My Trip to the Stars




I have been traveling quite a bit over the past few weeks. In fact, I have never been as far away before. It all started with an innocent trip through the first few chapters of a book called ‘A Short History of Nearly Everything’ by Bill Bryson. I resigned myself to spend my evenings with a 600 page popular science companion instead of watching the boob tube, but I never made it to the last stop. I got stuck in the first few chapter of the book, where the author writes about Space.

The problem with reading about a subject you know nothing about, is that there are so many hurdles. I kept stubbing my toes against a new concept in just about every other sentence. I had to take detours to visit Wikipedia, which led me to You tube, which led me to an inventor’s site and so on. As you can imagine, I got completely lost on the back roads of my trip and I didn’t even have a GPS with me. It took mother nature to help me find my way back. There was this big storm that zapped my router and I was staring at black nothingness. No, it wasn’t interstellar space, it was my computer’s black screen.

But I was hooked. As soon as I rebooted, I found myself back in Youtube land, gorging on videos about space until my head started to spin.

I knew of course that space is BIG, but on this trip I realized how incomprehensibly big it is. Even physicists have a hard time coming up with new units of measurement to describe the incredible distances out there. The measly Astronomical Unit (AU: 92,955,000 miles), or even the light year (5,878,625,400,000 miles) fall short of measuring intergalactic space. We now have the parsec (3.27 light years), the kiloparsec (1000 parsecs) and megaparsec (1 million parsecs). The center of our galaxy, for example, is about 8 kiloparsecs away, which equals 8,000 parsecs, or 26,160 light years. Adding all the required zeros to convert it to an earthly measurement, only makes it more incomprehensible.

Not only are distances mind blowingly large, but the stuff in space, the stuff we are exploring, is by far the exception rather than the rule. That is why I am in such awe of what scientists have discovered. Looking for stuff and sending a probe to observe it, is like finding a pebble in the Pacific Ocean, sending a diver into shark infested waters and expect him to faithfully come back with important information without being shredded to pieces.

Take Pluto, for instance. It took the New Horizons space probe 9 years to reach this dwarf planet, which is smaller than our moon. It is inside the Kuiper Belt, a doughnut shaped region beyond Neptune. Pluto is a mere 3.67 billion miles from the sun, which is 40 times further than the earth!



I cannot decide which is more fascinating: the images that the probe sent back, or the probe itself. It was launched in 2006 and on its way to Pluto, New Horizons was put to sleep, to save energy, but not before it did a few gymnastics tricks called ‘gravitational slingshots’. Those are ingenious maneuvers to increase a space probe’s speed. The probe gets as close to the planet as possible without being sucked in and by using a planet’s orbital speed, it catapults away from it. It shaved 3 years off of New Horizons’ travel time.

Wearing a Mask Makes us More Free



‘Why should I wear a mask?’ you might ask. Does it not infringe on my individual freedom? We live in a free country, and freedom is enshrined in the Constitution.

In a brilliant article in the Wall Street Journal entitled The True Face of Freedom Wears a Mask, professor Kwame Anthony Appiah concludes that having to wear a mask does NOT infringe on a person’s liberty. However, he comes to that conclusion after asking the more basic question: ‘what do we mean by freedom?’

According to philosopher Isaiah Berlin, there are 2 types of liberty: ‘negative liberty’ which is freedom from external restraint on one's actions, which he calls ‘ freedom from’ and ‘positive liberty’, which is having the power and resources to fulfill one's own potential. This he calls ‘freedom to’.

The seeds in my garden are a good examples of these 2 types of freedom: seeds have the potential to become wonderful plants. They need space to grow (negative liberty), but without care and food (positive liberties), they will die.

The problem with living in a free country, is that people forget how much we rely on positive freedoms to enjoy our negative freedoms. In Jack Kerouac’s famous novel ‘On the Road’, nobody stops Sal and Dean from barreling down the interstate highway. They enjoy their negative freedom. But they couldn’t have been free to do so if the Government hadn’t built the highway in the first place, giving Americans the resources to drive cross-country (positive liberty). Read more...

