The four main classes of molecules in biochemistry (often called biomolecules) are carbohydrates, lipids, proteins, and nucleic acids. Many biological molecules are polymers: in this terminology, monomers are relatively small micromolecules that are linked together to create large macromolecules known as polymers. When monomers are linked together to synthesize a biological polymer, they undergo a process called dehydration synthesis. Different macromolecules can assemble in larger complexes, often needed for biological activity.
If a let is called, the rally is stopped and replayed with no change to the score. Lets may occur because of some unexpected disturbance such as a shuttlecock landing on court (having been hit there by players playing in adjacent court) or in small halls the shuttle may touch an overhead rail which can be classed as a let.
If the receiver is not ready when the service is delivered, a let shall be called; yet, if the receiver attempts to return the shuttlecock, the receiver shall be judged to have been ready.
When defending against a smash, players have three basic options: lift, block, or drive. In singles, a block to the net is the most common reply. In doubles, a lift is the safest option but it usually allows the opponents to continue smashing; blocks and drives are counter-attacking strokes, but may be intercepted by the smasher's partner. Many players use a backhand hitting action for returning smashes on both the forehand and backhand sides, because backhands are more effective than forehands at covering smashes directed to the body. Hard shots directed towards the body are difficult to defend.
The service is restricted by the Laws and presents its own array of stroke choices. Unlike in tennis, the server's racquet must be pointing in a downward direction to deliver the serve so normally the shuttle must be hit upwards to pass over the net. The server can choose a low serve into the forecourt (like a push), or a lift to the back of the service court, or a flat drive serve. Lifted serves may be either high serves, where the shuttlecock is lifted so high that it falls almost vertically at the back of the court, or flick serves, where the shuttlecock is lifted to a lesser height but falls sooner.
The Swiss-born art historian Heinrich Wlfflin (18641945) started the rehabilitation of the word Baroque in his Renaissance und Barock (1888); Wlfflin identified the Baroque as "movement imported into mass", an art antithetic to Renaissance art. He did not make the distinctions between Mannerism and Baroque that modern writers do, and he ignored the later phase, the academic Baroque that lasted into the 18th century. Long despised, Baroque art and architecture became fashionable between the two World Wars, and has largely remained in critical favour. For example, the often extreme Sicilian Baroque architecture is today recognised largely due to the work of Sir Sacheverall Sitwell, whose Southern Baroque Art of 1924 was the first book to appreciate the style, followed by the more academic work of Anthony Blunt. In painting the gradual rise in popular esteem of Caravaggio has been the best barometer of modern taste.
In art history it has become common to recognise "Baroque" stylistic phases, characterised by energetic movement and display, in earlier art, so that Sir John Boardman describes the ancient sculpture Laocon and His Sons as "one of the finest examples of the Hellenistic baroque", and a later phase of Imperial Roman sculpture is also often called "Baroque". William Watson describes a late phase of Shang-dynasty Chinese ritual bronzes of the 11th century BC as "baroque".
The term "Baroque" may still be used, usually pejoratively, describing works of art, craft, or design that are thought to have excessive ornamentation or complexity of line.
