Richard Feynman is his book "Surly You're Joking Mr. Feynman" relates how as a boy he was able on one occasion, at night, to tune-in WACO AM in Waco, Texas. This was/is possible because of the ionosphere. Due to the nature of the ionosphere radio signals are reflected to a greater degree during the night. Indeed, AM stations will be assigned a diurnal maximum power of transmission, and also a nocturnal maximum power of transmission. The former being greater than the latter, as the reflectivity of the ionosphere is greater during the night. For a more detailed explanation see: www.hfradio.com/qst.pdf.

"Or even just nuking your lawn and putting in wild flowers or a rock garden? You'd be amazed how much pollution the average picket-fence-and-one-point-five-kids lawn contributes to your local watershed in the form of storm runoff becuase of all the crap you have to put on it to make it look "nice" ("nice" here evaluating to the traditional standard of perfection and control accepted by society, not natural chaotic beauty). You need to evaluate your real goals; is your priority the environment, a nice lawn, or no time spent on lawn maintenance."
StandardDeviant has a good point here.
The standard lawn is a water hog. For some locals, such as the ones that most turf verities evolved in, this is not a problem. However, in most areas of the US the turf species that are commonly used for lawns are anything but well suited for the climate.
In the summer the bulk of residual water usage in Dallas, Texas is for lawns. This has caused the City of Dallas to come into conflict with cities, and counties in East Texas over water rights. The solution for Dallas is not to try to "steal" water from other areas of Texas, or even Oklahoma, or Arkansas; but to start placing restrictions on water consumption. A possible alternative to mandatory restrictions is to have Dallas residents pay, out of their own pockets, at a rate that reflects the true value of the water that they're using to the cities, and countries of East Texas. In any case folks are going to have to start learning to adapt to the climate that they live in, rather than trying to impose their aesthetics on the local environment.
Both PASCO & Vernier offer Macintosh software for their hardware. Much if not all of their software will work with Mac System 6.08 through MacOS 9.2, and I believe in Classic mode under MacOS X. My suspision is that your school might have an older Mac lurking about in the wings. If so, then you could download the PASCO software that would work with that old Mac.

