东坝大马灯不仅是各种舞台上的表演，更是寻常生活。如今每周五，东坝中心小学操场上总是热闹非凡，孩子们两两一组披上道具，马背上不坐人，却也能把战马演得逼真神气，这份传承让汤春山欣慰。学校“大马灯社团”每年招收四年级小学生，他和退休教师陈洪斌一起讲课，已经带了三届。在学校支持下，竹马被重制，也有了适合儿童的“迷你马灯”课程和道具。为方便远游演出，完整表演队需要的156人规格被精简到40多人。东坝街道还建立了大马灯陈列馆、民俗文化馆，大马灯还走进了高淳博物馆和初中大思政课课堂……，详情可参考旺商聊官方下载
Leonardo da Vinci is usually credited with conducting the first systematic study of friction in the late 15th century, a subfield now known as tribology that deals with the dynamics of interacting surfaces in relative motion. Da Vinci's notebooks depict how he pulled rows of blocks using weights and pulleys, an approach that is still used in frictional studies today, as well as examining the friction produced in screw threads, wheels, and axles. The authors of this latest paper used an experimental setup similar to da Vinci's.
Directed by Phil Lord and Christopher Miller, Project Hail Mary stars Ryan Gosling as Ryland Grace, a middle school science teacher who wakes up on a spaceship millions of miles from Earth with no recollection of how he got there. As his memory slowly returns, he pieces together his mission: save Earth from the alien microorganisms causing the sun to die out.

It's a story about survival and unexpected friendship, and you may want to bring some tissues along.
