Art (a.k.a."Skip" -- but I'll artfully skip that):

First, I am impressed by your question, "Is learning the same thing as being taught?"  It seems an almost obvious question, and yet it obviously isn't.  Having taught at one learning level or another and in one educational venue or another for almost forty years, the question gave me pause.  I'll skip my thirty years teaching graduate school (you never really know what those damned fools have learned  -- by the time they've gotten to you, they've learned to "game" the system so well that they can put on a good show, whether they really know anything or not) and go striaght on to my days of teaching Middle School -- now there's a lot who, despite their best efforts, will end up being pretty straightforward about what they think and what they've learned (or not learned).  You can teach and teach them -- but that doesn't mean that they've learned diddlysquat.  On the other hand, they may have learned any number of things that you didn't teach them, or didn't intend to teach them.  I feel pretty certain that my Middle School students (most of whom I had great respect for) learned a lot from me that wasn't in the school curriculum (but don't tell their parents!).

Second, I am impressed by your comment, "At the heart of learning is observation and organization."  Nearly every school I currently know -- Middle School, High School, College -- states that it teaches "critical thinking" (having tried to apply my own critical thinking to this term, I would really like to see what this means in action).  What I think might be meant, or should be meant, is this matter of observation and organization.  This is actually at the heart of what we should be teaching:  that one should learn to observe and to organize, and how one should observe and organize, and why one should observe and organize.  The follow-up, as you note, is assembling and assimilating enough relevant data on a given subject to be able to make some sense of the bigger picture (and perhaps connect it with other "bigger pictures").

I'm intrigued by the information you offer on Camp Evans, in Wall, New Jersey.  Because my minor subject in graduate school at the University of Delaware (through the Eleutherian Mills- Hagley Foundation, mentioned just above) was "The History of Technology," and because I was the first president of the Washington, D. C. chapter of the national Society for Industrial Archeology, I remain interested in many things technological, though I'm a historian, not a scientist.  Two years ago, while on vacation, I read A. T. Story's book, The Story of Wireless Telegraphy (1909), happily included in Kessinger Publishing's Legacy Reprint Series, and which I had found in a used book store.  Certainly part of the story (though not all!) belongs to Marconi, and, yes, as I am "into these things" (and museum sites as well), I would love to visit you there.  (I cannot find Wall, New Jersey, in my atlas, but it seems to be south of Asbury Park and not too far from Allaire, with which I'm very familiar, and perhaps close to Spring Lake, where my wife and I spent a lovely overnight a number of years ago as we were touring the complete New Jersey coast.)  I have no present plans to be in that area anytime soon, but I'll keep your offer of a visit in mind.

[N.B.:  Part of the Camp Evans site looks like the Green Bank Observatory in West Virginia, which we visited several years ago.]

If anyone is wondering where I might have been during Woodstock in '69, here it is.  That's me, front and center, as usual, having just returned to base after about the 10th of my 32 recon patrols that year.

Skip and Phil - r.e. "Observation and Organization"

Most people, if you walk briskly through a 14x14 room with them and ask what they saw, will tell you they saw the exit door (and not much else). While observation CAN be taught, it is usually a skill that is learned out of some necessity.  In my case, playing baseball as a kid, running cross country in crowds of other runners, and all sorts of activities in military exercises and missions were my "necessities".  Once learned, the skill becomes habit and even today I can just about see the whole room when I walk through with no concerted effort. Organization is similar in its learning habit, but can be more readily taught by rote. I would include a third discipline in this group - anticipation.  This was particularly critical in the military, and like observation, once learned becomes almost habit.  My main activities these days are bridge and golf, and these disciplines are most evident in the more successful players of both.

In my everyday life these days, however, I find that a fourth discipline - laziness - has permeated my existence.  So much so that I had to hire a housekeeper so as not to be "left in the dust", so to speak.  I do still try to anticipate, observe, and organize those nasty maintenance chores that pop up from time to time.

