Another da Vinci discovery

A historian doing a detailed study of Leonardo da Vinci’s research on the nature of friction has discovered his first notes on the subject, where da Vinci outlined the laws of friction two hundred years before they were finally documented by a French scientist.

“The sketches and text show Leonardo understood the fundamentals of friction in 1493,” says Hutchings. “He knew that the force of friction acting between two sliding surfaces is proportional to the load pressing the surfaces together and that friction is independent of the apparent area of contact between the two surfaces. These are the ‘laws of friction’ that we nowadays usually credit to a French scientist, Guillaume Amontons, working 200 years later.”

It is an unfortunate thing that da Vinci lived and worked in Italy. Though this was where the Renaissance blossomed, it is also the place where some scientists at the time were persecuted for being too honest about their research. To protect himself da Vinci confined his scientific genius to his private diaries, written in a backwards script he created so that no one could easily understand what he wrote. Thus, while his brilliance as a painter was recognized in his lifetime and after, the discoveries he had made about engineering and science were lost for literally centuries.

I wonder if there are individuals, especially in the climate field, who are now experimenting with similar techniques to hide their work.

Conscious Choice cover

Now available in hardback and paperback as well as ebook!

 

From the press release: In this ground-breaking new history of early America, historian Robert Zimmerman not only exposes the lie behind The New York Times 1619 Project that falsely claims slavery is central to the history of the United States, he also provides profound lessons about the nature of human societies, lessons important for Americans today as well as for all future settlers on Mars and elsewhere in space.

 
Conscious Choice: The origins of slavery in America and why it matters today and for our future in outer space, is a riveting page-turning story that documents how slavery slowly became pervasive in the southern British colonies of North America, colonies founded by a people and culture that not only did not allow slavery but in every way were hostile to the practice.  
Conscious Choice does more however. In telling the tragic history of the Virginia colony and the rise of slavery there, Zimmerman lays out the proper path for creating healthy societies in places like the Moon and Mars.

 

“Zimmerman’s ground-breaking history provides every future generation the basic framework for establishing new societies on other worlds. We would be wise to heed what he says.” —Robert Zubrin, founder of founder of the Mars Society.

 

All editions are available at Amazon, Barnes & Noble, and all book vendors, with the ebook priced at $5.99 before discount. The ebook can also be purchased direct from my ebook publisher, ebookit, in which case you don't support the big tech companies and I get a bigger cut much sooner.

 

Autographed printed copies are also available at discount directly from me (hardback $24.95; paperback $14.95; Shipping cost for either: $5.00). Just email me at zimmerman @ nasw dot org.

    Could you imagine what Devinci would have done with some technology, this man was way beyond his time, the early contraptions with say a internal combustion engine most likely could have flown.

    Indeed. Archimedes, Hero of Alexandria and Leonardo are the three leading “just missed it” men who might have, had things gone a bit differently, initiated an Industrial Revolution centuries or even millenia before it actually happened in 18th century England. Particularly with respect to the two Greeks, just imagine where we’d probably be now if steam power had debuted in the 3rd century B.C.

  • “I wonder if there are individuals, especially in the climate field, who are now experimenting with similar techniques to hide their work.”

    Robert, that you would even consider such a notion says much about our country: none of it encouraging.

    Joe,
    da Vinci today would’ve been bogged down in some bugged code and bureaucracy and would never have gotten anywhere. He’d even study contemporary law to find out what is stopping him, and that is a confirmation of the end.
