Truth-Bearer Or "You Can't Handle The Truth"!

A character is a typographic character (printed or written) etc.

A word token is a pattern of characters.

A word-type is an identical pattern of characters.

A meaningful-word-token is a meaningful word-token.

Two word-tokens which mean the same are of the same word-meaning.

A sentence-token is a pattern of word-tokens.

A meaningful-sentence-token is a meaningful sentence-token or a meaningful pattern of meaningful-word-tokens.

Two sentence-tokens are of the same sentence-type if they are identical patterns of word-tokens characters.

A declarative-sentence-token is a sentence-token which that can be used to communicate truth or convey information.

A meaningful-declarative-sentence-token is a meaningful declarative-sentence-token.

Two meaningful-declarative-sentence-tokens are of the same meaningful-declarative-sentence-type if they are identical patterns of word-tokens.

A nonsense-declarative-sentence-token is a declarative-sentence-token which is not a meaningful-declarative-sentence-token.

A meaningful-declarative-sentence-token-use occurs when and only when a meaningful-declarative-sentence-token is used declaratively.

A referring-expression is expression that can be used to pick out or refer to particular entity.

A referential success is a referring-expression’s success in identifying a particular entity.

A referential failure is a referring-expression’s failure to identify a particular entity.

A referentially-successful-meaningful-declarative-sentence-token-use is a meaningful-declarative-sentence-token-use containing no referring-expression that fails to identify a particular entity.

Mont Saint-Michel - A Case Of Syzygy

The Supertide Phenomenon Occurs Only Every 18 Years When Several Astronomical Factors Coincide







A rare astronomical alignment means Britain could face a year of extreme tides and potential flooding along vast swathes of coastline, scientists have warned.

An unusual positioning of the sun, moon and earth has resulted in the gravitational pull on oceans being greater than normal at various points through 2015, creating exceptionally high tides known as "supertides".

This planetary phenomenon will combine with the moon reaching a particular point in the eighteen-and-a-half-year cycle of its elliptical orbit, meaning its gravitational pull will increase as it swings in towards the Earth, also producing higher tides.

Dr Edward Bloomer, an astronomer at the Royal Observatory Greenwich, explained: "If the earth, moon and sun are all in a line - called the syzygy effect – the gravitational push is attractive and we can get more powerful tides than usual.

"When there is a straight line, with the earth at one end, the moon in the middle, and the sun at the other end, this all contributes to pulling the free standing water."

There are expected to be about six periods of so-called supertides, of which three are of particular concern.

The first — around last Thursday — passed without incident.

The next is due on March 21, the Vernal Equinox, and the next on September 23, the Autumnal Equinox.

Dr Bloomer said that while the supertides mainly effect at the highest level of tide, this could "push it over" into a flood.

"If you are in a flooding prone area or if there has been heavy rainfall over the past few days, then this could be the thing that tips it over," he said.

While there are many contributing factors to high tides – the distance between the moon and the earth, the distance between the sun and the earth, and the alignment of the sun, moon and earth - the former remains the dominant factor.

This is due to Newton’s third Law of Motion and Gravity which states that the attractive force between any two heavenly bodies is proportional to the product of the masses and inversely proportional to the square of the distance between them.

Colin Shepherd, deputy head of Tides at the United Kingdom Hydrographic Office, said: "Extreme tidal forces will occur when the moon and sun are in line with the Earth and at their closest respective distances, amplified further when the Moon and Sun have zero declination.

"Extreme tidal forces are prevalent during March/April and September/October, during the Equinoxes."

At these times the Spring tides - generally those occurring two days after the Full or New Moon - are usually significantly larger than usual due to the fact that the Solar Semi-Diurnal forces are maximised.

An Environment Agency spokesperson said: "High astronomical high tides do not lead to coastal flooding alone, it requires a combination of low pressure, strong winds and high tides."

We will monitor the situation closely, working alongside partners, including the Met Office and local authorities, and will issue alerts and warnings if required.

"As always, we would urge people and businesses to sign up to receive free flood warnings and to check their flood risk via our daily flood risk forecast and live Flood Warnings map."

One also needs to consider the tides due to the sun. This gives rise to another semidiurnal constituent, S2, with a period of 12 hours. The interaction or summation, known as beating, between the lunar and solar semidiurnal tides produces a fortnightly modulation with a period of 14.79 days (=1/(wM2 - wS2), where w is used to denote frequency). When the sun and moon are at right angles to each other (in quadrature), you have neap tides, which have relatively small tidal ranges. When the sun and moon are lined up (in syzygy), you have spring tides, which have relatively large tidal ranges.
