The Serpentine

The Serpentine is a engineering topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand The Serpentine rather than just read about it. In short: The Serpentine (also known as the Serpentine River) is a 40-acre (16 ha) recreational lake in Hyde Park, London, England, created in 1730 at the behest of Queen Caroline. Although it is common to refer to the entire body of water as the Serpentine, the name refers in the strict sense only to the eastern half of the lake.

Key takeaways

  • The Serpentine belongs to engineering; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect The Serpentine to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of The Serpentine from memory before moving on to harder problems.

Reference excerpt

The Serpentine (also known as the Serpentine River) is a 40-acre (16 ha) recreational lake in Hyde Park, London, England, created in 1730 at the behest of Queen Caroline. Although it is common to refer to the entire body of water as the Serpentine, the name refers in the strict sense only to the eastern half of the lake. Serpentine Bridge, which marks the boundary between Hyde Park and Kensington Gardens, also marks the Serpentine's western boundary; the long and narrow western half of the lake is known as the Long Water. The Serpentine takes its name from its snakelike, curving shape, although it only has one bend. Originally fed by the River Westbourne and Tyburn Brook in the 1730s, the lake's water was then pumped from the Thames in the 1830s. The water is now pumped from three boreholes within Hyde Park, the most recent being installed in May 2012 as part of the 2011–2012 restoration of the lake. The Serpentine provided a focal point for The Great Exhibition of 1851, and more recently was a venue for the men's and women's triathlon and marathon swimming events in the London 2012 Olympics. Since 1864, the Serpentine Swimming Club has organised a 100-yard race every Christmas morning. In 1913, the Peter Pan Cup was inaugurated for this race by J. M. Barrie, the creator of the fictional character Peter Pan. There are many recreational facilities around the Serpentine, as well as boating on the lake itself. In 1860, the Serpentine was to be modified into a skating pond with formal edges. This scheme was not implemented. Among the landmarks near the lake is the Diana, Princess of Wales Memorial Fountain.

Geography of the lake

Originally the lake was fed by the River Westbourne entering at the Italian Garden at the north-western end of the Long Water. The Westbourne ceased to provide the water for the Serpentine in 1834, as it had become polluted so water was for some years pumped from the tidal Thames. The water is now supplied by three boreholes drilled into the Upper Chalk. The first borehole is at the Italian Gardens, the second at the Diana Memorial and the third, drilled in 2012 to a depth of 132 m (433 ft), is within 50 m (160 ft) of there. The Long Water runs south-east from this point to Serpentine Bridge, where the lake curves to the east, following the natural contours of the land. At the eastern end, water flows out via a sluice in the dam, forming a small ornamental waterfall at the Dell where a small garden exists landscaped in the 1870s by Lord Redesdale. The outflow has not historically maintained the waterfall, and re-circulation pumps were installed in the Dell, below the dam, to sustain this feature. The restoration work in 2012 restored the flows into the Serpentine and this waterfall is now restored as originally designed. Historically the river flowed mainly exposed due south from this point as the mutual limits of Westminster and Kensington, but since 1850 is culverted (runs underground) to reach the Thames near Chelsea Bridge. The lake has a maximum depth of 17 ft (5.2 m); it is often reported to be deeper, but bathymetric surveys by the Royal Park in 2010 revealed the design of the lake. There are two lakeside restaurants and various recreational facilities on the lake shore.

History

In 1730 Queen Caroline, wife of George II, ordered the damming of the River Westbourne in Hyde Park as part of a general redevelopment of Hyde Park and Kensington Gardens. Original monastic ponds may have existed in the location and these were modified as part of the 1730–1732 scheme to create a single lake. At that time, the Westbourne formed eleven natural ponds in the park. During the 1730s, the lake filled to its current size and shape. The redevelopment was carried out by Royal Gardener Charles Bridgeman, who dammed the Westbourne to create the artificial lake, and dug a large pond in the centre of Kensington Gardens (The Round Pond) to be a focal point for pathways in the park. At the time of construction, artificial lakes were typically long and straight garden canals, as at St James's Park, where the canal was excavated in the 1660s (later turned into a curving lake). The Serpentine was one of the earliest artificial lakes designed to appear natural, and was widely imitated in parks and gardens nationwide.

The lake achieved notoriety in December 1816 when Harriet Westbrook, the pregnant wife of the poet Percy Bysshe Shelley, was found drowned in the Serpentine having left a suicide note addressed to her father, sister and husband. Shelley married Mary Wollstonecraft Godwin less than two weeks later.

The lake formed a focal point of the 1814 celebrations which marked a century of Hanoverian rule and re-enacted the British victory at Trafalgar nine years previously, and of the 1851 Great Exhibition, with the Crystal Palace standing on its southern shore. Following the introduction of more stringent regulations to protect the environment in the park, the relocation of the Crystal Palace, and the construction of the nearby Albertopolis complex of museums and exhibitions, large-scale events ceased to take place on the banks of the Serpentine. However, it was the location for the 1977 Silver Jubilee Exhibition, and a venue for the 2012 Olympics. In the 1820s, the park was extensively redesigned by Decimus Burton. At the same time, John Rennie the Younger designed and oversaw the Serpentine Bridge as part of newly built West Carriage Drive bounding Hyde Park against Kensington Gardens, dividing the lake into the Serpentine (east) and the Long Water (west).

Worked examples

Example 1 — a first encounter with The Serpentine

Start with the simplest possible case. Write down what The Serpentine claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In engineering, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to The Serpentine before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about The Serpentine ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of The Serpentine

In research
The Serpentine appears in engineering research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses The Serpentine in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
The Serpentine is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1730 establishments in England, Buildings and structures completed in 1730, Caroline of Ansbach, so understanding it makes those chapters shorter.
In everyday life
Look for The Serpentine outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
