When I was at the University of Maryland at College Park in the late 1970’s I met Joe Weber and Charles Misner and others who were starting gravitational wave detection. So I have followed it over the years. I think it very unlikely that aliens would be using the very narrow band of electromagnetic signals

Karen Lee-Waddell, Pete Wheeler, SKA web contact, I am trying to piece together the Internet data sharing policy for SKA from what is visible on the Internet. Is SKA data going to be available to everyone on the Internet? In accessible form? Reading these it seems SKA data is only for certain people for very

Earthquake seismograph using bismuth magnetic levitator as sensor at https://www.youtube.com/watch?v=aIANNzpec7Y Tomislav Stimac, The “standard” still for accelerometers is the small but global network of super conducting gravimeters (SGs). They use liquid helium cooled niobium magnetically levitated spheres as the test mass. The sensitivity is about 0.1 nanometers per second squared (nm/s2) at 1 sample per second.

What YOU Can SEE Through a $1 Billion, $32,000 and an $800 Telescope! https://www.youtube.com/watch?v=VwoII9TQd8k There are many countries with LOTS of people where $800 is more than the median annual income. And many more countries and many more people where $800 is more than monthly income. So here you are, posting a video that could

How to demonstrate convection at https://www.youtube.com/watch?v=-8PoCwx2de0 The simple materials are good, but you, yourself, did not explain what you were expecting, where the students and demonstrators were supposed to focus their attention. You said (don’t use purple shirt) and for this short video, why did you not go change your shirt and record it again? Or,

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

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

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

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

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
