My Favorite YouTube

I admit to being an avid YouTube watcher. While I find lots of interesting, amusing, and educational videos on the site I do have my favorites. I recommend that you try them out.

Sampson Boat Co

Sampson Boat Co

These videos follow Leo Goolden as he rebuilds the pilot cutter, TALLY HO, from the rotting keel up into an ocean-going wooden sailboat, with the intention of partaking in the world famous Fastnet yacht race in 2027, 100 years after TALLY HO won the race in 1927. When he purchased the boat in 2017 for $1, she was a rotten hulk, but over the next 7 years, with the help of a lot of amazing people, he rebuilt TALLY HO from the keel up – documenting and funding the process through his YouTube videos. TALLY HO is now sea worthy and the adventure continues with a huge voyage ahead of her as she is sailed from the state Washington, where she was rebuilt, through the Panama Canal and across the Atlantic Ocean to England to qualify and partake in the Fastnet.

The Australian Armour & Artillery Museum

Australian Armor

The Australian Armour and Artillery Museum opened to the public on Saturday the 6th of September 2014. The museum is privately owned and is the largest museum of its kind in the southern hemisphere. They are in a suburb of Cairns, North Queensland, Australia. They are dedicated to the collection, preservation, restoration and display of Armored Vehicles and Artillery from the 1800’s to the present day, including exhibits from the USA, UK and USSR. The collection includes armored vehicles and artillery from both world wars with a particular focus on WWII. Currently the collection consists of over 200 armored vehicles and artillery pieces, many of which will not be found anywhere else in Australia. They are constantly on the lookout for additional pieces of equipment that will make the museum a richer experience for those visiting. They produce a video every week entitled, Workshop Wednesday, where they show current activities in their restoration workshops.

Midlife Stockman

Midlife Stockman

Sean Stockman had a bit of a midlife crisis when he decided to devote some of his time to helping his community in a unique way. He searches around the poorer neighborhoods of Detroit to find homes of the less fortunate that badly need a landscaping makeover. After seeking permission from the home’s resident, he cleans up the landscaping, cutting the grass, edging and trimming the trees and shrubbery, all for free. His activities and those who support them form a community of help that believes that they can do more by working together. As you watch his videos you will see the needs of real people, and how cleaning up their yard and cutting their lawn can greatly improve their condition.

The Death of Reason

I have lived in the United States of America for almost half my life, immigrating here from The United Kingdom and becoming a US citizen. During my time here I have noticed a number of changes since my arrival, not least the not so gradual change from political thinking based in reason to an age of politics more based on emotional thinking.

The Age of Reason, or the Enlightenment, was a notable era in world history that heavily influenced modern philosophy and government. It was a 17th–19th century intellectual movement emphasizing reason, science, and individualism, promoting rational thought and skepticism over tradition. Its core philosophy focused on replacing superstition with science and skepticism. Its key thinkers include John Locke, Voltaire, Rousseau, Thomas Paine, and Jefferson who advocated for liberty, constitutional government, and the separation of church and state.

The Age of Reason, or Enlightenment, generally ended in the late 18th century, with most historians citing the French Revolution or the start of the Napoleonic Wars as its conclusion. The movement gave way to Romanticism, which emphasized emotion, nationalism, and individual experience over the empiricism and strict rationality of the Enlightenment.

The difference between logical thinking and emotional thinking are that logical thinking is an objective, slow, and analytical process focused on facts, data, and long-term consequences, whereas emotional thinking is a subjective, rapid, and reactive process rooted in personal feelings, values, and immediate survival needs. Balancing both, often called “wise mind,” is ideal because logic offers structure while emotions provide insight into care and motivation. Sadly, I detect that this balance is rapidly fading from American politics.

Rational vs Emotional Thinking

Emotional thinking, or emotional reasoning, causes individuals to treat feelings as facts, leading to distorted perceptions of reality, flawed decision-making, and increased anxiety. By relying on emotions rather than objective evidence, people often experience negative thought cycles, strained relationships, and reduced workplace performance.

