While under the jurisdiction of the Franciscan friars during the 17th century, it was established as a town on June 1, 1670 under the name San Pedro Macati out of Santa Ana de Sapa. The nearby Nuestra Señora de Gracia Church , changed into
300-677: A day were similar, but at springs the tides rose 7 feet (2.1 m) in the morning but 9 feet (2.7 m) in the evening. Pierre-Simon Laplace formulated a system of partial differential equations relating the ocean's horizontal flow to its surface height, the first major dynamic theory for water tides. The Laplace tidal equations are still in use today. William Thomson, 1st Baron Kelvin , rewrote Laplace's equations in terms of vorticity which allowed for solutions describing tidally driven coastally trapped waves, known as Kelvin waves . Others including Kelvin and Henri Poincaré further developed Laplace's theory. Based on these developments and
400-445: A day—is a third regular category. Tides vary on timescales ranging from hours to years due to a number of factors, which determine the lunitidal interval . To make accurate records, tide gauges at fixed stations measure water level over time. Gauges ignore variations caused by waves with periods shorter than minutes. These data are compared to the reference (or datum) level usually called mean sea level . While tides are usually

The daytime population of the city is estimated to be more than three million during a typical working day because of the large number of people who go to the city to work, shop, and do business. The name of Makati originates from the Tagalog word kati , meaning "[of the] low tide " or "[of the] ebb tide ", attributing to
1100-516: A smooth sphere covered by a sufficiently deep ocean under the tidal force of a single deforming body is a prolate spheroid (essentially a three-dimensional oval) with major axis directed toward the deforming body. Maclaurin was the first to write about the Earth's rotational effects on motion. Euler realized that the tidal force's horizontal component (more than the vertical) drives the tide. In 1744 Jean le Rond d'Alembert studied tidal equations for

Similar machines were used until the 1960s. The first known sea-level record of an entire spring–neap cycle was made in 1831 on the Navy Dock in the Thames Estuary . Many large ports had automatic tide gauge stations by 1850. John Lubbock was one of
1400-455: Is a useful concept. Tidal stage is also measured in degrees, with 360° per tidal cycle. Lines of constant tidal phase are called cotidal lines , which are analogous to contour lines of constant altitude on topographical maps , and when plotted form a cotidal map or cotidal chart . High water is reached simultaneously along the cotidal lines extending from the coast out into the ocean, and cotidal lines (and hence tidal phases) advance along

The city's only professional sports team is the Makati OKBet Kings , which joined the Maharlika Pilipinas Basketball League in its second season . Low tide Tides are the rise and fall of sea levels caused by the combined effects of the gravitational forces exerted by the Moon (and to
1700-422: Is at once cotidal with high and low waters, which is satisfied by zero tidal motion. (The rare exception occurs when the tide encircles an island, as it does around New Zealand, Iceland and Madagascar .) Tidal motion generally lessens moving away from continental coasts, so that crossing the cotidal lines are contours of constant amplitude (half the distance between high and low water) which decrease to zero at

Along the south-eastern border of Makati beyond Forbes Park are the Manila Golf Club and the Manila Polo Club . The Manila Golf Club features an 18-hole golf course. The Manila Polo Club counts among its polo enthusiasts some of the country's wealthiest people. The Makati Sports Club in Salcedo Village is another popular place for sports. The Makati Coliseum
2000-497: Is never time for the fluid to "catch up" to the state it would eventually reach if the tidal force were constant—the changing tidal force nonetheless causes rhythmic changes in sea surface height. When there are two high tides each day with different heights (and two low tides also of different heights), the pattern is called a mixed semi-diurnal tide . The changing distance separating the Moon and Earth also affects tide heights. When
2100-408: Is not necessarily when the Moon is nearest to zenith or nadir , but the period of the forcing still determines the time between high tides. Because the gravitational field created by the Moon weakens with distance from the Moon, it exerts a slightly stronger than average force on the side of the Earth facing the Moon, and a slightly weaker force on the opposite side. The Moon thus tends to "stretch"

