Masks Are For Cowards!

The Country’s Full of Sissies!

It really blows my mind that people think wearing a mask in order to protect others, as well as yourself, is somehow an indication of weakness. Is it weak for soldiers to wear helmets or gas masks when necessary? Do we make fun of Law Enforcement Officers who wear bullet-proof vests? How about nurses wearing masks, gowns, and face shields?

I guess only sheep and cowards use seat belts when driving and, really, who cares when food has reached its expiration date? It’s only a number, right?

Have I ever mentioned my belief Trump supporters are some of the dumbest idiots to ever “walk” this planet? For them, everything is politicized and science has no place in their understanding of how the world works. I’d pity them, but it seems they’re bound and determined to drag us down with them. Let’s not comply. Wear your mask in public. Let’s mitigate and bring this beast under control, which we may have to do without the assistance or coordination we might ordinarily expect from the Feds, seeing as how we have an incompetent boob at the top.


Time Stamp!

The RS-25, aka Space Shuttle Main Engine (SSME)

Just thought I should mention today (Thursday, 14 May 2020) is the 10th anniversary of my retirement from Pratt & Whitney Rocketdyne. I’m still not entirely sure it was the right thing to do (accept the early severance package they offered everyone over 60) but her I yam!


Wear Your Fucking Mask!

The Headgear Might Not Be, But The Use Of Facemasks Is Serious Business

It’s still kind of mind-blowing to me how many people don’t seem to understand the argument for wearing a mask while we’re struggling to contain this virus pandemic. While it’s true the CDC and others have changed their recommendation over time, this is not something new. Because the Corona Virus is so new (hence the name “novel”) there’s very little we can say about it with any certainty.

For instance, it’s still unknown if exposure, infection, and survival confers any kind of immunity from another, subsequent infection. If it doesn’t, then antibody testing isn’t going to tell us much of anything useful. We’re just discovering that it affects children more than we had previously thought, and we’ve also discovered the virus affects far more than merely the pulmonary system.

While it seems to me it was always a good idea to wear a mask in public once this thing had spread far enough to make containment impossible, I can understand why—when there is a shortage of masks available for our front-line healthcare workers—the authorities would suggest we not wear masks, at least not the kind that are used in medical settings. That makes sense given how important those workers are, and how important it’s been to not overwhelm our healthcare system.

Now that we know more about how it spreads, I think there are a lot of people who don’t appreciate the concept of droplets and aerosols. I have an experience that I always wondered whether or not I would be able to share without sounding a bit daffy. I think it’s apropos now, however.

I believe it was in 2015, when I had returned as a contractor to the place I had retired from five years prior. I had to drive east to get there and west to return home. I distinctly remember coming home one evening, driving into the sunset. I had a Plantronics wireless earpiece, so I could talk on my phone while driving. As I was talking normally, I could see dozens and dozens of small droplets spraying out of my mouth with the enunciation of certain sounds. It was a bit disconcerting as I’d never noticed just how sloppy we are when we’re just speaking, let alone coughing or sneezing.

How COVID-19 Is Transmitted Through Aerosol Particles

Bottom line is this; as long as we don’t have a vaccine, nor a known, useful treatment for Covid-19, the disease caused by the Corona Virus SARS-CoV-2, we need to take steps to mitigate its spread. Not necessarily to keep everyone from being exposed, but (at the very least) to spread out (flatten the curve) it’s path of infection to prevent such rampant disease that we are incapable of handling it and thousands die because we just don’t have the necessary medical infrastructure, tools, supplies, and equipment to keep our healthcare workers safe.

I know some think wearing a mask makes them look like a dork but, in my less than humble opinion, if you’re too self-centered to realize wearing one is in everyone’s best interests because it goes a long way to preventing you from spreading the virus, in case you’re infected yet asymptomatic, then you actually are a dork . . . or something much worse.

If interested, and you want to learn more about how this deadly virus spreads, here’s a great article ‘splaining it for you.


Contemporary American History

I just came across one of the better summarizations of two disparate responses to infectious diseases by our two latest Presidents here in the United States. I am not the author of what follows, but I would like to post it here, as I believe it will ultimately get more exposure than it will on Facebook (where I encountered it.)


For those of you complaining about Trump being blamed for the COVID-19 pandemic, here’s a little history lesson for everyone on both sides of the political divide. It’s important that we understand the truth, especially come November when it’s time to vote. Forgive the length, but hey, we all have time on our hands to read, correct?

