Hayatta en hakiki mürşit ilimdir!
Ilim ve fennin dışında yol gösterici aramak dalgınlıktır, bilgisizliktir, doğru yoldan sapmaktır! Yalnız,
ilim ve fennin yaşadığımız her dakikadaki gelişimini kavramak, ilerlemeleri zamanında izlemek şarttır.


Science is the most committed guide to success!
Searching for another guide is ignorance and absence of mind. Understanding the development of
science and observing contemporary improvements are essential.
