Magnetic field of 1 Tesla

https://www.researchgate.net/post/How-do-i-produce-a-magnetic-field-of-1-Tesla-for-magnetoelectric-measurements David Coathup   Did you ever get your magnet working? I am writing notes on magnetic calculations and your 1 Tesla magnet is a good problem. This morning I found a good example in “Electromagnetics” by John D Kraus and Keith R Carver, 2nd Edition 1973, page 250. They cover magnetization in the previous

Suggestion to eLifeScience.com for email alert, online search, navigating their database of bibliographic data

https://elifesciences.org/contact Can I get lists of bibliographies and email alerts in machine and human readable format? Reading html is tedious and your people never pick display formats that are easy for me to read. I have to deal with all formats and data and knowledge in the Internet. The usual ones like xml and html

Pet peeves – Wikipedia, sites, videos, classes, universities, schools – talking about things that could easily be shared for real

Samuel, I hesitate to reply to many of your comments because in Videos 3-7, I cover a lot of issues and resolve them. I am not even sure what still remains to be done. All I can suggest is you keep a log of your specific people where they might need a deeper look. If

Musing about a video of a beautiful scene in Colorado

Richard K Collins That place call for a live 4K stream on YouTube. I found more than a thousand such 24/7 videos. Besides scenery, vistas, activity and seasons. During the day, clouds, animals, and weather. During the night stars, planets, moon, comets, satellites, more weather. With links it becomes a vivid advertisement. With links to

Comment on question about effectiveness of conferences – human and online

https://www.researchgate.net/post/Which_are_the_basic_criteria_on_evaluating_scientific_conferences_online_and_in-person? As Director, The Internet Foundation, I might recommend to never meet in person. Not only for covid, but also travel time, hotel and meeting costs, travel costs, inefficient use of time. Lots of reasons, mostly financial and efficiency related.   You are lumping too many things together with “conferences”. If it is to see

Self reproducing robot societies that live in the desert and convert sunlight to cities

I have had deserts on my mind a lot over the last few decades.  All during the 1980’s I worked on populations forecasts and issues in Africa, then the Famine Early Warning Systems (FEWS.net), then global climate change.  I sort of keep up with any efforts to turn those vast areas into something more suitable

Comment on Video Demonstrating Convection, and approaches to understanding and visualizing

How to demonstrate convection at https://www.youtube.com/watch?v=-8PoCwx2de0 The simple materials are good, but you, yourself, did not explain what you were expecting, where the students and demonstrators were supposed to focus their attention. You said (don’t use purple shirt) and for this short video, why did you not go change your shirt and record it again? Or,

Comment on old style MIT lab presentations. They are SO slow

Optics: Fringe contrast – path difference | MIT Video Demonstrations in Lasers and Optics https://www.youtube.com/watch?v=IZGnYe7BUms This is like those old serials – always ends with a cliff hanger. How irritating. Some good stuff, glad to see it. But wish he would not be so Socratic, and more measurement and data oriented. But this is a

Comment on Making Petrified Lightning – application to solar system colonization, global needs and new industries

TheBackyardScientist,  Making Petrified Lightning …with electricity? at https://www.youtube.com/watch?v=m7YznIKe7bU 3D printing metal. You can use metal or glass powders, control the current, and randomly choose next points – probably run on Arduino. You have all the skills and stuff mostly. Maybe someone already suggested. You might invent a way for YouTube viewers to work together, combine
