Re: Wireless Power Nearly There

A new market for: Wireless Power Noise Cancellation Devices! Yes!

Oh wait, those will probably require power too... NOOOO!!!!

Yeah, that's the sort of thing I thought back there in the '80s. I couldn't think of exactly how to build a sure-fire version of such a gadget though... although I never actually got as far as, e.g., sketching up some plans or finding a flag pole to experiment on! :-)

Where did you obtain a sufficient quantity of foam on a student's generally limited budget from??? I'm just thinking that, these days, with a single can of expanding foam being $5/can...

Some of that linked article do tend to suggest this, with their "cell phones use algebra to process signals, blah, blah" bit... True, I suppose, but suggesting someone with only a high school algebraic background is fully equipped nderstand all the fancy encoding and error correction schemes used in a contemporary cell phone is nuts.

What I take offense at is "teaching" Calculus in high school. With no need for application, none of it sticks.

I prefer MIT's method of teaching it _exactly_ in parallel with the need for it in Physics.

I do take note that this morning's news says SAT scores are at their lowest in history :-(

Cool. I definitely was born a bit too late for some of those sorts of shenanigans. :-)

Of course, plenty of new forms have sprung up over the years...

What would have been even more fun would to have a radio controlled latch & spring to fling it off the pole when they went to get help to remove it. That way you could put it back as often as you wanted to. ;-)

Sleeping: Z = 0

Programmers probably use algebra less often than plumbers.

They put it on TOP of the flag pole. I can understand how to just hoist it up... but on TOP ????

You should be careful not to play the nutcase too often, else you could be mistaken for one.

Any time you declare a variable, and do some operation on it is algebra. Even the registers in you pre-historic CPU are the incarnation of variables.

Absurd. Look up the definition of algebra.

But there's not a lot of point in arguing definitions. Nor is there a lot of point in calling practically everything that deals with numbers "algebra."

Stuck on the top, upside-down. Supposedly a regular trash can (e.g., 30 gallons).

Perhaps some college buddy of his was in the national guard and had access to a chopper? :-)

So: int a;

a = b * CONSTANT;

is algebra;

If your registers are called R1, R2, etc.. then any opertion on thsoe is pure algebra.

For example add r1 to r2 and out the results in r3, is THE SAME as r3 = r1 + r2, is the same as c = b + a;

Come on, Jim. There is always a way, when a good practical joke is at stake. It wouldn't be much different than one of the telescoping pole saws.

What does that have to do with science illiteracy? It sounds like you're proposing that students should be taught even less. The point his nto at all wheterh "too many" kids go to college, the point is that students are just taught to memorize'n'regurgitate, rather than examine and analyze. ((And since I'm sure thre will be something brought up regarding students with limitations: even students with limitations should IMO be taught to make the best of their abilities.))

One deos not have to be college bound to be taught the basics of how the world works. A mechanic, for example, has to have an understanding that things work for a reason. IOW, even vocations require skills, including thinking skills.

An understanding of how to solve certain problems is not useless. The only problem with teaching math is that it's almost never applied to real-life situations, but instead is presented as nothing more than "you're taking this because we tell you to", as nothign more tahn a theoretical exercise, some abstract bit of nonsense. That illustrates the almost-never-mentioned difference between teaching, and educating. A teacher stands up in front of the class and basically gives speeches, whereas an educator shows students (of any age!) how the topic at hand ties in with real life.

So sorry, but I don't think it's "bad" to introduce 8th graders to algebra (heck, when I was a kid, they started with teh basic concepts of equations in 6th grade). What's "bad" is when math is treated as being "just one more BS thing to deal with so as to get through school".

Speaking of pole saws, I have a new gadget... an electric chain saw (battery-powered, Black & Decker) on a pole. Now I can trim my own trees with minimal climbing. Really easy to use and it's light weight.

I thought of that as well those 20+ years ago. At the time I was always trying to have it doable with a single person, which seemed pretty much impossible in that no single person is likely able to hold a 40+' pole all by themselves, but perhaps with multiple people you could just have 3 or 4 additional individuals with guy lines to stabilize it as you erected it the full length -- I've seen ham antennas raised this way. A bundle of the old military fiberglass antenna masts that are 6'? each would be reasonably compact and easy to transport and erect, perhaps.
