Boltzmanns Atom: The Great Debate That Launched A Revolution In Physics [Hardcover]

The author gives a readable account not only of Boltzmann's life and work but also of work and philosophy of those scientists who opposed his theory, developed a similar theory, or confirmed his hypothesis, James Clerk Maxwell, Wilhelm Ostwald, Ernst Mach, Josiah Willard Gibbs, Max Planck and Albert Einstein among them. Thus readers can get good understanding about Boltzmann's depressive mood and the significance and greatness of his work. The conflict between Boltzmann's atomic hypothesis and Mach's philosophy that science should be based only on observable facts is discussed especially in detail in this book.

Lindley teaches us that a similar conflict also exists nowadays. Namely, he writes in Chapter 7, ". . . now some physicists argue for the existence of superstrings and other curious entities that will never be seen directly. It remains, even now, a profound question whether the cost of proposing such very hypothetical objects as superstrings is sufficiently compensated by the benefit in understanding that the hypothesis brings." Here he insists the merit of Mach's critical attitude. In Postscript, however, the author stresses the legacy of Boltzmann's difficult victory over Mach in the modern idea of theoretical physics. Readers are thus made think by themselves about the merit and demerit of Mach's philosophy and physical hypotheses. The book would be interesting to both laypersons and working physicists.

Yet today atoms are not at all controversial, since scientist have not only proved they exist but that they are complex and made of sill smaller elements. But why was this Dr Boltzmann? Having seen his picture he was a handsome man. Tall dark and handsome to be exact. Wore glasses and was a quite man. He was born Feb. 20, 1844, in Vienna, Austria and died Sept. 5, 1906, in Duino, Italy. His achievement was in the development of statistical mechanics, which explains and predicts how the properties of atoms (such as mass, charge, and structure) determine the visible properties of matter (such as viscosity, thermal conductivity, and diffusion). As an avid atomist, Boltzmann's fervent belief in his work led him into many heated debates with his colleagues. While he had interests in philosophy were far reaching, even delving into the function of language; ultimately he was a theoretician and physicist. He did not consider himself a philosopher and was critical of philosophy as a science.

Around 1881, Boltzmann efforts were associated with J.C. Maxwell. Maxwell worked to try to explain the thermodynamics of gases. Boltzmann introduced the Ehrenfest urn Model, an example is the probability formulation in Markov chain terms. A discreet parameter stochastic process is a collection of random variable {X(t), t=0,1,2,3,..}. The values of X(t) are called the states of process. The collection of states is call the state space. The values of t usually represent points in time. The number of statis either finite or countable infinite. A discrete parameter stochastic process is called a Markov Chain if for any set of n time points t1<t2<....>tn, the conditional distribution of X(tn) given values for X(t1), X(t2),... X(tn) depends only on X(t(n-1)). It is expressed by

P[X(tn)<=xn\ X(t1)=x1,...X(t(n-1))=x(n-1)]

=P[X(tn) <=xn\ X(n-1)=x(n-1)].

A Marko Chain is said to be stationary if the value of the conditional probability P[X(t(n+1))= x(n+1)\X(tn)=xn] is independant on. This is for stationary Markov Chains. He was the first one to recognize the importance of Maxwell's electromagnetic theory. Trivia: The Boltzmann constant has a value of 1.380662 * 10^-23 joules per kel vin.

And this is what the book is basically all about. The man. The genius and how he changed the world of math and physics. In Vienna Dr Boltzmann taught not only physics but in 1903 he also committed himself to teach a university course "Methods and General Theory of the Natural Sciences." Boltzmann constant was named after Lugwig Boltzmann, because he substantially contributed to the foundation and development of statistical mechanics, a branch of theoretical physics.