There are significant consequences of emotional thinking including a distorted reality where feelings are interpreted as truth; Impulsive decision making based on a temporary emotional state; a worsening of anxiety, depression and low self-worth; misinterpreting the actions of others because of personal emotional states causing conflict and resentment.

Emotional thinking in American politics, driven by anger, anxiety, and moral conviction, has created a deeply polarized environment, accelerating affective polarization where opposing sides are viewed as immoral or threats. This emotional surge increases civic engagement, such as voting and volunteering, but also fosters the spread of misinformation, the normalization of political violence, and severe declines in mental health.

Citizens increasingly view opposing parties not merely as wrong, but as immoral, unintelligent, and a direct threat to the country, leading to increased hostility. This can cause people to more likely to accept and share misinformation that aligns with their partisan identities. In addition, emotional distress, coupled with conspiratorial thinking, is linked to a higher tolerance for political violence and a willingness to reject democratic norms.

While often viewed negatively, scholars note that emotions like passion, hope, and empathy are also vital for driving political participation and democratic engagement, not just hostility. However, the current political landscape is heavily dominated by affective polarization, where the emotional distance between groups is rising

The consequence of these changes over the years is that many don’t want to be confused by facts and data that contradict their internal feelings. They are chained to their beliefs and do not wish to be deviated from them regardless of objective reality. There’s also a great amount of political lying occurring to both support and challenge those beliefs. It’s becoming more and more difficult to winnow out the objective truth from a barrage of falsehood. While I stubbornly cling to my search for empirically supported objective truth in a sea of lies, other grab the nearest ‘fact’ that fits their worldview to run with. I long for the America that was and weep for the country it has become and is becoming.

The Fat Shot

About a year ago I got tired of being called obese. I got tired of my doctor’s short intake of breath when he checked by BMI number and my blood glucose level. I would claim to have gotten tired of the TV talking heads and their self-superiority when discussing obesity, but I got tiered of them long since for their hypocrisy and their certitude about subjects they can barely spell far less understand, but I digress. Suffice it to say I took on a scunner[1] about the subject.

A little background on my previous eating habits. My father was a POW during WWII for almost five years from June 1940 until May 1945. He was held in a POW camp in Poland. Most of the time they had little to eat. From late 1944 through 1945 until their liberation the POWs had almost nothing to eat. It will therefore be no surprise that I was brought up in a clear your plate household, just like many Americans whose parents endured the Great Depression. That’s where I developed my eating habit of finishing all that was put in front of me.

A large minority of our population have lots to say about obesity and have little reserve about sharing their opinions, especially with folks who are a pounds over a fashionable weight. These ectomorphs[2] are critical of those of us who are efficient consumers of calories, that sometimes causes us to be obese. It turns out that obesity is a chronic, complex disease defined by excessive body fat, typically diagnosed with a BMI of 30 or higher. It is caused by an energy imbalance from high-calorie diets, sedentary lifestyles, genetics, and metabolic conditions, often resulting in severe health risks like diabetes, heart disease, and cancer. Treatment often involves lifestyle changes, medication, or surgery.

I do admit to a sedentary lifestyle. Since I despise those who spends their waking hours in the gym, building a body image concomitant with their aspirational vision of who they should be, losing weight through exercise didn’t appeal to me. By comparison with the gym rats, I just live my life, spending my free time reading books about scientific topics and world history, and occasional brain candy, RC sailboat racing, and riding my E-bike, not activities that take me to the gym. However, in recent times our pharmaceutical industries have developed medications for weight reduction, the so-called Fat Shots.

The Fat Shot consists of a glucagon-like peptide-1 (GLP-1) receptor agonist that is highly effective and is an FDA-approved medications for type 2 diabetes and for chronic weight management. By mimicking a natural hormone, these medications reduce appetite, slow gastric emptying, and improve insulin secretion, leading to significant weight loss and lowered blood sugar. Sounded good to me so I arranged with my doctor to get the Fat Shot.

I won’t tell you which one I chose to use other than it is a name you would probably recognize, but not the two best known ones. It comes in a self-injection gadget that you stab yourself with in a fatter part of your anatomy. It doesn’t hurt and is over in a second. You start at a low dose with an injection once per week, and the dose is increased by month depending on your reaction to the medication.

