Usually, a hybrid search engine will favour one type of listing over another. For example, MSN Search is more likely to present human-powered listings from LookSmart.

Following Einstein's realist position, it would be natural to assume that the particle has to pass through either slit. We can still do the experiment by putting a photographic plate at the observation screen and sending many photons in, one at a time. After a long enough time, we look at the photographic plate. to represent the eye -piece of a telescope. The stage, condensers, and reflectors, arc all removed, and in front of the eye -piece a tube carrying a telescope objective is mounted. It will be seen that the appara-tus is a combination of a telescope and a microscope. In the everyday microscope objects are held within a small fraction of.

The zenith tube or telescope consists of a small refractor which is limited in movement so thatonly the zenith field can be observed. In its basic form, the measurements are made using a micrometereyepiece but there are several more modern versions using photographic and electronic recordingtechniques which provide improved accuracy.

In the hands of the Greeks and of the later Egyptians both astrology and astronomy were carried far beyond the limits attained by the Babylonians, and it is indeed a matter of surprise to observe the harmonious combination of the two fields - a harmony that seems to grow more complete with each age, and that is not broken until we reach the threshold of modern science in the 16th century.

By measuring these angular distances of the star from the zenith, the astronomer finds the angles at the center of the earth between the stations 1, 2, 3, etc., at which his observations are made. If the meridian were a perfect circle the change of zenith distance of the star, as one traveled along a meridian from the equator to the pole, would.
