Fermi Questions: How to Measure the Immeasurable?
If you enjoy tackling complex and fascinating problems, you’ve probably heard of Fermi questions. This unique approach to thinking allows us to handle tasks that seem impossible to measure or comprehend at first glance. It’s an art of finding connections between seemingly unrelated objects and phenomena, making the thought process both captivating and effective. But how did these intriguing questions come about, and who brought them to life? It all began with the brilliant physicist and mathematician Enrico Fermi.
Enrico Fermi was an extraordinary scientist of his time, leaving an indelible mark on the history of science. Not only was he a talented physicist, but also a brilliant thinker who contributed to creating the first nuclear reactor in the U.S. and participating in many critical scientific projects. What set Fermi apart from other scientists was his unparalleled ability to find unexpected connections between various aspects of reality. He had a knack for “reading between the lines” and seeing what others missed. This very talent laid the foundation for the questions that now bear his name.
Fermi questions might seem challenging and even pointless at first, but they actually train your intuitive thinking and ability to establish logical connections. For example, one well-known Fermi problem asks, “How many cows are there in Canada?” To answer this, you would need to consider multiple factors: the population of the country, the area of arable land, average livestock statistics, and much more. Another example could be estimating the number of pianos tuned annually in Los Angeles. By assessing the number of people involved in music, the number of music schools, and the average workload of piano tuners, you can arrive at a reasonably accurate estimate.
By reading our blog post, you’ll dive into the fascinating world of Fermi questions and master the skills to tackle these challenges. Additionally, you’ll discover how to apply these principles in your everyday life. Fermi questions are all around us, and by learning to solve them, you’ll enhance your thinking and gain new tools to address even the most unconventional problems.
Measuring the Unattainable: Lessons from Enrico Fermi
Enrico Fermi was not just a brilliant theoretical nuclear physicist, he was also a master of measurement who could determine parameters that seemed unreachable to most of his contemporaries. His unconventional methods showcased not only his professional expertise but also his unique approaches, which he passed on to his students.
One of the most striking examples of Fermi’s talent was during the Trinity atomic bomb test in 1945. When the explosion occurred, many seasoned scientists were unsure how to measure its power accurately. However, Fermi, equipped with nothing more than a notepad and a pencil, devised a method to do so without high-tech instruments. He tore a sheet from his notebook into small pieces and let them fall in the direction of the wind, noting their positions after the blast. By measuring the distance and direction the paper pieces were displaced, he estimated the explosion’s force and concluded it exceeded 10 kilotons of TNT. The officially recorded yield was 18.6 kilotons, proving Fermi’s calculations were remarkably close and astounding many of his peers.
This example underscores the significance of precision and attention to detail. Even simple items like pieces of paper can become powerful tools for scientific discovery when used correctly. Such an approach doesn’t undermine, but rather enriches and complements the methodology of scientific research.
Another notable example from Fermi’s career involves his “Fermi problems”—hypothetical questions that require quick yet accurate estimation of quantities. For instance, he challenged his students to determine the number of piano tuners in Chicago using basic statistical data. In another instance, he asked them to estimate the number of water molecules in a glass of water that spilled into the Mississippi River and eventually ended up in New York City’s water supply. These academic exercises helped students develop Critical thinking and estimation skills that are essential not just for science but also for practical life.
These examples highlight that the ability to measure even the most complex things can be achieved by paying close attention to details and employing unconventional methods. Fermi’s tools and methodology prove useful beyond scientific work; they enhance our attentiveness and thoroughness in everyday life as well. Whether it’s using scraps of paper on a test range or posing hypothetical questions in a classroom, Fermi’s techniques inspire the search for simple solutions to complex problems, demonstrating that science is the art of the possible.
How to Find Out the Number of Cows in Canada in Just One Minute
Imagine you’re suddenly asked how many cows live in Canada. At first glance, this might seem like a daunting question, but there’s actually a method that can get you the answer in just 60 seconds. The key lies in using critical data and basic logical reasoning.

The first step in solving this problem is to gather essential facts. For instance, start with the population of Canada. There’s a direct relationship between the number of residents and the volume of dairy products consumed. Let’s assume the population of Canada is around 38 million people. Next, estimate the average dairy consumption per person. The average Canadian consumes about 80 liters of milk annually.
Then, calculate how much milk one cow can produce. On average, a single cow produces around 8,000 liters of milk each year. By multiplying 38 million by 80 liters, you get approximately 3,040 million liters of milk consumed in Canada annually. Now, divide this figure by the milk production of one cow, and you’ll get a rough estimate of the number of cows required—around 380,000.
Of course, this approach has its limitations and doesn’t account for all factors. For example, some milk might be exported to other countries, and some cows are raised exclusively for meat. Even though these details aren’t included, the estimated number gives a good sense of the scale of dairy production.
A similar method can be applied to estimate the number of cars in a city. Suppose you know the population of a city and the average number of cars per household (say, 1 car for every 2 families). By comparing these data, you can also approximate the number of cars.
The key to solving such problems is learning to simplify and optimize calculations. If you have enough data and a systematic method to process it, you can quickly derive useful information.
Puzzles at Work: How Companies Use Them and Why You Should Learn to Solve These Challenges
Puzzles are more than just an entertaining pastime or a way to kill some free time. They serve as a powerful tool for mental training and the development of cognitive skills. Nowadays, many companies and universities actively incorporate puzzles into their employee selection and training programs. This approach allows them to evaluate not just academic knowledge, but also creativity and the ability to think outside the box.
It’s widely believed that puzzle-related tasks help employers and educators understand how candidates or students think. For instance, during interviews, Google might present a challenging riddle or logic problem. This practice helps identify candidates who can effectively tackle unconventional tasks, showcasing their innovation and problem-solving abilities.
A famous example is the three switches and lamp puzzle: “You have three switches in front of you. One of them controls a lamp in the adjacent room, while the other two are not connected. How can you determine which switch controls the lamp without entering the room and only flipping the switches once?” The answer, rooted in analytical thinking, illustrates the importance of logical step-by-step reasoning and evaluating the consequences of your actions.
Successfully solving such puzzles requires the ability to find connections between different elements of the problem and skillfully apply your knowledge in new contexts. For example, the river-crossing puzzle involving a wolf, a goat, and a cabbage teaches strategic planning and multi-option approaches to achieve a goal. This skill is particularly important in the workplace, where many tasks demand not just a single correct solution, but the ability to choose optimal paths to reach the desired outcome.
Moreover, the correct answer isn’t always the most important part of solving a puzzle. Employers and educators often value an applicant’s thought process, how you approach breaking down a problem, and the strategies you use. This insight allows them to assess your potential for growth, adaptability, and ability to prioritize. Tackling challenging tasks demonstrates your readiness for tough situations and your capacity to find solutions even in the most tangled scenarios.
In this way, puzzles can open new doors, offering unique opportunities to showcase your intellectual capabilities and potential to employers or in an academic setting.