Larry, I aspire to that lifestyle, but cannot hit a golf ball. Fifty years ago, I was somewhere in the Pocanos during Woodstock, safe, despite diving tanks whose regulators failed, followed by 45 years of marriage to Gwynne.

Hi Phil,

Wall is in the middle of the places you described, on the edge of Shark River. Allaire is a bit west of
Camp Evans. The cross route is 138, one exit past the Route 18 (N-S) exit. Camp Evans is off of Marconi Road of course.

If you would like to see the Museum, and would want to make a trip here, you could fly into
Newark Airport and then stay with us. We live in the north part of Toms River, about 12 miles from
Camp Evans. We have an extra bedroom for just such opportunities, and it makes the trip a bit
less expensive when you have friends to stay with.

While you are here, you should also visit Grounds for Sculpture. It is over 40 acres of sculpture that
was developed by one of the J&J boys, who didn't fit into the business. It's a really interesting place
and will take 3-5 hours to go through. There is a restaurant there, but you need to make reservations
a week or so in advance to be assured of an inside seat. Many weddings are done at various places
around the Grounds. It is located near Trenton, NJ, about 35-40 minutes from our home.

Weekends are a good time for both places. A trip where you arrive on Friday, do both attractions
and then return on Monday or Tuesday would make a nice extended holiday. Once the kids go back
to school, the pace slows a bit.

Of course you can also take in a play in NYC. There is a train to goes to Penn Station about 5 miles from here, right along the Shore. A bit farther north, you can get the Sea Streak Ferry, which is a passenger only, thin hull catamaran that makes the trip into NYC (34th street) in about 45 minutes, less than half the time
the train takes. The trouble is, once you get into NYC, there is so much to day that you can get lost
for 2-3 more days at shows and museums. Of course, lodging in the city makes the trip much more expensive so that may not be that appealing. You can get matinee tickets in advance for a substantial discount, and if you are willing to take a chance, you can get tickets the day of the performance for almost nothing. We caught the Carol King (Beautiful) musical about 5 weeks ago and it was great. Reminded me of my old stage crew days at Walnut Hills.

In fact, if you wanted to spend a week in the Garden State area, you could spend 2-3 days here in NJ and
then get a hotel in NYC and spend another 3-4 days there, and fly into and out of Newark, or into
Newark and out of LaGuardia. Let us know so we aren't off doing something ourselves. If you want to drive up 95 from Virginia, its about 5 hours depending on how you hit the beltway around DC and Baltimore. That would give you a car here, and a bit more flexibility.

In any case, this area is a nice place to visit. If you come soon, the pool may be open still. It closes in September. Have family arriving on the 23rd and leaving on the 27th, but before or after works. If your journeys bring you north, let us know and we'll keep the lights on for you.

Blessing on your family,

Although we have no present plans to visit the area, we will definitely keep your information in mind (possibly a mid-Fall weekend trip?).  Because my sister and brother-in-law were living in Barnegat, New Jersey (circa 1968-1970) when I was a student at the University of Delaware (my brother-in-law was the Presbyterian minister in Barnegat at the time), I visited there often, and my elder niece was born in Toms River in 1969.

We go in and out of New York City periodically, though less so since my wife's aunt, who lived in Queens and with whom we used to stay, died.  We have recently had pleasant stays at the Edison Hotel, just off of Times Square and very convenient to the theaters (I stayed there in 1959 with my grandparents, when we saw the inaugural production of The Sound of Music with Mary Martin and celebrated New Year's on Times Square -- woo-hoo!), but since we learned that it is owned by Donald Trump, we are looking elsewhere to stay.

At any rate, we welcome your information and invitation, and we will keep in touch.

Larry:  Wow!  I'm impressed by your analysis.

