Aiiighhtt.... I have finally found an answer from somewhere.... and basically, Planck was just interested in pure science, he believed the application and consequences of research should be left to politicians and etc whereas Einstein took a moral stand and said that not all research is good research eg: atomic bomb which killed millions of people
More recent stuff has been the cloning/genetic engineering moral issues... pure research means to research these things without a worry in the world however it can have severe etchical consequences....
Another thing is that companies and governments are more likely to FUND research that is already sucessfull or back up some facts that they can use in their favour eg: phone companies funding research that finds there is no link between mobile phone radiation and cancer.... This can be at the expense of other research, it should be noted that some stuff was discovered by accident eg: Hertz and photo-electric effect and X-ray diffraction, if other avenues of research is not pursued we wouldn't benefit from "accidental discoveries"
That make any sense people???
