Wikipedia: George Frideric Handel (23 February 1685 - 14 April 1759) -- was a German-British Baroque composer, famous for his operas, oratorios, anthems and organ concertos - After his success with Messiah (1742 A.D.) he never performed an Italian opera a

After his success with Messiah in 1742 A.D. he never performed an Italian opera again. Handel was only partly successful with his performances of English Oratorio on mythical or biblical themes, but when he arranged a performance of Messiah to benefit the Foundling Hospital (1750) the critique ended. The pathos of Handel's oratorio is an ethical one, they are hallowed not by liturgical dignity but by the moral ideals of humanity. Almost blind, and having lived in England for almost fifty years, he died a respected and rich man. -- Handel is regarded as one of the greatest composers of all time, not only because of his Water Music, and Music for the Royal Fireworks. But since the late 1960s, with the revival of baroque music and original instrument interest in Handel's opera seria has revived too. Handel composed forty operas in about thirty years; some are considered as masterpieces, with many sweeping arias and much admired improvisations. His operas contain remarkable human characterization, by a composer not known for his love affairs. -- Messiah: (HWV 56) is an English-language oratorio composed in 1741 by George Frideric Handel, with a scriptural text compiled by Charles Jennens from the King James Bible, and from the Psalms included with the Book of Common Prayer (which are worded slightly differently than their King James counterparts). It was first performed in Dublin on 13 April 1742, and received its London premiere nearly a year later. After an initially modest public reception the oratorio gained in popularity, eventually becoming one of the best-known and most frequently performed choral works in Western music.

St. Irenaeus of Lyons, France (120-203 A.D.) - As a boy he had, as he delighted to point out, listened to the sermons of the great bishop and martyr, Polycarp of Smyrna, who was regarded as a disciple of the Apostles [John and possibly Paul] themselves -

Relatively little is known of the life of Irenaeus. As a boy he had, as he delighted to point out, listened to the sermons of the great bishop and martyr, Polycarp of Smyrna, who was regarded as a disciple of the apostles themselves. Here he came to know, 'the genuine unadulterated gospel', to which he remained faithful throughout his life. Perhaps he also accompanied Polycarp on his journey to Rome in connection with the controversy over the date of celebrating Easter (154 CE). Later he went as a missionary to southern Gaul, where he became a presbyter at Lyons. A Catholic Encyclopedia article is online at St. Irenaeus. Irenaeus was absent from the city when the persecution there reached its zenith. It seems that he had been sent to Rome by the Gallican churches in order to confer with Pope Eleutherus, perhaps as a mediator in the Montanist disputes. Evidently Irenaeus stayed in Rome for just a short time, and soon after the end of the persecution we find him again in Lyons as the successor to Bishop Pothinus (178). When and how he died is unknown to us. Jerome and others state that he died as a martyr in the persecution under the Emperor Septimus Severus (202), but there is no certainty about this tradition. In short, we know Irenaeus almost solely from his writings, and these have not been preserved in their entirety. ... The era in which Irenaeus lived was a time of expansion and inner tensions in the church. In many cases Irenaeus acted as mediator between various contending factions. The churches of Asia Minor (where he was probably born) continued to celebrate Easter on the same date (the 14th of Nisan) as the Jews celebrated Passover, whereas the Roman Church maintained that Easter should always be celebrated on a Sunday (the day of the Resurrection). Mediating between the parties, Irenaeus stated that differences in external factors, such as dates of festivals, need not be so serious as to destroy church unity. Irenaeus adopted a totally negative and unresponsive attitude, however, toward Marcion, a schismatic leader in Rome, and toward the Valentinians, a fashionable intellectual Gnostic movement in the rapidly expanding church that espoused dualism. Because Gnosticism was overcome by the Orthodox Church, Gnostic writings were largely obliterated. In reconstructing Gnostic doctrines, therefore, modern scholars relied to a great extent on the writings of Irenaeus, who summarized the Gnostic views before attacking them. After the discovery of the Gnostic library near Nag Hammadi in Egypt in the 1940s (see Robinson), respect for Irenaeus increased. He was proved to have been extremely precise in his report of the doctrines he rejected. The oldest lists of bishops also were countermeasures against the Gnostics, who said that they possessed a secret oral tradition from Jesus himself. Against such statements Irenaeus maintains that the bishops in different cities are known as far back as the Apostles - and none of them was a Gnostic - and that the bishops provided the only safe guide to the interpretation of the Scriptures. With these lists of bishops the later doctrine of "the apostolic succession" of the bishops could be linked.

