If you find remains of intelligent alians, you may see their kind of books(*). Could you understand those books? They don't use our character, don't use our math symbols and other scientific symbols. Following images are my experiments to draw my scientific concept without our 'history dependent' information(**).

(*) Of cource it is possible that they don't use visual image to recording.

(**) Imagine pi. Aliens don't use the greek letter pi. Aliens don't use Arabic numerals. The decimal system is not universally used concept. You know 1 feet is 12 inches and 1 hour is 60 minutes. Decimal point is same. Some country use comma instead of period. Left-to-right writing is also same. Japanese mathematician used up-to-down writing. (You can see old math books from 東北大学和算ポータル, some of them are before Leibniz) You know pi is the ratio of the circumference of a circle to its diameter. It is possible to use a ratio of the diamater to the circumference, it is 0.318, or a ratio of area of circle to the area of the circumscribed square, 0.785. What is universal? It is a question.
