Normal Your ignorance in the ways of science is perhaps excusable, but allow me to correct you. The study of optics permits Persia to embark units in unwieldy barges safely in coastal waters, thanks to the ability to pre-empt dangerous rocks and so forth. But Persia does not yet have the ability to navigate the deep oceans where there is no geographical reference point for a travelling ship. If you wish to engage in such a foolhardy endeavour as attempting to cross the great ocean with our current knowledge you will end up floating in circles and dying a painful death of starvation and scurvy without so much as a single sight of new land. Furthermore I might add that you are a minister of Persia, and you have as such duties to Persia to fulfil. Forsaking such duties in the name of adventure is a gross discharge of office and does disservice to the King who has put so much trust in you, by giving you a position of power. I suggest you focus on your job instead of on fanciful dreams.
