To my mind, nothing beats the sights of the World’s oceans.
In the past, I spent four years living on a yacht, a Tradewind 33, out in Cyprus. During that time I cruised to Turkey, to Greece, to Algiers, and loved it.
Here’s an extract from World Oceans day website.
Why Earth’s oceans are so important
Earth’s oceans are critical to human survival. Indeed, more than half the oxygen in our atmosphere is generated via photosynthesis by phytoplankton and seaweed in oceans. In addition, millions of people depend on fish and other marine animals for food. Research on some marine organisms has led to the development of new medications. Moreover, ocean currents, known as global conveyor belts, help regulate Earth’s climate.

George Monbiot published an article in The Guardian recently that was as hard-hitting as I have ever read from him.
I found it very powerful even though I have not been living in England since 2008. Mr Monbiot has previously given me permission to republish his articles and here it is.

Four-Year Plan
Posted on 3rd June 2025
Keir Starmer has accidentally given us four years in which to build a new political system. We should seize the chance.
By George Monbiot, published in the Guardian 27th May 2025
This feels terminal. The breaches of trust have been so frequent, so vast and so decisive that the voters Labour has already lost are unlikely to return. In one forum after another, I hear the same sentiments: “I voted for change, not the same or worse.” “I’ve voted Labour all my life, but that’s it for me.” “I feel I’ve been had.”
It’s not dissatisfaction. It’s not disillusionment. It’s revulsion: visceral fury, anger on a level I’ve seldom seen before, even towards Tory cruelties. Why? Because these are Tory cruelties, delivered by a party that claimed to be the only alternative, in our first-past-the-post electoral system.
Like many people, I was wary of Keir Starmer. I had limited expectations, but I willed Labour to succeed. So I’ve watched aghast as he and his inner circle have squandered one of the greatest opportunities the party has ever been granted. They seem to despise people who voted for them, while courting and flattering those who didn’t and won’t.
The results? Last week, the polling company Thinks Insight & Strategy found that 52% of those who voted Labour in the 2024 general election are considering switching to the Liberal Democrats or the Greens. That’s more than twice as many as might migrate to Reform UK. The research group Persuasion UK estimates that Labour could lose 250 seatsas a result of this flight to more progressive parties (again, more than twice as many as it could lose through voters shifting to Reform). Figures compiled by the progressive thinktank Compass show that Labour would lose its majority on just a 6% swing. Already, while it won a massive majority on a measly 34% vote at the election, it now polls at just 22%.
What explains this idiocy? Labour has succumbed, quickly and hard, to the defining sickness of our undemocratic political system: the sofa cabinet system of close advisers. Opaque and unaccountable government favours opaque and unaccountable power. Ever receptive to the demands of rentiers, oligarchs, non-doms and corporations, Labour’s oh-so-clever strategists are moronically giftwrapping the country for Nigel Farage.
Governments don’t start conservative and turn radical. The cruelty will set like concrete. The likely result is annihilation in 2029. On this trajectory, it might not be surprising if Labour were left with seats in only double figures.
Perhaps it’s a blessing that Starmer has shown his hand so soon, as we now have four years in which to prepare. I’m not a party person: for me, it’s a question of what works. And now we can clearly see the shape of it.
The Compass analysis, published in December, reveals extreme electoral volatility. This is caused by a combination of public fury towards austerity, exclusion, rip-off rents and startlingly low rates of wellbeing, and the “democratic mayhem” resulting from a first-past-the-post system in which five parties are now polling at 10% or more. Small vote shifts in this situation can cause wild fluctuations in the allocation of seats.
The report points out that the UK is an overwhelmingly progressive nation: in all but one election since 1979 most voters have supported left or centre-left parties. Of 15 nations surveyed, the UK has the extraordinary distinction of being both the furthest to the left and the most consistent elector of rightwing governments. Why? Because of our first-past-the-post system, which is grossly unfair not by accident but by design. Labour refuses to change it, as it wants to rule alone. The result is that most of the time it doesn’t rule at all.
The thinktank was hoping to mobilise the progressive majority around a revitalised Labour party, but that moment has passed. What the figures show, however, is massive potential for more radical change. A YouGov survey reveals that almost twice as many people want proportional representation in this country as those who wish to preserve the current system. So let’s build a government of parties that will introduce it.
