Jen You
like communicating about science. And UNC-TV needs folks just like you.
Let’s partner? Project: QUEST Regional Partnership Project; QUEST is a
project of KQED (http://www.kqed.org/quest)
designed to increase awareness and understanding of science and
environmental topics. The QUEST project established a new model f...or...
productive collaboration among a media organization and a diverse
collection of local/regional institutions and organizations. That’s
where we come in. UNC-TV was recently chosen as a partner station for a
two-year piloting process which includes, among other things,
establishing relationships with local, community-based organizations,
science centers, and/or museums, and developing new educational
resources. That’s where you come in. We’d like to know if you’d like to
partner with us, initially with ideas and insights on QUEST-related
projects. To find out more, simply e-mail jenjones@unctv.org (subject

Harris Educational - Reinventing Science Audio Recording History: In the video clip below you see a "Dormiphone" brand audio recording device from the 1950's. It used a single-loop tape cartridge called a Cousino Cart that was an evolutionary predecessor to the 8-track tape and the "Cart" used at radio stations. See the comments for more information

The Dormiphone had a programmable clock that would play the tape loop at given times. It was used as a memory building aid and probably also saw use in stores to make announcements at predetermined times.

The cartridge loop tape was also used in arcades to provide audio for games such as the puppet clown and the fortune teller in the next two links:

Harris Educational - Reinventing Science Getting More People INTO Science and Technology: Neil deGrasse Tyson's comments in this PBS Newshour article are very sobering. As you start your new year think about what we all can do in 2010 to help engage more people, promote citizen science, and get more kids involved and interested in science technology engineering and mathematics!

What Were the Science Breakthroughs of 2009?: As 2009 wound to a close, the PBS NewsHour asked scientists and science journalists to discuss the most significant science stories of the year.

One key quote from the article: "But as the years pass America will have descended from leaders to players to merely followers as we fade to insignificance, at best hitching a ride on the innovations of others."

Not that America has to lead at everything, but I really do think we are loosing a vital part of what has made us who we are. He likens ... See Morethe change not as falling over a cliff, but as a slow slide downhill. And slow slides are the most dangerous because they do not register as imperative in our perceptions.

But its not too late for us all to get involved, do a project, build something, help kids to learn to love asking questions (even hard questions).

Harris Educational - Reinventing Science 3D Printing: We've covered all kinds of 3D printers and CNC machines this year, but this one tops them all, a Biological Printer for building custom tissue out of living cells. Its just a prototype but could offer surgeons replacement tissue for all kinds of surgeries.
(via Gizmodo)

Or, as they call it, a "3D bio-printer." Essentially, it allows scientists to build tissue cell by cell. It's that cool sci-fi medical stuff we all dream about.

The project, hosted at ibiblio, is a fully open source virtual Apollo Guidance Computer. A great tool to learn about early computer hardware and software, or for anyone who is REALLY REALLY interested in the technology of the moon landings.

Harris Educational - Reinventing Science
This is the same design philosophy I had when creating my "Reinventing Science" kits. I wanted a science kit that would not only teach science, but integrate history as well AND let the experimenter actually do a science experiment (i.e. try different things and note the differences) not just demonstrate a science principle (i.e. the old make a ... See Morecircuit, look when I flip the switch the light comes on) method. I've been to science educational conferences surrounded by all kinds of modern lighting, and the teachers knew what would happen when they applied voltage to a simple piece of pencil lead in my Reinventing Edison kit, but even so jaws never fail to gape and I always hear "wow". We need to return to an "I can do this myself" "lets get my hands dirty" and "I want to know how that works" mentality in this country. Some people have it, but far more could become excited if the material was presented in the right way. Comparing older designs to modern technology is one way of making the technology and science more accessible and fun.

Shockley was not present during the "discovery" of the transistor. The picture is a false, staged depiction of all three working on the device.

Ira, you are correct. Most of Shockley's ideas were proving not to be workable and the most productive time in the lab was during his absence. Even once they'd demonstrated the first workable transistor they found out that someone else had already patented some of the ideas earlier in the 1930's! Just like most of history, science history is ... See Morefilled with urban legends and popular misconceptions. Just like Edison and the Light Bulb. He really didn't "invent" the bulb, he just beat a less profit-driven scientist from England named Swan to the patent office. And even then both were working on an idea that had been demonstrated decades before.

It is possibility natural to think of such a skill as 'old-fashioned.' But the reality is that there is math and science input in this and other skills, as well.
