Had another very confusing day to do with forces, accelerations and inertias. At the end of it though I have something that seems to work reasonably well. It will certainly do for testing at the moment.

Er, walked the dog. Went and did Body Pump. Which is really the first kind of exercise I’ve done this week since combat. Still feeling a bit sick, but kind of on top of it now.

Another late finish, but will make up for illness this week.

Bath and wine time. Busy DIY weekend ahead.
