Escritor, palestrante e consultor de marketing. Definido como um dos maiores consultores palestrantes na área de marketing e vendas do Brasil, onde é citado pelo americano Phill Kotler, a maior autoridade em marketing do mundo. David chega a fazer 15 palestras por mês e concede inúmeras entrevistas na mídia nacional e internacional. O segredo da Banca de David que é reconhecida mundialmente, foi desvendado. "O segredo é se destacar sempre dos concorrentes", conta David. "O sucesso de um produto está em saber lidar com o publico". "O cliente é mesmo um Rei e não tem conversa. É preciso ter transparência, então não mostre aquilo que não pode oferecer. Os clientes gostam sempre de boas novidades, por isso devemos surpreende-los a toda hora" orientou.

Maxwell's Equations and Electromagnetic Waves I

 Fundamentals of Physics, II (PHYS 201) Waves on a string are reviewed and the general solution to the wave equation is described. Maxwell's equations in their final form are written down and then considered in free space, away from charges and currents. It is shown how to verify that a given set of fields obeys Maxwell's equations by considering them on infinitesimal cubes and loops. A simple form of the solutions is assumed and the parameters therein fitted using Maxwell's equations. The wave equation follows, along with the wave speed equal to that of light (3 x 10^8), suggesting (correctly) that light is an electromagnetic wave. The vector relationship between the electric field, the magnetic field and the direction of wave propagation is described. 00:00 - Chapter 1. Background 04:43 - Chapter 2.

9. Magnetism II

 Fundamentals of Physics, II (PHYS 201) The mechanism by which electric currents produce a magnetic field (Law of Biot-Savart) is discussed in greater detail. The field due to a single loop and an infinite wire are computed. Ampere's Law is derived. The operation of the DC electric motor is used to illustrate the torque generated on moving charges in a magnetic field. 00:00 - Chapter 1. Review of Magnetic Fields 14:00 - Chapter 2.

11. Lenz's and Faraday's Laws

Fundamentals of Physics, II (PHYS 201) The electric effect of a changing magnetic field is described using Faraday's Law. The direction of the current so generated is given by Lenz's Law. The operation and energy accounting of the generator are described. The concept of inductance is introduced. The Betatron is described as an example of Faraday's Law. Self and mutual inductance are introduced. The energy density in a magnetic field is derived. 00:00 - Chapter 1. Review of Lenz and Faraday's Law 25:37 - Chapter 2.