Makati was the setting of what is believed to be the single biggest case of involuntary disappearance during martial law – the case of the " Southern Tagalog 10 " – ten activists from
2500-402: Is shorter than average, and stronger tidal currents than average. Neaps result in less extreme tidal conditions. There is about a seven-day interval between springs and neaps. Tidal constituents are the net result of multiple influences impacting tidal changes over certain periods of time. Primary constituents include the Earth's rotation, the position of the Moon and Sun relative to the Earth,
2600-419: Is the time required for the Earth to rotate once relative to the Moon. Simple tide clocks track this constituent. The lunar day is longer than the Earth day because the Moon orbits in the same direction the Earth spins. This is analogous to the minute hand on a watch crossing the hour hand at 12:00 and then again at about 1: 05 + 1 ⁄ 2 (not at 1:00). The Moon orbits the Earth in the same direction as

The count was later reduced to 292,743 in 2023 based on the same census when the Embo barangays were transferred to Taguig as a result of the cities' territorial dispute ruling. Makati currently ranks 14th in population size within Metro Manila . A majority of Makati residents identified their religious affiliation as Roman Catholic . Other groups having large number of members in
3900-426: The Earth rotates on its axis, so it takes slightly more than a day—about 24 hours and 50 minutes—for the Moon to return to the same location in the sky. During this time, it has passed overhead ( culmination ) once and underfoot once (at an hour angle of 00:00 and 12:00 respectively), so in many places the period of strongest tidal forcing is the above-mentioned, about 12 hours and 25 minutes. The moment of highest tide

The solid Earth deforms a bit, but ocean water, being fluid, is free to move much more in response to the tidal force, particularly horizontally (see equilibrium tide ). As the Earth rotates, the magnitude and direction of the tidal force at any particular point on the Earth's surface change constantly; although the ocean never reaches equilibrium—there

The beginning months of the 1970s marked a period of turmoil and change in the Philippines, particularly for the areas near the capital. A sudden glut of debt driven public works projects in
4300-427: The Moon and its phases. Bede starts by noting that the tides rise and fall 4/5 of an hour later each day, just as the Moon rises and sets 4/5 of an hour later. He goes on to emphasise that in two lunar months (59 days) the Moon circles the Earth 57 times and there are 114 tides. Bede then observes that the height of tides varies over the month. Increasing tides are called malinae and decreasing tides ledones and that
4400-626: The Moon is at first quarter or third quarter, the Sun and Moon are separated by 90° when viewed from the Earth (in quadrature ), and the solar tidal force partially cancels the Moon's tidal force. At these points in the lunar cycle, the tide's range is at its minimum; this is called the neap tide , or neaps . "Neap" is an Anglo-Saxon word meaning "without the power", as in forðganges nip (forth-going without-the-power). Neap tides are sometimes referred to as quadrature tides . Spring tides result in high waters that are higher than average, low waters that are lower than average, " slack water " time that
4500-459: The Moon is closest, at perigee , the range increases, and when it is at apogee , the range shrinks. Six or eight times a year perigee coincides with either a new or full moon causing perigean spring tides with the largest tidal range . The difference between the height of a tide at perigean spring tide and the spring tide when the moon is at apogee depends on location but can be large as a foot higher. These include solar gravitational effects,
4600-462: The Moon on the particle, and the gravitational force that would be exerted on the particle if it were located at the Earth's center of mass. Whereas the gravitational force subjected by a celestial body on Earth varies inversely as the square of its distance to the Earth, the maximal tidal force varies inversely as, approximately, the cube of this distance. If the tidal force caused by each body were instead equal to its full gravitational force (which
4700-457: The Moon's altitude (elevation) above the Earth's Equator, and bathymetry . Variations with periods of less than half a day are called harmonic constituents . Conversely, cycles of days, months, or years are referred to as long period constituents. Tidal forces affect the entire earth , but the movement of solid Earth occurs by mere centimeters. In contrast, the atmosphere is much more fluid and compressible so its surface moves by kilometers, in
4800-449: The Moon. Abu Ma'shar discussed the effects of wind and Moon's phases relative to the Sun on the tides. In the 12th century, al-Bitruji (d. circa 1204) contributed the notion that the tides were caused by the general circulation of the heavens. Simon Stevin , in his 1608 De spiegheling der Ebbenvloet ( The theory of ebb and flood ), dismissed a large number of misconceptions that still existed about ebb and flood. Stevin pleaded for

