The first period Tuesday is Space Propulsion Systems by Professor Soga. I attended his class last year， too. He makes me sleep. In addition， today’s lecture was review of last year so that I was very sleepy.

The second， English Intermediate Course. This class is one of the reasons why I started this diary.

The third is Professor Suzuki’s Electronic Circuit. It hasn’t set in new subject yet.

Precision Processing is fifth， and in spare time I was doing a assignment of Compressible Fluid Dynamics.

The rain stopped， and Egg Fall experiment was held in the third period. But the wind was blowing very hard. A quarter of challengers succeeded， more than I had estimated. I couldn’t be a success， but I’ll do my best at post-experimental paper.

The first and second priods was Designing. We used a CAD software Rhinoceros (http://www.rhino3d.com/).

I’ll have Egg Fall experiment tomorrow. Today I did papercraft， because I can use nothing but a sheet of cardboard (& Cemedine). The sheet is a little smaller than A4 paper. Eggs and instruments are going to dropped from the tenth floor of Bldg. NO.1.

Since now， I’ll write a pre-experiment paper.