For over thirty years I have tried to teach Observation to my graduate students in Museum Studies.  (This is essential to analyzing any object in a museum collection.)  Every semester I read to them the opening excerpt from Conan Doyle's "The Adventure of the Blue Carbuncle," wherein Sherlock Holmes explains to Watson how to examine an object for clues.  Holmes says to Watson:  "Here is my lens.  You know my methods.  What can you gather yourself as to the individuality of the man who has worn this article?"  And Watson's response is:  "I can see nothing." . . . "On the contrary, Watson [says Holmes], you can see everything.  You fail, however, to reason from what you see.  You are too timid in drawing your inferences."  (In other words, he "sees," but he does not "observe.")

You speak of "necessities."  You are quite right; I told my students that they had to look at a given object and to "keep looking."  What are the oddities, the discrepencies from other objects?  What stands out?  What distinguishes this object from other similar objects?  And the end question is "Why?"  Again, as you suggest (though we are talking about completely dfferent fields), if one consistently steels oneself to focus on observing and examining the object closely and carefuly, it should become, of necessity, habit, and therefore become one's professional practice.

Anticipation:  I suppose in museum work this amounts to "what to look for."  If you have read the above paragraph carefully, you will see that, as one develops the "eye" of observation and analysis (which is why I told my students to look and look again -- in other words, don't "assume," but see if your thought is confirmed by your observation), one learns to anticipate what one might expect to find as visible evidence of a cultural reality.

Finally. Larry, no, it is not laziness  -- it is relaxation.  There is a difference.  I spend my time in retirement doing what I call "semi-gourmet" cooking, and in napping, and in writing these presumed amusing and/or interesting feuilletons (you can look it up in the dictionary), hoping that someone -- anyone -- gets something of the same enjoyment out of reading them that I get out of writing them.

Arthur (Skip) Gasch

Larry, Phil,

Regarding learning to organization information and anticipation, here's a point. If you walk briskly through a room, what you notice is what is moving, because that's how the eye organizes stuff. What's just hanging out the eye/brain dismisses. A guy in neutral clothing hang out by the wall and not moving (except glacially) is missed. Benevolent penetration of highly secure facilities by such people succeed.

Yet, if properly organized by a technology that builds a model based upon anomalies, causes such a person to stand out immediately. Humans haven't learned to do that well. Anticipation causes one to scan for what they expect, and minimizes their quality at discerning actual content. What do you expect to see in the picture below.

 

Did you see in it? If nothing, you're dead.

I won't answer, because I'm dead (even after referencing Richard Connell's "The Most Dangerous Game") -- but then, my eyesight isn't what it used to be (oh, wait! it never was! -- though never quite at the James Joyce level).

Wow Jeff that was quick! And I'm heartened by your willingness to say that someone - anyone - with a different point of view, if supported by evidence, might be right. That's a welcome attribute in a post-truth, non-evidence-based milieu, which is I believe a French word and thus suspect in some quarters.

Philip Spiess

But Jerry, where is the umbrella (or scissors)?  There is always an umbrella (either rolled up or open) in those pictures!

And Paul, you are correct!:  milieu is a French word; it means (in Middle English) "the toilet in the old mill" (cf.,  the phrase "Gardez l'eau!" interpolated into English as "loo").  The French couldn't understand why the English would put a toilet in an old mill, being used to using chamber pots and fireplaces (well, in the summertime -- don't ask) themselves, which is why they translate milieu as "environment" (probably with a question mark at the end).  The French themselves prefer, in such circumstances as, say, a toilet in an old mill, to use the phrase mise en scene, which means "a miserable scene" (vide a toilet in an old mill) or, sometimes, "surroundings of an event," which is a very polite and delicate -- and very French -- way of saying "going to the toilet in a mill."  [The English novelist George Eliot, who much preferred reading German to French, turned the whole thing on its head, putting a dent -- or  "dental" -- locus on the mill suroundings -- or "event" -- by focusing on one's mouth, rather than at the other end, when she wrote a book entitled The Mill on the Floss.  You might think that in this case it should read The Floss on the Mill, but she was doubtlessly translating from the German, in which everything is always backward, starting with the verb at the end of the sentence.  So geht es alles in eine fremde Stadt.]

