invisibility

New Steps Towards A Real Invisibility Cloak
Invisibility technology: no longer just for rarefied parts of the spectrum

Ouch, Harry Potter. Your new movie doesn't premiere for two months, yet real scientists are already one-upping you

Researchers at Lawrence Berkeley National Laboratory and Cornell University both said last week they've designed invisibility cloaks that work in the visible-light spectrum. OK, so they're not big enough to cover a budding young wizard sneaking around at night, but hey, it's a step.

Two teams, led by Michal Lipson at Cornell University and Xiang Zhang at the University of California Berkeley, said their nano-scale invisibility cloaks allow light to flow around a hidden object as water flows around a rock. The cloaks contain a mirrored edge with a bulge that appears as though it's flat.

The feat solves an age-old problem faced by children huddling under blankets: You'd still see the cloak, but now you would have no idea what lies beneath.

Previous work on invisibility cloaks, including at Duke and UC Berkeley, only worked for light that human eyes can't see, like radio and microwaves. But new research shows silicon nanoparticles, as opposed to aluminum or other meta-materials, can work at shorter wavelengths -- even in visible light.

"Our optical cloak not only suggests that true invisibility materials are within reach, it also represents a major step toward transformation optics, opening the door to manipulating light at will," said Xiang Zhang, director of UC Berkeley's Nanoscale Science and Engineering Center.

Perhaps unsurprisingly, the U.S. Army provided some of the funding.

The cloaks reflect and bend light in a way that fools the observer into perceiving a flat surface. The cloaks' nanometer-size silicon materials are spaced apart at varying densities, so light flows around the bulge without distorting the view. A person looking head-on at the bulge would see only a flat plane mirror.

The main problem is scale -- both cloaks are wee things that might obscure little more than the eye of a needle. The Cornell cloak works for light that's just barely visible to humans; the Berkeley cloak only works for wavelengths barely outside what humans can see.

Zhang said it was easy to make and should be easy to scale up into visible light, however.

"Our next goal is to realize a cloak for all three dimensions, extending the transformation optics into potential applications," he said. Applications like sneaking around where one is not allowed, perhaps?

father-daughter problem

"one critical time a daughter needs her father --during adolescence, when she is changing physically and is beginning to question who she is as an adult--often is the time the father begins to show less affection. "Ironically, just as a teenaged girl is entering adolescence and going through the outward and often awkward change that goes along with puberty, her father pulls away from her because he isn't comfortable with his daughter's new sexuality. So just at the point when she needs approving hugs from her dad the most, he's less likely to give them to her, and she may not understand why he's pulling away; she may think he approves of her less."

facts on fathers and daughters

Fathers and Daughters: Eye Opening Facts


By Linda Nielsen, Ed.D.
Author of Embracing Your Father: Building the Relationship You Want with Your Dad


Healthy Lunchbox


As the parent of a daughter or as someone whose spouse has a daughter, we strengthen father-daughter relationships in our families by being able to separate “fact from fiction”. Despite what we see in many movies, TV shows, advertisements, and children’s books, recent national statistics and recent research from leading experts in psychology and sociology, show several facts to consider:

* Fathers generally have as much or more impact as mothers do in the following areas of their daughters’ lives: (1) achieving academic and career success—especially in math and science (2) creating a loving, trusting relationship with a man (3) dealing well with people in authority—especially men (4) Being self-confident and self-reliant (5) Being willing to try new things and to accept challenges (6) Maintaining good mental health (no clinical depression, eating disorders, or chronic anxiety) (7) Expressing anger comfortably and appropriately—especially with men

* Mothers and daughters generally know each other better and spend more time together throughout their lives than fathers and daughters.

* Too many daughters regret not having gotten to know their father very well while he was still alive.

* Our society emphasizes the importance of mother-daughter relationships more than father-daughter relationships.

* Most children’s books, TV programs, and movies send the message that fathers and daughters are not supposed to know each other as well or spend as much time together as mothers and daughters.

* Daughters who are raised by single fathers are just as well adjusted and as happy as daughters raised by single mothers.

* Fathers and daughters are usually closer when the mother works full time outside the home while the children are growing up.
* The more hours a mother works and the higher her income, the more time the father spends with their children.

