This Month in History
January holds many revolutionary historical moments in the world of technology, below are just a few we have picked out.
The Davy Lamp- Being the first safety lamp invented for miners, the Davy lamp was quite impressive as it was made to decrease the chance of explosion or asphyxiation due to gases, such as methane, in the mines. The Davy lamp was first proposed in 1815 by Sir Humphrey Davey, and underwent initial trials in January 1816. It had a simple design, the flame was surrounded in a steel mesh screen that allowed air through and stopped the flames from escaping, therefore decreasing the chance of explosion. The lamp was also designed to make the flame go out when the oxygen levels got lower than 17%, which is still a safe level for the miners, allowing them time to leave the mines.
London Underground- On January 10th 1863, the world’s first underground railway service in London, being the Metropolitan line between Paddington and Farringdon. This is now part of the Circle, Hammersmith & City and Metropolitan lines. The systems first tunnels were built just below the surface, using the cut-and-cover method; later, smaller, roughly circular tunnels were dug through as a deeper level, which gave rise to the nickname ‘the Tube’.
Apple- In more recent history, Apple celebrates the 10th anniversary of the release of the original iPhone beginning the smartphone revolution that we are currently in. The iPhone was revealed in the 2007 Macworld convention in San Francisco. Steve Jobs called the iPhone a “revolutionary and magical product that is literally five years ahead of any other mobile phone”. Since then Apple have unveiled more technologically advanced and innovative products and continued to increase sales.
