Thanks, 'j'. You got the point of this discovery. It jumped out at me in the same way. The report makes the point that the covering of the shell would have probably been green so the marking down into the white shell underneath would have made the scoring stand out. If it had only been one scratch then it would be called an incidental mark, but it went well beyond that to be a deliberate pattern.
Frankly, I am still confused as to why it's not (more simply) "circular polarisation" that has been known about since the early days of radio.
True! "This call may be recorded..." is a bi-directional statement. I love the logic.
Also, if in doubt, as you hear the 'statement', repeat their exact words into the phone.
And, if in further doubt, when a real human comes on the line, ask, "Do you agree?" If the answer is a spluttering 'Yes' then.... or if 'No' then say "Please review your recording of his call, and I'll wait on the line as you do that." And, listen to what happens; It's likely to be hilarious!
"Only about one in 100 trillion proton-proton collisions would produce one of these events," said Marc-André Pleier, a physicist at the U.S. Department of Energy's Brookhaven National Laboratory who played a leadership role in the analysis of this result for the ATLAS collaboration. "You need to observe many [collisions] to see if the production rate is above or on par with predictions," Pleier said. "We looked through billions of proton-proton collisions produced at the LHC for a signature of these events—decay products that allow us to infer like Sherlock Holmes what happened in the event."
The analysis efforts started two years ago and were carried out in particular by groups from Brookhaven, Lawrence Berkeley National Laboratory, University of Michigan, and Technische Universität Dresden, Germany."
It is a dark room and I do not touch-type.
I do not presume that the satellits has been the other ageny of the USA government.
:-) I've been there, too. My first computer was an IBM 1130, with 8kB of 'ram'. From what I can tell, here, we have 0kB and all hard-wired to the devices attached to the receivers and transmitters. The satellite just 'talks' via the transmitter and Earth has to listen, or lose the data. That is "how it was" in 1978 (earlier for the finalisation of the design, and the satellite's set-up of the NSA Deep Space Network ground stations).
