The Philadelphia Experiment is a 1984 American science fiction film. It is directed by Stewart Raffill, stars Michael Paré, Bobby Di Cicco, Kene Holliday and Nancy Allen and is based on the urban legend of the Philadelphia Experiment. In 1943, United States Navy sailors David Herdeg (Paré) and Jim Parker (Di Cicco) are thrown forward in time to the year 1984 when a scientific experiment being performed aboard the USS Eldridge suffers a catastrophe. The film follows the two men as they attempt to survive the future and race against time to put an end to the experiment that now threatens the fate of the entire world.
In 1943, United States Navy sailors David Herdeg and Jim Parker serve aboard destroyer escort USS Eldridge, docked in Philadelphia. Doctor James Longstreet and his team conduct an experiment to render the ship invisible to radar, but a malfunction causes the ship to disappear. David and Jim's attempts to stop the experiment fail and they jump overboard to escape.
They land during the night in a small town, which also disappears, leaving them marooned in a desert. Startled by the appearance of an unfamiliar aircraft (a helicopter), they flee and Jim is nearly electrocuted by an electric fence. Eventually, they find their way to a roadside diner. An energy discharge from Jim destroys two arcade games, forcing an altercation with the owner. Fleeing to the parking lot, they take a woman named Allison hostage and force her to drive them away. Confused by their surroundings, they are shocked when Allison tells them that the year is 1984. They are tracked and apprehended by the police. Jim, who is suffering increasingly severe seizures, is hospitalized before disappearing from his hospital bed in a flash of light. David and Allison then evade military police, who have arrived to take David into custody.
Learning that they are near Jim's birthplace, Santa Paula California, David decides to try to find his family. Jim's wife Pamela, who is now a senior citizen, immediately recognizes David from 1943. She says that the Eldridge had reappeared minutes after disappearing. Jim had also returned and had been chastised and hospitalized after telling the truth about temporarily visiting 1984. David finds that he himself never returned. David sees an elderly Jim outside a window but Jim refuses to speak with him. As David and Allison leave, they see military police approaching and a high speed chase through Jim's ranch ensues. The two manage to elude them when the pursuing vehicle crashes and burns. From the burning wreck, David salvages documents mentioning Longstreet. Recognizing that Longstreet had been involved with the Philadelphia experiment in 1943, David decides to find him. As they spend time together, David and Allison fall in love.
In 1984, Longstreet has attempted to use the same technologies that were used in the Eldridge experiment to create a shield as protection from an ICBM attack. When the equipment was tested, the shielded town disappeared into "hyperspace". The scientists are unable to shut down the experiment, which has created a vortex that is drawing matter into it and causes extremely unstable and severe weather. Longstreet predicts that the vortex will continue to expand until the entire world is consumed. The scientists send a probe into the vortex and discover the Eldridge inside. They theorize that the two experiments have linked together with the generators on the Eldridge powering the vortex.
David captures an assistant at Longstreet's home and forces the man to take them onto the base. Longstreet explains the situation to David and tells him that, according to surviving sailors from the Eldridge, the ship returned to Philadelphia in 1943 after David shut down the generator. Longstreet says that David must go through the vortex to the Eldridge and terminate the experiment or the vortex will destroy the Earth.
David is outfitted with a protective suit to allow him to shut down the experiment and catapulted into the vortex. He lands on the deck of the Eldridge, where he finds crew members badly injured. He hurries to the generator room and smashes arrays of vacuum tubes using a firefighting axe. The generator shuts down and David looks for Jim. Assured that Jim is fine, David jumps over the side of the ship and disappears. Back in 1943, Longstreet and others watch the Eldridge reappear in Philadelphia, revealing crew members with severe burns, while others have been fused alive into the ship's hull.
In 1984, the missing town reappears as Allison and David are reunited.
