+ - Bird flocks resemble liquid helium->

Submitted by sciencehabit
sciencehabit (1205606) writes "A flock of starlings flies as one, a spectacular display in which each bird flits about as if in a well-choreographed dance. Everyone seems to know exactly when and where to turn. Now, for the first time, researchers have measured how that knowledge moves through the flock—a behavior that mirrors certain quantum phenomena of liquid helium. Some of the more interesting findings: Tracking data showed that the message for a flock to turn started from a handful of birds and swept through the flock at a constant speed between 20 and 40 meters per second. That means that for a group of 400 birds, it takes just a little more than a half-second for the whole flock to turn."

Been meeting with the same group for more than 30 years now on Saturday night. I started playing the when the 1st red-book with crayons came out, I was like in 6th grade, and yes I still have the boxed set and nearly EVERY other book, module, and accessory. I'm 46 now and NO other form of RPG online or other can compare to the fun and comradeship of a face to face pen and paper RPG. More imagination, more interaction, and for those of you who doubt it is family fun, our group consists of 2 single ladies, 3 single guys, 2 married couples all my relative age (mid 40's) and 3 much younger players in their mid 20's ( 2 guys and a girl. We have 3 players who rotate as Game Master and we play in a long standing organically customized world. We have been at several Gen-Cons and we ran a full tourney game that was very successful several years ago.
Long live D&D

and if I visit a retailer that won't accept cash you lose the sale. I have credit and debit, but I prefer to pay cash for what I want. As for the criminal economy, I'd say corporate America is doing just fine with credit and cash. I also do a healthy side business dealing in barter for services, even more anonymous and generally tax free.

Do you have experience that points to other sources ? I've done this for several years now and I've yet to have to work a teachers or admins workstation for anything but a part failure, while I spend more time cleaning up student workstations and shared library stations with the software filter and the tampering students...

NOTE : quite often I learn NEW and interesting things fixing stuff after the kids are done, things I never would have considered or thought of trying :)

WOW I wish more people thought like you. I volunteer and manage a network and wireless setup for a high-school in my area, the bandwidth is provided free of charge by AT&T, I know it surprised me as well. Kids can and DO break things in ways I never even conceived of before taking on this responsibility. I work as an admin for a very LARGE business and do this professionally and I've never seen the cluster-fsck that 2 dozen high school kids can make of a network in 10 minutes without even really trying.
Hardware and software companies need to get these kids to be beta testers.

and ensure the cars are safe, registered, and are not ripping people off ? "Haven't we been around the park already driver....?" While I agree cabby licenses DO restrict who can run a cab or taxi, without some regulation you will soon be riding in a car you'd see on the road in India. I've been a cop and inspected cabs for the county. The owners and drivers of cabs would do without insurance, seatbelts, windows, doors, tread on tires, ANYTHING to make a buck.

Individuals who are on call need to make sure they go places they are open to cell phones, much the same way they need to remain within a certain distance of their work. Why should the rest of the world suffer for these few special needs individuals ??
My house is an AT&T black-hole anyways. I had to switch carriers after many complaints because I couldn't receive call in the back of my house. Verizon has NO SUCH problem in this area apparently.
