OK, putting all the snarky, sophomoric thoughts aside, the USAF *should* be doing this sort of thing. It's the ultimate in military intelligence, finding out who's out there, how far away "they" are, and making an estimate of what nasty things they might be capable of doing to our species. (Oh, and I worked doing operations planning on the old NASA SETI Program in the 1980s, and I came at SETI from two points of view: One was for the pure science of finding out more about our Universe, but the other from the point of view of military intelligence, on the periphery of which I worked a decade earlier.)

I teach at a small charter high school here in N. AZ. Aside from grading papers, the bane of my existence is that students come to school WITHOUT so much as a single pencil with which to write! They have their cell phone, they have their cigarettes and lighter, and they can afford piercings and tattoos, but not a single pencil! WHAT was that "teacher" thinking?

http://www.jamesbrennan.org/algebra/ Nicely done Algebra 1 text. No problem set, however. http://cnx.org/content/m19435/latest/ Don't let the somewhat klutzy organization of this text put you off. What this guy is doing is running you through Algebra 2 by discovering it for yourself. This is the text I use at the small charter school where I teach, and it's working well with kids who have never, ever gotten school at all! Good luck to you.

OK, at the time of that article, the Internet had already become much more than a novelty. Newsweek just didn't notice. And I'd have to agree that the Internet had NOT become a necessity. I'd even agree that, if the Internet isn't available to me for say, 48-hours, it's no biggie. I'd just have to deal with a bunch of emails that have been accumulating. However, if the Internet as a whole went down for an extended period of time, there would be hell to pay. Just look at the economic consequences to businesses in Egypt when that ship hit and cut an undersea cable carrying much of the Internet connectivity between there and Europe. It wasn't pretty for them....

So, this works for Alice and Bob. What about Homer and Jethro?

We already have something that will allow folks to evaluate information from multiple sources. It's called an EDUCATION! We're just doing a piss-poor job of it.

Well, what we need is twofold: (1) A Prime Directive, and (2) A permanent prohibition of William Shatner entering outer space!

Have any images exploded due to this glitch? When will the recall be announced?

I worked on the NASA SETI Program in the 1980s in the Deep Space Network at NASA/JPL in Pasadena, CA. I led a small team of engineer/astronomers who provided a wide variety of planning, scheduling, and execution of radio astronomy and radar astronomy experiments withing the DSN. Sometime during that time, a senior manager of SETI, N. A. Renzetti, arranged for the late Dr. Philip Morrison to meet with my team and a few others one afternoon. There was no particular agenda, but we understood that we were there to hear about Dr. Morrison's opinions about SETI. One of my colleagues asked what his definition of life was. He replied that, boiled down to its essentials, it was the ability to reproduce. He then mentioned, almost in passing, that he had heard from a geologist at MIT about a particular variety of clay that, if given the right raw materials, could reporduce itself, but, if the raw materials were present, but the clay was not, no clay would be produced. I asked the obvious question: "How was the original batch of this clay produced?" Dr. Morrison replied that he really didn't know, but made a joke about chickens and eggs.... I've occasionally wondered about that clay over the years. Has anyone else every heard of this (possibly) prolific stuff?

Uh, actually, no airfoil, either fixed or rotary, generates lift. For example, the wing of an airplane sitting on the ground generates no lift unless air is flowing over it. A frisbee sitting on the ground is just the same. Only when the person flying it imparts a force to it does it "fly". Another way of looking at this is to hold a frisbee at shoulder height in a horizontal position and then drop it. It will float in a semi-stable position down to the ground, because it has a large cross-sectional area WRT its mass. Do the same thing, but give it a bit of spin, and it will float down very smoothly. It's behavior is no different from a parachute, with the exceptions that parachutes aren't designed to spin, and you don't strap it on!

Everything has its place, and the Aerobie's place needs to be really BIG, because they fly faaaaaaar! Alan Adler, the (extremely clever) inventor of the Aerobie flying ring, recognized this when he came out with his own line of flying disks. True to form, they fly really, really well!

I never had the pleasure of knowing Mr. Morrison, but I played various frisbee-disk games for a lotta years, and even played flying-disk golf at the pro level for a while. But I had a real job, so left the ultra-serious play to other, better players. I heard various stories about Fred over the years. All seemed to indicate that he was friendly, very straightforward man. I was told once that he had bought a hardware store in the early 1960s in Sierra Madre, CA. Folks asked him why he was going to his hardware store every day if he was making so much money in royalties from frisbee sales. "Well, I like owning my own hardware store!", he replied. I really can't prove this story to be true, but if it's not, it oughta be! Thanks for the revolutions, Fred! Adieu.....

OK. This is a serious breach of decorum. It's Frisbeeterianism, with a capital "F"....

It used to be that the big error of many scientists was to make studies of studies. Now, it appears that studies of news reports of studies are becoming acceptable. Are climate scientists the mysterious "they" that they're always talkiing about?
