Reading Nick Woolf's lesson "Rockets to the Moon", one gets inspired by his scientific drive and desire to make things better. When asked to summarize this 12-page lesson in five bullet points and a question, I was appalled. I wanted to fight back. In fact, my first thought was to write this posts as a "3, 2, 1" of reasons why the "3, 2, 1" system is wrong. However, subjugated by the system, as always, here is my brief summary of Woolf's narrative:

<strong>3</strong> things that I learned:
- The multiple mirror telescope (MMT) allows a scientist to observe separate images from each of the mirrors.
- While the atmosphere does degrade the quality of telescopic images, as Don York told us earlier, technological limitations did play their part as well. In some cases, bigger is indeed better.
- Even the smallest details can change the scientists' data. While thin mirrors quickly dealt with temperature variations to produce clear images, thick mirrors were fuzzy days after a cold front had passed.

<strong>2</strong> interesting facts I found:
- Stars eject up to 85% of their initial mass before their nuclear reactions end.
- Scientists must often concern themselves with very non-scientific tasks. The scientists working on the Large Binocular Telescope (LBT) had to take care of a rare red squirrel while running the observatory.

<strong>1</strong> question for Nick Woolf:
- Do you think you would have proffered doing your graduate studies through traditional classroom lectures or did you prefer the independence you had?
