Part 2.1 What David is trying to get acrossed is that when you look at things at different scales you then you get different answers for each scale. For example the picnic level or normal level is different the 1000 light years away. And how a single carbon atom mis diffrent from that compared to 100000 light years.

The main ideas is that diffrent scales you view the more vast and detailed they are. So if you look at the earth you get a bigger idea and less details also vice versa. 

I had the same ideas from the powers of ten essay and the scales essay.

It extends my learning on how I can view diffrent things on diffrent scales in both the past and the present do know diffrent areas of importance of diffrent things

2.2 he uses scales in his two essays but he is focoused more on the surface  or the vast things not really teenie tiny details like the powers of ten does. 

I think he does agree with David in some ways more than other David is more dead set on accuracy I think where fernand is more set on the surface like the picnic level almost not going down to the nano or microscopic level just normal. 

I think they do support each other views but their thought processes vary because no one thinks Alike fernand didn't want to go as in depth as David did

He would have stopped at 2 because he didn't want to go too small of detail but not in great depth either
