Messages - Testy Calibrate

Well you seemed to be pretty interested in one thing - Lake K - for quite a while.  And Testy was interested in one thing - dendrochronology.   How about let's return to the  specific example  of Lake K to illustrate what you are talking about?  Everybody says I'm scared of it but that's not true. I actually like it because it's specific. I hate generalities.
I wasn't "interested" in dendrochronology.  I told you I would debate you on any topic you wanted and you could pick my side to demonstrate that you are an idiot. You chose dendrochronology, thus making my point before we even started. You still don't seem to understand what I did in that debate. Which is fine. I actually did "do it for the lurkers, or, more specifically,  for Google indexing.

One question I have about Lake K is... Why are there only 9000 "varves"?   Why not 50,000 or 100,000 like in Lake Suigetsu?
To make idiots ask questions.

Trump on Erdogan, yesterday:

Quote
Thank you very much. It's a great honor and privilege -- because he's become a friend of mine -- to introduce President Erdo─čan of Turkey. He's running a very difficult part of the world. He's involved very, very strongly and, frankly, he's getting very high marks. And he's also been working with the United States.

We have a great friendship as countries. I think we're, right now, as close as we have ever been. And a lot of that has to do with the personal relationship.

No, this is not a parody. It comes straight from the White House:

And today, Erdogan protesters were beaten and ejected from his New York speech, again:

It may not be the future they want but it's the future they need.

It's weird how sometimes what used to appear corny suddenly appears disturbing. It's well done though imo.

But it might not matter:

What comments is he referring to?

Don't know where this goes but I am fucking around on Twitter and found this:

Ok, so how do you feel about Paul Ryan, Rand Paul, and Donny Trump's policy positions generally?

I'm agnostic regarding peer review.

You aren't a Republican by any chance are you?

A good link but is there some specific point you want to make?

Do you agree there isn't an opposing vector for a force acting on an inertial mass? Inertia is not a force so it doesn't rate a vector.
Maybe not a huge point to dwell on but the inertia tending to hold the cart in place while the belt is pulled under it is important for understanding how the cart can advance on the belt. Of course, it also needs propeller thrust to do that.
No I wasn't making any point. I just thought the article was apropos for this thread.  Anyway,  do you think that's how the blackbird worked? Slipping?

I don't believe the bb worked at all, at least not Directly downwind and the "evidence" certainly does not establish that.
Some folks you just can't please.

We'll, I think blackbird put the doubts to rest.

Or just film it with a high speed camera

You don't seem to realize that it is entirely possible to have the cart on a moving belt, hold a position with respect to the stationary ground, even in a vacuum! All you need to do is move the belt fast enough so that the wheels are losing traction and sliding while rolling on the belt.
Hahaha, what the fuck? The only way that would be true is if there is no friction at all between the belt and the wheels. Any friction whatsoever would make the cart move down the belt in that scenario. You have to be joking with this. There is no way you could possibly be that ignorant about basic physics.
Really? At least BD had the good sense to act as if he didn't even see what I wrote, or was blinded by cog dis.

You, on the other hand, respond as an idiot should.

So, do you believe the tablecloth trick will not work in a vacuum?

Do you even understand the question?

Do you understand that a tablecloth has more than zero friction?

Do you understand that INERTIA can overcome friction?

I doubt that you do!
Inertia can overcome friction? What does that even mean? How is it different from unequal opposing forces and straightforward vector analysis?

Why are you pretending not to understand this? See my reply just above.
Heh, from that quote:
Except, the tablecloth is "slippery," so the force of friction is small and the cloth slides out from underneath the objects without dragging them too much

So the opposite vector is small. Why are you pretending not to understand this?

The "opposite vector"?

How do you assign an opposite vector to INERTIA, when inertia is NOT a Force?


Really? That's your answer? Really? Gravity is a force, right?

Holy shit!

I thought you knew some physics, TC.

I will give you a chance to rethink that, only because we are friends.

