... where mg is the magnitude of Fg and m is the mass of the wire. We also want the minimal field magnitude B for FB to balance Fg. Thus, we need to maximize sinφ in above equation. To do so, we set φ = 90o, thereby arranging for B to be perpendicular to the wire. We then have sinφ = 1, so above Eq. yie ...

... Hilbert Hotel paradox: There is a mountain hotel in Alps, which has infinite number of rooms but all of them are occupied. A tired group of 3 hikers came to the owner asking to stay over. He smiled and said, it’s simple, in no time there will be 3 free rooms. He asked the person from the first room ...

Mathematics of radio engineering
The mathematics of radio engineering is the mathematical description by complex analysis of the electromagnetic theory applied to radio. Waves have been studied since ancient times and many different techniques have developed of which the most useful idea is the superposition principle which apply to radio waves. The Huygen's principle, which says that each wavefront creates an infinite number of new wavefronts that can be added, is the base for this analysis.
