Designed Shenfield Place, Brentwood for Lord Vaughan

Designed a house for Lord Burlington, probably Londesborough House.

Designed Ragley Hall for Lord Conway.   

Was considerably involved in the alterations to Westminster Abbey.   

Supervised the construction of more that 30 of Wren’s London Churches.

Invented a horizontal sail for windmills.   

Demonstrated the principle of the catenary curve and its potential application to architecture, notably  to the Dome of St. Paul’s.

Armaments

Invented an air gun

Atmosphere

Created five weather monitoring instruments

Constructed first Wheel Barometer

Invented the first instrument in England for measuring wind strength

Designed and built the air pump used by Robert Boyle to do experiments on the properties of air, and effects of reduced air pressure on humans.

Cells

First person to coin the word "cell" to describe the tiniest components of living systems - Plants.   

Was the first to observe and draw Polyzoans (microscopic animals in sea moss).

Clocks

Was instrumental in the design and improvements to clocks, especially those crafted by master clockmaker Thomas Tompion  

Invented the circular flywheel still used in many analogue watches today  

Designed and demonstrated to the Royal Society on 20th February 1668 a marine chronometer employing counter wound spiral springs and double balances as a possible solution to finding longitude.

Elasticity

Defined Hooke's Law which states :-  

“When a spring is fixed as one end and a force applied to the other the extension of the spring is proportional to the applied force, provided the elastic limit is not exceeded”

“The deformation of a material is proportional to the force applied”

Hooke illustrated the law by reference to four different experimental situations:-

  •  Loading a wire (deformation is increase in length)
  •  Loading a spiral spring (deformation is increase in length)
  •  Loading a horizontal beam (deformation is the depression of the free end)

 Tightening a watch spring (deformation is angular rotation)

He formulated the correct theory of elasticity, stating that an elastic body stretches in proportion to the force that acts upon it

Extinction

250 years before Darwin he realised the true nature of fossils. He realised they were dead creatures from pre-history and postulated that some had probably died out.   Realisation stemmed from his microscopic studies of fossils

Hearing

Invented an ear trumpet

Iris

Invented the Iris diaphragm

Jupiter

Discovered the red spot of Jupiter and first person to report the rotation of this planet

Keel

Developed the first false keel to improve the stability of ships. Today’s ships have stabilising fins based on this idea

Light

He supported the wave theory of light

Magnetism

Hypothesized that the magnetic poles of the earth were subject to change and reversal and were not fixed

Medicine  

Notionalised the first hypodermic needle from his microscope studies of nettles. He was the first to make an amalgam of mercury which was later used in dentistry.

Microdots

Formulated the first notion of using microdot blobs of ink for conveying messages secretly

Microscopy

Founded the field of Microscopic Biology through his Published work in 1665 "Micrographia"

Devised one of the best microscopes of his time - the worlds first compound microscope complete with his iris diaphragm and Sotoscope  illumination.   

Invented the iris diaphragm.  

Designed the first telescopic sight with cross hairs.   

Brownian Motion, he was the first to observe what was later to be rediscovered by Robert Brown.   

Constructed one of the first reflecting telescopes based on the ideas of James Gregory.

Planetary Motion

Formulated the theory of planetary motion as a problem in mechanics, and demonstrated, for the first time, the elliptical path of planets in their orbits around the sun

Pressure

First person in England to carry out experiments on the effects of reduced pressure on humans, using himself as the first guinea pig

Refraction

Created the refactometer to measure the index refraction of liquids

Respiratory

Constructed the first prototype of a respirator

Sash windows

Invented the balance weights used in sash windows

Shipbuilding

Developed the first false keel to improve the stability of ships.   Today's ships have stabilising fins based on this theory

Designed and constructed a way-wiser for the sea, an instrument, similar to an odometer, for measuring the distance traversed by a ship or the speed of water flow.

Solar System

Discovered the red spot of Jupiter and was the first person to report the rotation of this giant planet.  

Formulated the theory of Planetary motion as a problem in mechanics and demonstrated, for the first time, the elliptical paths of planets in their orbit around the sun.      

Was the first person to conceptualise the theory of gravity and its inverse square effect, from which Newton was able to learn from and develop the mathematics of gravity.   

Argued that the earth was an oblate spheroid with a gravity pull variant at different points of the globe.    

Designed the first equatorial quadrant.   

Was the first to observe and record the existence of sun spots.   He designed and built the first Helioscope for studying the sun.   

Uranus, he discovered a new planet on 22nd January 1673 100 years before it was rediscovered by William Herschel.  

Hypothesizes the initial fluid state of the earth.   

Discovered and proved that the comet seen in 1665 was the same one seen in 1618

First person in England to observe stars in daylight using a zenith telescope

Sound

Discovered that sound could travel along a wire and around corners.   

Determined that sound was the effect of a system of beats, measuring middle C to be 272 beets a second.

Synthetic fibres

Postulated on the possibility of synthetic silk through the spinning of threads of glutinous substances 200 years before they were made

Telegraphy

Invented a method of telegraphy based on telescopes and proportional signs in the 17th centuary

Underwater

Invented a diving bell.  

Invented a depth sounding machine.

Accomplishments

A large number of achievements have been attributed to Robert Hooke.   While most are correct, some are merely inventions to which he contributed developments , and others topics on which he worked.  The following is an alphabetical list of these attributions.
