There is a scene that plays out in boardrooms and co-working spaces around the world, though few of the people involved have ever named it. A founder stands before a whiteboard, marker in hand, facing a group of investors who are trying to decide whether this particular person is worth betting on. The founder begins to speak — about a problem, about a solution, about a market that does not yet fully understand what it needs — and something happens that is hard to define but easy to recognise. The founder is not just describing a business. They are deriving it. Building it from first principles, step by logical step, the way you would build a proof in physics. The investors may not know that this habit of mind was formed years ago, at a desk in a school library, wrestling with problems from the British Physics Olympiad. But it is there, beneath the surface, shaping everything about how this person thinks.
This is not a story about physics. It is a story about how a particular way of thinking — the way of thinking that the BPhO rewards — turns out to be startlingly well-suited to the world of entrepreneurship and innovation. If you are a student preparing for the BPhO, this is about what you are really building. If you are a parent, a teacher, or a mentor, this is about why the skills your child or student is developing matter far beyond the examination hall.
The First-Principles Habit
The most distinctive skill that the BPhO cultivates is the habit of first-principles thinking. In a BPhO problem, you are rarely told which formula to use. The question presents you with a physical situation — a charged particle in a magnetic field, a damped oscillator driven by a variable force, a heat engine operating between two reservoirs — and you must work out, from scratch, how to approach it. You identify the relevant principles. You set up the equations. You solve them, check your answer, and explain your reasoning clearly.
This is exactly the mental process that defines great entrepreneurs. When Elon Musk talks about building a rocket by reasoning from the cost of raw materials, rather than by analogy to existing rockets, he is doing first-principles thinking. When a startup founder asks, "What does this problem actually require? What is the simplest solution that works? What can we ignore?" they are doing the same thing that a BPhO student does when they open a paper and begin to work through a novel problem. The content is different — one is physics, the other is business — but the underlying cognitive architecture is identical.
The BPhO trains this habit deeply, because it has to. The problems are designed to be unsolvable by pattern-matching alone. You cannot look at a BPhO problem and say, "Oh, this is like the one I did last Tuesday." You have to look at it fresh, identify the relevant principles, and build the solution from the ground up. Over time, this becomes a default mode of thinking — a way of approaching any unfamiliar challenge that is grounded in reasoning rather than memory.
Comfort with the Unknown
One of the most valuable — and most underrated — things the BPhO teaches is comfort with uncertainty. Every BPhO student knows the feeling: you have read the problem three times, you have tried two different approaches, and neither has worked. You are not sure you even understand what the question is asking. In that moment, most people would feel anxious, inadequate, or defeated. The BPhO student learns to feel none of these things — or rather, to feel them and not be paralysed by them.
This is the emotional landscape of entrepreneurship. A founder spends most of their time in a state of not knowing — not knowing whether the product will work, not knowing whether customers will buy, not knowing whether the funding will come through. The founders who succeed are not the ones who avoid uncertainty; they are the ones who have learned to function within it, to make decisions with incomplete information, and to keep moving forward when the path is unclear. The BPhO is, in a quiet way, a training ground for this particular form of resilience.
What is more, the BPhO teaches that uncertainty is not the enemy of progress — it is the precondition for it. The most interesting problems are the ones you do not immediately know how to solve. The most important questions are the ones whose answers are not yet known. Learning to sit with uncertainty, to interrogate it rather than flee from it, is one of the most transferable skills a student can develop, and it applies as much to launching a startup as to solving a physics problem.
The Deep Tech Advantage
There is a category of startup where the BPhO background is not merely helpful but essential: deep tech. These are the companies that are building new things at the frontiers of engineering — robotics, semiconductors, quantum computing, fusion energy, advanced materials, aerospace, biotechnology. In these fields, the product is the physics, and you cannot fake the physics. You cannot outsource it to a consultant or hire it away from a competitor. You need to understand it yourself, at the level of the BPhO and beyond.
