I confess most of these were shockingly new to me, but it seems I'm a [strike]dumbass[/strike] follower of the late Mr. Scotus who figures into #8.

Now that the initial shock has subsided somewhat, my comments and questions:

1. saxophone - So shouldn't it be the Adolphone? (And is Adolphe's brother Goldman the on who founded the eponymous investment bank?)

2. nicotine - Makes sense that this is named after a Frenchman, that is also what is predicted by the branch of mathematics known as Galoises theory.

3. bloomers - And knickers are named after the famous NYC basketball franchise, yes?

4. mausoleum - I thought it was after the folks who made those "Corn - we call it maize" [url=http://www.youtube.com/watch?v=cuOlD0JZhM4"]cooking-oil and margarine TV commercials[/url], a kind of "bury my heart-clogging fats at Wounded Knee" ad theme. Shows you how much I know.

5. chauvinism - Another predictable "Of course ahm Fransh - why do you theenk I have thees outrrrrrrrrrageous acc-ent?" import. Note that the UK equivalent, jingoism, is confusingly named after a German, John Jacob Jingoheimerschmidt. I think it's a Hanoverian-dynastic thing.

6. Cyrillic - Ah, wrong again. (I had always thought "Cyrillic" was the Russian for "It's Greek to me, comrade").

7. lynching - I just hope this doesn't mean I'm gonna have to stop drinking Jack Daniel's out of moral principle. Please tell me the -burg is named after a different Lynch...

8. dunce cap - Speaking of lazy pupils, my ophthalmologist (derived from the name of Ophthalmus, a famous Greek seer who lived around 2500 BC) told me I have a case of those recently, but he prescribed eye exercises and some medicinal drops, pointy-cap-wearing didn't figure into it. Is he ripping me off by prescribing substandard care? If hat-wearing is an important part of the cure, I want to know.

9. fuchsia - Ah, I thought this was some kind of bizarre anti-honor for Klaus Fuchs, the (in)famous Manhattan Project leaker. So this means I can actually wear this color wihout being accused of being a crypto-commie? That would be cool.

10. Uzi - Yowzers. I though it was Hebrew for "Kalashniknov".

11. gardenia - Not your garden-variety eponym here. Oh wait...

12. braille - On the hearing-challenged side of the ledger, ASL is not an initialism for "American Sign Language" as commonly assumed, but rather is in honor of the late Turkish Dr. Aslan Canuhearmenowoglu, a famous 19th-century worker-with-deaf-children.

13. diesel - Not after Vin? C'mon, you're pulling mein Bein!

14. macadam - Wrong, wrong, wrong, it's because the stones in the mix look like the eponymous - and very expensive - nuts. Next they'll be telling us "tarmac" is short for "tar macadam". Pull the other one, guys!

15. bougainvillea - Not after the S. Pacific island? Dagnabbit, I really thought I had that one right, too.

Physics World called a weak measurement experiment [I]Breakthrough of the Year[/I] in 2011:
[URL="http://physicsworld.com/cws/article/news/2011/dec/16/physics-world-reveals-its-top-10-breakthroughs-for-2011"]Physics World reveals its top 10 breakthroughs for 2011[/URL][QUOTE]We have also awarded nine runners-up (see below). The choice between first and second place was particularly close this year because the number-two finding also involves weak measurement – this time to map the wavefunction of a bunch of photons. But we felt that Steinberg's finding edged it. Other breakthroughs in the list include the first "space–time" cloak, a laser made from a living cell and a new way to measure cosmic distances.

1st place: Shifting the morals of quantum measurement

Steinberg's work stood out because it challenges the widely held notion that quantum mechanics forbids us any knowledge of the paths taken by individual photons as they travel through two closely spaced slits to create an interference pattern.

This interference is exactly what one would expect if we think of light as an electromagnetic wave. But quantum mechanics also allows us to think of the light as photons – although with the weird consequence that if we determine which slit individual photons travel through, then the interference pattern vanishes. By using weak measurements Steinberg and his team have been able to gain some information about the paths taken by the photons without destroying the pattern.
In the experiment, the double slit is replaced by a beamsplitter and a pair of optical fibres. A single photon strikes the beamsplitter and travels along either the right or the left fibre. After emerging from the closely spaced ends of the parallel fibres, it creates an interference pattern on a detector screen.

