Many Christian Scientists thought the book violated the church's by-laws, and the editors of the church's religious periodicals and several other church employees resigned in protest.

Christian Scientists see themselves as practicing a well-defined process with a proven track record by means of the spiritualization of thought through prayer aimed at shedding the false beliefs of the mortal mind that manifest themselves as physical ailments.

Scientists traditionally thought that the variation in the size of raindrops was due to collisions on the way down to the ground.

* Scientists Create Butterfly Hybrid-Creation of new species through hybridization was thought to be common only in plants, and rare in animals.

Scientists tend to use thought experiments in the form of imaginary, " proxy " experiments which they conduct prior to a real, " physical " experiment ( Ernst Mach always argued that these gedankenexperiments were " a necessary precondition for physical experiment ").

Scientists also use thought experiments when particular physical experiments are impossible to conduct ( Carl Gustav Hempel labeled these sorts of experiment " theoretical experiments-in-imagination "), such as Einstein's thought experiment of chasing a light beam, leading to Special Relativity.

He believed that scientists have an individual moral responsibility, and just as the Hippocratic Oath provides a code of conduct for physicians, he thought that scientists should have their own code of moral conduct, a Hippocratic Oath for Scientists.

Scientists have long thought that smelling one's own breath odor is often difficult due to acclimatization, although many people with bad breath are able to detect it in others.

Scientists originally thought that the heavy vegetation of tropical rain forests would provide rich nutrients, but as rainfall passes through the litter on the forest floor the rain is acidified and leaches minerals from the above soil layers.

Scientists hypothesize that these organisms survived the collapse of plant-based food chains because they fed on detritus ( non-living organic material ).< ref name =" SheehanHansen ">

Scientists expect to find a vast range of organic compounds in some of the planets, moons and comets of the outer Solar System, and the range of possible uses is even wider.

Scientists who took soil samples before draining did not take into account that the organic composition of peat and muck in the Everglades make it prone to soil subsidence when it becomes dry.

Scientists of the Manhattan Project recruited William T. Miller, a professor of organic chemistry at Cornell University, to synthesize and develop such materials, because of his expertise in organofluorine chemistry.

Scientists like Kekulé and Perkin cracked the secrets of organic chemistry to reveal how gas is made and its composition.

Scientists have found that maple syrup's natural phenols – potentially beneficial antioxidant compounds – inhibit two carbohydrate-hydrolyzing enzymes that are relevant to type 2 diabetes.

Scientists were unable to prepare compounds of argon until the end of the 20th century, but these attempts helped to develop new theories of atomic structure.

Scientists have been increasingly able to attribute the observed ozone depletion to the increase of man-made ( anthropogenic ) halogen compounds from CFCs by the use of complex chemistry transport models and their validation against observational data ( e. g. SLIMCAT, CLaMS — Chemical Lagrangian Model of the Stratosphere ).

Scientists around this time began discovering many biochemical compounds that play a significant role in biological processes and pepsin was one of them.

Scientists use this instrument to measure the amount of compounds in a sample.

Scientists and clinicians test their metal-back to the future with platinum compounds.

Scientists say that the world and everything in it are based on mathematics.

Scientists who agitate hardest for technical recognition are often the most reluctant to accept it.

Scientists figure humans may be born with a fear of spiders and snakes, which are healthy phobias that up the odds of survival in the wild.

Scientists engaged in chemical research are known as chemists.

Christian Scientists are trinitarian, but in an unorthodox way.

While reliance on prayer is central to Christian Science, Christian Scientists are not officially required to refuse medicine.

Christian Scientists are instructed to follow Jesus ' example and heal as well, as the words in the registered trademark of the Cross and Crown indicate.

Scholars who are not Christian Scientists rely on it, but church members strongly disfavor it.

Scientists currently think that cnidarians, ctenophores and bilaterians are more closely related to calcareous sponges than these are to other sponges, and that anthozoans are the evolutionary " aunts " or " sisters " of other cnidarians, and the most closely related to bilaterians.

The epitaph on his tombstone in Göttingen are the famous lines he spoke at the conclusion of his retirement address to the Society of German Scientists and Physicians in the fall of 1930.

Scientists with the Ventana Wildlife Society and others are intensifying studies and remediations of the condors ' problems.

Internationally-recognised musicians such as metal acts Striborg and Psycroptic, indie-electro bands The Paradise Motel and The Scientists of Modern Music, singer / songwriters Sacha Lucashenko ( of The Morning After Girls ), Michael Noga ( of The Drones ), and Monique Brumby, two-thirds of indie rock band Love of Diagrams, post punk band Sea Scouts, blues guitarist Phil Manning ( of blues-rock band Chain ), power-pop group The Innocents are all successful expatriates.

Scientists at the GSI are planning to search for K-isomers in < sup > 270 </ sup > Hs using the reaction < sup > 226 </ sup > Ra (< sup > 48 </ sup > Ca, 4n ) in 2010.

Scientists of Russian Academy of Sciences are searching for methods of reducing the risk of radiation-induced cancer in preparation for the mission to Mars.

Scientists and engineers are able to use liquid crystals in a variety of applications because external perturbation can cause significant changes in the macroscopic properties of the liquid crystal system.

Scientists are learning about the phenomenon.

Scientists are researching the use of algae to produce liquid fuels, and bacteria to convert various forms of agricultural and urban waste into usable fuels.

Scientists are also considering using microbes for living fuel cells, and as a solution for pollution.

Scientists critical of parapsychology state that its extraordinary claims demand extraordinary evidence if they are to be taken seriously.

Scientists are also distinct from engineers, those who develop devices that serve practical purposes.

Scientists have argued that the evidences of sympatric speciation are in fact examples of micro-allopatric, or heteropatric speciation.
