The Franks

None of the German peoples of whom we have so far spoken, except the Franks, ever succeeded in establishing a permanent kingdom. Their states were overthrown in turn by some other German nation, by the Eastern Empire, or, in the case of the West-Gothic kingdom in Spain, by the Mohammedans. The Franks, to whom we must now turn, were destined not only to conquer most of the other German tribes but even to extend their boundaries into districts inhabited by the Slavs. Continue reading “The Franks” →

Miracles and Spiritual Experiences: the Power of God or Products of the Brain?

by Mr. Manolis Karakostas

Over the course of the centuries there have been many who’ve sought some kind of sign, a miracle, either to convince them to believe in God or to strengthen their existing faith. This is certainly still true today: we want to confirm God’s existence and think we can do so if another world is revealed through the senses via a miracle or some other spiritual experience. The revelation of this other world would bring us to certain faith in God*. Of course, in the Orthodox Church, this is not the way we discover God and are united to Him.

Bioengineers create ultrasmall, light-activated electrode for neural stimulation

Neural stimulation is a developing technology that has beneficial therapeutic effects in neurological disorders, such as Parkinson’s disease. While many advancements have been made, the implanted devices deteriorate over time and cause scarring in neural tissue. In a recently published paper, the University of Pittsburgh’s Takashi D. Y. Kozai detailed a less invasive method of stimulation that would use an untethered ultrasmall electrode activated by light, a technique that may mitigate damage done by current methods.

High-performance quantum dot mode-locked laser on silicon

Ten years into the future. That’s about how far UC Santa Barbara electrical and computer engineering professor John Bowers and his research team are reaching with the recent development of their mode-locked quantum dot lasers on silicon. It’s technology that not only can massively increase the data transmission capacity of data centers, telecommunications companies and network hardware products to come, but do so with high stability, low noise and the energy efficiency of silicon photonics.
