Animating Hair Is a Lesson in STEAM

logo

I am a proponent of the concept of teaching in a STEAM (science, technology, engineering, art, math) framework that goes across disciplines. I have seen many attempts to use science and math in teaching art - some successful, some not.

A new project that does this in an engaging way is a collaboration between Pixar Animation Studios and Khan Academy that is sponsored by Disney. Called "Pixar in a Box," it gives a look behind-the-scenes at how artists at Pixar need to use STEM to make art.

To make balls bounce, leaves in trees move in the wind, fireworks explode or realistic rippling water takes more than drawing skills. It requires computer skills and considerations of math, science such as physics and digital humanities.



In this learning series of videos on simulations, the Pixar artists use hair as an example of an animation problem that needed to be solved. Using examples from their films, such as the character Merida in Brave with her bouncy and curly hair, you learn how millions of hairs can be simulated if you think of them as being a huge system of springs.

As the lessons progress, you can learn about animation roles and will discover what a technical director does in the animation process.

The lessons are appropriate for grades 5 and up - though I can see many adults and younger kids interested in animation from a technical or artistic side enjoying the free series.


A 16mm Education

16mm projectorMy elementary school days were the 1960s and back then seeing a film in class was a big deal. Those 16mm educational films often left a bigger impression on me than the books and lessons. A decade or so later and I was the teacher in the classroom and I became very good at threading those old 16mm projectors that often ate up the film.

Television as an educational tool was pretty rare. I recall my fellow students sitting on the floor of the gym in 1962 to watch one small television set as John Glenn became the first American to orbit the Earth.

A bit more than a decade later I was threading one of those 16mm projectors as a teacher to show my students films. Some teachers took advantage of using films a bit too often. We called them "plans in a can" and they were popular emergency plans in case you were absent without warning or on a day before vacation.

I was pretty frugal in my use of films, but I also taught a course on film and video production, so I think I had legitimate reasons to show films. Before there were home video players, 16mm films were the only way to do it.

The Sony Betamax hit the U.S. in 1975, and my school bought a VHS videocassette recorder (VCR) in 1977 when it was edging out the Betamax for the home video market. That VCR was something I used more and more, though my students were still shooting their own video on reel-to-reel VTRs (videotape recorders).

Sony changed that with their 1983 Betamovie cassette camcorder. My school bought a full size VHS camcorder and so did I. My first home movies of my newborn son were recorded with a video camera plugged into a VHS deck.

But I have very fond and surprisingly vivid memories of those old 16mm films that I saw a s a kid in school.

Many of them have emerged online. I assume that many of these films have had their copyright lapse, or maybe the companies that produced them have gone out of business or just don't care about their use any more.

I recall this film on "Lunchroom Manners" as one I saw in school. I also recall Pee Wee Herman using part of it in one of his shows. Watching "Mr. Bungle" in school settings today reminds me of my own school and the kids look like a lot I did then and my fellow students. Since I have no film and video of my own early days, these are like home movies.







I can imagine teachers in the late 1940s and 1950s showing in a health class films like the 1951  "Going Steady." (It doesn't portray going steady as a good idea.) And I'm not sure how teenagers in 1949 would have viewed the tips in Dating Do's and Don'ts. These were made by Coronet Instructional Films, which produced hundreds of films for the school market.

Public domain films from the Library of Congress Prelinger Archive and Archive.org can be a real trip down memory lane for people who came of age in the 1940s through the 1970s.

But the films I saw in school that left the biggest impression on me were the ones about science. Many of them were well made and from Hollywood producers and studios. I vividly recall "Our Mr. Sun," a film directed by Frank Capra who is best known for It's a Wonderful Life, Mr. Smith Goes to Washington and many others.





That film launched the Bell System Science series. My father worked at Bell Labs in New Jersey then, so I thought then that he might have had some vague connection to these films (he didn't). It was the time time of the space race with Russia and an early version of STEM education that we all needed to know more about science. My father was determined I would be the first in the family to attend college and really wanted me to become an engineer.

With animation and live action, "Our Mr. Sun" was really well-made for the time. Capra had been producing documentaries for the Army during WWII such as the Why We Fight series and this documentary side business continued after the war. I know I saw that film multiple times in school, but this Technicolor beauty was originally telecast in 1956 and 1957 to 9 million homes and then some 600 16mm prints were distributed to schools and community organizations through the Bell Telephone System film libraries.

Another film I recall was on the atom. I grew up in that "atomic age" when the fear of nuclear war was very real. The film I recall was produced by Walt Disney Educational Media. Walt Disney began hosting his own television show for ABC in 1954. In exchange for a weekly hour-long Disney television program, ABC was funding some of the construction of Disneyland. The show was originally named Disneyland but went through later incarnations as Walt Disney Presents, Walt Disney's Wonderful World of Color, The Wonderful World of Disney etc. All in all they ran for an amazing 54 years.

The "Our Friend the Atom" was a pro-nuclear energy film but it did compare atomic energy to a genie in a bottle, both of which are capable of doing good and evil.







Not all the films were about hard science and another one I recall must have had some impact on my decision to go into the humanities and major in English. Another from the Bell Science series produced by Frank Capra was "Alphabet Conspiracy" which was the story of the science of language and linguistics. The premise was a plot to destroy the alphabet and all language and it featured the very odd Hans Conried.

The growth of television after WWII scared many parents and educators. Kids were watching a lot of TV and, like film and comic books before it, the fear was that it would rot their minds. The same cry was heard with videogames, the Internet and now with smartphones, which contain all those formats.

