“Man braucht eine kritische Naturwissenschaft”

“This world is given to us on loan. We come and we go; and after a time we leave earth and air and water to others who come after us. My generation, or perhaps the one preceding mine, has been the first to engage, under the leadership of the exact sciences, in a destructive colonial warfare against nature. The future will curse us for it.”

Some of these conceptions do not correspond with the scientific view, for example the transfer of properties from the level of substances onto the level of particles. Many students fall back on their original conceptions outside the classroom. Examples of those daily‐life concepts and their development are presented here.