While it reduces food cravings and does aid weight loss, it does have side effects. The most common adverse effects listed are gastrointestinal, including nausea, diarrhea, vomiting, and constipation. They do not mention digestive gas, both upward and downward. I was most affected by diarrhea and gas, lots of gas, enough to cause a measurable increase in global warming.

The positive side is that my blood glucose fell from the mid 130’s to less than 90, and my weight has so far fallen from a high of 215lbs, a BMI of 35, to 170lbs, a BMI of 26, all in about six months. I certainly feel better and fitter and have more energy to do stuff. I am about to end my shots and will record any rebound, which I hope to avoid. I’ll be sure to post an update of how I get on.

[1]  Scunner – a Scottish word meaning a strong, deep-seated dislike, aversion, or a person/thing causing disgust.

[2] Ectomorphs — An ectomorph is a body type characterized by a naturally lean, slender frame, fast metabolism, and difficulty gaining weight or muscle. Known as “hardgainers,” they typically have narrow shoulders/hips and low body fat. They thrive on high-calorie, nutrient-dense diets and resistance training to build mass.

How Does Gravity Suck?

When I was in high school gravity was simple, when I got to university it got complicated, but I still don’t know how gravity sucks.

In high school we were taught Newton’s gravity. Newton explained gravity as a force of attraction between two bodies that had mass. This force was proportional to the product of the masses (their values multiplied together) and divided by the distance between them squared. I was happy with that explanation, and it was perfectly adequate to get us to the moon and back. I did have a reservation that the masses used for gravity were the same as the masses used in Newton’s laws of motion. Much later I found out that this question is called the Principle of Equivalence and has perplexed much smarter people than me.

Newton’s Gravity

Just to make this post more scientific let my present Newton’s equation of gravity:

Newton’s Gravity Equation

where G is the universal gravitational constant, m1 and m2 are the masses and r the distance between them

That doesn’t look too hard to understand or use but it does pose several philosophical questions, particularly the one I started with, what sucks?

Despite some reservations Newton’s law of gravity works for most things, like predicting the orbits of planets to predicting the trajectories of rockets and inter-planetary satellites. That being the case why do we need an alternative, improved version?

It turns out that Newton’s gravity may provide computational accuracy for most gravity questions, it fails to answer some deep philosophical questions. These questions include answering how gravity provides action at a distance. How do the two masses know about each other’s size and how far apart they are? How fast is the force? Is it instant or limited in speed?

When Einstein published his theory of Special Relativity the speed of gravity was settled at the speed of universal causality, the same as the speed of light. The question remained on what was swapped between the masses that transmitted the gravitational force, and the Equivalence Principle remained an open question.

Then Einstein presented his theory of General Relativity to the world, and everything changed. Not only did this theory predict and explain the precession of the orbit of Mercury around the sun, a topic that was not in the forefront of thought of the general public at that time and isn’t today, and a behavior that was not explained by Newton’s gravity. It also explained gravity’s action at a distance and the Equivalence Principle.

Einstein’s Gravity

General Relativity claims that mass curves spacetime and spacetime guides mass. In simple terms, it is mass that tells spacetime how to curve, and it is spacetime that tells mass how to move. These claims are wrapped up in Einstein’s equation of General Relativity shown below:

Einsteins Gravity Equation

Where:

 

This is a tensor equation and is obviously much more complicated that Newton’s equation, which perhaps explains why we use Newton’s equation if we can.

However, here’s where I get to my pet peeve. Einstein’s Equation for gravity says that mass (or energy) bends spacetime and that bent spacetime directs the mass/energy how to move, but what are they saying to each other? How are mass and spacetime communicating with each other? What is it that mass communicates to spacetime to persuade it to bend, and what power does spacetime have to make mass follow it’s suggested direction? In a nutshell, how does gravity suck?

Smarter people than me state that mass/energy IS spacetime, but that is beyond my ability to understand. I need a simpler explanation than that. I suppose I’ll just keep wondering how mass/energy sucks on spacetime to make it bend and how spacetime sucks on mass/energy to direct its motion. I guess I’m either dense or stubborn, or perhaps both.

