唐‧白居易
賦得古原草送別
離離原上草，一歲一枯榮。
野火燒不盡，春風吹又生。
遠芳侵古道，晴翠接荒城。
又送王孫去，萋萋滿別情。
如果
……
；那麼
。
萬物為天地所生，天地為自然所生，如是誰生自然？ 
存在嗎？？果然『佛說不可說』！！
從〈OLPC〉 到〈sugarlabs〉推動『教育』者未曾停息，也許也許略見『春回大地』的跡象！《 Pi Day is around the corner! 》︰
From Hawaii to New York City and beyond, Pi Day will be here this Saturday, March 14th. To celebrate, there are a bunch of Raspberry Pi events happening across the United States and all over the world. Some of these are big affairs, like at the Computer History Museum in Mountain View, CA and others are small gatherings in libraries or makerspaces. Scan the list below (or view the Raspberry Jam map) to find out if there’s a Pi Day event happening near you:

可能可能即將『天地反覆』？《天地文理聖,時物文理哲？！》︰
《黃帝陰符經》
觀天之道，執天之行，盡矣。天有五賊，見之者昌。五賊在心，施行於天，宇宙在乎手，萬物生乎身。天性，人也；人性，機也；立天之道以定人也。天發殺機，斗轉星移；地發殺機，龍蛇起陸；人發殺機，天地反覆；天人合德，萬變定基。性有巧拙，可以伏藏。九竅之邪，在乎三要。可以動靜。火生於木，禍發必克，奸生於國，時動必潰；知之修練，謂之聖人。
