Did Gold Fall From Outer Space?
Ever wondered where gold comes from, what inspired mankind's fascination with the shiny precious metal and where the next gold rush may be found?

Since a vertical fall was too fast for Galileo to measure accurately, he slowed it down by making the ball roll down an inclined board. Across the board, along to its surface, he strung a number of taut horizontal wires, making the ball sound a click whenever it jumped over one of them.

Timeline for the fall of the Dragon
Tomorrow morning, Thursday May 31, the SpaceX Dragon capsule will undock from the International Space Station, perform a series of maneuvers, and then come back home to Earth.

Sunspots and the Rise and Fall of Civilizations Maurice Cottrell
There appears to be a correlation between the rise and fall of civilizations with the rise and fall of radiation from the sun. The graph shows a long-term envelope of sunspot activity derived from the center graph of Carbon 14.

~ - Meteorite seen to ~. Such meteorites are usually collected soon after falling and are not affected by terrestrial weathering.

A "~" as opposed to a "find" is a meteorite whose arrival on Earth is witnessed. Stones constitute 92% of the observed falls.

Updated ~ 2007: Critics of darwinian evolution often quote mind-boggling numbers like I do in the previous paragraph to show that natural origins (not supernatural) are simply so statistically IMprobable that one must conclude that a purely natural origin to life is impossible.

A "~" means the meteorite was witnessed by someone as it fell from the sky. A "find" means the meteorite was not witnessed and the meteorite was found after the fact. About 33% of the meteorites are witnessed falls. The following table is from a book by Vagn F. Buchwald.

The ~ constellation Andromeda is a Princess. She looks like a "V"! Andromeda is close to the north pole, so only a few people in the Southern Hemisphere can see it in the spring.

In the ~ of 1924, on a photographic plate of the Andromeda Nebula, Hubble discovered something even more remarkable: Cepheid variable stars. As was discovered by Henrietta Leavitt at Harvard, Cepheids varied in brightness with a period directly proportional to their intrinsic brightness.

In the ~ of 2005 the instrument was moved to its current location atop the Physics/Optics Building on the University of Alabama, Huntsville campus. This new location makes the instrument available for use by students.

In the ~ of 1831 Faraday attempted to determine just how an induced current was produced. His original experiment had involved a powerful electromagnet, created by the winding of the primary coil. He now tried to create a current by using a permanent magnet.

Meteors ~ into the Earth's atmosphere all the time... tons of them every year. But when the Earth passes through the debris left behind by a comet, then you get lots of meteors at once.... a shower.

"They all ~ within about a million years of each other," says Kaib. "Whether they are actually associated with this extinction event is not certain.

After the ~ of the Old Kingdom came a roughly 200-year stretch of time known as the First Intermediate Period, which is generally thought to include a relatively obscure set of pharaohs running from the end of the Sixth to the Tenth, and most of the Eleventh Dynasty.

Supernovae ~ into two different types whose evolutionary history is different. Type I supernovae result from mass transfer inside a binary system consisting of a white dwarf star and an evolving giant star.

Dew does not "~" from the sky. It condenses from the surrounding air onto any object that's colder than the air's dew point. The dew point, often mentioned in weather broadcasts, depends on both temperature and humidity.

Some galaxies ~ outside the commonly recognized sequences. Many of these are "train wrecks", transient forms produced by the interaction or merger of galaxies.

The satellites ~ into three fairly natural groups. First, there are the "small" moons"irregularly shaped chunks of ice, all less than 300 km across"that exhibit a bewildering variety of complex and fascinating motion.

If you were to ~ into a black hole the thing that would kill you would be the tidal force. The tidal force (so named because it accounts for the tides on the Earth) is due to a body receiving different amounts of gravitational force.

The two brighter stars of the exquisite constellation Delphinus (the Dolphin) ~ well outside the traditional systems of naming stars after their characters or constellation placements (however confused these have become).

This mission will be divided into 3 stages: round, ~ and return. With the development of Chinese spaceflight business, accuracy requirement of orbit determination for the spacecraft will be more and more high.

The most obvious possibility is that the first phase of vigorous star formation was essentially complete prior to z = 10 (which, coincidentally, is when the universe is approximately 1 galactic free-~ time old).

These layers don't ~ in because the high pressure of the gases inside of the star prevent that. The star is balanced - it doesn't cave in on itself or blow itself apart.
Conservation of Energy - Energy is given off but it is continually produced.

I have been observing since the ~ of 1982 and every observing session is recorded in my logbook. Each session describes where I was observing from, who was observing with me (if I had company), what I saw, and what each object looked like.

Meteorites that are discovered by accident are called "finds"; those discovered because someone has seen a meteorite ~ are called "falls" (well, sometimes even scientific nomenclature is simple and logical!).

(An analogous situation is watching rain ~ from a moving train - although a raindrop is falling straight to the ground, it will appear to ~ at a slant, and the slant increases as the train's speed increases.) The aberration of light is due to the fact that light travels at a finite speed (as ...

Most scopes found at the Nature/Science stores at your local mall also ~ under this category. These telescopes are little more than toys and will likely kill your budding enthusiasm. Buy from a retailer who specializes in serious amateur telescopes.

Around the world, farmers know that for most crops, you plant in the spring and harvest in the ~. But in some regions, there is not much differentiation between the seasons. Since different constellations are visible at different times of the year, you can use them to tell what month it is.

This happens when (1) we use a magnification that is so low that the speckles ~ below the spatial or temporal resolution of the fovea, or (2) we use an aperture so small that the speckles ~ below the telescope resolution.

Last ~ I added two windows for the southern US States. For the southwestern US these are good, but for the southeastern US, all weather numerical models have problems in forecasting deep convection from April to October.

Because of this difference between the lunar year and the seasonal year, the quarter moon one lunar year from now (2003) won't ~ on Veterans Day, but on Halloween. It's inevitable, however, that the first quarter moon and Veterans Day will realign once again.

These four giants neatly ~ into two pairs: the giant gaseous planets of Jupiter and Saturn, and the giant ice planets of Uranus and Neptune. This separation is largely a consequence of size.

1638 - Galileo Galilei demonstrates that unequal weights would ~ with the same finite speed in a vacuum, and that their time of descent is independent of their mass. Thus, freely falling bodies, heavy or light, have the same constant acceleration, due to the force of gravity.

There is a class of objects known as “radio stars' that emit radio waves although all radio stars do not ~ into one category.

Short Description: Students discover how the moon's gravitational pull causes the level of the ocean to rise and ~ twice a day along most coastlines through this kinesthetic activity. They also consider what the Earth's tides might have been like if there were no moon.

They are icy rocks originating from the very outer regions of the solar system, where the gravity of the massive planets can cause them to '~' into the inner solar system.

Because the physical properties of stars are interrelated, stars do not ~ randomly on such a diagram, but instead lie in well-defined regions according to their state of evolution.

These are some of the main arguments that the conspiracy theorists put forward and as you can see with the appliance of science and a bit of common sense they quickly ~ apart. Now lets turn the spotlight around 180 degrees and see how the conspiracy holds up when it is examined.