* Most fathers want to spend more time with their children, but can’t because of their jobs. Realities: (1) Eighty percent of the fathers in our country earn most of the money for their families. (2) Counting the time spent commuting, working, doing house and yard work, and being with the kids, the average father has 5 hours less free time each week than the average employed mother. (3)On average, employed fathers work 10 more hours a week than employed mothers.

* Many fathers believe that their wives and daughters’ feelings for them are partly—or sometimes largely—based on money.

* A father usually has a closer relationship with his kids when the mother lets everyone in the family know how much she appreciates his ways of parenting—especially if his way of relating to the kids isn’t exactly like hers.

* A daughter has a better relationship with her father when her mother does not rely on her for advice or comfort on adult issues—especially issues involving the parents’ relationship with each other.

* When parents are unhappily married, most children side with their mother against their father.

* Sadly, there are mothers who feel uncomfortable or jealous with the idea that their daughter might share as much time or as much personal information with her father as she does with her mother.

Angln

Modern Angeln, also known as Anglia (German and English: Angeln, Danish: Angel, Latin: Anglia), is a peninsula in Southern Schleswig in the northern Schleswig-Holstein, Germany, protruding into the Bay of Kiel. It is separated from the neighbouring peninsula of Schwansen (Danish: Svans or Svansø) by the Schlei inlet, and from the Danish island of Als by the Flensburger Förde ("Firth of Flensburg"). Whether ancient Angeln conformed to these borders is uncertain. It may have been somewhat larger; however, the ancient sources mainly concur that it included the territory of modern Angeln.

Angeln has a significance far beyond its current small area and country terrain, in that it is believed to have been the original home of the Angles, Germanic immigrants to central and northern England, and East Anglia. This migration led to their new homeland being named after them, from which the name "England" derives. Both England and the English language thus ultimately derive their names from the Angles and Angeln.

Name

In one theory the name of the Angles came from Germanic words for "narrow" (compare German eng = "narrow"), and meant "the people who live beside the Narrow [Water]", i.e. beside the Schlei estuary. The root would be *angh-, "tight".



The word Engel in German means "Angles", but is used as a way to designate the area they occupied (Anglia). The most common theory is that the name Angeln itself etymologically means "hook", as in angling for fish. Many reputable etymological dictionaries are silent on its root. Julius Pokorny, a major Indo-European linguist, derives it from *ang-, "bend". The meaning would be Anwohner der Holsteiner Bucht, "residents at the Bay of Holstein". The problem with this derivation is that Grimm's Law does not appear to apply to it. The theory that "Angeln" refers to a landform resembling a hook would have required advanced mapmaking abilities by its people, and is thus misleading.[citation needed]







The town of Schleswig on the Schlei



Angeln is situated on the large bight linking the Baltic coast to Jutland, which is mainly the Bay of Kiel (Kieler Bucht), but might be seen as Holsteiner Bucht.



The Angles were part of the Federation of the Ingaevones, with their mythyical ancestor and god of fertility Yngvi, and both terms might well share the same root (inglish -> anglish), say as the origin of the federation. Pokorny points out the possible use of this etymological root in other ancient names, such as Hardanger and Angrivarii.



[edit] Early history


The region was home to the Germanic people, the Angles, who, together with Saxons and Jutes, left their home to migrate to Britain in the 5th-6th centuries. For the years 449-455, the Anglo-Saxon Chronicle, ca. 890 A.D., describes how King Vortigern (a British tribal king) invited the Angles to come and receive land in return for helping him defend against marauding Picts. Those successful Angles sent word back that good land was available and that the British were worthless (presumably as soldiers). A wholesale emigration of Angles and kindred German peoples followed.



The Chronicle, commissioned by King Alfred the Great, drew on earlier oral traditions and on the few written fragments available. The best of these, written around 730 A.D., was by the monk Bede whose history of English Christianity had the following brief account of Anglo origins:



"...from the Angles, that is, the country which is called Anglia, and which is said, from that time, to remain desert to this day, between the provinces of the Jutes and the Saxons, are descended the East Angles, the Midland Angles, Mercians, all the race of the Northumbrians, that is, of those nations that dwell on the north side of the river Humber, and the other nations of the English." (Bede's Ecclesiastical History of the English Nation, Book I, Chapter XV, 731 A.D.)


