Perfidious J00z Are Ruining the Legacy of Stan Lee and Jack Kirby!!!

It’s been a few years since I’ve written a post about assholes being enraged about Marvel’s Thor. These creeps lost their part-time minds when a female iteration of Thor appeared in a comic book. Now, they are feeling the same angst over an upcoming movie in which Thor is a lady. Some of them are, as is distressingly fascionable today, blaming the Jews for emasculating Thor. Oh, the perfidy! Why must the Jews disrespect the legacy of Stan Lee and Jack Kirby?

Something tells me that most of these whiners have never read the original Norse source, or they wouldn’t be so upset about Thor in a dress.

POSTSCRIPT: Weird, all of the links seem to be broken, but the html coding looks okay. I will post links to the current outrage in the comments.

Meanwhile, Back on Earth

This weekend, I found myself the victim of a Chinese hoax. Put succinctly, it’s been hot as balls. Today, the mercury hit 98, with the humidity making it feel like 105. I tried to limit my outdoor time, but my job involves spending quite a bit of time outdoors, so I coped by drinking a lot of cold water before stepping outside. Still, each day I sweat through a couple of shirts. It was a relief each day when everyone else went home, and I could sit in my office without a shirt. The dress code, like the hospitality standards, goes to hell at a certain time of night.

The heat wave is finally subsiding, as a cold front is moving in, bringing rain. I’ll be off tomorrow while the promised rainstorm hits its full fury. Given the conditions I worked under all weekend, I’ve got a bunch of musty smelling shirts to launder.

After Fifty Years, What Are We Achieving?

I enjoyed the Google doodle celebrating the fiftieth anniversary of the first moon landing, narrated by Michael Collins himself. The Apollo 11 mission occurred shortly after I was born, the day of my christening... family lore has it that some of the attendees were glued to their car radios in the parking lot until they were told to get in the bleepin' church already! I've written a bunch of posts about the moon- musings over the celestial body's beauty, science posts, posts about the Apollo missions themselves. I work nights, the moon literally looms over me much of the time.

That world of fifty years ago seems remote... sure, while the Apollo missions themselves were peaceful, an achievement for humanity as a whole, secondarily an achievement for Americans, the United States was involved in bombing peasants to oblivion in Southeast Asia at the time (the Mekons pointed out this contradiction). The plaque left on the moon by Neil Armstrong and Buzz Aldrin is a beautiful bit of prose, but the mission didn't herald an era of peace:

Rather than heed the Call to Adventure, the excitement of discovery, humanity's leaders decided to become bogged down in greed, fundamentalism, superstition, and tribalism. What should have become a Grand Mission for All Humanity soured, and petty, parochial concerns came to preoccupy Homo sapiens. Scientific inquiry takes a backseat to distortions of data to push corporate agendas, government policies subsidize fossil fuel extraction rather than the development of clean, renewable energy sources. Monkey trials are conducted, flat earthers push their nonsense on social media platforms. I think that, by nature, I tend to be an optimist, but the empirical evidence that has confronted me for the entirety of the twenty-first century causes me to have flashes of pessimism. I'm not the kind of person who dwells on concepts like the Fermi Paradox, but fifty years after one of humankind's most lofty achievements, it seems as if our species is slowly sliding to stagnation, and possible destruction, so that a tiny majority of the Worst Persons on the Planet can engage in an overconsumption that will eventually consume us all.

American Dream, American Nightmare

I have been in a foul mood all evening, and it's not due to the fact that I sweat through three shirts over the course of the workday. We had a lovely event, a dinner for a cadre of visiting teachers who have been at a workshop all week. The president of the organization attended, as did the head of HR and another vice president. Assorted other mucky-mucks were also present. Because we had a crowd of almost fifty attendees, we needed a cleaning contractor present to make sure the bathrooms were cleaned and stocked, and to assist in getting the post-dinner trash out to our dumpsters.

Tonight, our cleaning contractor was my Chilean friend, whose mother brought her here three years ago so she could pursue a STEM education. She's a vivacious young woman, quick with a joke or an anecdote. When there was a lull in the workday, while all of the guests and VIPs were dining, she told me that she had had a nightmare... it was a nightmare specifically about ICE. Her family had gotten a visa extension, but still felt tension about the process going through. She told me that her mother had instructed her not to answer the door, not to talk to strangers, and to dress in her best clothes when she was in public. She recounted how, when she came to the US, she was shy, but that her confidence had grown as she learned English and started to take honors classes. Now, her confidence had been shaken. She came here to study, to learn, to live up to her limitless potential.

