to the system I don’t usually hear).

I love canadian radio...

CBC's often wonderful nightly "As it Happens" ran some classics on the Christmas Eve show... (mp3)

the first segment is a Christmas Eve tradition since 1979  - a reading of "The Shepherd"  

and, at about 57minutes into the show a bit about a most unusual seasonal hairdo for a long suffering wife...

 

reflecting on a meteor trail

Two regular readers wrote asking for more details on using radio scatter to "listen" to meteor tracks - something I do when it is too cloudy or light polluted to watch a meteor shower.

Radio waves travel in straight lines - the reason why we sometimes have communications that are not line of sight is mostly due to reflection.  This is really important for long range radio communication.  It turns out there are ionization layers from about fifty to a few hundred miles above the Earth.  There is a very small amount of atmosphere at those altitudes and UV and higher energy radiation from the Sun is enough to knock off an electron or two from these molecules.  The negative electrons want to reattach to a positively changed atom, but the distance between the two is now so great that it can take quite awhile.  The net result, when there is a lot of energy being dumped into the layer - is that a plasma forms.  This makes a nifty mirror.  

A lot of physics is involved and depending on the nature of the gases available, their density and how they are energized, the reflection and absorption properties of these layers strongly depends on the wavelength of a radio signal that is pointed at them.  Longer wavelengths - AM and shortwave radio - tend to have strong and useful effects.  You probably have noticed that you can listen to an AM radio station well over the horizon - even thousands of miles away - when the Sun goes down.  Shortwave radio DX - the practice of "working" distant sites - uses this in what can be a very sophisticated way.

In the 20s when Bell Labs was doing very careful radio propagation measurements, it was noticed bursts of distant signals sometimes appeared during meteor showers.  It turns out that a meteor dumps a lot of energy into the atmosphere that slows it down.  The closing speed of the average Perseid meteor is about 37 miles per second and they last about a second - so almost all of their energy is dissipated in a very small cylinder of atmosphere about 40 miles long and 80 to 100 miles up.  

Electrons from this gas are stripped and it takes seconds for them to recombine.  For certain radio frequencies this makes a nifty reflector.  If the reflector is between me and a radio station (30 to 50 MHz is nearly ideal it turns out, but FM radio -- about 100 MHz - isn't bad either) that is over the horizon it is possible for me to me to receive it for a few seconds.

The government (military and scientific projects) and even a company or two use the statistical likelihood of small meteors being around to reflect communications to operate low data rate networks.  This is a really cheap way to get a signal over the horizon and not use a satellite or ground based network.  Generally you keep sending a short amount of information over and over - eventually it is heard and recorded at a base station which sends an acknowledgement - when you receive that you can start all over again.  (there are more energy efficient burst detection protocols, but the idea is similar)

I've been fascinated with very low data rate communications for a long time and this makes sense for some people.  One project that has been rolling along for about 40 years is SNOTEL, which gives daily (and better) snow and precipitation information for the Western US and Alaska.  It would have been far too expensive to rely on satellites or conventional ground based networks.  Really nifty!

 

open source returns

Chris Lydon is back (thanks to Roger for noting this as well as Chris' mailing list)...

Dear Friend of Open Source:

The summer is over, and so is our hiatus.

The Open Source conversation is reborn at the Watson Institute at Brown University.

Please check in on what we've been up to at http://www.radioopensource.org .

Thomas Watson of IBM fame, who'd been Jimmy Carter's ambassador to Moscow, founded the Institute in 1981 to address the most urgent global risks of that day: nuclear hazards of the Cold War. Today the mission of the Watson Institute encompasses poverty, hunger, war and culture. My fellowship here commits me to keep exploring and innovating in the interactive new media - at the intersection of pod- and broad- casting where the new discourse of a global age is taking shape.

Brown and Watson overflow with blessings for Open Source, starting with the brilliant Rafael Vinoly building that both nestles and goads us to think anew. Nikita Khrushchev's son Sergei is upstairs writing, as is the exiled Zimbabwean novelist Chenjeria Hove, and former presidents Ricardo Lagos Escobar of Chile and Fernando Henrique Cardoso of Brazil. Geoffrey Kirkman of the Watson Institute was right when he told me years ago: the same swath of visiting stars that pass through New York and Harvard come also to Brown, but here they stay longer and they talk more. Brown students keep knocking on my door - this new rainbow generation of "millennials," most of them with digital media skills and native confidence in the expanding universe of the Web.

Not least, my Watson fellowship and the combination of avid Brown students and first-class recording facilities have let us cut radically into the "nut" cost of producing Open Source. So, not for the first time in human history, adversity has forced us into a precious opportunity to get lean, cheap and experimental again.

"An American conversation with global attitude" could be the motto of the revived Open Source. As always, we need your partnership here to locate the topics, guests and angles that will keep it richly distinctive. All we want to be, as we keep growing up, is - as many of you suggested, and producer Mary McGrath distilled the message - "the best damn podcast" on your computer or your Nano. But how long should the conversation run? And how often? What new features do you want on the site? How do we keep it making it more interactive with "the people formerly known as the audience" and with the world beyond our shores?

What we learned in two years on the last round is that "open source" works as well for public conversation as well as it works for advancing software. We announced a "conspiracy of the curious," and people joined it - with an unending flow of show suggestions and witty, critical, often impassioned extensions of the on-air conversation.

We learned also that podcasting works. The proto-blogger Dave Winer and I claim together to have done the first podcast in human history just a little more than four years ago. Between us, at Harvard's Berkman Center, we were the Neil Armstrong of the podcast moon, and now everyone's going there. For good reason. Podcasting is the cheap, democratic, speedy, listener-friendly universal means of sharing and archiving original sound files of every kind. Can we keep it new, or newish?

To begin, we've fired up the podcast feed of our summer gab which went from the Oscar Wao novelist Junot Diaz to the late John Coltrane, from the cyber prophet William Gibson to the unheeded prophets of our quagmire in Iraq. And there is tasty talk ahead with another of the "global" novelists, Ha Jin, on his first fiction set in America - with "The War" documentarian Ken Burns, and with the canonical critic Harold Bloom at Yale, among many others.

Let us end by saying again: Thank you. We couldn't and wouldn't be embarking in these Open Source conversations without the community of you -- that is, without the yeasty, resilient, generous, hungry, faithful, world-wide community that built and sustained Open Source from the beginning.

As always, coming and going, Emerson speaks to a great deal of what we're feeling. This comes from the end of his marvelous essay "Circles."

"Nothing is secure but life, transition, the energizing spirit. No love can be bound by oath or covenant to secure it against a higher love. No truth so sublime but it may be trivial to-morrow in the light of new thoughts. People wish to be settled; only as far as they are unsettled is there any hope for them."

Thank you for passionate, engaged, listenership and commentary these last two years. Now let us all together keep this "community of the curious" alive and growing.

So send us your news, your dreams and expectations, please, for the next ride on Open Source and reload your podcast here: http://www.radioopensource.org . Are you aware that you can subscribe (free) to the Open Source Podcast at the iTunes store? Go to iTunes, then the store, enter "open source podcast" in the search box, and then click on the Open Source icon and "subscribe" to get every episode.

In the spirit of Emerson: Onward, ever onward!

Christopher Lydon and Mary McGrath

generally great discussion ... the website and, of course, you can subscribe to the podcast.

Roger notes a fascinating piece with Michael Desch on our unaccountable political system.