Justin Martyr (100-167 A.D.), Philosopher, Apologist, and Martyr (1 June 167 A.D.) - Justin was born around 100 A.D. (both his birth and death dates are approximate) at Flavia Neapolis (ancient Shechem, modern Nablus) in Samaria (the middle portion of Isr

Justin became a Christian, but he continued to wear the cloak that was the characteristic uniform of the professional teacher of philosophy. His position was that pagan philosophy, especially Platonism, is not simply wrong, but is a partial grasp of the truth, and serves as "a schoolmaster to bring us to Christ." He engaged in debates and disputations with non-Christians of all varieties, pagans, Jews, and heretics. He opened a school of Christian philosophy and accepted students, first at Ephesus and then later at Rome. There he engaged the Cynic philosopher Crescens in debate, and soon after was arrested on the charge of practicing an anauthorized religion. (It is suggested that Crescens lost the debate and denounced Justin to the authorities out of spite.) He was tried before the Roman prefect Rusticus, refused to renounce Christianity, and was put to death by beheading along with six of his students, one of them a woman. A record of the trial, probably authentic, is preserved, known as The Acts of Justin the Martyr. ... Justin's works are found in the multi-volumed set called The Ante-nicene Fathers [Church leaders before the Council of Nicea in 325 A.D.], and in various other collections of early Christian writings.

{Basic Christian: blog Bible Study} The Apostle Paul - When Paul became a Christian, his very thorough [Jewish] education was enormously helpful - He was able to assimilate Christian doctrines rapidly and relate them accurately to the Scripture teaching h

The Apostle Paul - The apostle Paul was one of the most famous citizens of the Roman Empire and without question one of the most influential individuals in history. He was used by the Lord in his missionary and evangelistic activities to set in motion a great deal of the organization known as the Christian Church, the Body of Christ on earth, to the extent that billions of human beings have been directly or indirectly affected by his ministry. Under the inspiration of the Holy Spirit, he wrote the foundation documents for the Christian way of life, the Word of God which has changed the lives of millions. -- Paul's Education: Paul was educated by his mother until the age of five. From age five to ten he studied with his father in the Hebrew scriptures and traditional writings. At the same time, being a Roman citizen and living in a Greek and Roman environment, he received a thorough education in the Greek language, history, and culture. He was sent to Jerusalem at about the age of ten to attend the rabbinical school of Gamaliel, who was the son of Simeon the son of Hillel. Gamaliel was a most eminent rabbi who was mentioned both in the Talmud and in the New Testament (Acts 5:24-40; 22:3). Gamaliel was called Rabban - one of only seven teachers so called. He was a Pharisee, but he rose above party prejudice. He composed a prayer against the Christian "heretics". He lived and died a Jew. At this time, Herod was dead, and the Romans had complete control of Judea, hence, there was Roman money, language, and culture. The Jews, therefore, were inclined to cling more closely to their religion as the center of unity. [Refer to the topic: Judean History] There were two great rabbinical schools, those of Hillel and Schammai. Hillel, the grandfather of Gamaliel, held that tradition was superior to the Law. The school of Schammai despised traditionalists, especially when there teachings clashed with the writings of Moses. The religious school of Gamaliel (Hillel) was chiefly oral and usually had a prejudice against any book but Scripture. They used a system of Scriptural exegesis, and Josephus in his writings expressed the wish to have such a power of exegesis. When school was in session, learned men met and discussed scriptures, gave various interpretations, suggested illustrations, and quoted precedents. The students were encouraged to question, doubt, even contradict. -- When Paul became a Christian, his very thorough education was enormously helpful. He was able to assimilate Christian doctrines rapidly and relate them accurately to the Scripture teaching he had received. From his education, both from Gamaliel and in the desert from the Lord Jesus Christ, Paul developed a divine viewpoint attitude toward human history. Paul knew that the existence of God can easily be perceived by anyone, that man can become aware of God, but that many men's deliberate sin halted this good beginning by immoral activities which accompanied their idolatry. Therefore, Paul had an intense hatred of idolatry of any kind. Paul's teaching shows that the only reality is God. Idolatry distorts man's conception of the world and external nature. Idolatry is the enemy of mankind. Paul knew the law of growth of human nature. As a Roman, Tarsian, Hebrew, and culturally Greek, he knew of the many distortions of the life of his society. As a nation becomes unhealthy, development is halted. Societies errors as to the nature of God and the true relation of God to man prevented nations from getting rid of their besetting evil. The books of Acts is the chief authoritative record for the ministries of Paul and the other apostles. For a brief outline of Paul's ministry, see the Chronological Table of Paul's Ministry. The most thorough, accurate, and interesting secular work on Paul is The Life and Epistles of St. Paul, by Conybeare and Howson.

