Most coastal areas, with some exceptions, experience two high tides and two low tides every day.  Almost everyone is familiar with the concept of a 24-hour solar day, which is the time that it takes for a specific site on the Earth to rotate from an exact point under the sun to the same point under the sun.  Similarly, a lunar day (also known as a "tidal day") is the time it takes for a specific site on the Earth to rotate from an exact point under the moon to the same point under the moon.  Unlike a solar day, however, a lunar day is 24 hours and 50 minutes.  The lunar day is 50 minutes longer than a solar day because the moon revolves around the Earth in the same direction that the Earth rotates around its axis.  So, it takes the Earth an extra 50 minutes to “catch up” to the moon.  Because the Earth rotates through two tidal “bulges” every lunar day, coastal areas experience two high and two low tides every 24 hours and 50 minutes.  High tides occur 12 hours and 25 minutes apart.  It takes six hours and 12.5 minutes for the water at the shore to go from high to low, or from low to high.  https://oceanservice.noaa.gov/education/tutorial_tides/tides05_lunarday.html   

Tides are long-period waves that roll around the planet as the ocean is "pulled" back and forth by the gravitational pull of the moon and the sun as these bodies interact with the Earth in their monthly and yearly orbits.  During full or new moons—which occur when the Earth, sun, and moon are nearly in alignment—average tidal ranges are slightly larger.  This occurs twice each month.  The moon appears new (dark) when it is directly between the Earth and the sun.  The moon appears full when the Earth is between the moon and the sun.  In both cases, the gravitational pull of the sun is "added" to the gravitational pull of the moon on Earth, causing the oceans to bulge a bit more than usual.  This means that high tides are a little higher and low tides are a little lower than average.  These are called spring tides, a common historical term that has nothing to do with the season of spring.  Rather, the term is derived from the concept of the tide "springing forth."  Spring tides occur twice each lunar month all year long, without regard to the season.  Seven days after a spring tide, the sun and moon are at right angles to each other.  When this happens, the bulge of the ocean caused by the sun partially cancels out the bulge of the ocean caused by the moon.  This produces moderate tides known as neap tides, meaning that high tides are a little lower and low tides are a little higher than average.  Neap tides occur during the first and third quarter moon, when the moon appears "half full."  https://oceanservice.noaa.gov/facts/springtide.html   

Frank Lloyd Wright (1867–1959) was an American architect, designer, writer, and educator.  He designed more than 1,000 structures over a creative period of 70 years.  Wright believed in designing in harmony with humanity and the environment, a philosophy he called organic architecture.  This philosophy was exemplified in Fallingwater (1935), which has been called "the best all-time work of American architecture".  Wright played a key role in the architectural movements of the twentieth century, influencing architects worldwide through his works and hundreds of apprentices in his Taliesin Fellowship.  Wright was the pioneer of what came to be called the Prairie School movement of architecture and also developed the concept of the Usonian home in Broadacre City, his vision for urban planning in the United States.  He also designed original and innovative offices, churches, schools, skyscrapers, hotels, museums, and other commercial projects.  Wright-designed interior elements (including leaded glass windows, floors, furniture and even tableware) were integrated into these structures.  He wrote several books and numerous articles and was a popular lecturer in the United States and in Europe.  Wright was recognized in 1991 by the American Institute of Architects as "the greatest American architect of all time".  In 2019, a selection of his work became a listed World Heritage Site as The 20th-Century Architecture of Frank Lloyd Wright.  Raised in rural Wisconsin, Wright studied civil engineering at the University of Wisconsin and then apprenticed in Chicago, first with Joseph Lyman Silsbee (1887) and then with Louis Sullivan (1888).  He opened his own successful Chicago practice in 1893 and established a studio in his Oak Park, Illinois home in 1898.  https://en.wikipedia.org/wiki/Frank_Lloyd_Wright

shard is a broken piece of china, glass, ceramic, etc., with edges that are sharp.  Usually, shards are the result of shattering something such as a dish or glass.  The word shard is derived from the Old English word sceard, meaning gap or incision.   A sherd is a broken piece of pottery with edges that are sharp, usually referring to one that is found in an archaeological site.  In essence, the words shard and sherd are interchangeable, though the term sherd is favored by archaeologists.  Sherd is an abbreviation of the word potsherd, which has been in use since the 1300s.  https://grammarist.com/usage/shard-or-sherd/ 

'Mull Hill (Manx: Cronk Meayll also called Meayll Hill or The Mull) is a small hill in the exclave of Rushen Parish at the southern end of the Isle of Man, just outside the village of Cregneash.  It is the site of a chambered cairn called Mull Circle or Meayll Circle.  Near the summit of the hill also lie the remains of a World War II Chain Home Low RDF station.  Mull Hill Stone Circle is a unique archaeological monument.  It consists of twelve burial chambers placed in a ring, with six entrance passages each leading into a pair of chambers.  Sherds of ornate pottery, charred bones, flint tools and white quartz pebbles have been found in the burial chambers. This archaeological monument was built around 3500 BC; it is a site of legends with diverse stories about haunting.  The word Meayll means "bald" in Manx Gaelic.  See graphics at https://en.wikipedia.org/wiki/Mull_Hill
