The Movie “Jaws” Foreshadowed America’s Disinformation Crisis

If you want to talk about disinformation in America, “Jaws” is one of the best examples of how a simple story based on a false fear can do exceptional long lasting harm.

It is very difficult to get sharks back to what they are, correctly seen as loving and affectionate.

An example of shark reality is from 1959 to 2010 the TOTAL number of fatalities was 26 in America (0.5/year average). Only 1 in a 3.7 million chance.

For an obvious comparison in risk homeostasis, lightning data shows a 37.9/year average. That average means 1 in 180,746 Americans will be killed by lightning. And that actually is less likely even than being killed by a dog, which is 1 in 118,776!

Ok, to be fair American citizens killed by anything means we take the population total and divide by recorded deaths. The resulting number really shouldn’t be substituted for a probability because factors creep in.

Do you swim every day with sharks? Things like that make better factoring for probability.

Speaking of swimming with sharks then, here is another example of shark reality, as written by Sune Nightingale:

On a dive one day Cristina Zenato noticed a hook inside a shark’s mouth. In the end she just stuck her hand in and pulled it out. From that moment on the shark changed her behaviour and would show up on the dive and allow Cristina to stroke her, and would give Cristina a little nudge on the hip as if to say “hey I’m here”

Then other sharks started showing up wanting hooks removed…..Cristina now has a box of over 300 removed hooks.

“This is a wild animal and she’s giving me full trust…….It is something to be absolutely in awe of no matter how many times it happens …..what I developed is an appreciation for their vulnerability.”

Really changes your perception of sharks doesn’t it to see one being so cuddly and kind?

Again the odds of an American being killed by shark are about 1 in 3.7 million for everyone in the general population. It’s super remote on a generic predictive scale prone to error.

Yet here we see the odds of being killed by a shark actually even MORE remote, reaching towards zero for someone swimming with them constantly. They seem to love her and trust her.

The author of Jaws expressed his deep regrets for writing such a dangerous fiction, but obviously it did little to change the disinformation effect of his book and the movie.

“Spielberg certainly made the most superb movie; Peter was very pleased,” Wendy Benchley told Associated Press. “But Peter kept telling people the book was fiction, it was a novel, and that he took no more responsibility for the fear of sharks than Mario Puzo took responsibility for the Mafia,” she said, referring to Puzo’s screenplay and novel “The Godfather.”

“Jaws” was “entirely fiction,” Peter Benchley repeated in a London Daily Express article that appeared last week.

“Knowing what I know now, I could never write that book today,” said Benchley, who also co-wrote the screenplay for “Jaws.” “Sharks don’t target human beings, and they certainly don’t hold grudges.”

Americans target sharks and hold grudges against them. Not the other way around.

The Future-Future of Aircraft Carriers

The impressively huge Aircraft Carrier was a decisive platform in past wars and still gets a lot of airtime (pun not intended).

…when word of a crisis breaks out in Washington, it’s no accident that the first question that comes to everyone’s lips is: ‘where’s the nearest carrier?’

However, I can’t help but think about it in terms of a commoditization line over history.

What I mean to say is that there is a line that goes from the 1960s drone war being conducted on a mainframe in a few high-security buildings, all the way to warfare today being done using mobile phones in everyone’s pocket.

Take the core concept of the “carrier”. In today’s commodity technology terms I believe you get an autonomous sea box of tiny drones ready to swarm.

One of the lessons of the 1980 failed operation Eagle Claw, for example, was they came up one single aircraft short of a complete mission.

Imagine telling that story instead where the numbers of aircraft launched from sea are no hurdle at all — opposite problem really, as you have surplus of highly operational units.

The sea launch platform already was pioneered a while ago by submarines launching drones out of their missile tubes. And the Navy many years ago was manually launching swarms of 50 drones. Surely by now they’ve combined these two advances into tubes at sea having a magazine attached.

Now flatten the carrier to waterline (e.g. into a Low Visibility Craft or LVC) to remove its target profile, and with a towline attach a submarine filled with sensors and tubes of hundreds or thousands or drones.