Here’s the strategy. Join the Lib Dems, Greens, SNP or Plaid Cymru. As their numbers rise, other voters will see the tide turning. Encourage troubled Labour MPs to defect. Most importantly, begin the process in each constituency of bringing alienated voters together around a single candidate. This is what we did before the last election in South Devon, where polls had shown the anti-Tory vote evenly split between Labour and the Lib Dems. Through the People’s Primary designed by locals, the constituency decided to back the Lib Dems. The proof of the method can be seen less in the spectacular routing of the Conservatives (as similar upsets occurred elsewhere) than in the collapse in Labour’s numbers, which fell from 17% in 2019, and 26% in a poll before the primary began, to 6% in the 2024 election. The voters took back control, with startling results.
Whether you fully support any of these parties is beside the point. This coalition would break for ever the lesser-of-two-evils choice that Starmer has so cruelly abused, and which has for so long poisoned politics in this country. Game the system once and we’ll never have to game it again.
No longer will we be held hostage, no longer represented by people who hate us. It will be a tragedy if, as seems likely, Keir Starmer has destroyed the Labour party as a major political force. But it will be a blessing if he has also destroyed the two-party system.
Proportional representation is explained in detail here. There is also an explanation on WikiPedia here. From which I quote a small section:
Proportional representation (PR) refers to any electoral system under which subgroups of an electorate are reflected proportionately in the elected body. The concept applies mainly to political divisions (political parties) among voters. The aim of such systems is that all votes cast contribute to the result so that each representative in an assembly is mandated by a roughly equal number of voters, and therefore all votes have equal weight. Under other election systems, a bare plurality or a scant majority in a district are all that are used to elect a member or group of members. PR systems provide balanced representation to different factions, usually defined by parties, reflecting how votes were cast. Where only a choice of parties is allowed, the seats are allocated to parties in proportion to the vote tally or vote share each party receives.
That is a timely and powerful article from George Monbiot.
When my son, Alex, and Lisa, were with us in the second half of last month, they spoke of the tremendous joy they experienced in visiting Yellowstone before they came to us.
A shard of smooth bone etched with irregular marks dating back 20,000 years puzzled archaeologists until they noticed something unique – the etchings, lines like tally marks, may have represented prime numbers. Similarly, a clay tablet from 1800 B.C.E. inscribed with Babylonian numbers describes a number system built on prime numbers.
As the Ishango bone, the Plimpton 322 tablet and other artifacts throughout history display, prime numbers have fascinated and captivated people throughout history. Today, prime numbers and their properties are studied in number theory, a branch of mathematics and active area of research today.
Informally, a positive counting number larger than one is prime if that number of dots can be arranged only into a rectangular array with one column or one row. For example, 11 is a prime number since 11 dots form only rectangular arrays of sizes 1 by 11 and 11 by 1. Conversely, 12 is not prime since you can use 12 dots to make an array of 3 by 4 dots, with multiple rows and multiple columns. Math textbooks define a prime number as a whole number greater than one whose only positive divisors are only 1 and itself.
Math historian Peter S. Rudman suggests that Greek mathematicians were likely the first to understand the concept of prime numbers, around 500 B.C.E.
Around 300 B.C.E., the Greek mathematician and logician Euler proved that there are infinitely many prime numbers. Euler began by assuming that there is a finite number of primes. Then he came up with a prime that was not on the original list to create a contradiction. Since a fundamental principle of mathematics is being logically consistent with no contradictions, Euler then concluded that his original assumption must be false. So, there are infinitely many primes.
The argument established the existence of infinitely many primes, however it was not particularly constructive. Euler had no efficient method to list all the primes in an ascending list.
Prime numbers, when expressed as that number of dots, can be arranged only in a single row or column, rather than a square or rectangle. David Eppstein/Wikimedia Commons
In the middle ages, Arab mathematicians advanced the Greeks’ theory of prime numbers, referred to as hasam numbers during this time. The Persian mathematician Kamal al-Din al-Farisi formulated the fundamental theorem of arithmetic, which states that any positive integer larger than one can be expressed uniquely as a product of primes.
From this view, prime numbers are the basic building blocks for constructing any positive whole number using multiplication – akin to atoms combining to make molecules in chemistry.
Today, primes in this form are called Mersenne primes after the French monk Marin Mersenne. Many of the largest known primes follow this format.