The phrase "north of the Humber" refers to the northern kingdom of Northumbria which includes what is now north and north-eastern England and part of southern Scotland. Mercia was located in central England and broadly corresponds to what is now known as the English Midlands.



It had long been suspected from all the Germanic sources that this report is too simple, a suspicion confirmed by the archaeology; namely, the fibulae, or brooches, worn by the women. There are essentially two kinds, the saucer brooch and the cruciform brooch. East coastal and northern Britain were settled by women wearing cruciform brooches, which came from coastal Scandinavia, all of Denmark, and Schleswig-Holstein all the way south to the lower Elbe and all the way east to the Oder, as well as a pocket in coastal Friesland, the embarkation point.


South central Britain was settled by women wearing the saucer brooch, which came from Lower Saxony, the south side of the lower Elbe, and pockets among the then Franks up the Rhine and along the coast to the mouth of the Seine.



Eastern Sweden, except in the far north, did not use either brooch, which may indicate that they were not as close culturally to the westward-looking population; i.e., they formed a conservative subculture of their own, the nucleus of a future Sweden. They would have looked adventurously rather to the east, where the Goths had gone and where the Vikings who would found Russia were to go.


The most logical conclusion is that the "Angles" were the people who populated all of Schleswig-Holstein and Western Pomerania south to the first big bend in the Elbe. They must have included identities mentioned under other names in the more ancient sources, just as the Angles themselves must have had other names. A more complete presentation is given under Angles.



[edit] Later history






The Isted Lion, Berlin copy.



After the Angles departed from Anglia, by the 8th century the region was occupied by Danish Vikings. This is reflected in the large number of place names ending in -by (meaning -village) in the region today. In the Viking period, the chronicler Æthelweard reports that the most important town in Angeln was Hedeby.



Later Angeln's history is subsumed in that of the larger surrounding region, which came to be known as Southern Jutland or Schleswig (Danish: Slesvig). Until the 19th century, the area primarily belonged to Denmark. But ethnically and linguistically a mixed German/Danish population evolved. Denmark lost Schleswig to Austria and Prussia in 1864 as a result of the second war of Schleswig. In 1920, following Germany's defeat in World War I, a plebiscite was held to determine which areas should return to Danish control. As a result of the plebiscite, much of Schleswig returned to Denmark, but Angeln remained in Germany. See Schleswig-Holstein Question for a detailed history.

The Angles is a modern English word for a Germanic-speaking people who took their name from the ancestral cultural region of Angeln, a district located in Schleswig-Holstein, Germany. The Angles were one of the main groups that settled in Britain in the post-Roman period, founding several of the kingdoms of Anglo-Saxon England, and their name is the root of the name "England".

[edit] Etymology

The ethnic name "Angle" has had various forms and spellings, the earliest attested being the Latinized name Anglii, a Germanic tribe mentioned in the Germania of Tacitus.

The original noun from which this adjective was produced has not been determined with confidence. The stem is theorized to have had the form *Ang?l/r-. The more prominent etymological theories concerning the name's origin have included:

* Derivation from the Latin word angulus, translating as "angle".
* The Old English word for the Baltic district of Angeln (where the Angles are believed to have emigrated from) is Angel. This is the preferred etymological theory amongst historians, and may connect to Angle (the peninsula is noted for its "angular" shape).
* It may mean "the people who dwell by the Narrow Water," (i.e. the Schlei), from the Proto-Indo-European language root ang- meaning "narrow".
* Derivation from the Germanic god Ingwaz or the Ingvaeones federation of which the Angles were part (the initial vowel could as well be "a" or "e").

Pope Gregory the Great is the first known to have simplified Anglii to Angli, which he did in an epistle, the latter form developing into the preferred form of the word in Britain and throughout the continent (the generic form becoming Anglus in answer). The country remained Anglia in Latin. Meanwhile, there are several likenesses of form and meaning attested in Old English literature: King Alfred's (Alfred the Great) translation of Orosius' history of the world uses Angelcynn (-kin) to describe England and the English people; Bede used Angelfolc (-folk); there are also such forms as Engel, Englan (the people), Englaland, and Englisc, all showing signs of vocalic mutation and later developing into the dominant forms.

