Scientific American magazine catches the April Fool's spirit

Okay, We Give Up

SciAm Perspectives Column

There's no easy way to admit this. For years, helpful letter writers told us to stick to science. They pointed out that science and politics don't mix. They said we should be more balanced in our presentation of such issues as creationism, missile defense and global warming. We resisted their advice and pretended not to be stung by the accusations that the magazine should be renamed Unscientific American, or Scientific Unamerican, or even Unscientific Unamerican. But spring is in the air, and all of nature is turning over a new leaf, so there's no better time to say: you were right, and we were wrong.

In retrospect, this magazine's coverage of socalled evolution has been hideously one-sided. For decades, we published articles in every issue that endorsed the ideas of Charles Darwin and his cronies. True, the theory of common descent through natural selection has been called the unifying concept for all of biology and one of the greatest scientific ideas of all time, but that was no excuse to be fanatics about it.

Where were the answering articles presenting the powerful case for scientific creationism? Why were we so unwilling to suggest that dinosaurs lived 6,000 years ago or that a cataclysmic flood carved the Grand Canyon? Blame the scientists. They dazzled us with their fancy fossils, their radiocarbon dating and their tens of thousands of peer-reviewed journal articles. As editors, we had no business being persuaded by mountains of evidence.

Catching ID thieves yourself

Here's a fascinating blog post by "Ovid" on how he caught his ID thieves in only a couple of hours. They had racked up a few thousand dollars of charges on his credit card. Maybe Ovid should be a detective, although he did get a couple of lucky breaks. Of course, the credit card companies would never have held him responsible, but it must feel good to personally catch the bad guys. His story is also being discussed on this Slashdot thread.

A PPU (Physics Processing Unit) Card

The first generation of PPU cards are coming to market. Anandtech is reporting on the PhysX PPU card from AGEIA.
Just like GPU cards which added 2D graphics acceleration and later 3D, PPU cards will accelerate physics (no pun intended :-) calculations. Software developers can use the PPU cards to do much better physics simulations without running out of processing power in the CPU.

Credit card signatures don't matter

When he got frustrated John Hargrave drew a picture of Shamu instead of signing his name on a credit card receipt. The cashier accepted this without even blinking. Surprised, he decided to find out what it would take to have someone refuse to accept his credit card becuase of a mismatched signature.

It get's pretty ridiculous towards the end, but he finally does manage to get someone to refuse to accept his card.

How to destroy the Earth

Sam Hughes maintains a detailed analysis of what it would take to destroy the Earth. Needless to say it's a lot harder than most sci-fi movies make it look.

His mission statement for the analysis is:

For the purposes of what I hope to be a technically and scientifically accurate document, I will define our goal thus: by any means necessary, to render the Earth into a form in which it may no longer be considered a planet. Such forms include, but are most definitely not limited to: two or more planets; any number of smaller asteroids; a quantum singularity; a dust cloud.

"Donald Knuth is legendary in the computer science world for writing a series of must-have reference books called The Art of Computer Programming. Part cookbook, part textbook, part encyclopedia, these books are also considered by many to be technical and personal works of art."
