About Potto

Potto Project NFP is a 501 (c) (3) nonprofit organization utilizing collaborative efforts to write quality textbooks for colleges and practitioners, and operates in the spirit of the open-content movement. Can you imagine taking university classes and not having to pay for your textbooks. This situation is exactly what we in Potto Project NFP are trying to create: free quality textbooks. We are inspired by the open-content movement and we are using the open-content model to drive Potto. On one side, big organizations, such as those controlling the Hollywood media, support laws governing what we find is unthinkable: copyright [essentially] forever. While the driving force behind “copyright forever” is economic, we believe it to be immoral and incompatible with the original intent of the copyright proclamation. We can‘t ourselves slay Goliath. We cannot provide every possible alternative to material that is governed by the “copyright forever”s` forces immediately, but we can do something. Potto is our little something, enabling the availability of quality textbooks for college students and anyone who might be interested. We hope with time we will be able offer most of the textbooks needed. As of 2012 over 73% of the entire world downloads in fluid mechanics (including the various torrents) according to alexa.com, google.com and other web cites such as http://website-tools.net/google-keyword/site/www.potto.org are downloaded from Potto Project.

Currently we have written three textbooks which contain several of the best chapters in the world in the field of fluid mechanics and are available for download. For example, consider that all the textbooks on fluid mechanics provide relationships between bulk modulus (density) as a function pressure and in the same time relate the pressure and the liquid density (weight). However, only Potto Project book has the explanation that connect these two concepts. In addition to these unique explanations, Potto provides auxiliary materials such as the gas dynamics tables (the largest tables collection in the world), Gas Dynamics Calculator (Potto-GDC), etc.

We have found that the traditional books do not insert updated materials and prefer to rely on outdated and inaccurate materials. For example, books in fluid mechanics are still using the Buckingham's theorem as their main base to teach and explain Dimensional Analysis instead of Nusselt's method. Hence, Potto Project gained a new mission, which is to replace the old part of the curriculum dealing with dimensional analysis. Dr. Bar-Meir has developed a new methodology and material explaining the dimensional analysis and has shown why Buckingham theorem provides only a minimum number of dimensionless groups while the improved Nusselt method provides a more complete set of parameters.

The combined downloads of these books is over half a million (December 2009) or a rate of 20,000 copies a month (to see more about the downloads estimate here). Potto books on compressible flow and fluid mechanics are used as the main textbook or as a reference sources in several universities around the world. Below are some examples:

  • Purdue University
  • University of Pennsylvania
  • Johns Hopkins
  • Milwaukee School of Engineering
  • Indian Institute of Technology Delhi
  • The University of Iowa
  • Poznan University, Poznan, Poland
  • Caltech, California
  • Aalborg University, Denmark
  • Queen's University, Canada
  • Sheridan College, Oakville, Ontario, Canada
  • Kafrelsheikh University, Kafr el-Sheikh, Egypt
  • Power & Water University of Technology (PWUT) in Islamic republic of IRAN
  • San Jose State University, California
  • Harvey Mudd College Claremont Colleges, California
  • University of Peradeniya, Sri Lanka
  • Grenoble Institute of Technology, France
  • University of Peradeniya, Sri Lanka

Please send us a note if your university is using/used any of Potto Project books.

In addition, Potto's books are the preferred reference books for many professionals around the world. It is not surprising that many graduate students are using Potto's books for their dissertation and other advanced research projects. For example, Rajat Suri of the Massachusetts Institute of Technology used the Potto Fundamentals of Compressible Flow as the main source to develop his hypothesis.

Potto Project NFP hopes that many others will join our efforts, which can truly benefit the society worldwide.
