About

   Hello, I am Danny. I am in the final stage of my Ph.D. in Physics at Scuola Normale Superiore in Pisa, Italy, where I conduct theoretical research on plasmonics and anisotropic metamaterials. In parallel, I work as a Police Inspector in the forensic department of the Italian Police in Rome, specializing in GSR analysis. However, my true passion is teaching, which blossomed during my undergraduate years. Since then, I have taught a variety of courses for talented high school students preparing for the Physics Olympiad, as well as for first-year university students. I also enjoy writing educational materials and articles that clarify complex concepts, challenge misconceptions, and debunk persistent myths often found in traditional sources; in the same vein, I plan to author a series of textbooks on Classical Physics, one of which is already in progress. I wish to dedicate my life to physics education.

   If you want to know more about my background and past experiences, here is my CV. If you would like to get in touch, you can reach me at daniele.provenzano@sns.it or via carrier pigeon.

Interests

   Since my master’s studies, I have been particularly interested in macroscopic electrodynamics, with a focus on the propagation of electromagnetic waves in anisotropic media. At the same time, having remained closely connected to the Physics Olympiad community—which I took part in during high school—I began teaching in three schools for gifted students, coaching them for national and international competitions (IPhO and EuPhO). Over six years of teaching, and through my involvement as a member of the organizing committees of both the Italian Physics Olympiad and the Team Physics Competition, I developed a strong passion for designing original educational materials. The need to create unique problems for competitions and exams eventually led several of them to evolve into the foundations of scientific articles.

   Currently, in addition to my Ph.D. research, I am working on some projects in two fields that I particularly love: celestial mechanics and fluid dynamics. As for the latter, you can check this paper about daflating soap bubbles. It served as the theoretical basis for the final experimental examination of the 2025 Italian Physics Olympiad.

   The other works in fluid dynamics focus on debunking fake perpetual motion machines such as this one, on quantitatively describing how a Heron’s Fountain works, and on producing a comprehensive review/tutorial on Bernoulli’s equation in all its forms, with particular emphasis on common misconceptions. I recently realized that this topic is often poorly addressed in many textbooks and, above all, by the majority of teachers both at school and at university. For this reason, I am writing a proper guide on the subject… turbulence, despite its fascination, remains the toughest enemy! I also presented a short preview of this work at the GIREP-EPEC conference in Leiden: here are the slides (I recommend using Adobe Acrobat for the magnus effect animation).

Deflating bubbles

This simulation illustrates the deflation process of a soap bubble through a cylindrical straw, considering three different straw lengths. The animation was created by my lifelong friend Antonino Cilione and is based on my results in this paper.

Heron's fountain

This video shows the operation of a HF that I built this summer, which is the subject of a article I am writing. As soon as the top cap is removed, the liquid flows downward, increasing the pressure in the lower container and causing the fluid to rise in the right-hand tube.


   As for celestial mechanics, I am modeling the dynamics of binary star systems (which exchange mass with each other) using simple ODEs and generalizing some results obtained by Sir James Jeans a century ago. Finally, still within the realm of motions in central fields, I am attempting to prove a beautiful property of the following orbits, each corresponding to the force field $\vec{f} \propto - \,r^{-n}\,\hat{r}$.

Teaching

During my years as a university student and Ph.D. candidate, I developed a deep passion for teaching physics. I began teaching immediately after earning my bachelor's degree, and it has since become an indispensable part of my life. I take inspiration from influential educators such as David Morin, David Griffiths, Kirk McDonald, Nicholas Wheeler, Michael Spivak and Giuseppe La Rocca, my professor at SNS. As for problem-solving, I have to bow to the Hungarian professors of the Loránd Eötvös Physical Society, who have been producing an astonishing number of original problems and organizing countless physics competitions for decades. They, too, are a great source of inspiration for me!

Here, you can find a collection of notes and exercises I have written over the past six years.

Projects

Here are some projects related to Physics education—all the blue links redirect to Italian websites.

When it comes to collective initiatives, I am especially grateful to my peers, Fabio Zoratti and Giovanni Maria Tomaselli. Fabio is an outstanding leader, while Gimmy is simply the best (young) physicist I know. They not only gave me the opportunity to participate in these projects but also taught me so much!

“Problem-Solving Techniques in Physics, with Original Problems and Debunked Myths”

In my free time, I am writing a textbook on problem-solving techniques, aimed at students taking part in Physics Olympiads and university freshmen. It will be specifically designed to debunk some common myths and correct many misconceptions often found in traditional teaching and textbooks. So far, I have written about 200 pages. I plan to finish by 2027.

Danny and Tony's Lab

Together with a computer scientist friend, I am developing a fully custom-built virtual and interactive physics laboratory hosted on a website. The platform will allow users to perform a variety of physics experiments within a 3D environment where they can walk around and interact with the apparatus. Some of these experiments are of my own design—several of which have been, or will be, presented in my educational publications—and cover topics in both classical and modern physics. The experiments will be simulated computationally, allowing users to adjust the relevant parameters and visualize in real time how the physical phenomenon gets modified. One section of the lab will include an astronomical observatory for celestial mechanics simulations. So far, we have developed a few fluid dynamics simulations, such as one on deflating soap bubbles and another on Heron’s fountain.

