Niccolò Tartaglia publishes Nova Scientia, a treatise on gunnery science. This was Tartaglia's first published work and was described by Matteo Valleriani as: ... one of the most fundamental works on mechanics of the Renaissance, indeed, the first to transform aspects of practical knowledge accumulated by the early modern artillerists into a theoretical and mathematical framework. Then dominant Aristotelian physics preferred categories like "heavy" and "natural" and "violent" to describe motion, generally eschewing mathematical explanations. Tartaglia brought mathematical models to the fore. One of his findings was that the maximum range of a projectile was achieved by directing the cannon at a 45-degree angle to the horizon.

Pascal's calculator or the Pascaline constructed

The mezzotint printmaking method was invented by the German amateur artist Ludwig von Siegen. Mezzotint is a printmaking process of the intaglio family, technically a drypoint method. It was the first tonal method to be used, enabling half-tones to be produced without using line- or dot-based techniques like hatching, cross-hatching or stipple. Mezzotint achieves tonality by roughening the plate with thousands of little dots made by a metal tool with small teeth, called a "rocker." In printing, the tiny pits in the plate hold the ink when the face of the plate is wiped clean. A high level of quality and richness in the print can be achieved.

Gottfried Wilhelm von Leibniz invents the Staffelwalze (stepped drum, or stepped reckoner), the first mechanical calculator that could perform all four mathematical operations. Its intricate precision gearwork, however, was somewhat beyond the fabrication technology of the time; mechanical problems, in addition to a design flaw in the carry mechanism, prevented the machines from working reliably. Despite the mechanical flaws, it suggested possibilities to future calculator builders. The operating mechanism, invented by Leibniz, called the stepped cylinder or Leibniz wheel, was used in many calculating machines for 200 years, and into the 1970s with the Curta hand calculator. In discussing his invention, Leibniz wrote Indignum enim est excellentium virorum horas servii calculandi labore perire, qui Machina adhibita vilissimo cuique secure transcribi posset — For it is unworthy of distinguished men to waste their time with slavish calculations, which can be done safely with the use of this machine by anyone else.

Eli Whitney invents the cotton gin (cotton enGINe), a machine that quickly and easily separates cotton fibers from their seeds, allowing for much greater productivity than manual cotton separation. By reducing the labor of removing seeds, the cotton gin made cotton growing more profitable, thereby raising demand for slave labor. The first federal census of 1790 counted 697,897 slaves; by 1810, there were 1.2 million slaves, a 70 percent increase. Slavery spread from the seaboard to some of the new western territories and states as new cotton fields were planted, and by 1830 it thrived in more than half the continent. Within 10 years after the cotton gin was put into use, the value of the total United States crop leaped from $150,000 to more than $8 million.

Nicéphore Niépce abandons silver halide photography as hopelessly impermanent and tries using thin coatings of Bitumen of Judea on metal and glass. He creates the first fixed, permanent photograph, a copy of an engraving of Pope Pius VII, by contact printing in direct sunlight without a camera or lens. It is later destroyed; the earliest surviving example of his "heliographic process" is from 1825.

Physicist Michael Faraday (1791-1867) describes the liquification of chlorine in On fluid chlorine. Faraday finds that gasses of certain kinds, when kept under constant pressure, will condense until they cool. This latter discovery ushers in the beginning of mechanical methods of refrigeration.

Small-scale drilling for oil begins at Baku, a Russian port city on the west coast of the Caspian Sea, now the capital of Azerbaijan. The drilling marks the beginning of the modern petroleum industry, and by 1900 nearly half the world's oil will come from the Baku oil fields.

Nicéphore Niépce makes the first durable, light-fast camera photograph, similar to his surviving 1826-1827 photograph on pewter but created on the surface of a lithographic stone. It is destroyed in the course of subsequent experiments.

Louis-Jacques-Mand Daguerre perfects and presents the daguerreotype process as the first publicly available photographic process (which for nearly twenty years was also the one most commonly used). To make the image, a daguerreotypist would polish a sheet of silver-plated copper to a mirror finish, treat it with fumes that made its surface light sensitive, expose it in a camera for as long as was judged to be necessary, which could be as little as a few seconds for brightly sunlit subjects or much longer with less intense lighting; make the resulting latent image on it visible by fuming it with mercury vapor; remove its sensitivity to light by liquid chemical treatment, rinse and dry it, then seal the easily marred result behind glass in a protective enclosure.

Henry Fox Talbot publicly introduces the paper-based process he worked out in 1835, calling it "photogenic drawing", but it requires much longer exposures than the daguerreotype and the results are not as clear and detailed.

