The PhD is a doctoral degree, specifically called a "doctor of philosophy" degree. This is misleading because PhD holders are not necessarily philosophers (unless they earned their degree in philosophy!). That said, PhD recipients are able to engage in thought experiments, reason about problems, and solve problems in sophisticated ways.
Estonia is among other things known for its forests (they make up almost half of the territory) and for being the only country in Europe with almost total 4G network coverage. Estonia provides high-level and internationally recognized education, and many universities in the country offer degree programs in English.
