Thank you for the great video.
On an historical note, I don't agree on the fact that Galvani invented the battery.
Galvani setup an experiment that involved the use of a battery, where two different metals were the cathode and anode respectively, and the electrolyte was constituted by the bodily fluids of the dead muscle.
Galvani's explanation including animal electricity was totally incorrect. Alessandro Volta grasped the true chemistry going on there, and build the battery without the dead animal parts.
Galvani may have incidentally built a functional battery, but he wasn't aware of it.
Current history attributes the invention of the battery to Volta, with reason; it is an attribution with which I concur. I did a search following your video - at the University of Pavia with which Volta was associated - but things are standing the way they always had: Volta is still the inventor of the battery.
Regards,
Anthony

What I'd like to know is, when will modern science come up with a battery that lasts longer than what we've got now?
Electric cars and motorcycles all have extremely limited range entirely due to their inferior batteries. This alone is what's keeping electric vehicles from being practical and mainstream.
Everything about transportation has evolved except the battery. The most innovative thing that's happened to automotive batteries in the last quarter-century is simply going from a wet battery to a sealed battery. And it's still disappointingly weak and frustratingly short-lived.

We may measure batteries in volts, but we do it with a galvanometer. In your face, Volta!
Were you deliberately quoting from Frankenstein with that spark of life line? Some of the movie versions of Frankenstein are pretty good about giving the historic background. There had been preliminary successes in resuscitation, and it appeared by the science of the time that we were much closer than we turned out to be at achieving reanimation, artificial life, or some other major breakthru at understanding the nature of life.

Agree, so many great examples of 'accidental' discovery in this series. I was wondering Kathy, do you think it was the frog or the scalpel that got accidentally charged up by the nearby electricity machine? Must it have been the frog, because the scalpel being a conducter would have discharged as soon as it was picked up? Also evokes a nice image of a 1700's science lab: anatomy and electricity going on the same bench etc. :)

How did the frog legs kick when they were hanging from the fence, when there were clear skies? I saw that the leg was hanging by its nerve, from a copper hook, but there was still no circuit formed. Or was there actually another wire attaching the end of the leg to the fence, closing the circuit?

I'm just a regular Asian geek trying and Gilvani isbone of my idols in the field of science and med.
Huhuhu i hope my life won't be waste i am doing everything I can to contribute to science and write my name in history

Thanks for this video! I am an English teacher and I am going to use your video instead of an article to have my students compare Galvani's science experiments to experiments in a novel we are reading.

I'm doing Physics college and the goal of the one of the subjects is to make a Physics class with Science History. Your video has helped me a lot! Thank you! Very nice way to learn Science: )

You didnt mention it in your video so you inspired me to look up galvanic corrosion.
And now I have a perfect understanding of why I had to redo portion of the plumbing in my house.

Loved it. This video shows how complex science is, and how human emotions get involved in it. I am just sorry for all the frogs used to find out the secrets of electricity.

Just a little note: Alessandro Volta, not Alessandra. Alessandra is the female for Alessandro (male.
I'm enjoying a lot your videos! Thanks for sharing your researches!

Very specific point, but I would not say Galvani's frog was an invention, but a discovery. He discovered the effect of different metals with an electrolyte between them.

Please get rid of the background music. It's of no value to anyone and marks you as an ametuer presenter. You are spoiling your otherwise wonderful videos.

Hi Kathy, great video! Looks like you are doing great with your tags. Got to be frustrating to have so many views but not a lot of Subs. I subed.

That was a time when amphibians like frogs and the like were plentiful, before the species decline due to pesticides and loss of habitat.

Just a film tip, make sure the top of your head is at the top of the frame. This is called headroom. Trust me im a FILMAKER.

Now I want to read Frankenstein. It's Frawnkensteen! What a morbid series of experiments. Absolutely fascinating, though.
