Rand Paul's Grasp of the Constitution and Its Amendments
StringJunky replied to ydoaPs's topic in Politics
Reading that piece of the Constitution, which I think is lousily written should read: A well regulated Militia, being necessary to the security of a free State; the right of the people to keep and bear Arms shall not be infringed. It needed a semicolon. Or my way: A well-regulated militia, being necessary to the security of a free State, but the right of the people to keep and bear arms shall not be infringed. Both of my amendments mean the same thing. -
Rand Paul's Grasp of the Constitution and Its Amendments

"Hi" said Kettle. -
Ontological (What things are) discussions have taken place here several times over the years and the general response from physicists is that they study behaviour and the intrinsic nature of phenomena is not their domain. What I've come to realise is that it's not really possible to describe fundamental properties in a way that relates to our everyday experience. Quantitative measurements of a phenomena's parameters and how they relate is about the best you can do.

The more you look into it the more you realise that 'we' are as much the bacteria we host as our bodies. When you think of the Earth, you think of everything in it and on it, as well as its geology; that's what people are: mini-Earths. That's how I see it.

Can LIGO actually detect gravitational waves?
StringJunky replied to aramis720's topic in Relativity
They've discovered a new form of signal, how can that not be worth looking for? -

StringJunky replied to aramis720's topic in Relativity
They weren't looking for something new they were looking to confirm a prediction. We have learnt that, yet again, the old bugger was right. Because he was right this may open opportunities to explore further back in to the evolution of the universe, at least. You are, perhaps naively, trivialising this very difficult effort and its results. -

Which really need legislating for separately. -
Can LIGO actually detect gravitational waves?
StringJunky replied to aramis720's topic in Relativity
Well, people have been picking at GR for 102 years, so it's highly probable. -
Yes, it interests me. It's called the Gut-Brain Axis.

Can LIGO actually detect gravitational waves?
StringJunky replied to aramis720's topic in Relativity
There's TWO detectors 3000 miles apart and they've detected them SIX times (3 lots of two independent observations; as I mentioned before) and all those observations agree with GR. Tar. Unless one understands the maths of the theory and the techniques used for their observations one is not in a realistic position to critique this work in any meaningful way. The best you, and I, can do is try to understand what is given. -
The definitive reference.

StringJunky replied to aramis720's topic in Relativity
They actually detected them six times with two detectors; Three each. -
A legend in his own mind.

IIRC GWs might help scientists 'see' further back in time when the universe was opaque to photons.

The Americans make the most expensive valve amps, which can mega money. At the end of the day, if you like hi-fi, it's down the sound that moves and involves you in the music and for some people beyond a certain age, that'''s the 'valve sound'. The valve sound is closer to the 'live' sound of a concert, even with it's peculiarities. I think, technically speaking, because the current is always available, the transients are immediately produced with no delay or chopping... it's smoooooth. With records, snap-crackle-and-pop is part of the experience and, again, they sound more 'natural'' and immediate than digital media. Digital excels on dynamics and noise. Records are still selling well here and even the rock gods of the 70's are very much appreciated by the teens of today, judging by comments I read on Youtube. Analogue is just another flavour in the sonic palette.

Why do water drops leave marks on glass that won't come off easy?
StringJunky replied to Jmanm's topic in Applied Chemistry
When you do get the stains off, wipe the windows with warm water that has vinegar in it to stop residues in the future because it will soften the water. Distilled white vinegar is the purest. I use a good splosh of vinegar in half a bucket of hot water with a few drops of washing up liquid to clean my house windows; polishing is minimal after. If you want numbers and in a bottle: -
I think mine was about $4 for 1.8m with gold-plated connectors. The only time I would fuss about wire-type is with speaker cable which does make an audible difference,up to a point; as long as it's thick enough not to degrade the current which degrades the signal, I think. .I notice the loss in bass with thin cable anyway. I am pretty deaf, so the esoteric cables would be wasted on me but I can hear a difference between bell-wire and 49-strand QED. Do signals losses become noticable beyond a certain length with HDMI cable? Is DisplayPort the new top standard for digital connection quality?
