Freebie Friday Roundup

Freebie Friday Roundup: Optics, Sand, The Jetsons, Peanuts, and Calvin & Hobbes


A great hands-on experiment & study guide from NASA filled with great color and light activities using lenses, prisms and mirrors to create telescopes, periscopes, microscopes and kaleidoscopes. Other activities include finding focal length and understanding reflection, refraction and diffraction. Activities are marked by grade level, and can be adapted from K-12 (so they say). Anyway, this is a lot of fun!

IT’S A JETSONS WORLD by Jeffrey Tucker (PDF ebook)

Today we feature this fascinating economics book, just published by the Mises Institute book for junior high – adult readers on how free market has changed our lives today,  particularly in the digital universe, and yet we don’t appreciate or realize this nearly enough. Meanwhile, the public (government) sector is systematically wrecking the physical world in sneaky and petty ways that really do matter.
Easy to read, full of great stories, and written with an Austrian School of economics viewpoint, this book is and eye-opener for older students and parents who want to gain a better understanding on the changes in our world today and in the years ahead.

The pace of change is mind-boggling. The world is being reinvented in our lifetimes, every day. Email has only been mainstream for 15 years or so, and young people now regard it as a dated form of communication used only for the most formal correspondence. Today young people are brief instant messaging through social media, but that’s only for now, and who knows what next year will bring.
Oddly, hardly anyone seems to care, and even fewer care about the institutional force that makes all this possible, which is the market economy. Instead, we just adjust to the new reality. We even hear of the grave problem of “miracle fatigue”—too much great stuff, too often. Truly, this new world seems to have arrived without much fanfare at all.

The Jetsons’ world is our world: explosive technological advances, entrenched bourgeois culture, a culture of enterprise that is the very font of the good life. But there is one major difference, and it isn’t the flying car, which we might already have were it not for the government’s promotion of roads and the central plan that manages transportation. It is this: we also live in the midst of a gigantic leviathan state that seeks to control every aspect of our life to its smallest detail.

The government, however, is still the Flintstones, an anachronism that operates as this massive drag on our lives. With its money manipulations, regulations, taxation, wars (on people, products, and services), prisons, and injustices, we similarly look the other way. We try to find the workaround and keep living like the Jetsons.

Well, not quite… but today we feature something completely different: Here from the Experimental Theology blog is a playful and thoughtful “young-reader friendly” online book of theology lessons derived from none other than Calvin & Hobbes. “How can this possibly be?” you ask. Well, give it a look-see. Regardless of your theological persuasion, this contains some fascinating material (AND great cartoons) for young and old readers alike.