Several early mathematicians believed that a number of the form (2p – 1) is prime whenever p is prime. But in 1536, mathematician Hudalricus Regius noticed that 11 is prime but not (211 – 1), which equals 2047. The number 2047 can be expressed as 11 times 89, disproving the conjecture.
While not always true, number theorists realized that the (2p – 1) shortcut often produces primes and gives a systematic way to search for large primes.
The search for large primes
The number (2p – 1) is much larger relative to the value of p and provides opportunities to identify large primes.
When the number (2p – 1) becomes sufficiently large, it is much harder to check whether (2p – 1) is prime – that is, if (2p – 1) dots can be arranged only into a rectangular array with one column or one row.
Fortunately, Édouard Lucas developed a prime number test in 1878, later proved by Derrick Henry Lehmer in 1930. Their work resulted in an efficient algorithm for evaluating potential Mersenne primes. Using this algorithm with hand computations on paper, Lucas showed in 1876 that the 39-digit number (2127 – 1) equals 170,141,183,460,469,231,731,687,303,715,884,105,727, and that value is prime.
Also known as M127, this number remains the largest prime verified by hand computations. It held the record for largest known prime for 75 years.
Researchers began using computers in the 1950s, and the pace of discovering new large primes increased. In 1952, Raphael M. Robinson identified five new Mersenne primes using a Standard Western Automatic Computer to carry out the Lucas-Lehmer prime number tests.
As computers improved, the list of Mersenne primes grew, especially with the Cray supercomputer’s arrival in 1964. Although there are infinitely many primes, researchers are unsure how many fit the type (2p – 1) and are Mersenne primes.
By the early 1980s, researchers had accumulated enough data to confidently believe that infinitely many Mersenne primes exist. They could even guess how often these prime numbers appear, on average. Mathematicians have not found proof so far, but new data continues to support these guesses.
George Woltman, a computer scientist, founded the Great Internet Mersenne Prime Search, or GIMPS, in 1996. Through this collaborative program, anyone can download freely available software from the GIMPS website to search for Mersenne prime numbers on their personal computers. The website contains specific instructions on how to participate.
GIMPS has now identified 18 Mersenne primes, primarily on personal computers using Intel chips. The program averages a new discovery about every one to two years.
The largest known prime
Luke Durant, a retired programmer, discovered the current record for the largest known prime, (2136,279,841 – 1), in October 2024.
Referred to as M136279841, this 41,024,320-digit number was the 52nd Mersenne prime identified and was found by running GIMPS on a publicly available cloud-based computing network.
This network used Nvidia chips and ran across 17 countries and 24 data centers. These advanced chips provide faster computing by handling thousands of calculations simultaneously. The result is shorter run times for algorithms such as prime number testing.

The Electronic Frontier Foundation is a civil liberty group that offers cash prizes for identifying large primes. It awarded prizes in 2000 and 2009 for the first verified 1 million-digit and 10 million-digit prime numbers.
Large prime number enthusiasts’ next two challenges are to identify the first 100 million-digit and 1 billion-digit primes. EFF prizes of US$150,000 and $250,000, respectively, await the first successful individual or group.
Eight of the 10 largest known prime numbers are Mersenne primes, so GIMPS and cloud computing are poised to play a prominent role in the search for record-breaking large prime numbers.
Large prime numbers have a vital role in many encryption methods in cybersecurity, so every internet user stands to benefit from the search for large prime numbers. These searches help keep digital communications and sensitive information safe.
I find it unbelievable that there are prizes for the first 100 million-digit prime number and also the first 1 billion-digit prime number. It is so far away from my understanding of these numbers that all I can say is: I find it unbelievable!
NASA hasn’t landed humans on Mars yet. But thanks to robotic missions, scientists now know more about the planet’s surface than they did when the movie, The Martian, was released.
Our human knowledge is constantly growing. In many, many directions. Here is a fascinating (well it is to me!) article from The Conversation.
ooOOoo
A decade after the release of ‘The Martian’ and a decade out from the world it envisions, a planetary scientist checks in on real-life Mars exploration
‘The Martian’ protagonist Mark Watney contemplates his ordeal. 20th Century Fox
Andy Weir’s bestselling story “The Martian” predicts that by 2035 NASA will have landed humans on Mars three times, perfected return-to-Earth flight systems and collaborated with the China National Space Administration. We are now 10 years past the Hollywood adaptation’s 2015 release and 10 years shy of its fictional timeline. At this midpoint, Mars exploration looks a bit different than how it was portrayed in “The Martian,” with both more discoveries and more controversy.