I wrote my Master's thesis on the influence of television on children in regard to violence and isolation. There is no doubt that all this media influenced several generations, but I'm not sure that it rotted any brains. I suspect it inspired many kids.

The Augmented Reality of Pokémon Go

Go
People have been searching for creatures and running down their phone batteries this month since Pokémon Go was released.
Is there any connection of this technology to education, Ken? Let's see.

First off, Pokémon Go is a smartphone game that uses your phone’s GPS and clock to detect where and when you are in the game and make Pokémon creatures appear around you on the screen. The objective is to go and catch them.

This combination of a game and the real world interacting is known as augmented reality (AR). AR is often confused with VR - virtual reality. VR creates a totally artificial environment, while augmented reality uses the existing environment and overlays new information on top of it.

The term augmented reality goes back to 1990 and a Boeing researcher, Thomas Caudell, who used it to describe the use of head-mounted displays by electricians assembling complicated wiring harnesses.

A commercial applications of AR technology that most people have seen is the yellow "first down" line that we see on televised football games which, of course, is not on the actual field.

Google Glass and the displays called "heads-up" in car windshields are another consumer AR application. there are many more uses of the technology in industries like healthcare, public safety, gas and oil, tourism and marketing.

Back to the game... My son played the card game and handheld video versions 20 years ago, so I had a bit of Pokémon education. I read that it is based on the hobby of bug catching which is apparently popular in Japan, where the games originated. Like bug catching or birding, the goal is to capture actual bugs or virtual birds and Pokémon creatures and add them to your life list. The first generation of Pokémon games began with 151 creatures and has expanded to 700+, but so far only the original 151 are available in the Pokémon Go app.

I have seen a number of news reports about people doing silly, distracted things while playing the game, along with more sinister tales of people being lured by someone via a creature or riding a bike or driving while playing. (The app has a feature to try to stop you using from it while moving quickly, as in a car.)

Thinking about educational applications for the game itself doesn't yield anything for me. Although it does require you to explore your real-world environment, the objective is frivolous. So, what we should consider is the use of VR in education beyond the game, while appreciating that the gaming aspect of the app is what drives its appeal and should be used as a motivator for more educational uses.
AR
The easiest use of VR in college classrooms is to make use of the apps already out there in industries. Students in an engineering major should certainly be comfortable with understanding and using VR from their field. In the illustration above, software (metaio Engineer) allows someone to see an overlay visualization of future facilities within the current environment. Another application can be having work and maintenance instructions directly appear on a component when it is viewed.
Augmented reality can be a virtual world, even a MMO game. The past year we have heard more about virtual reality and VR headsets and goggles (like Oculus Rift) which are more immersive, but also more awkward to use.This immersiveness is an older concept and some readers may recall the use of the term "telepresence.” 

Telepresence referred to a set of technologies which allowed a person to feel as if they were present, or to to give the appearance of being present, or to have some impact at place other than their true location. Telerobotics does this, but more commonly it was the move from videotelephony to videoconferencing. Those applications have been around since the end of the last century and we have come a god way forward from traditional videoconferencing to doing it with hand-held mobile devices, enabling collaboration independent of location.

In education, we experimented with these applications and with the software for MMOs, mirror worlds, augmented reality, lifelogging, and products like Second Life. Pokémon Go is Second Life but now there is no avatar to represent us. We are in the game and the game is the world around us, augmented as needed. The world of the game is the world.

Listening to Wikipedia


visualscreenshot of the hatnote visualization of Wikipedia edits



There is a wonderful STEAMy mashup application online that lets you listen to the edits being made right now on Wikipedia. How? It assigns sounds to the edits being made. If someone makes an addition, it plays a bell. It someone makes a subtraction from an entry, you'll hear a string plucked. The pitch changes according to the size of the edit - the larger the edit, the deeper the note.

The result is a pleasantly tranquil random but musical composition that reminds me of some music from Japan and China.

You can also watch recent changes. A the top of the page, green circles show edits being made by unregistered contributors, and purple circles mark edits performed by automated bots. White circles are brought to you by Registered Users.

If you hear  a swelling string sound, it means that a new user has join the site.(You can welcome him or her by clicking the blue banner and adding a note on their talk page.)

You can select a language version of Wikimedia to listen to. When I selected English Wikipedia edits at midday ET, there were about 100 edits per minute resulting in a a slow but steady stream of sound. You can select multiple languages (refresh the page first) if you want to create a cacophony of sounds. You can listen to the very quiet sleeping side of the planet or the busier awake and active side. The developers say that there is something reassuring about knowing that every user makes a noise, every edit has a voice in the roar.

The site is at listen.hatnote.com and the notes there tell us that Hatnote grew out of a 2012 WMF Group hackathon. It is built using D3 and HowlerJS and is is based on BitListen by Maximillian Laumeister. The source code is available on GitHub. It was built by Hatnote, Stephen LaPorte and Mahmoud Hashemi.

Audiation is a term used to refer to comprehension and internal realization of music, or the sensation of an individual hearing or feeling sound when it is not physically present. Musicians previously used terms such as aural perception or aural imagery to describe this concept, though aural imagery would imply a notational component while audiation does not necessarily do so. Edwin Gordon suggests that "audiation is to music what thought is to language," and his research based on similarities between how individuals learn language and how they learn to make and understand music.

As the Hatnote site points out, Wikipedia is a top 10 website worldwide with hundreds of millions of users. It includes more than a dozen actual projects including Wiktionary, Commons, and Wikibooks. It uses more than 280 languages. Perhaps more amazingly, it has only about 200 employees and relies mostly on community support for content, edits - and donations. Compare that business model to other top 100 websites worldwide.
