In October 2010, John Graham-Cumming started a campaign to raise funds by " public subscription " to enable serious historical and academic study of Babbage's plans, with a view to then build and test a fully working virtual design which will then in turn enable construction of the physical Analytical Engine.

Whorf argued that paying attention to how other physical phenomena are described in the study of linguistics could make valuable contributions to science by pointing out the ways in which certain assumptions about reality are implicit in the structure of language itself, and how language guides the attention of speakers towards certain phenomena in the world which risk becoming overemphasized while leaving other phenomena at risk of being overlooked.

The study of condensed matter physics involves measuring various material properties via experimental probes along with using techniques of theoretical physics to develop mathematical models that help in understanding physical behavior.

Around the 1960s, the study of physical properties of liquids were added to this list, and it came to be known as condensed matter physics.

* Physical chemistry is the study of the physical fundamental basis of chemical systems and processes.

A Danish study in 2000 found that even after adjustment for other risk factors, including leisure time physical activity, those who did not cycle to work experienced a 39 % higher mortality rate than those who did.

Chemical thermodynamics is the study of the interrelation of heat and work with chemical reactions or with physical changes of state within the confines of the laws of thermodynamics.

* Physical chemistry – study of the physical and fundamental basis of chemical systems and processes.

** Calorimetry – The study of heat changes in physical and chemical processes.

Critics of Dianetics are skeptical of this study, both because of the bias of the source and because the researchers appear to ascribe all physical benefits to Dianetics without considering possible outside factors ; in other words, the report lacks any scientific controls.

" Distance education courses that require a physical on-site presence for any reason ( including taking examinations ) have been referred to as hybrid or blended courses of study.

The study of human evolution involves many scientific disciplines, including physical anthropology, primatology, archaeology, linguistics, embryology and genetics.

Based on archaeological and paleontological evidence, it has been possible to infer, to some extent, the ancient dietary practices of various Homo species and to study the role of diet in physical and behavioral evolution within Homo.

English scholar Russell Martineau, who had studied under Bopp, gave the following tribute: “ Bopp must, more or less, directly or indirectly, be the teacher of all who at the present day study, not this language or that language, but language itself — study it either as a universal function of man, subjected, like his other mental or physical functions, to law and order, or else as an historical development, worked out by a never ceasing course of education from one form into another .”

For this reason, the study of the Earth's gravity field is called physical geodesy by some.

Historical Geography is the study of the human, physical, fictional, theoretical, and " real " geographies of the past.

For example, the identity of proteins of the immune system ( e. g. antibodies ), and the mechanism by which they recognize and bind to foreign antigens would remain very obscure if not for the extensive use of in vitro work to isolate the proteins, identify the cells and genes that produce them, study the physical properties of their interaction with antigens, and identify how those interactions lead to cellular signals that activate other components of the immune system.

Population-based studies ( e. g. Michael, et al., 2000 ) using the SF-36 have found significant decrease in QoL dimensions, including role / physical, bodily pain, vitality and social function, results that were supported by Rothrock's ( et al., 2002 ) cross-sectional study of IC patients showing decreased physical functioning, decreased ability to function in one's normal role, decreased vitality, and depression.

In 1992, a study by Deirdre Barrett examined whether lucid dreams contained four " corollaries " of lucidity: knowing that one dreams, that objects will disappear after waking, that physical laws need not apply, and having clear memory of the waking world, and found less than a quarter of lucidity accounts exhibited all four.

Apparently, however, Miller has relied heavily on the anatomy in dogs and cats, and he has been criticized for using pathologic human material in his normal study ( Loosli, '38 ).

This second conclusion, independently arrived at by independent study of material from two pairs of language families as different and remote from one another as these four are, cannot be ignored.

Cultural anthropology also covers economic and political organization, law and conflict resolution, patterns of consumption and exchange, material culture, technology, infrastructure, gender relations, ethnicity, childrearing and socialization, religion, myth, symbols, values, etiquette, worldview, sports, music, nutrition, recreation, games, food, festivals, and language ( which is also the object of study in linguistic anthropology ).

Archaeology is the study of the human past through its material remains.

Geography, material culture, and what later Annalistes called mentalités, or the psychology of the epoch, are also characteristic areas of study.

* Molecular biology is the study of molecular underpinnings of the process of replication, transcription and translation of the genetic material.

Quantum oscillations is another experimental technique where high magnetic fields are used to study material properties such as the geometry of the fermi surface.

Key criteria are the composition of the clay and the temper used in the manufacture of the article under study: temper is a material added to the clay during the initial production stage, and it is used to aid the subsequent drying process.

Mail armour provided an effective defence against slashing blows by an edged weapon and penetration by thrusting and piercing weapons ; in fact a study conducted at the Royal Armouries at Leeds concluded that " it is almost impossible to penetrate using any conventional medieval weapon " Generally speaking, mail's resistance to weapons is determined by four factors: linkage type ( riveted, butted, or welded ), material used ( iron versus bronze or steel ), weave density ( a tighter weave needs a thinner weapon to surpass ), and ring thickness ( generally ranging from 18 to 14 gauge in most examples ).

Adolph, Cahill and Schul completed a study showing that emotional arousal facilitates the encoding of material into long term declarative memory.

Food webs are a type of concept map or a heuristic device that is used to illustrate and study pathways of energy and material flows.

Hutchinson's students, brothers Howard T. Odum and Eugene P. Odum, further developed a " systems approach " to the study of ecosystems, allowing them to study the flow of energy and material through ecological systems.

For example, it explains experts ' ability to recall large amounts of material displayed for only brief study intervals, provided that the material comes from their domain of expertise.

An empirical study of esotericism needs “ emic material and etic interpretation ”.