Angle is used as the root of the French and Anglo-Norman words Angleterre (Angleland, i.e. England) and anglais (English).
[edit] Early history
[edit] Angles under other names

Two important geographers, Strabo and Pliny, are silent concerning the Angles. Their reasons for this exclusion was their consideration of the south shore of the Baltic to be terra incognita, "unknown land." However, both Strabo and Pliny describe that shore. Since the Angles took a geographic name, they likely had other names not based on geography.

Strabo's mention of the Battle of Teutoburg Forest places his knowledge in the final years of Augustus' reign and after, which is the early first century. Strabo (7.2.1, 4 and 7.3.1) states that the Cimbri still live on the peninsula (Jutland) where they always did, even though some of them liked to wander. Beyond the Elbe the coastal people are unknown in Strabo's work, but south of them are the Suebi from the Elbe to the Getae (Goths). Strabo worked eastward from the Rhine.

Pliny, on the other hand, worked from east to west (4.13.94). His description leaves the Black Sea, crosses the Ripaei mountains to the shore of the northern ocean, and follows it westward to Cadiz. In the first direction is Scythia, where the Sarmati, Venedi, Sciri, and Hirri are located, as far as the Vistula. Then the Inguaeones begin. Baunonia (Bornholm) is an island opposite Scythia. Cylipenus, probably the Bay of Kiel, is described, and from there a gulf called Lagnus, which is on the frontier of the Cimbri. Its location is not known, but it was likely in the Angeln region.

In Pliny, the Inguaeones consisted of the Cimbri and the Teutones (the Chauci as well, but they were not in this region). If Lagnus was situated on the Cimbrian frontier and after Kiel, then Angeln must have been in the territory of the Teutones. They were perhaps not named "Angles" at that time; however, the territory of the Teutones probably included the Vorpommern and the region south to the Elbe (mainly Holstein), accounting for the implied larger range of the Angles in later sources.
[edit] Tacitus
The map shows both the Angeln peninsula (to the east of Flensburg and Schleswig) and the Schwansen peninsula (south of the Schlei).

Possibly the first instance of the Angles in recorded history is in Tacitus' Germania, chapter 40, in which the "Anglii" are mentioned in passing in a list of Germanic tribes. He gives no precise indication of their geographical situation but states that, together with six other tribes, they worshiped a goddess named Nerthus, whose sanctuary was located on "an island in the Ocean". The other tribes are the Reudigni, Aviones, Varini, Eudoses, Suarini and Nuitones[1], which together are described as being behind ramparts of rivers and woods[2], i.e., inaccessible to attack. As the Eudoses are the Jutes, these names probably refer to localities in Jutland or on the Baltic coast, in which case their inhabitants would be Cimbri or Teutones for Pliny. The coast contains sufficient estuaries, inlets, rivers, islands, swamps and marshes to have been then inaccessible to those not familiar with the terrain, such as the Romans, who considered it unknown and inaccessible country.

The majority of scholars believe that the Anglii lived on the coasts of the Baltic Sea, probably in the southern part of the Jutish peninsula. This view is based partly on Old English and Danish traditions regarding persons and events of the 4th century, and partly on the fact that striking affinities to the cult of Nerthus as described by Tacitus are to be found in pre-Christian Scandinavian, especially Swedish and Danish, religion.

Investigations in this subject have rendered it very probable that the island of Nerthus was Sjælland (Zealand). The kings of Wessex traced their ancestry to a certain Scyld, who is clearly to be identified with Skiöldr, the mythical founder of the Danish royal family (Skiöldungar). In English tradition this person is connected with "Scedeland" (pl.), i.e. Scandinavia, while in Scandinavian tradition he is associated with the ancient royal residence at Lejre in Sjælland.

The account in Germania is inconsistent with Strabo's and Pliny's on a major point. Tacitus called the Baltic the Suebian Sea and viewed the seven tribes that included the Anglii as Suebi. For Pliny the Suebi were among the tribes of Herminones in central Germany. For Strabo, the Suebi were to the south of the coast. The Suebian language developed into Old High German, while the Angles and Jutes were among the speakers of Old Saxon.
[edit] Suevi Angili

Ptolemy in his Geography (2.10), half a century later, presents a somewhat more complex view. The Saxons are placed around the lower Elbe, which area they could have reached merely by an extension of the Saxon alliance. East of them are the Teutones and also a dissimilation of them, the Teutonoari, which denotes "men" (wer); i.e., "the Teuton men." These Teutons or Teuton men appear to have been in Angeln and the land around it.

