    B Ideal Base for a Number System

    I was wondering something a bit different: how does one determine whether a "wrong" answer in base 10 could be a correct answer in another base? I always liked the Ma Pa Kettle math problem where 25/5 = 14 or where 14+14+14+14+14 = 25. Is there a base in which this is valid? If so, how does...

    B How can ice cool an alcoholic drink below 0°C?

    I' I'm not sure if I understand this: correctly: " Water freezes at 0oC. Which is an endothermic process." Freezing (liquid to solid phase change is an exothermic process), while melting is endothermic. Please correct me if I'm wrong.

    B How can ice cool an alcoholic drink below 0°C?

    How about this: freezing is exothermic reaction, latent heat is given off. Melting is an endothermic reaction. So when ice is added to alcohol, it takes energy to melt the ice, and the energy comes from the liquid, in the form of heat, which, in turn, lowers the temperature of the...

    What decides the colour of light?

    Are you saying that it's more proper to note that we are seeing red at 400–484 THz rather than seeing at 620–750 nm. I know these are equivalent, but in terms of perceived color we are responding to frequency?
