En yüksek iyinin ne olduğu sorusu, Sokrates ve halefleri Platon Aristoteles’e kadar uzanan kadim bir tartışmaya işaret eder. Fârâbî de başta siyasete ilişkin olanlar gelmek üzere çoğu eserinde bu temel sorunu irdelemiştir. İnsan için en yüce hem dünyada öteki gerçek mutluluğa ulaşmak olduğuna etmiştir. Gerçek ancak hakiki felsefeyle, iyiliğin güzelliğin kaynağı olan Tanrı’yı bilmekle erdeme uyg...

It is proposed that the highest energy ∼ 10 20 eV cosmic ray primaries are protons, decay products of a long-lived progenitor whose high kinetic energy arises from decay of a distant (cosmological) superheavy particle, G. Such a scenario can occur in e.g. SU (15) grand unification and in some preon models, but is more generic; if true, these unusual cosmic rays provide a window into new physics...

Ever since the discovery of virus in beginning of 20th century, infections caused by these organisms have captured attention of researchers. The evolution of viruses is still a controversy, even same for their categorization in either living or non-living. It is clear that besides many controversies virus remains challenging to treat as well as to control in some extent. Though vaccines are ava...

We review the current state and future prospect of ultra high energy cosmic ray physics and the relationship between cosmic rays and gamma-ray astrophysics.
