The Trouble With Bernie




“The State is the great fiction through which everybody endeavors to live at the expense of everybody else.”
Frédéric Bastiat, 1801-1850


Socialism has become de rigueur once again, accounting for the popularity of politicians such as Bernie Sanders and Alexandria Ocasio-Cortez.

Several recent polls have shown young people, most particularly, open to socialist ideas. As summarized by CNBC, “According to a new poll from Gallup, young Americans are souring on capitalism. Less than half, 45 percent, view capitalism positively.”

This should come as no surprise. Support for socialist ideas is inversely related to one’s sense of confidence. That is, as people feel less confident in their ability to negotiate the world, their attraction to socialist ideas increases. And while the economy is booming (in spite of a currently volatile stock market), we are faced with great technology-driven disruptions. Artificial intelligence and automation are already devouring routine jobs and promise to consume even more. In the not too long run, Uber drivers and over-the-road truckers will be supplanted by robots.

In light of such uncertainties, it is reasonable for young people to ask “how will I support myself?” 

While learned professors have written millions of words detailing socialist concepts, let’s try to boil it down to the bare essentials: individual effort and private property.

Imagine a slide switch which, when moved fully to the left represents complete collectivism. In this extreme, there is no such thing as private property. The state, that is the collective, owns all assets and individuals own nothing. The result of one’s labor is added to the collective pool and you have no right to any part of it individually. Food, clothing, and shelter are doled out at as the collective wills.

Now we move the switch all the way to the right. This is complete individualism and represents no collective ownership of anything. All assets are completely owned by individuals and food, clothing, and shelter are acquired only to the extent that each individual can provide for themselves.

Now, each of these extremes is highly unlikely to ever exist as long as more than one human populates the planet. In fact, the switch hovers near the middle, perhaps a bit left in Scandinavian countries and a bit right in the United States, but all productive economies in the world both respect private property rights while providing collective support. Good examples of collective efforts include military defense, roadways, and certain government programs such as welfare and social security.

Another major aspect of the slider switch is this: when moved all the way to the left (collectivism), there is no incentive for individual effort. You may work as hard as you can or as little as you like and your personal outcome is the same. When the switch is all the way to the right, your survival is completely dependent on your individual effort and success – work or die.

Looping back to the increasing allure of socialism, young people, fearing for their future, want to nudge the switch to the left. They are willing to exchange opportunity for safety, liberty for security, achievement for guarantees. This is understandable as they have not yet grown confident of their own abilities.

But unfortunately, due to human nature, socialism reduces the incentive to excel. So while all can share in the collective pot, that pot itself will tend to suffer.

A good example of this is the early travails and then triumphs of the Pilgrims, as chronicled by Nathaniel Philbrick in his book “Mayflower.”

“The fall of 1623 marked the end of Plymouth’s debilitating food shortages. For the last two planting seasons, the Pilgrims had grown crops communally – the approach first used at Jamestown and other English settlements. But as the disastrous harvest of the previous fall had shown, something drastic needed to be done.”

“In April, [William] Bradford had decided that each household should be assigned its own plot to cultivate, with the understanding that each family kept whatever it grew. The change in attitude was stunning. Families were now willing to work much harder than they had ever worked before. In previous years, the men had tended the fields while the women tended the children at home. ‘The women now went willingly into the field,’ Bradford wrote, ‘and took their little ones with them to set the corn.’ The Pilgrims had stumbled on the power of capitalism. Although the fortunes of the colony still teetered precariously in the years ahead, the inhabitants never again starved.”

A good lesson for us all.

Finally, regarding private property rights, remember that even ardent socialists lock their doors.

5G is coming. Why you should care.



Imagine a cocktail party, a loud cacophony of sound permeating the room, booming music and shrieks of laughter. You are shouting at the top of your lungs to your distant better half while she is simultaneously whispering to you. Further, imagine that you understand her perfectly.

This unlikely bit of magic is the equivalent of 5G full duplex radio, where your cellphone will be transmitting and receiving on the same exact frequency at the same exact time. Today’s cell phones can transmit and receive at the same time, but only on different frequencies. This new technique effectively doubles the amount of information (voice or data) that can be carried by an allotted frequency spectrum, one of the significant promises of 5G.

