how has scientific ideas on the use of electricity changed?

Answer 1

Hmmm. Science is constantly changing as new discoveries are made. The use of electricity was just a parlor trick a few hundred years ago, able only to twitch excised frog muscle when same was connected to a voltaic pile.

Early medical practitioners made all sorts of healing claims for the use of electricitiy, most of which have since been refuted. Then along came Edison to give us practical electrical lighting, and Tesla to give us a practical way to send electricity over long distances and operate efficient motors.

Do we still routinely shock people to "improve their health" or "test their strength?"

I remember a machine installed in a roller rink that, for a penny, would shock you when you grasped and turned its handle. Tesla set up apparatus to induce high-frequency currents in subjects, school children allegedly, without their knowledge in an attempt to improve their health.

Electro-shock treatment is still used to "treat" (mechanism unknown) mentally ill patients; it causes amnesia.

Some states still use electricity to "cook" the condemned until they are dead. The inventor of this concept touted it as more humane than hanging, which requires some skill to execute promptly. On a small scale, it's a great way to cook hotdogs.

All this stuff originated as a "scientific idea" in someone's mind, and then was either put to use or abandoned if it didn't prove useful. Except for quacks: they will continue selling electrical quackery as long as suckers will buy it.

Answer 2

i'm no longer out to disprove a dang element! What you prefer to incorporate or reject... is on you. no be counted what, you won't be in a position to pass lower back to the 1st something and say the way it got here approximately factually, that's what you're saying we can't do.... so.... once you place expectancies of Christians, use the comparable measuring usual on your self... because of the fact technically YOU and US are in the desirable comparable boat, different than for that, you in simple terms prefer to stick to technology as your God, greater or much less. version could properly be measured and shown. Many existence varieties have adapted to environment; there is not any question approximately that. yet so a techniques as guy is going.. the chromosomes of primates and "early guy" do no longer tournament as much as us.. why? because of the fact they're a distinctive species than us. till they hit upon a conclusive transitional fossil.. PROVING we developed from a primate... ( that isn't in any respect take place) i'm no longer determining to purchase it. i think of your declare that that's how humanity got here approximately is stupid without help, and on an identical time as a non Christian did no longer have self assurance it. Have an concepts-blowing day.

Answer 3

You could write an essay on this question - all the way from the first light bulb to quantum computers!
Discoveries along the way include X-rays, electromagnetic induction, vacuum tubes, wireless radio waves, solid state diodes, transistors, integrated circuits and we've only just begun.
