Generating synthetic gravitational fields

Teri, I was doing a quick study on “color from structure” and related concepts.  The colors of butterfly wings are often not pigments in the traditional sense, but emergent colors because of the shapes of the molecules. What clicked in my mind is that the sub wavelength structures (the structures that produce the rather large

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

Comment on Jordan Sullivan, Neutrinos and Antimatter Video

Neutrinos and antimatter at https://www.youtube.com/watch?v=YcpNhPBxwfo Jordan, You can combine a particle and its anti-particle into a stable form, if you provide angular momentum. The external charge and magnetic dipole moments are effectively zero, and the particle is effectively all binding energy which has no mass. The pair can store most any amount of energy, but

Comment on changing torsion bars to controlled shock absorbers – value of measurement and simulations

I Deleted My Tahoe’s Torsion Bars for Something Much Better at https://www.youtube.com/watch?v=fOyuvd5epFg There are apps for your cell phone that record the data from the three axis accelerometer. So you can change the settings and run on a given road at different settings to see the change in the impulse response of the car to road

Comment on Cat and Plasma Ball, Rotating Plasma Ball, Plasma Ball and Fluorscent tubes and bulbs, iPhone

Cat and Plasma Balls at https://www.youtube.com/watch?v=XkJYY4dDdr0 The cat investigated all parts of the globe, power (it can smell the hands of the person on the plug most likely), and behavior (optical, response to touch and nearness, acoustic because its ears and nose can pick up more than our fat fingers) methodically. Its nose is rather

Groups sharing models and data on the Internet, not paper – the case of “neutrino” OR “neutrinos”

Maury, Please post your Long Baseline Neutrino Newsletters on the Internet, and only send links and short announcements by email.  Make a member site and let people control their email notices. I think I wrote about this before, but is this newsletter available online somewhere.  My email only has a fixed part of the screen

Comment on video about the solar interior – another way, with the whole human species working together

What Does The Inside Of The Sun Look Like? https://www.youtube.com/watch?v=8ayHXTnN4fk In the visualization from 3:00 to 4:00, I think there should be small particles coming from every point to every point in the detector. For instance something coming from the far upper right. to the far lower left. Not just radially outward from one point

Contact Imaging Sensors, Linear CCD arrays for gravitational and magnetic imaging

Jean, I was trying at least two pathways: 1. Build circuits to read the analog signals from these linear sensors, and put the fastest and best ADCs to read and store the data. The focus on high precision measurement of the signals as a function of reference voltage. 2. Somehow learn to talk to these

Comment on exploding cell phone batteries

My cell phone popped open when I was talking. The reason is the battery had expanded to three times its normal size. I searched the Internet and found this is called “swollen battery” and found some videos of cell phones exploding and burning when the swollen lithium battery is punctured or compressed. My question: Is
