Discussion Overview

The discussion centers around the historical context and implications of Luigi Galvani's observations in 1771, where he noted the movement of a dead frog's leg when stimulated by metal probes, which he termed "animal electricity." Participants explore the reasoning behind Galvani's connection of this phenomenon to electricity, as well as the broader scientific landscape of the time.

Discussion Character

  • Historical
  • Exploratory
  • Debate/contested

Main Points Raised

  • Some participants question why Galvani believed the frog's leg movement was related to electricity, seeking deeper insights into his reasoning.
  • Others suggest that there may have been contemporary experiments with electricity that influenced Galvani's conclusions.
  • One participant notes the subsequent work of Alessandro Volta, who expanded on Galvani's findings by experimenting with various metals and fluids, leading to the invention of the Voltaic pile.
  • There are discussions about the applications of "animal electricity" in modern technology, such as defibrillators and heart pacemakers.
  • Some participants express frustration over unanswered questions directed at the original poster, suggesting that they should conduct their own research before seeking answers from others.
  • There is a call for participants to engage with existing literature and ask specific questions based on their readings, emphasizing a self-directed learning approach.

Areas of Agreement / Disagreement

The discussion reflects a lack of consensus, with participants expressing differing views on the necessity of answering questions directly versus encouraging independent research. Additionally, the reasoning behind Galvani's conclusions remains a topic of exploration without definitive agreement.

Contextual Notes

Participants reference the historical context of Galvani's work and the scientific environment of the 18th century, but there are limitations in the discussion regarding specific experiments or literature that may have influenced Galvani's thinking.

I have read that in 1771 physician Luigi Galvani notices that the leg of a dead frog moves when being explored by metal probes. Galvani called this “animal electricity.”

Why does he think that this movement has anything to do with electricity?

Why do YOU think he does? Do you think he was wrong?

Further to @phinds question, what was going on in the literature at that time? Probably some experiments with electricity?... :smile:
 
There's a very interesting history associated with that discovery. After being made aware of the discovery Volta started experimenting with different metals and fluids other than those found in frogs and came up with the first practical batteries known as Voltaic piles.
Defibrillators and heart pacemakers are just two things where so called "animal electricity" is used.

Since the OP has not answered my question or @berkeman's why don't we let him do some research on his own before spoon feeding him stuff ?

@genefalk you have been asked questions in two different posts in this thread and I see you have visited the forum since then. It is bad form to avoid questions so how about answers?

Thank you for your kind words. Also, your question was kind of a non-question as it was reposing my question to me. I would not be asking if I knew the answer.

We do not spoonfeed people here. We expect them to do some reading and research on their own first, and ask questions here when the information at encyclopedia type sites (like wikipedia, hyperphysics, etc.) is not clear to them.

Please do some reading and post links to that reading. And ask specific questions about that reading if you are having trouble understanding it. That's the way the PF works, and it works very well. We try to help folks learn how to learn here... :smile:
