navigational aid



There’s something strange in the air where the Catatumbo river flows into Lake Maracaibo. For 260 nights of the year, often for up to 10 hours at a time, the sky above the river is pierced by lightning, producing as many as 280 strikes per hour. Known as the relampago del Catatumbo (the Catatumbo lightning), this everlasting lightning storm has been raging for as long as people can remember.

The lightning, visible from 25 miles away, is so regular that it’s been used as a navigation aid by ships and is known among sailors as the Maracaibo Beacon. Recent scientific studies have determined that the concentrated lightning is likely caused by an air current that sweeps moisture from the Caribbean Sea and drives it up above the lake. Climate research scientists are currently using Catatumbo as a testing ground to trial a lightning forecast system.

Castle Hill Lighthouse is located on Narragansett Bay in Newport, Rhode Island at the end of the historic Ocean Drive. It is an active navigation aid for vessels entering the East Passage between Conanicut Island and Aquidneck Island. The lighthouse was completed in 1890 on property formerly belonging to the naturalist, oceanographer, and zoologist Alexander Agassiz of Harvard University. Agassiz sold the land to the United States Government for the lighthouse for $1.00.

I would like to propose a new term

disability parkour- compound noun, /dɪsəˈbɪlɪti/ /pɑɹˈkʊɹ/ 
1. The method by which physically disabled people who don’t have their mobility aid navigate their environment, including leaning on things, sitting down on things, asking pedestrians for help, and so on.
2. General- the ways in which all disabled people navigate an environment that is unfriendly for them. 

If you do a particularly skilful feat of disability parkour, post it in the #disability parkour tag so I can cheer you on. :) 


Fort Carroll (Sparrows Point, Maryland) 

ADDRESS: Sparrows Point, Maryland 21219

CORRDINATES: 39.214593, -76.519078

In 1847, the State of Maryland gave permission to the United States War Department to construct a fort in the shallow water of Soller’s Point Flats to protect the city of Baltimore. This fort was named Fort Carroll and was important for the defense of Baltimore. In 1853 a lighthouse was built on the ramparts to aid navigation into Baltimore Harbor and in 1898 a new lighthouse was built. The Fort was there for the Civil War, the Spanish-American War, and World War I. 

After World War I broke out, the Army removed the guns from the fort and by 1920 all guns were gone. In March 1921 the Army officially abandoned Fort Carroll and moved whatever military equipment was left to nearby Fort Howard. The War Department declared the island excess property in 1923 but took no immediate steps to sell the land. In World War II the Army used the fort as a firing range. It also served as a checkpoint for vessels.

In May 1958, Baltimore attorney Benjamin Eisenberg purchased the island for $10,000, intending to put a casino on the island, but development plans never materialized. The fort is now abandoned has is the home of thousands of native birds. 

Apollon Festivals

The Seventh day of each month was celebrated as a feast day in honor of Apollo. 

Boedromia was held on the the seventh day of Boedromion (September 21st, 2015) to thank Apollo for his aid to Athens. 

Carneia was a Spartan festival held the 7th thru the 15th of Metageitnion (August 22nd - 30th, 2015). Military operations were suspended during Carneia. The festival was held in honor of Carneus, who was a favorite Seer of Apollo’s, who was slain by a Heraclidae. 

Daphnephoria was held every nine years in honor of Apollo, in Thebes. A young man or boy in good standing lead the procession, dressed in finery with laurels on his head, carrying an olive branch wrapped in purple and saffron ribbons and decorated with bronze orbs to represent the Sun, Stars, and Moon. (“Daphnephoria”. Encyclopædia Britannica 7 (11th ed.))

An Athenian festival held in honor of Apollo and Thesus’ prayers to him before he set off to slay the Minator is Delphinia. Held on the seventh day of Mounykhion (April 26th, 2015), Delphinia consisted of offerings to Apollo for aid in navigation and safe travels over seas.

