how do we know that Leonardo Da Vinci came up with ideas of the helicopter and parachute?

Answer 1

he has detailed drawings of them - apparently the helicopter would not have worked. His hang-glider would work . . .not sure about the parachute.

Answer 2

I have studied Renaissance Art including the work of Leonardo da VInci for a long time now and I've been lucky enough to handle many of his original drawings.

I hate to say this but unfortunately Leonardo did not invent the helicopter. The helicopter-like drawing in Paris Manuscript B is actually a helix screw/device.

You have to be really careful with these so called inventions as people tend to see what they want to, not what was actually intended.

The knowledge that we have with regard to Leonardo da Vinci's inventions and art etc has been carefully accumulated over many years by academics who have been fortunate enough to examine the primary source evidence that is available with regard to him. They have translated thousands of documents, viewed art works and pieced together evidence from countless sources to give us the picture of Leonardo that we have today.

Answer 3

Because the details are in his notebooks and, although he may not have been the first to discover the principles, he was the first to write it down in a form that might have been useful as a military weapon.

I am quite sure he got his idea for the helicopter from watching sycamore or ash seeds falling and, perhaps, his idea for a parachute from thistledown.

Answer 4

We have his notebooks and sketches as a reference point to base our analysis on. If he had copied the ideas from someone, who could that have been? These ideas were far out of the 15th century when he lived. His knowledge was not limited to the immediacy of the century he lived in. The term genius is misused in our time, but he was the Renaissance Man, well ahead of his contemporaries in both knowledge, understanding and vision of things to come.

Answer 5

We don't know for certain who came up with those ideas first but Leonardo's drawings are the first known evidence so he gets the the credit.

Answer 6

We know that he made detailed sketches of them in his notebooks, but that also doesn't mean that he came up with the ideas. Someone else could have come up with the idea, and he developed it, or he copied the whole thing, or maybe it actually his, and only his, idea when he put it in his notebooks.

Answer 7

he wrote his ideas in notebooks that have become known as a "codex". in these notebooks are drawings that that can be looked at with the modern eye as being a helicopter or parachute.

Answer 8

We don't. It is a presumption based on their description in his marvelous notebooks. If the neighborhood bumpkin came up with the ideas, he, she, forsoothe left no record. Thus Leo gets the credit.

Answer 9

The plans and drawings for them are in his notebooks and papers. You can see copies in several books and online.

Answer 10

There are sketches of his inventions made by him that are still in existence today.
