The interaction of physics and artillery begins with Galileo (there was no physics to talk about before that time except the statics). There are pictures in the books before Galileo which show completely unrealistic trajectories of projectiles. Galileo developed a computational device which he called the Geometric and Military Compass, which he produced and ...

The best answer to that question is the following book: The steam engine of Thomas Newcomen by L. T. C. Rolt, J. S. Allen 1977 Moorland Pub. Co. ; New York : Science History Publications, To summarize what I learned from this book. The boilers did not generate enough steam pressure to move pistons. You needed to use the weight of the atmosphere for the ...

Historians believe that the extant version of Problemata was not penned by Aristotle personally, but “while the Problemata is not the genuine Aristotelian work, it nevertheless contains an element derived from such a work”. Problemata XXXII.5 discusses breathing under water, including the oft quoted passage interpreted as referring to a diving bell:”Why do ...

The technology is that of the "Voder" and "Vocoder" exhibited at the 1939 World's Fair in New York City.

There is a recent pop technology history book How to Wreck a Nice Beach on the subject. The first non ...

There's a stop, or set of stops, on many cathedral organs called "vox humana." Granted these can only produce human-like vowel sounds, but that's the first "synth" I know of. Now, prior to modern "text to speech" digital software, there was a period in the 1970s and early 80s when a limited, hardwired, voice synth was available. See for example "Firepower"...

In physics, the four most important developments had nothing to with war or the preparation of war: Newtons calculus and his theory of gravitation, Maxwells equations, Einsteins theory of special and general relativity, Heisenbergs Matrix Mechanics in QM.

Not only war but preparations to war, military-related research had very large influence on the development of science and technology. Of the recent examples I mention GPS, Internet, space exploration, not even speaking of nuclear energy. GPS and satellite navigation in general were originally developed for military purposes, and most importantly the ...

Drones fly on the same principles as the ordinary airplanes or helicopters. So the main difficulty in developing of drones was the problem how to control them, not how to make them fly. And this problem of control has nothing to do with birds or insects. Actually airplanes have also little to do with birds and insects because they use different aerodynamic ...
