The concept of precision agriculture first emerged in the United States in the early 1980s.

Henry Maudslay: Founder of precision engineering and first production line.

He must have felt, even if dimly, that if science interested him, it was not because he was first and last a lover of her laws and generalizations, nor only because the clarity and precision of science was congenial, but because science answered the questions of practical men and conferred knowledge and power upon those who would perform the labors of their generation.

The first full-specification PAL receivers (" PAL-D ") relied on a precision ultrasonic glass delay line, which in the early days was estimated would make up about a third of the cost of the receiver.

" When Smeaton saw the first engine he reported to the Society of Engineers that ' neither the tools nor the workmen existed who could manufacture such a complex machine with sufficient precision ' "

The second, precision ( al-ḍabṭ ), is of two types, the first is pertaining to memorization and the second to writing.

In 1981, the Space Shuttle made its first orbital flight, proving that a large rocket ship can take off into space, provide a pressurised life support system for several days, reenter the atmosphere at orbital speed, precision glide to a runway and land like a plane.

These theoretical relationships are more clearly illustrated in Fig. 7 and their sum can be seen to correlate in form with practical measurements made with the Hesiometer as illustrated in the first portion of Fig. 5 for the cutting mechanism.

On her first visit the orthodontist will take x-rays, photographs, tooth measurements, and `` tooth prints '' -- an impression of the mouth that permits him to study her teeth and jaws.

The first results from this mission, disclosed in 2003, were detailed measurements of the angular power spectrum to below degree scales, tightly constraining various cosmological parameters.

After Zwicky's initial observations, the first indication that the mass to light ratio was anything other than unity came from measurements made by Horace Babcock.

Ole Christensen Rømer (; 25 September 1644, Århus – 19 September 1710, Copenhagen ) was a Danish astronomer who in 1676 made the first quantitative measurements of the speed of light.

Cassini had observed the moons of Jupiter between 1666 and 1668, and discovered discrepancies in his measurements that, at first, he attributed to light having a finite speed.

The concept of p was first introduced by Danish chemist Søren Peder Lauritz Sørensen at the Carlsberg Laboratory in 1909 and revised to the modern pH in 1924 to accommodate definitions and measurements in terms of electrochemical cells.

Edmond Halley published the first measurements of the proper motion of a pair of nearby " fixed " stars, demonstrating that they had changed positions from the time of the ancient Greek astronomers Ptolemy and Hipparchus.

In 1921 Albert A. Michelson made the first measurements of a stellar diameter using an interferometer on the Hooker telescope.

The first measurements of the number of solar neutrinos reaching the earth were taken in the 1960s, and all experiments prior to SNO observed a third to a half fewer neutrinos than were predicted by the Standard Solar Model.

It was one of the first stars whose distance was estimated through parallax measurements.

* December – Ole Rømer makes the first quantitative measurements of the speed of light.

In the first several decades of the 20th century, other inventors attempted ( unsuccessfully ) to use gyroscopes as the basis for early black box navigational systems by creating a stable platform from which accurate acceleration measurements could be performed ( in order to bypass the need for star sightings to calculate position ).

The synchrotron radiation, which comes up as a side effect, was first used in 1967 for absorption measurements.

Ezekiel's ell, by which he gave measurements in his guided vision through a future Jerusalem Temple, is thus one sixth larger than the standard ell, for which an explanation seems to be suggested by the Book of Chronicles ; the Chronicler writes that Solomon's Temple was built according to " cubits following the first measure ", suggesting that over the course of time the original ell was supplanted by a smaller one.

In 2012, the first direct measurements of the strength of the van der Waals force for a single organic molecule bound to a metal surface was made via atomic force microscopy and corroborated with density functional calculations.