In December 2013, an 18-month-old boy in Guinea was bitten by a bat and died a brutal death a day later. After that, there were five more fatal cases. When Ebola spread out of the Guinea borders into neighboring Liberia and Sierra Leone in July 2014, President Obama activated the Emergency Operations Center at the Centers for Disease Control in Atlanta. The CDC immediately deployed CDC personnel to West Africa to coordinate a response that included vector tracing, testing, education, logistics, and communication.

Altogether, the CDC, under President Obama, trained 24,655 medical workers in West Africa, educating them on how to prevent and control the disease before a single case left Africa or reached the U.S. Working with the U.N. and the World Health Organization President Obama ordered the re-routing of travelers heading to the U.S. through certain specific airports equipped to handle mass testing. Back home in America, more than 6,500 people were trained through mock outbreaks and practice scenarios. That was done before a single case hit America.

Three months after President Obama activated this unprecedented response, on September 30, 2014, we detected our first case in the U.S.A. A man had traveled from West Africa to Dallas and somehow slipped through the testing protocol. He was immediately detected and isolated. He died a week later. Two nurses who tended to him contracted Ebola but later recovered. All the protocols had worked. It was contained. The Ebola epidemic could have easily become a pandemic, but thanks to the actions of our government under President Obama, it never did. Those THREE EBOLA CONFIRMED CASES were the ONLY cases of Ebola in the U.S.A. because Obama did what needed to be done THREE MONTHS PRIOR TO THE FIRST CASE.

Ebola is even more contagious than COVID-19. Had Obama not acted swiftly, millions of Americans would have died horrible, painful, deaths like something out of a horror movie (if you’ve never seen how Ebola kills, it’s horrific). It is ironic because since President Obama acted decisively we forget about his actions since the disease never reached our shores.

Now the story of COVID-19 and Trump’s response that we know about thus far:
Before anyone even knew about the disease (even in China) Trump disbanded the pandemic response team that Obama had put in place. He cut funding to the CDC, and he cut our contribution to the World Health Organization (WHO). Trump fired Rear Admiral Timothy Ziemer, the person on the National Security Council in charge of stopping the spread of infectious diseases before they reach our country – a position created by the Obama administration.

When the outbreak started in China, Trump assumed it was China’s problem and sent no research, supplies or help of any kind. We were in a trade war, why should he help them? In January he received a briefing from our intelligence organizations that the outbreak was much worse than China was admitting and that it would definitely hit our country if something wasn’t done to prevent it. He ignored the report, not trusting our own intelligence.

When the disease spread to Europe, the World Health Organization offered a plethora of tests to the United States. Trump turned them down, saying private companies here would make the tests “better” if we needed them. However, he never ordered U.S. companies to make tests and they had no profit motive to do so on their own.According to scientists at Yale and several public university medical schools, when they asked for permission to start working on our own testing protocol and potential treatments or vaccines, they were denied by Trump’s FDA.

When Trump knew about the first case in the United States he did nothing. It was just one case and the patient was isolated. When doctors and scientists started screaming in the media that this was a mistake, Trump claimed it was a “liberal hoax” conjured up to try to make him “look bad after impeachment failed.”

The next time Trump spoke of COVID-19, we had SIXTY-FOUR CONFIRMED CASES but Trump went before microphones and told the American public that we only had FIFTEEN cases “and pretty soon that number will be close to zero.” All while the disease was spreading, he took no action to get more tests. What Trump did was to stop flights from China from coming here. This was too late and accomplished nothing according to scientists and doctors. By then the disease was worldwide and was already spreading exponentially in the U.S. by Americans, not Chinese people as Trump would like you to believe.

As of the moment I am posting this, the morning of April 20, 2020, we have 770,076 COVID-19 CONFIRMED CASES and 40,316 COVID-19 DEATHS in the U.S.A. The actual number is undoubtedly more than triple that amount.

As if you needed one more reason to vote, here it is.


Quick Covid-19 Update

Looking back on the news, it appears Governor Newsom ordered a statewide shelter-in-place on the 19th of this month (03/19/20.) However, when I look at my calendar, I see we started doing it the previous day. So, despite what I said in an earlier post, today seems to be the 10th day of our hermitage.

