When was the railway engine invented?
The history of the steam engine stretches back as far as the first century AD; the first recorded rudimentary steam engine being the aeolipile described by Greek mathematician Hero of Alexandria. In the following centuries, the few steam-powered "engines" known were, like the aeolipile, essentially experimental devices used by inventors to demonstrate the properties of steam. A rudimentary steam turbine device was described by Taqi al-Din in 1551 and by Giovanni Branca in 1629. Jerónimo de Ayanz y Beaumont received patents in 1606 for fifty steam powered inventions, including a water pump for draining inundated mines. Denis Papin, a Huguenot refugee, did some useful work on the steam digester in 1679, and first used a piston to raise weights in 1690
He didn't. The steam engine was invented by James Watt in 1712. Trevithick developed an improved high pressure steam engine in 1800. He then invented the steam locomotive in 1803 and actually built a passenger railway in London in 1812. Thomas Newcomen gave his name to atmospheric steam engines, which he invented. The first was installed in 1712 close to Dudley Castle in the Black Country. He had to share his success with Thomas Savery…
Hi. In 1888, the first police dog was used in England and I am just fascinated as to the first case to which a police dog was assigned. The London Metropolitan Police Force first used two bloodhounds to track suspects by their scent as part of the Jack the Ripper investigation. The Ripper was never caught, but the use of dogs as part of the Met continued.
