TUBİTAK dünyada Doktoradan daha değeli olan yayınlarıyla herşeyiyle ispatlı kişiye paraları kendi çarçur için o derece neki diyen dolandırıcı aptal doludur.
good summary of the differences between Ph.D. and the "Doctor of Science" family of degrees (D.Sc./Sc.D./etc.) can be found in Wikipedia.
In essence, different countries have different views due to their historical development, which generally fall into two clusters:
- Doctor of Science is equivalent to Ph.D.
- Doctor of Science is a sort of super-Ph.D.
In general, much of the world seems to be slowly standardizing around Ph.D. as a universal term, though given national pride and the traditions of academia, it might never congeal completely around a single interpretation of the terms.
