It subsequently developed into the largest research center worldwide as a place where scientists could concentrate exclusively on their research subject, and served as a model for similar institutes established in other countries.Within a very short time, the PTR produced extremely important scientific results that cemented its international position at the top, such as Max Planck's radiation law and energy q 606 $aPhysical laboratories$zGermany$zBerlin$xHistory 606 $aPhysics$xResearch$zGermany$zBerlin$xHistory 615 0$aPhysical laboratories$xHistory. 615 0$aPhysics$xResearch$xHistory. 676 $a530.0943 700 $aHuebener$b R.
