In the deep forest‚ there stands a tree beside a river. It is an ancient tree‚ standing tall against the sky. On its bows grow lush green leaves of thousandth generation. At its base‚ grey roots pile on top of one other like an old man’s beard. A cicada lies on top of a root with its legs pointing uselessly at the sky. An ant happens to walk by. Upon seeing the cicada‚ it promptly turns around to tell its family of the dinner it found. The ant traces its steps and arrives at a tiny hole at the

1. In the piece we listened to for this assignment‚ there are multiple instruments making the sound. Each of them is making a different sound and then when the all come together we get an even better and enjoyable sound. There is the Piano‚ Violin‚ cello‚ flute‚ and Tuba in this piece of music from what I could see.

Run!” My lungs burned‚ but again‚ I couldn’t stop

Physics began when man first started to study his surroundings. Early applications of physics include the invention of the wheel and of primitive weapons. The people who built Stone Henge had knowledge of physical mechanics in order to move the rocks and place them on top of each other. It was not until during the period of Greek culture that the first systematic treatment of physics started with the use of mechanics. Thales is often said to have been the first scientist‚ and the first Greek philosopher