It would look like a fatter version of the 2016 Wave Glider submersible by Liquid Robotics.

Obviously this means surface vessels could easily reload by picking up another tow-line submersible, bringing resupply buoys (forward docking stations) into the picture on “long line” deployments.

Also I can’t help but mention this is very similar to what was being designed in the late 1800s and even demonstrated by Tesla himself, so we’re on a very late cycle of adoption (postponed by WWI emphasis on maintaining control over petroleum distribution).

The drones could launch undersea or on surface. Either way it’s a far more modern take on an old solution, for an even older problem in warfare.

Forensics on America’s “Patriot” platform crash

Nobody cares about sailing but if you’re nobody… I’m happy to explain exactly why “Patriot” is a great metaphor for American extreme-right politics:

Winless and when it starts to get ahead it self-destructs from easily predictable yet careless abuse of power. Did you know “Patriot” platform was a thing?

Now here is a video with some great detail on America’s “Patriot” platform crash disaster.

And here is the aftermath captured by photographers on the scene, just before it started to take on water and sink…

Nautical forensics notables:

1) Americans are flying Airbus. I feel like I just have to say that because in the video it’s a very prominent sponsor sign. This is basically a plane turned sideways with one wing-set in the air and one wing-set below water (different medium density explains the size difference)

2) British Olympic champion “Goody” Goodison warns American Barker he sees unsafe pressure levels so slower transition (more room for error) recommended, overruled by Barker.

3) The leward backstay/runner sticks, pins the square-top main and in high gust launches the boat to 50 mph then flips it sideways and drops on its fragile side

Who Was The Pirate? Curious Case of Blackbeard’s Murder

A site called Coastal Review has a fascinating take on the events that led to Blackbeard’s untimely violent death.

Blackbeard did not prey on a single ship in the waters off the Outer Banks during his surprisingly brief 23-month career as a pirate. And, as previously stated, his pitiful camp at Ocracoke and pirate company of 15 men were hardly a threat to anyone.

[…]

Blackbeard and his friends from Bath, many of whom were killed, were unwitting pawns caught in the middle of what turned out to be a failed political coup.

Furthermore, Lt. Maynard’s 60 Royal Navy sailors acted as little more than pirates themselves.

Hao Projection: Chinese-Drawn World Map

Maps are political by nature of defining boundaries. Whoever has that authority to classify territory, gains a lot of power.

More interesting than just drawing the lines, however, is the graphical representation of 3D spaces in 2D. Many probably are familiar with the impact of the Gall-Peters map (by Arno Peters based on a 1885 James Gall paper) since the 1980s.

UNESCO promotes the use of the Gall-Peters projection, and this option is widely used in British schools. Boston became the first public school district in the United States to adopt this map as its standard in 2017.

Lately it seems like the Gall-Peters projection opened the door to dynamic maps that try re-frame our understanding of reality in terms of coastline length.

Speaking of coastlines, a report in 2010 by Linda Jakobson at the Stockholm International Peace Research Institute called “China Prepares for an Ice-Free Arctic” shows China’s perspective on sailing through the Arctic.

Then on 11 December 2013 the Chinese Academy of Sciences announced that the researcher (geophysicist) Hao Xiaoguang had drawn another new map of the world.

…with the authorization of National Administration of Surveying, Mapping and Geoinformation. Traditional word map is suitable for expressing the relationship of east and west hemisphere, it uses meridian to cut the global and should be called as merdian-wise world map. As contrary, the new version of world map uses prime vertical to cut the global and should be called as prime vertical-wise world map, consequently, it is suitable for expressing the relationship of north and south hemisphere. In order to express the geography relationship properly, the workshop had proposed the design scheme of series of word map since 2000 to 2002. In recent years, the new version of world map had been applied by many agencies for different scientific purpose, and the draft has been collected by State Museum, From now on, the new word map will be available in our daily life and will give us brand new geography idea.

Saying prime vertical-wise world map is a mouthful (maybe sounds better in Chinese?) and so the Hao Projection might be easier and make more sense.
