History of Batteries & Electromagnetism (voltaic pile)

The Voltaic pile and the discovery of electromagnetism. These technologies lead us to electromagnetic communication systems...and a communications revolution. Featuring observations by Alessandro Volta & Hans Christian Oersted.

You just make it easy to rethink about all these simple principles. please keep this on .. these videos are very meaningful. :)

Good one!

[@mail4junkil]

Awesome!! Love you videos!

1.digitize (discretize) the message 2.compress it 3.send it at high frequency (more bit per given time) 3. ???? 4.Profit! If you only have analog system, then I guess it would make sense to use information dense language (or protocol), so the meaning can be conveyed in fewer words or deploy multiple antennas for different frequency, so you can send each message on each frequency (kind of like listening to multiple radios stations)

Is it possible to connect the negative of one battery to the positive of another battery and put an led in between the two batteries to power it. Because the negative ions of one battery will get attracted to the positive of the other battery right?.

Most letters per second VS most bits per second. Bits win big time haha now the challenge is the fastest bit transfer/storage per second. That's gonna involve quantum entanglement and that's the future of communication.

Agreed

great content, but the music is kind of off-putting

The explanation of batteries is misleading. You are correct in saying that zinc is giving up electrons, but solid copper is not taking electrons. There is no Cu-.
