Instant Kool-Aid!

Well, not quite. This is what’s apparently called an Iodine Clock Reaction. It’s a classic experiment where you mix two colorless chemicals and then after a short delay, it instantly changes color. You can even do this safely in your own home either by using common store-bought chemicals or buying a kit designed especially for […]

Ruben’s Tube

There’s a good chance that this is just a crazy guy setting fires in his garage, but there’s an equally good chance that he’s teaching us something about physics. The Ruben’s Tube was invented in 1905 by a German Physicist named Heinrich Rubens. It’s purpose is pretty clear, to visualize sound waves using many small […]

Ruben's TubeThere’s a good chance that this is just a crazy guy setting fires in his garage, but there’s an equally good chance that he’s teaching us something about physics. The Ruben’s Tube was invented in 1905 by a German Physicist named Heinrich Rubens. It’s purpose is pretty clear, to visualize sound waves using many small flames, though I can’t imagine how he came up with the idea.

Not only that, imagine hearing about this in 1905. Your friend tells you about some sort of mad scientist who is using fire to visualize a invisible shape that accompanies sound wherever it goes. I wouldn’t know whether to be afraid of what else this man is capable of or in awe of his super-human control of the elements. Anyways, enjoy the modern day execution of an old experiment.

Premium Telescope Technology

Here’s a neat video that shows of the functionality of a Large Binocular Telescope. It uses twin sets of multiple mirrors that bounce images back and forth until they have a clear picture of what they’re looking at. This really seems to …

Fermi at Five Years

Fermi is a space observatory launched by NASA in June 2008 that has been used since then to observe happenings in all reaches of space. It is loaded with instruments, most importantly a telescope and a Gamma-ray Burst Monitor and with these instruments NASA has been able to make many discoveries over the past five […]

This video outlines several of these discoveries that have taken place at varying distances from Earth.

It’s a pleasure to be working with entire staff of the Prairie Lake Area Education Agency about education today. I suppose that one of the characteristics of this day and time is that geography and zip code mean far less than they ever did before, that there is practically nothing that you can do for anliving in New York City that you can’t do from your home or rent-an-office in Prarrie Lakes.

This all assumes that you have the skills and the knowledge, and the skills to gain the knowledge, to work in a transparent world.

Hitchhike to PodCamp

The first PodCamp happened this weekend at Bunker Hill Community College in Boston. A BarCamp-style event, podcasters from all over the Boston area (and beyond) came together to geek-out, and learn from each other.

It was one of the most richly blogged and podcasted events I’ve seen on hitchhikr, and it’s be a joy to watch and continue to study. Drew Olanoff, of Drew Olanoff, Unpluggd said,

Media treats us like numbers. New Media treats us like people.

Drew Olanoff, Unpluggd. » podcamp – the revolution WILL be televised…on the net.

Read that and think about what kids think about today!

Catch the conference on hitchhikr at hitchhike to PodCamp Boston. The conference also made excellent use of a wiki for their conference web site with a page devoted to recordings made at the conference. Have a visit.