Super Hero or Wimp? The Staying Home Dilemma

Photo: Ed van der Elsken


Being on self-prescribed ‘lockdown’ since the pandemic began has not been very difficult for me. Why? In order of importance, I would rate my age, my life style, my expectations and my lack of social contacts.

My friend Jane, on the other hand is a social butterfly. She is only a few years younger than I, but I would qualify her as a ‘lockdown rebel’. When we first realized that there was this killer at our doorsteps, targeting the most vulnerable in the herd, Jane and I prepared ourselves for a Coronavirus long distance run. Time will tell if she is the hare and I the turtle, or vice versa.

While I am sitting at my desk, sweating profusely in the summer heat, reading New York Times articles that scare the bejesus out of me, Jane is running along the Charles River. She goes swimming across Spy Pond, flies to L.A. to see her sister and invites her many friends and neighbors over for social distancing dinners in her backyard.

I am sure Jane thinks I am a wuss. She keeps asking me over, but I always find an excuse so I won’t have to drive the 20 minutes to her house. Me, who in her younger years, hitchhiked across half of Europe, lived and worked in England, Holland and Spain, who most recently went deep sea diving in Belize and hiked in the jungle of Kauai where Jurassic Park was filmed. When did I turn into such a fraidy cat? Read more...

How to Win over an Anti-Masker



Why are some people so resistant to wearing face masks, even though there is ample scientific evidence that they prevent the Covid19 virus from spreading? It’s easy to say: ‘Well, they are misinformed. They are just plain stupid. They are selfish and not thinking of others.’ But covering your face to protect yourself from an enemy that you cannot see, smell, hear or feel is like trying to punch someone in the dark. Some of us have no problem following the recommendations of the medical experts, but to others, it seems pointless and not worth the inconvenience it creates.

The only ‘proof’ that this faceless, odorless, silent enemy exists at all, is the reported number of infected individuals and the many deaths, but even this horrible truth is not enough for some Americans.

These same Americans gladly don a gas mask when they see toxic fumes emanate from a chemical site. They don’t shout: “If God had wanted me to wear a gas mask, I would have been born with a gas mask.” They have no problem wearing a diving mask when they go deep sea diving in Belize (unless they are suicidal, of course). The welders among them do not invoke their ‘individual rights to choose’, when they are sent on a job, where highly concentrated ultraviolet and infrared rays would cost them their eyesight.

These same anti-maskers wear ski masks to prevent frost bite. Were they to visit Saudi Arabia, (which they never will, since it is Satan’s country) they would wear a Bedouin scarf to protect them from swallowing sand and coming back home the color of a cooked lobster. Their right to choose in those situations is as relevant as asking a starving person if they would rather eat now, or wait till next week.
To anti-maskers, the face mask has become the whipping boy of the Coronavirus, like the princes of yore, who had a whipping boy receive corporal punishment in their stead. They cannot tell the virus to take a hike so they refuse to wear a mask instead. Read more...

The Tree Killers



My husband and I live in a quiet part of a suburban town in Massachusetts. Many moons ago, as two young immigrants from Northern Europe, we didn’t know where the wind would blow us. We could have ended up in Iowa or Texas, but we lucked out and settled in New England.

If there is one adjective to describe this part of the country, I would vote for the word ‘green’. The further up you go, traveling through New Hampshire or Vermont towards the Canadian border, you enter The Great North Woods, also known as the Northern Forest. It is spread across four northeastern states: Maine, New Hampshire, Vermont and New York and collectively covers 26 million acres, about the size of Holland, Belgium and Denmark combined.

But here it is equally green. Our property is nothing special, a little piece of land, about an acre, including a very modest ranch house. But at this time of year, our yard is bursting with life. An amazing array of birds, gold finches, chickadees, bright red cardinals and noisy blue birds all flock to our bird feeders, patiently waiting their turn to feed.