Luckily, one of my favorite co-workers, a manager who serves as den mother for the younger staff, saw us conversing in a manner other than our accustomed jocularity and noted that we seemed concerned. We recounted our conversation, knowing that she was completely trustworthy. The gauntlet had been thrown down, how do we protect our vulnerable immigrant friend? I told her that I could drive her to work on Saturday and Sunday mornings so she can avoid public transportation, and we both pledged to her that she could contact us if ever she had a problem. She's smart, so she downloaded an app which provides advice in case she is stopped. My co-worker and I told her we'd help her to dress in a more 'American' fashion (note to self, buy New York Yankees cap ASAP) so as to look inconspicuous. When she was occupied with a task which took her away from us, we discussed educating ourselves about actions we could take if something arose.

It's particularly infuriating that this charming young woman, who should be stressing out about taking the SATs and applying to colleges, is now preoccupied with raids, with keeping her head down when she should be beaming with pride about her accomplishments. In a very big way, I am now forced to confront the question, what will you do if the unthinkable comes to pass? The topic came up at the end of the night, when the guests left, and a skeleton crew helped to rinse off and pack the dishes and glassware. We have all come to know and love someone who believes, with reason, that she could have a target on her back, how will we respond?

I remember hearing from all sorts of people back in 2016 who feared that discrimination against them would ramp up. I gave a half thought-out statement of support back then... now, I have to think about concrete means of support. What do I do should the unthinkable come to pass?

Secret Science Club Post-Lecture Recap: This Subject's Deep

On Tuesday night, I headed down to the beautiful Bell House, in the Gowanus section of Brooklyn, for this month's Secret Science Club lecture, featuring Dr Vicki Ferrini of Columbia University’s Lamont-Doherty Earth Observatory and the Center for Coastal and Ocean Mapping. Dr Ferrini's topic was Mapping the Ocean Floor, and she kicked off the lecture by noting that maps are a common part of our lives- we are a geospatially oriented culture, to the extent that we have maps on our phones, and a lot of data at our fingertips.

Most of the planet's surface, approximately 70%, is covered with water. Most of the ocean floor is unseen, unmapped, unknown. While humans have mapped 100% of the surfaces of the moon and Mars, only 15% of the ocean floor has now been mapped within a 100 meter resolution. Dr Ferrini displayed a map of the North Atlantic Ocean floor, and noted that little is known, most of our knowledge being limited to the continental shelf.

Dr Ferrini's specialty is bathymetry, the mapping of the depths. She noted that the shape of the seafloor in a very localized area can be observed at the beach. For mapping the seafloor in deeper waters, sound is used. She gave us an overview of mapping conventions, pointing out the rainbow colors of the maps, with warm colors indicating shallows and cooler colors indicating depths:

She then displayed a picture of the open ocean and joked that, on a good day, the view from her office is good, then contrasted that with a picture of a tempest-tossed sea and quipped that a bad day at work is dangerous. On a really good day, she is able to explore the depths of the ocean in the Alvin submersible, which can accommodate one pilot and 2 scientists- the Alvin is a national research asset, the use of which is open to any university faculty who gain approval. Dr Ferrini travels around the world observing the different processes that shape the seafloor, using a sound-based data acquisition system. Building a global ocean map can be likened to solving a puzzle, a coherent image of the sea floor must be pieced together. Different instruments have different resolutions, resulting in different errors- most of what we know about the ocean depths is estimated- much of bathymetry is predictive. Satellites can measure perturbations and produce a global image, but one with poor spatial resolution and low vertical accuracy. Dr Ferrini contrasted a Google maps image of Manhattan around the UN with an image of the McDonnell Seamount near Wake Atoll. In terms of resolution, satellite cannot compete with sonar. Dr Ferrini displayed a video of Alvin exploring the seafloor, and indicated that it is very expensive to map the depths.

Why do we map the oceans? Nautical charts are important for safe navigation. Maps are crucial for oil and gas exploration. Communications cables are often laid on the seafloor. Maps can also help researchers determine the progress of climate change. In one dramatic case, the search for the wreckage of the lost Malaysian Airlines Flight 370 jetliner was hampered by poor maps- one can't zoom in on an area for which no data have been compiled.