A Brick for my Dad

Our Veterans Memorial Garden

There are many bricks in the veteran’s memorial plaza where I live in Texas each with a different name and a different story. The brick I want to talk about looks a bit different than the rest and I hope to explain why, and why it sits with all the others.

It all started with a trip to Hawaii to celebrate our 40th anniversary. My wife and I flew to Honolulu a day early so that we could visit the USS Arizona Memorial before we headed off on a seven-day islands cruise. We got on the coach to Pearl Harbor early in the morning and were entertained by our driver with multiple tales of the islands and tourists like us. When he asked for questions one of our numbers asked him why so many Japanese visited the Arizona Memorial. I must admit to a moment of apprehension anticipating his answer but when it came it was quite unlike my unworthy expectations. He asked us all to think about how our world was changed by the Pearl Harbor attack and how the world was changed for the Japanese too. As I thought about his question I thought about my father and his circumstances on December 7th, 1941.

In December 1941 my mother and father were not yet engaged, far less married and I was not yet born. In fact, I was not even a twinkle since I was not born until 1949. On Pearl Harbor Day my father was in a German Army POW camp in Torun, Poland (Camp 17 of Stalag_XXI-A as I recall). Absent the attack his prospects of ever returning home to Scotland alive were vanishingly remote. It goes without saying that such a failure to return home would have seen my parents unmarried and me unborn, and this story unwritten.

The story of how he finished up as a POW is a tragic one, quite embarrassing to Winston Churchill’s reputation and greatly forgotten by military historians of WWII both in the USA and UK. He volunteered for the army in September 1939 the week that war was declared in the UK. He was inducted into the Seaforth Regiment and sent to Fort George, near Inverness in Scotland. After only 3 months training, he was issued a Lee Enfield bolt action rifle and 100 rounds of .303 ammunition and shipped out to France in January 1940 in the 4th Battalion Seaforth’s, part of the 51st Highland Division. The division was initially deployed as part of the British Expeditionary Force (BEF) in France near the Belgian border, then eventually stationed at the northern end of the Maginot Line near Metz, quite separate from the rest of the British Army. Those readers who are military historians will realize that the 51st HD location was a precarious one, although they didn’t know that at the time but soon would.

When the Phony War ended and the real shooting started around May 10th, 1940, the main German armored thrust landed north of the 51st HD, went through Sedan and onward to the English Channel coast near Calais, cutting the 51st off from the rest of the British Army. Elements of the 51st division did take part in supporting French armor assaults northward into the flank of the German penetration but without air support and after the German anti-tank forces worked out how to disable the heavily armored French tanks, these all failed.

The rest of the British Army was famously evacuated from the beaches of Dunkirk between May 27th and June 4th leaving the 51st HD the only British division left fighting in France (the 50th division was in the process of landing at Cherbourg but were soon turned around and sent back to the UK). The 51st, including my father, fell back along the line of the river Somme arriving near St Valery sur Somme on the English Channel coast by May 28th. They were soon engaged by strong mechanized and infantry forces. The danger of being outflanked by German armor on their right drove them slowly back toward their bases of supply at Le-Havre and Rouen. When these bases were cut off, they fell back to St Valery-en-Caux a small town on the channel coast where they attempted to hold a perimeter while awaiting to be rescued by sea.

St Valery Map

But rescue became impossible when the beaches came under direct artillery fire. They might have been saved if earlier action had been taken, but Churchill had delayed efforts to rescue the 51st and to keep them in the fight as a political bargaining tool with the French to keep them from capitulating; now it was too late.

On June 12th, 1940, the French forces supporting them surrendered and, absent food, fuel, ammunition and medical supplies, and with no embarkation possible the 51st was surrendered to the famous German general Erwin Rommel.