Many little creatures share our property. Chipmunks race back and forth, their cheeks stuffed with treasures, grey squirrels chase each other for fun or love, jack rabbits munch on clover, their jaws working overtime, and we see the occasional fox or deer come by to pay us an early morning visit.

There are Norwegian maples, lilac trees and dogwoods growing out of the unusually tall grass, since we don’t believe in giving our lawn a crew cut. But what I cherish the most, are the majestic white pines that have lived here for much longer than any of us. New England is the opposite of the vast expanses of the prairies of the mid west. Here, trees are king and the king of kings is the white pine. Read more...

Is Tyranny Winning?



I recently read Timothy Snyder’s ‘On Tyranny’ (2016), a short but very rousing book. It made me realize, that I spent my entire life, which is quite long by now, under a system of government whose values I have always taken for granted. It is called Democracy.

But nothing about it should be taken for granted. Since Trump became our President, I realize how ‘unnatural’ this order really is. It is ‘unnatural’ in the sense that were it up to nature, things would be arranged quite differently.

Nature doesn’t give a fig about the ‘rule of law’, about ‘freedom’ or ‘equality’. You won’t see a gazelle stop dead in her tracks while fleeing from a cheetah and say: ‘Hey, stop right there! I have my rights too, you know!’ We made up those rules and those concepts because it made living together a lot safer, freer and ultimately more enjoyable.

I was born and fled a country that had a tyrannical regime. Hungary was part of the Communist block for almost 60 years and, even though I was a child when I left, there was enough talk in our family about the dangers of totalitarianism. I should have recognized what was happening in the US a lot sooner than I did. Besides, being a septuagenarian, I have had enough time to learn how to recognize rot when I see it. But I didn’t. Like many of us, I suffer from complacency and a sense of entitlement.

Snyder meant to write On Tyranny as a manifesto, a wakeup call for people like me, who are asleep while walking around. People who say things like ‘It will work out’, ‘It is just temporary’ and ‘This cannot happen here’. But there is nothing ‘exceptional’ about America. Even though the country was founded on democratic principles to fight tyranny, nothing prevents a tyrant from taking over that system. The only advantage America has, Snyder says in his Prologue, is that we can learn from Europe’s past mistakes. Read more...

How Speaking Can Spread the Virus



When Prime Minister Justin Trudeau was asked about the benefits of wearing face masks to stop the spread of the Coronavirus, he said that “they are helpful in that they protect others from you “breathing or speaking moistly on them.”

The word ‘moistly’ caused a universal uproar. Comedians had a field day as usual, but Trudeau was actually giving an appropriate and descriptive name to one of the major avenues of infection, which is our own speech.

One of the reasons COVID-19 spreads so quickly is that it is transmitted from people who are asymptomatic. But if they don’t sneeze or cough on you, how are they actually infecting you?

Research is now showing that coughing and sneezing are small potatoes compared to the amount of aerosols people emit while they speak. Coughing and sneezing are like brief but potent rain showers, whereas speaking is a day long drizzle, with smaller drop sizes that can penetrate deeper into the lungs of the unfortunate recipient. They also remain airborne longer, since they are smaller.

It is not just speaking that releases more particles than coughing or sneezing. A person who decides to declare their love by bursting into a serenade, is actually emitting 6 times more airborne droplets than if they were merely reciting a poem.

If things weren’t bad enough, it turns out that people with loud voices emit an inordinate amount of particles. Not only are they a danger to your ear drums but they actually are equivalent to the fire breathers of yore.

Although the louder you speak the more particles you emit, the study also found that certain units of speech generate more aerosols than others. For example, the "E" sound in "need" produces more particles than the "A" in "saw." Read more...

Science Fiction Becomes Rality




It finally happened. Armageddon has arrived. For over a century, we have been treated to various forms of science fiction. A large portion of this genre’s books and movies has always been apocalyptic - presenting one scenario or another about the end of the world, or at least the end of humanity.

I grew up devouring the works of Isaac Asimov, Ray Bradbury, Arthur C. Clarke, Philip Dick, Robert Heinlein, H.G. Wells and many others.

