Reflections on today

Well, today I learn about physics in bridge, there bridges like the draw bridge, bascule bridge, the folding bridge, the curling bridge etc,etc......, when we were building the bridge,  The group communication was not that good as we changed the design of the bridge constantly, 2 members of the group did not explain what they were going to do and they said they will tell us when they built it but later they told us after they built the support. I did not experience any fear or discomfort when working with the team.
