Nora, Thanks, I will keep that in mind. If you cast tiny angular (square, triangular, for example) blocks of plastic on ends of an optical fiber, then polish the whole thing, that would give a fiber that would alighn properly with a corresponding hole and fiber (or fibers). It is something that human hands could

Hello, Is there, somewhere, a profile of the Document Foundation community online? The “LibreOffice community”? The “Community Map” has no weights or sizes. I looked at the people and groups that you follow, and a bit of who they follow and are linked to. https://twitter.com/tdforg I attached my notes. The totals are not indicative of

Shawn, The atmospheric gravitational noise is much larger than the signals from the subsurface (usually). The noise in that gravimeter you want to buy is mostly atmospheric and thermal radiation field connected. Calibrate it against the sun and moon first. Then against 3D near realtime atmospheric models. (Climate and meteorology are just atmospheric, and the

Accelerometer Specifications: Deciphering an Accelerometer’s Datasheet by Steve Hanly https://blog.endaq.com/accelerometer-specifications-decoding-a-datasheet I see you mention temperature sensitivity. I am writing an article on gravimeters and recommending different ones. Someone estimated their response to temperature. It can be estimated for gravimeter arrays. Here is how I estimated it. Relation between gravity, magnetism and temperature at the earths

https://www.facebook.com/groups/AstronomyHouston Can you suggest a program to take two images from different cameras, combine and compare them? I am too tired to write more programs. Just wanted to look at some pictures I found on the web and see how the fit together. They are the same part of the sky, but different rotations, different

Shawn, I worked with the US Agency for International Development, the US State Department, World Bank and many international organizations. Most countries cannot afford to do their own mineral exploration, so outsiders come and take what they have. I helped put microcomputer training and technology into that system so that some countries could afford to

Windows USB GPS Device Based on UBlox Chip and UCenter Software https://www.youtube.com/watch?v=uJZHVKGrl6Y @Ali Zitouna Hamed, I am not sure what you mean by “base ntrip”. I made this long ago and have not used UBlox lately. Since then i have been working on software defined radios, electromagnetic interference, gravitational wave detection, imaging arrays for gravitational

Physics – RCL Circuits With Reactance and Impedance (1 of 2) https://www.youtube.com/watch?v=IVS-vjHdC1c I like your video. But I put the equations and data into a spreadsheet, and could play with scenarios quickly. This is an old video. I hope you are encouraging people to use computers to manage the equations and data. Teach them to

Alexander, https://www.youtube.com/watch?v=67eTLeNwLgE You are using what looks like to be a good computer tool for these calculations and visualizations. But you don’t explain your tools and give links to let others know what to use, or what you recommend. I watched your hysteresis video. It is really shaky and hard to watch. You could use

Intro to Fourier Optics and the 4F correlator https://www.youtube.com/watch?v=wcRB3TWIAXE Great presentation! My physics professor showed me this in the lab one day, more than 50 years ago now. He used black and white microfilm and microfiche. He showed me newspapers on microfiche that could be searched for specific things. Your clearer explanation of how to