The weak measurement is performed by passing the emerging photons through a piece of calcite, which imparts a tiny rotation in the polarization of the photon. The amount of rotation depends on the direction of travel of the photon – in other words, its momentum. The photons are then "post-selected" according to where they strike the screen, which allows the researchers to determine the average direction of travel of photons that arrive there.
The experiment reveals, for example, that a photon detected on the right-hand side of the diffraction pattern is more likely to have emerged from the optical fibre on the right than from the optical fibre on the left. While this knowledge is not forbidden by quantum mechanics, Steinberg says that physicists have been taught that "asking where a photon is before it is detected is somehow immoral".

"Little by little, people are asking forbidden questions," says Steinberg, who adds that his team's experiment will "push [physicists] to change how they think about things".

2nd place: Measuring the wavefunction

Second place goes to another group that has asked a "forbidden question". Led by Jeff Lundeen at the National Research Council of Canada in Ottawa – a former colleague of Steinberg – a team has used weak measurement to map out the wavefunction of an ensemble of identical photons without actually destroying any of them. Quantum tomography, in contrast, maps out the wavefunction at the expense of destroying the state. As well as boosting our understanding of the fundamentals of quantum mechanics, the technique could prove useful in cases where tomography cannot be used.[/QUOTE]

I wonder what places like Nigeria and the northern reaches of Siberia look like on a methane map. In the first, oil exploiters are flaring off huge quantities of methane because it's not worth their trouble. Those flare zones are [U]really[/U] bright in night, visible light satellite photos. It seems pretty likely that a great deal of methane can escape unburned.

What I'd be looking for in Siberia is signs of methane plumes from thawing permafrost, or from methane clathrates in a warming ocean.

Indications that the examiner.com article is sensationalist rather than informative:

1. Lead photo (of Comet ISON) is completely unrelated to the asteroid.

2. Loose, non-quantitative wording, with fear-provoking phrases/questions:

"passing uncomfortably close",

"The big question is, how sure is NASA that asteroid 2014 UF56 is harmless?"
(By the time a passing asteroid has received its provisional designation -- 2014 UF56 in this case -- its orbit has almost certainly been well-enough observed to determine whether it will collide with Earth this time. However, whether it might collide on future passes will take more than just a few days of observations. Ask your Congresscritters to ensure adequate funding for that followup work.)

3. Just plain ol' false statements:

"considering this object has only been known of for a few days, it's possible there hasn't been enough time to ensure it will pass safely"
(It takes only a few hours of observation to determine that an approaching rock will miss Earth. Basically, by the time almost anyone outside the professional community has even heard of it, its "safe" passage (or collision) will have been determined. There's a professional network of observatories that will swing their scopes to do the positional measurements (astrometry) on very short notice.)

"comet [URL="http://www.vice.com/read/siding-springs-comets-earth-at-risk-204"]Siding Spring[/URL] passing close to Mars last week (and causing a massive explosion in the planet's atmosphere)"
(No, Comet Siding Spring did _not_ cause a massive explosion in Mars's atmosphere. Only the sensationalist sites claim it did.)

"it was reported that the Australian observatory which originally discovered the comet is closing down. The closure leaves a gaping hole in the sky watch program, leaving the southern hemisphere largely unmonitored."
(No, there has been no report that Siding Spring Observatory is shutting down. Last year, a large bush fire threatened it for a few days, but no major damage occurred. However, there is a [URL="http://www.theguardian.com/science/2014/oct/21/siding-spring-observatory-threat-coal-seam-gas-light-pollution"]real [I]potential future threat[/I] that could force closing the observatory[/URL].)

"Comet Siding Spring passed within 90,000 miles of Mars, while this latest asteroid is reported as passing Earth at about twice that distance, or a little over 160,000 miles. That leaves open the possibility that asteroid 2014 UF56 could have a similar effect on Earth's atmosphere. It means this space rock doesn't even have to hit the Earth for it to do considerable damage."
(This claim just reveals the ignorance -- real or feigned -- of astronomy by the writer. The interaction between Comet Siding Spring and Mars was entirely due to gas and dust, emitted by the comet, that traveled many thousands of miles away from the comet nucleus. Asteroid 2014 UF56 is emitting no such stuff.)