5G is the fifth generation of cellular radio technology and is currently being phased in. It promises extremely high speed, very low latency (delay), increased data capacity, and energy savings among other advantages.

There are a number of new technologies required to support 5G. You will hear of New Radio (NR), millimeter wavelength, small cells, massive MIMO, beamforming, full duplex, M2M, and other cool stuff. But keep in mind, most of these are used to support the major performance objectives of high data rate and low latency. Let’s focus on them.

High 5G data rate offers an alternative to cable

5G has an achievable performance target of one gigabit per second. A traditional wired home cable WiFi connection of 100 megabits per seconds is considered extremely fast. 5G is at least 10 times faster which offers a very real alternative to traditional cable. Recent research in Australia revealed that one in three households there were interested in subscribing to 5G services to replace cable for internet access. Especially in new service areas, cellular radio access will be much more economic than fiber cable runs.

High 5G data rate will enable new cellular applications

Current 4G cellular commonly offers 10 megabits per second download, so 5G will increase that by a factor of 100. While such a huge performance increase is not required for reading email or updating Facebook, an entire new panoply of applications will be enabled. Think virtual reality and augmented reality. But then think further, beyond a human cellphone user, and consider server-to-vehicle and vehicle-to-vehicle communications of autonomous automobiles. This is the tip of the iceberg of new applications enabled by 5G’s extreme high performance. It is almost impossible to foresee the application landscape five or ten years hence.

Low 5G latency is good for gamers. Surgery, not so much.

Data rate describes the speed of a connection once data starts to flow. Think of a NASCAR racer going 200 mph. Latency, on the other hand, measures how long it takes that data to start flowing between the sender and the receiver. Think of how long it takes that NASCAR racer to get from zero to 200 mph.

5G promises to offer very low latency of one one-thousandth of a second (one millisecond). For PC gamers, this is a boon. Gamers like to experience their virtual environments as if they were unfolding in real time. Business users, similarly, want videoconferences to unfold smoothly.

You will hear claims that 5G low latency will aid a surgeon in New York to perform robotic surgery in San Francisco. That is balderdash. The propagation of a signal in a fiber backhaul network over 3,000 miles will add a minimum of 25 milliseconds to the connection, dwarfing any advantage of low 5G latency. No, latency is subject to the laws of physics, so to be of benefit, network nodes (servers, users, routers, etc.) must be in relatively close proximity.

Is 5G real?

Yes, 5G is real and is being rolled out now. Billions of dollars are being invested in research and infrastructure. One measure of this reality is the number of 5G patents filed, which is huge and growing.

Are there impediments?

Yes, there are impediments, mostly political. The federal government recently decreed that state and local authorities cannot slow-roll the approval of 5G base stations. 5G uses very high radio frequencies and thus the area serviced by each base station is relatively small. Therefore, there will be a large number of small base stations. Political impediments would be very costly.

Will I need a new phone?

Yes, but when you next upgrade to a new phone, it will most likely support 5G. Some already do. In the meanwhile, carriers will continue to support and expand current 4G networks.

Bottom line.

5G is new, heavily marketed, and subject to much hype. But it is real, significant, and will lead to applications we can’t currently envision. Let’s all smile, relax, and enjoy the ride.

Here's an idea... Let's enforce some laws.




The most recent issue of Guns and Ammo magazine ranks Massachusetts near the top of a list of states hostile to gun owners. Only New York and New Jersey are stricter.

It is reasonable to think that non-gun-owners would celebrate the Massachusetts ranking. And that gun owners might not. While that’s true, a recent survey suggests a surprising amount of agreement between these camps.

The survey of 2,100 people, conducted by the John Hopkins Center for Gun Policy and Research and reported in the American Journal of Public Health, tested support for 24 gun policies. Here is there overall finding: “Although there are important areas where Americans disagree on guns, large majorities of both gun owners and non–gun owners strongly support measures to strengthen US gun laws.”

The authors go on to describe that areas of most common support, that is, upon which both gun-owners and non-gun-owners agree. “Policies with high public support and minimal support gaps by gun ownership status included universal background checks, greater accountability for licensed gun dealers unable to account for their inventory, higher safety training standards for concealed carry permit holders, improved reporting of records related to mental illness for background checks, gun prohibitions for persons subject to temporary domestic violence restraining orders, and gun violence restraining orders.”

