Experimenting with a Magnetohydrodynamic Drive demo

Posted By on April 13, 2021

You can take the boy out of school, but you can’t take school (and learning) out of the VASIMR_spacecraftboy ( or older man at this point).

ExperimentMHD210411Over the weekend, I was talking to Brenda about how I’ve been following the NASA feed (tweet below) and waiting for the helicopter to take flight on Mars. The conversation lead to talking about engineering and when I was learning about Lorentz force (F = qE + qv x B) and electromagnetic fields. My semi-lecture, and her questioning my decades ago education, lead me to theorizing that we would eventually use this principle in a space engine or something referred to as a plasma propulsion engine.

LorentzforceBrenda remained a skeptic, so I headed down to the workshop on Sunday afternoon to create a prototype in order to demonstrate the "no moving parts" electromagnetic principle – it’s a fun science project: a Magnetohydrodynamic Drive. Anyway, she was moderately impressed and said, “you should have waited and worked on that with Annalyn and Ellerie” (maybe I will someday as it is a great idea if they ever need a Science Fair project?)

Music Monday: Sheryl Crow and NPR Music Tiny Desk Concerts

Posted By on April 12, 2021

TinyDeskConcertNPRLogoStumbled across a pre-COVID19 lockdown NPRMusic Tiny Desk Concert on YouTube when watching another video from an automotive friend of mine … and since I like Sheryl Crow “music” … I figured it would be an easy fill for Music Monday.

Her “Soak Up The Sun” hit from 2002 was included a couple years ago, but the intimate “tiny desk” concert video below is also enjoyable. We may not all like her political activism, but who doesn’t like her music?

Celebrities Then and Now Photos (popular on social media)

Posted By on April 11, 2021

Last week my sister-in-law shared an update on her Facebook page of some well-known Hollywood celebrities that I thought would be interesting to at to MyDesultoryBlog. I downloaded the 30+ different-sized photos, resized a few and decided it might work as an automated slide show (if you want my resized originals, download this .zip archive).

Celebrities Then and Now 2021

After looking at the celeb photos from “then and now” and remembering most of these actors from their younger days as well as today, it is not surprising to reflect on how many years have passed. Yup, you are reading my mind –  these celebrities aren’t the only ones getting older (photo/post when dating Brenda at ONU in 1981). 

Canary cam selfies, Taylor and his fraternity friends in the Bahamas and the passing of the UK’s Prince Phillip

It is that time of year again … spring, when the camera loving birds (1, 2, 3) sit and look at the Pool Garage camera. The downside is that every time they sit and look at the Canary cam, it triggers a motion alert to my phone.

Taylor and Megan are on their way back from a week in the Bahamas with his fraternity brothers .. they did the same in 2019. I have not talk directly with them, but from the photos (archiving), they look to have had a great time at Will’s family’s place on Harbour Island. They have remained good friends and have taken a few trips together, although few as memorable as hiking the Na Pali Coast in Kauai, Hawaii.

The news on Friday afternoon was that the UK’s Prince Phillip, Duke of Edinburgh passed away at age 99. He had been hospitalized since February and underwent surgery for a heart condition. He has been married to Queen Elizabeth II for 73 years.

Tech Friday: Innovative hearing technology on my wish list

Posted By on April 9, 2021

startrektransporterSometimes when my mind wanders, I shift from pie-in-the-sky dreaming (flying cars, mind control devices, AI/robotics (mp4), time machines (mp4), “beam me up” transporters, etc) to something that’s a bit more realistic to the world of everyday technology. Let’s get the above “pie-in-the-sky” idiom out of the way first.

“Pie In The Sky” Origin

This phrase was coined by the Swedish-American activist, Joe Hill in 1911 when criticizing the Salvation Army’s philosophy especially their concentration on saving the souls of the hungry rather than feeding them. He used it in one of his songs while leading a radical labour organization.

The expression was later taken up during the Second World War as it was used to describe elusive happiness in the face of so much death. A Californian newspaper in its November 1939 issue described Washington’s promise to the public about eating solely from war orders as “eating pie from the sky.” Over the years, it has evolved to include the way modern-day pastors treat their followers by teaching them that their reward would be in heaven and long-suffering on earth would pay off soon.  (Source: theidioms.com)

One of most people’s favorite tech gadgets is of course the smartphone …  or the Apple iPhone and iPad in my case after years with a now defunct PalmOS device (my first iPhone was in 2012). For hard-of-hearing me to use these iOS gadgets effectively though requires a bluetooth headset like the bone-conducting Aftershokz (or for some people headphones, earbuds or airpods).

AftershokzAeropex2021

The Aftershokz’s latest smaller version is the Aeropex model, but on my wish-list would be a headset that also processes surrounding sound and provide a digital hearing aid function too. While I’m building the wish-list, let’s connect the bluetooth radio to multiple devices “at the same time” so I can use it not only with my iPhone, but iPad, notebook, desktop computer, smartwatch and virtual assistant like Amazon’s Alexa.  I doubt this is too far off since I can already “tap” to connect to a second device. The advancement in cochlear implants, implantable middle ear devices and bone anchored hearing aids has also improved a lot in recent years which can make for a night and day difference for those who are hearing impaired.

