SOLVING LONGITUDETime for a story…

What is latitude?

• North/South position of a point on the earth• Relatively easy to determine

What is longitude?

• East/West position of a point on the earth• Easy on land, but hard to determine at sea

Why was this a problem?

• Slowed down journeys• It could be solved with clocks• The sea fluctuates• Led to many shipwrecks

Enough was enough!

• By the 1700s, sea trade was too valuable• A prize was announced for £20,000 (£2.87

million)

Enter John Harrison

• 1693 – 1776• Trained as a carpenter

The Harrison clock(s)

• 1730• Used some wooden

components• No pendulum

Finally… The Sea watch

• 1759, Harrison is now 66

• 5.2”• A considerable feat of

engineering

Trials and Tribulations

• Trial after trial…• Clocks vs Sky• Fighting the establishment• Captain Cook• Cost• Took until the 1800s to finally be recognised
