At KyuRyu Aikibudo we have been busy this week. Kono Sensei last weekend. We installed the new mats this week. Waddell Sensei is in town to train. Shibata Sensei is lecturing this weekend. Not much time for blogging I am afraid.
However I did find this film about the physics of an arrow, that I thought was really amazing. How does energy transfer down a shaft and remain stable in air?
