    Weekly Quotation: Sunday, May 31, 2026: The Key to a Joyful Career

    For your consideration:

    Your work is going to fill a large part of your life, and the only way to be truly satisfied is to do what you believe is great work. And the only way to do great work is to love what you do. If you haven’t found it yet, keep looking. Don’t settle. As with all matters of the heart, you’ll know when you find it.

    – Steve Jobs

    The secret to success in what you do is to find your passion. It is not always the career that earns you the highest salary or a significant title; it is the one that brings you the most joy and fosters personal growth. A career that encourages you to become the best version of yourself. A career that brings you joy as well as those you serve is, in my view, the key to happiness.

    Speaking from experience, it is very easy to get caught up in trying to meet the expectations of the world around us: to solve the next challenge, earn the highest salary, receive the quickest promotions, that we get lost; we miss out on the true meaning of our lives. It is only when we pause and, through self-reflection, evaluate who we are and who we want to be that we change the course of our lives to pursue our passions. It is the most courageous thing you and I may ever do.

  • The Power of Grace: Key to Personal Growth

    The Power of Grace: Key to Personal Growth

    What is Grace? 

    Grace is just about being kind, patient, and forgiving without anyone having to earn it. It means choosing not to beat yourself up (or someone else) when things don’t go perfectly, or expectations aren’t met.

     I see grace as a foundational element of our character that requires constant tending as we grow into the best person we can be. It is critical in our relationships, whether it is with our loved ones, coworkers, or those we may supervise. I see it as a function of our self-awareness and a result of our perspective on life and how we perceive ourselves.


    Offering Grace to Others

    Offering grace to others means choosing kindness and patience in the situation, even when your expectations aren’t met. Start by assuming positive intent—believing that, for the most part, people do not intend to cause harm—and try to recognize that everyone deals with “stuff” you may not see or know about, such as stress, fatigue, or past experiences that influence their behavior. Choose to cultivate the long-term success of your relationship over the temporary satisfaction of winning an argument, and you may nurture deeper connections. A practical and, at times, very difficult way to implement this is to “pause,” wait ten seconds before reacting to someone else’s negative reaction or response. This brief interval provides you with the necessary mental and emotional clarity to ensure a compassionate, thoughtful response that triumphs over an immediate, impulsive reaction.


    Offering Grace to Yourself

    Grace is a result of how we perceive ourselves, and self-grace is often the toughest form of kindness to master because most people are their own harshest critics, demanding a level of perfection we would never expect of a friend. 

    When I fall short of my own high expectations—whether in my writing, personal habits, relationships with family and friends, or the goals I set for myself—self-grace serves as the crucial remedy for shame. Guilt might correctly tell us that we did something bad, but shame goes even further and wrongly whispers, “You are bad.” Grace steps in to remind us that we are human. Without grace offering this form of self-kindness, our foundation of self-confidence can become fragile, leading to emotional and physical stress. But by actively choosing grace, we can maintain our self-integrity, allowing us to reset, recalibrate, and try again without the burden of past mistakes holding us back. When we have a healthy level of self-awareness, we recognize our own intellectual, emotional, and physical limits. If we are honest about our own tendencies for making mistakes, we cannot deny the same margin for error to others. In this sense, grace is the ultimate act of intellectual and emotional honesty. 

    Growing into the “best person we can be” implies a path of continuous improvement. However, growth is rarely linear; it involves loops, plateaus, and declines. Grace is the tool that allows us to navigate those non-linear moments. It provides the “buffer” needed to handle life’s conflicts without burning out or becoming cynical.


    Grace as it Applies to STEM Students

    Life is full of major shifts, much like a “phase transition” in physics, where something changes from one state to another—think of ice turning into water. You might start with a high-pressure, “solid” focus on career and salary, but eventually, you move to a more “fluid,” rewarding state focused on things like family, helping others (“paying it forward”), or, like me, a personal passion like gardening. This process reveals that your life’s “vector,” with its direction and magnitude (where you’re headed, and how fast you’ll succeed, for example), will change, and it’s completely fine to stop chasing the title of “smartest in the room” and instead aim to be the “kindest” person. Remember that perfection is a myth; it’s unattainable. The real goal, your personal true North Star, is finding internal peace, which comes from aligning your life with what truly matters, not the size of your salary. In fact, this idea connects directly to how you approach subjects like science and math, where precision over performance is key: the integrity of your data and the exactness of your logic are always more important than rushing to an answer.