Books: Reading the updated investing classic "A Random Walk Down Wall Street" by Burton G. Malkiel

Posted By on April 7, 2021

Book_RandomWalkDownWallStreet210402In keeping with a New Year’s resolution from “years ago” to read more non-fiction books and some classic literature still sitting unread on our new bookshelves, I’ve picked up a new edition of an “older” book.

Bookshelves210402

For April and more likely May (statistically good months for stock market investing), I’m reading “A Random Walk burtonmalkielDown Wall Street” by Burton G. Malkiel. The business, or more precisely, investing book was originally published in 1973, but it has been updated 12 times, the last revision in 2020 and should a little more current and up-to-date.

Some of these older value investing oriented books are timeless and have patterns and habits by excellent teachers, successful business leaders and investors that have stood the test of time. One of my favorites is The Little Book series mentioned before when reading The Little Book of Value Investing by Christopher H. Browne. I’m hoping this will be another?

Political corporate activism in Georgia, boycotts and investing

Posted By on April 6, 2021

Democrats have been gaining ground over the past few years with their “hate Trump” blitzing supported by the leftists, big tech and mainstream media (one in the same from what I’ve seen), and continue to put heavy pressure politicians and corporations. Just as with the tactics used by BLM, Antifa and “woke” groups using racism, gender, income inequality, capitialism, etc .. the latest is an attack on Georgia’s election legislation. Politicians in Georgia are attempting to prevent chaos and fraud in their elections, not suppress voting (IMHO, November 2020 was a mess). There is a media blitz and Democrat lead propaganda painting this new law as if it were Jim Crow 2.0.

GA_NY_VotingLaw210403

So what does the Georgia law do? First, it gets rid of signature matching, so election workers aren’t trying to verify mail ballots by comparing John Hancocks. This subjective process should concern both sides. It creates avenues for contested outcomes, with fighting over ambiguous signatures.

..

Instead of signature matching, voters will submit a state ID number with their mail ballots or applications. This way there’s no arguing over handwriting: The ID number either matches or it doesn’t. Georgians who vote in person are already asked to show identification. Anyone who lacks an ID can get one for free.

As the Georgia voting legislation was being hash out, opinions from corporate leaders and the community were debated … and for the most part understood and supported, but under pressure from the political activists on the left, these same corporations are “waking” or should we say becoming “woke.”  The activists have gone after corporate heads and corporations, along with sporting events such as the Masters, Major League Baseball … and their media pressured propaganda campaign and rhetoric is gaining traction once again.

atlanta2021-all-star-gameRecently each corporation has placated the left as they did for BLM and has decided to oppose the sensible voting measures that are supported, at last polling I’ve seen, by 80% of Americans ( that of Voter ID – you are who you say you are). Perhaps the most notable example of caving to the pressure of the activists mob is MLB moving the All-Star Game out of Atlanta this summer – shocking. Other companies seem to be verbalizing in a way to appease the left, but are offending others … both moderate and conservatives who approve of measures so as not to have a shady election situation as in 2020. Personally the only realistic reasons not to have voters show an ID when voting is that Democrats think they benefit from fraud (non-resident voting, illegals voting, multiple votes, voting for someone else, recount tracking, etc). Preventing and cleaning up election fraud is not some kind of voter suppression.

As much as it pains me to miss out on Major League Baseball this year  or boycotting companies .. I won’t be watching or going to a Reds games and will be choosing other products when possible … I’m not sure what SellingKOonPolitics210405else Americans can do to demonstrate our frustration with companies going political or caving to the leftist mob?

I’ve always been an advocate for Coca-Cola Company ($KO stock) and thought of it as an all-American company and as a solid investment to hold in a retirement portfolio … but not when we don’t see eye to eye anymore. There are plenty of other good companies to invest in.

Happy Easter 2021 – He is risen. He is risen indeed.

Posted By on April 4, 2021

EasterCrossFor Christians, there’s no more celebrated day than Easter … for without a risen Savior, no other day in Christianity would matter. He is risen indeed! 

BUT … why does the day always change? I mean, we’ve assigned December 25th to celebrate Christmas and most other holidays on our calendar at least fall in the same month? So why does Easter have to move around so much? Like a birthday, etc … there must have been “one” day on the calendar that Christ rose … although it was a Sunday. Hmm?

Easter always falls on the first Sunday after the Paschal Full Moon.

A look at some Jewish and Christian history helps to shine a “little” more light on the subject, but reading a BBC magazine article makes one realize just how politically charged and difficult it was for churches, let alone governments and countries, to come to an agreement on when to celebrate Easter … even if they were all using our relatively modern (1582) Gregorian calendar. It’s no wonder they couldn’t come up with one fixed date.

I’m sure that I’m not the only one who still struggles with the March through April wide span of daysthe earliest being March 22nd and the latest being April 25th. That is quite the spread … but why?

It has to do with the moon

The moon’s cycles played an important role in ancient times, which is how the date of the Jewish holiday of Passover was determined. Eventually, Christians decided to observe Easter during the same time as Passover, with early celebrations occurring on the first Sunday after the first full moon of spring.

The Paschal Full Moon and Easter

The date of Eastera moveable holiday—coincides with the Paschal Full Moon. However, the Paschal Full Moon may not be the exact same date as the actual astronomical full moon. The date can vary as much as two days from that of the actual full moon, although the two intersect more often than not.