[url=news.discovery.com/history/us-history/aluminum-fragment-appears-to-belong-to-earharts-plane-141028.htm]Amelia Earhart Plane Fragment Identified[/url]

Before anyone gets too excited: I have inserted in the Pacific Ocean section of an old world atlas a 20-year-old news clipping centered around a similar claim by the same outfit, The International Group for Historic Aircraft Recovery (TIGHAR), but featuring a different Pacific islet (Howland island). Apparently the business model here is one of every-few-years-trotted-out juicy claims about a "new discovery!" accompanied by requests for funding. An NC reader [url=http://www.nakedcapitalism.com/2014/10/links-103014.html#comment-2344735]explains the very dubious confirmation-biased approach used by TIGHAR[/url]:
[quote]Amelia Earhart’s life and final flight make for a compelling story. Sadly TIGHAR seems to be basically a fraud (unintentional or not). They have something of a bad reputation among the historical aircraft recovery and restoration community, have accomplished basically nothing, and use exceedingly poor methodology. The problems with TIGHAR are summed up in [url=http://skeptoid.com/episodes/4295]this takedown from skeptoid[/url]:
[i]
“Here’s the problem with TIGHAR’s findings. Even though they meticulously document and preserve every artifact, they exhaustively research each one to find matches with real objects from the 1930s, and they look exactly like what such an expedition should look like, their overall methodology is fundamentally, fatally unscientific. It’s unscientific in that it’s done completely backwards. TIGHAR begins with the assumption that Amelia Earhart crashed, camped out, and died on Nikumaroro. They take everything they find — every anomaly in a photograph or in a story, every piece of bone or manmade artifact found on the island — and try to match it to their assumption, rather than trying to objectively assess its origin.
[/i]
Nikumaroro, this tiny island where TIGHAR has recovered its artifacts, is in Kiribati, a nation of 100,000 people spread over millions of square kilometers of the South Pacific. People leaving artifacts come and go all the time.”

It makes me sad to see how every year or so (in time for a new round of fundraising), TIGHAR has “Found Earharts’ plane!” again and again and again.[/quote]

Nice, but alas safety concerns have made "Plan B" backup power generation options in the form of radioisotope generators a no-go.

Thus, we can only hope that they can revive the lander sometime next year when the comet is in a more favorable position w.r.to the sun.

The difference in CO2 values in that video from green to dark red is ~7ppm.

How big of an impact does an annual variation of 7ppm have on climate? The fluid dynamics in that model are beautiful.

Just to be clearer, imagine an [URL="http://en.wikipedia.org/wiki/Vital_capacity"]average person[/URL] going in a average room (say 5x4 meters big, and 2.5 meters high, which would give a 50k liters of air) holding his/her breath. Then he/she breaths-in deep, and breath out. Exactly 3 times. One, two, three. Then he/she goes out.

That is a change of about 7.2 ppm in the [URL="http://en.wikipedia.org/wiki/Breathing#Composition"]CO2 concentration in the room[/URL], like from the darker to the brighter on the chart.

I didn't see anybody dying around me after 3 breaths... Well, in spite of the farts in the room/office/etc...

Additionally, the chart is very biased due to the fact that the Earth is round, the northern and southern parts are ridiculously exaggerated, looking that half of the northern hemisphere is red. Look to a globe and see that Antarctica is not half of the southern hemisphere, but a "small spot" in the south. Same way, the big-red-north is just a spot around the polar circle.

But well, the animation is beautiful... :wink:

Side story: We have some sort of "food disorder". We are not sure if it is physical or mental or both, but it results in us being hungry all of the time. With intense exercise and ultra-restrictive diets, we have gotten as low as 159.5 pounds, but at the other extreme we weighed so much that our old mechanical scale spun past the highest mark of 280 pounds and wrapped around to go past zero again!

Over the last 20 years or so we have been testing various methods to scientifically master our fat allocation and burning system. We have attached a chart that shows our successes and failures over the last few years.

What we do know is:

Our eating patterns are closely related to how we feel psychologically.
Our feelings of hunger are exacerbated by holidays and close proximity to snacks.
Our body processes sugar as if it is crack cocaine, and if we eat sugar we experience "highs" and (unfortunately) "lows".
The medications we take have a great affect on how much we eat and how hungry we are.
Whatever mechanism in our brain that signals that we are full is either absent or malfunctioning.

