Flickrvision is a mashup of Flickr and Google Maps. Strangely addictive. Better than television.

6-bit binary adder

Here is a 6-bit binary adder built out of wood. It uses marbles for bits, and gravity for power. Cool! And it doesn’t crash as often as Vista.

How early could something like this have been built? The Greeks could certainly have managed the construction; the Antikythera device (100 BC or so) is much more complicated. Binary arithmetic, in its modern form with the ones and zeros, dates to Leibnitz in 1703. But as far as I can tell, the first binary adders were build out of relays in 1937.

In 1937, Claude Shannon produced his master’s thesis at MIT that implemented Boolean algebra and binary arithmetic using electronic relays and switches for the first time in history.

Turtleope

Someone with a lot of spare time has photoshopped animals with plants. There’s a penguin/eggplant, a horse/tomato, and other strange things. Reminds me of The Island of Dr. Moreau.

If Google Earth isn’t enough for you, there’s Google Sky. Also Google Moon and Google Mars. I just wish it had a flight simulator mode like Google Earth.

I also have a slide show of some non-copyrighted APODs.

Garfield

Garfield minus Garfield is a site that shows Garfield comic strips minus Garfield:

Who would have guessed that when you remove Garfield from the Garfield comic strips, the result is an even better comic about schizophrenia, bipolar disorder, and the empty desperation of modern life? Friends, meet Jon Arbuckle. Let’s laugh and learn with him on a journey deep into the tortured mind of an isolated young everyman as he fights a losing battle against loneliness in a quiet American suburb.

Reason

I’d love to see a Youtube of that sermon!

Reader jde pointed out that Reason and Faith have co-existed quite nicely since ancient times.  He’s right, if by Reason we mean Rationalism.  There is a long tradition of Reason in the service of Faith, say approximately Augustine through Descartes.  We can see a faint reflection of Rationalism today in Intelligent Design.

However, if by Reason we mean Empiricism and scientific method, say Hume forwards, then Faith and Reason are opposed.  The conflict is epistemological;  we can accept revealed truth, or we can follow the evidence, but if they disagree, we have to choose one or the other.