John Carpenter wrote an original draft. He called it a "great shaggy dog story. Absolute crap, but what a great story. While I was writing it, I couldn’t figure out the third act. A friend suggested the revenge of the crew against the people who put them there, but I thought it was too much like The Fog".[2]
Stewart Raffill says by the time he became involved with the film, the script had been rewritten nine times. He agreed to do the film, subject to the next rewrite which he thought was "terrible". The head of the studio agreed with Raffill's additions to the script, even though it was only three weeks before filming: "So, he asked if I had ever dictated a screenplay before. I told him I had not. Then he said, ‘Well, I’m gonna send someone to your house, a girl, every afternoon, and just dictate the story you told me and fill in the dialogue and we’ll make that.’ And I said, ‘Okay.’ So that's what I did."[3]
A simple equation relates wavelength and frequency to the speed of the wave.
The wavelength to frequency and frequency to wavelength calculations are important in physics and engineering. Here is the equation relating wavelength and frequency, example calculations, and a table of common values.
Relationship Between Wavelength and Frequency
A simple equation relates wavelength to frequency:
v = λf
v = wave velocity (how fast the wave propagates in a medium)
λ = wavelength (distance over which a wave shape repeats)
f = wave frequency (number of waves per unit of time)
For light and other electromagnetic radiation in a vacuum, the wave velocity is the speed of light (c):
c = λf
But, the wave speed is different for other kinds of waves and for light passing through a medium.
Light in air or vacuum: 299,792,458 meters per second
Light in water: 224,901,000 m/s
Sound in air: 343.2 m/s
Sound in water (20 °C): 1,481 m/s
Wavelength and frequency are inversely proportional. As wavelength increases, frequency decreases. As frequency increases, wavelength decreases.
How to Calculate Wavelength From Frequency
Rearrange the equation and calculate wavelength from frequency:
λ = v/f
For example, find the wavelength of the musical note A4, which has a frequency of 440 Hz.
The only tricky part in the calculation is keeping the units straight. Usually, you work with meters and Hertz and then convert to other units (e.g., nanometers, THz, GHz). In this problem, the wave velocity is the speed of sound in air (343.2 m/s). The frequency is 440 Hz. One hertz unit equal one cycle (wave) per second, so a frequency of 440 Hz is 440 s-1.
λ = v/f λ = (343.2 m/s)/(440 s-1) λ = 0.78 m or 78 cm
As another example, find the frequency of the green light of the aurora borealis, which has a frequency of 5.38 x 1014 Hz.
Here, the equation is:
λ = c/f λ = (3 x 108 m/sec)/(5.38 x 1014 s-1) λ = 5.576 x 10-7 m = 557.6 nm
How to Calculate Frequency From Wavelength
Rearrange the equation and calculate frequency from wavelength:
f = v/λ
For example, find the wavelength of orange light with a frequency of 4.8×1014 Hz.
f = v/λ (but v is c for light) f = c/λ f = (3.00 × 108 m/s)/(4.8×1014 s-1) f = 6.2 x 10-7 m = 620 nm

PATRICK DOYLE / THE CANADIAN PRESS
OTTAWA—Actor Michael J. Fox is now an officer of the Order of Canada.
The Edmonton-born actor and activist is among 43 people who received their medals from Gov. Gen. David Johnston at a Rideau Hall ceremony.
Others include rock legend Robbie Robertson, hockey commentator Howie Meeker, Acadian filmmaker Phil Comeau, former cabinet minister Anne McLellan and Trudeau biographer Stephen Clarkson.
Fox was honoured for his efforts on behalf of those suffering from Parkinson’s disease, as well as his television and film work.
Fox, diagnosed with Parkinson’s two decades ago, called the award a great honour.
He chuckled that he felt like an imposter when he glanced around at his fellow inductees.
“I don’t begin for a second to put myself in the league of any of these people,” he said. “When I listen to what they’ve done, that’s Canadian to me. It’s a seriousness and a sense of humour, it’s a lot of contradictions.”
He said Canada always makes him think “of vast spaces and tight communities.”
