Week 1 Impressions of Links

I especially appreciated the first two links because they were simple to understand for those of us who are not mathematically inclined and who have never really studied physics at a deep level. Although physics fascinates me and I make the effort to try and read books about it, often times I find myself giving up half way into a book because i feel like i can't possibly understand what is going on. It's refreshing to see that there are sites up there that are accessible and people can turn to to understand the crazy world of physics. I think simulations and visualizations are especially impacting ways of helping people understand what is going on around and within ourselves.