This is good news for policy makers as it indicates broad common ground for minimizing firearms deaths. The authors, however, with abundant understatement, sound a cautious note: “insufficient enforcement of and compliance with these laws limit their effects.”

It is this last bit that drives honest gun owners absolutely nuts.

Politicians, as is their wont, continue to press for new, more restrictive gun laws. In Massachusetts, Attorney General Maura Healey roils gun owners by reinterpreting laws previously passed by the legislature. In Rhode Island, Governor Gina Raimondo creates new gun restrictions by dictate without legislative action. It is not a comforting environment for gun owners.

The most common complaint you will hear from these folks is this: “Instead of a new law, why don’t you just enforce the ones that we already have?”

They have a point, and here is a good example.

In March of this year, John D. Williams of Madison, Maine, was arrested in Haverhill, Mass. According to The Eagle-Tribune (North Andover), “State troopers arrested a man from Maine for having a gun without a license after they came upon his stranded vehicle on the side of Interstate 495.”

Williams was charged with the following: possession of and carrying a firearm, improper storage of a firearm, possession of ammunition without a Firearms Identification Card, possession of a large capacity feeding device, and several traffic offenses. Williams was held on $10,000 bail.

Williams appeared before Judge Michael Patten who reduced his bail to $7,500 in spite of the gun charges and a long criminal history. Williams appealed his bail to the Essex superior Court and Judge Timothy Feeley further reduced it to $5,000. Williams paid the bail and was released.

On the very day that Williams was due back in a Massachusetts court, he was accused of shooting and killing Maine Sheriff’s Deputy Eugene Cole. Corporal Cole, a US Army veteran, left a wife and four adult children.

This is not an aberration. In a case from April of this year we lost a Cape Cod police officer.  The defendant, Thomas Lantanowich, “is well-known to Cape Cod Law Enforcement as a notorious and violent criminal with 111 prior criminal charges in Massachusetts and currently out on probation with several criminal cases pending” according to the Yarmouth Police Department. 

Officer Sean Gannon, his victim, was also a victim of our porous criminal justice system.

Massachusetts judges routinely issue mere slaps on the wrist for gun violations while politicians continue to clamor for more restrictive laws. Does anyone see the disconnect here?

This is one more thing on which gun owners and non-gun-owners may find common ground: Enforce existing laws and hold criminals accountable for their actions by imposing meaningful punishments.

Here’s what you can do. Read the news. Pay attention. Hold our politicians and judiciary accountable.

Change starts with you.

Pondering life from slightly abaft



Often things seem so clear to us but we are wrong. Sometimes surprisingly so.

We gladly plop down a few bucks, occasionally many bucks, for lottery tickets and think there is a reasonable chance that we will win. But that chance is fleetingly slim, so much so as to fade into shimmering invisibility. A million to one. Ten million to one. Five hundred million to one. But a nearly sure thing, like a very long-term regular investment in a 401K retirement account, doesn’t appeal. A friend, the owner of a convenience store, relates anonymous accounts of customers who spend hundreds of dollars a month on the lottery. To them, that is their retirement plan. Hopes of hitting the big one.

We follow all sort of odd diets with mixed success and poor long-term results, because the experts’ recommendations (National Institutes of Health, Centers for Disease Control, Harvard Health, and so on) just seem so quotidian and lack the snazzy social media seal of approval. We eschew carbohydrates without discriminating between high and low-quality carbs. We overload on meat protein because the typical American serving size is big enough to feed any three people. We consume enough sugar to sink a battleship and enough alcohol to refloat it. And then we sit on our generous behinds, persist in our physical idleness, and wonder why our weight remains stubbornly high. It’s not rocket science.

We wonder how Facebook can treat us, their customers, so shabbily. And while we glory in our belief that Facebook is free, we ignore the ancient dictum that there’s no such thing as a free lunch. Which leads us eventually to the realization that we are not Facebook’s customers. We are its product, neatly catalogued and packaged and sold to advertisers and marketers and pollsters. The same is true of any “free” service such as Google or Twitter or Gmail or Instagram, to each of whom we are only a slick product.