Four hundred and thirty thousand square kilometers of the ocean floor have been mapped, and the data is publicly available. Most bathymetry takes the form of ship-based mapping. Historically, this was done with a deadline, a weight on a chain which was lowered into the water, a technique which Dr Ferrini humorously characterized as 'low res/little detail'. In the 1950s and 60s, the use of sound to map the depths came into use- typically, one sonar device pointed straight down would measure directly underneath a boat to make a profile. One of the pioneers of sonar-based bathymetry was Marie Tharp, who was not allowed to go to sea until 1968, but who compiled sonar images into a map of the ocean floor in collaboration with Bruce Heezen. Their map of the mid-Atlantic ridge is remarkably accurate:

Marie Tharp's work was instrumental in the verification of the theory of continental drift. In a retrospective, she described her career:

The whole world was spread out before me (or at least, the 70 percent of it covered by oceans).I had a blank canvas to fill with extraordinary possibilities, a fascinating jigsaw puzzle to piece together: mapping the world’s vast hidden seafloor. It was a once-in-a-lifetime—a once-in-the-history-of-the-world—opportunity for anyone, but especially for a woman in the 1940s. The nature of the times, the state of the science, and events large and small, logical and illogical, combined to make it all happen.

Modern seafloor mapping uses a multibeam sonar array, a 'fan' of sound beams which create many data points when they are picked up by transducers on the bottom of the boat's hull. Dr Ferrini compared this multibeam mapping to 'mowing the lawn', complete coverage of the boat's vicinity is obtained. The multibeam array not only measures the depth of the ocean floor, but the intensity of the returning sound beams allows researchers to determine if the ocean floor is rocky or muddy. Also, anomalies can indicate the bubbles produced by methane seeps.

Continuous surface detail is obtained with these sonar arrays. Sound velocity depends of water temperature, so the data has to be corrected for. Because the ships are moving, the data has to be corrected (Dr Ferrini joked that she gets motion sickness). Many pieces of data are brought together and cleaned up. It's a slow process, a single ship would take one hundred thousand years to finish mapping the depths. One way to speed up the mapping process would be autonomous mapping platforms, a combination of surface and underwater robots... one of her colleagues developed an unmanned surface vessel which is a 'mothership' for underwater drones.

Dr Ferrini then shifted to the topic of the interdisciplinary approach that will take researchers beyond bathymetry... ship-based mapping is the beginning, and the maps can guide other research. Near-bottom mapping has been done with resolutions up to twenty-five centimeters. Dr Ferrini displayed pictures of spiky hydrothermal vents, which form the mineral-rich base of the deep-sea food web. She posed the question, what would it be like to stand on the sea floor and look around? A sense of scale has to be developed. There are emerging visualization techniques which assist researchers- Dr Ferrini displayed an image of the Hudson Canyon and delivered a groan-inducing pun: "How can we fathom this?" Once a base map is built, the Alvin can be taken down for a new perspective on the data. Mosaics of the photos can be color-corrected and compiled by artists into clean images of underwater features.

Dr Ferrini then told us about Earth's newest land, Hunga Tonga, born of a 2014 volcanic eruption. NASA satellite data measured the processes of erosion and redeposition which shaped the island (this data could be used as an analog for modelling how Martian land masses were formed). Dr Ferrini and her crew broke off from some planned work due to bad weather and pulled up to the island in order to conduct a sonar sweep from the depths to the shallows in order to fill in some blanks for NASA. A flat subaqueous portion helped to keep the landmass intact.

No single country can assemble the bathymetric puzzle alone. NOAA is dependent on a global community, a community not only made up of government and academic personnel, but of industry and the general public. Anyone with a sonar unit can contribute data. The United States National Archives make data available to all (Dr Ferrini did note, though, that certain information, such as the location of shipwrecks, has not been revealed in order to protect future archaeological sites). Intergovernmental organizations such as the International Hydrographic Organization also make data available. The General Bathymetric Chart of the Oceans (GEBCO) 2030 project aims to create a complete high-resolution map of the seafloor by (you guessed it) 2030 in collaboration with the Nippon Foundation.

Dr Ferrini stressed that the oceans are critical to human survival- 50% of atmospheric oxygen is produced by oceanic life. Ocean maps are critical to understanding the oceans. Technical innovations, such as improved sensors, improved data processing, and improved data sharing are needed. The world's oceans belong to all.

