Crazy when you understand it


@David_Kicinski Science didn't claim to be a source of morality.






Cartesian, cylindrical, and spherical coordinate systems each describe positions in three-dimensional space with variables matched to symmetry. Cartesian uses three linear coordinates x, y, z. Cylindrical replaces the horizontal plane with radial distance ρ and angle φ while keeping z. Spherical uses a single radial distance r, polar angle θ, and azimuthal angle φ. The image provides the standard conversion formulas between all three pairs of systems. These conversions are routinely applied in GPS receivers, which translate satellite data from spherical coordinates into Cartesian coordinates to determine a user's exact location on Earth.



@gomiam @AntiDisinfo86 Check your facts - and the JPL Horizons database - buddy. You'll find the path that the Apollo 12 third stage took, from liftoff to separation after the 'trans lunar injection' allegedly took place, was directly toward the Moon from Earth 'orbit'.





















Just a coincidence right?




Me ha sorprendido muchísimo el rechazo tan alto a la medida de @oscar_puente_ de permitir que perros grandes viajen con RENFE. No entiendo esta oposición tan extrema a poder hacer vida con nuestros seres queridos. Por cierto: esta iniciativa es una grandísima medida ecológica*.
