Simple books can be inspiring; specially those with nostalgic black and white engravings.
507 Mechanical Movements by Henry T. Brown is one of those books; now available in a special clean edition.
Curious about how complex pulleys with multi ropes work? What are worm gears? What are watches escapements? You can have short descriptions of those and hundreds more in Brown's compendium. Click here to learn about 507 Mechanical Movements
Is there a possibility that some of the Biblical passages be explained only with the aid of geometry? William A. Granville, the author of the controversial book The Fourth Dimension and The Bible thinks so.
Ancient writers were unable to interpret hyperspace events as we do today, so hidden in some Biblical books are some truths that only be revealed with the aid of modern physics and science. Learn more about this controversial book!
Mathematicians write about the fourth dimension in terms of formulas, abstract symbols, and hyperspaces.
Physicists write about the fourth dimension in terms of curved spaces and hidden dimensions.
But literature writers show more freedom in their expression of their ideas. A. T. Schofield goes to the extreme in his book: Another world, or the fourth dimension. He deeply examines The Bible to arrive at the conclusion the many of its passages make allusion to the fourth dimension. What are those mysterious tales? Learn about it in About how A. T. Schofield found the fourth dimension in the Bible.
The Story of Euclid is a fascinating book about ancient Greek mathematicians, specially the life of the great geometer Euclid. Almost every concept included in elementary textbooks in geometry was already developed by those mathematicians. This EBook is not about geometry exercises, nor about analytic geometry; this EBook is about the man who laid the foundations for this beautiful branch of mathematics and visual reasoning.
Can you recognize the figure at right? Will you bet that it is Leonardo Da Vinci's Mona Lisa? Why is it so distorted?
Well, believe it or not, you are seeing the Mona Lisa as if it were painted on the surface of a helicoid.
Transformations are a special and delicate subject in mathematics. Transformations are commonly used in the engineering fields of physics, heat-conduction, air-flow, etc. But transformations are also used in art where objects are seen from another standpoint of view. You can download an EBook full of transformations.

Can someone be found guilty of using a telescope? Can someone be found guilty of exploring new frontiers of science?
Well, not in this times, but this was not the case some 400 years ago. However, Galileo was confronted with both scenarios.
Being a brilliant man as he was, he may have had a double intention when he "arraigned personally" to the Inquisition. Galileo was an arrogant man, controversial, and contentious. Did he deliberately sign the abjuration document just to insert a Trojan horse to the Catholic Church?
This is also the title of one of the essays of The Vengeance of Galileo. But the EBook is full of other critical essays on science and the philosophy of science. What's the myth?