Phil, Jeff, Jerry, and Paul,

A hint on the jungle trail pic. There are 3 threats, although if there had been others, they too would have been detected. Which side of the trail are they on? There is camouflage involved here.

I will ultimately show them, but have a question, "What AI algorithm could be used to detect threats, given that in one setting the "threat" may be very different than in another?" What if the setting was desert or arctic? What if the threat were different? In th pic I sent the threat is snippers.

Could one algorithm work for all threats in all settings? If so, what "attributes" would it have to have. It certainly could not be "rule-based." Does the content of the picture itself show us "where the needles in the haystack" are hidden? If so, how? If not "ruled-based" could it be a neural network? But if it was, would it have to be
"retrained" for each different "setting," it would have to work in? What would happen to the node-values of all the previous learning if something "new" was discovered?

The solution doesn't depend on increasing computational speed, or is information organization more important to intelligence. After all, CPU clock speed beats brain processing time, by a lot, but, the brain usually "sees" things that self-driving cars miss. What is that?

Could it be that no "algorithm" at all is required to see the "threat?"

It's an interesting discussion so far.

Are we quite sure Skip Gasch's photograph wasn't taken in Krohn Conservatory?  (Just askin' -- in which case the threat would be the hazard of water on the slippery steps just after it opened in the morning.)

Paul - boy, were YOU off-base. Those were Hong Kong hookers.  I never made it to Saigon during my tour over there.  Took my two R&Rs in Hong Kong and Sydney.

Skip - as to the pic, my eyes are failing me these days with retinal spots and cataracts, so the only threat I see is the likelihood that I'll trip on the rock in the path. 50 years ago would have been a whole different picture (to me, anyway). btw - I drove up old Paxton Ave last week, Not much is changed from our days there.


08/12/19 11:04 PM #4240    

 

Arthur (Skip) Gasch

Let's take this back to the AI universe. How do you find a needle in a haystack, or in our case a snipper along the trail? By the differences of the properties. You need a method of storing data that catalogs differences. It is inherently "intelligent" and useful for all sorts of things.

Imagine a second picture of some white blood cells on a slide smear. If the information system has seen some cancerous ones, and has catalogued their property differences from non-cancerous ones, you can simply build a catalog of cancerous cell properties, and run the hundred thousand or so cells in a slide sample and instantly find the location of all the cancerous ones -- Making pathology tests a bit faster to perform

Does that make the approach AI or deep learning? It's analytics by example at least, and the
analytics queries are near real time.

Hey Paul,

about the length of rope, I didn't think it was Rudy, I was thinking more along the lines of Bill Clinton.
I think it will come to light whomever it was, seem to be something DOJ will pursue.

Philip Spiess

Art:  Your most recent example has also brought the discussion back to my area of expertise -- deciphering/analyzing museum objects.  I constantly would tell my students "Look for the differences!  What distinguishes these two objects, which look basically the same, one from the other?"  (An exercise I gave them was this:  I took a large selection of screws, nails, bolts, nuts, wing-nuts, eye-screws, etc., of various sizes and kinds, into class and told the students to separate them into distinctive categories, as they saw fit; having been divided into a number of small groups to carry this out, the different groups often divided them in different ways -- which was perfectly harmonious with the activity.)

Having decided what makes them different, the next, and central, question was "why?"  Why did the maker (or the culture) decide to change something? did it make it work better? (practical change); did it make it look better? (aesthetic change); did it make it stronger, lighter, faster? (technological change); was it made out of cheaper or more available materials? (economic change) -- and so on.  Examining the differences (minute as they might be), and the likely reasons for them (not always knowable or deductible), was key to unlocking information about objects and their cultural relevance.

By the way, that picture on the left looks like a late 1950s map of the areas of semi-submerged land in south Florida that folks were trying to sell as subdivisions off ads on buses and early TV when we were in school.  (If you look closely, possibly under ultra-violet light, you will see the alligators -- or the umbrellas.)


