Wilfrid Noel Bond
Wilfrid Noel Bond (27 December 1897 – 25 August 1937) was an English physicist and engineer known for his work in fluid mechanics. He received his Doctor of Science from the University of London, and was a lecturer at the University of Reading The University of Reading is a public university in Reading, Berkshire, England. It was founded in 1892 as University College, Reading, a University of Oxford extension college. The institution received the power to grant its own degrees in 192 ... from 1921 until his death. The Bond number, used in fluid mechanics to characterize the shape of bubbles and drops, is named after him.

St Albans, Hertfordshire
St Albans () is a cathedral city in Hertfordshire, England, east of Hemel Hempstead and west of Hatfield, north-west of London, south-west of Welwyn Garden City and south-east of Luton. St Albans was the first major town on the old Roman road of Watling Street for travellers heading north and became the city of Verulamium. It is within the London commuter belt and the Greater London Built-up Area. Name St Albans takes its name from the first British saint, Alban. The most elaborate version of his story, Bede's ''Ecclesiastical History of the English People'', relates that he lived in Verulamium, sometime during the 3rd or 4th century, when Christians were suffering persecution. Alban met a Christian priest fleeing from his persecutors and sheltered him in his house, where he became so impressed with the priest's piety that he converted to Christianity. When the authorities searched Alban's house, he put on the priest's cloak and presented himself in place of his guest. Cons ...

Minehead, Somerset
Minehead is a coastal town and civil parish in Somerset, England. It lies on the south bank of the Bristol Channel, north-west of the county town of Taunton, from the boundary with the county of Devon and in proximity of the Exmoor National Park. The parish of Minehead has a population of approximately 11,981, making it the most populous town in the western part of the Somerset West and Taunton local government district, which in turn, is the worst area in the country for social mobility. This figure includes Alcombe and Woodcombe, suburban villages which have been subsumed into Minehead. There is evidence of human occupation in the area since the Bronze and Iron Ages. Before the Norman conquest, it was held by Ælfgar, Earl of Mercia and after it by William de Moyon and his descendants, who administered the area from Dunster Castle, which was later sold to Sir George Luttrell and his family. There was a small port at Minehead by 1380, which grew into a major trading ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fluid Mechanics
Fluid mechanics is the branch of physics concerned with the mechanics of fluids (liquids, gases, and plasmas) and the forces on them. It has applications in a wide range of disciplines, including mechanical, aerospace, civil, chemical and biomedical engineering, geophysics, oceanography, meteorology, astrophysics, and biology. It can be divided into fluid statics, the study of fluids at rest; and fluid dynamics, the study of the effect of forces on fluid motion. It is a branch of continuum mechanics, a subject which models matter without using the information that it is made out of atoms; that is, it models matter from a ''macroscopic'' viewpoint rather than from ''microscopic''. Fluid mechanics, especially fluid dynamics, is an active field of research, typically mathematically complex. Many problems are partly or wholly unsolved and are best addressed by numerical methods, typically using computers. A modern discipline, called computational fluid dynamics (CFD), i ...

University Of London
The University of London (UoL; abbreviated as Lond or more rarely Londin in post-nominals) is a federal public research university located in London, England, United Kingdom. The university was established by royal charter in 1836 as a degree-awarding examination board for students holding certificates from University College London and King's College London and "other such other Institutions, corporate or unincorporated, as shall be established for the purpose of Education, whether within the Metropolis or elsewhere within our United Kingdom". This fact allows it to be one of three institutions to claim the title of the third-oldest university in England, and moved to a federal structure in 1900. It is now incorporated by its fourth (1863) royal charter and governed by the University of London Act 2018. It was the first university in the United Kingdom to introduce examinations for women in 1869 and, a decade later, the first to admit women to degrees. In 1913, it appoi ...

University Of Reading
The University of Reading is a public university in Reading, Berkshire, England. It was founded in 1892 as University College, Reading, a University of Oxford extension college. The institution received the power to grant its own degrees in 1926 by royal charter from King George V and was the only university to receive such a charter between the two world wars. The university is usually categorised as a red brick university, reflecting its original foundation in the 19th century. Reading has four major campuses. In the United Kingdom, the campuses on London Road Campus, London Road and Whiteknights Park, Whiteknights are based in the town of Reading itself, and Greenlands, Buckinghamshire, Greenlands is based on the banks of the River Thames in Buckinghamshire. It also has a campus in Iskandar Puteri, Malaysia. The university has been arranged into 16 academic schools since 2016. The annual income of the institution for 2016–17 was £275.3 million of which £35.4 mil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Liquid Bubble
A bubble is a globule of one substance in another, usually gas in a liquid. Due to the Marangoni effect, bubbles may remain intact when they reach the surface of the immersive substance. Common examples Bubbles are seen in many places in everyday life, for example: * As spontaneous nucleation of supersaturated carbon dioxide in soft drinks * As water vapor in boiling water * As air mixed into agitated water, such as below a waterfall * As sea foam * As a soap bubble * As given off in chemical reactions, e.g., baking soda + vinegar * As a gas trapped in glass during its manufacture * As the indicator in a spirit level Physics and chemistry Bubbles form and coalesce into globular shapes because those shapes are at a lower energy state. For the physics and chemistry behind it, see nucleation. Appearance Bubbles are visible because they have a different refractive index (RI) than the surrounding substance. For example, the RI of air is approximately 1.0003 and the RI of w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Drop (liquid)
A drop or droplet is a small column of liquid, bounded completely or almost completely by free surfaces. A drop may form when liquid accumulates at the lower end of a tube or other surface boundary, producing a hanging drop called a pendant drop. Drops may also be formed by the condensation of a vapor or by atomizer nozzle, atomization of a larger mass of solid. Water vapor will condense into droplets depending on the temperature. The temperature at which droplets form is called the dew point. Surface tension Liquid forms drops because it exhibits surface tension. A simple way to form a drop is to allow liquid to flow slowly from the lower end of a vertical tube of small diameter. The surface tension of the liquid causes the liquid to hang from the tube, forming a pendant. When the drop exceeds a certain size it is no longer stable and detaches itself. The falling liquid is also a drop held together by surface tension. Viscosity and pitch drop experiments Some substa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Alumni Of The University Of London
Alumni (singular: alumnus (masculine) or alumna (feminine)) are former students of a school, college, or university who have either attended or graduated in some fashion from the institution. The feminine plural alumnae is sometimes used for groups of women. The word is Latin and means "one who is being (or has been) nourished". The term is not synonymous with "graduate"; one can be an alumnus without graduating (Burt Reynolds, alumnus but not graduate of Florida State, is an example). The term is sometimes used to refer to a former employee or member of an organization, contributor, or inmate. Etymology The Latin noun ''alumnus'' means "foster son" or "pupil". It is derived from PIE ''*h₂el-'' (grow, nourish), and it is a variant of the Latin verb ''alere'' "to nourish".Merriam-Webster: alumnus .. Separate, but from t ...
