He planned to take religious vows, but his parents persuaded him not to do so. Galvani attended the medicine course, which lasted four years, and was characterized by its "bookish" teaching.

Hers was a hyper-literate household attuned to the latest scientific quests, and her parents Godwin soon remarried hosted many intellectual visitors. One was a scientist and inventor named William Nicholson, who wrote extensively on chemistry and on the scientific method. Another was the polymath Erasmus Darwin, grandfather of Charles.

At just 16 years old, Mary ran off with poet and philosopher Percy Bysshe Shelley, who was married at the time. A Cambridge graduate, Percy was a keen amateur scientist who studied the properties of gases and the chemical make-up of food.

Empedocles of Acragas (c. BC) Inventor of rhetoric and borderline charlatan. His arbitrary explanation of reality with 4 elements (Earth, Air, Fire and Water) and 2 forces (Love and Strife) dominated Western thought for over two millenia. 3 Laying the Corner Stone: It is the best of times and it is the worst of times for chemistry. Lavoisier and the foundation of a modern science. Gypsum and “fixed water” anticipate the phenomenon of “fixed air.”. The frog galvanoscope, and other experiments with frogs played a part in the dispute between Galvani and Alessandro Volta over the nature of electricity. The instrument is extremely sensitive and continued to be used well into the nineteenth century, even after electromechanical meters came into use.

The genesis of Frankenstein can be traced back towhen the couple spent the summer at a country house on Lake Geneva, in Switzerland. Lord Byron, the famous poet, was in a villa nearby, accompanied by a young doctor friend, John Polidori.

The weather was miserable that summer. We now know the cause: InMount Tambora in Indonesia erupted, spewing dust and smoke into the air which then circulated around the world, blotting out the Sun for weeks on end, and triggering widespread crop failure; became known as the "year without a summer.

As storm after storm raged outside, Byron proposed that they each write a ghost story. Walton hopes to reach the North Pole a goal that no one would achieve in real life for almost another century where he might "discover the wondrous power that attracts the needle"—referring to the then-mysterious force of magnetism.

The magnetic compass was a vital tool for navigation, and it was understood that the Earth itself somehow functioned like a magnet; however, no one could say how and why compasses worked, and why the magnetic poles differed from the geographical poles.

Victor recounts to Walton that, as a student at the University of Ingolstadt which still existshe was drawn to chemistry, but one of his instructors, the worldly and affable Professor Waldman, encouraged him to leave no branch of science unexplored.

If your wish is to become really a man of science, and not merely a petty experimentalist, I should advise you to apply to every branch of natural philosophy, including mathematics.

Whence, I often asked myself, did the principle of life proceed? Davy also believed in the power of science to improve the human condition—a power that had only just been tapped. Victor Frankenstein echoes these sentiments: Scientists "have indeed performed miracles," he says.

They ascend into the heavens; they have discovered how the blood circulates, and the nature of the air we breathe. They have acquired new and almost unlimited Powers …" Victor pledges to probe even further, to discover new knowledge: Erasumus Darwin was a key figure in the study of spontaneous generation.

There, she claims that Darwin "preserved a piece of vermicelli in a glass case, till by some extraordinary means it began to move with a voluntary motion.

Victor pursues his quest for the spark of life with unrelenting zeal. First he "became acquainted with the science of anatomy: In Italy, inAllesandro Volta had developed the "electric pile," an early kind of battery.

A little earlier, in the s, his countryman Luigi Galvani claimed to have discovered a new form of electricity, based on his experiments with animals hence the term "galvanism" mentioned above.

This was long before people routinely donated their bodies to science, so deceased criminals were a prime source of research. So the idea that the dead might come back to life through some sort of electrical manipulation struck many people as plausible, or at least worthy of scientific investigation.

One more scientific figure deserves a mention: Like Volta and Galvani, Ritter worked with electricity and experimented with batteries; he also studied optics and deduced the existence of ultraviolet radiation. But just as Ritter was making a name for himself, something snapped.

He grew distant from his friends and family; his students left him. In the end he appears to have had a mental breakdown. In The Age of Wonderauthor Richard Holmes writes that this now-obscure German may have been the model for the passionate, obsessive Victor Frankenstein.

What is the correct or better way of energizing a 15/20 Mva, ONAN/ONAF, KV, DYn1 Power Transformer serving at . The name Galvanization is derived from Luigi Galvani, and was once used as the name for the administration of electric shocks (also termed in the 19th century Faradism, named after Michael Faraday), this stems from Galvani's induction of twitches in severed frog's legs, by his accidental generation of electricity.

Luigi Galvani was born on September 9, in Bologna, Italy. In his youth, Galvani intended to pursue a theology.

Largely due to parental influence, however, when he entered the University of Bologna it was to study medicine.
