Nautilus technical ref lite for Android

Nautilus technical ref lite app for android description: Nautilus is one of the fastest growing technical reference applications in the android market.
It is being developed to cover a broad range of technical subjects with regular high quality content updates.
Current content (note that some items restricted to pro version only): arithmetic: number systems rules of signs laws and operations fractions powers roots geometry (2d 3d) analytical geometry anatomy of a circle circular conical coordinate system: cartesian coordinate system: polar cuboid cylindrical geometric construction of algebraic expressions polygons pyramid quadrilaterals scalars spherical vectors trigonometry laws ratios identities graphs of functions signs of functions unit circle constants and units prefix multipliers si units derivative constants greek symbols optics mirrors lenses optical distance laws light spectrum refractive index laws of reflection refraction physics expansion of solids and liquids forces (static impulse centrifugal centripetal etc) force interactions power work done gravity momentum velocity speed acceleration mass inertia weight speed specific gravity temperature newton 39 s laws kepler 39 s laws frequency bands pendulum (simple) projectile motion rotational forces mechanical transmission (ratios torque efficiency) electronics resistors resistor networks capacitors inductors logic gates heat sinks operational amplifiers switches laws (ohm 39 s and kirchoff 39 s) leds rectifiers transistors (will be expanded) diodes active filters (basic and classic) low pass high pass band pass and notch.