Consider the founder of a robotics company who needs to design a new actuator. The actuator must produce a specific torque, operate within a temperature range, and fit within a volume constraint. This is, at its heart, a physics problem — a problem involving electromagnetism, mechanics, and thermodynamics. The founder who can sit down and derive the relevant equations from first principles has an enormous advantage over the one who relies on rule-of-thumb or off-the-shelf solutions.
Or consider a startup working on battery technology for electric vehicles. The battery is an electrochemical system, and understanding its behaviour requires knowledge of thermodynamics, kinetics, and charge transport — all topics that the BPhO covers in depth. The founder who understands these principles can have informed conversations with their engineering team, can identify which technical claims are plausible and which are not, and can make better strategic decisions about where to invest their limited resources.
This is not a hypothetical argument. Some of the most successful deep-tech companies of the past decade have been founded by people with serious physics backgrounds — people who, in many cases, discovered their love of physics through olympiad competitions. The BPhO is one of the most important pipelines into this world, and the students who pass through it are, without necessarily realising it, preparing themselves for careers at the frontier of technological innovation.
Quantitative Intuition
Another skill that the BPhO cultivates, and that is extraordinarily valuable in business, is quantitative intuition — the ability to look at a situation and make a reasonably accurate estimate of the relevant quantities, without reaching for a calculator or a spreadsheet. In the BPhO, this is sometimes called "order-of-magnitude reasoning" or "Fermi estimation," and it appears explicitly in the short-answer questions of Round 1.
In business, this skill is invaluable. A founder who can look at a market and estimate its size within a factor of two — without spending three weeks on market research — has a significant advantage. A founder who can look at a technical proposal and say, "The energy budget doesn't work," or "The cost per unit is an order of magnitude too high," can save months of wasted effort. This kind of intuition is not innate — it is developed through practice, and the BPhO is one of the best places to develop it.
What makes this skill particularly powerful is that it is fast. In a board meeting or an investor pitch, there is no time to run a full analysis. The ability to make a quick, reasonably accurate judgment — to say, "That number feels too high" or "That timeline feels too optimistic" — and to explain why, is a skill that separates the best founders from the rest. And it is a skill that every BPhO student develops, week by week, problem by problem, as they learn to make sense of unfamiliar physical situations.
The Art of the Clear Explanation
There is a moment in every startup pitch where the founder must explain a complex technical idea to someone who does not have a physics degree — an investor, a customer, a journalist. The founders who succeed in this moment are not the ones who dumb down their explanation. They are the ones who have developed the habit of explaining clearly — who can take a complex idea and present it in a way that is both accurate and accessible.
This is precisely the skill that the BPhO rewards. In a BPhO answer, you do not get marks for simply writing down the correct equation. You get marks for explaining your reasoning — for showing why you chose a particular approach, how you set up the equations, and what each step means physically. Over years of practice, this becomes a deeply ingrained habit: the habit of thinking clearly and communicating clearly, even when the subject matter is complex.
For a founder, this skill is worth its weight in gold. The ability to stand before a room of investors and explain, in plain language, why a complex technology works and why it matters — without oversimplifying to the point of dishonesty — is one of the rarest and most valuable skills in the startup world. And it is a skill that the BPhO develops, quietly and consistently, in every student who takes the trouble to write up their solutions properly.
The Network Effect
Beyond the skills, there is another, less tangible benefit of the BPhO that is enormously valuable in the entrepreneurial world: the network. The students who participate in the BPhO — particularly those who reach the training camp and beyond — form a community of exceptionally talented and motivated individuals. These friendships and connections persist long after the competition itself is over, and they become a resource of incalculable value in the years that follow.
Many of the founders of deep-tech startups know each other. They met at an olympiad training camp, or at a university physics society, or at a conference that grew out of the BPhO community. When they need a co-founder, a technical advisor, or a first employee, they often turn to this network — and they find people who share their intellectual values, their work ethic, and their commitment to building things that matter. The BPhO, in other words, is not just a competition; it is the beginning of a professional community that lasts a lifetime.