And then there is the media, the cable and broadcast and print behemoths in which we invest our trust. The cracks begin to show when we see a live action reporter struggling against the seemingly gale-force winds of a hurricane, only to spot a couple of teenagers strolling nonchalantly by in the background. We begin to question, are there any other exaggerations or distortions? Slowly, we begin to understand that, here also, we are just a product being delivered to advertisers. And that the key objective of the media is not to inform, but to keep our eyes glued to the screen through the next commercial message. What chumps we are.

Speaking of chumps, we are barraged by a constant variety of telephone and mail and email scams. The attackers are ingenious and constantly changing and refining their approach. “This is the IRS. A recent audit has revealed that you owe $10,000 in additional taxes. If you do not pay immediately, your driver’s license will be suspended.” Or, “This is your grandson. I am in terrible trouble. Please don’t tell my parents. I need $5,000 immediately to be released from jail.”  And so on. These people are vicious sociopaths.

Is there anything we can do in defense?

You darn well betcha there is. The first thing is to become far more skeptical. Skeptical of huge payoffs. Skeptical of profit-making diet plans. Skeptical of free stuff. Skeptical of the media. Skeptical of demands for money. This doesn’t mean becoming hard-hearted, just more discerning and careful.

Next is to inform yourself. Numeracy is vital. Take an adult continuing education course in statistics and probability. And another one in finance. Become more aware of how the world works.

Widen your sources of information. Read several newspapers. Browse many websites. Watch many news channels. Expand your mind.

None of this is a guarantee. But if we all exerted a bit of extra effort, we would find ourselves more in control of our destinies, and more comfortable in our skins.

But all this aside, don’t forget to count your blessings. The beauty of an early sunrise. The joy of gamboling squirrels and chirping birds. The joy of blooming flowers.

Life is a balance. Live it empowered.

Science is in another golden age




It is a truly mind-boggling period to be alive. Every time we turn around, there is news of yet another unbelievable scientific achievement. While science has been said to have had several golden ages (as evinced by such as Da Vinci, Newton, Faraday, Curie, and Einstein), it is fair to say that we are currently in yet another one.

Here is only a small sampling of what is going on lately.

Genetic genealogy solves crimes

The analysis and understanding of human DNA has finally reached the point where old, cold cases are being busted wide open. Earlier this year, police in Washington state arrested William Earl Talbott for the 1987 murders of Jay Cook and Tanya Van Cuylenborg. And more famously, cops in California apprehended Joseph James DeAngelo as the prime suspect in the Golden State Killer murders.

Both arrests were based on a new technique called genetic genealogy, whereby the suspect’s DNA from the evidence files was used to locate his relatives using public genealogy databases. From that starting point, old fashioned police shoe leather was used to zero in on the subject. While there are some real privacy concerns to be managed, this technique promises to bring to justice a great number of heretofore unidentified serial rapists and murderers.

Robots reading your mind

MIT roboticists having been working on the man-machine interface and have made a remarkable breakthrough. Daniela Rus and her colleagues developed a system where a human controller, with electrodes worn on their head and forearm, are able to control the behavior of a robot by simply thinking their commands and flicking their wrists. This technique would be useful for able-bodied humans trying to control robots in noisy or dim environments, and also for patients with limited motor abilities, such as the recently deceased and greatly missed Stephen Hawking.

The current electrode headwear is clunky and expensive but, like all other technologies, would quickly become more sophisticated and cheaper with competition.

Fiber-optic cable seismology

In 1851, the first commercial undersea telegraph cable was laid across the English Channel from France to England. Since then, we have progressively improved the technologies involved and now there are over a million kilometers of fiber optic cables crisscrossing the world’s ocean floors.

Barbara Romanowicz of the University of California and her colleagues have proposed a method to locate under-ocean seismic activity using this network of cables. Light is injected into one end of a fiber cable and the output at the other end is analyzed. If the cable was shaken by seismic activity, the output light will be distorted. By comparing the inputs and outputs of several cables, the location and magnitude of the disturbance can be computed. Since most existing seismic stations are land-based, the technique would add a valuable dimension to the whole picture of seismic activity. This would be particularly useful in posting timely tsunami warnings.