Gen Rommel and Gen Fortune

The 10,000 men of the division, mostly Scottish, were marched off as POWs to an uncertain future. At the time of this surrender the 51st Highland Division was surrounded by the 5th and 7th armored divisions, the 2nd motorized division, the 11th motorized brigade, the 57th, 31st, 12th, and 32nd infantry divisions of the German Army. A small force called Ark Force did escape through German lines to Le-Havre and returned to the UK, but my father was not one of the fortunate ones.

He and his buddies were stripped of all that was valuable the marched eastward toward Germany. Besides marching they were carried in coal barges, in trucks and finally by train in cattle cars to Torun, Poland which is near Gdansk, or Danzig as it was called in those days. Here they entered into the German camp system, in his case Stalag XXI-A.

Dad as POW, top row 2nd left

They were organized by service, rank and nationality. The British were treated better than most, albeit not all that well. They were issued rations of 1/5th of a loaf of black bread and a bowl of soup per day. Why 1/5th of a loaf is a mystery that only the Germans knew the answer to. At the beginning the bread was okay and the soup had recognizable vegetables and some protein in it. As time passed the ‘bread’ became sweepings and the soup became warm water.

As a private soldier my father was obliged to work in either the coal mines or on local farms. He volunteered to be a farm worker because it allowed him access to foodstuffs not available in camp that he could trade for. The POWs were sustained by Red Cross parcels, actually boxes, many supplied from the USA through Switzerland. They were supposed to receive one parcel per month but got far fewer, and sometimes none for months. The parcels contained cans of coffee, cans containing American cigarettes, cans of butter, chocolate, candies and other highly desirable products that were rarely consumed by the POWs but used as trade goods to swap for potatoes, carrots, eggs and other staples from local farmers. It was these staples that kept them alive through the next five years.

He escaped a few times; well, he walked away from the farm he was working on, but with little success. When recaptured, prisoners were yelled at, perhaps hit with a rifle butt a few times, and then they were sentenced to 21 days solitary in the camp prison, the cooler. His most successful escape attempt reached the docks at Gdansk where he and his buddy were caught climbing the dockyard fence next to a Swedish cargo ship. So, he was returned to the camp and his 21-day penance before heading out on the next work party to another farm. To my father it was all an adventure to escape the monotony of camp life. His family circumstances before he volunteered was rough, so I don’t think POW life was too unsettling for him, early on at least. He sent a postcard home to his sweetheart, my mother to be, consisting of a photograph of his hut and its residents and telling her that he was alive (I still have it). They corresponded by letter throughout his captivity maintaining their romance from afar. There is a family story that towards the end of the war, while he was again in solitary, he was informed by the guards that his older brother was in camp looking for him. Having been captured in Tobruk in North Africa and having had many adventures before pitching up in Poland his older brother, my uncle Jim got back to Scotland the same week as my dad.

In December 1941 my father had been a POW for over a year and a half. Although the Germans had attacked the Soviet Union in June that year the POWs had little hope of an end to the war in circumstances that would see them return home victorious, or indeed at all. Then Pearl Harbor happened and when Churchill was informed of the attack wrote that he “…went to bed and slept the sleep of the saved and thankful”. I suspect that the POWs had a similar reaction when they found out than America had entered the war on their side. But for this entry into the conflict, Germany would never have been defeated and my dad would never have been liberated.

Towards the end of 1944 and beginning of 1945 the camps in Poland were emptied and the POWs were rounded up and driven west to escape the advancing Soviet forces. This little-known episode is called “The March” by those who took part in it. Over a period of about four months from January to April, they were marched about back and forth across Poland and Germany for more than 500 miles in some of the most brutally cold conditions. There was very little food and those who fell out of line to raid a farmer’s field for some potatoes were often shot. Estimates vary but perhaps 80,000 allied POWs took part with between 2000 and 3000 that died on the way. One morning in late April or early May 1945 my father woke in a field near Hamburg. The guards had gone, and soon American forces arrived – he was free!

My dad returned home to Scotland and soon persuaded my mother to marry him. They settled down in central Scotland and raised two boys, my elder brother and me. Although he worked pretty much every day of his life my father’s health was affected by his time as a POW. He died young, not quite 55, and a little over a year after my mom died. She was barely in her 50’s when she died having been seriously ill since her early 30’s.

