Cook charts the Pacific

I whose ambition leads me not only farther than any other man has been before me, but as far as I think it possible for a man to go.
James Cook, journal, 30 January 1774
Captain James Cook entered the Pacific on board HMB Endeavour in 1768 with incomplete and inaccurate maps and left it in 1770 having charted and claimed New Zealand and Australia's east coast, along with numerous smaller islands.

Cook was ambitious but he also had many advantages that the sailors who went before him had lacked. He was sailing in a ship well-suited to exploration — a flat-bottomed collier that could carry a large cargo yet be manoeuvred close to shore for charting. He understood the importance of a good diet and sanitation to the health of his crew. He carried the latest scientific equipment to aid navigation, and newly created mathematical tables that allowed for the accurate calculation of longitude. He was also an excellent mathematician, astronomer and cartographer who had honed his skills with the British navy in North America.