I’ve been spending a fair amount of time tracking the course of this pandemic, especially here in the U.S. and my home state of California. In doing so, I created a meme showing how things are changing . . . actually, accelerating with time, just as we were told would happen. Here’s that meme, which I just updated as of a few minutes ago.

I’ve also been keeping track of the growing death rate and graphing it for myself. All the data I’m using is coming from a site called worldometer and there are numerous tables and charts available there for a breakdown of all the states, as well as a list of every country’s numbers for this virus. The link I’ve provided is to the page with U.S. info on the Corona virus. If you go to their home page, you’ll find links to all kinds of statistics. Check it out.

It’s worthy to note that the percentage of deaths to total cases is 0.0154, which is considerably higher than the rate for the flu. It’s really far too early to tell if that’s what the actual death rate is, as there are just too many unresolved cases. Based on the data available now, the percentage of deaths to total resolved cases is 0.385, which is astoundingly high. What we should glean from this, IMO, is that it’s just far too early in the trajectory of this disease to gather much useful information on lethality or recovery.

I don’t know if or when I’ll update this again. It’s fascinating, but also quite depressing. Perhaps I should just watch television. 😦


Are We Alone?

“Is it all just for us, or do we get to share it with anyone?”

~ Paul Sutter (Astrophysicist on “How The Universe Works”)


Our galaxy, the Milky Way, is around 100,000 light years in diameter. That’s roughly 587,900,000,000,000,000 miles or 946,100,000,000,000,000 kilometers across. Those are in the quadrillions, which translates loosely into a “shitload.” The fastest man-made object—according to my research on the Intertubes—was a bit of a toss-up between NASA’s Helios 2 and their Juno spacecraft; that is until the Parker Solar Probe was launched. When it reaches its closest to the sun (in a few years) it will be traveling at approximately 430,000 MPH! That’s screaming. However, even at that speed it would take nearly 1,560 years to cross the entire galaxy.

Current estimates suggest there may be as many as 200,000,000,000 galaxies in the universe. Astronomers, astrophysicists, and cosmologists suggest our galaxy alone contains up to 200,000,000,000 stars. That’s an awful lot of stuff, eh?

Yet, in all of this, we have not been able to answer the most fundamental question we have about the universe . . . Are we alone? Is there life out there we just haven’t discovered? I like how astrophysicist Paul Sutter looks at it (see the quote from him, above, that I started this post off with.) I find it difficult to believe, now that we understand much of the physics and chemistry of the Universe, that life hasn’t (or won’t) evolve in places other than this one nondescript star system we call home.

Another quote I love is one I’m going to paraphrase, as the original quote, from Edward Robert Harrison, doesn’t quite provide the essence of what I’m trying to get across. His quote is: “Hydrogen is a light, odorless gas, which, given enough time, turns into people.” It almost says it all, but I think “Hydrogen is a light, odorless gas which, given enough time, begins to wonder where it came from . . . and where it’s going,” is a bit more on point.

If you are unfamiliar with, or new to, the field of cosmology you might not know what this means. Essentially, it’s refining what is the generally accepted understanding of how the Universe has evolved from nothing but sub-atomic particles to Hydrogen and, through the process of star formation (and spectacular stellar deaths via supernovae) the heavier elements have been formed . . . many of which are the building blocks of life, and us. We’re the descendants of the primal Hydrogen that made up the early universe and its first generation of stars.

To me, the concept of evolution—both of the universe itself and of life on Earth (perhaps elsewhere)—is far more incredible and truly beautiful than any origin story of any religion I’ve encountered . . . and I’ve encountered a fair number of them. Imagining the evolutionary process, which has played out over billions and billions (h/t Carl Sagan) of years is—for me—a challenging flight of fancy and an enlightening exercise in the dialectic, or zen, or yin-yang of life in this universe.

I hope one day we’ll find out we’re not alone. Perhaps that will give us the humility we need to get along with one another on this little blue dot we call home.


RAIDI

Robot and Human hands touching

I have no doubt I am a very lucky person. Although I do not have an education in any science, I was able to spend approximately two decades working on the Space Shuttle Main Engine (SSME) program at Rocketdyne (through four major aerospace corporations). I spent a lot of time working with some of the brightest rocket scientists (for realz) as well as world-class engineers and scientists in literally dozens of disciplines.