So, what has all this to do with a brick in our Veterans Memorial Garden? Well, I was telling a neighbor this tale a number of years back. He is a Vietnam veteran who was seriously wounded flying helicopters in the 1st Cavalry. He was interested in my dad’s story and my experience on the bus heading to the Arizona memorial. It was he who suggested the brick. So that is why the brick is there, not just to memorialize my father but to remind folks of what the others memorialized there have done to rescue freedom, and to place my dad’s name in a country he loved and among those who saved his life and who gave me mine.

Dad’s Brick

But for America and Americans, my dad would not have survived, and I would not have been born and would never have emigrated to the United States of America and become one of its citizens – and I would never then have placed the brick.

Bladder Cancer — the unfashionable disease

One of the downsides of getting old is getting sick. I never had any serious illnesses when younger and working. After I retired things changed. Like an old car my bits started to wear out and seize up.

We had moved into a retirement community when my wife retired, but I kept working. The community we moved to is like a vacation resort for geezers with lots of activities to pursue. After about a year commuting to work and back every day while missing out on all the fun to be had at home during the day, I decided to hang up my slide rule and retire.

In retirement I played golf as many as four times a week and renewed my long-lost interest in building and flying radio-controlled aircraft, drones, and sailboats. I also took up painting, mostly wild and colorful abstract cubist paintings in acrylic, and some oil on canvas of more demure subjects. I was taking full advantage of the activities that our community offered when I was diagnosed with bladder cancer.

I won’t go into the details here of how I found out I had bladder cancer, and the story of my treatment and complications. If you are interested in the gory details, you can find them in this attached story. Suffice it to say that I had a long journey with the disease, finally having my bladder and prostate removed to be replaced by a stoma and the exterior plastic urine bag that I wear today. It’s not a great solution but it’s tolerable and allows me to wake up each morning on the green side of the grass. A negative consequence of the surgery was the loss of function of my wedding tackle, but at my age that too is tolerable.

In the midst of this journey, I had a negative finding from a colonoscopy. They found something suspicious near the junction of my transverse colon and descending colon. After checking that this condition, unlike a fine wine, would not improve with age, I agreed to having partial colorectal surgery. The surgery was performed using a DaVinci robotic surgery machine. As a confirmed technophile I insisted in being introduced to this apparatus in the operating theatre before they turned my lights out. I awoke missing a few inches of my colon and with four ‘stab’ wounds in my lower abdomen, but no stoma and no bag – whoopee!

I don’t know what caused me to have the issue with my colon, but I do know what caused the bladder cancer, smoking cigarettes which I did for fifty years. Smoking causes about 90% of bladder cancers – who knew? My advice, beyond stopping, is that if you have incidence of dark pee, get tested. Bladder cancer is eminently treatable if caught early. If the cancer grows through the bladder wall into the muscle, then it becomes much more serious. To avoid colon cancer, get your regularly scheduled colonoscopies. Again, when caught early it is successfully treatable. Yes, I know the reluctance to go through the pre-colonoscopy purge process, but it’s better than a big stoma and colostomy bag, always assuming you survive that far.

So, in conclusion, the older you get, the more you need to take care of yourself. Stay fit and active and pay particular attention to your health and any symptoms of your stuff going wrong or breaking. Try to stay on the green side of the grass and have fun doing so.

What is Time?

In his book The Hitchhiker’s Guide to the Galaxy the author Douglas Adams’ character Ford Prefect states that ‘time is an illusion, lunchtime doubly so’. It turns out that Douglas Adams was more prescient than he perhaps imagined.

In contemporary quantum physics the nature of time is hotly debated and is generally unknown – an illusion perhaps. In her YouTube video Sabine Hossenfelder presents an overview of the current scientific understanding of What is Time.

It turns out that time is an enigma. We all think we know what it is, but our imaginings have no basis in science. We know that we can recall the past and only anticipate the future but beyond this our certainty evaporates.

From a scientific perspective time is imagined as a coordinate of the spacetime of General Relativity, Einstein’s theory of gravity. For macroscopic systems this kind of time may be adequate, but it seems that at the atomic scale where quantum theory applies, elementary particles operate without a knowledge of time. Indeed, they behave the same whether time runs forward or backward.