Electronic chips in aerosol spray

If anything seems like science fiction, this is it. MIT chemical engineer Volodymyr Koman and his team have built microscopic electronic chips that can be sprayed into an environment to detect various chemicals or pollutants. Each tiny chip is light-powered and is analyzed by collecting them all up and exposing to electrodes to read out their settings. In the future, the chips may output light signals allowing them to be optically scanned. These tiny sniffers could be used to detect pollution, gas leaks, and other contaminants. Human medicine is also a possible application, with these tiny devices injected into the digestive tract or bloodstream. This is a practical application of the revolutionary field of nanotechnology.

Gut microbes relieve autism

Researchers investigating the causes of autism had theorized that digestive upsets were correlated with the condition. As a result, they suspected that relieving the digestive condition through microbiome intervention might mitigate the autism symptoms.

Rosa Krajmalnik-Brown, of Arizona State University, and her colleagues mounted a small study of 18 children with autism. They performed fecal transplants to boost the childrens’ microbiome, particularly adding the Prevotella bacteria, and found that their autism symptoms were reduced for up to two years. It’s still too soon to call this a cure, but it is certainly encouraging research.

This is just a smattering of what’s going on in the sciences. For instance, a recent experiment used CRISPR gene editing technology to cure muscular dystrophy in beagle puppies. This is enormously promising research.

There is no better time for young women and men to get into STEM studies. Science, math, biology, and physics will provide a red carpet into the enormously exciting and rewarding research of our future.

And, more importantly, you will be greatly improving the human condition. Thank you in advance, and God bless.

The Sun, Our sun, the One and Only Sun

Lick Observatory, California  

The Santa Clara Valley, a region containing “Silicon Valley,” extends down along the southwestern shore of San Francisco Bay. It includes such well-known communities as Palo Alto, Mountain View, Sunnyvale, Santa Clara, and San Jose. Before it became a mecca of computer chips and iPhones and Google and artificial intelligence, it was a prolific producer of fruits and vegetables. The extensive fields and orchards are long gone, but the Lick Observatory still overlooks it all.

On the summit of Mount Hamilton, in the Diablo Range to the south of San Francisco Bay, are seen several bright white dots. They are visible from most of the Santa Clara Valley, situated well above the rare snow line, at 4,265 feet.

These brilliant dots represent the observatory buildings of Lick, built in 1876 which became “the world’s first permanently occupied mountaintop observatory.” (Wikipedia) 

The observatory is still very much active and is managed by the University of California (Santa Cruz). It is accessed from US Route 101, exiting to Alum Rock Road in San Jose and climbing steeply into the mountains to the southeast. The white domes seem quite close as you climb, but you would be shocked to know that you still have ten miles of excruciating switchbacks to reach them. A beautiful drive, and once one reaches the summit, many treats await. On a clear day, the entire San Francisco Bay, and even San Francisco 60 miles to the north, are visible. The entirety of the Santa Clara Valley is revealed. And the Bald Dome of Yosemite reveals itself to the east, across the broad Central Valley. To the culinary-minded visitor, it is wonderful to snatch a handful of wild California Bay Laurel leaves to power up some dish at home.

The Lick Observatory has been used for a wide range of astronomical studies, and is still used for sun studies. Especially during eclipses, when we can see the solar prominence (extremely hot gases extending outward from the sun). This is important because we are still trying to understand why the sun’s outer atmosphere is hotter than the surface. And this understanding is imperative, because the sun is the energy source that powers all life on earth. If you don’t care about this, you are simply being mulish.

There is a great deal of solar research going on and our understanding is increasing. Dr. Emily Mason of the Catholic University of America has been studying the blobs of plasma which fall like rain on the surface of the sun. She found that, while the temperatures differ wildly, the physics of the phenomena are identical to how rain is produced on Earth. Amazing stuff.

And finally, the Parker Solar Probe launched last week by NASA.

This is a spacecraft named for Dr. Eugene Parker, a physicist who first posited the existence of a solar wind. After much opposition and derisive merriment, he was proven to be right. The eponymous Parker Solar Probe, the fastest spacecraft ever at over 430,000 mph, will give us incredibly detailed information of the solar function once it reaches the sun. And the best part of this is that Dr. Eugene Parker is still alive at age 91. God bless him.