5 Deadly Sins That Can Wreck Your Franchise – and How to Avoid Them

The food and beverage industry is a tough game. Sixty percent of restaurants don’t make it past their first year, and 80 percent go out of business within five years. Those are hard odds.

Franchising takes some of the risks out of the equation by giving you a proven model to work with. But being a franchisor with a proven model under your arm does not mean you’re suddenly bulletproof or immune to the laws of economics. If you start making unforced errors, you are going to fail.

Here are the five reasons most people fail as the owner of a franchise. Avoid these deadly sins at all costs:

Sin 1: Financial complacency
Sin 2: Operational obtuseness
Sin 3: Poor hiring choices
Sin 4: Myopic risk management
Sin 5: Mediocre offerings

The Bio-Chemical Matrix - The Myths of Matrix Science

by Jon Rappoport www.nomorefakenews.com The medical system kills 225,000 people a year. (Starfield, JAMA, July 26, 2000, "Is US health really the best in the world?") "In principle, gene therapy is a medical miracle waiting to happen ... after 17 years of trying, scientists are still struggling to make gene therapy work. Complications include rejection of DNA carriers ... [and] new genes end up where they shouldn't, or behave unpredictably." ("Gene Therapy: Is Death and Acceptable Risk?", Wired, Brandon Keim, August 30, 2007) MARCH 28, 2012 - In discussing Matrix Science, I'm reminded of Philip Dick's sensational novel, Lies, Inc. It proposes an invention that can teleport humans light-years to a planet where a better way of life exists. The author then spends the rest of the book deconstructing this utopian legend and revealing the truth and the titanic power-grab that sit behind it. Then there is HG Well's 1933 classic novel, The Shape of Things to Come, in which a world exhausted by war and economic collapse turns to a Global State as the only possible solution, after all other solutions have historically failed. This new ruling authority is based on Science. All religions are crushed. Education is designed to teach every child how to become a genius/global citizen. Eventually, the State withers away and is of course replaced by a spontaneous Utopia. Science/technology: the final all-encompassing answer. A significant aspect of Matrix propaganda revolves around myths about how human behavior can be transformed. Transformed through advances in biology and chemistry. Populations are being trained to expect these momentous changes. A major selling point: no effort is required. Just ingest this tablet. Accept this new gene. All will be done for you by experts. Technocrats will design the future so you will fit into it happily. The technocratic wing of Globalism has clout. It promises management of the planet through science, and who can argue with science? Central Planning will ensure proper benefits for all. My late friend and colleague, hypnotherapist Jack True, once told me in an interview:...

"...you just get used to them"

“Young man, in mathematics you don’t understand things, you just get used to them.” —John von Neumann1

This, in a sense, is at the heart of why mathematics is so hard. Math is all about abstraction, about generalizing the stuff you can get a sense of to apply to crazy situations about which you otherwise have no insight whatsoever. Take, for example, one way of understanding the manifold structure on SO(3), the special orthogonal group on 3-space. In order to explain what I’m talking about, I’ll have to give several definitions and explanations and each, to a greater or lesser extent, illustrates both my point about abstraction and von Neumann’s point about getting used to things.

