In My Own Words:
Well, let's be brief, I like reading and I enjoy coffee and eating and listening to music. I study chemical engineering and, for those who might wonder, I have, in fact, tried to explain entropy to strangers in casual conversations. I also certified as an EMT when I was 18, but have abanoned the ambulance due to my career. I speak english, french, spanish, portuguese and german, and have taken a l… Read more

Introduction to Chemical Engineering Thermodynamic&hellip by J. M. Smith
2.0 out of 5 stars Useless, May 9 2004
Ok, so i am a chemical engineering student, and this is supposed to be the textbook. Which allegedly would later on make it a forced reference for a student. However, the only useful information is the steam tables, because the properties and other things are insufficient, trust me, the book has sitted on my shelf unused for a year and a half. I have not sold it because no one here would buy it. The explanations are poor. If you want to know about thermodynamics, this is really not your book, I would rather recommend a Fisicochemistry book.
As for properties tables and the such, well, the information you are really going to use is all summed up in the Chemical Engineer's Handbook,… Read more
Relativity: The Special and the General Theory by Albert Einstein
5.0 out of 5 stars Not Just science, Nov. 29 2003
I won't lie to you, the theory of relativity is not simple. The special relativty is easily understood, yet it is a topic covered in university as an speciality in majors more involved with physics, and general relativity is coverd in masters. Both topics can be quite esoteric, and the mathematical explanation for the relativistic deformation of the time-space due to speed uses Fourier's transforms, so most people will have to just have faith in what Einstein is trying to explain. However, he does simplify the subject enough, so anyone with a basis of physics could grasp some of the most important ideas behind his theory.
Furthermore, this book is important in the fact that by proving… Read more
Hitlers Pope by John Cornwell
Hitlers Pope by John Cornwell
This book is quite clear on the real history of Pius XII, I believe the name in english is not quite fair, the translation to spanish ends up meaning "the true history of Pius XII" which would do more justice to the book. The book has nothing of a prejudice, in fact the author begins explaining that his belief was that he would redeem the historical paper of Pius XII, yet he found that the church itself had been infected by some of the moral relativism that was profetized by Nietzsche, initiated by Einstein's theory, and gave rise to the despotic regimes of the twentieth century.
