Subject: Someone is in need of your help

To whom it may concern,

Greetings to all of you. My cousin Jenny Monta?es, 10, is currently being confined at the Bagbaguin Family Hospital in northern Caloocan for cases of mailgnant brain tumor. At the moment, we may not be able to pay all the incurring expenses brought about by her upcoming brain operation within November.

Unless you will help us in saving the life of this little girl. If deemed possible, you may deposit your cash or check donations to the nearest UnionBank of the Philippines branch in your area (or do an electronic funds transfer if available in your locality), under the following account parameters:

Savings Account number: 00-594-503125-7
Account Name: (plaese write your name under that field)

This is an URGENT CALL for your pledges. And she means immediate. Jenny will be waiting for your kind-hearted donations, so that her speedy recovery will be assured, and her dreams will be fulfilled to the fullest. And by the way, you may even pass this message to your friends or officemates if you prefer to.

Thanks in advance for your understanding and help, and may the continuous grace of our Lord Jesus Christ be with you all.



Respectfully yours,
(Sgd.) Maybelle C. Garcia

I do know that one of the
showmen of electricity was a guy called Michael Faraday.

Ah, yes, the inventor of the dynamo.

"J. Pinkston",

Correct me if I'm wrong, but didn't Ben Franklin,

I think Ben's only static generator was out of service when it wasn't raining.
The first capacitors were called Leyden jars, I think that's the name of the
town were they were invented. Even though I taught electronics for seventeen
years we unfortunately had to skip over the wonderful stories of discovery that
used to be part of such courses. They could be inspirational and spark (pardon
the pun) the student's interest because they were about the real world. I can't
even think of which country the town of Leyden is in. I do know that one of the
showmen of electricity was a guy called Michael Faraday. I know he was a showman
because the most often shows him in a very showmanship like pose. Anyway, the
unit of capacitance was named after him, the Farad is one gigantic unit. The
largest capacitor I've seen in terms of capacitance was in the hundreds of
thousands of micro farads. Or say 0.1 to 0.2 Farads.

Maybe it was because it was a static charge, like we get in the winter

from

walking on carpet. I guess I'll have to look back at his experiments.

Exactly, and a charge can only accumulate on/in an insulator.

I'd like to know, myself, why people think that the charge is stored in the dielectric. It's stored on the plates, the dielectric just facilitates electron transfer.

Correct me if I'm wrong, but didn't Ben Franklin, when he was doing his
experiments with electricity, put to plates close together hooked up to his
static generator, & charge them? That part I'm pretty sure is true. But it
seems like he then could take one of the plates away for a while & when he
put it closely back together he could then discharge it. If that's true, how
could the charge be stored in the air separating the two, especially when
the air was circulating, which I'm sure it was? Maybe it was because it was
a static charge, like we get in the winter from walking on carpet. I guess
I'll have to look back at his experiments.

It's just that ... I couldn't keep quiet. I just HAD
to stand up and say "hey, wait a minute". In defense
of all the many (true-meaning-of-the-word)(good

Especially for the sake of the many "newbies" out

That's all!!

Thanks for your comments....

that person is a victim he will probably make it seem

Subject: Re: [Electronics_101] Fw: communication concepts ??

I personally think that electro-magnetism is a force, therefore electromagnetic waves = electromagnetic force. and force can travel thru vacumn, thats how our rockets flies to the moon.

Rockets travel though space because for any force there is an equal but opposite force. Thrust from the rocket engine is focused in the opposite direction the rocket needs to go. ?This in turn forces the rocket forward. But the force itself is not propagated though the vacuum.

Talking about force, I?wonder if a rocket could fly across a vacumn, which does not have anything at all. I just wonder how could force produce motion if there's no friction for it to force a motion.

?

Is outer space a vacumn?

i m very thankfull to all of u for reply to my message "hacking"
but i think that u can't understand me what i want.
i just want to know "how it can happen" i don't want to do it my self

i appreciate all of my freind's advices which they give me about this
and i hope that they will help me in future also.

There are a great many websites that are devoted to the proposition that radio waves can somehow be generated so as to provide an 'electromagnetic drive' to a spacecraft, but it unfortunately won't work. Electromagnetic waves won't drive a spacecraft anywhere. The E/M propulsion proponents claim that this isn't true, that The Government or the Illuminati or someone have perfected the technology and is concealing it from the world so that they can attain world domination or some damn fool thing.

Electrocutions for capital punishment in the United States are typically performed at voltages around 3,000 volts. The current is limited only by the resistance of the prisoner since a low-impedance transformer is used as a source. Electrodes are affixed to the head and one leg, salt water being used to maintain low resistance to the skin. Unconsciousness is instantaneous and death follows immediately afterwards. Despite the gory details that one sometimes hears about, the process is quiet, instantaneous, and presumably painless.