In our macroscopic world we measure time using clocks of various kinds. In this way we are made aware of the passage of time and the notion of causality where an action precedes a result. In the quantum world this relationship does not hold, we often see the consequence of an action occurring before its cause.

A scientific hero of mine, Emmy Noether discovered that the physical principle of the conservation of energy was the consequence of time reversal symmetry. She also discovered other physical conservation laws that were the consequence of other symmetries, Noether’s Theorem. This theorem is at the center of modern theories of the four forces of nature.

When it comes to clocks, we must take extreme measures to synchronize them together to establish a universal time. We are all familiar with the time zones of our daily lives, particularly when scheduling when to watch a sports event in another zone. What our human experience is mostly blind to is that clocks are subject to Einstein’s relativity, both special and general.

If we put an extremely accurate atomic clock in an aircraft and fly it at high speed, we notice that it seems to run slower than a matching atomic clock that is kept on the ground because of Special Relativity. We also note that an atomic clock that is carried into space some distance above the earth runs faster than one on the surface because of General Relativity. Both effects must be accounted for in the GPS satellites that we rely on for navigation. The system would otherwise be very inaccurate without the correction.

There does seem to be some connection between the direction of the flow of time and entropy, but entropy does not seem to be an explanation of the nature of time, especially when causality is compromised.

So far, our scientific explanations for the nature and origin of time have not yet produced a solution with wide acceptance in the scientific community. Some day we may have an answer, but it doesn’t appear that the answer will happen soon.

 

 

The UK Post Office Scandal

 

The UK Post Office Scandal was a massive miscarriage of justice where faulty Fujitsu’s Horizon software used by the UK Post Office falsely reported financial shortfalls occurring in sub-post offices, leading the Post Office to wrongly prosecute over 700 sub-postmasters for theft and false accounting. Many faced prison, bankruptcy, and severe distress, with 59 deaths of victims reported, at least thirteen of them suicides. So far, I’m aware of no member of the government or the software provider that has been imprisoned. This scandal has been called the UK’s most widespread miscarriage of justice.

The Post Office itself took many cases to court, prosecuting 700 people between 1999 and 2015. Another 283 cases were brought by other bodies, including the Crown Prosecution Service (CPS).

In 2017, a group of 555 sub-postmasters – led by campaigner Alan Bates, who was subsequently knighted — took legal action in a landmark court case against the Post Office. In 2019, the Post Office agreed to pay the group £58m in compensation, but much of the money went on legal fees.

However, the action paved the way for dozens of sub-postmasters to have their convictions quashed in 2021. The episode came to wider public attention at the start of 2024 when it was depicted in an ITV drama, Mr. Bates vs The Post Office.

A public inquiry into this scandal was chaired by Sir Wyn Williams. The inquiry found profound, widespread human suffering, including over 10,000 affected, ruined lives, and 13 potential suicides had been caused by the Post Office and its faulty software. As of September 2025, over £1.23 billion ($1.67 billion) in compensation has been awarded to more than 9,100 victims. The final version of the inquiry report is expected to be published in 2026.

This whole mess is a salutary lesson on the excesses of government persecution of its citizens, and the lengths people will go to CYA. The level of lying and deception presented to the statutory public inquiry is appalling, but, like always, the government covers its posterior with a straight face and a sociopathic attitude.

 

 

Malcolm Allan and MV San Delfino

Had he survived WWII Malcolm Allan would have become my uncle in-law on the marriage of my maternal uncle George to Malcolm’s sister Florence. Sadly, he did not survive the war, dying aboard the petroleum tanker San Delfino when it was torpedoed by a German submarine near Cape Hatteras in 1942.

During WWII the school leaving age in Scotland was at the age of 14. As such, when Malcolm left school, he was quickly drafted, not into the armed services, but into the Merchant Marine. After his first transatlantic voyage as a cabin boy, he was so terrified by his experience that while on leave, he refused to go back to sea. The local police came to his home, arrested him and he was forced to go to sea once more, this time aboard the MV San Delfino, an 8,072-ton tanker built in the UK in 1938.