Although concepts for crewed missions to Mars have gained popularity, NASA’s actual plans for landing humans on Mars remain fragile. Notably, over the last 10 years, it has been robotic, rather than crewed, missions that have propelled discovery and the human imagination forward.

Robotic discoveries
Since 2015, satellites and rovers have reshaped scientists’ understanding of Mars. They have revealed countless insights into how its climate has changed over time.
As Earth’s neighbor, climate shifts on Mars also reflect solar system processes affecting Earth at a time when life was first taking hold. Thus, Mars has become a focal point for investigating the age old questions of “where do we come from?” and “are we alone?”
The Opportunity, Curiosity and Perseverance rovers have driven dozens of miles studying layered rock formations that serve as a record of Mars’ past. By studying sedimentary layers – rock formations stacked like layers of a cake – planetary geologists have pieced together a vivid tale of environmental change that dwarfs what Earth is currently experiencing.
Mars was once a world of erupting volcanoes, glaciers, lakes and flowing rivers – an environment not unlike early Earth. Then its core cooled, its magnetic field faltered and its atmosphere drifted away. The planet’s exposed surface has retained signs of those processes ever since in the form of landscape patterns, sequences of layered sediment and mineral mixtures.

Arabia Terra
One focus of scientific investigation over the last 10 years is particularly relevant to the setting of “The Martian” but fails to receive mention in the story. To reach his best chance of survival, protagonist Mark Watney, played by Matt Damon, must cross a vast, dusty and crater-pocked region of Mars known as Arabia Terra.
In 2022 and 2023, I, along with colleagues at Northern Arizona University and Johns Hopkins University, published detailed analyses of the layered materials there using imagery from the Mars Reconnaissance Orbiter and Mars Odyssey satellites.
By using infrared imagery and measuring the dimensions of surface features, we linked multiple layered deposits to the same episodes of formation and learned more about the widespread crumbling nature of the terrain seen there today. Because water tends to cement rock tightly together, that loose material indicates that around 3.5 billion years ago, that area had a drying climate.
To make the discussions about this area easier, we even worked with the International Astronomical Union to name a few previously unnamed craters that were mentioned in the story. For example, one that Watney would have driven right by is now named Kozova Crater, after a town in Ukraine.
More to explore
Despite rapid advances in Mars science, many unknowns remain. Scientists still aren’t sure of the precise ages, atmospheric conditions and possible signatures of life associated with each of the different rock types observed on the surface.
For instance, the Perseverance rover recently drilled into and analyzed a unique set of rocks hosting organic – that is, carbon-based – compounds. Organic compounds serve as the building blocks of life, but more detailed analysis is required to determine whether these specific rocks once hosted microbial life.
The in-development Mars Sample Return mission aims to address these basic outstanding questions by delivering the first-ever unaltered fragments of another world to Earth. The Perseverance rover is already caching rock and soil samples, including ones hosting organic compounds, in sealed tubes. A future lander will then need to pick up and launch the caches back to Earth.
Sampling Mars rocks could tell scientists more about the red planet’s past, and whether it could have hosted life.
Once home, researchers can examine these materials with instruments orders of magnitude more sensitive than anything that could be flown on a spacecraft. Scientists stand to learn far more about the habitability, geologic history and presence of any signs of life on Mars through the sample return campaign than by sending humans to the surface.
This perspective is why NASA, the European Space Agency and others have invested some US$30 billion in robotic Mars exploration since the 1960s. The payoff has been staggering: That work has triggered rapid technological advances in robotics, telecommunications and materials science. For example, Mars mission technology has led to better sutures for heart surgery and cars that can drive themselves.

Calling the red planet home?
Colonizing Mars has a seductive appeal. It’s hard not to cheer for the indomitable human spirit while watching Watney battle dust storms, oxygen shortages and food scarcity over 140 million miles from rescue.
Much of the momentum toward colonizing Mars is now tied to SpaceX and its CEO Elon Musk, whose stated mission to make humanity a “multi-planetary species” has become a sort of rallying cry. But while Mars colonization is romantic on paper, it is extremely difficult to actually carry out, and many critics have questioned the viability of a Mars habitation as a refuge far from Earth.
Now, with NASA potentially facing a nearly 50% reduction to its science budget, the U.S. risks dissolving its planetary science and robotic operations portfolio altogether, including sample return.
Nonetheless, President Donald Trump and Musk have pushed for human space exploration to somehow continue to progress, despite those proposed cuts – effectively sidelining the robotic, science-driven programs that have underpinned all of Mars exploration to date.
Yet, it is these programs that have yielded humanity’s richest insights into the red planet and given both scientists and storytellers like Andy Weir the foundation to imagine what it must be like to stand on Mars’ surface at all.

Do photons wear out? An astrophysicist explains light’s ability to travel vast cosmic distances without losing energy
My telescope, set up for astrophotography in my light-polluted San Diego backyard, was pointed at a galaxy unfathomably far from Earth. My wife, Cristina, walked up just as the first space photo streamed to my tablet. It sparkled on the screen in front of us.
“That’s the Pinwheel galaxy,” I said. The name is derived from its shape – albeit this pinwheel contains about a trillion stars.
The light from the Pinwheel traveled for 25 million years across the universe – about 150 quintillion miles – to get to my telescope.
My wife wondered: “Doesn’t light get tired during such a long journey?”
Her curiosity triggered a thought-provoking conversation about light. Ultimately, why doesn’t light wear out and lose energy over time?
Let’s talk about light
I am an astrophysicist, and one of the first things I learned in my studies is how light often behaves in ways that defy our intuitions.
The author’s photo of the Pinwheel galaxy. Jarred Roberts
Light is electromagnetic radiation: basically, an electric wave and a magnetic wave coupled together and traveling through space-time. It has no mass. That point is critical because the mass of an object, whether a speck of dust or a spaceship, limits the top speed it can travel through space.
But because light is massless, it’s able to reach the maximum speed limit in a vacuum – about 186,000 miles (300,000 kilometers) per second, or almost 6 trillion miles per year (9.6 trillion kilometers). Nothing traveling through space is faster. To put that into perspective: In the time it takes you to blink your eyes, a particle of light travels around the circumference of the Earth more than twice.
As incredibly fast as that is, space is incredibly spread out. Light from the Sun, which is 93 million miles (about 150 million kilometers) from Earth, takes just over eight minutes to reach us. In other words, the sunlight you see is eight minutes old.
Alpha Centauri, the nearest star to us after the Sun, is 26 trillion miles away (about 41 trillion kilometers). So by the time you see it in the night sky, its light is just over four years old. Or, as astronomers say, it’s four light years away. Imagine – a trip around the world at the speed of light.
With those enormous distances in mind, consider Cristina’s question: How can light travel across the universe and not slowly lose energy?
Actually, some light does lose energy. This happens when it bounces off something, such as interstellar dust, and is scattered about.
But most light just goes and goes, without colliding with anything. This is almost always the case because space is mostly empty – nothingness. So there’s nothing in the way.
When light travels unimpeded, it loses no energy. It can maintain that 186,000-mile-per-second speed forever.
It’s about time
Here’s another concept: Picture yourself as an astronaut on board the International Space Station. You’re orbiting at 17,000 miles (about 27,000 kilometers) per hour. Compared with someone on Earth, your wristwatch will tick 0.01 seconds slower over one year.
That’s an example of time dilation – time moving at different speeds under different conditions. If you’re moving really fast, or close to a large gravitational field, your clock will tick more slowly than someone moving slower than you, or who is further from a large gravitational field. To say it succinctly, time is relative.
Even astronauts aboard the International Space Station experience time dilation, although the effect is extremely small. NASA
Now consider that light is inextricably connected to time. Picture sitting on a photon, a fundamental particle of light; here, you’d experience maximum time dilation. Everyone on Earth would clock you at the speed of light, but from your reference frame, time would completely stop.
That’s because the “clocks” measuring time are in two different places going vastly different speeds: the photon moving at the speed of light, and the comparatively slowpoke speed of Earth going around the Sun.
What’s more, when you’re traveling at or close to the speed of light, the distance between where you are and where you’re going gets shorter. That is, space itself becomes more compact in the direction of motion – so the faster you can go, the shorter your journey has to be. In other words, for the photon, space gets squished.
