Beginnings of geophysics at VŠB
Müller, Karel
Development of geophysics at VŠB in Příbram and Ostrava was connected with the names of prof. F.Čechura and ass.prof. R.Běhounek. The first magnetic measurement for geological purposes was carried out in 1928. The lectures on applied geophysics became a part of teaching of mining engineers and, afterwards, geologists as well.