The Angles, as such, are not listed at all. Instead there are Syeboi Angeilloi, Latinized to Suevi Angili, located south of the middle Elbe. Owing to the uncertainty of this passage, there has been much speculation regarding the original home of the Anglii. One theory is that they dwelt in the basin of the Saale (in the neighbourhood of the canton Engilin), from which region the Lex Angliorum et Werinorum hoc est Thuringorum is believed by many to have come.

A second possible solution is that these Angles of Ptolemy are not those of Schleswig at all. According to Julius Pokorny the Angri- in Angrivarii, the -angr in Hardanger and the Angl- in Anglii all come from the same root meaning "bend", but in different senses. In other words, the similarity of the names is strictly coincidental and does not reflect any ethnic unity beyond Germanic. The Suevi Angeli would have been in Lower Saxony or near it and, like Ptolemy's Suevi Semnones, were among the Suebi at the time.
[edit] Bede
Manuscript of Bede.

Bede states that the Anglii, before coming to Great Britain, dwelt in a land called Angulus, and similar evidence is given by the Historia Brittonum. King Alfred the Great and the chronicler Æthelweard identified this place with the district that is now called Angeln, in the province of Schleswig (Slesvig) (though it may then have been of greater extent), and this identification agrees with the indications given by Bede. Confirmation is afforded by English and Danish traditions relating to two kings named Wermund and Offa, from whom the Mercian royal family were descended and whose exploits are connected with Angeln, Schleswig, and Rendsburg. Danish tradition has preserved record of two governors of Schleswig, father and son, in their service, Frowinus (Freawine) and Wigo (Wig), from whom the royal family of Wessex claimed descent. During the 5th century, the Anglii invaded Great Britain, after which time their name does not recur on the continent except in the title of Suevi Angili.

The province of Schleswig has proved rich in prehistoric antiquities that date apparently from the 4th and 5th centuries A.D. A broad cremation cemetery has been found at Borgstedterfeld, between Rendsburg and Eckernförde, and it has yielded many urns and brooches closely resembling those found in heathen graves in England. Of still greater importance are the great deposits at Thorsberg moor (in Angeln) and Nydam, which contained large quantities of arms, ornaments, articles of clothing, agricultural implements, etc., and in Nydam even ships. By the help of these discoveries, Angle civilization in the age preceding the invasion of Great Britain can be fitted together.
[edit] Angle kingdoms in England
See also: History of Anglo-Saxon England
Angles and Saxons throughout England

According to sources such as the History of Bede, after the invasion of Great Britain, the Angles split up and founded the kingdoms of the Nord Angelnen (Northumbria), Ost Angelnen (East Anglia), and the Mittlere Angelnen (Mercia). In early times there were two northern kingdoms (Bernicia and Deira) and two midland ones (Middle Anglia and Mercia). As a result of influence from the West Saxons, the tribes were collectively called Anglo-Saxons by the Normans, the West Saxon kingdom having conquered, united and founded the Kingdom of England by the 10th century. The regions of East Anglia and Northumbria are still known by their original titles to this day. Northumbria once stretched as far north as what is now southeast Scotland, including Edinburgh, and as far south as the Humber Estuary.

The rest of that people stayed at the centre of the Angle homeland in the northeastern portion of the modern German Bundesland of Schleswig-Holstein, on the Jutland Peninsula. There, a small peninsular area is still called "Angeln" today and is formed as a triangle drawn roughly from modern Flensburg on the Flensburger Fjord to the City of Schleswig and then to Maasholm, on the Schlei inlet.
[edit] St. Gregory

The Angles are the subject of a legend about Pope Gregory I which apparently has roots in history. Gregory happened to see a group of Angle children from Deira for sale as slaves in the Roman market. Gregory inquired about their background. When told they were called "Anglii" (Angles), he replied with a Latin pun that translates well into English: “Bene, nam et angelicam habent faciem, et tales angelorum in caelis decet esse coheredes” ("It is well, for they have an angelic face, and such people ought to be co-heirs of the angels in heaven"). Supposedly, he thereafter resolved to convert their pagan homeland to Christianity.[3]

