Ponderables
Ponderabilien ( Latin ponderabilis - weighable) is an educational, rather outdated expression for tangible, calculable things ( weighability ). The term is only used in the plural; the opposite are imponderables . Both terms probably go back to Antoine Laurent de Lavoisier , who thereby distinguished elementary substances that cannot be weighed (e.g. light substance ) from the weighable basic components of gases .