The lecture was followed with a Q&A session. The first question involved the effects of sonar on whales- the high frequency sound beams used for bathymetry scatter quickly, and pose little danger to cetaceans. Some anthropocene-obsessed Bastard in the audience asked her if she had observed any negative effects of human activity on seafloor communities, and Dr Ferrini answered that she hadn't yet, but that regulations to protect these habitats might be needed in the future. Manganese nodule mining might pose the biggest danger to seafloor biomes. Regarding changes to the seafloor- most changes occur in shallow areas, necessitating continuous surveying, but the depths are not as stagnant as originally thought. Concerning the location of earthquakes, sonar is insufficient, other resources are needed to pinpoint these occurrences. A question about the Alvin resulted in a funny aside- there is no privacy in the submersible, which operates from 8AM-5PM, and there is a sign advising users: PB4UGO. Dr Ferrini joked that occupants tend to bang their knees in the cramped interior, but everybody is too excited to notice. Regarding satellite data, satellites use optical techniques such as LIDAR, which are thwarted by cloudy or deep waters. A question regarding the extinction of oceanic life had Dr Ferrini stating that she is an ocean optimist- the ocean is the world's greatest museum, things die and become life for other things, and that humanity will be extinct before the oceans are depleted of life. In a hilarious tangent elicited by a question regarding the cost of sonar equipment, Dr Ferrini narrated a tale of shopping for a Boston Whaler with her wife and having the salesman giving her a lecture explaining how the sonar system worked.

Once again, the Secret Science Club delivered a fantastic lecture. Kudos to Dr Ferrini for hitting that 'secret science sweet spot', that combination of raw-information, explanation of research methods, and adventure narrative, leavened with good humor. Kudos also to Dorian and Margaret, and the staff of the beautiful Bell House on a job well done. As an added bonus, SSC co-founder Michael Crewdson was back in the ancestral homeland for his traditional Australian Winter break, accompanied by his oldest child. Welcome back!

For a quick taste of the Secret Science Club experience, here is a lecture by the good doctor about making bathymetric data available to the public.

Shaken, not Stirred

I’m deriving a lot of Schadenfreude from the outcries of MRA types over the casting of a black woman as 007 in an upcoming ‘Bond’ movie. It wasn’t too long ago that these same morons were losing their minds over the prospect of Idris Elba being cast as Bond. Well, now they are shaken, not stirred, because there are now girl cooties all over their male wish-fulfillment fantasies.

It’s been a while since I’ve seen a ‘Bond’ film- even in high school, I figured that they were kind of ridiculous. Reading Frederick Forsyth as a kid pretty much ruined James Bond for me, and the final nail in the coffin was Chuck Jones’ ridicule of the character in his autobiography, Chuck Amuck... a spy would have to be totally incompetent to blow his cover by acting conspicuously and giving out his name, code name.

I didn’t even bother with the ‘grittier’ reboot of the franchise with Daniel Craig in the title role (my choice for the role would have been MacGowan, Shane MacGowan, who actually looks like he smokes and drinks as much as Ian Fleming’s character). Why would I spend my entertainment dollars on a franchise which glorified toxic masculinity, jingoism, and the mindset which led to the Brexit disaster? If I want to experience reactionary attitudes, I can get them for free.

At any rate, the entertainment value over the freakout about Lashana Lynch being cast as 007 (in the franchise, a designation, not a name) is greater than the movie’s could ever be. I love it when the SJWs ruin things for bigoted assholes. The only thing that could possibly make this better is if the character’s name is Peg Butts.

Prime Directive

The Google tells me that today is Amazon Prime Day, when Deep Discounts can be found on the e-commerce titan’s website. Being a believer in the sort of mom and pop stores that anchor my neighborhood, I haven’t purchased anything from Amazon in years (though I have to confess that I would use it to buy something I could not obtain otherwise, should such an occasion arise).

Workers in a Minnesota Amazon distribution center walked off the job, seeking better working conditions. It’s a gutsy move in this New Gilded Era, an era of poor worker protections. When all you have to lose is a dangerous, unpleasant, low-paying job, you have nothing to lose. It’s been over two years since I’ve ordered something from the Bezos Borg, I think I can wait a good long time before buying those out-of-print books I had my eye on.

Being a fan of classic ‘Star Trek’, I was impressed by the concept of The Prime Directive. If I have a Prime Directive, it’s the classic ‘do no harm’. My Prime Directive directs me to avoid Prime Day. I support local businesses, and the job I end up saving just might be my own.
