Lee's Apartment
Mike and I finally found ourselves an apartment (Well, Maritza actually found it...). It's on the tenth floor and about a two-minute walk from the metro station. It has big windows facing in three directions, so we can see the smog all over! These pictures were taken from my apartment at sunrise on a very clear day.

My Machine
I've finished up one week of work now, and so far I've mostly just set up my experiment. It's basically a thin plastic sheet rolled into a cylinder and very carefully glued to itself. It's held in place by the aluminum contraption shown on the left. Almost all the metal pieces were machined here for the previous experiment (in which they twisted the column to see how it would buckle). My experiment involves poking the cylinder with the two micrometer screws shown on the right. You should be able to see that one screw rotates with the cylinder, and the other is fixed to the supporting rod on the right. Somehow I'll measure the force that they exert and how that changes when I rotate the cylinder (and one of the screws) so that the dimples aproach each other. When they get close enough to each other,
they'll annihilate and become one. As of now I haven't started taking any data, but hopefully that will begin soon. I've been reading lots of papers on thin surfaces and could tell you all about what happens when you deform them, but it would be difficult and probably uninteresting over a blog. You should be able toclick on the pictures to make them bigger. Post a comment if you have any questions!
Welcome
Hello everybody!
Lee wanted me to write the first post on our blog, so here it is. We've been in Chile almost two weeks, and we're just now starting to have time to breathe. That is, we'd have time to breathe if the air weren't so polluted. Lee has a cough, which we think is due to the air. Here in Chile they have an inversion that lasts the entire winter. Due to the fact that it hasn't rained for several days, the air quality is low, so that we can't see the mountains around the city. I've never experienced this phenomenon (although my parents yawned when I told them – the weather is the same as in Los Angeles).
I want to leave you on a good note, so here's a little story about bread. Yesterday Lee, Mike and I went to the Jumbo (like a Super Wal-Mart without the "Home & Garden" section and with more food in its place) where we bought two loaves of "pan de campo" for just 340 pesos each – about 75 cents! Today I went to a bakery on my way home and bought three Berliners. They're rolls with a sugar icing or manjar inside. They only cost 300 pesos each.
OK, Lee wants to translate the post, so wait for him.
Seeya,
Maritza

Bienvenidos
¡Hola a todos!
Lee quiere que yo escriba la primera entrada en nuestra blog, entonces aquí es. Tenemos casi dos semanas en Chile, y sólo ahora empezamos a tener tiempo para respirar. Digo, tendríamos tiempo para respirar si el aire no fuera tan tóxico. Lee tiene un tos, pensamos que es debido al aire. Acá en Chile hay una inversión que persiste durante todo el invierno. Gracias al hecho que no ha lluvido por varios días, la calidad del aire es bajo, tanto como no podemos ver las montañas alrededor de la ciudad. Nunco he experimentado este fenómeno así (aunque mis padres bostezaron cuando les dije el cuento - el tiempo es igual en Los Angeles).
Quiero dejar ustedes con una buen noticia, entonces escribo un poquito sobre el pan. Ayer Lee, Mike, y yo fuimos al Jumbo (como un Super Wal-Mart sin equipo para "hogar y huerto" que tiene más comida en vez de eso) donde compramos dos barras de "pan de campo" por sólo Ch$340 cada uno - ¡sobre US$0.75! El día de hoy visité una panadería en mi camino hasta la casa, y compré tres "pan berlin". Son como bollos con azúcar glas o manjar adentro. Cuesta sólo Ch$300 cada uno.
Bueno, Lee quiere traducir la entrada, le esperan.
