The physics inside piano website

Presentation: The purpose of  creating this site

A graduate thesis follow up

I decided to publish in the world wide web the Physics graduate thesis I've got in the University of Rome, Italy, in 2005 at the Mathematics, Physics and Natural Science faculty. My deepest motivation to do this is to continue to do research in the future, perhaps in conjunction with some educational institution somewhere. The thesis subject regards a new physical model of the grand piano action mechanism. Arriving at the end of my studies at the university, and given that in the past years I have been involved in the repair and piano tuning, persuaded by my professors and inspired by the discussions with my companions of faculty I decided to go ahead with this argument to obtain the degree, and now I would like to show it on the web, to probe any chance of working with all this. I would like to interchange ideas in this online context about all thesis related matters. One SQL database is under construction for discussions and will be working soon I hope.

For the development of the site academic original contributions are encouraged; granted this is an independent non-profit independent academic activity, for the maintenance of web hosting economic donations are well accepted (contact me). It has been attempted to build up all pages the most easy to read as possible and render the surfing comfortable in a rather circular architecture. 

I am happy to see that this work has sparked out some competition jealousy, as some envious eyed poets already have criticized me that my current english is not quite that of Oxford style speakers, I do not care about at all, the choice to translate the original work from italian is purely practical. The whole thesis document is available in pdf format in the download window in both, italian and english. 

As far as academic contents concerns, the fields of study of piano playing as a physical phenomena embraces many areas of pure and applied mathematics, p.e. the flux of the point of touch is focused on the study on symmetric cones. This is a subject of growing importance in number theory and multivariate analysis, it embraces Jordan algebra, spherical polynomials, multivariate hypergeometric functions, holomorphic functions on bounded symmetric domains of tube type, and invariant differential operators.

Maintaining this conceptual scheme in mind the thesis I defended begins considering the inertial and dynamic properties of the piano Key in the dynamic threshold, therefore the model is developed with the characterization, piece for piece, of all the piano action structure, and also assuming the closing of the loop with the phenomena attributed or connected to aural aspects as well. The main contribution, I think, has been to model of the magnitudes that describe the acoustic stiffness of the piano action structure, considering the flow as the fundamental asset of the conceptualized theory. I'm interested to contact undergraduate and graduate students and theoreticians in pure mathematics, non-commutative harmonic analysis, Jordan algebras, and multivariate statistics; for further developing of related aspects. I hope this will not be a disappointed expectation for the global crisis that now begins (2007).

Finally I want to mention that the philosophy in developing both, thesis and web site, has been that to always observe intellectual honesty, mentioning wherever I had taken advantage of the work of others full reference. I would suggest to adopt such a philosophy and ethics behaviour to visitors of this site, please feel free to copy and paste literacy here exposed if you need it for legal and non-profit purposes, remembering to quote my name, specially if you use the images I have created and digitized with much love and patience during many working hours in the PC.

Distribution of the thesis is achieved under GNU GPL license agreement. The LaTeX source code for the thesis final document generation is deposited on the central archive at the Physics department of "La Sapienza" university in Rome, Italy (Apache_Red_Hat_server), and can be requested to LAN administrator there for further editing, click here to jump there.

I hope you will find science entertainment here, enjoy your visit, come back soon.

Faithfully yours.

“ Music is an agreeable harmony for the honor of God and the permissible delights of the soul. I have always kept one end in view, namely, to conduct a well-regulated music to the honour of God. There’s nothing remarkable about it, all one has to do is hit the right keys at the right time and the instrument plays itself ... ”   Johann Sebastian Bach (1685 - 1750)