Italian Physics Olympiad

The Italian Physics Olympiad has been organized since 1987 by the Italian Association for the Teaching of Physics (AIF). Each year, two teams composed of the best Italian students are trained in preparation for the IPhO and EuPhO. In 2019, I joined the training courses organized by AIF as a trainer. After five years of collaboration, I earned a position on the national board that organizes the Olympiad. Our main tasks include designing theoretical and experimental problems for the various stages of the competition, evaluating contestants and coaching the two teams for the international competitions. Each year, roughly 30.000 high school students from all corners of Italy take part in the competition. The national finals take place in April in Senigallia, where there is also time to humiliate young contestants at beach soccer.

Physics School in Pisa

Since 2018, a dedicated group of physics students from Scuola Normale Superiore has been organizing an annual one-week physics school for 24 handpicked Italian high school students. The aim is to prepare them for the Physics Olympiad while providing an introduction to bachelor studies, both in the classroom and the laboratory. Lecture notes and recordings are available on the website, in Italian. In 2019, the project received the prize "Didactics of Physics," presented annually by the Italian Society of Physics. This project has been extremely important to me, as I met many people I care about.

Training Camp for the Physics Olympiad in Catania

Since 2019, students from Scuola Superiore di Catania have been organizing a physics training camp for students from southern Italy who qualify for the national stage of the Physics Olympiad. The camp features theoretical lessons, problem-solving sessions, hands-on experiments and a final competition. I joined the organizing team in 2023, forging great friendships with the young physicists from Catania.

Team Physics Competition

In 2023, after four years of preparation, my university colleagues and I gave birth to the first-ever Team Physics Competition, an annual event consisting of several stages held all across Italy and aimed at high school students. Every year, approximately 600 teams from all corners of Italy participate in the competition. The top 20 teams receive an invitation to the national finals, where the competition unfolds in person, resembling a sporting event. Here is the time-lapse of the 2024 final, can you spot the Easter egg?

Here is a funny problem I created for the 2025 contest: "Captain Hector Barbossa has a special spyglass made up of two thin converging lenses aligned along the same axis. The peculiarity of his instrument is that the magnification does not depend on the distance from the observed object. If the two lenses are separated by 11 cm and the focal length of the lens closest to the eyes is 1.8 cm, what is the angular magnification of the spyglass?"

“And now for something completely different”

  • My sister and I grew up in the countryside, surrounded by goats, pigs, chickens, and rabbits. My maternal grandparents were farmers, and during elementary and middle school, I loved helping them in their vegetable garden, while my sister took care of the bunnies and kittens (she's now a veterinarian). My relatives taught me how to work the land, harvest crops, and—most importantly—make do. I never learned to drive the tractor, but I loved riding pigs! Here’s my three-and-a-half-year-old self, grooming his humble steed and preparing it for battle against the monsters of his imagination. Back then, I had much more hair than I do now 😱.

    After building a treehouse and endless wooden soccer goals with my friends, I became interested in DIY. Now, besides gardening, climbing trees and chopping wood, I really enjoy tackling household issues, especially plumbing problems. In 2023, I almost got electrocuted after successfully fixing the motor of the washing machine. These are the risks of the trade!

  • I was raised on Bud Spencer & Terence Hill movies, but my childhood hero was Nicolas Cage.Over time, my tastes have changed. In the past few years, I’ve become a huge fan of Alfred Hitchcock, Sergio Leone, and Terry Gilliam, and my favorite kind of cinema is thriller and horror, a genre whose peak, I believe, was reached by the Italian gialli of the 1970s, like Dario Argento's. Here are my favorite movies, more or less in order.


  • Inspired by Monty Python's cheerful insanity, during the Ph.D. I discovered a passion for creating and editing absurd short films. You can find a couple on my YouTube channel. I have many more ideas that never came to life—the main obstacle being that my friends are not willing to act!

  • When it comes to music, my favourite composers are Ennio Morricone, Piero Piccioni, Brian Wilson, and Ray Davies. During the pandemic, I discovered the fascinating world of Progressive Rock. Since then, I have become a huge admirer of bands like Yes, Caravan, King Crimson, early Genesis, RTF and VDGG. I enjoy playing their songs on the bass guitar, even though some are still too challenging. Here’s a list of my favorite music albums (not just prog), roughly in order.


  • When it comes to sports, my tastes are fairly ordinary. I go running regularly and play soccer quite often, even as a goalkeeper. I learned to play with my neighborhood friends during my teenage years, on a dirt field we maintained ourselves. A few of us (including me) ended up in the hospital more than once, with broken arms and head injuries. Each time, our lovely mothers were furious and ready to give us a piece of their mind. A few years later, watching Ronnie "The Rocket" O'Sullivan play snooker on TV sparked my interest in the world of billiards. I love playing 8-ball and 9-ball, although I still haven’t mastered sidespin—and probably never will!