Lasting three days in Hekatombaion (~July), Hyacinthia was held in honor of Apollo’s lover Hyacinthus. The first day was held in honor of Hyacinthus’ death, and offerings were made to the dead. The second day was full of feasts, celebrations, and competitions of song in honor of Apollo. Citizens and foreigners were both welcome to participate. The third day has not been described historically in much detail, and scholars speculate that it was a day for mystery rites. (Michael Pettersson, Cults of Apollo at Sparta: The Hyakinthia, the Gymnopaidiai, and the Karneia, Paul Åströms Forlag, Stockholm, 1992)

Pyanopsia was held in honor of Apollo as a sun God and ripener of fruits, where offerings were made to him and the Horea during the seventh day of Pyanepsion (October 20th, 2015). A branch wrapped in purple or white wool and adorned with season fruits, jars of honey, and jars of oil was made as an offering to Apollo in thanks for blessings received and to ask for protection from evil. Doors could be similarly adorned, or else the offering branch hung for protection, and left for the year.( “Pyanepsia”. Encyclopædia Britannica 22 (11th ed.))

Held on the sixth and seventh days of Thargelion (May 24th and 25th, 2015) Thargelia honored Apollo and Artemis. Sacrifices were made to Apollo and Artemis, as well as a sacrifice to Demeter to promote a fertile growing year. A purification ritual was held on the first day of the festival. On the second day, choir festivals were held and adoptive members of a family were formally welcomed into the family.

First Night Attack on London by Airplane

May 6 1917, London–German Zeppelins had repeatedly bombed London by night in 1915 and 1916.  The British had begun to intercept Zeppelins by airplane on a regular basis, however, resulting in multiple Zeppelins shot down.  In response, the Germans tried refitting their Zeppelins to operate from a higher altitude, but so far had had little success, encountering strong winds at 16,000 feet that prevented reliable navigation.

The Germans had bombed London by airplane on at least one occasion so far, and were planning more organized raids in future.  Such operations had been, and were planned for, the daytime, to aid in navigation and target selection.  Of course, this would also make it easier for the British to intercept them.  As a proof of principle, the crew of an Albatros C VII decided they wanted to try bombing London at night time.  They were given permission to do so, and on the night of May 6, they dropped six 22-lb bombs between Hackney and Holloway, killing 1 civilian and wounding two others, before successfully returning to occupied Belgium after a four-hour round-trip flight.  This was the first night-time attack by plane on London; they were able to find their way using the full moon and the easily-identifiable Thames.

Higher authorities in German air command were displeased at this solo raid, however.  They had been planning to begin major (daylight) bombing raids on London with new Gotha bombers later in the month, and were worried that this attack might spoil the surprise.

We’ve got your weekend inspiration! #DiscoverTheCoast with us in California

The California Coastal National Monument preserves important habitat for coastal plants and animals, and protects cultural sites that provide insight into the people who lived along the California coast thousands of years ago. Many of the new units of the monument are also culturally and spiritually important to local tribes.

Cotoni-Coast Dairies

This portion of the California Coastal National Monument encompasses ancient archaeological sites, riparian and wetland habitats, coastal prairie grasslands, and woodlands that include stands of coast redwood. Photo by Jim Pickering, BLM. 

A respite from the modern world, complete with historic architecture and abundant natural life, awaits visitors to the California coast at Piedras Blancas.

Only 40 miles north of San Luis Obispo, California, the large white coastal rocks for which Piedras Blancas was named have served as a landmark for centuries to explorers and traders along the central coast of California.

Built in 1875 as a safety aid to mariners, the light station once cast a flashing, oil-flame light 25 miles out to sea, warning ship captains to steer clear of the white rocks that would mean certain doom for a vessel.

Today, the light station, its first order lens and light structure long ago removed, casts a beacon to travelers on scenic California Highway 1. It continues to provide a navigational aid to ship traffic, as well. Photo by David Ledig, BLM.

ov33  asked:

Does lighthouse point have a lighthouse?

Good question! Lighthouse Point Certainly contains a round tower, but is it really a lighthouse?

The definition of a lighthouse is “is a tower, building, or other type of structure designed to emit light from a system of lamps and lenses, and to serve as a navigational aid for maritime pilots at sea or on inland waterways.” 

