Rochowa monografija je uvod v elektrokemijo, namreč v reakcije, ki prenesejo elektrone (oksidacije, redukcije in jedrsko sevanje), in naprave, ki shranijo elektriko (baterije in akumulatorji). Čeprav jo je napisal pred petdesetimi leti, je tema dandanes še aktualnejša, saj je skrajni čas, da presedlamo s kurjenja organskih snovi (premoga, nafte) na ekološko prijaznejše vire, kot so sončna, kinetična (veter, plima) in geotermalna energija. Pri teh pa potrebujemo ekonomičnejše akumulatorje. Celo jedrska energija je dandanes slabo izkoriščena: vso energijo najprej pretvorimo v toploto in jo nato speljemo skozi običajni toplotni stroj. Kakšna škoda, kajti jedrska energija je prosta energija, ...

A summary of investigations (1962-2022) into the origin and nature of existence. For those interested in the fundamental logic that drives physics … the universe, conjectured to be the embodiment of logic rather than its subject, is forced from nothing, step by step, uniquely, as the geometric embodiment of a simple integer count ... along with all major aspects of physics and cosmology … inclusive of quantifying the four forces and describing their active cause in geometry. Additional topics considered: consciousness, psychology, philosophy, theology, religion, government, economics, work, business, education, language, music, art, geo-sciences, interstellar propulsion, megalithic eng ...

From the Landplane Preface > ...this Guide attempts to present the essentials of safe and technically sound flight testing to the E-AB pilot community in a practical, easy to understand way. The flight test topics deemed important to E-AB flight testing derive directly from NTSB recommendations and latest FAA guidance. They represent a mixture of test philosophy and how-to-do-it flight test techniques subjects with an overall emphasis on best practices and safe test conduct. From the Landplane and Seaplane Preface > … there are differences in test procedures between landplanes and seaplanes and they deal with their ground and water handling regardless of whether or not the airplanes ...

This flight test guide presents the essentials of safe and technically sound flight testing to the amateur-builder pilot community in a practical, easy to understand way. The flight test topics deemed important to amateur-builder flight testing derive directly from NTSB recommendations and latest FAA guidance. They represent a mixture of test philosophy and “how to do it” flight test techniques subjects with an overall emphasis on best practices and safe test conduct.

The anode to cathode distance of a Hall cell is an important parameter to understand and control. If it is excessively large energy is wasted. If it is too small current efficiency is reduced. If smaller yet, the cell will become unstable. The anode to cathode distance is adjusted by moving the anode bridge to control cell resistance. It is generally assumed in resistance calculations that the bottom of the anodes are in one plane. It is also generally assumed that the cathode surface, which is the liquid metal, is static. Thus the anode to cathode distance is generally assumed to be the distance between the two parallel planes. In this paper, a simple and accurate method will be des ...

Power input to a cell is the product of volts and current and is therefore two dimensional. In this paper, we will use two dimensional charts to visually illustrate the power input to a cell used to make aluminum and the power used to maintain the cells heat balance. In doing so, we will also explore the power efficiency of the cell as well as defining other related efficiencies.

How do we make learning fun at school AND at home? Engage children in the process of discovery.  This is the reason why we advocate for things like reflection and questioning ---because it prompts our curiosity and pushes us to want to discover what we don't know. There should be a time where children can ponder on their own questions and do their own digging.