Makati later appealed to the national Department of Education to retain
5300-531: The Sun and moon. Pytheas travelled to the British Isles about 325 BC and seems to be the first to have related spring tides to the phase of the moon. In the 2nd century BC, the Hellenistic astronomer Seleucus of Seleucia correctly described the phenomenon of tides in order to support his heliocentric theory. He correctly theorized that tides were caused by the moon , although he believed that
5400-420: The Sun, Moon, and Earth form a line (a configuration known as a syzygy ), the tidal force due to the Sun reinforces that due to the Moon. The tide's range is then at its maximum; this is called the spring tide . It is not named after the season , but, like that word, derives from the meaning "jump, burst forth, rise", as in a natural spring . Spring tides are sometimes referred to as syzygy tides . When
5500-531: The Two Chief World Systems , whose working title was Dialogue on the Tides , gave an explanation of the tides. The resulting theory, however, was incorrect as he attributed the tides to the sloshing of water caused by the Earth's movement around the Sun. He hoped to provide mechanical proof of the Earth's movement. The value of his tidal theory is disputed. Galileo rejected Kepler's explanation of

South of Cape Hatteras the tidal forces are more complex, and cannot be predicted reliably based on the North Atlantic cotidal lines. Investigation into tidal physics was important in the early development of celestial mechanics , with the existence of two daily tides being explained by the Moon's gravity. Later
5700-429: The amphidromic point. For a semi-diurnal tide the amphidromic point can be thought of roughly like the center of a clock face, with the hour hand pointing in the direction of the high water cotidal line, which is directly opposite the low water cotidal line. High water rotates about the amphidromic point once every 12 hours in the direction of rising cotidal lines, and away from ebbing cotidal lines. This rotation, caused by

