This article explores fascinating questions about bees' computational abilities, the concept of universal Turing machines, the influence of language on facial features, and a new calendar system that redefines human history. It also delves into consciousness, the nature of computation in living beings, and perspectives on time and life through innovative visualizations.
In this comprehensive exploration, we delve into intriguing questions about the computational abilities of bees, the theoretical foundations of universal Turing machines, the impact of language and accents on facial features, and a novel calendar system that redefines how we perceive human history. Along the way, we touch on profound philosophical questions about consciousness and the nature of computation in living beings.
A viewer named Brian posed a fascinating question: since honeybees can recognize shapes, colors, odors, and landmarks, and can follow instructions and perform calculations based on input, could they be trained to simulate a universal Turing machine?
Research from 2019 in Australia demonstrated that bees can be taught to add and subtract using a Y-shaped maze and sugar water rewards. Bees were trained to associate colors with addition or subtraction. For example, if the shapes were blue, the bee had to add one; if yellow, subtract one. The bee would then choose the correct path in the maze based on this rule, reliably performing the task.
This shows bees can count and follow instructions based on color cues, which is remarkable given their small brains.
Bees also communicate through the waggle dance, which conveys the direction and distance to pollen sources relative to the sun. Experiments showed that if a bee's vision of the sun was altered, it would miscommunicate directions, leading other bees astray. This highlights the complexity of bee communication despite their limited neural resources.
A universal Turing machine is a theoretical computer proposed by Alan Turing before modern computers existed. It uses an infinite tape divided into squares, reads and writes symbols, and moves left or right based on rules. Given enough time and tape, it can solve any computable mathematical problem.
While bees can follow rules and move through systems, they cannot write or place symbols on the tape, which is essential for a universal Turing machine. Therefore, bees cannot simulate a universal Turing machine.
In 2011, researchers from Japanese and English universities experimented with soldier crabs, which move in swarms and combine like soft billiard balls when colliding. They built logic gates (AND, NOT, OR) using crab swarms in mazes, demonstrating that crabs could perform basic computational logic.
Though no single crab understands the computation, collectively they can simulate logic gates. Scaling this up to a full computer would require billions of crabs, making it impractical but conceptually fascinating.
The discussion raises profound questions: are human brains approximate Turing machines? Is consciousness an emergent property of complex computation, or is there something beyond computation?
One perspective is that consciousness might not be purely emergent but could be a fundamental property of the universe, akin to electromagnetism or gravity, a view related to panpsychism.
Another viewer, Gavalotas, asked whether languages and accents influence facial features through the muscles used in speech, giving people subtle but unique characteristics.
Speaking different languages involves using lips, cheeks, tongue, and jaw differently. For example, tonal languages affect facial muscle movement noticeably.
A notable case is the South African language !Xóõ, which has many click consonants. A linguist named Anthony Traill, who learned !Xóõ, developed a bump on his larynx similar to native speakers, suggesting that prolonged use of certain speech sounds can physically alter musculature.
Some speech sounds, like labiodental sounds (e.g., "v" and "f"), may have emerged only after humans began eating softer foods. Tribal cultures with harder diets often have different dental structures, which could influence the ease of producing certain sounds.
While some believe language influences facial musculature, most researchers attribute facial differences across generations primarily to grooming styles and diet rather than language alone.
An interesting cultural observation is that actors or people from different eras have faces that seem to reflect their time, sometimes described as having an "iPhone face" or a face from a past generation.
A game involves guessing whether lips touch when pronouncing certain words. For example, lips do not touch when saying "touch" but do when saying "separate." This highlights how little attention we pay to the physicality of speech.
Listener Michael Ror created the Holocene calendar, which starts at zero at the beginning of the Holocene era, about 12,000 years ago, marking the end of the last ice age and the start of significant human development.
For example, the current year 2026 AD is 12,026 in the Holocene calendar.
Michael Ror developed a website visualizing the Holocene era with notable events in politics, science, and culture, allowing users to see the relative timing of events more intuitively.
This visualization highlights the exponential acceleration of technological and cultural progress, with long periods of little change followed by rapid developments in recent millennia.
The book "If" offers mind-bending visualizations of big ideas like time and population.

This visualization helps put our daily activities and finite time into perspective.
This exploration reveals the surprising computational abilities of bees and crabs, the foundational concepts of universal Turing machines, and the philosophical questions about consciousness and computation. It also sheds light on how language might subtly shape our physical features and introduces a new calendar system that reframes human history.
Understanding these concepts enriches our appreciation of life, time, and the intricate connections between biology, language, and technology.
