The History of Invention

I had a list of various inventions which were in date order, but the piece of paper on which they were listed was torn in half, one half of which has been lost. Given the list of years in which the inventions were invented and the information below, see if you can match all the inventions with the year in which they were invented.

This is the half I have left, on which is written the years of invention:

1320, 1607, 1710, 1721, 1763, 1764, 1783, 1815, 1841,

1856, 1858, 1876, 1877, 1898, 1899, 1935, 1939, 1941.

Gunpowder, the telescope, pianoforte and the mercury thermometer were all invented before the spinning jenny, the steam engine and the hot air balloon. Steel, the wireless and the sewing machine were all invented before radar and the tank. The miner’s safety lamp, the telephone, gunpowder, steel, dynamite and the sewing machine were all invented before the phonograph and the wireless, the two of which, and the tank, were invented before radar, the jet engine and polyester.

Gunpowder, the spinning jenny, the steam engine, the mercury thermometer and the hot air balloon were all invented before the miner’s safety lamp and the sewing machine. Polyester was invented after dynamite, radar and the jet engine. The pianoforte was invented after the telescope and gunpowder. Dynamite was invented after steel, the sewing machine and the miner’s safety lamp.

Steel was invented after the sewing machine which in turn was invented after the miner’s safety lamp. The wireless was invented after the phonograph, the jet engine after radar, and the telephone after dynamite. The spinning jenny was invented before the steam engine and the hot air balloon.
