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.
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.
FALL - Meteorite seen to fall. Such meteorites are usually collected soon after falling and are not affected by terrestrial weathering.
Fall
A "fall" as opposed to a "find" is a meteorite whose arrival on Earth is witnessed. Stones constitute 92% of the observed falls.

Fall: A meteorite that was observed as it fell through Earth's atmosphere and was retrieved. Since most falls are collected soon after hitting the ground, these meteorites are not badly degraded or weathered.
fall: A meteorite seen to fall. (See find.)

A "fall" 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.
AGN fall into two major divisions: radio-loud and radio-quiet. Within each is a broad range of luminosity, ...
The fall-off in density is probably due to the fact that many stars are too faint to be cataloged at a distance more than 5 parsecs.
The fall 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.
The fall of meteoric matter into the sun must be a certain source of energy; if considerable, this external supply would retard the sun's contraction and so increase its estimated age, but to bring about a reconciliation with geological theory, ...
This fall, the brightest star-like object you can see in the eastern skies before dawn isn't a star at all - it's Venus, the second closest planet to the Sun.
they fall over the sparcely populated areas that make up the majority of the Earth (including the oceans).
they fall during the day and are masked by the brightness of the Sun.
they fall during the night when few people are awake to observe them.
FREE FALL
Free fall is a state that occurs while in orbit around a planet. In free fall, things appear to weightless.

In the fall 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 fall 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.
Meteors fall 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.
After the fall of Rome, European astronomy was largely dormant, but significant work was carried out by the Muslims and the Hindus. It was by way of Arabic translations that Greek astronomy reached medieval Europe.
"They all fall within about a million years of each other," says Kaib. "Whether they are actually associated with this extinction event is not certain.
After the fall 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, ...
Supernovae fall 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.
During the fall of 1995, the comet had a huge outburst in activity and shortly afterwards four separate nuclei were identified and labeled "A", "B", "C", and "D", with "C" being the largest and the presumed principal remnant of the original nucleus.
Moon rocks fall into two main categories, based on whether they underlie the lunar highlands (terrae) or the maria.
* It would fall to Morgan's scientific successors to dovetail Mendelian genetics to Darwinian evolutionary concepts. The pioneers in this effort were the Scots biochemist John Burdon Sanderson Haldane (1892:1964), the English geneticist Ronald A.

Some galaxies fall outside the commonly recognized sequences. Many of these are "train wrecks", transient forms produced by the interaction or merger of galaxies.
fall (NASA SP-7, 1965) Of a spacecraft or spatial body, to drop toward another spatial body under the influence of the latter's gravity.
The satellites fall 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 fall 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.
free fall 1. The fall or drop of a body, such as a rocket, not guided, not under thrust, and not retarded by a parachute or other braking device. 2.
COLLAPSE

Produced during the fall of the Soviet Union in the early 1990s, the film's plot may be regarded as a metaphor for those events and the effect they had on international relations at that time.
It shows that stars fall into several main groups including the main sequence, giants, supergiants and white dwarfs. Comparing stars on the diagram allows u to infer their properties and better understand their evolutionary path.
The two brighter stars of the exquisite constellation Delphinus (the Dolphin) fall well outside the traditional systems of naming stars after their characters or constellation placements (however confused these have become).
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-fall time old).
These layers don't fall 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.
I have been observing since the fall 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 fall are called "falls" (well, sometimes even scientific nomenclature is simple and logical!).
(An analogous situation is watching rain fall from a moving train - although a raindrop is falling straight to the ground, it will appear to fall at a slant, and the slant increases as the train's speed increases.) The aberration of light is due to ...
This has been determined on the basis of the time of day during which meteorites are observed to fall. It has been noted that about twice as many ordinary chondrites fall during the daylight afternoon hours as during daylight hours before noon.
What would happen if you were to fall into a black hole? As the you approach the black hole, your watch would begin to run slower than the watch of your colleagues on the spaceship. Also, your comrades notice that you begin to take on a reddish color.
Most scopes found at the Nature/Science stores at your local mall also fall under this category. These telescopes are little more than toys and will likely kill your budding enthusiasm.
Around the world, farmers know that for most crops, you plant in the spring and harvest in the fall. But in some regions, there is not much differentiation between the seasons.
This happens when (1) we use a magnification that is so low that the speckles fall below the spatial or temporal resolution of the fovea, or (2) we use an aperture so small that the speckles fall below the telescope resolution.
Last fall 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 fall on Veterans Day, but on Halloween.
Occasionally, a member of the Oort Cloud or Kuiper Belt is nudged from its orbit and begins to fall toward the Sun. As it gets close to the Sun, it gets warmer.
These four giants neatly fall 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.
Any orbiting body, including the space shuttle or the International Space Station is in constant free fall.