Hint: Gravity has NOTHING to do with Inertia.
No, but it has something to do with the vectors. Also, why would you think I knew something about physics?
Anyway, Newton's 2nd law is pretty straightforward.  F=ma. Inertia is derived from the motion. In this case, friction is the force that accelerated the mass and the time over which it is applied determines the total acceleration. Then there is a more complicated issue of friction the other way but not that complicated. It's still just straightforward vector analysis. It's definitely possible that I'm wrong and just making up physicsy sounding words though.

No, it has nothing to do with the "vectors". In the case of a force moving an object where the force is opposed only by inertia, you only need one vector, although you could draw more if you like.

Hmm.

Pingu ...  you are getting better about saying things more simply but this last post is still too complicated.  Try to explain it like you were explaining it to a third grader.  I don't understand why we would not expect all the curves to agree under EITHER model.  Why would that be exclusive to the OE model?
Well that was a bit of a surprise.

I was totally expecting "It's a conspirasee!!"

But Dave, so far Pingu has described data and analysis, independent of any assumptions, expectations, or even 'models'. It's. Just. Data.
I wish you were right about that. If scientists would just talk about "data" separately from their interpretation of that data and keep the distinction clear, we would be far better off.  But unfortunately they say things like "Sloth dung of unit a was deposited between 13,000 and 11,000 years ago at a rate of approximately blah blah blah" ...  they just casually state that as if it were a fact.  But it's not. And it's not data. It's their interpretation of data.

Interestingly, Dave, that was the very point I was making earlier, but you rather brushed me off.  As I tried to say then, "fact" is a somewhat informal term in science.  More accurately, we have DATA and we have MODELS that fit that DATA.  And DATA at one level of analysis is a MODEL at a lower level. So to an archaeologist, the radiocarbon date of a sample is DATA, from which she constructs a MODEL of how she thinks that society lived, e.g. hunter gatherer, whatever.  But to a mass spectroscopy lab the DATA is the measured C14:C12 ratio in the sample and the MODEL is the equation that returns a date from that DATA.  Further down still the C14:C12 ratio in the sample is ALSO a kind of model just as an average is a model.

It's quite important, if a bit geeky.  But to avoid papers being written entirely in Reverse Swahili Pig Latin, scientists take shortcuts, and treat as DATA "what they are given" - which is literally what it means, and what in this case they receive from the lab.  We can always go back and query the model that generated that DATA.  But DATA really does mean "What we are given".  It does NOT mean "FACT".  Although it seems reasonable to regard "these are the numbers we were given by the lab" as a fact.
OK I'll buy that.

What that means is that all models are wrong. Including yours. Science is accepting that fact about models. Belief is the destroyer of minds is just as true of any strong belief in any narrative, be it scientifically derived or religiously.

No, I don't think I am an insane cop.

I do think MZ may have been 'blocked' that is, had a spell cast against him that returns 'witch'.
For scum to kill confirmed special Diva and blocked Town MZ cause he leads town makes all too much sense. :(

But we now have four final votes against MZ, so that is the way the chips have fallen.
Well played scum if so.
Hmm. To pick mz out of yesterday's game seems more random than well played. What kind of block affects the seer's view? Would it require knowing who was going to be viewed? Or would it have required guessing who the cop was? From yesterday's game I could imagine guessing you were a cop but not that you'd view mz.

Mafia / Re: Witches Day 2
If tw is insane cop, we must have a real cop which means tomorrow morning we will either have two confirmed town or on plus the final scum. With an insane cop there'd seem to be only 3 scum.

Mafia / Re: Witches Day 2
Well,  we don't have much choice but to lynch you. Anyway,  ksen and teeth and Rach are in my scummy pile but teeth is on top.

Mafia / Re: Witches Day 2
A 12 person game with a Don probably only has 3 scum. We had a doc, a day vig and a cop. Unlikely there are any more specials. With a day one like we had and a good view last night,  I think day 1 votes should be enough to figure out the 3rd witch. If there's a 4th witch, then we'd have another special. So, if a town special gets night killed or lynched, then we need to be looking for teamwork clues but as it is, I think mz goes down and teeth is the final scum.

Well,  you seem to have done pretty well in this one.