First off, SO(3) has a purely algebraic definition as the set of all real (that is to say, the entries are real numbers) 3 × 3 matrices A with the property ATA = I and the determinant of A is 1. That is, if you take A and flip rows and columns, you get the transpose of A, denoted AT; if you then multiply this transpose by A, you get the identity matrix I. The determinant has its own complicated algebraic definition (the unique alternating, multilinear functional…), but it’s easy to compute for small matrices and can be intuitively understood as a measure of how much the matrix “stretches” vectors. Now, as with all algebraic definitions, this is a bit abstruse; also, as is unfortunately all too common in mathematics, I’ve presented all the material slightly backwards.

This is natural, because it seems obvious that the first thing to do in any explication is to define what you’re talking about, but, in reality, the best thing to do in almost every case is to first explain what the things you’re talking about (in this case, special orthogonal matrices) really are and why we should care about them, and only then give the technical definition. In this case, special orthogonal matrices are “really” the set of all rotations of plain ol’ 3 dimensional space that leave the origin fixed (another way to think of this is as the set of linear transformations that preserve length and orientation; if I apply a special orthogonal transformation to you, you’ll still be the same height and width and you won’t have been flipped into a “mirror image”). Obviously, this is a handy thing to have a grasp on and this is why we care about special orthogonal matrices. In order to deal with such things rigorously it’s important to have the algebraic definition, but as far as understanding goes, you need to have the picture of rotations of 3 space in your head.

Okay, so I’ve explained part of the sentence in the first paragraph where I started throwing around arcane terminology, but there’s a bit more to clear up; specifically, what the hell is a “manifold”, anyway? Well, in this case I’m talking about differentiable (as opposed to topological) manifolds, but I don’t imagine that explanation helps. In order to understand what a manifold is, it’s very important to have the right picture in your head, because the technical definition is about ten times worse than the special orthogonal definition, but the basic idea is probably even simpler. The intuitive picture is that of a smooth surface. For example, the surface of a sphere is a nice 2-dimensional manifold. So is the surface of a donut, or a saddle, or an idealized version of the rolling hills of your favorite pastoral scene. Slightly more abstractly, think of a rubber sheet stretched and twisted into any configuration you like so long as there are no holes, tears, creases, black holes or sharp corners.

In order to rigorize this idea, the important thing to notice about all these surfaces is that, if you’re a small enough ant living on one of these surfaces, it looks indistinguishable from a flat plane. This is something we can all immediately understand, given that we live on an oblate spheroid that, because it’s so much bigger than we are, looks flat to us. In fact, this is very nearly the precise definition of a manifold, which basically says that a manifold is a topological space (read: set of points with some important, but largely technical, properties) where, at any point in the space, there is some neighborhood that looks identical to “flat” euclidean space; a 2-dimensional manifold is one that looks locally like a plane, a 3-dimensional manifold is one that looks locally like normal 3-dimensional space, a 4-dimensional manifold is one that looks locally like normal 4-dimensional space, and so on.

In fact, these spaces look so much like normal space that we can do calculus on them, which is why the subject concerned with manifolds is called “differential geometry”. Again, the reason why we would want to do calculus on spaces that look a lot like normal space but aren’t is obvious: if we live on a sphere (as we basically do), we’d like to be able to figure out how to, e.g., minimize our distance travelled (and, thereby, fuel consumed and time spent in transit) when flying from Denver to London, which is the sort of thing for which calculus is an excellent tool that gives good answers; unfortunately, since the Earth isn’t flat, we can’t use regular old freshman calculus.2 As it turns out, there are all kinds of applications of this stuff, from relatively simple engineering to theoretical physics.

So, anyway, the point is that manifolds look, at least locally, like plain vanilla euclidean space. Of course, even the notion of “plain vanilla euclidean space” is an abstraction beyond what we can really visualize for dimensions higher than three, but this is exactly the sort of thing von Neumann was talking about: you can’t really visualize 10 dimensional space, but you “know” that it looks pretty much like regular 3 dimensional space with 7 more axes thrown in at, to quote Douglas Adams, “right angles to reality”.

Okay, so the claim is that SO(3), our set of special orthogonal matrices, is a 3-dimensional manifold. On the face of it, it might be surprising that the set of rotations of three space should itself look anything like three space. On the other hand, this sort of makes sense: consider a single vector (say of unit length, though it doesn’t really matter) based at the origin and then apply every possible rotation to it. This will give us a set of vectors based at the origin, all of length 1 and pointing any which way you please. In fact, if you look just at the heads of all the vectors, you’re just talking about a sphere of radius 1 centered at the origin. So, in a sense, the special orthognal matrices look like a sphere. This is both right and wrong; the special orthogonal matrices do look a lot like a sphere, but like a 3-sphere (that is, a sphere living in four dimensions), not a 2-sphere (i.e., what we usually call a “sphere”).

