Read about how to make Schrödinger’s equation physically meaningful + computable here.

   Violation of the PLA of the capitalistic system in 1929.  The Principle of Least Action (PLA) expressing Stationarity of the Action (the integral in time of the Lagrangian), with the Lagrangian the difference between kinetic and potential energies, is cherished by physicists as a deep truth about physics: Tell me the Lagrangian and I will […]

The reader will find no figures in this work. The methods which I set forth do not require either constructions or geometrical or mechanical reasonings: but only algebraic operations, subject to a regular and uniform rule of procedure. (Preface to Mécanique Analytique) The Principle of Least Action formulated by Lagrange in his monumental treatise Mecanique Analytique (1811) collecting 50 […]

Bohr plotting the Copenhagen Interpretation of quantum mechanics together with Heisenberg and Pauli (left) and Bohr wondering what he did 30 years later (right). To view physics as a form of analog computation which can be simulated by digital computation offers resolutions of the following main unsolved problems of modern microscopic and classical macroscopic  physics: […]

 John Bell’s Against Measurement is a direct attack onto the heart of quantum mechanics as expressed in the Copenhagen Interpretation according to Bohr: It is wrong to think that the task of physics is to find out how nature is. Physics concerns what we can say about nature… Bell poses the following questions: What exactly qualifies some physical systems to play […]

Leibniz develops a solution of the mind-body problem arising from the dualism of Descartes as an analogy to the well known physical phenomenon of resonance between two pendula or tuning forks swinging in perfect harmony together:  Leibniz World is a world in such perfect harmony, and as such a Best of Worlds, with everything in […]

Combined gravitational potential for Earth–Moon system with Lagrange points. Motion under gravitation is according to the New View described by the following set of equations in terms of the gravitational potential and immaterial free fall trajectories ; ,                         (mass conservation) , ,       […]

Schrödinger’s equation as the basic mathematical model of quantum mechanics of a system of interacting particles (electrons and kernels), is commonly motivated as an analog to a classical -body problem with classical momentum translated to the spatial gradient of a 3N-dimensional wave function depending on 3-dimensional space variables ,  with the dependence on supposed to describe […]

England vs Germany during the 1s World War: Sopwith Camel vs Fokker DVII Scout Single Foreword to the book The Secret of Flight: I have not the smallest molecule of faith in aerial navigation other than ballooning or of expectation of good results from any of the trial we hear of. (Lord Kelvin refusing to join the […]

Kelvin’s Circulation Theorem states that the vorticity of incompressible inviscid flow is preserved in a fluid without exterior forcing (subject only to inertial and pressure forces). Kelvin’s Theorem is presented as a corner stone of the Kutta-Zhukovsky circulation theory of lift. The proof consists in taking the curl of the momentum equation of the incompressible […]

The text book theory describing the generation of lift by a wing is the Circulation Theory (CT) developed by Kutta-Zhukovsky more than 100 year ago. The New Theory of Flight shows that CT is unphysical and incorrect: Lift is not generated by large scale circulation around a wing section. There is no physical mechanism generating […]

The Enigma of the Aerofoil: Rival Theories in Aerodynamics 1909-1930, by David Bloor, 2011, describes the initial British criticism of the German circulation theory of lift developed by Kutta and Prandtl in the beginning of the 20th century, which resisted the attack in the absence of something better and became the leading theory propagated in […]

Listen to Euler describing his equations: Everything that the theory of fluids contains is embodied in the two equations I have formulated. It is not the laws of mechanics that we lack in order to pursue this research, only the analysis which has not been sufficiently developed for this purpose. We have to wait until the […]

The New Theory of Flight offers material for reflections on the philosophy of science, as sketched in the previous posts Kuhn on New Theory of Flight and Popper on New Theory of Flight. More generally, let us reflect on the relation between philosophy of science and science. It is natural to expect that the philosophy […]

Listen to Birkhofff expressing his criticism of Prandtl and modern fluid mechanics. The mathematician Garrett Birkhoff addresses in the opening chapter of his book Hydrodynamics from 1950 several paradoxes of fluid mechanics including d’Alembert’s paradox, and expresses a clear doubt in their official resolution attributed to Prandtl: I think that to attribute them all to the neglect of viscosity is […]

The New Theory of Flight is now confronting the ruling paradigm of aerodynamics formed by the Fathers of Modern Aerodynamics Kutta, Zhukovsky and Prandtl, which has dominated all through the 20th century into present time. The New Theory is based on computational solution of the Navier-Stokes equations and thus represents information society, while the Old […]

Modern aerodynamics formed by its fathers Kutta, Zhukovsky and Prandtl, resulted from a crisis of classical mechanics with the prediction of zero drag and lift in slightly viscous flow falsified by observation as expressed in d’Alembert’s paradox. To resolve the paradox two ad hoc assumptions were introduced: An airfoil with sharp trailing edge will generate […]

Two unique short videos with the Fathers of Modern Aerodynamics Prandtl and Zhukovsky speaking, have recently been put up on Youtube: Prandtl Discovers the Boundary Layer Zhukovsky Discovers Circulation Generated by Sharp Trailing Edge. See also Nikolay Yegorovich Zhukovsky.

The slides for my talk at Variational Multiscale and Stabilized Finite Elements VMS 2012 at Christian-Albrechts-Universität zu Kiel is now available for inspection.

Let us see how Wikipedia handles the fact that there is no convincing explanation of how a wing generates large lift at small drag, which makes it possible to fly for both birds and airplanes. We quote from Lift Force: There are several ways to explain how an airfoil generates lift. Some are more complicated […]

A common feature of pseudo-science is theory claiming a substantial effect from a small or unknown cause making experimental testing impossible. Let us subject modern fluid dynamics to this test. Modern fluid and aerodynamics is dominated by Ludwig Prandtl named Father of modern fluid mechanics and Zhukovsky named Father of Russian aerodynamics supported by his […]