If nature has made any one thing less susceptible than all others of exclusive property, it is the action of the thinking power called an idea, which an individual may exclusively possess as long as he keeps it to himself; but the moment it is divulged, it forces itself into the possession of every one, and the receiver cannot dispossess himself of it..... and like the air in which we breathe, move, and have our physical being, incapable of confinement or exclusive appropriation. Inventions then cannot, in nature, be a subject of property. --Thomas Jefferson
I've got a G3 (Pismo), and find that the track pad is ok for general use. However, If I'm going to be doing a lot of word processing, spread sheet work, etc. I'll hook up. my Logitech Marble Mouse (Part Number 904360-0403) as I prefer a trackball to the track pad, or to a mouse for that matter.
The nice thing about OS X is that it supports two button mice/trackballs natively, so the second button will function ! right out of the box. I have a G4 Sawtooth at home. I'm using a Kensington Turbo Mouse PRO with it. The software that Kensington makes for it gives it functionality I find quite helpful when dealing with large projects using productivity software. The only reason that I've gone with the Logitech Marble Mouse for my Pismo is that the Turbo Mouse is just two bulky for convenience when transporting a laptop.
To conclude: I prefer a trackball over all other similar input devices. I find that I've no preference when it comes to mice, and track pads.
Theft is it? Consider the following from Thomas Jefferson's Letter to Isaac McPherson dated: 13 Aug. 1813
"If nature has made any one thing less susceptible than all others of exclusive property, it is the action of the thinking power called an idea, which an individual may exclusively possess as long as he keeps it to himself; but the moment it is divulged, it forces itself into the possession of every one, and the receiver cannot dispossess himself of it. Its peculiar character, too, is that no one possesses the less, because every other possesses the whole of it. He who receives an idea from me, receives instruction himself without lessening mine; as he who lights his taper at mine, receives light without darkening me. That ideas should freely spread from one to another over the globe, for the moral and mutual instruction of man, and improvement of his condition, seems to have been peculiarly and benevolently designed by nature, when she made them, like fire, expansible over all space, without lessening their density in any point, and like the air in which we breathe, move, and have our physical being, incapable of confinement or exclusive appropriation. Inventions then cannot, in nature, be a subject of property. Society may give an exclusive right to the profits arising from them, as an encouragement to men to pursue ideas which may produce utility, but this may or may not be done, according to the will and convenience of the society, without claim or complaint from anybody. Accordingly, it is a fact, as far as I am informed, that England was, until we copied her, the only country on earth which ever, by a general law, gave a legal right to the exclusive use of an idea. In some other countries it is sometimes done, in a great case, and by a special and personal act, but, generally speaking, other nations have thought that these monopolies produce more embarrassment than advantage to society; and it may be observed that the nations which refuse monopolies of invention, are as fruitful as England in new and useful devices."--Thomas Jefferson
" Remember in the bible something about it being harder to stuff a camel's ass through the eye of a needle than getting a rich man into heaven?"
For the sake of completeness:
It is easier for a camel to go through the eye of a needle than for a rich man to enter the kingdom of God." They were even more astonished and said to Him, "Then who can be saved?"Looking at them, Jesus said," With people it is impossible, but not with God; for all things are possible with God." --Mark 10:23-27 NASV
I don't get my nose out of joint over typos, etc., however I do compose my posts using a word processor (Either Nisus, or Word X). I find that in doing so that most of my post are free of obvious errors. I guess that I'm being a bit too particular in my posts, but it's really not that much extra effort.
I minored in math and I'm not sure just what is meant by Pi in the fourth dimension. By definition a circle is a two dimensional object. By definition Pi = C/r where C is the circumference of the circle, and r is the radius of the same circle. Therefore Pi by definition is the ratio of two properties of a two dimensional object.
Which leaves me (or us) with the question of what does the fourth dimension have to do with the value of Pi?
"I've seen have used membrane technology, but I have always been a believer that ergonomic keyboards not only hinder a typist, but also do not relieve any stress from typing. I never proved that of course, but I've always felt more "natural" with standard keyboards. An article was just released at the BBC, describing how ergonomic keyboards might not be as helpful as many might hope to believe."
As fate would have it, I'm a big guy. I wear either a XXLT or XXXLT shirt. Given that I have broader shoulders than most, I find that an ergo keyboard to be very much more comfortable than regular rectangular keyboards.
I *suspect* that there's a number of variables that play a role in whether or not a person finds ergo keyboards to be a significant improvement over conventional keyboards.
"In other words, I was correcting your fallacious argument (implied by your false equivalence between different motor fuels) by using a more precise definition. I plead nolo contendere."
My argument was, and is not fallacious. Say it aloud -- *context*.
You equivocate the technical use of --efficient-- with the colloquial use of --efficient-- and therefore create an argument based on semantic confusion. There was no false equivalence, on my part, between motor fuels, as I clearly stated: "Diesel fuel has a higher energy density than gasoline. On average, 1 gallon (3.8 L) of diesel fuel contains approximately 155x106 joules (147,000 BTU), while 1 gallon of gasoline contains 132x106 joules (125,000 BTU)." Clearly 147,000 BTUs *>* 125,000 BTUs, and thus I made no statement of equivalency between gasoline, and Diesel. Undeniably, I showed that there was an inequivalency between the two fuels.
Again my statement was based on the colloquial used of efficiency: mpg (km/L). Thus, in the context of the discussion my statement stands.
If you were to say that your computer is speeder than my computer based on the fact that your processor runs at twice the MHz as mine you would be using a colloquial definition of --speed--. In point of *technical* fact you would be incorrect as MHz is a unit of frequency rather than velocity. Unless your computer was/is a laptop then the speed of your computer, in general, would be zero mph, k/s, etc.. However, your statement in all likelihood would have been made in a colloquial *context* and thus in that context would NOT be false.
Statements take out of context almost always can be "proven" false.

0 to Mach 5 in 15 seconds?
That's going from 0 mph to 3700 mph, or 0 to 5400 ft/s in a quarter of a minute; assuming 740 mph = Mach 1.
a = [v(2) - v(1)]/delta t
a = (5400 ft/s - 0 ft/s)/15 s = 360 ft/s^2