In fact, locally SO(3) looks almost exactly like a 3-sphere; globally, however, it’s a different story. In fact, SO(3) looks globally like , which requires one more excursion into the realm of abstraction. , or real projective 3-space, is an abstract space where we’ve taken regular 3-space and added a “plane at infinity”. This sounds slightly wacky, but it’s a generalization of what’s called the projective plane, which is basically the same thing but in a lower dimension. To get the projective plane, we add a “line at infinity” rather than a plane, and the space has this funny property that if you walk through the line at infinity, you get flipped into your mirror image; if you were right-handed, you come out the other side left-handed (and on the “other end” of the plane). But not to worry, if you walk across the infinity line again, you get flipped back to normal.

Okay, sounds interesting, but how do we visualize such a thing? Well, the “line at infinity” thing is good, but infinity is pretty hard to visualize, too. Instead we think about twisting the sphere in a funny way:

You can construct the projective plane as follows: take a sphere. Imagine taking a point on the sphere, and its antipodal point, and pulling them together to meet somewhere inside the sphere. Now do it with another pair of points, but make sure they meet somewhere else. Do this with every single point on the sphere, each point and its antipodal point meeting each other but meeting no other points. It’s a weird, collapsed sphere that can’t properly live in three dimensions, but I imagine it as looking a bit like a seashell, all curled up on itself. And pink.

This gives you the real projective plane, . If you do the same thing, but with a 3-sphere (again, remember that this is the sphere living in four dimensions), you get . Of course, you can’t even really visualize or, for that matter, a 3-sphere, so really visualizing is going to be out of the question, but we have a pretty good idea, at least by analogy, of what it is. This is, as von Neumann indicates, one of those things you “just get used to”.

Now, as it turns out, if you do the math, SO(3) and look the same in a very precise sense (specifically, they’re diffeomorphic). On the face of it, of course, this is patently absurd, but if you have the right picture in mind, this is the sort of thing you might have guessed. The basic idea behind the proof linked above is that we can visualize 3-space as living inside 4-space (where it makes sense to talk about multiplication); here, a rotation (remember, that’s all the special orthogonal matrices/transformations really are) is just like conjugating by a point on the sphere. And certainly conjugating by a point is the same as conjugating by its antipodal point, since the minus signs will cancel eachother in the latter case. But this is exactly how we visualized , as the points on the sphere with antipodal points identified!

I’m guessing that most of the above doesn’t make a whole lot of sense, but I would urge you to heed von Neumann’s advice: don’t necessarily try to “understand” it so much as just to “get used to it”; the understanding can only come after you’ve gotten used to the concepts and, most importantly, the pictures. Which was really, I suspect, von Neumann’s point, anyway: of course we can understand things in mathematics, but we can only understand them after we suspend our disbelief and allow ourselves to get used to them. And, of course, make good pictures.


1 This, by the way, is my second-favorite math quote of the year, behind my complex analysis professor’s imprecation, right before discussing poles vs. essential singularities, to “distinguish problems that are real but not serious from those that are really serious.”

2 As a side note, calculus itself is a prime example of mathematical abstraction. The problem with the world is that most of the stuff in it isn’t straight. If it were, we could have basically stopped after the Greeks figured out a fair amount of geometry. And, even worse, not only is non-straight stuff (like, for example, a graph of the position of a falling rock plotted against time) all over the place, but it’s hard to get a handle on. So, instead of just giving up and going home, we approximate the curvy stuff in the world with straight lines, which we have a good grasp of. As long as we’re dealing with stuff that’s curvy (rather than, say, broken into pieces) this actually works out pretty well and, once you get used to it all, it’s easy to forget what the whole point was, anyway (this, I suspect, is the main reason calculus instruction is so uniformly bad; approximating curvy stuff with straight lines works so well that those who who are supposed to teach the process lose sight of what’s really going on).
