Where Engineering Meets Expression

The Honesty of the Keys
I am an engineer and scientist by profession, trained to think in structure, precision, and proof. Piano draws on these same disciplines—practice, form, and control—while adding what science alone cannot provide: emotional expression and presence.
Piano is a unique full-body exercise, engaging brain, hands, posture, and memory. It is a rigorous pursuit of neuroplasticity and attention, requiring a level of mental agility that keeps the mind sharp as we age.
At the keyboard, there are no titles or past achievements—only the honesty of the present moment. It is the essential counterweight to my professional life: the space where the analytical mind finds its harmony.
My Favorite Music & Recordings
I enjoy exploring the works of many Baroque and Romantic composers.
I have been recently modernizing my piano repertoire to stay engaged with contemporary musical language while maintaining a strong connection to historical traditions.
Here are a few of my favorite recordings you can listen to or download:
Note: I am not a professionally trained musician; these recordings reflect my personal journey and passion for music. An example of the power of self-learning: with no formal opportunities, I reached Level 8 on the piano through dedication and practice.

Dancing or Fighting?
That's the Ultimate Question for our Future
The Polonaise is the most cherished Polish musical form. It defines our nobility, defying and heroism.
We are still civilized!
We are still remembered!
When Frédéric Chopin composed his Polonaise in A major, Op. 40 No. 1, he did not call it “Military.” Chopin conceived it to be played with vigor and dignity as a most distinguished dance of the Polish nobility. At the time, Poland had just suffered the brutally suppressed November Uprising of 1830 against Russian rule. This was not a moment to call the nation to arms again.
Over the years, however, the piece gradually acquired its “Military Polonaise” identity. Many of the greatest pianists—Arthur Rubinstein among them—have performed it in under seven minutes, emphasizing its martial, defiant character, almost as a war procession.
I choose a different path. I play it as a dance, not a battle—closer to 8.5 minutes—highlighting its ceremonial grandeur, nobility, and rhythmic poise rather than sheer aggression. For me, it is a dancing party with strength and pride, not a call to fight.
Shorter recordings, closer to the best and "fastest" and more aggressive piano players are being prepared with initial promising successes. Finally, I have found something important and useful to do in my retirement. I will keep you posted - 7.5 minutes, perhaps? I need to be a bit more aggressive and a little less peaceful. Against my nature!!!
Ten pages of terrifying-looking music, at least for an amateur, for less than seven minutes of sound.
Five pages for dancing (left)—and five pages for military fighting (rigth).
Crazy!
Passionate about Nature - Gardening in Denver
I have built a botanical garden in Denver with my own hands from scratch, right around my modest home—against the odds.
For 25 years, I dug, planted, cut grass, pruned, replanted, and began again, all while the Colorado climate seemed determined to challenge every botanical ambition. I planted many trees—some survived, some did not—but enough endured that the garden now tells its own story.
How much CO₂ has it captured over the years? How many tons of oxygen has it quietly released?
According to a rough estimate from AI (see the attached comprehensive ecological report from AI), this 8,000 ft² garden has sequestered many tons of CO₂ and also produced many tons of oxygen over its lifetime. The numbers are approximate, but their impact is far from trivial.
The garden exists. It grows, it breathes, it endures. You decide how it looks—and what it means.
Passionate about Nature - Mountain Ranching
High in the mountains of Colorado, at 8,600 feet, I have been mountain ranching since 2007. Just as in Denver, I have been using both my hands and no help from professional gardeners or others!
Between cross-country skiing, hiking, and mountain biking, my main daily responsibility is caring for my two-acre mountain ranch, full of trees, grass, and flowers—and for my trout—making sure my gorgeous Oscar Waterfall never obstructs their breeding, day or night. The water must flow freely, the fish must remain undisturbed, and the waterfall must look gorgeous!
Visit me there. You can enjoy a cup of coffee, sit on my large bridge, and—if you are patient enough—communicate with the trout, without any fishing, of course. I would even argue whose life has been more difficult and dangerous, theirs or ours.
Oxygen and Carbon Dioxide Balance of Denver and Mountain Gardens
Over decades, Maciej Kumosa’s urban garden and mountain ranch have sequestered over 90 tons of CO₂ and produced nearly as much oxygen, demonstrating the measurable environmental contribution one individual can make through sustained land stewardship.
For perspective, this is equivalent to roughly 6–7 years of emissions for one person or about 1.5–2 years for a family of four. While not offsetting global emissions, these systems exemplify the quiet power of long-term care for land, water, and biodiversity."
Despite major efforts, I cannot eliminate my carbon footprint using the top and bottom paradises.
Unless I eliminate all the natural grasses and plant several hundred large blue spruces (top picture) and replace (bottom picture) my beautiful lawns with more deciduous trees at the bottom. I do not think so! I love my grasses and my lawns!
According to the ecological report, a few additional acres of a subtropical jungle would solve my problem. Let me think about it more!

Beyond carbon and oxygen, the Denver Botanic Garden and Mountain Ranch have delivered disproportionate ecological and human benefits. Together, they have created long-term urban and alpine biodiversity refuges that support pollinators, birds, soil microorganisms, and native plant regeneration in environments otherwise dominated by lawns, pavement, or managed forests.
They have improved soil structure and water retention, reduced local heat and erosion, stabilized riparian ecology along the river, and enhanced downstream watershed quality.
In Denver, the garden mitigates urban heat, dust, and noise while demonstrating that intensive biodiversity is possible on a small residential footprint; in the mountains, the ranch preserves native grassland, protects aquatic habitat, and maintains ecological continuity at high elevation.
Equally important, both sites provide cultural and educational value - quietly modeling stewardship, restraint, and coexistence with nature - benefits that scale socially even when biophysical metrics do not.
