Emily, Humans and animals with eyes are pretty good at quickly identifying things seen in the past. It is a basic survival skill. “Identify the person”, “Identify the weapon”, “Identify the ripe fruit”. So when training populations for basic survival, you probably have to go back to “Identify and classify quickly” – if you value

I want to read lines from the scanner – without actually scanning. I want to read the data from the CIS sensor (not camera based, but line based). It is for a scientific experiment related to noise in image sensors. So I don’t need to scan images, just read line after line – for days

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,

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

Donna Kutac Janak My air conditioner is really inefficient so I keep it at high temperature setting and run two fans continuously. The cost is half of running the air conditioner alone – and more comfortable. I enjoy the noise. You should be asking people why they would run their air conditioner “without” a fan!?

Comment on YouTube Jason, I watched this Genius of 3D Printed Rockets video the other day. They are using plasma discharge heating, but it is not very well controlled at all. They say “it works really precisely”, but it throws off heat and light and bits of wire, and fluctuates a lot. It only needs

Jean, I want to find a contact image sensor CIS that has high dots per inch, large color depth (bits per pixel color) and fast speed (lines per second). I need three of them, and don’t know where to buy the parts. I just started looking and found that the mobile document scanners (Brother) seem

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

Cream Cheese, Jalapenos and the future of the human species I am trying to reduce my use of butter, so rather than making toast with butter I used cream cheese today. Since I am curious about the health value of foods as a topic on the Internet, I decided to add diced jalapenos. Then, because

A wave traveling between two parabolic antennas https://www.youtube.com/watch?v=v0cZjOIfwos You might try receiver-transmitter pairs, where each inverts the signal to build a standing wave. Use the final state inside the volume (arbitrary and time dependent if you want) as the constraint, then solve for the signal modifications needed at each site. I first saw this more
