Trevithick's steam locomotive runs — 1804
1804

Richard Trevithick's steam locomotive hauls ten tons of iron along a Welsh tramway.

It wins a 500-guinea bet — but the cast-iron rails keep cracking under the engine's weight.

Penydarren is a community and electoral ward in Merthyr Tydfil County Borough in Wales.

First permanent photograph taken — 1826
1826

Nicéphore Niépce points a pewter plate coated in bitumen out of his upstairs window in France.

The exposure takes roughly eight hours, so the sun appears to illuminate both sides of the courtyard at once.

View from the Window at Le Gras is the oldest surviving photograph. It was created by French inventor Nicéphore Niépce between June 4 and July 18, 1827, in Saint-Loup-de-Varennes, France, and shows parts of the buildings and surrounding countryside of his estate, Le Gras, as seen from a high window. The image was created by heliography, a process which Niépce had invented around 1822, and which uses the hardening of bitumen in light to record an image after washing off the remaining unhardened material.

First transatlantic telegraph cable — 1858
1858

The first transatlantic telegraph cable connects Britain and Newfoundland after three failed attempts.

Queen Victoria's congratulatory message to President Buchanan takes over 16 hours to transmit — 98 words.

Transatlantic telegraph cables are undersea cables running under the Atlantic Ocean which were used for telegraph communications.

Suez Canal opens — 1869
1869

The Suez Canal opens in Egypt, connecting the Mediterranean to the Red Sea.

The lavish inauguration party costs Egypt so much money it helps push the country toward bankruptcy within six years.

The Suez Canal is an artificial sea-level waterway in Egypt, connecting the Mediterranean Sea to the Red Sea through the Isthmus of Suez and dividing Africa and Asia. It is the border between Africa and Asia. The 193.30-kilometre-long (120.11 mi) canal is a key trade route between Europe and Asia.

Bell patents the telephone — 1876
1876

Alexander Graham Bell files a patent for the telephone in Washington, D.C.

His patent is filed just a few hours before a rival, Elisha Gray — a timing gap that triggers one of history's longest patent disputes.

The invention of the telephone was the culmination of work done by many different people, and led to an array of lawsuits relating to the conflicting patent claims made by several individuals and numerous companies. Notable people included in this process were Antonio Meucci, Philipp Reis, Elisha Gray and Alexander Graham Bell.

Ford Model T goes on sale — 1908
1908

Ford Motor Company launches the Model T, the first car designed for mass-market America.

Henry Ford famously offers it in any colour — so long as it's black, a choice made purely to speed up drying time.

The Ford Model T is an automobile that was produced by the Ford Motor Company from October 1, 1908, to May 26, 1927. It is generally regarded as the first mass-affordable automobile, which made car travel available to middle-class Americans. The relatively low price was partly the result of Ford's efficient fabrication, including assembly line production instead of individual handcrafting. The savings from mass production allowed the price to decline from $780 in 1910 to $290 in 1924. It was mainly designed by three engineers, Joseph A. Galamb, Eugene Farkas, and Childe Harold Wills. The Model T was colloquially known as the "Tin Lizzie".

RMS Titanic sinks — 1912
1912

RMS Titanic strikes an iceberg in the North Atlantic and sinks on her maiden voyage.

The ship carried enough lifeboats for only about half the people on board — and some of those boats launched half-empty.

The RMS Titanic sank in the North Atlantic Ocean on 15 April 1912. The largest ocean liner in service at the time, Titanic was four days into her maiden voyage from Southampton, England, to New York City, United States, with over 2,200 people on board when she struck an iceberg at 23:40 on 14 April. She sank two hours and forty minutes later at 02:20 ship's time on 15 April, resulting in the deaths of up to 1,635 people, making it one of the deadliest peacetime maritime disasters in history.

Fleming discovers penicillin — 1928
1928

Alexander Fleming notices mold killing bacteria in a contaminated petri dish at St Mary's Hospital, London.

He had left the dish out while on holiday — the life-saving discovery owes itself entirely to a messy lab and a late summer.

Penicillins are a group of β-lactam antibiotics originally obtained from Penicillium moulds, principally P. chrysogenum and P. rubens. Most penicillins in clinical use are synthesised by P. chrysogenum using deep tank fermentation and then purified. A number of natural penicillins have been discovered, but only two purified compounds are in clinical use: penicillin G and penicillin V. Penicillins were among the first medications to be effective against many bacterial infections caused by staphylococci and streptococci. They are still widely used today for various bacterial infections, though many types of bacteria have developed resistance following extensive use.

First nuclear chain reaction — 1942
1942

Enrico Fermi's team achieves the first self-sustaining nuclear chain reaction beneath a Chicago football stadium.

The coded phone message to Washington is simply: "The Italian navigator has just landed in the new world."

Chicago Pile-1 (CP-1) was the first artificial nuclear reactor. On 2 December 1942, the first human-made self-sustaining nuclear chain reaction was initiated in CP-1 during an experiment led by Enrico Fermi. The secret development of the reactor was the first major technical achievement for the Manhattan Project, the Allied effort to create nuclear weapons during World War II. Developed by the Metallurgical Laboratory at the University of Chicago, CP-1 was built under the west viewing stands of the original Stagg Field. Although the project's civilian and military leaders had misgivings about the possibility of a disastrous runaway reaction, they trusted Fermi's safety calculations and decided they could carry out the experiment in a densely populated area. Fermi described the reactor as "a crude pile of black bricks and wooden timbers".

Sputnik launched into orbit — 1957
1957

The Soviet Union launches Sputnik 1, the world's first artificial satellite, into Earth orbit.

Anyone with a shortwave radio can tune in to its beep — and millions around the world stay up at night to do exactly that.

Sputnik 1, often referred to as simply Sputnik, was the first artificial Earth satellite. It was launched into an elliptical low Earth orbit by the Soviet Union on 4 October 1957 as part of the Soviet space program. It sent a radio signal back to Earth for three weeks before its three silver-zinc batteries became depleted. Aerodynamic drag caused it to fall back into the atmosphere on 4 January 1958.