Since my retirement from (what was then) Pratt & Whitney Rocketdyne, I have worked intermittently with Quantellia, LLC, an artificial intelligence / machine learning software development firm. Needles to say, I have no formal education in any computer field, with the exception of two Visual Basic classes I took at a nearby Junior College. I was introduced to one of the co-founders of Quantellia shortly after my retirement. She showed me a tool they had been developing called “World Modeler”. It was the most exciting thing I’d seen in a long time, and I was especially impressed with how it brought a highly systemic approach to modeling and forecasting in complex situations. I ended up writing several papers and a bunch of case studies for them.

In 2015 I returned to work at what was then Aerojet Rocketdyne (still is, for now) where I worked on a small rocket engine program for a little over two years. After leaving, I started doing some selling for Quantellia and, beginning in March of 2018, I became the company’s Business Manager, a position I’m still working at.

Last year we held a summit, in conjunction with SAP Global Services, at their Labs in Palo Alto. It was called the “Responsible AI/DI Summit.” In this context AI stands for “Artificial Intelligence” and DI stands for “Decision Intelligence.” One of the main purposes of the summit was to discuss how we can develop artificial and decision intelligence such that we concentrate on using them to solve humanity’s most “wicked” problems, rather than merely work at developing apps, the main purpose of which is to make money for the developers, investors, and entrepreneurs involved in the business.

Below are some of the folks who worked on the Summit, including me (the long-haired guy in the middle of the back row). Also, here’s a link to this year’s second Summit – Responsible AI/DI Summit 2019, as well as a link to the RAIDI Blog.

Quantellia and SAP folks who worked on putting it all together

As I learn more about machine learning, artificial intelligence, and decision intelligence, I will work at sharing my knowledge and understanding of these tools, and the issues they raise. I know the people I’m working with are dedicated to serving humanity, not merely milking it for profit. That pleases me and I hope we’ll be able to prove we’re doing the right things to ensure such service continues to exist and grow.


How Ironic!

In the past couple of days there have been at least two major temblors in the Searles Valley – Ridgecrest area of Southern California, which is about 125 miles north northeast from where I live, as the crow flies. Since the shock waves created by an earthquake don’t need to drive on the highways, that’s about how far away the epicenter is. What we felt this far away was reasonably gentle though; a rolling sensation not unlike being in a boat in gentle swells. However, as anyone who’s lived through a big earthquake will tell you, any movement of the ground gets your attention right quick.

I have lately been going through boxes and files of paperwork and publications from my years of employment or when I was in business with my family or otherwise, finding things I created or encountered, which I’m sharing on my blog. I came across this today and, after doing a search for earthquakes that might have caused someone to share this, I can’t pin down which it might have been. Nevertheless, I find it ironic I would encounter this today, so soon after these major quakes. At least nobody was killed, or no deaths have yet to be reported.

And, as long as I’m here I should point out that people who know are warning that quakes are followed by an increase in cases of Valley Fever. This is no doubt due to the dust that a quake shakes loose and into the air. Here are some photos from the area that were shared by a Facebook page dedicated to dealing with the disease. Check them out for more info.


When Do We Fight Back?

At what point do we switch from nonviolent protest to righteous self-defense? Climate denial is empowering polluters who don’t give a shit how sick we get or how many of us suffer untimely deaths because of their fucking intransigence. When do we rise up in indignation and demand, or force, the changes necessary to halt climate change . . . assuming it isn’t already too late?

Random Memorabilia

I found this piece of historical info about the—shall we call it “first half”—of the Shuttle program in one of my collections of “stuff.” Note that it ends with the Challenger disaster, which happened almost a year to the day before I was hired in (initially as a temp) at Rockwell International’s Rocketdyne division, working on the document that would prepare the SSME (Space Shuttle Main Engine) for the return to flight on September 29, 1988. Note also, as engineers are wont to do, the word “Incident” is misspelled at the bottom of the sheet. Color me unsurprised. OV-105 (Orbiter Endeavour) is also not on the list at the very bottom of the page.

I don’t imagine this will be terribly interesting to anyone who isn’t a bit of a human space flight geek like me but, as I have said recently, I need to memorialize some of the things I’ve kept over the years. They may not be of value to anyone but me—hell . . . they may not even be of value to me—but I want to get them scanned or reproduced and put out into the aether, for my sanity and possible future use.
