However, despite the insight of many of his observations, his own conclusions are open to suspicion because of his failure to employ at all times the correct research methods.

However neither of those observations became accepted by British economists at the time.

However, spectropolarimetric observations of SN 2009dc showed it had a polarization smaller than 0. 3, making the large asphericity theory unlikely.

However, at the current level of accuracy, these observations cannot distinguish between general relativity and other theories in which the equivalence principle is valid.

However, if rotation were found, interpretation of observations in a frame tied to the Universe would have to be corrected for the fictitious forces inherent in such rotation.

However, neither Stephens's nor Sassetti's observations led to further scholarly inquiry.

However, the result of the observations was not as conclusive or accurate as had been hoped.

However, the idea of inflation ( for which this problem served as a partial motivation ) was successful in solving this problem, creating models in which monopoles existed but were rare enough to be consistent with current observations.

However, a former assistant ( and later an astronomer in his own right ), Peder Horrebow, loyally described and wrote about Rømer's observations.

However the need for reproducibility requires that observations by different observers can be comparable.

However, after a series of clinical observations by Henry Head and experiments by Max von Frey, the psychologists migrated to specificity almost en masse, and by century's end, most textbooks on physiology and psychology were presenting pain specificity as fact.

However, unlike the backstaff, the sextant allows direct observations of stars.

However, present observations cannot exclude the possibilities that the universe has more dimensions and that its spacetime may have a multiply connected global topology, in analogy with the cylindrical or toroidal topologies of two-dimensional spaces.

However, a number of observations including the discovery of cosmic acceleration in 1998 have revived the cosmological constant, and the current standard model of cosmology includes this term.

However, soon after Einstein developed his static theory, observations by Edwin Hubble indicated that the universe appears to be expanding ; this was consistent with a cosmological solution to the original general-relativity equations that had been found by the mathematician Friedmann.

However, observations do not seem to support this picture: long-time lowest-mass X-ray detection, VB 8 ( M7e V ), has shown steady emission at levels of X-ray luminosity ( L < sub > X </ sub >) ≈ 10 < sup > 26 </ sup > erg · s < sup >− 1 </ sup > ( 10 < sup > 19 </ sup > W ) and flares up to an order of magnitude higher.

However, observations conducted around the time of Halley's Comet's appearance in 1986 suggest that the Eta Aquarid meteor shower might not originate from Halley's Comet, though it might be perturbed by the comet.

However, for those hallucinations caused by mental disease, a psychologist or psychiatrist should be alerted, and treatment will be based on the observations of those doctors.

However, this theory only explained experimental observations — it did not allow the microscopic origins of the superconducting properties to be identified.

However, precise long-term observations show that the constellations change shape, albeit very slowly, and that each star has an independent motion.

However, observations of Dione, which has an even darker trailing hemisphere and similar but more prominent bright streaks, show that the streaks are actually ice cliffs resulting from extensive fracturing of the moon's surface.

However, when Cassini made targeted observations of the putative ring plane from several angles, no evidence of ring material was found, suggesting that another explanation for the earlier observations is needed.

" However, earlier examples of international scientific cooperation exist, notably the 18th-century observations of the transits of Venus.

However, a conscious observer ( according to his reasoning ) must be in either one state or the other, hence conscious observations are different, hence consciousness is not material.

However, as much time as possible should be spent within the shelter to hold radiation exposure to a minimum.

However, another component of alpha radiation is the recoil of the parent nucleus, termed alpha recoil.

However, it remains difficult to find a solution to the coronal heating problem as these structures are being observed remotely, where many ambiguities are present ( i. e. radiation contributions along the LOS ).

However, in the far-field EM radiation which is described by the two source-free Maxwell curl operator equations, a more correct description is that a time-change in one type of field is proportional to a space-change in the other.

However, in 1900 the French scientist Paul Villard discovered a third neutrally charged and especially penetrating type of radiation from radium, and after he described it, Rutherford realized it must be yet a third type of radiation, which in 1903 Rutherford named gamma rays.

However, when the absorbed electromagnetic radiation is intense, it is possible for one electron to absorb two photons ; this two-photon absorption can lead to emission of radiation having a shorter wavelength than the absorbed radiation.

However, in this context it becomes inaccurate when the diffusion constant is low and the radiation becomes limited by the speed of light rather than by the resistance of the material the radiation is flowing through.

However, since the Earth reflects about 30 % of the incoming sunlight, the planet's effective temperature ( the temperature of a blackbody that would emit the same amount of radiation ) is about − 18 ° C, about 33 ° C below the actual surface temperature of about 14 ° C.

However there are limitations in measuring high radiation rates and in measuring the energy of incident radiation.

However, the G-M tube produces a pulse output which is the same magnitude for all detected radiation, so a Geiger counter with an end window tube cannot distinguish between alpha and beta particles.

However, those experiments could be either not verified in later experiments, could not be clearly attributed to the radiation effect, or could be attributed to an inappropriate design of the experiment etc.

However, this type of UV radiation is significantly less harmful to DNA, although it may still potentially cause indirect genetic damage in skin ( see ultraviolet for more about UV-A ).

However, when confronted with totally unexpected phenomena, such as the first evidence for invisible radiation, experimental scientists often use the same approach as historical scientists: construct a set of hypotheses about the causes and then look for a " smoking gun ".

However, it slowly decays, with the half-life of 32, 760 years, into < sup > 227 </ sup > Ac, which has a specific activity of 74 Ci / gram, emits both alpha and beta radiation, and has a much shorter half-life of 22 years.

However, if the electromagnetic radiation hitting the metal cap does not have a high enough frequency ( its frequency is below the threshold value for the cap ), then the leaf will never discharge, no matter how long one shines the low-frequency light at the cap.

However, the extreme resistance of Deinococcus radiodurans to radiation, cold, dehydration and vacuum shows that at least one known organism is capable of surviving the hazards of space without need for special protection.

However, the slowdown of the Earth's rotation is not occurring fast enough for the rotation to lengthen to a month before other effects make this irrelevant: About 2. 1 billion years from now, the continual increase of the Sun's radiation will cause the Earth's oceans to vaporize, removing the bulk of the tidal friction and acceleration.

However, the entire spectrum of ultraviolet radiation has some of the biological features of ionizing radiation, in doing far more damage to many molecules in biological systems than is accounted for by simple heating effects ( an example is sunburn ).

However, X-rays are composed of photons, and thus are not only waves of electromagnetic radiation but also exhibit particle-like properties.