    My Shift in Perspective

    “The meaning of life. The wasted years of life. The poor choices of life. God answers the mess of life with one word: ‘grace.’”

    – Max Lucado

    My perspective on life has changed in the last 10 years. I now find grace in my personal relationship with God. When I  recognize and acknowledge the mistakes I’ve made in the past, God’s grace has saved me. 

    Additionally, I’ve lived enough life to recognize that grace is not the lowering of standards, but the management of the human element required to meet them. For example, I’m currently tackling this massive project of turning my blog posts into a cohesive book, and honestly, it’s a huge challenge. I feel this constant pressure—like trying to maintain a certain “velocity”—that always seems to clash with the reality of writing. There’s a definite mental and emotional “tug-of-war” inside me because I have super high standards.  When my progress doesn’t match my own strict deadlines, I now choose to be kind to myself. It’s about remembering that even though I want to finish fast, the most important thing is the quality of the work. I prioritize the quality of work and its concepts since I want this book to be a tool for my grandsons and granddaughter as they enter their middle and high school STEM courses.  And sometimes that means slowing down and giving myself a break. Showing myself grace by letting the work rest is essential, because it’s not just about finishing the book; it’s about modeling self-awareness and showing them that it’s okay for “first drafts” to need serious editing—that process is valuable, and having the wisdom to take my time is more important than rushing to be “perfect”.


    Conclusion

    Grace, combined with wisdom, is the capstone of our personal growth. The major component of wisdom is acknowledging that there is “grace”. Grace in knowing you don’t have to be perfect, that there are many paths to reaching a goal. And, grace in knowing that the goals you have today will be in constant flux as you grow older. But the ultimate goal is to find “peace” in who you are and what is most important to you. Your passions in life will change, as mine have as I’ve grown older. From the goal of career, making the highest salary, being the smartest person in the room, to focusing on my grandchildren, my gardening, and paying it forward through my writing.

    Weekly Quotation: May 13, 2026: Embracing Who I Am Today

    For your consideration,

    “I may not have gone where I intended to go, but I think I have ended up where I needed to be.”

    – Douglas Adams, author of “The Hitchhiker’s Guide to the Galaxy.”

    Embracing where we are today requires a degree of maturity – a perspective on our life’s travels, our ups and downs, our wins and losses, our successes and our mistakes, and a realization that every step was part of a larger purpose. There were times I looked back at my own career and second-guessed nearly every turn I took. Yet my journey back to my faith in Christ has given me a profound understanding of “grace.” It is the grace God extends to me, and the grace I must learn to give myself, acknowledging that being human means being imperfect. Every mistake has been a lesson, shaping me into who I am in this moment. I don’t strive to be “perfect”; instead, I simply pray that each new day finds me more compassionate and wiser than the day before.

  • The STEM Toolbox: Tools 1 & 2: The Golden Ratios

    The STEM Toolbox: Tools 1 & 2: The Golden Ratios

    Introduction

    In our metaphorical STEM toolbox, there are two main compartments: the analytical skills compartment and the personality traits compartment, i.e., compassion, humility, resilience, and perseverance.

    We have already discussed one of the analytical skills, translative communication. The next two tools we must sharpen aren’t gadgets or pieces of hardware; they are our own mental processes and insight. I bring these to your attention because I learned of their importance through my personal experiences during my first and second years of college.


    For example:

    Imagine you’re sitting in a chemistry class, and your teacher asks you to calculate the mass of  100mLs100 \;mLs of water, and you spend several minutes carefully punching numbers into your calculator, only to proudly raise your hand and announce to the class that a 100mL100\;mL volume of water weighs 10kilogramsor10,000grams.10\;kilograms\;or\;10,000\;grams.

    You don’t question your result. You don’t pause to consider that you’ve just described a volume that has the same mass as 10 1-liter bottles of water or 20 pounds of sugar. Sometimes we trust the “black box” in our hands more than our own common sense. This is the danger of the $130 Calculator: when the battery dies, or a decimal point is misplaced, we’re lost, we’re left without a good answer. How easy it is to forget that the best calculator we have is the one between our ears.


