An Intuitive Approach to Cosmic Horizons

Operationalization of Formative Assessment in Writing: An Intuitive ‎Approach to the Development of an Instrument

The current study aimed to develop a Formative Assessment of Writing (FAoW) instrument through operationalizing Black and Wiliam’s (2009) Formative Assessment (FA) and Hattie and Timperley’s (2007) feedback model. Following intuitive approach of scale construction (Hase & Goldberg, 1967), a comprehensive review of the literature was undertaken, and 30 Likert scale items were devised.  The items...

On horizons and the cosmic landscape

Susskind claims in his recent book The Cosmic Landscape that evidence for the existence and nature of 'pocket universes' in a multiverse would be available via detailed study of the Cosmic Blackbody Background Radiation. I point out that apart from any other queries one might have about the chain of argument involved, this claim is invalid because it rests on a confusion between the nature of a...

The Expanding Horizons of Cosmic Life

The conceptual boundaries of life are rapidly expanding far beyond the confines of our planet to encompass an everwidening region of the universe. Complex organic molecules in interstellar dust and comets appear most plausibly to be biologically derived, or at least closely related spectroscopically and structurally to such material. A de novo origin of life from non-living material is reckoned...

An Intuitive Approach to Inertial Sensor Bias Estimation

A simple approach to gyro and accelerometer bias estimation is proposed. It does not involve Kalman filtering or similar formal techniques. Instead, it is based on physical intuition and exploits a duality between gimbaled and strapdown inertial systems. The estimation problem is decoupled into two separate stages. At the first stage, inertial system attitude errors are corrected by means of a ...
