How light can be both a photon and a wave at the same time?	[ "Light is actually neither. It's something entirely different.

Why does a small amount of antenna extension in devices such as portable radios and satellite cellphones make such a big impact on quality of reception?

Why does not having an absolute zero (interval scale) mean ratios between intervals are meaningless?	[ "Think about room temperature.