About 10 years ago we discovered this excellent free book: [URL]https://www.fourmilab.ch/hackdiet/[/URL]

It is not only a book. There is a web interface and apps to track weight using sophisticated "averaging" methods. We have been logging our weight for that entire time but we lost 8 years of data and had to start over again in 2012.

Being obese, or even morbidly obese, is a very depressing situation to end up in. Our old plan from 2004 or so involved hours of exercise a day. It worked for a year or two until we tore the patellar tendon in our left knee. Up until that point we had ridden 95 centuries in less than a year. (A century ride is 100 miles on a bicycle.) We rode them very fast, averaging 16-18MPH. That plan allowed us to eat anything we wanted but when the exercise ended with injury we didn't stop eating.

Our new plan is stationary rowing (rowing ergometer) for 2,000 meters a day and a sugar restricted diet. The diet has a lot of meat (and fat) which signals the brain that we have eaten a lot even though it is not much. Our cholesterol count has doubled since we started the diet but we think it is better the be the proper weight with bad cholesterol numbers than to be morbidly obese with low cholesterol numbers. We could be wrong but there are other reasons that bear into this decision, like quality of life. Being "normal weight" is infinitely more comfortable and socially acceptable. Our previous injuries still hurt a lot but not nearly as much as when we are carting around a tub of lard.

Anyways, we could talk about this for hours and get even more boring. We'll leave it at this for now.

Chart:

The red line is the "smoothed average".
The gray line is actual weight that day.
Days above our "smoothed average" are like bobbers on a fishing line.
Days below our "smoothed average" are like lead sinkers on a fishing line.
The red line could be thought of as a fishing line.
There are days that we cheat on our diet. We try to do so scientifically. You may notice that we have recently found a way to cheat that affects the fishing line less than previous attempts. We think occasional days of sugar "shock" our metabolism and reignite our weight loss. Plus, we like sugary snacks!
We know when we are losing weight when we are freezing all of the time, even in 100 degree weather.
Our newest approach could be summed up as trying to be less extreme. (?)

[QUOTE=Nick;389112]Looking at the graph, I would say you are doing very well![/QUOTE]It would be easy to say that weight loss means that we are doing well, but we think that repeated losses and gains are hard on the body, so our (newer?) metric for success is a stable long-term weight loss.

Currently we are just exploring how our body reacts to different inputs. Ideally we would keep the weight at or around 170 pounds indefinitely. Using [URL="http://www.halls.md/body-mass-index/av.htm"]BMI[/URL] isn't a fool-proof method of determining ideal weight but it is better than just guessing.

agreed, have you considered joining or looking at the [URL]http://nwcr.ws/default.htm[/URL] which is a collection of data from people who have lost 30 or more pounds and kept it off for more than a year. Lots of good data on various paths to success. (some interesting to me are that merely by limiting the number of hours of TV a person watches per week can have a dramatic impact on long-term weight loss and walking every day is just as good a predictor of successful weight loss as running.)

I also recommend the book Diet Cults by Matt Fitzgerald (right up until the last chapter where he ignores his own science of diets advice and recommends his own special diet).

The TL;DR version of the book is that all diets are BS. And they all work to one extent or another. Find a system of eating that works for you without all the cultish trappings that go with popular diets. For example, the Paleo diet has some good things to say about the kinds of foods we overeat, but the historical narrative that Paleo dieters espouse is utter nonsense.

Did you create the smoothed red line, or was this a package from someplace? I notice that in the long trending sections the smoothed red line is always to the right of the detailed gray line. This is a problem with many smoothing methods. There are techniques to fix that. One of the simple techniques is called "twicing." This forms the "rough", so that

actual data = smooth data + rough data

Then apply the original smoothing process to the rough, and plot

smooth data + smoothed(rough data)

It sounds like this next storm is going to be very strong and possibly more coming.

Here's some back of the envelope numbers so far:
[URL="http://m.kcra.com/news/are-we-there-yet-how-much-more-rain-will-end-the-drought/30086452"]'Are we there yet?': How much more rain will end drought?[/URL][QUOTE]The California Department of Water Resources said it relies mainly on eight precipitation gauges in the northern Sierra Nevada Mountains to determine how far the state has to go to end the drought.

Stretching in a line from Mount Shasta to Highway 50 in El Dorado County, the gauges are located upstream from the state's major reservoirs.