Which brings us back to my picture of the Pinwheel galaxy. From the photon’s perspective, a star within the galaxy emitted it, and then a single pixel in my backyard camera absorbed it, at exactly the same time. Because space is squished, to the photon the journey was infinitely fast and infinitely short, a tiny fraction of a second.
But from our perspective on Earth, the photon left the galaxy 25 million years ago and traveled 25 million light years across space until it landed on my tablet in my backyard.
And there, on a cool spring night, its stunning image inspired a delightful conversation between a nerdy scientist and his curious wife.
This remark jumped out at me when I first read the article: ‘In the time it takes you to blink your eyes, a particle of light travels around the circumference of the Earth more than twice.’
Alex, my son, and his partner, Lisa, are coming to see us later today. They arrived in Portland on Sunday, 11th but first of all wanted to see Yellowstone.
Vision to Reality: Building a Profitable Vet Clinic
Launching a veterinary clinic is a significant endeavor that requires meticulous planning and strategic decision-making. This venture combines a passion for animal care with the intricacies of managing a successful business. Aspiring clinic owners must navigate several critical steps to lay a strong foundation and ensure operational excellence. Starting your own clinic promises not only to fulfill a dream of helping animals but also to establish a thriving enterprise in the community.
Build a Strong Foundation with an Effective Marketing Strategy
A robust marketing strategy is essential to attract potential clients in the digital era. Establishing a professional online presence through a user-friendly website that details your services, team, and location builds trust among pet owners. Engage actively on social media with regular updates and client testimonials to showcase your expertise and commitment to animal care. Forge partnerships with local pet-related businesses to increase visibility and drive traffic to your clinic, enhancing both your and your partners’ customer bases.
Craft a Clear and Detailed Business Plan
A well-constructed business plan acts as your clinic’s roadmap, detailing your mission, services offered, and the specific target market. Identify your niche early—whether it’s specializing in certain animals or treatments—to attract the appropriate clientele. Include comprehensive financial projections and a marketing budget in your plan to ensure financial preparedness and support your clinic’s promotional activities.
Enhance Your Business Knowledge by Pursuing an MBA
Running a veterinary clinic demands a blend of clinical and business expertise. Pursuing a master’s of business administration online can boost your proficiency in key business areas such as strategy, management, and finance. An MBA not only deepens your understanding of business operations but also enhances leadership skills and self-assessment capabilities. These competencies are essential for balancing the medical and business demands of your clinic, ensuring its long-term success.
Safeguard Your Business with Proper Insurance
Operating a veterinary clinic comes with inherent risks, making comprehensive insurance coverage essential. Essential policies include malpractice insurance to handle legal issues and general liability insurance for accidents on your premises. Property insurance is crucial to protect your clinic’s infrastructure and equipment against unexpected events. Consulting with an insurance expert can ensure that you have thorough coverage to protect against potential financial setbacks.
Invest in High-Quality Veterinary Equipment
Providing top-tier care necessitates investing in high-quality veterinary equipment. Essential tools like X-ray machines, surgical instruments, and lab equipment should be of the highest standard to ensure accurate diagnoses and treatments. Modern technologies, such as digital imaging systems, not only enhance patient care but also improve operational efficiency. While the initial cost may be higher, investing in quality equipment pays off in the long run by boosting efficiency and minimizing errors.
Secure the Necessary Funding for Your Clinic
Securing sufficient funding is critical when starting a veterinary clinic. Estimate your startup costs accurately to understand your financial needs, including equipment, premises, staffing, and marketing. Explore diverse financing options, such as bank loans, private investors, and specialty medical practice loans that might offer favorable terms. Adequate initial funding prevents cash flow problems and supports your clinic’s growth trajectory.
Choose the Right Location for Your Clinic
The location of your clinic is pivotal to its success, necessitating a spot with a high demand for veterinary services. Conduct thorough market research to choose a community rich in pet owners who need your services. Select a location that is accessible, visible, and has ample parking to ensure convenience for your clients. Proximity to complementary services like pet groomers or dog trainers can further enhance client traffic and provide expansion opportunities.
