Is there a way to ask for help? I have many projects that I would like to try, but often am missing critical pieces that probably are obvious or trivial for someone else. For instance, I want to write algorithms for pan tilt zoom imaging with multiple cameras. The algorithms are relatively easy – but

https://www.facebook.com/groups/172438633343696/permalink/877591389495080/ I am looking at daytime uses of all sky cameras. Satellite images are a bit too bulky and not enough resolution for correlations. Need multiple cameras to recover 3D of clouds. I have seen groups aiming at comets, planes, clouds, rain, sky color, daytime astronomy (is possible), sun and moon tracking, shadows, reflections, multispectral,

Robin, Haje, I am looking at global sensor networks, and got to magnetotelluric arrays. For background I was reading about natural signals that can be used for calibration and reference and came to http://ampere.jhuapl.edu/index.html To be explicit, I was at https://en.wikipedia.org/wiki/Birkeland_current and clicked on the link to Project Ampere that took me to https://web.archive.org/web/20050211120508/http://dysprosium.jhuapl.edu/ Then

Orion Nebula WITHOUT a Star Tracker or Telescope, Start to Finish, DSLR Astrophotography https://www.youtube.com/watch?v=iuMZG-SyDCU I am trying to estimate the time and cost for myself. Today is 19 Jun 2021 for me. Amazon link to Canon EOS 5D Mark III body only is $899.99 + shipping and tax – never used Canon, lots of screens

https://www.researchgate.net/post/Is_there_any_paper_scientific_document_that_shows_how_much_mA_is_typically_considered_as_the_input_current_in_the_ERT_and_IP_fields2 Mostafa Ebrahimi, When you ask questions like this, spell out what all the acronyms. IP is mostly “intellectual property” or other things on the Internet. “electrical resistivity tomography” “induced polarization” gives 42,100 entries on Google search. That means it is fairly mature. If you are actively surveying a large region you might

https://www.researchgate.net/post/Please_I_want_to_enquire_How_can_I_download_Geomagnetically_induced_current_data_GIC_of_one_minute_time_resolution_data Alaa Mohamed, Today I was just reviewing “global conductivity models” and “geomagnetically induced currents” for the Internet Foundation. The common practice seems to be to use 1D and 3D conductivity models, then use the fairly dense magnetotelluric (MT) arrays for the changing magnetic fields that induce the changes. There are LOTS of electromagnetic datasets.

£700 vs £7,000,000: Astrophotography Shoot Out https://www.youtube.com/watch?v=4rCyC3_YIME Ryan Fay? Your link in the description is broken (luckyimage) should probably be https://www.astrobiscuit.com/deepspaceluckyimaging There are better ways to combine images from many different sensors. You talked about hundreds?, thousands?, millions?, billions? of people combining images to improve earth surface imaging. Take the human out of the loop.

L.D. Edmonds I did not mean to stir things up. I track global sensor networks (the communities of people working together) and many of the “quantum” and “gravitational” and “quark gluon” and “neutrino” groups get rather esoteric in their language and methods. The methods are not too hard, but sorting out what people mean by

https://www.researchgate.net/post/Was_Schrodingers_equation_born_from_statistics The Schrodinger equation, as it is used most of the time, is the 3D wave equations with stationary solutions. In every practical application you use dynamic models where the resonances and states are part of the constraints. The vacuum states usually require working with the nonlinear Schrodinger solutions. And most scattering and resonance problems

Strings are just one example of the larger problem of sequences and patterns (any dimensions). This morning, I am just surveying the Internet for rock types and measurements used in geochemistry. There are many methods and representations. Does the student like to explore, to gather, to find general patterns, to share what they have found,