"Right now we're at, I think, 107 percent, of average," said Jay Lund, director of the UC Davis Center for Watershed Sciences.

However, state water managers said precipitation will have to reach at least 150 percent of average between now and next fall to end the drought.

"We're still very, very early in the wet season. And the rest of the wet season could just as easily be dry as wet," said Lund.

In an average year, the eight gauges record about 50 inches of precipitation.

In order to reach the state's goal of 150 percent of average, at least 75 inches will have to fall.

As of Friday, the gauges had recorded 11.5 inches, or about 15 percent of the state's goal.

In other words, if California's journey out of drought were a trip from Sacramento to Disneyland, we would have traveled 61 miles of the 410-mile distance and be on Interstate 5 just past Lathrop.[/QUOTE]

The trouble that often happens is people (reporters) quoting the wrong figures. Saying "we are at 107% of normal" often leaves out the implied (or explicitly stated by the person-in-the-know) "for this point in the season" or maybe "for the calendar year". Saying that the rainfall is at 107% of normal at the end of October is different than saying that at the end of April. For my job I used to have to keep a close eye on the weather, the rainfall in specific.

I could go all Rainman on the subject, but I won't. Suffice it to say that I don't trust any short reports from TV news. Print and NPR are much better at getting the complete picture.

W.r.to the various touted statistics, all I know is here in Silicon Valley we've already gotten more rain in December than we did all last winter. Let's hope the trend continues, because the only way to make up a huge multiyear deficit is to run a similar multiyear surplus. (And the timescale for replenishing central valley aquifers is likely much longer, due to "deficit spending" on top of "collapsed revenues". I'm afraid Keynesian economics fails epically in the field of hydrology.)

"Without resistance" is overblown - compare to what the discoverers actually say:
[quote] co-researcher, Bonn's Tanya Schneider, explained in a teleconference that teixobactin belongs to a new class of compounds and kills bacteria by causing their cell walls to break down. [b]It seems to work by binding to multiple targets, she said, which may slow down the development of resistance[/b].[/quote]
Prediction: If the new compound ever does pass human trials, it will quickly become so over- and mis-used that resistance will develop nonetheless. The only long-term solution here is to drastically cut our overuse of antibiotics, in both human medicine and animal husbandry.

Edit: Okay, even though it doesn't say in the article that the data is random, I'm assuming it is. But if we(the human race) learns to do this stuff with non-random data, holy crap. The following is the rant I posted before I had the random data thought, please be merciful. :)

Can scifi novels count as prior art, because if this weren't a science article, the author of the Ell Donsaii scifi series would probably be calling his lawyers right now about plagiarism. This is spot on to what Ell Donsaii made, except that stuff is supposedly happening 20-30 years from now if you think of the book as actual history. And, yes, I know it's just a story.

If this concept makes it to production, I'm going to write to Mr. Dahners and ask him for investment advice.

I mean, think of the potential for Chinese dissidents. You could hook up one of these things to a high throughput internet connection in the US and the only way to trace it would be to use normal detective work on the data. And even then the Chinese government wouldn't be able to do much about it. You could transmit data from anywhere in the world to anywhere in the world.

The million dollar question, though, is whether this is limited by the speed of light. Even if it's exactly as fast as light, think of the potential for things like exploration of the Titan moon, you wouldn't even need to worry about intervening material like with regular radio waves. I could hook my tablet up directly to my home network, go anywhere in the country and have the equivalent of a direct connection with no NSA spying unless I was already compromised. The Netflix security measures they implemented recently wouldn't work anymore because people would simply need a willing American to plug them into their network. An extra step that's a bit difficult, but definitely not impossible.

Not only what I said before, but think of the potential when it comes to internet lag. COD fans would no longer be able to blame lag on their hit to death ratio because they'd be able to pay for a direct connection to a server. You could have your local cable provider deal with the hassle of handshaking with a server, then you'd simply use a special dongle to connect to said server; 2 hops there, 2 hops back and way less lag. Hell, while we're talking about servers, let's all get Google Fiber without any actual fiber in the ground. How good is cell phone service going to be if we don't need towers? The only difference between a cell phone and a land line would be that the cell phone needs a battery.

You could forget about laptop hard drives, you'd just need a monitor, a keyboard and a computer SOMEWHERE. Off-site backups at the speed of your USB port.