Top 10 Features Your Next Car Should Have

Top 10 Features Your Next Car Should Have

By Aaron Gold, About.com Guide
Used to be that power windows and locks were the epitomy of luxury. Today they are standard on most econoboxes; technology has gifted us with a great many more goodies and gadgets. Here are ten features and options that will make life with your car a lot easier and safer.
1. Remote keyless entry
Keyless entry systems allow you to unlock your car by pushing a button on a remote. The ability to quickly get into your car without fumbling for the key is an important safety feature, especially in poorly-lit areas. With most remotes, pushing the button once unlocks just the driver's door; you must push twice to unlock other doors, so there's no worry about a hidden intruder jumping into the passenger's side. Most also have a panic button that honks the horn and flashes the lights.
1
2. OnStar System
With OnStar, help from a real-live person is always just a button-push away. Got a flat tire? Someone following you? Just need to hear a human voice? Push the button. OnStar advisors can summon a tow truck or a cop, or just say hello. If your airbags deploy, they call you. They can even track your car if it's stolen and remotely let you in if you're locked out. OnStar charges a monthly subscription fee; the basic plan gives you the most critical safety benefits and is a bargain at $17/month.
2
3. Anti-lock brakes (ABS)
Simple physics dictates that a turning wheel has more traction than one that is skidding. Antilock brake systems (ABS) watch individual wheel speeds; if one locks up, they pump the brakes far faster than a human could. Don't worry about giving up control to a computer; if the ABS system goes on the fritz (they rarely do) the brakes work normally. Do-it-yourselfers can still do their own brake jobs (though you must relieve system pressure before removing a brake line; check your repair manual).
3
4. Electronic stability/skid-control system
ESC systems use the anti-lock brake sensors (which show individual wheel speed), accelerometers, and steering wheel/pedal position sensors to figure out what the car is doing and what the driver wants it to do. If the two don't seem to match up, ESC does what no driver can: It applies the brakes to individual wheels and reduces power as needed to keep the car going where the driver is trying to point it. They are almost transparent and work surprisingly well.
4
5. Telescoping steering wheel/adjustable pedals
Most new cars have height-adjustable (tilt) steering columns; some cars have steering wheels that telescope (move in and out) and/or electrically adjustable pedals. The latter two not only make finding a comfortable position easier, but they allow shorter drivers to safely position themselves farther from the airbag while still keeping their feet comfortably on the pedals.
5
6. Rear-seat DVD player
Got kids? Movies-on-the-go can make long trips easier for both you and them. Many rear-seat entertainment systems include wireless headphones, so you can enjoy the stereo (or the peace and quiet). My own children would have TVs surgically implanted in the backs of their hands if they could, so in order to avoid turning them into road-going zombies I generally limit movie watching to long trips. They also make a convenient reward and/or dangling carrot.
6
7. GPS navigation system
Using the Global Positioning Satellite System and sensors in the car, GPS navigation systems can pinpoint your exact location and give you turn-by-turn directions (via a small video screen, spoken voice, or both) to help you find your way. Most will also guide you to the closest gas station, ATM, hospital or police station. They can steer you out of a bad neighborhood, they can route you around traffic, and no matter how lost you get, they can always help you find your way home.
7
8. Side airbags
Most cars have at least three feet of crush space at the front and back, but only a few inches of protection at the sides. Federally-mandated door beams help keep the car intact instead of caving in. But there's still the problem of inertia: While the car is being pushed away, your body (particularly your head, which isn't secured by the seat belt) wants to stay still, and it could go right through the side window. Side airbags cushion your noggin and help keep it safely inside the car.
8
9. Center console with power outlet
Open the center consoles on many new cars and you'll find a power outlet (a.k.a. a cigarette lighter without the lighter). These outlets provide a way to charge your mobile phone while keeping it out of sight. I'm dead-set against talking on the phone while driving (though I sometimes do it anyway), but it's good to know you'll always have juice to make a call in case of an emergency.
9
10. Roadside assistance
Flat tire? Dead battery? Out of gas? Traditionally, people have turned to AAA (US) or CAA (Canada) for life's little motoring emergencies, but many new cars come with roadside assistance as part of their new-car warranty. Several manufacturers even offer it as part of their "certified used" programs. That said, AAA and CAA memberships are inexpensive; with all the travel discounts they bring, your membership may very likely pay for itself.