Wells’ The War of the Worlds came out as a radio adaptation in 1938 and as a classic film in 1953. Other classics that mesmerized me as a child include The Day the Earth Stood Still (1951) and The Invasion of the Body Snatchers (1956).

Television added a flood of Science Fiction, including Star Trek (the original series, 1965-1969, still my favorite, followed by multiple subsequent “generations”).

Meanwhile, by the end of the 20th century, Hollywood was inundating the market with mega productions of questionable quality - such films as Independence Day (1996), Mars Attacks (1996), Armageddon (1998), Deep Impact (1998) and many others.

Even I tried my hand at the genre: (See my Humanity’s Future: The Next 25,000 Years). At least, my book is not apocalyptic. It goes more along the optimistic prognoses found in many episodes of Star Trek - predicting humanity’s progress rather than downfall.

Hot Spots, Soft Spots and Bald Spots



The English language is really good at turning words into versatile tools that can be used for many purposes, like a Swiss army knife. Take the humble little word spot, for instance. With a snap of our fingers, we can make a spot become hot, sweet, tight, bald, cold, dead, soft or blind. And those are just the noun words. We can ‘be spot on’, an adjective, ‘hit the spot’, a direct object, or ‘spot something a mile off’, a verb. We have a knack for breathing life into language by dressing up simple words and send them out into the world to work their magic.

But why stop there? A single one of these ‘compound nouns’ can, itself, take on different meanings. A spot can be hot, but a hotspot can be a place of unusual popularity, a spot where volcanic magma rises through the earth’s crust, an area of political or civil unrest, a place where a wireless Internet connection is available and more recently a place where the Coronavirus is particularly active.

When I drove down dreary Route 9 in Newton the other day, I didn’t think it was unusually popular and there was no magma in sight. My phone didn’t detect a wireless connection and since I didn’t have a dog in the car, I couldn’t check for its infected skin rash.

But I knew I was entering a hotspot. This is the spot where the month before my car had been rear-ended. As I was waiting at the traffic light, I could feel the heat through the floor of the car. I breathed a sigh of relief when the light turned green, but a while later on the highway, my knuckles around the steering wheel turned white. I was approaching another hot spot where not too long ago, I almost flipped my car, when I collided with a ladder that had fallen off the back of a truck.

So you see, as time goes on, it gets harder to find any spots on my way home that are not marred with bad memories. Some spots are so hot, that driving through them is too painful. Many years ago, I found my daughter in a diabetic coma, unconscious on the floor of her dorm. I have tried to rub that spot off, but it just won’t come out, even after all these years. That is definitely a dead zone, in my book. Read more...

Looking Back on the Coronavirus Pandemic - An Imaginary, Revisionist History



This is a satire based on an article entitled ‘The Deadly
Polio Epidemic and Why It Matters for Coronavirus’

The current 2050 Nipah pandemic may feel new to many of us, but it is strangely familiar to those who lived through the Coronavirus epidemic of the early 21st century.

The Coronavirus virus a.k.a. Covid19, arrived each winter, striking without warning. We knew how the virus was transmitted but there was uncertainty about its origin. There were wild theories that the virus had been purposely released from a lab in China. At the time, there was no known cure or vaccine.

Parents stopped sending their children to school for fear they would “catch coronavirus.” Swimming pools and movie theaters, beaches and shops were closed.

Because of a shortage of personal protective equipment (PPE), health workers would work without protection to save many a person’s life. The elderly, who seemed to be most at risk from the disease, were isolated in nursing homes and sometimes left to die without treatment.

The number of Covid19 cases in the U.S. peaked at 2 million, resulting in 103,000 deaths. Those who were critically ill with this highly infectious disease ended up intubated and were often left with permanent lung damage.

Ultimately, the coronavirus was conquered in 2022 by a vaccine. Donald Trump, who was our President at the time, signed an executive order forbidding the inventor from patenting his work, saying the vaccine belonged to the people and that to patent it would be like “patenting the sun.” Read more...
