Now, this is very interesting. Newton ascribed the discovery of the third law to his contemporaries in the Royal Society. He wasn't aware anyone had realized it or voiced it before them. That being the case, it is intriguing to see Leonardo had written it down as far back as the Renaissance. I am now curious to know if there's any record of it before Leonardo anywhere.
The very first thing that came to mind upon seeing this was Zeno's paradox. I wonder what sort of person this makes me...berkeman said:
Leonardo's Perpetual Motion Machine is a hypothetical device designed to continuously generate motion or energy without the need for an external source of power. It was first proposed by the Italian artist and inventor Leonardo da Vinci in the 15th century.
No, Leonardo's Perpetual Motion Machine was never built or proven to work. It remains a theoretical concept and has not been successfully created or demonstrated.
Leonardo was inspired by the idea of creating a machine that could run indefinitely without the need for human intervention. He was also influenced by ancient Greek and Roman designs of perpetual motion machines.
One of the main challenges was overcoming the laws of thermodynamics, which state that energy cannot be created or destroyed, only transferred. Leonardo's designs also faced practical challenges such as friction and wear and tear.
Leonardo's Perpetual Motion Machine is still studied today because it represents an important part of scientific history and the quest for perpetual motion. It also serves as a reminder of the limitations of human knowledge and the importance of experimentation and innovation in scientific advancements.