And it is remarkable how far we have come in a relatively short time. It was only 409 years ago this week that Galileo Galilei demonstrated his new invention, the telescope, to Venetian officials. Now we are hurling $1.5 billion telescopes into the heavens.

But why all these explorations, why do we care? Because the sun is our mother, our father, our god. Without it we would not survive. We must understand it.

Which is a great reason for you to visit the Lick Observatory. Bon voyage.

New England - a lot of sea to see

A Cuttyhunk quahogger returning with his catch.


Saturday last, early in the day, we were running up the bay from Jamestown to our home port in Cranston. The weather radar map was scary, splotched with angry red and yellow cells of nasty weather. (In fact, Webster Mass was clobbered by one or more tornadoes about that time).  

Everything was in our favor: following wind and waves, incoming tide. But still our modest sailboat made only six and a half knots at the very best, even with a boost from our “iron jib.”

It was a scary race but we narrowly won it, arriving at the Rhode Island Yacht Club with only a slight soaking, then remained onboard, snugly tied to the dock, for several hours as the deluge built, peaked, and eventually subsided. It was with great relief that we thus concluded our eight-day sailing sojourn in New England’s fabulous waters.

What a treasure we share, the Elizabeth Islands framing Buzzard’s Bay, quaint seaside villages such as Padanaram (in South Dartmouth), the larger islands of Martha’s Vineyard, Nantucket, and Block Island, the protected reaches of Narragansett Bay. People come from around the nation, and indeed the world, to visit our seas and islands and beaches and shores. They come for the beauty, the delicious seafood, and our interesting history.

And you don’t need your own boat to explore it. The ferry services offered in our region are numerous, and many destinations may be accessed by car. For instance, Jamestown RI (Conanicut Island) is only about a one-hour drive from the Sun Chronicle area, using either the Jamestown or Newport bridge.

But such was not always the case. Before the bridges, Jamestown was reached by ferry. As a matter of fact, the curiously wide, ruler-straight, mile-long Narragansett Avenue bisecting the island, linking East Ferry and West Ferry, was purpose-built as part of that system. According to a local history, “By the late 17th century, East Ferry, West Ferry, and their connecting cross-island road were an important link between Narragansett Country and Newport and beyond.” For several hundred years before the bridges appeared, agricultural and manufactured goods, as well as travelers, flowed across Jamestown from the mainland to Newport and vice versa. To those who are tickled by history, this is great stuff.

Cuttyhunk Island, at the western end of the Elizabeth chain, is a jewel. It can be reached by ferry from New Bedford and is well worth the trip. After climbing Lookout Hill (from which World War II watchers looked for German submarines), one can see the mainland, Gay Head on Martha’s Vineyard, and the Elizabeth chain stretching to the northeast. Bring plenty of cash. None of the business we encountered accepted credit cards, and there is not an ATM to be had on the island. But there are fifty-two year-round residents, a number that expands considerably during the summer, who work hard at a variety of entrepreneurial vocations. The seafood is fresh and fabulous. The quiet is soothing. The views are immense. And if you can stay overnight (on your own boat or at one of the island’s B&Bs), the thick belt of the Milky Way on a clear night is a sight to behold.

Padanaram, a village in South Dartmouth, is a charming seaside locale easily accessed by car. There are many older homes featuring architectures of the 18th and 19th centuries. Shopping and restaurants featuring local seafood and farm-to-table produce are great attractions. The views of Apponagansett Bay from the Padanaram swing bridge are enchanting. This would make a terrific day trip.

But here is the greatest finding of our journey: hope for the future. At each and every stop, Jamestown Dutch Harbor, Cuttyhunk, Padanaram, and the home-port Rhode Island Yacht Club, we met college kids who were spending their summers as dock hands or launch operators or bartenders. They were, to a person, intelligent, motivated, and kind. They were preparing to return to their studies: chemical engineer (a young woman), optometrist (a young man), research psychologist (another young woman), and quite a few more, equally impressive. Generation Z is remarkable, and we are thankful.

Let’s close with this: Go see New England, your birthright. Don’t let the tourists enjoy it more than you do.
