Revista Matematica Universitaria 47, 55-65 (2009), 2012 We define a new class of numbers based on the first occurrence of certain patterns of zeros and ones in the expansion of irracional numbers in a given basis and call them Sagan numbers, since they were first mentioned, in a special case, by the North-american astronomer Carl E.

"Quantum gravity": an oxymoron [PDF]
Spacetime and Substance 4 (2003) 182-184, 2003 I prove that "quantum" and "Einsteinian gravity" are incompatible concepts. Accordingly, the graviton is a mere object of science fiction.

Deformation Behavior of La2O3‐Doped Copper during Equal Channel Angular Pressing
Advanced Engineering Materials, EarlyView.By additions of strengthening elements and/or structure optimization, the mechanical properties of copper can be increased while keeping favorable electric conductivity. By combining addition of La2O3 and processing by equal channel angular pressing, substructure development is achieved, leading to increase in microhardness to more than double the ...

On Dirac's magnetic monopole [PDF]
arXiv, 2003 The electric charge of the quantization condition of Dirac's monopole may have any value, we are not obliged to identify it with the electron charge. Consequently the magnetic charge of the monopole is quite arbitrary: Dirac's monopole is a mere object of science fiction.

Diffusivity, mobility and time-of-flight measurements: scientific fictions and 1/f-noise realization [PDF]
arXiv, 2010 Influence of equilibrium thermal 1/f-type mobility fluctuations on time-of-flight measurements is considered. We show that it can explain experimental time dependencies of transient photocurrents.
