Once the aircraft hits the speed of sound, the interaction changes instantaneously, resulting in a shock wave. For about a quarter of a century, researchers believed that the heliosphere moved through the interstellar medium at a speed fast enough to form a bow shock. For nearly a quarter of a century, scientists believed a ‘bow shock’ formed a sheath around our solar system, between the point where the solar wind ends and intergalactic space begins The discovery, by the agency’s Interstellar Boundary Explorer IBEX ship, gives the most complete glimpse yet of what lies beyond our solar system Another influence is the magnetic pressure in the interstellar medium. IBEX data, as well as earlier Voyager observations, show that the magnetic field is stronger in the interstellar medium requiring even faster speeds to produce a bow shock. Combined, both factors now point to the conclusion that a bow shock is highly unlikely. The IBEX team combined its data with analytical calculations and modeling and simulations to determine the conditions necessary for creating a bow shock. Two independent global models — one from a group in Huntsville, Ala.

Outerlimits 42: Powerboat Performance Report

Powerboat Performance Report Outerlimits Hot offshore V-bottom is lighter and tougher. By Staff April 20, Outerlimits has made a reputation for itself in its 10 years in business as the purveyor of fine custom V-bottoms. If you can imagine it, Mike Fiore and his team of craftsman can probably incorporate it into your boat. Now, with the purchase of a new facility in Bristol, R. No, the boats don’t look different from vinylester boats, which the company still builds, but they are much stronger, and more significant—lighter.

A radioactive isotope decays away at a steady rate defined by its “half-life,” the time it takes half of the substance to turn into a lighter product.

The Radiometric Dating Game Radiometric dating methods estimate the age of rocks using calculations based on the decay rates of radioactive elements such as uranium, strontium, and potassium. On the surface, radiometric dating methods appear to give powerful support to the statement that life has existed on the earth for hundreds of millions, even billions, of years. We are told that these methods are accurate to a few percent, and that there are many different methods. We are told that of all the radiometric dates that are measured, only a few percent are anomalous.

This gives us the impression that all but a small percentage of the dates computed by radiometric methods agree with the assumed ages of the rocks in which they are found, and that all of these various methods almost always give ages that agree with each other to within a few percentage points. Since there doesn’t seem to be any systematic error that could cause so many methods to agree with each other so often, it seems that there is no other rational conclusion than to accept these dates as accurate.

However, this causes a problem for those who believe based on the Bible that life has only existed on the earth for a few thousand years, since fossils are found in rocks that are dated to be over million years old by radiometric methods, and some fossils are found in rocks that are dated to be billions of years old. If these dates are correct, this calls the Biblical account of a recent creation of life into question. After study and discussion of this question, I now believe that the claimed accuracy of radiometric dating methods is a result of a great misunderstanding of the data, and that the various methods hardly ever agree with each other, and often do not agree with the assumed ages of the rocks in which they are found.

I believe that there is a great need for this information to be made known, so I am making this article available in the hopes that it will enlighten others who are considering these questions. Even the creationist accounts that I have read do not adequately treat these issues.

Do not attempt to adjust the picture. We are now controlling the transmission. We control the horizontal and the vertical. We can deluge you with a thousand channels, or expand one single image to crystal clarity

Parting track’d by arriving, perpetual payment of perpetual loan, Rich showering rain, and recompense richer afterward.

Combine all ingredients in saucepan. Bring to boil over medium heat, stirring occasionally to desired consistency. Use as a glaze to baste ham, chicken, fish or vegetables, or serve as a sauce. For hundreds of years, most ships sailed blind when in the area, depending on navigation skills to get though the rough waters. One of the first acts of the fledgling Continental Congress was to authorize light houses and lifesaving stations along the Atlantic Coast from Maine to Florida.

Congress authorized the first lighthouse in on Cape Hatteras overlooking the Diamond Shoals. At that time, Hatteras Inlet was the only deep channel that remained open along the island chain. The structure was ineffective because it was too low and the light very weak. It was replaced in with the present structure, feet tall and a stronger light. The present light can be seen up to 20 miles and by airline pilots as far away as miles. A ft wooden tower was built at the entrance to Ocracoke Island in to house a light but Ocracoke Inlet constantly shifted, rendering it obsolete.


Robert Walker In case you haven’t heard of it, Nibiru is a totally nuts idea. Yet it gets many people very scared. I started to get messages about it as a result of writing articles about asteroid impacts, and how we can detect and deflect asteroids.

Recombination lines are caused when atoms in a nebula are ionized by absorbing energy from the ultraviolet light radiated by a nearby or embedded hot star.

Monday, 28 April The record was sanctioned, recorded and verified by the American Power Boat Association. The canopied SV 43 offshore raceboat’s two-way record was produced by an average speed of Per APBA kilo-run rules, the runs happened within 15 minutes of one another. So we’re going to come back tomorrow morning.

To build on today’s success. At present, the plan is for the boat to head back out on the course early tomorrow morning with its broken prop replaced. The Outerlimits crew will—in essence—be attempting to break its own new record.

How could the universe expand faster than the speed of light? That seems impossible!

Sorry about the aggressive title. Also, thank you for taking the time to read this during work. So the purpose, the essence, of this blog, is that my eharmony subscription is ending this month. This is my second stint on eharmony. Two dates where I was probably settling, compromising and giving in, just to go on dates.

It gives strong constraints on a Jupiter or Saturn sized object.

History of Technology Heroes and Villains – A little light reading Here you will find a brief history of technology. Initially inspired by the development of batteries, it covers technology in general and includes some interesting little known, or long forgotten, facts as well as a few myths about the development of technology, the science behind it, the context in which it occurred and the deeds of the many personalities, eccentrics and charlatans involved.

