The Longitude Problem by John D.

In 1546 Henry founded Trinity College at Cambridge, and John was admitted in the first class. Roland became a regular part of Henry's court, which meant that young John was afforded a fine education. After graduating from Trinity, he made for the continent, studying at Luven and in Paris buying books. He learned about navigation, a subject which England was very far behind on,. The tutors ruled the country, and they were generally suspicious of things mathematical as being sorcery.