    Personal Commentary

    I attended high school during the early 1970s, and at the time, calculators did not play the same role in the classroom as they do today. As a matter of fact, throughout my high school years, I never owned one. I either wrote out the calculations on paper or used a slide rule. There was no such thing as a graphing calculator in my high school or college years, so all our graphs were hand-drawn. This gave me a tremendous advantage not only on my ACT exam but also throughout my career.

    It was not until my freshman and sophomore chemistry courses that I learned the importance of the following tools for my STEM toolbox. These tools may seem simple, but I guarantee they will save you time and prevent numerous mistakes in your calculations.


    Sidebar: Mass vs Weight

    In your middle and high school science classes (especially Chemistry and Physics), you spend a lot of time learning that mass and weight are different. It can be confusing because when you place an object on an analytical balance, the result, what we traditionally designate as “weight” of the object, reads in grams or kilograms, the units of mass.

    Remember –

    Mass is Matter: Mass is the measurement of how many atoms are packed into an object. It is an intrinsic property. If you take a 10-gram sample of copper to the Moon, Mars, or the center of the galaxy, it still has a mass of 10 grams because the “amount of copper” hasn’t changed.

    Weight is a Force: Weight is a measure of the gravitational tug-of-war between the Earth and your sample. Because gravity isn’t the same everywhere (it’s slightly weaker on top of a mountain than at sea level), your “weight” actually changes depending on where you are.

    How Does an Analytical Balance Work?

    An analytical balance is a complex instrument that converts the “weight” of an object, which has the units of Newton’s in the MKS system, to the units of “mass”, grams or kilograms, based upon the strength of the Earth’s gravitational field at that location.


    The Golden Ratios


    Golden Ratio #1: The Chemist’s “Compass”: “The “1-1-1” Rule.

    Before you touch the keypad of your calculator, you should memorize the “The 1:1:1 Rule.” For liquid water at standard conditions, there is a perfect, elegant relationship that serves as a universal “Fact Check”:

    1mL(capacity)=1gram(mass)=1cm3(volume)1\;mL\;(capacity)=1\;gram\;(mass)=1\;cm^3\;(volume)

    If you can visualize this concept, you can calculate with certainty. 1mL1\;mL of water is roughly the size of a standard sugar cube (1cm3)(1\;cm^3). If you hold that “cube” of water in your hand, it has a mass of exactly 1gram1\;gram. does the 1:1:1 Rule apply to your work? In the lab, the 1-1-1 Rule confirms that your math is correct. 

    Example 1:

    If you calculate that 50mLs50\;mLs of a dilute aqueous solution is equivalent to 5000grams5000\;grams, you can refer back to this rule. “If 1mLis1gram1\;mL \;is \;1\;gram, how can 50mLsbe5,000grams\;50\;mLs\;be\;5,000\;grams? You’ve just described a liquid denser than lead. 

    Example 2:

    If you calculate that 250mLs250\;mLs of distilled water has a mass of 5,000grams5,000\;grams, the 1-1-1 Rule screams at you: “Wait! 250mL250\;mL should be about 250grams250\;grams. Something is wrong by a factor of twenty!”

    This is more than simply math; it’s spatial reasoning. The 1:1:1 Rule turns abstract numbers back into physical objects. It bridges the gap between the metric prefixes that trip so many students up.

    It is the ultimate “Reality Check.”


    The Golden Ratio #2: Finding the “Micro” in the “Milli”

    To truly understand and master the concept of scale, we have to go smaller, from milliliters down to microliters (1/1000 of a milliliter). The second “Golden Ratio” to understand and then memorize  is the Drop:

    1drop=˙50microliters(1/1000milliliter)1\;drop\.=\;50\;microliters\;(1/1000\;milliliter)

    This ratio should help you realize that 1mL1\;mL isn’t just a number; it’s about 20 drops from a pipette. When you see 500microliters500\;microliters in a lab procedure or on an exam, you should immediately think “10 drops,” not just a string of zeros. This mental translation turns a cold calculation into a physical action.


    Conclusion

    The next time you are working in the lab and are asked to determine the mass of water needed to fill a container, try this: first, look at the volume of your container. Estimate the required mass of water using the 1-1-1 Rule. Then, and only then, use the calculator.

    If the calculator disagrees with your gut, don’t assume your gut is wrong. Check your decimal points.