John Herschel introduces hyposulfite of soda (now known as sodium thiosulfate but still nicknamed "hypo") as a highly effective fixer for all silver-based processes. He also makes the first glass negative.

Sarah Anne Bright creates a series of photograms, six of which are known to still exist. These are the earliest surviving photographic images created by a woman.

The first tunnel under the Thames opens on March 25, built by Isambard Kingdom Brunel (1806-1859). {a]The Thames Tunnel{/a} connects Rotherhithe and Wapping, London. Although it was a triumph of civil engineering, the Thames Tunnel was not a financial success. It had cost a fortune to build — £454,000 to dig and another £180,000 to fit out — far exceeding its initial cost estimates. Proposals to extend the entrance to accommodate wheeled vehicles failed owing to cost, and it was only used by pedestrians. It became a major tourist attraction, attracting about two million people a year, each paying a penny to pass through.

In Hartford, Connecticut, dentist Horace Wells (1815-1848) uses nitrous oxide as an anesthetic; he is the first to do so.

Arithmometer: first commercially successful mechanical calculator launched

The fast-acting Collodion process invented by Frederick Scott Archer. Images require only two or three seconds of light exposure. Collodion process, mostly synonymous with the "collodion wet plate process", requires the photographic material to be coated, sensitized, exposed and developed within the span of about fifteen minutes, necessitating a portable darkroom for use in the field. Collodion is normally used in its wet form, but can also be used in humid ("preserved") or dry form, at the cost of greatly increased exposure time. The latter made the dry form unsuitable for the usual portraiture work of most professional photographers of the 19th century. The use of the dry form was therefore mostly confined to landscape photography and other special applications where minutes-long exposure times were tolerable.

Isaac Singer patents the continuous-stitch sewing machine.

The Erie Railroad, now controlled by Daniel Drew, becomes the first rail line connecting the Great Lakes with New York City, and begins to compete with the Erie Canal as a transportation route.

André-Adolphe-Eugène Disdéri credited with introduction of the carte de visite (English: visiting card or calling card) format for portraiture. Disdéri uses a camera with multiple lenses that can photograph eight different poses on one large negative. After printing on albumen paper, the images are cut apart and glued to calling-card-size mounts. Photographs had previously served as calling cards, but Disdéri's invention of the paper carte de visite (i.e. "visiting card") enabled the mass production of photographs. On 27 November 1854 he patented the system of printing ten photographs on a single sheet (although there is no evidence that a system printing more than eight actually materialized). Disdéri's's cartes de visite were 6×9 cm, about the size of conventional (nonphotographic) visiting cards of the time, and were made by a camera with four lenses and a sliding plate holder; a design inspired by the stereoscopic cameras. The novelty quickly spread throughout the world. According to a German visitor, Disdéri's studio became "really the Temple of Photography - a place unique in its luxury and elegance. Daily he sells three to four thousand francs worth of portraits". The fact that these photos could be reproduced inexpensively and in great quantity brought about the decline of the daguerreotype and ushered in a carte de visite craze as they became enormously popular throughout Europe and the United States. Disdéri also invented the twin-lens reflex camera.

A mercury pump is developed by inventor Heinrich Geissler, to produce vacuum tubes. The first cathode rays will be observed in these tubes, after they are modified and improved by Sir William Crookes.

Engineer Frederick Taylor carries out "time-motion" studies of workers with the idea of making their labor more efficient. He will pioneer the "scientific management" of the workplace.

A railway bridge spanning the Mississippi opens between Rockville, Illinois, and Davenport, Iowa. Abraham Lincoln, a lawyer, will defend the legality of the bridge before the Supreme Court, in response to a "right of way" suit brought by a steamship company.

During Easter vacation from London's Royal College of Chemistry, 18-year-old William Henry Perkin synthesized mauve, or aniline purple — the first synthetic dyestuff — from chemicals derived from coal tar. Mauve was enthusiastically adopted by the fashion industry in England and synthetic dyes quickly destroyed the market for natural substances derived from plants like indigo and madder. Perkin's creation was an accident — he was trying to synthesize quinine.

The "Bessemer process" for making inexpensive steel, which involves using blasts of cold air to decarbonize melted pig iron, is developed by inventor Henry Bessemer.

The 458-mile Wabash and Erie Canal opens after 24 years, and is the largest canal ever dug in the U.S. By 1860, however, sections will begin to be close, and, unable to compete for railroads, the entire Canal will be closed by 1874.
