How It Works is the action-packed magazine that's bursting with exciting information about the latest advances in science and technology, featuring everything you need to know about how the world around you — and the universe — works.
The barometer invented by Hooke was the wheel barometer, which was used to measure the air's atmospheric pressure.
This barometer consisted of a curved tube, filled with mercury, and a ball that floated on top. The floating ball was attached to a pointer.
The tube, filled with mercury, sat upside down on a small container of mercury. When the air pressure increased, the increased weight pushing down on the mercury forced more mercury into the tube and caused the ball to move upward. This changed the measurement selected by the pointer, according to ThoughtCo. Hooke went on to develop his own versions of wind and rain gauges.
His tipping-bucket rain gauge emptied itself when filled with rain. The number of times the bucket became unbalanced and tipped was recorded to measure the cumulative volume of rainwater over a given time. Hooke's wind gauge was a reinvention of the original; as the wind speed changed, so did the position of an attached mobile panel.
To improve the thermometer, Hooke added further measurements, including the freezing point of water, according to Royal Society Publishing. Hooke's most famous work was his discovery of the living cell. Though scientists had invented the microscope decades earlier, Hooke's innovation dramatically improved the technology.
Hooke was very good at drawing, and when he was young his father thought he might become an artist. Hooke wrote a detailed personal diary between March and May When Hooke discovered a honeycomb-like structure in a slice of cork using his microscope he only saw cell walls because the cork was dead tree tissue and he coined the term "cell" for individual compartments he saw. Hooke attends Westminster School in London. Hooke starts working for the scientist Robert Boyle. Hooke invents the balance spring.
Hooke becomes Curator of Experiments at the Royal Society. Hooke becomes a fellow of the Royal Society. Micrographia is published. Hooke becomes Surveyor of the City of London. Lectures of Spring is published.

As an architect, Hooke designed many of the new buildings to be built after the Great Fire of London in , although his grid plan for the overall rebuilding of the city was rejected.
Hooke was appointed curator of experiments for the newly formed Royal Society of London in , a position he obtained with Boyle's support.
Hooke became a fellow of the society in Unlike many of the gentleman scientists he interacted with, Hooke required an income. In , he accepted a position as professor of geometry at Gresham College in London. After the "Great Fire" destroyed much of London in , Hooke became a city surveyor.
A true polymath, the topics Hooke covered during his career include comets, the motion of light, the rotation of Jupiter, gravity, human memory and the properties of air.
In all of his studies and demonstrations, he adhered to the scientific method of experimentation and observation. Hooke also utilized the most up-to-date instruments in his many projects. In this groundbreaking study, he coined the term "cell" while discussing the structure of cork.
He also described flies, feathers and snowflakes, and correctly identified fossils as remnants of once-living things. When paying a visit to this extraordinary building, please spare a thought for the genius who put it there: Robert Hooke.
