Who is the Father of pneumatics?
Ctesibius
At the heart of our first episode is Ctesibius: The barber of Alexandria – the father of pneumatics. The scientist, who primarily studied the properties of air, and who is known by posterity as the father of pneumatics (from pneuma = air) lived and ‘operated’ during the early-3rd century BC.

When was Ctesibius water clock invented?
Greece (ca. 5th century BC ) Ctesibius is reputed to have constructed such a clock about 250 BC. He used another container to fill the container from which the water flows keeping its water level constant though a floater that opens a valve if the water falls below a level.
How did Ctesibius invent the alarm clock?
Ctesibius Made the Alarm Clock More Efficient He made modification to the standard water clock with a dial and pointer, which were designed to indicate a certain time. At the time indicated on the dial, pebbles would drop onto a gong, thus signaling the alarm.
Who invented water clock?
The oldest documentation of the water clock is the tomb inscription of the 16th century BC Egyptian court official Amenemhet, which identifies him as its inventor.
What did Ktesibios or Ctesibius of Alexandria discover and why is it noteworthy?
Ctesibius Of Alexandria, Ctesibius also spelled Ktesibios, (flourished c. Ctesibius was the son of a barber. The discovery of the elasticity of air is attributed to Ctesibius, as is the invention of several devices using compressed air, including force pumps and an air-powered catapult.
What was the first true experimental platform for artificial intelligence?
What was the first true experimental platform for Artificial Intelligence? Shakey, a robotic platform from Stanford University.
How did Ctesibius clock work?
Such a water clock dates back to the third century B.C. and was also attributed to Ctesibius. The constant flow of water into the clock would, by means of a float, slowly raise an indicator, a small figurine with a stick for example. The stick would point to the time as displayed on a column.
Who invented sundial?
The mathematician and astronomer Theodosius of Bithynia ( c. 160 BC to c. 100 BC) is said to have invented a universal sundial that could be used anywhere on Earth. The Romans adopted the Greek sundials, and the first record of a sundial in Rome is 293 BC according to Pliny.
Who first used an alarm clock?
Levi Hutchins
The first American alarm clock was created in 1787 by Levi Hutchins in Concord, New Hampshire. This device he made only for himself however, and it only rang at 4 AM, in order to wake him for his job. The French inventor Antoine Redier was the first to patent an adjustable mechanical alarm clock, in 1847.

How did Ctesibius contribute to the science of hydraulics?
This showed Ctesibius that the air is a body and led to the invention of the cylinder and the plunger. 7 He developed the science of pneumatics, now called hydraulics, probably in collaboration with Strato of Lampsacus, 8 who lived in Alexandria until about 288 B. C. Vitruvius praises Ctesibius theoretical introduction to the subject. 9
