Strong AI Is A Theoretical Impossibility

Posted by in categories: materials, robotics/AI

Thesis:

Part I: It has been proven that the human mind cannot be analogous to an electronic (or any other type of) computer, and the functioning of an intellective mind cannot be reproduced (though it can certainly be simulated) by any type of mechanical device, including modern artificial intelligence systems.

Part II: It is further impossible that the human mind is a purely material thing (including some “emergent property” of matter).

Atomic-scale semiconductor process technology and clean hydrogen technology join hands

Posted by in categories: engineering, materials

To enhance this efficiency, there is a requirement to fabricate electrodes with a . Unfortunately, existing technologies face challenges in achieving a uniform coating of ceramic materials within electrodes possessing intricate porous structures.

A collaborative research team, comprising Professor Jihwan An and Ph.D. candidate Sung Eun Jo from the Department of Mechanical Engineering at Pohang University of Science and Technology (POSTECH), and others, has successfully produced porous electrodes for SOFCs using latest semiconductor processes. This research has been featured as a back cover article in Small Methods.

The process of atomic layer deposition (ALD) involves depositing gaseous materials onto a substrate surface in thin, uniform atomic layers. In a recent study, Professor Jihwan An’s team, known for their prior work in enhancing the efficiency of SOFCs using ALD, developed and applied a powder ALD process and equipment. This enabled them to precisely coat nano-thin films on fine powders.