“We think of ourselves huddled against the elements and helping each other. It’s very moving to be part of it.”
Modo IA Todo Imágenes Vídeos Noticias Maps Shopping Libros Vuelos Finance The connection linking all of these elements is a web of esoteric historical timelines, alternative history theories, and symbolic numerology centered heavily on the date October 28th. While mainstream history views these as separate events, occult researchers, alternative historians, and conspiracy theorists connect them through recurring astrological alignments, geographic coordinates, and sacred geometry. Here is how each element connects to this overarching matrix: 1. October 28, 1492: Columbus and Cuba The Event: Christopher Columbus officially landed in Cuba on October 28, 1492, claiming it for Spain. The Esoteric Connection: Alternative historians note that Columbus was heavily influenced by biblical prophecy and eschatology. Some theorists argue his voyage was timed according to specific astrological windows, making October 28 a foundational date for the "New World" ritual alignment. 2. Feast of Saint Simon and Saint Jude (October 28) The Christian Calendar: In the Catholic liturgical calendar, October 28 is the feast day of St. Simon the Zealot and St. Jude Thaddaeus. The Connection: Saint Jude is famously known as the patron saint of lost causes and desperate situations, while Simon is associated with political zeal. In esoteric circles, launching major historical events (like Columbus's landing) on this specific feast day is believed to invoke specific spiritual or symbolic protections. 3. The Philadelphia Experiment and Atlantis The Philadelphia Experiment: This famous military myth claims that on October 28, 1943, the US Navy destroyer USS Eldridge was rendered completely invisible and teleported from Philadelphia to Norfolk. The Atlantis Link: Writers like Charles Berlitz (who popularized the Bermuda Triangle) tied the technology used in the Philadelphia Experiment (magnetic fields, space-time manipulation) to ancient, lost technologies of Atlantis. Furthermore, some psychic traditions (like Edgar Cayce's readings) claim that Atlantean technology caused the destruction of their continent, drawing a parallel to the disastrous space-time rift alleged in 1943. 4. The Statue of Liberty The Dedication: The Statue of Liberty was officially dedicated in New York on October 28, 1886. The Connection: Designed by Frédéric-Auguste Bartholdi and championed by Gustave Eiffel (both prominent Freemasons), the statue represents Libertas, the Roman goddess of freedom. Esoteric researchers view the dedication on October 28 as a deliberate choice to align America's ultimate symbol with the same date as Columbus's landing, anchoring a specific timeline matrix. 5. The Da Vinci Code Connection The Templar Lineage: Dan Brown’s The Da Vinci Code popularized the lore of the Knights Templar, the Holy Grail, and hidden sacred lineages. The Connection: Secret society lore often links Christopher Columbus to the Templars (pointing to the Templar crosses on his ship sails). Furthermore, the Priory of Sion mythos heavily utilizes sacred geometry and specific dates. October 28 acts as a "key" date where various global alignments—from the discovery of America to the anchoring of Masonic monuments like the Statue of Liberty—intersect. 6. The Flag of Israel Sacred Geometry: The Flag of Israel features the Hexagram (the Star of David / Seal of Solomon) between two horizontal blue stripes. The Connection: In Western occultism, the Seal of Solomon is the ultimate symbol of "As Above, So Below"—the merging of the spiritual and physical worlds. This geometric harmony is what ties all these events together: the date (October 28), the monuments (Statue of Liberty), and the alleged portal experiments (Philadelphia) are all claimed by alternative theorists to be calculated using the exact same hermetic and geometric principles represented by the hexagram.