The round structure at Lighthouse Point is certainly geographically positioned near the sea, which would suggest that it is indeed a lighthouse. However, since the player cannot enter the structure, and no point in Konikoni City gives a perspective to see the top of the structure, we cannot confirm that the tower is outfitted with an light-emitting system and therefore the question remains uncertain.

The Olivine Lighthouse in Johto is operated by an electric-type pokémon Ampharos. At Lighthouse Point in Alola, the player encounters a woman training several Pikachu, perhaps preparing them to operate the supposed lighthouse.

Thanks for your question!

Day 19: Favourite Fan Art

Trashcans are art, especially this one.

This could have easily echoed yesterday - seeing our world reimagined by so many hands, in so many different ways, in so many mediums is a joy. Some are just stunning…

…but this fellow sits on my desk next to my David Lafuente art, stares at me, and helps in a small way. There’s a writer thing that, to avoid losing the core of your work, you put the themes on curt post-it note and stick it to your monitor, so every time you glance up you’re reminded of what the story actually is. It’s a magnetic north, and you stick to it if you’re lost.

This is like that, but providing a more limited navigational aid, reminding me that Woden is fucking trashcan.

Never forget, Kieron. And thanks to this little fella, I won’t.

The Challenge.

dirty-lake-mermaid  asked:

Isn't a beard uncomfortable on your adventures? I'm just curious :)

My beard serve a lot of purposes in the wilderness:

  • It keeps my face warm.
  • It protects my face from sunburn; windburn.
  • It protects my face from mosquitoes and other pests.
  • It allows me to detect wind direction, aiding in navigation.
  • Food gets stuck in it, providing emergency rations.

I’m sure that it would serve many other purposes too, I just haven’t discovered them yet.


The Swapper Coming to PS3, PS4, PS Vita in May

Our final PlayStation game announcement of the month is something I’ve wanted to talk about for a really long time. I’m now very happy to be able to tell you about our plans to bring the critically acclaimed puzzle-platformer, The Swapper, to PS3, PS4 and PS Vita this year.

The Swapper was released in 2013 on PC, and has had some amazing press coverage. It won numerous awards in the indie gaming scene for its story, graphics and puzzle design. We’re very lucky to be working with original developer Olli Harjola to bring the game to PlayStation formats, and the game is already looking beautiful on our PlayStation systems here at Curve towers, so we think you’re in for a real treat.

The Swapper is set on Theseus, a damaged space station and research facility. It’s a claustrophobic, dark, and atmospheric environment, but it’s also very unique in style — there’s no blocky pixel art and digital textures in this game, but instead handcrafted art and clay models designed by the original developers.

These real world props make up the many different environments in the game and provide The Swapper with an art style that feels realistic and is dripping with tons of detail. This is a game where the environment tells a story every bit as much as the dialogue in the game, so we’ve been working very hard at Curve to make sure each version we make looks and sounds perfect.

As for the game itself, it’s your job to search for a way off Theseus station, a (mostly) abandoned, self-sustaining outpost in deep space. I won’t spoil the plot here, but The Swapper has some themes and stories every bit as dark as the games environment, and it’s very satisfying to play through. To aid your navigation in the station, you’re able to create up to four clones of yourself and can switch between them at will in order to solve a huge variety of clever puzzles.

We’ll be talking about the game in a bit more depth over the next few months, but we should be releasing The Swapper in late May this year, so if you’re into puzzle games, science-fiction, or just want to try something really unique, keep an eye out for this one!

      Quantum network would be most precise clock yet

      Physicists propose harnessing ‘quantum entanglement’ to surpass accuracy of any single atomic clock.

      By exploiting the tricks of quantum physics, researchers say they could build a worldwide network of atomic clocks that are much more accurate than any single clock in existence today.

      This global hook-up would enable countries to synchronize timekeeping standards and improve space navigation. It could also aid the exploration of fundamental physics concepts, such as the long-sought gravitational waves thought to be rippling through space and time.
