//January 24, 2011// I have thought about one day getting a tattoo and I'm not sure how I feel about the removable ink. I feel like its kind of defeating the purpose of a tattoo, like the article said. If I were to get one I think I'd want to know that it can't be removed. I think that that adds some excitement to the process. It makes it a bigger decision than it would if I knew it could be removed. As for the scientific part of the article I think it sounds kind of gross to dye your skin when its broken down like this. I also didn't realize how they removed tattoos now. I knew it was difficult but lasers seem excessive... I guess I've watched too much sci-fi.

Kieran, I guess it's go big or go home for you on tattoo's :) If your tastes change it gives you an opportunity to easily change your mind! Good post! 5 stars. MW

//February 8, 2011// I thought it was interesting that the kilogram is the only physical SI artifact. It is intriguing that we have to take so much precaution in official measurements like this. I also thought it was cool how all of the measurements are tied together in many ways. It must have been hard to figure out what scale to use that would make everything mesh and work well together. I don't fully understand the mole yet though.

Kieran, I too wonder about the scale that was used to standardize the mass. We'll do lots with the mole later. 5 stars. MW

//February 25, 2011// This was an interesting topic. I had not really thought about it before now, but I do find it to be enjoyable to learn about. The most intriguing part of the article for me was when they listed the different ways that the sensors work. I never knew that some of them used heat sensors. Another thing that I learned from this article was that the eyes work on an atomic level. I guess I already knew this, but I never thought about it. It said that it pushes around electrons to make chemical reactions. I thought that was cool. Lastly, the article also sparked my interest on other items that I come in contact with often, like elevators and automatic doors, that use types of motion detection. I am glad I read this article and learned more about how common objects work.

Kieran, I'm glad you could see some relevance to the article. Good post! 5 stars. MW