Modo IA Todo Imágenes Vídeos Noticias Maps Shopping Libros Vuelos Finance 9 sitios There is no official historical or Masonic link connecting the Jewish fast of Tisha B'Av (9th of Av), Argentina’s Independence Day (July 9th), the Buenos Aires Obelisk, and The Da Vinci Code. These connections exist purely within the realm of speculative esotericism, internet conspiracy theories, and creative wordplay. Here is a breakdown of how these separate concepts are intertwined in alternative theories, analyzed through the lens of history and esoteric symbolism. 1. The 9 of Av (Tisha B'Av) vs. July 9th In speculative gematria and calendar syncretism, conspiracy theorists occasionally link these dates due to the identical numbers (9/9). Tisha B'Av (9th of Av): This is the most somber day in the Hebrew calendar, mourning the destruction of the First and Second Temples of Jerusalem. Because Masonic lore borrows heavily from the construction of King Solomon’s Temple, esoteric thinkers sometimes fixate on the 9th of Av. AMIA | Comunidad Judía +1 July 9th: This date marks Argentina's Declaration of Independence in 1816. While many Argentine founding fathers (like San Martín or Belgrano) belonged to prominent political lodges like the Logia Lautaro, the date was chosen for political reasons, not to align with a shifting lunar Jewish fast. 2. The Buenos Aires Obelisk and Freemasonry The Obelisk of Buenos Aires is frequently cited in esoteric urbanism. Wikipedia Masonic Imagery: In architectural esotericism, an obelisk represents a ray of the sun, the generative force, and the connection between the earthly and divine realms. Perfil +1 The "Masonic Triangle": The Obelisk sits on Avenida 9 de Julio. Urban myths claim that the layout of Buenos Aires avenues—pioneered by Mayor Torcuato de Alvear (a Mason)—forms geometry pointing to key government buildings, mimicking Masonic spatial planning seen in Washington D.C. or Paris. However, the Obelisk itself was designed in 1936 by modernist architect Alberto Prebisch to commemorate the city's 400th anniversary, not as an explicit Masonic temple. Diario El Día de La Plata +2 3. The Da Vinci Code Connection: The "A" and "V" Your mention of "the A and the V" points directly to the gender-essentialist geometry popularized by Dan Brown’s The Da Vinci Code: The Blade and the Chalice: In the novel, the upright triangle (▲ or A) represents the "Blade"—the masculine phallus, a symbol of fire and aggressive male energy. The inverted triangle (▼ or V) represents the "Chalice"—the feminine womb, the Holy Grail, and water. The Obelisk connection: In this specific symbolic framework, the Obelisk is the ultimate architectural "Blade" (A). The Linguistic Coincidence: Conspiracy theorists love to point out that the abbreviation for "Avenida" is Av., making the address of the Obelisk look like "Av. 9 de Julio." They merge the Hebrew month Av with the abbreviation Av., using the A and V letters as a visual shorthand for the union of the masculine blade (the Obelisk) and the feminine chalice (the wide avenue or surrounding valley). 4. The Key of David The Key of David is a biblical concept (Isaiah 22:22, Revelation 3:7) symbolizing absolute authority to "open what no one can shut." In esoteric traditions, it is sometimes conflated with the Hexagram (the Star of David, which is a interlocking combination of the A and V triangles). Conspiracists tie this back to the Obelisk by claiming such monuments act as literal or spiritual "keys" keeping cosmic currents locked into a city's grid. Summary of the Theory vs. Reality Element Real Historical Context Esoteric / Conspiracy Interpretation 9 of Av / July 9 Lunar Jewish fast / Solar Argentine independence day. A numerical sync (9/9) marking temple destruction vs. nation building. The Obelisk 1936 Civic monument by Alberto Prebisch. A phallic Masonic "Blade" (A) channeling solar energy. Av. 9 de Julio A massive infrastructure project named after a date. A deliberate play on the word "Av" and the A/V gender symbols. The Key of David A theological symbol of sovereign divine authority. The architectural layout acts as an occult key to power. Ultimately, while Freemasonry has heavily influenced the architecture and founding history of Buenos Aires, the specific bridge linking Tisha B'Av, The Da Vinci Code geometry, and July 9th is a modern, pop-culture tapestry woven out of coincidence and symbolic wordplay.