A Broader Definition of Success
It is worth pausing here to acknowledge something important: not every BPhO student will become an entrepreneur, and not every entrepreneur needs a BPhO background. The point of this article is not to argue that the BPhO is a prerequisite for business success. It is to argue something more modest and, we think, more interesting: that the skills the BPhO develops — first-principles thinking, comfort with uncertainty, quantitative intuition, clear communication — are precisely the skills that are most valuable in the entrepreneurial world, and that students who develop these skills through the BPhO are, whether they realise it or not, preparing themselves for a much wider range of futures than they might imagine.
Some BPhO students will become academic physicists. Some will become engineers. Some will become teachers. Some will go into finance, or medicine, or law. And some — perhaps more than we currently realise — will become founders, building companies that solve problems we do not yet have names for, using technologies that do not yet exist. The BPhO will not have prepared them for any of these futures specifically. But it will have prepared them for the one thing they all have in common: the need to think clearly, act decisively, and build something from nothing.
What This Means for Students
If you are a student reading this, and you are in the middle of BPhO preparation, you may be wondering what any of this has to do with the differential equation you are currently stuck on. The answer is: everything, and nothing. You are not solving that equation to become an entrepreneur. You are solving it because you love physics, because the problem is interesting, because you want to understand how the world works. These are reasons enough, and they are the best reasons.
But it does no harm — and it may do a great deal of good — to keep in mind that the skills you are developing have a life beyond the exam. The habit of first-principles thinking will help you in whatever you choose to do with your life. The comfort with uncertainty will help you make decisions when the path is unclear. The quantitative intuition will help you evaluate ideas and proposals with speed and confidence. The habit of clear communication will help you explain your thinking to anyone, from a technical colleague to a non-technical investor to a curious friend.
These are not "soft skills." They are the hardest skills there are, and they are the ones that will define your ability to make an impact in the world. The BPhO is teaching them to you, one problem at a time.
What This Means for Parents and Teachers
If you are a parent or teacher, this article may change the way you think about what your child or student is doing when they sit down with a BPhO past paper. They are not just studying for a competition. They are developing a way of thinking that is, in the most literal sense, entrepreneurial — a way of thinking that involves identifying problems, building solutions from first principles, testing those solutions against reality, and communicating them clearly.
This is a way of thinking that the world needs more of — not just in physics, and not just in business, but in every domain where complex problems require clear minds and creative solutions. By supporting your child's BPhO journey — by giving them space to work, by showing interest in what they are doing, by resisting the temptation to make the outcome more important than the process — you are helping to develop a kind of mind that is rare, valuable, and capable of changing the world.
The Long View
There is a famous story about Richard Feynman, who was once asked by a journalist to explain a complex physics concept in simple terms. Feynman thought for a moment, and then said, "I can explain it to you, but I can't understand it for you." The journalist was confused, but Feynman was making a profound point: understanding is not something that can be transferred from one person to another. It must be built, from the inside, by the person who does the understanding.
This is what the BPhO is really about. It is not about transferring knowledge. It is about building understanding — slowly, patiently, one problem at a time. And the understanding it builds is not just about physics. It is about how to think, how to solve problems, how to communicate ideas, and how to persist in the face of difficulty. These are the skills that entrepreneurs need. They are also the skills that scientists, engineers, teachers, doctors, and leaders need. They are, in fact, the skills that any person needs who wants to make a meaningful contribution to the world.
The BPhO is teaching them to you, one equation at a time. And one day — perhaps in a boardroom, perhaps in a laboratory, perhaps in a classroom or a hospital or a factory — you will use them to build something that matters. And when you do, you will look back on the evenings you spent wrestling with a damped pendulum, and you will realise that the pendulum was never really the point. The point was always the mind that solved it.