In order to make these maps consistent, he hypothesized the existence of a region with no tidal rise or fall where co-tidal lines meet in the mid-ocean. The existence of such an amphidromic point , as they are now known, was confirmed in 1840 by Captain William Hewett, RN , from careful soundings in
7100-415: The idea that the attraction of the Moon was responsible for the tides and spoke in clear terms about ebb, flood, spring tide and neap tide , stressing that further research needed to be made. In 1609 Johannes Kepler also correctly suggested that the gravitation of the Moon caused the tides, which he based upon ancient observations and correlations. Galileo Galilei in his 1632 Dialogue Concerning
7200-468: The interaction was mediated by the pneuma . He noted that tides varied in time and strength in different parts of the world. According to Strabo (1.1.9), Seleucus was the first to link tides to the lunar attraction, and that the height of the tides depends on the moon's position relative to the Sun. The Naturalis Historia of Pliny the Elder collates many tidal observations, e.g., the spring tides are
7300-411: The largest source of short-term sea-level fluctuations, sea levels are also subject to change from thermal expansion , wind, and barometric pressure changes, resulting in storm surges , especially in shallow seas and near coasts. Tidal phenomena are not limited to the oceans, but can occur in other systems whenever a gravitational field that varies in time and space is present. For example, the shape of
7400-570: The late 1960s led the Philippine economy to a sudden downward turn known as the 1969 Philippine balance of payments crisis , which in turn led to a period of economic difficulty and social unrest. With only a year left in his last constitutionally allowed term as president Ferdinand Marcos placed the Philippines under Martial Law in September 1972 and thus retained the position for fourteen more years. This period in Philippine history
7500-620: The major road corridors leading to the city as well as within and at the periphery of the central business district. Poverty incidence of Makati Source: Philippine Statistics Authority The economy of Makati is diverse and multifaceted. Makati is the home to the Ayala Triangle in the Makati Central Business District , which is home to many multinational companies, banks, and other major businesses. A few upscale boutiques, restaurants, and
7600-522: The management of Makati Science High School, Fort Bonifacio Elementary School, and Fort Bonifacio High School, but the city's appeal was denied, leaving the city without a science high school. Rafael Palma Elementary School, which is under the jurisdiction of the neighboring city of Manila 's Schools Division Office , is located in Barangay La Paz, near the Makati–Manila boundary. Makati
7700-419: The moments of slack tide differ significantly from those of high and low water. Tides are commonly semi-diurnal (two high waters and two low waters each day), or diurnal (one tidal cycle per day). The two high waters on a given day are typically not the same height (the daily inequality); these are the higher high water and the lower high water in tide tables . Similarly, the two low waters each day are
7800-412: The month is divided into four parts of seven or eight days with alternating malinae and ledones . In the same passage he also notes the effect of winds to hold back tides. Bede also records that the time of tides varies from place to place. To the north of Bede's location ( Monkwearmouth ) the tides are earlier, to the south later. He explains that the tide "deserts these shores in order to be able all
7900-514: The more to be able to flood other [shores] when it arrives there" noting that "the Moon which signals the rise of tide here, signals its retreat in other regions far from this quarter of the heavens". Later medieval understanding of the tides was primarily based on works of Muslim astronomers , which became available through Latin translation starting from the 12th century. Abu Ma'shar al-Balkhi (d. circa 886), in his Introductorium in astronomiam , taught that ebb and flood tides were caused by
8000-643: The name of the town was shortened to its present name of Makati , under Philippine Legislature Act No. 2390. As of 1934, Makati had 14 barrios according to the Rizal provincial directory, namely: Poblacion , Comandante Carmona , Culiculi (present-day Pio del Pilar), Guadalupe, Fort McKinley , Malapadnabato (present-day West Rembo), Masilang (present-day South Cembo), Kasilawan, Olimpia (Olympia), Palanan, Pinagkaisajan (Pinagkaisahan), Rural, Sampalukan, and Tejeros. Fort McKinley, Malapadnabato, and Masilang were previously parts of Pateros . On January 1, 1942, Makati
8100-618: The nearby Southern Tagalog region, mostly in their twenties, who were abducted in late July 1977 at the Makati Medical Center . Following the assassination of opposition senator Benigno Aquino Jr. on August 21, 1983, Makati became a nexus for protests against the dictatorship of President Ferdinand Marcos . Known as the Confetti Revolution , the demonstrations held in the central business district were led partly by employees of major corporations based in
8200-420: The obliquity (tilt) of the Earth's Equator and rotational axis, the inclination of the plane of the lunar orbit and the elliptical shape of the Earth's orbit of the Sun. A compound tide (or overtide) results from the shallow-water interaction of its two parent waves. Because the M 2 tidal constituent dominates in most locations, the stage or phase of a tide, denoted by the time in hours after high water,
8300-418: The oceans, and the shape of the coastline and near-shore bathymetry (see Timing ). They are however only predictions, the actual time and height of the tide is affected by wind and atmospheric pressure . Many shorelines experience semi-diurnal tides—two nearly equal high and low tides each day. Other locations have a diurnal tide—one high and low tide each day. A "mixed tide"—two uneven magnitude tides
8400-463: The patron of his encomienda "Hacienda Pedro" (now part of the present-day city). Having been named as such, residents corrupted the name to “Sampiro,” which used to refer to both the then-town and its namesake church . Parts of Makati were once subject to the pre-Hispanic Kingdom of Namayan , whose capital is now in the Santa Ana district of Manila . Parts of Makati became a visita of
