The Horrendous Eyeball

(Newton Drawings, continued…)

This is a drawing Newton made of an experiment where he pressed his own eyeball with a “bodkin”–a kind of blunt needle–to see what colors appeared in his field of vision.

Don’t ask me for details, but somehow, he made himself do it because he so wanted to understand where colors came from and how they worked.

Once I got over the full strangeness and wonder of this drawing, the thing I also really like about it is the little hand.  I like how Newton draws hands.  Below are closeups of another page from one of his notebooks.

I don’t know of any surviving drawings where the strange, reclusive Newton showed more of his fellow humans than just a disembodied hand. But how I would love to see some!

Mysterious mechanical devices

(Newton drawings, continued…)

I first saw these in a concise and wonderful biography of Isaac Newton by James Gleick. I admit I’m not sure exactly what any of the gizmos actually do, but I still find them intriguing.

And while we are on the subject of gizmos, contraptions, etc…

As a boy,  Newton made a four-wheeled go-cart equipped with a rope, a cylinder, and a crank.  In a toy store, I saw the modern go-cart below and thought right away of Newton’s cart.

It’s said of Newton’s cart that when he sat in it and turned the crank, the cart would carry him all around the house.

The video below gives you the idea of how the modern one works. Note  she is riding on a flat surface, not downhill. It also works inside houses.

Perhaps both carts work on the same principle?

Newton’s snowflake drawings

I first saw these wonderful snowflake drawings by Isaac Newton, um, someplace on the internet. When I wanted to use them in my book Isaac the Alchemist, Secrets of Isaac Newton, Reveal’d, I  emailed all sorts of experts asking if they knew where in Newton’s many, notebooks the snowflakes might be found. No luck. So I sent a tweet to the Cambridge Digital Library (@CamDigLib), and within minutes got this link back.

Newton did all sorts of cool drawings. It would be great if there were a book of them so people could just page through and find them easily. On, sigh, actual paper.  But in the meantime, I will post a few more of my favorites.

(MANY thanks to the Cambridge University Digital Library for letting the public share these great images online.)




Where Isaac the Alchemist was born

“The house had a grand name, Woolsthorpe Manor, but none of the castle-like splendor the word manor calls to mind. Mice scurried down the halls and wooden staircases and across the cold stone floors.”

Isaac the Alchemist, Secrets of Isaac Newton, Reveal’d,  p. 3

Here (from Publishers Weekly) is the latest review!

In this charming biography of Isaac Newton (1642–1727), Losure (Wild Boy) posits that “this last sorcerer—this greatest of all alchemists—was the same man who banished magic from the scientific world.” Portrayed as an uncommonly inquisitive, albeit reclusive, thinker with a secret addiction to alchemy (not an unusual preoccupation in a period when the borders between science and magic were uncertain), Newton may have written as many as a million words regarding alchemy, papers he kept while destroying many related to his revolutionary work in other fields: mathematics, optics, and what is now called physics. Interspersing engrossing chapters about alchemy (but largely ignoring the last third of Newton’s life), Losure uses a light touch to trace his childhood endeavors, his rise from student to professor at Cambridge’s Trinity College, his prickly relationship with other scientists in the Royal Society (Newton became a member in 1672), and the publication of his masterpiece, Philosophiae Naturalis Principia Mathematica, in 1687. Period images and afterwords with curiosity-spiking headings such as “Stinks, Bangs & More Chymical Secrets” bring additional depth and interest to this study of Newton’s surprising pursuits. Ages 10–up. (Feb.)