Opening a veterinary clinic is both challenging and rewarding, demanding a careful blend of dedication and strategic foresight. Success in this field not only enhances the well-being of pets but also contributes positively to the local community. It requires ongoing commitment to adapt and grow in a dynamic environment. Ultimately, the fulfillment of running a successful veterinary clinic comes from both the impact on animal health and the achievement of entrepreneurial goals.

Opening a vet clinic is well beyond me even though many years ago I was an entrepreneur.
However, one hopes that somewhere a person or two find this very useful.
How then do we practice gratitude during such times?
I am a social psychologist who runs the Positive Emotion and Social Behavior Lab at Gonzaga University. I teach courses focused on resilience and human flourishing. I have researched and taught about gratitude for 18 years.
At the best of times, awareness of the positive may require more effort than noticing the negative, let alone in times of heightened distress. There are, however, two simple ways to work on this.
Generally, negative information captures attention more readily than the positive. This disparity is so potent that it’s called the negativity bias. Researchers argue that this is an evolutionary adaptation: Being vigilant for life’s harms was essential for survival.
Yet, this means that noticing the kindnesses of others or the beauty the world has to offer may go unnoticed or forgotten by the end of the day. That is to our detriment.
Gratitude is experienced as a positive emotion. It results from noticing that others − including friends and family certainly, but also strangers, a higher power or the planet − have provided assistance or given something of value such as friendship or financial support. By definition, gratitude is focused on others’ care or on entities outside of oneself. It is not about one’s own accomplishments or luck.
Thus, it may assist in counteracting the negativity bias by helping us find and remember the good that others are doing for us every day − the good that we may lose sight of in the best of times, let alone in times when Americans are deeply stressed.
But it’s also clear that gratitude can be cultivated through practice. People can improve their ability to notice and feel this positive emotion.
One way to do this is to try a gratitude journal. Or, if the idea of journaling is daunting or annoying, perhaps call it a daily list instead. If you have given this a try and dislike it, skip to the second method below.
Gratitude lists are designed to create a habit in which you scan your day looking for the positive outcomes that others have brought into your life, no matter how small. Writing down several experiences each day that went well because of others may make these positive events more visible to you and more memorable by the end of the day − thus, boosting gratitude and its accompanying benefits.
While the negative news − “The stock market is down again!” “How are tariffs going to affect my financial security?” − is clearly drawing attention, a gratitude list is meant to help highlight the positive so that it doesn’t go overlooked.
The negative doesn’t need help gaining attention, but the positive might.
A second method for practicing gratitude is expressing that gratitude to others. This can look like writing a letter of gratitude and delivering it to someone who has made a positive impact in your life.
When my students do this exercise, it often results in touching interactions. For instance, my college students often write to high school mentors, and those adults are regularly moved to tears to learn of the positive impact they had. Expressing gratitude in work settings can boost employees’ sense of social worth.
In a world that may currently feel bleak, a letter of gratitude may not only help the writer recognize the good of others but also let others know that they are making a beautiful difference in the world.
I like the suggestions for practicing gratitude and I am going to reproduce that last sentence from Monica, namely: ‘In a world that may currently feel bleak, a letter of gratitude may not only help the writer recognize the good of others but also let others know that they are making a beautiful difference in the world.
I would add sending an email to that person as well is a good move.
Every week, millions of Americans toss their recyclables into a single bin, trusting that their plastic bottles, aluminum cans and cardboard boxes will be given a new life.
But what really happens after the truck picks them up?
Plastics are among the biggest challenges. Only about 9% of the plastic generated in the U.S. actually gets recycled, according to the Environmental Protection Agency. Some plastic is incinerated to produce energy, but most of the rest ends up in landfills instead.

So, what makes plastic recycling so difficult? As an engineer whose work focuses on reprocessing plastics, I have been exploring potential solutions.
How does single-stream recycling work?
In cities that use single-stream recycling, consumers put all of their recyclable materials − paper, cardboard, plastic, glass and metal − into a single bin. Once collected, the mixed recyclables are taken to a materials recovery facility, where they are sorted.
First, the mixed recyclables are shredded and crushed into smaller fragments, enabling more effective separation. The mixed fragments pass over rotating screens that remove cardboard and paper, allowing heavier materials, including plastics, metals and glass, to continue along the sorting line.