08/14/19 12:31 PM #4243    

 

Arthur (Skip) Gasch

Hey Phil,

Interesting.

Here's another wrinkle. Which items you find (in a dig for example) should be grouped with the other items, to form a 'set' of similar items.

That same issue arises in IT land, where a group of responses is plotted in any number of dimensions. The concept of "distance" is really about that, and gets very interesting as the number of dimensions increases. In two dimensions, it's as simple as getting a 'measuring' stick and using it.

In three dimensions, well that geometry or perhaps calculus, although the taught us calculus wrong at Walnut Hills, oh well.

What about in 7 dimensions or 100 dimensions? Every independent property of a thing is in fact a dimension. In the case of your nuts and bolts example, what the bolt was made of is a dimension. Was it wood, brass, iron, steel, lead... and what were the trace elements? If one digs through two archaeological layers, or if they intersect, and you have 12 bolts, that in one dimensional plain are some "distance" from each other, how do you group them into sets? What if they aren't at the same depth?

As TV reminds us, "Now we can drain the {ocean, land, whatever} and simply see them in 3-D (or in truth in N-D) so the issue of whether the lead bolt at depth 1, is part of the groups of 2 other lead bolts that are at depth 2 and 3, makes the exercise of grouping them.

Any thoughts about that? The notion of grouping items (in the museum) and how to detect the
forgeries from the real things? There is a simple way to do that.

Perhaps we should apply your technigues for identifying which of us humans could be differentiated into various property classes, based on subtle differences in how they present themselves. What do you think? Is there a sacred group and a secular group, and if so, what properties differentiate them? Are there degrees of secularness, and if so, does it matter?

Art:

This is getting interesting.  The whole question of grouping objects is a complex one -- and one that one needs to be cautious about in museum work.  Early archaeologists in particular (such as Schliemann at Troy or Sir Arthur Evans at Knossos) were eager to group objects they found according to the preconceived notions they had of the sites they were investigating.  One hundred fifty or even one hundred years later, more recent scholarship and re-investigation of the sites often suggest that things were (or could have been) entirely "grouped" differently.  As museum professionals, we always spouted (and often adhered to) the concept of placing the object "in its context" -- but who decided what context or which context often determined how the object in question was interpreted to the public -- a remnant of Greek sculpture, for example, could be interpreted one way in an art museum (as an "artwork") and another way in a history museum (as a "signifier" of a period in an historical culture, such as ancient Greece, or as a token of an archaeological find).  A longtime director of the Corpus Christi Museum in Texas, Albert Heine, often gave his well-known speech on "Founding a Museum Based on a Nail," in which he would interpret a whole world of history, art, technology, science, and economics based, in turn, on the different contexts into which he could place the nail.

Now, although I am no "underground" archaeologist (though I was the founding president of the Washington, D. C., chapter of the national Society for Industrial Archeology, a largely "above-ground" archeological group), I have been associated with enough "real" archaeologists to know their professional methods.  When excavating an archaeological "dig" underground, they plot "distances" in three dimensions by establishing a horizontal grid of smallish squares on the surface, which they then extend downward through the soil in pre-determined measured levels.  It is of prime importance to them to note the "grouping" of objects within the squares, to determine the relevance of relationships between and among the objects ("artifacts") found.  Likewise, in most cases, each level further down in an archaeological dig is assumed to be a previous ("earlier") level of cultural activity, and thus the objects found there are likely to be dated to an earlier time, unless other evidences indicate otherwise.  (Heinrich Schliemann is supposed to have "discovered" -- or uncovered -- no less than seven layers of previous Troys.)  Needless to say, all of this rarely accounts for movements within the earth, including significant upheavals.  [I used to think that a useful exercise for training beginning archaeologists would be to have them sift through a cat's toilet box, eventually emptying it, but I never put the experiment into execution.]

