- This week we experienced the "Tianguis de Física" through conducting simple experiments.
- Through my understanding "tianguis de física" is method through teaching to get young people interested and undertand the concepts of physics. By conducting these simple experiments one can learn a concept at a more broader stance, then once this spectrum is understood it is easier to get more in depth with that specific concept making the learning process clearer with les confusion.
- Originally a "Tianguis" was an open air market within towns which sold a wide variety of goods. There are still "tianguis's" today but they are more referred to as markets/ mercados. This word applies to physics because through this method it is implied that they're are a wide variety of ways along with questions to help one understand physics, just like the amount of different types of goods you can buy at a "tianguis".

- Ondas de la copa - Este experimento es con una copa con liquido en la copa. Entonces, cuando aplicas fricción a la copa la pared de vidrio vibra y comunica la vibración a la superficie del líquido. Sobre la superficie se propaga entonces una onda.
- Ondas de los palitos - Con un encadenamiento de palitos hay muchas ondas. Las ondas incidentes y reflejadas se superponen y se produce una onda estacionaria. Algunos palitos oscilan con gran amplitud y hay algunos pocos que casi no se mueven.
- Experimento de tubos - estamos construido un instrumento por tubos. Encontramos cuando hay tonos diferentes depende en la talla del tubo. Tambien, El tono de un sonido que escuchamos depende de la frecuencia de la onda sonora. Una onda de frecuencia grande es percibida como un sonido agudo y uno de frecuencia baja se oye grave.
- Ondas de Jabón - Con mucho jabón y agua creamos una onda entre un gancho. Cuando movimos la plana de jabón y agua entre el gancho, lo creó una onda.
Ted Talk
- http://www.ted.com/talks/lucy_mcrae_how_can_technology_transform_the_human_body.html
- Very interesting concept on combining biology with technology. This women, Lucy McRae, is inspired to figure out ways to modify the human body in order to positively transform our human evolution. With the help from other scientists Ms. McRae has designed a perfume which you take orally so when you perspire the scent comes from your pores! Crazy! She also mentioned how she is interested in designing ways against aging, which would be highly popular if completed.