Magnets are used to pick out ferrous metals, such as steel. A magnetic field that produces an electrical current with eddies sends nonferrous metals, such as aluminum, into a separate stream, leaving behind plastics and glass.
The glass fragments are removed from the remaining mix using gravity or vibrating screens.
That leaves plastics as the primary remaining material.
While single-stream recycling is convenient, it has downsides. Contamination, such as food residue, plastic bags and items that can’t be recycled, can degrade the quality of the remaining material, making it more difficult to reuse. That lowers its value.
Having to remove that contamination raises processing costs and can force recovery centers to reject entire batches.

Which plastics typically can’t be recycled?
Each recycling program has rules for which items it will and won’t take. You can check which items can and cannot be recycled for your specific program on your municipal page. Often, that means checking the recycling code stamped on the plastic next to the recycling icon.
These are the toughest plastics to recycle and most likely to be excluded in your local recycling program:
Symbol 3 – Polyvinyl chloride, or PVC, found in pipes, shower curtains and some food packaging. It may contain harmful additives such as phthalates and heavy metals. PVC also degrades easily, and melting can release toxic fumes during recycling, contaminating other materials and making it unsafe to process in standard recycling facilities.
Symbol 4 – Low-density polyethylene, or LDPE, is often used in plastic bags and shrink-wrap. Because it’s flexible and lightweight, it’s prone to getting tangled in sorting machinery at recycling plants.
Symbol 6 – Polystyrene, often used in foam cups, takeout containers and packing peanuts. Because it’s lightweight and brittle, it’s difficult to collect and process and easily contaminates recycling streams.
Which plastics to include
That leaves three plastics that can be recycled in many facilities:
Symbol 5 – Polypropylene, PP, used in products such as pill bottles, yogurt cups and plastic utensils.
However, these aren’t accepted in some facilities for reasons I’ll explain.
Taking apart plastics, bead by bead
Some plastics can be chemically recycled or ground up for reprocessing, but not all plastics play well together.
Simple separation methods, such as placing ground-up plastics in water, can easily remove your soda bottle plastic (PET) from the mixture. The ground-up PET sinks in water due to the plastic’s density. However, HDPE, used in milk jugs, and PP, found in yogurt cups, both float, and they can’t be recycled together. So, more advanced and expensive technology, such as infrared spectroscopy, is often required to separate those two materials.
Once separated, the plastic from your soda bottle can be chemically recycled through a process called solvolysis.
It works like this: Plastic materials are formed from polymers. A polymer is a molecule with many repeating units, called monomers. Picture a pearl necklace. The individual pearls are the repeating monomer units. The string that runs through the pearls is the chemical bond that joins the monomer units together. The entire necklace can then be thought of as a single molecule.
During solvolysis, chemists break down that necklace by cutting the string holding the pearls together until they are individual pearls. Then, they string those pearls together again to create new necklaces.
Other chemical recycling methods, such as pyrolysis and gasification, have drawn environmental and health concerns because the plastic is heated, which can release toxic fumes. But chemical recycling also holds the potential to reduce both plastic waste and the need for new plastics, while generating energy.
The problem of yogurt cups and milk jugs
The other two common types of recycled plastics − items such as yogurt cups (PP) and milk jugs (HDPE) − are like oil and water: Each can be recycled through reprocessing, but they don’t mix.
If polyethylene and polypropylene aren’t completely separated during recycling, the resulting mix can be brittle and generally unusable for creating new products.
Chemists are working on solutions that could increase the quality of recycled plastics through mechanical reprocessing, typically done at separate facilities.
One promising mechanical method for recycling mixed plastics is to incorporate a chemical called a compatibilizer. Compatibilizers contain the chemical structure of multiple different polymers in the same molecule. It’s like how lecithin, commonly found in egg yolks, can help mix oil and water to make mayonnaise − part of the lecithin molecule is in the oil phase and part is in the water phase.
In the case of yogurt cups and milk jugs, recently developed block copolymers are able to produce recycled plastic materials with the flexibility of polyethylene and the strength of polypropylene.
Improving recycling
Research like this can make recycled materials more versatile and valuable and move products closer to a goal of a circular economy without waste.
However, improving recycling also requires better recycling habits.
You can help the recycling process by taking a few minutes to wash off food waste, avoiding putting plastic bags in your recycling bin and, importantly, paying attention to what can and cannot be recycled in your area.