And this is in some ways no different from the ways in which archivists operate.  Much of the time, when professional archivists are given or locate a significant cache of important papers, documents, stacks of bills, laundry lists, loose letters, interspersed journals, schedules of meetings, etc. -- i.e., totally unorganized, filed, or categorized documents -- they carefully move them in situ to where they will inventory them, leaving them in the stacked order in which they found them, because the "unorganized" order is a natural order of the way in which the papers' owner left them, and so there is often a connection among the papers located together.  Only after looking through those connections, and ascertaining them if possible, do archivists organize those documents by subject, date, or persons, or whatever system of organization they may be using.

Now, as to forgeries, that is a whole different subject!  (I'll try to be brief here.)  Forgeries of objects have existed since time immemorial, largely based on the presumed possible economic worth of said forgery.  (The Victoria & Albert Museum in London, a teaching museum of the decorative arts, purposely set up an exhibited collection of established forgeries in the 1850s, so that students could study them -- it's still there and is still used for those purposes.)  Of course, nowadays we have many scientific ways of testing objects thought to be forgeries, rather than just by sight -- but see some of the articles on the (New York) Metropolitan Museum of Art's famous "Etruscan Horse" sculpture -- after almost seventy years they're still debating:  Is it or isn't it a forgery, or at least not what it seems?  My own actual "real life" example was simply proved:  I had catalogued (first) the complete dental collections (going back to the 1830s) of what afterwards became the National Museum of Dentistry in Baltimore, and then catalogued (second) the complete dental collections of the National Museum of American History at the Smithsonian Institution.  (Cataloging museum objects is a complex process which I won't go into here, but computerization has eased much of the task.)  There was a reason I was contracted to catalog both collections:  the Baltimore museum's objects had been loaned for thirty years to the exhibits at the Smithsonian, and there was a serious dispute over whether all of Baltimore's objects had been returned by the Smithsonian.  All of the personnel involved in the initial loan agreement had died; I was hired to sort it out -- which objects belonged to which museum (all that I know about dentistry itself -- except that it hurts -- could fill a tooth).  The particular objects in contention were, historically, the earliest in the collection, and therefore (presumably) the most valuable:  they were two or three dental instruments of the 15th century, rare in any collection; Baltimore claimed them as theirs; the Smithsonian said they were theirs.  I studied them by sight at length for two or three days (see my several posts above about "Look and look again!" at the objects) -- they appeared way too new to me, but even antique objects can be "gussied up" to look fairly new.  Then it finally hit me:  the screws in the objects were an anachronism -- such screws did not exist in the 15th century!  These screws were too perfect; 15th-century screws were exceedingly clumsy and coarse by comparison.  So where did these instruments come from?  I had an inkling of a clue:  Baltimore (which at the time of its loan had no museum -- all its objects were in storage, hence its loan to the Smithsonian) had loaned its objects when the Smithsonian first set up its Dental Exhibit in the Old U. S. National Museum (now the Arts & Industries Building) before it was moved to the new (1964) National Museum of American History's "Hall of Medicine."  There had been an exhibits laboratory at the Smithsonian which produced replicas of objects which the Smithsonian needed to tell its historical story, but which it did not have in its collections.  Unfortunately, I found that the records of this lab no longer existed -- but the evidence was pretty clear to me:  these replicas (not forgeries, per se) had been manufactured by the Smithsonian to fill out its interpretive story.

As to differentiating human beings into distinctive or various classes, I am opposed to that:  despite the 39 "Ethnic Heads" that are sculpted on the outside of the original Library of Congress building (now called the Jefferson Building), chosen by the chief of the Smithsonian's Department of Anthropology (Otis Tufton Mason) in the late 1880s (and very interesting they are, too), I learned in my doctoral work on evolution, studying under one of the editors of the Darwin papers (located at Cambridge University), that the idea of "Human Race" does not exist in real science, but is merely a cultural construct -- and one that has not served humanity well.

