It was a dangerous business, because the ship's captain often had little idea where they actually were and they ran into rocks with depressing regularity.<\/p>\n<p>They needed better clocks, better measurement and above all, better mathematics.<\/p>\n<p>This video gives us a quick overview of some of the key mathematical discoveries of this period - trigonometry and logarithms.<\/p>\n<div class=\"videoBG\">\n<iframe title=\"YouTube video player\" width=\"480\" height=\"303\" src=\"https:\/\/www.youtube.com\/embed\/AGCUm_jWtt4\" frameborder=\"0\" allowfullscreen><\/iframe>\n<\/div>\n<p>This video is one of the highly recommended <a href=\"http:\/\/blog.ted.com\/8-math-talks-to-blow-your-mind\/\">8 Math Talks to Blow Your Mind<\/a> by TED.<\/p>\n<p class=\"alt\"><a href=\"#respond\" id=\"comms\">Be the first to comment<\/a> below.<\/p>\n","protected":false},"excerpt":{"rendered":"<p><a href=\"https:\/\/www.intmath.com\/blog\/videos\/friday-math-movie-how-does-math-guide-our-ships-at-sea-8182\"><img loading=\"lazy\" src=\"\/blog\/wp-content\/images\/2013\/06\/ship_th.jpg\" alt=\"How math guides ships at sea\" width=\"128\" height=\"100\" class=\"imgRt\" \/><\/a>Here's an important use of mathematics in the real world - navigation at sea.
