Tomorrow’s Leaders Today: María de la Cruz Salinas Deanda
By Robin Loving
Tomorrow’s Leaders Today focuses monthly on outstanding local honors students who have earned university scholarships from Jóvenes Adelante which seeks to break the cycles of poverty into which the students have been born. This is the story of Maria de la Cruz Salinas Deanda, a mechanical engineering major with a specialty in design and simulation at ITSES (Instituto Sanmiguelense), an outstanding local university. Her letter came to Jóvenes Adelante unbidden.
“First I want to thank Jóvenes Adelante for all that you have done for me. I want to show you a little of what I do in school in the robot workshop, my design class, and my computer simulation class. With only three girls in the group, I am always very motivated to excel. The school recently grouped us with students from Texas A&M University. Here are excerpts from a paper I wrote in English and Spanish on mechanics and sound.
As a violin player I am fascinated by sound (Deanda is a violinist in the prestigious Cervantes Festival annually!). First of all I’ll explain what sound is. Physiological sound is an auditory sensation made by a wavelength in the air. Some important vocabulary:
Reflection is when waves bounce making echo and reverberation. Refraction is when waves deviate because of a variety of environmental factors. Diffraction is when waves skirt objects.
In order for a sound wave to propagate, its medium has to be elastic and have mass and inertia. The air also has some important features for sound propagation: a linear speed. Sound waves are longitudinal. In the presence of reflective surfaces, waves stop being spherical and become extremely complex due to the overlap with reflections. Sound pressure is the pressure that must be added to the atmospheric pressure to obtain the actual value of atmospheric pressure in the presence of sound.”
Deanda went on like this for pages, and the material was so densely scientific that it would bore most of us. Suffice to say that this aspiring professional is learning her stuff! Thanks, San Miguel, for supporting the Deandas of this world through Jóvenes Adelante.