Hi Phil,

Above are various instances of thee types of things, one red, one yellow, one blue.
The data has been fully normalized and is devoid of metric system scaling and affine distortions.
Now, how many "clusters" are there of each of the three colors? What "rule" determines how
to answer that question?

In some ways it isn't a fair question, because these things are higher dimensional, and have been
collapsed mapped onto a 2-D surface, but imagine they are locations in a 3-D space. Then again,
how many clusters or groups of yellow objects are there? and how many reds and how many blues.
Are there some singularities of yellow and red or blue ponts plus some clusters? If so, how many?

What is the frame of reference that caused the collapse mapping? Does that affect your answer?
Suppose the bottom right corner of the picture is the 'nearest' to you and the upper left corner is the farthest point away in this hypothetical 3-D space.

What if this is a 4 or n-dimensional space. How does the notion of nearest neighbor come into play? A cluster might be all objects of one color that have a distance to each other of less than K, a specific
distance. Would that make clustering easier and reduce it to a mathematical exercise?

Are the three yellow blocks singularities, or do they form their own cluster?
Red, blue and yellow here are multiple instances of only 3 properties. What if there were 1,000 colors because there were 1,000 parameters, or say 6 million colors in a genome (such as in the lifetime medical record the government is calling for)? It gets really interesting then?

Do you suppose people would be interested in investing in an AI solution for such problems, that could also expose relationships between the three colors and other outcome variables, such as the illness or wellness of the patient, or their survival at 2 years from a treatment, or their likelihood of readmission to a hospital ER within the next 30 days?

We have an information organizational structure that makes answering such questions simple algebra. We could be more specific under an NDA. Anyone interested in pursuing such matters.

Art:  Well, you've hit on the same set of inquiries, it seems to me, that I posed to my beginning museum students with my exercise of sorting out the bags of screws, nuts, bolts, nails, etc.  (To my knowledge, no one else in the entire set of professors of Museum Studies, past or present, in the whole United States -- including those in my own department at The George Washington University here in Washington, D. C. -- ever conceived of such an exercise, or thought that these were questions that even needed to be addressed.  Yet they open up a vast range of variable analysis and recognize that there are many things to be considered under the sun.)

You talk about "draining the ocean" to see certain things.  It was not until humans took to the air (and some time after that!) that archaeologists discovered that centuries-old underground remains of former civilizations (say, the Romans in Britain) could be easily seen or identified by the way in which grasses or other agricultural crops grew over them, even after millenia had passed, making them distinctly outlined areas when viewed from the air (no, I'm not talking about "crop circles").  Thus archaeologists knew where to dig.

On another note (we won't talk about "draining the Swamp" here in Washington, which is exposing all sorts of things), for centuries there had been stories and rumors about two large Roman ships, built by the Emperor Caligula (one absolutely palatial), that were sunk at the bottom of Lake Nemi, south of Rome.  Occasionally, over the many years in question, fishermen had brought up, say, a golden goblet or a portion of a statuette that suggested that something was indeed down there.  So finally, Il Duce, Benito Mussolini, in 1927 ordered Italian engineers to drain the entire lake in order to see what was down there.  And, lo and behold! there were, in fact, the two ships of Caligula that history had said were at the bottom of the lake!  The larger one included marble fixtures and mosaic floors, a heating mechanism, plumbing, and baths, technology that was not believed to have been possible until much later.  Mussolini had the two ships removed to Rome by 1929, and in 1936 the museum that was built to house them opened to the public.  However, World War II then broke forth, partly due to the machinations of Mussolini, and in 1944 the entire museum, ships and all, was destroyed by fire from Allied bombing.  Moral:  They existed for almost two thousand years, were recovered for fifteen, and then pffft!  O tempora!  O mores!

AND -- back to Skip's question:  How do you find a needle in a haystack?  Applying Occam's Razor to the question, and referencing Larry Klein's picture at Post # 4227, I proffer that, nine times out of ten, you find the needle by just casually settling back into the haystack (well in, mind you) -- and . . . the needle will find you!