Before the war, the tanker San Delfino worked routes from Mexico, the Gulf of Mexico, and the East Coast of the United States to the United Kingdom. At the outbreak of World War II, San Delfino underwent conversions to add a 4-inch deck gun mounted at the stern and four machine guns located both fore and aft. The vessel also carried two Hotchkiss machine guns and a Lewis machine gun, making it a formidable opponent to any U-boat.

Soon after Germany declared war with the United State on December 11, 1941, the German U-boat commander, Vizeadmiral Karl Dönitz, began plans to strike a swift and devastating blow on the United States’ eastern seaboard. His plan was called Operation Paukenschlag, also known as Operation Drumbeat. In late December, five U-boats set sail, and the first torpedo strike occurred on January 11. In early April 1942, Operation Drumbeat continued with a fourth wave of U-boats, including U-203, which arrived off the East Coast shortly after a fuel stop in the Azores.

In the early morning hours of April 9, 1942, as U-203 patrolled the waters, it spotted San Delfino traveling alone from Houston, Texas to Halifax, Nova Scotia and on to the United Kingdom. U-203 fired one torpedo, striking the starboard side near the number two or number three tank, instantly igniting some of the 11,000 tons of aviation fuel carried by San Delfino. A second explosion erupted, possibly from either the ammunition cargo or the weapons on board. Flames ignited all over the vessel.

The call to abandon ship was made and two lifeboats were lowered. One of the lifeboats, however, got caught in the current and was dragged into a pool of burning fuel, horrifically killing the 24 crew members and four gunners in the boat. Malcolm was in the second lifeboat. He was only 17 when he died. The master, 19 crew members and two gunners in the other lifeboat were picked up by HMS Norwich City (FY-229) and taken to Morehead City, North Carolina. Of the 50 crew members on board, 28 lost their lives because of the attack.

MV San Delfino lies in 110 feet of water at 35°23’52.04″N, 75°6’57.92″W off Cape Hatteras on the east coast of the USA. She is now a popular dive sight, and my uncle’s grave.

San Delfino Casualties

A Life a Long Time Ago

Once upon a time I was a research physicist working for a UK defense contractor. I took up this job fresh from three years as a post-Doc research assistant in a university. I had lost my interest in pure research and realized that I was much more suited to applied physics. My specialty at that time was lasers and electro-optics, topics that were rapidly entering into the defense industry at that time.

The research department in which I worked covered a wide range of applied sciences. In my section, our work was focused on the application of laser and electro-optic technology to anti-tank and anti-air missile systems. While I worked in both of these areas, and many others, I was particularly involved with anti-air systems.

The AA missile system we were building at that time was the Rapier Field Standard B (FSB). It consisted of a launcher mounting four missiles with a surveillance radar on top. The launcher could slew the missiles around the radar to the bearing of the detected target prior to firing.

Nearby the launcher was an optical tracker system that was used to track the target and guide the missile. It required that an operator acquire the target in this sight, track it, and fire the missile that was then guided by the optical sight to impact with the aircraft. The optical tracker could be augmented with a second tracking radar system that took over the duties of the operator to guide the missile to the target.

Having watched this process in action on the firing range it was an awesome sight. The missile would leave the launcher at supersonic speed within its own length and would be out of sight before I saw it move. Fortunately, they were programmed to miss the target drones otherwise we would quickly run out of expensive aircraft.

Our job was to perform the research investigations that would support the engineering required to upgrade and modernize this system. We were to investigate the use of lasers to perform ranging and as a replacement for the guidance microwave link. Additionally, we investigated the use of lasers, and electro-optic and thermal infra-red imagers to augment, replace, and automate the existing optical tracker system.

As a small and dedicated team, we worked hard and had a blast doing this work. We had the opportunity to operate the missile simulator and to attend and participate in many trials, including live fire trials as mentioned above.

I left the company before the new systems were produced but I recognize our fingerprints on the current versions of the system. It was a long time ago, more than forty years, but I still remember those times with fondness.