8500-408: The problem from the perspective of a static system (equilibrium theory), that provided an approximation that described the tides that would occur in a non-inertial ocean evenly covering the whole Earth. The tide-generating force (or its corresponding potential ) is still relevant to tidal theory, but as an intermediate quantity (forcing function) rather than as a final result; theory must also consider
8600-448: The sense of the contour level of a particular low pressure in the outer atmosphere. In most locations, the largest constituent is the principal lunar semi-diurnal , also known as the M2 tidal constituent or M 2 tidal constituent . Its period is about 12 hours and 25.2 minutes, exactly half a tidal lunar day , which is the average time separating one lunar zenith from the next, and thus
8700-465: The seventh city in Metro Manila. The law was approved by a plebiscite one month later, on February 2, 1995, by majority of voters. On May 17, 2000, at 5:02 p.m. PHT , the Glorietta mall located inside the Ayala Center was bombed, injuring 13 persons. According to local authorities, the homemade bomb originated from the restroom of a restaurant and affected an adjacent video arcade. The bombing
8800-500: The solid part of the Earth is affected slightly by Earth tide , though this is not as easily seen as the water tidal movements. Four stages in the tidal cycle are named: Oscillating currents produced by tides are known as tidal streams or tidal currents . The moment that the tidal current ceases is called slack water or slack tide . The tide then reverses direction and is said to be turning. Slack water usually occurs near high water and low water, but there are locations where
8900-584: The southwest by Pasay , and on the northwest by the city of Manila . Creeks such as the Estero de Tripa de Gallina mostly on the west, Maricaban Creek on the south, and San Jose Creek on the east, form parts of Makati's city boundary. Makati has a total land area of 21.57 square kilometers (8.33 sq mi). Its territory also surrounds the Manila South Cemetery , an exclave of San Andres district of Manila . Since November 2023, Makati
9000-401: The subsequent closure of Nielson Field , the town grew rapidly, and real estate values boomed. The first of the planned communities (in what are now the barangays Forbes Park , Urdaneta, San Lorenzo, and Bel-Air established during those times) were established in the 1950s with the efforts of its landowner, Ayala y Compañía . At the same time, Fort McKinley, then renamed Fort Bonifacio , and
9100-436: The then Philippine Army headquarters, became the starting point for the building up of seven more communities by military families who worked in the base area. New office buildings were built on what is now the Makati Central Business District (CBD). Since the late 1960s, Makati has transformed into the financial and commercial capital of the country. In December 1972, two barrios (later barangay) of Makati were established at
9200-643: The then-town of Santa Ana de Sapa in 1578, during the Spanish colonial era . In 1589, Captain Pedro de Brito, then an aide to the Spanish Army chief of staff, purchased a land encompassing the present-day Poblacion with a public bid of 1,400 pesos, and established his encomienda named "Hacienda Pedro". In 1608, he and his wife Ana de Herrera donated half of land to the Jesuits , with the condition of building
9300-433: The tidal movements of the adjacent Pasig River . Alternatively, the word may also mean "itchy", attributed to the lipang kalabaw plant ( Dendrocnide meyeniana ) that once grew in the area. Previously, it was named San Pedro [de] Macati, a name stylized in Spanish . The first part of the name is derived from Spanish for Saint Peter , the then-town's patron saint, chosen by his namesake, Spanish captain Pedro de Brito, as
9400-494: The tides. Isaac Newton (1642–1727) was the first person to explain tides as the product of the gravitational attraction of astronomical masses. His explanation of the tides (and many other phenomena) was published in the Principia (1687) and used his theory of universal gravitation to explain the lunar and solar attractions as the origin of the tide-generating forces. Newton and others before Pierre-Simon Laplace worked
9500-451: The tropics. Its proximity to the equator means that the temperature range is very small, rarely going lower than 20 °C (68 °F) or going higher than 38 °C (100 °F). However, humidity levels are usually very high which makes it feel much warmer. It has a distinct, albeit relatively short dry season from January through May, and a relatively lengthy wet season from June through December. The Global Climate Risk Index 2021 lists
9600-480: The work " Histoire de la mission de pères capucins en l'Isle de Maragnan et terres circonvoisines ", where he exposed that the Tupinambá people already had an understanding of the relation between the Moon and the tides before Europe. William Thomson (Lord Kelvin) led the first systematic harmonic analysis of tidal records starting in 1867. The main result was the building of a tide-predicting machine using
9700-527: Was one of the municipalities of Rizal merged alongside Manila and Quezon City to form the City of Greater Manila as an emergency measure by President Manuel L. Quezon . It regained its pre-war status as a municipality of Rizal when the City of Greater Manila was dissolved by President Sergio Osmeña effective August 1, 1945. After the destruction that the Second World War brought upon Manila, and
9800-605: Was said to be the precursor of the May 21, 2000 SM Megamall bombing and the Rizal Day bombings . On October 19, 2007, an explosion in Glorietta 2 left eleven people dead and injured more than a hundred. Initially, authorities said that it was caused by a liquefied petroleum gas explosion at a restaurant, but later began investigating the possibility that the explosion may have been a C-4 bomb . In April 2022, Makati lost in
9900-548: Was subsequently elected as mayor in 1988. During the 1989 Philippine coup attempt , the Makati central business district was occupied by Reform the Armed Forces Movement forces seeking to overthrow President Corazon Aquino . The resulting standoff lasted from December 2 to 9 and contributed to massive financial losses incurred due to the paralysis in the economic hub. On January 2, 1995, President Fidel V. Ramos signed Republic Act No. 7854, making Makati
10000-609: Was surpassed in 2017 by the Metrobank Center in Taguig with a total architectural height of 318 m (1,043.3 ft). In addition, Evangelista Street in Barangay Bangkal is known for being the site of automobile repair shops, replacement automobile parts stores, tire and wheel stores, car air-conditioning unit repair shops, and car tint stores, almost similar to Banawe Street in Quezon City .
