esldude Posted February 11, 2016 Share Posted February 11, 2016 They did have to use vacuum tubes. And while the discovery is interesting I want to hear more about the wire they're using to carry signals and data. And always keep in mind: Cognitive biases, like seeing optical illusions are a sign of a normally functioning brain. We all have them, it’s nothing to be ashamed about, but it is something that affects our objective evaluation of reality. Link to comment

esldude Posted February 11, 2016 Share Posted February 11, 2016 I 'm sure Synergistic Research is already working on it. My initial thought was Synergistic Research probably already had this it was just proprietary. Second thought was no one close to those endpoints had one of the SR Atmosphere thingies in operation. It would have damped out the signal I am guessing. But hey, maybe they used all SR cabling in the experiment.

Rock Bottom Posted February 12, 2016 Share Posted February 12, 2016 I guess it is only a matter of time before the first gravitational wave isolation products show up! I have been reading about this all morning, Fascinating, as Spock said! OT - James45974 I notice the Rietveld chair photo. A part-time design instructor of mine in college in late 70's asked me if I could repair two broken chairs - I was making furniture at the time. When I went to fetch them I was pleasantly surprised, they were both very old Rietveld zigzag chairs. And both in bad shape, the glued planks having separated down the length of each. I was well aware of this chair design so I was curious and asked about these. Seeing my excitement she then showed me a cabinet maker's stamp on each and then went on to explain that they were part of the final prototype run for Rietveld himself! I was shocked. She then reminds me her last name is Schroder, as in her mother was Truus Schroder, design confidant and Rietveld's final domestic partner in life. Yep, the part-time Uni instructor teaching design studio drawing technique grew up in the Rietveld Schroder House - arguably his most important work.

But as a plot point in a movie it is simply ludicrous (that McConaughey's view of space-time probabilities/possibilities from a spatial location orbiting Saturn consists of iterations of the back of a bookcase in a room of his home on Earth decades in the past, with the back of the bookcase and the wall it sits against conveniently not included in this higher dimension, so all he has to do is give the right books a good shove off the shelf and wait for his daughter standing in the room on Earth to figure out the poltergeist is actually her long lost dad and what he's trying to say).

I was in the Netherlands in the mid 80's, never made it to Utrecht. I was traveling with other people and couldn't make the whole trip about architecture! I have always wondered about the structural integrity of the zig zag chair! Don't know if it could support some of today's physiques! Back on topic, I have been reading about this discovery but have not yet seen any info on how fast the gravitational waves travel, I assume it is the speed of light? Also, how do they know where the waves come from, it seems like they are being very specific about the source and I wonder how that was accomplished. Jim Link to comment

james45974 Posted February 12, 2016 Share Posted February 12, 2016 The Real Meaning of Einstein's Gravitational Waves - The Atlantic Thanks Paul, the article had a nice explanation for my question. I grew up reading this kind of stuff, my father, a Marine in WWII in the south Pacific, never went to college, worked as a machinist at GE, must have been a scientist in a former life because the house was full of magazines with similar kinds of articles. Didn't matter if it was astronomy, biology, geology, etc, it all interested him. We had books by Darwin, Audubon, Luther Burbank, and more, a rather big library. I gave him a copy of Hawking's "A Brief History of Time" for Christmas one year and he devoured it. He had music in his life too, he was a fan of opera! And he was a pretty decent chess player!