I could go on forever.

Naa, naa, rubber and glue and all that.

If you have two quantumly entangled particles and the ability to transmit their states in a non-random fashion you, at the very least, have a transmitter and receiver combination. Add some research assistants and lots of money, let sit for a time, and you have a ground-breaking communication technology. Obviously, there's a lot of middle ground to cover, but anyone can see the possible potential in this sort of thing.

I seem to remember someone saying you had a college degree, not sure how you can get one without the ability to think. Did it have particles of sugary candy sticking to the plastic it came in?

Quantum entanglement means 2 particles share similar states, true or not?

Quantum entanglement isn't impaired by intervening material, true or not?

You can't spy on what the 2 particles are saying to each other without revealing your eavesdropping, true or not?

If you add to that the assumption that you can control the state on one particle and have that transferred automatically to the other, that could be used as a form of communication, true or not?

No shit, dude, we barely understand it at all. I was talking about possibilities, not confirmed facts.

It's like Edison and the telephone, he could only guess at the potential of his device.

You're kind of a glass half empty kind of guy, huh? You ever fantasize about the possibilities of certain scientific discoveries? Like, I don't know, the possibility the speed of light limit can be worked around, or that maybe someday the cost of space travel will be pennies on the pound, like with aircraft?

I wasn't living in a fantasy-land, if we discover the ability to transfer non-random information using quantum entanglement, that opens a whole new world for us. Changing exactly one variable is science fiction, not fantasy. And since it was only the one variable, I considered it okay to post. If you re-read what I post, everything is totally possible with the new assumption of non-random information.

ce Setting The Record Straight For Alan Turing
 
[url]http://www.npr.org/blogs/13.7/2015/01/06/375356142/setting-the-record-straight-for-alan-turing[/url]

[QUOTE]Imagine, for a moment, that Albert Einstein's greatest contributions were kept secret at the highest levels of government. Imagine, for a moment, that while still relatively young, Einstein was prosecuted, shamed and driven to suicide for the inclinations of his affections. Imagine, for a moment, that in the wake of the secrecy, the shame and the suicide, you never knew Albert Einstein's name.
Seems crazy, doesn't it? In many ways, however, that narrative is the story of Alan Turing. Thankfully, it's a story that is finally getting aired in popular culture through the new film [I][URL="http://www.imdb.com/title/tt2084970/"]The Imitation Game[/URL][/I].
Until relatively recently, most folks wouldn't come across Turing's name unless they had a certain kind of computational orientation. "Turing" doesn't ring the same bells as Einstein, Newton, Darwin or even Heisenberg, Watson and Crick. But, without doubt, Alan Turing should be on their list of science giants.
It's not just that Turing's work was worthy of a Nobel Prize. He went far beyond that. Turing possessed an epoch-making genius of the highest order — and his impact on human civilization is in line with the heights that kind of genius yields. That's why Turing's omission from everyone's list of super-scientists is so galling. But worse, still, are the circumstances of that omission's occurrence, driven by a confluence of two remarkable factors — an accident of history and pure narrow-minded fear.

If you want to know about Alan Turing's life and his achievements, read his biography "Alan Turing: The Enigma" (ISBN 9781784700089) by Andrew Hodges, a fellow at Oxford who developed twistor diagrams with Roger Penrose. It is a highly scholarly account, and a captivating read.

For just a taste of it, watch the play "Breaking the Code". This ran in London's West End and then on Broadway in New York in the 1980's before being made into a short film (with the same name) starring Derek Jacobi. The film was also broadcast in the US. And if you are in England, a visit to the museum at Bletchley Park and the National Museum of Computing next door is definitely worthwhile.

But, apparently, the makers of the new film "The Imitation Game" missed all this and are convinced that they are bringing his story to the world for the first time. They also gave themselves the right to change important facts about what happened.

kladner 2015-01-11 17:01

Yes. I am aware that the are considerable faults in the current offering. It is something for Turing to get any attention at all in the wider world.

This is the part where you are utterly, totally, "I've never read the science" mistaken. Your speculation of a future "figure out" is on the level of warp drives and antigravity fields. If such communication exists in the future such as you dream, it won't be because of quantum entanglement.

This is not a matter of a lack of imagination, and you should read even a basic wiki explanation of entanglement to get an idea why we're replying the way we are.
