Da Vinci Bridge Built

Re:It's not "da Vinci"; it's "Leonardo".

"da Vinci" is the last name. He's known as Leonardo because he signed as Leonardo

Not quite. Remember that Leonardo was born in 1452, well before modern European naming conventions developed. His full name of 'Leonardo di ser Piero da Vinci' means "Leonardo, sired by Piero, from Vinci".

So whilst "da Vinci" is the last chunk of his name, referring to this bridge as the work of "da Vinci" effectively means attributing it to "some bloke from Vinci". If he'd been born 400 years later, "da Vinci" would have been reasonably described as a surname, as it is, it stands as a reasonably useful way of referring to the man, but then so does 'Leonardo', which, as Kazzuya points out, has the benefit of being how the artist himself signed his work (let's not get into the 350 different ways Wm Sheakspeer spelled his name...)

...of this really cool game where you build bridges. It's in full 3D with a complex physics engine. I had a lot of fun with this game yesterday :)

Re:Leonardo's methods are the way forward

I don't think that's a fair way of looking at it. Geniuses come and go at random, but I don't think they're created by the education system or can be forced into a pigeonhole so easily. Its up to the individual to find their own direction. Take Richard Feynman, for example, a nobel prize winning theoretical physicist who helped build the atomic bomb, invented the concept of the quantum computer, figured out why the Challenger blew up, and even composed a bongo drum ballet. My old research advisor, Herb Simon, was a nobel prize winner in economics and also won a Turing Award for his hand in a substantial chunk of the beginnings of Artificial Intelligence.

On the other hand, if we used our education system to encourage everyone to do everything, I think we'd have a lot of non-genius folks who would just suck at lots of things. We're probably better off just letting the geniuses figure out that they're destined for bigger & better things.

I have a mirror for the pictures

I made a comment yesterday about mirroring a very large file and I would like to reinterate it here with some extra stuff.

I was able to get the pictures off the website and I have put them in a .zip file and I am sharing them on WinMX. I also included this note along with the pictures.

These files are probably copyrighted, I have made them avaible through other means in order to allow people who can not access the above web site due to the 'Slashdot Effect'. The files will be removed from my server 48 houres after the posting date of the artical above. Please do the same.

Find it by searching for: [SLASHDOT When I'm at my computer I will try to give this file 1st priority. It's hard (for me) to tell if a site will be /.'ed and if the pictures won't be avaible to others. I'm wondering what the rest of you think. It would be nice for the first posters to follow my example for sites that could go down quickly. How many of you would be willing to take some time to do the same? I think I have a nice template for setting up mirrors, (suggestions welcome).

Leonardo...

I see a few nay-sayers here, regarding the size and the materials used for this construction of da Vinci's bridge. It was originally meant to be of stone, and much bigger. Naysayers discuss that it is made of wood, and the inverse square law of size vs strength.

Now, I am not an engineer - and the arguments made are valid. But I do know a bit about Da Vinci - and the one thing he wasn't is incompetent.

If it was to be made of wood - he would have designed it that way - he knew about composite construction, from designing and building large (and not so large) torsion and bow-based siege engines for various sponsors. Many of his designs were meant to be done in wood, actually - others in stone, and still other in a combinations, which included metals and glass (optics, in that case).

He not only designed, but built large scale machines for boring long lengths of both wood and metal (for water pipes and cannons, respectively). These are large scale constructions and projects - I have no doubt that his full scale construction, as intended in stone, could be realized as he planned.

It is true that he saw farther than most men, and did lapse in areas that were more conjecture than real things that could work (his helicopter and ornithopter designs would likely not work - but they saw far, at the least - his parachute would have been fragile, and wouldn't have worked too well - but it has been built and tested - and it did work better than thought). But most of works are truely the "stuff of legends".

Here we are - 500 years after this man's death - still discussing, still trying out his ideas, ideals, and plans. I think of the sketched self-portrait of his as an old-man - as well as various other images I have seen of him. A powerful, muscular individual. This was a man intent on improving his mind, his body, and the world around him. It has been said that he was strong enough to bend an iron horseshoe with his bare hands - yet gentle enough to not harm an insect. He was supposedly a vegetarian. I have also heard he may have been homosexual.

None of this changes my image of the man - this man is a man to aspire to be like. A true individual who walked on the earth - and made it a better place through art, science, compassion, and dignity.

Re:No, its just a scale replica - with bandaids on

Notice in the picture the four T shaped supports holding up the spans outside the bows. Even with these supports the near span is visibly sagging. In DaVinci's design that area was to be filled with masonry, I hope they do something other than leave those inappropriate supports in place.

If you look at the model, you can see that the sag is part of the design. I'd be interested to know how this would have been done with stone, and without rebar :).
