Cute. Though people could just go ahead and read the article. To wit: Although the telescope would have been able to detect fainter stars, none could be found- so it appears that they simply don't exist. "We checked the instruments over and over again" said Professor Richer "but we don't see any stars fainter than this".
I would agree with the Noether suggestion, except I've no idea how to explain what she did to 5th and 6th graders. Lie algebras? Rings? Action principles in physics, and symmetries? By 5th or 6th grade, they'll have learned about conservation of energy. However, relating that (or some of the other conservation laws) to a symmetry in the action principle is a bit rough.
The fact that Noether was a woman in a somewhat rough time for woman scientists is easy to teach. And the accomplishments of all of the other people on your list can at least be approximated for kids of that age. Still, can't figure out the Noether thing. If anyone has some suggestions, I'd be happy to hear them!
i have fvwm2 fixed up pretty nice with full paging & edge wrap. once you get the hang of it then going back to icons on a taskbar is klumsy and slow...
I'm sorry. "Klumsy" is a trademarked adjective of a different desktop environment. You have been warned.
If nobody knows what dark matter is and if it can't be directly measured or detected then how does one go about measuring its motion and the energy released and know therefrom that it was dark matter that collided with the non-dark matter and not an altogether different unknown substance?
If there isn't a way to find out if it's "an altogether different unknown substance", then, for all intents and purposes (and sanity), it's not.

It usually ends with "Get off my lawn, ya damned whippersnappers!" That's me, not the teenagers. Then they flap their toothy gums around and all I hear is a lot of high-pitched squeaking noises.
TFA is a neat idea theoreretically, but it's progeny will never be able to leave the lab.
Your use of "TFA" is a good compressional technique, but you could change "it's" to "its" and actually GAIN in meaning while losing a character! You're well on your way...
This was referenced in the book Complexity by Waldorf. At least in that context, it was about a competition among computer programs and genetic algorithms. It may also have shown up in Hofstadter's Fluid Concepts and Creative Analogies. Of course, it may have been done far earlier than the mid-80's, but those are the two books I'd look at first.
my point is that apple, and my espresso machine are, if at the very least, exceptions to the rule, they are still examples of a cohesive, seamless, inclusive environment, where everything just 'works', & works beautifully, without necessarily fucking the consumer in the ass.
That review didn't cover the 1920 and 2560 resolutions, but that's where the advantage should be quite significant. Of course, whether it's worth it or not depends on how many more hours you'll have to spend flipping burgers to pay it off.
The computer manager keeps telling me to stay at home. I can't flip the burgers!
Indeed.... But you have an ally toward this problems and its not the police......
It's the RIAA!!!!!!!!!!!
To me, this type of "sharing" sounds like a public performance, which is expressly forbidden under the terms of most copyrights. Furthermore, they may have illegally obtained their music. I'm sure they would be happy to sue/imprision thy neighbor.
I would happily shove burning splinters under the fingernails and toenails of people who blare their music for all to hear, scalp them, and do some really nasty bits with boiling oil and squid. But give them to the RIAA? Now that's just mean.
The "sharing" of music with everyone is one of my biggest pet-peeves. People don't seem to realize that neighbors might want to work at home, and don't want to be distracted with, e.g. loud music of any sort.
Or people have young children who can't sleep with crap blaring; or older people who can't sleep with crap blaring; or, just for fun, how about your friendly emergency room nurse or doctor, who happens to pull a night-shift. When THEY can't do their job effectively because of some asshole neighbor, good luck to you.
Perhaps your neighbors did escalate things a bit much when they called animal control. However, you certainly didn't help things by keeping the whole damned neighborhood awake and crabby. Nice job.
I'm glad that police here take noise complaints seriously, no matter what time of day they're reported.
Use 2 different directional high frequency (ultra sound) drivers pointed at his house from two different places but focused at his mosquito device. One at 38kHz the other at 40kHz. Where the two wave fronts meet there will be a loud interference tone of 2kHz.
This is a well-known technique, and all sorts of audio people have gone bonkers over it in the last several years. It was published by Blackstock and someone else in the mid-70's (at least that the effect can occur in air), and essentially uses some tricky "breakdown" of the usual linear soundwave behavior in air. I've seen it in action (a demonstration show several years ago) where a guy with a relatively small parabolic reflector was able to aim a soundbeam at various audience members. No one else could hear the sound when the thing was pointed at you. Impressive.
However, it's technically kind of tricky, and requires some non-inexpensive transducers to effect it. And if your neighbor (or the police) isn't very near his mosquito repeller, what good will it do you?
Ah. If you're talking about the pseudo-repulsive potential mentioned in the article (away from the barycenter), fine. BUT the sum of conservative potentials (as the 1/r and 1/r^2 ones are) is also conservative, and will STILL lead to elliptical orbits in general. So you've got to propose some non-conservative forces acting, and then you can't even really use "potential" in its usual sense of leading to a force via the gradient.
Whoa. What's the repulsive 1/r^2 "centrifugal" potential? At first I thought you were including G.R. with the talk of tidal forces, but then I realized (via the 1/r potential) that you're talking about regular old Newtonian gravity. That's fine. But where's the repulsive potential?
The only tidal forces I can see in this problem are evinced in the deformation of the earth or the moon, their atmospheres, and the ocean of the earth. Wikipedia has this to say about tidal locking:
There is a tendency for a moon to orient itself in the lowest energy configuration, with the heavy side facing the planet. Irregular shaped bodies will align their long axis to point towards the planet. Both cases are analogous to how a rounded floating object will orient itself with its heavy end downwards. In many cases this planet-facing hemisphere is visibly different from the rest of the moon's surface.
The orientation of the Earth's moon might be related to this process. The lunar maria are composed of basalt, which is heavier than the surrounding highland crust, and were formed on the side of the moon on which the crust is markedly thinner. The Earth-facing hemisphere contains all the large maria. The simple picture of the moon stabilising with its heavy side towards the Earth is incorrect, however, because the tidal locking occurred over a very short timescale of a thousand years or less, while the Maria formed much later.
I'll have to try to work out how tidal forces within one astronomical body might lead to a circular orbit. It might be a well-known effect, but it's not obvious to me.

They left the experiment a little to close to a potatoe. (All members of the nightshade family have a missing vowel in their outer shell.)
And is your "too" repository also grown from nightshade stock?

I know these laptops are built to be rugged, but is it really a good idea to send them flying through the air?
It's all the rage. Jon-Benet's killer was apparently doing it there, too.

No please get rid of Insert, I would give blood, sweat and tears for that!

LOL. Best. Post. Ever. Especially after the whole "Compress Wikipedia and Win Big!" story.
You don't talk with teenagers often, do you?

I hope the prize fund becomes very large and someone like you comes up with an algorithm and gets rich enough to retire.
Yeah, me too! For large "me" values of "you".

Well, that was a totally non politically-correct thing to say.
my point is that apple, and my espresso machine are, if at the very least, exceptions to the rule, they are still examples of a cohesive, seamless, inclusive environment, where everything just 'works', & works beautifully, without necessarily fucking the consumer in the ass.
>And it was beautiful.
Uh huh.
I would say that this probably matches a ton of the Slashdot people.
Nice pun, intended or not.
Make sure to use protection, Slashdotters!
oh wait....
Yes, I think you caught the redundancy inherent in that statement, didn't you?

Have a lot of copies of "The Scream" hanging all over?
And yet, the effect claimed has nothing to do with atmospheric drag, nor any magnetic induction.
