Fall of Civilizations should be Changes of Civilizations – video comment

8. The Sumerians – Fall of the First Cities https://www.youtube.com/watch?v=d2lJUOv0hLA I would call it “Changes in Civilizations” and give a global context. Heard and saw many things I will try to remember. I especially appreciate the narrative on global climate change and sea level rise as a historical force. It made me wonder if the

Comment on a sunset image posted on Facebook – purpose, uses and sharing of live camera streams on the Internet

Peggy, I keep suggesting that you put in an all sky camera as a live feed to YouTube. I have been reviewing live videos like that on the Internet, and there are many of beaches, cities, mountains, forests, nature. I have found thousands of them and study them as a new Internet resource for education,

Particle Clicker Game at CERN

Hello, I was looking at all groups working on games on GitHub and came across this particle clicker game. http://particle-clicker.web.cern.ch and https://github.com/particle-clicker/particle-clicker “An addictive incremental game that teaches players the history of high energy particle physics” So you click, it pulls up a random diagram of a scattering event, with no associated data.  Shows it

The Internet is a mess. It encourages duplication, falsification, and excludes more than it includes.

Hi, Ann O’Keeffe. I am titling this “The Internet is a mess. It encourages duplication, falsification, and excludes more than it includes.” In the last 30 years I must have said to myself, a few million times, “Why are there so many topics where people all over the globe work on them, but never ALL

Astronomical Societies – Everyone has a right to see and study the sky, without begging or paying

Luis, I think the default should be – if I am looking at my settings – I want to change them.  I had to figure out that I first had to click on “Make Changes to Primary Member Record” (not a confirmation of changes, but getting permission to change it at all), which was after

Comment on Viki playback speeds, image controls, and search screens

I have reviewed the use of video playback speeds in various services.  YouTube uses 0.25, 0.5, 0.75, 1.0, 1.25, 1.5, 1.75, 2.0 but it is not sufficient.  I have experimented with speeds from 1/100 to 100x or faster.  Rather than a fixed set of speeds, an intelligent assistant can help. For action movies, they have

Trying to download frames from Solar Dynamics Observatory

Dean, Kevin, I am at https://sdo.gsfc.nasa.gov/data/aiahmi/# and wondering what the data looks like.  It says “Browser, Movie, Frames” but those are not formats, those are types.  A frame format might be PNG, FITS, SER or some other lossless format. You can make your URL for your names to be MailTo:dean_dot_pesnell@nasa_dot_gov so that it can be

Comment on The 49 dollar, 500 WattHour eBike Battery video

https://www.youtube.com/watch?v=0FwA_s9Ovxc You talk about motivations for watching and DIY at about minute 14. The reason I am watching is I have a lifetime of learning how things work, what they can do, and how to put them into different combinations. Often the off-the-shelf parts don’t fit, or are overkill or too expensive. Mostly they just

Comment on Video about laser interferometer design and use – replace superconducting gravimeters

Counting Atoms with the Doppler Effect – Heterodyne Interferometer by Sam Zeloof at http://sam.zeloof.xyz https://www.youtube.com/watch?v=vPu6lN9yJOY Sam, I sent you an email about using this to replace the network of superconducting gravimeters with something more people can afford. You have several orders of magnitude available to you by very small adjustments. SGs cost several hundred thousand and

Plans for measuring the speed of gravity again, using superconducting gravimeter and related sensor networks

One linear regression is all that is needed to useg JPL Ephemeris to separate the sun moon from earth-based signals I want to repeat the SG network speed of gravity measurement I did in 2003 using all the current stations. I will also use the best of the broadband seismometers from IRIS.edu. Any absolute measurements,
