Freeman Dyson on Living Through Four Revolutions
Freemon Dyson witnessed many of the big science developments of the 20th century. His connections with Feynman, Crick and Von Neumann among others make for a very interesting talk.

EM Drive – Massless Propulsion Concept
I have seen something about this before but wrote it off as nuts. Looks like now I need to go through the theory as an exercise. OverView The technique described in this paper uses radiation pressure, at microwave frequencies, in an engine which provides direct conversion from microwave energy to thrust, without Read more…

Two Slit Experiment with Quantum Eraser Realized with RF Components
For the optical version see: Home Made Quantum Eraser Experiment Using Laser 2 Slits Polarizer Material I wanted to think about this experiment in terms of RF components to see if there was anything new I could extract. In RF speak here is what happens. Description I.T.O. Standard Radio Frequency Speak Read more…

Derivation of Nyquist 4KTBR Relation using Boltzmann 1/2KT Equipartition Theorem
Steps Derive the value of the square of the voltage on the capacitor Assume the noise voltage on the resistor can be faked up and simulated by an equivalent voltage source driving the circuit with a noiseless resistor. The ideal source is assumed to have uniform power spectral density. Equate Read more…
