Yes, it is the second day of the Sci/Art Nano Lab and although I may be tired right now, I should expect a lot more. The primary activity we did was take a usual visit to the auditorium. Expecting another long lecture, I was bewildered to enjoy the time with Mattia ad Rita. When I came into the room I was not conversant with the subject of waves. Nevertheless, when I found out the unique variations in each, I was entirely astonished. Speakers Rita and Mattia explicated how sound can depict an image and vice versa. There are mechanical waves, which are influenced by sound (change in pressure) and it was also ascertained that the different wave lengths can affect the shape and color of each wave. http://paws.kettering.edu/~drussell/Demos/waves/wavemotion.html.
During the conception of the lecture, I did not comprehend what an octave really had to do with waves. http://en.wikipedia.org/wiki/Octave. I grasped, after the presentation, that an octave is the interval between one pitch and another pitch and half (or double) the frequency. http://www.youtube.com/watch?v=s9GBf8y0lY0. Therefore, with the example of the plant reacting to different sounds, I perceived an idea of the impact sound has on different species.
An additional topic encrusted in class was, ferrofluids. I knew that some time during my stay here we would be conducting experiments, but I never really surmised something so artsy/scientific at the same time. So, with that theme in mind we all conducted an activity in class, which was the ferrofluid lab. http://www.ferrotec.com/technology/ferrofluid/.
I was informed that a ferrofluid is a liquid that responds to a magnetic field=colloidal (nano-particles) suspension of superparamagnetic magnetic material. There are also three processes involved 1.) Nucleation 2.) Growth 3.) Termination. At first, while completing the experiment, we had a little mix up with the chemicals involved. I was really anxious to see what kind of reaction would befall. Generally, yes it was a little disappointing to wait and receive not a single chemical change, but in the end the right substance was replaced with the mistaken one. The final product was genuinely amazing. I had never seen such art with a hint of scientific approach at the same time.
With all of the other lab visits that we visited, I enjoyed seeing all of the different nano-systems at work!
