[ noun ] the act of making and recording a measurement
Used in print (Cornell H. Mayer, "Radio Emission of the Moon...)The results of present observations of the thermal radio_emission of the moon are consistent with the very low thermal conductivity of the surface layer which was derived from the variation in the infrared_emission during eclipses ( e.g. , Garstung , 1958 ) . Observations of the radio_emission of a planet which has an extensive atmosphere will probe the atmosphere to_a_greater_extent than those using shorter wave_lengths and should in some cases give otherwise unobtainable information about the characteristics of the solid surface . The low intensity of the radiation from Saturn has limited observations , but again the measured radiation seems to be consistent with a thermal origin . This was followed by a comprehensive series of observations of the 1.25 - cm emission of the moon over three lunar cycles by Piddington and Minnett ( 1949 ) . Piddington and Minnett explained their observations by pointing_out that rocklike materials which are likely to make_up the surface of the moon would be partially transparent to radio_waves , although opaque to infrared_radiation .

[ noun ] the act of observing; taking a patient look
Synonyms Used in print (Cornell H. Mayer, "Radio Emission of the Moon...)The 10.3 - cm observation of Sloanaker was made on May 20 , 1958 , using the 84 - foot reflector at the Maryland_Point_Observatory of the U.S._Naval_Research_Laboratory . (Jacob Robbins et al., "The thyroid-stimulating...)The importance of knowing in what chemical forms the hormone may exist is accentuated by the recent observation that there exists an abnormally long-acting TSH in blood drawn from many thyrotoxic patients ( Adams , 1958 ) . (E. Gellhorn, "Prolegomena to a theory of the emotions"...)An important observation of Pavlov served as a guide_post to achieve such a reversibility by physiological means .

[ noun ] the act of noticing or paying attention
Synonyms Examples "he escaped the notice of the police" Used in print (Norman Kent, "The Watercolor Art of Roy M. Mason"...)Long observation has taught Mason that most landscape can be reduced to three essential planes : a foreground in sharp focus - either a light area with dark accents or a dark one with lights ; a middle_distance often containing the major motif ; and a background , usually a silhouetted form foiled against the sky . |