Stun guns, ignition systems, and static electric generators produce voltages in excess of 10kV, but the power supplies of these devices have an extremely high internal resistance. Consider a 100kV source that contains an inherent one million ohm resistance in series with that source. Now connect a 500 ohm resistance across the leads of this source and calculate the voltage across the 500 ohm resistance. This low voltage is what you'll get across a human body. That million ohm resistance protects you, and it's why you don't die when you get a static shock from a rug on a dry day.

ejazabidi,

Such a circuit would involve a great deal of circuitry. A tuner for your
computer would be better. The circuit, even if it existed, would probably
cost more than a TV set.

When the amount of current through a wire changes, one radio wave is produced. If undisturbed by reflections, this wave propagates in a sphere, moving out from the wire that produced it at the speed of light. Periodic changes in the current through a wire will produce a train of waves. The frequency, phase, and amplitude of the waves in this train can be changed in order to send information on the wave train.

The wave itself results from the change in the magnetic field around the wire. As you'll recall, a change in magnetic field across a conductor results in a voltage across that conductor: this is how a generator works. The same thing happens in the free space that surrounds the varying magnetic field; i.e., a changing magnetic field results in a changing electric field in the same region.

Now, we also know from our work with electromagnets that an electric field will drive current through a conductor and make it into an electromagnet. The same thing happens in the free space in which an electric field exists and is changing. Ergo, a changing electric field results in a changing magnetic field in the same region.

Now look at those last two paragraphs. We've got a changing magnetic field-->changing electric field-->changing magnetic field. And of course it goes on and on, repeating forever.

The important thing about this sequence of changing fields is the region of space where the magnetic and electric fields are changing. Everything we've said would indicate that the region of space that's near the wire with the varying current will contain the varying electric and magnetic fields. This is true, but there's more: the disturbance *propagates out from the wire*. A changing magnetic field generates a changing electric field a short distance out from the wire, and this generates a changing magnetic field some distance out further. This disturbance is the radio wave, and it travels at the speed of light. That's because it _is_ light, or the equivalent: light and radio and x-rays are all electromagnetic waves.

Electromagnetic waves go through a vacuum for the same reason that a magnet or a static electric field works in a vacuum: the fields don't need a medium in which to operate.

The easiest way to convince yourself that radio waves work is to tune an AM radio into a blank spot on the dial around 700kHz. Then start fooling with electrical stuff nearby. Flip the lights on and off, and you'll hear the signal in the radio. Or connect an inductor, a battery, and a couple of wires in series. Touch the wires together to make sparks, and listen to the radio crackle. With this arrangement, you could send digital code. If you worked quickly enough, you could send a list of numbers that would describe a picture or a sound waveform. This could be decoded by the receiver circuitry (one sort of computer or another) and the sound or picture reproduced accurately.

That's how it works.

Curtis,

A guy that EXPLORED and REVERSE ENGINEERED things like
BIOS code ... and "how a .exe executable really worked".

Exactly.

Somewhere along the way, "hacker" got a bad (very bad)
connotation. And it irks me, when people ... and the
news media (etc, etc) keep on reinforcing that stereotype.

When I was young the only people could pick on were teen agers.
When teen ager did something bad, like 'parking' or mischief,
people got to use the term as though that's all they did.
What if someone saw an auto mechanic trashing a car engine
and someone asked who that was and the reply was, that's
a mechanic. It's a stretch but if mechanics were a bit mysterious
to the general public word could get out, Don't let a mechanic
near your car, they trash engines. That's they way it happens
I think. Just like ham radio operators used to get people angry
at them when they caused radio or TV interference. The people
didn't know about the other things hams did. And of course in
that case the interference was usually not intentional. In fact
most good hams worked hard to avoid causing interference and
usually helped to solve the proem when they did cause any.
Misunderstandings abound, mostly due to less than the whole
story. We can't blame the media people though, they get
their information from whoever is said to know and if that
person is a victim he will probably make it seem that damage
is all hackers know how to do.

Guys,

I just couldn't keep quiet about this one ....

I've been doin' electronics since I was 'bout 9 or 10
years old. And I remember that when the term "hacker"
first popped up ... what it kinda meant was like "a
computer nerd" or "geek". A guy that really dug into
computers. MORE than the average guy....

A guy that EXPLORED and REVERSE ENGINEERED things like

A guy who wanted to learn it ... inside and out.

A real hobbyist.

J. Pinkston,

about hackers not giving up there secrets isn't necessarily true.

As I say, Never say Never! :-)

I have never had much sympathy for anyone who intentionally caused others wasted
time or money or butted into their business. Hackers, the bad ones, do that. A
hacker, I repeat is a lover of machines, sometimes computers. Some of them have
too much time on their hands and not enough respect for others, so the hack into
computers. Maybe the 'nerd' label applies and the just got teased too much when
they were young and they therefore lost respect for others who did not respect
them.
