Contents • • • • Famous experimental errors [ ] • (1903) A reported faint visual effect that experimenters could still 'see' even when the supposed causative element in their apparatus had been secretly disconnected. • (1906) – claimed experimental disproof of special relativity Published in Annalen der Physik and said to be the first journal paper to cite Einstein's 1905 electrodynamics paper. Kaufmann's paper stated that his results were not compatible with special relativity. According to, it took a decade for the shortcomings of Kaufmann's test to be realised: during this time, critics of special relativity were able to claim that the theory was invalidated by the available experimental evidence. • (1924) – premature verification of the effect. A number of earlier experimenters claimed to have found the presence or lack of gravitational redshift, but Adams' result was supposed to have settled the issue.
Appendix E - SAWG Enclosure A - Measurement Error 8-8-06 Page 2 of 10 A. Dilution error Dilution errors are those errors associated with the sample preparation from. May 23, 2018. The hemacytometer has gone through a series of major developments over the past. Dell model pp04x drivers. Those sources of error will be outlined here, followed by a. An experiment to measure how sampling area and dilution factors affected variation in cell counts. Physics in Medicine and Biology 1996; 41(3): 523-37.
Unfortunately the measurement and the prediction were both in error such that it initially appeared to be valid. It is no longer considered credible and there has been much debate about whether the results were fraud or that his data may have been contaminated by stray light from. The first 'reliable' confirmations of the effect appeared in the 1960s.
• First reproducible (1955) Originally reported in Nature in 1955 and later. Diamond synthesis was later determined to be impossible with the apparatus. Subsequent analysis indicated that the first gemstone (used to secure further funding) was natural rather than synthetic. Artificial diamonds have since been produced. • Claimed (1970) In 1970 Joseph Weber, an electrical engineer turned physicist, and working with the University of Maryland, reported the detection of 311 excitations on his test equipment designed to measure gravitational waves. He utilized an consisting of two one ton aluminum bars, each a separate detector, in some configurations being hung within a vacuum chamber, or having one bar displaced to Argonne National Laboratory, near Chicago, about 1,000 kilometers away, all for further isolation.
He took extreme measures to isolate the equipment from seismic and other interferences. But Weber's criteria for data analysis turned out to be ill-defined and partly subjective.
By the end of the 1970s Weber's work was considered spurious as it could not be replicated by others. Still Weber is considered one of the fathers of gravitational wave detection and inspiration for other projects such as. • (1976) Data from in 1976 appeared to indicate a new particle at about 6 GeV which decayed into electron-positron pairs. Subsequent data and analysis indicated that the apparent peak resulted from random noise. The name is a pun on upsilon, the proposed name for the new particle and, the principal investigator.