You may find the Search Engine , the Technology Timeline or the Hall of Fame quicker if you are looking for something or somebody in particular. Scroll down and see what treasures you can discover. Background We think of a battery today as a source of portable power, but it is no exaggeration to say that the battery is one of the most important inventions in the history of mankind. Volta’s pile was at first a technical curiosity but this new electrochemical phenomenon very quickly opened the door to new branches of both physics and chemistry and a myriad of discoveries, inventions and applications.

The electronics, computers and communications industries, power engineering and much of the chemical industry of today were founded on discoveries made possible by the battery. Pioneers It is often overlooked that throughout the nineteenth century, most of the electrical experimenters, inventors and engineers who made these advances possible had to make their own batteries before they could start their investigations.

They did not have the benefit of cheap, off the shelf, mass produced batteries. For many years the telegraph, and later the telephone, industries were the only consumers of batteries in modest volumes and it wasn’t until the twentieth century that new applications created the demand that made the battery a commodity item. In recent years batteries have changed out of all recognition. No longer are they simple electrochemical cells.

Today the cells are components in battery systems, incorporating electronics and software, power management and control systems, monitoring and protection circuits, communications interfaces and thermal management. At the end of the fourth millennium B.

Visual spectrum This site, closely coupled to The Natures of the Stars and The Hertzsprung- Russell HR Diagram , provides an introduction to the spectra of stars and allied celestial objects. Here we examine the principal way in which astronomers have learned so much about the stars. Spectra has been translated into Romanian. The visual spectrum Pass sunlight through a triangular prism or bounce it off the finely grooved surface of a compact audio disk and see it break merrily into a band of pure sparkling color, its “spectrum,” familiar in the colors of a rainbow, in light glittering from newly fallen snow, in the rings and haloes around a partly- clouded Sun and Moon, in the flash of a cut diamond, and in so many other facets of nature.

The classic colors red, orange, yellow, green, blue, and violet connect in a seemingly infinite number of shades, one blending smoothly into the next.

It’s the responsibility of the geologist to show that such mixings have not occurred.

It theorizes that a large quantity of nothing decided to pack tightly together, and then exploded outward into hydrogen and helium. This gas is said to have flowed outward through frictionless space to eventually form stars, galaxies, planets, and moons. It all sounds so simple, just as you would find in a science fiction novel. And that is all it is. Here are a number of reasons why the Big Bang theory not only is obviously incorrect, but totally impossible. It stands In clear violation of physical laws, celestial mechanics, and common sense:

Speed Dating Rules By: Kay Ireland Speed dating may sound silly to some, but in fact, it can be a successful way to meet new people and garner prospective dates. The pace in speed dating still gives you time for a nice connection.

When heated over a flame the steam from the boiling water escaped through two tangential nozzles in jets which caused the sphere to rotate at high speed.

I celebrate myself, and sing myself, And what I assume you shall assume, For every atom belonging to me as good belongs to you. I loafe and invite my soul, I lean and loafe at my ease observing a spear of summer grass. My tongue, every atom of my blood, form’d from this soil, this air, Born here of parents born here from parents the same, and their parents the same, I, now thirty-seven years old in perfect health begin, Hoping to cease not till death.

Creeds and schools in abeyance, Retiring back a while sufficed at what they are, but never forgotten, I harbor for good or bad, I permit to speak at every hazard, Nature without check with original energy. The atmosphere is not a perfume, it has no taste of the distillation, it is odorless, It is for my mouth forever, I am in love with it, I will go to the bank by the wood and become undisguised and naked, I am mad for it to be in contact with me.

Have you reckon’d a thousand acres much? Have you practis’d so long to learn to read? Have you felt so proud to get at the meaning of poems? Stop this day and night with me and you shall possess the origin of all poems, You shall possess the good of the earth and sun, there are millions of suns left, You shall no longer take things at second or third hand, nor look through the eyes of the dead, nor feed on the spectres in books, You shall not look through my eyes either, nor take things from me, You shall listen to all sides and filter them from your self.

There was never any more inception than there is now, Nor any more youth or age than there is now, And will never be any more perfection than there is now, Nor any more heaven or hell than there is now.

Rollerblading Welcome to Drop In Skate! Welcome to my website where we discuss all things skates. Different Kinds of Skates Within the world of ice skates alone there are several types of skates that are all designed for their own unique purposes. The hockey skate is designed to provide power for cornering, hits, and all the other many demands of ice hockey. In contrast, a skate designed for something like figure skating is going to have an altogether different design that has an emphasis on fine control, stationary techniques, and high-flying manoeuvers.

Song of Myself

Even more than The Power of Friendship , the Power of Love can be applied in dire situations to make things better. In fact, in many Disney movies it’s the solution to everything. It’s also an occasionally useful Deus ex Machina. Common applications of the Power of Love include activating an Empathic Weapon , freeing a loved one from mind control , strengthening a loved one , and converting a Real Death into a Disney Death.

Even when the power of love is not literally and directly responsible, the scene is often set such that the audience is left with the impression that it was “really responsible”.

Two species of rare butterflies, the northern Hairstreeak and giant Swallowtail as well as the Messalina Underwind moth are also found in the area.

What existed before the Big Bang? All comments are moderated, your comment will not appear on the site until it has been approved. Joshua Romero, thanks for your article. I think it clears up a lot of confusion, at least in my mind, by emphasizing that the distinction between motion and expansion must be appreciated. WWJ , April 27, at 5: I dont believe you can ever, ever get an effect before the cause. And thanks for pointing that out to me. But if effect before cause seems illogical to you, that means your perspective on things are about what things seems, and not what they are.

Am more about what is, not what seems like. Alot of stories can be concocted by what seems like just like in science fiction.
