    Things We Believed Before the Scientific Method

    enNovember 07, 2023

    Podcast Summary

    • New technology for diabetes management: Real-time glucose readingsThe Dexcom G7 system offers real-time glucose readings on compatible devices, enabling informed decisions about food, exercise, and medication without frequent finger sticks, potentially leading to improved diabetes management.

      Advancements in technology, like the new Dexcom G7 Continuous Glucose Monitoring system, are making it easier for people with diabetes to manage their condition more effectively. With real-time glucose readings on compatible watches and phones, users can make informed decisions about food, exercise, and medication without the need for frequent finger sticks. Additionally, the accuracy of the Dexcom G7 system provides confidence in these decisions, potentially leading to improved results such as more time in range and lower A1C levels. On the other hand, relying on pre-scientific methods for understanding the world can lead to incorrect theories and beliefs that persist for thousands of years. The scientific method, which involves forming a hypothesis, testing it, and analyzing results, allows for more reliable and consistent findings. For instance, the theory of the four humors, which was used for medical practices from the fourth or fifth century BCE until the 1600s, was based on philosophical thoughts rather than scientific testing. This underscores the importance of testing hypotheses and theories through scientific methods to ensure accurate and reliable knowledge.

    • The ancient Greeks' theory of humors and their impact on medicineThe ancient Greeks believed in the theory of humors, which influenced ancient medicine and Ayurveda, despite not being scientifically accurate. This belief persisted for centuries until the discovery of the circulatory system.

      The ancient Greeks believed in the theory of humors, which were considered as the fluids, energy, and other elements in the body. These humors - blood, black bile, and yellow bile - were not just physical substances but also represented different energies or temperaments. Each humor had a temperature and moisture level, and an imbalance of these humors led to diseases. The treatment involved using the opposite humor to restore balance. Although this theory was not scientifically accurate, it had a significant impact on ancient medicine and influenced the development of Ayurvedic medicine in India. The persistence of this belief for hundreds of years demonstrates the power of a consistent idea, even if it is not proven. The discovery of the circulatory system by William Harvey in the 17th century marked the end of humoral medicine's dominance.

    • Ancient Greek philosophers' contributions to early cosmological theoriesAncient Greek philosophers, like Eudoxus, proposed geocentric theories with celestial spheres, contributing to the foundation of modern astronomical discoveries, despite their complex and flawed models.

      Ancient Greek philosophers, such as Eudoxus of Cnidus, contributed significantly to the development of early cosmological theories, including the belief in a geocentric universe and the concept of celestial spheres. Eudoxus, born around 395-390 BCE, proposed a fivefold model, including the Earth as the center of the universe, circular and regular celestial motion, and the center of celestial motion being the center of the universe. Although geocentrism was later disproven, it was a reasonable belief at the time due to observable celestial movements and the human-centric worldview. Eudoxus also introduced the idea of celestial spheres, which he believed were responsible for the apparent motion of stars and planets. He proposed 27 spheres, some with smaller spheres within them, to explain various celestial phenomena. However, this complex model led to adding more spheres rather than reconsidering the theory, ultimately contributing to its eventual demise. Despite its flaws, the work of ancient Greek philosophers laid the foundation for modern astronomical discoveries.

    • Ancient beliefs shaped by limited tools and knowledgeScience is a continuous process of building upon previous knowledge, even seemingly incorrect theories can lead to new discoveries

      The ancient understanding of the universe was shaped by the limited tools and knowledge available to them at the time. For instance, the belief in circular orbits was largely due to the mathematical concepts and observations that were prevalent during that era. However, this belief was later debunked when more advanced tools and knowledge emerged, leading to the discovery of elliptical orbits. It's important to remember that our ancestors were not "dumb" for believing in circular orbits or other theories that seem wacky to us now. Instead, they were making the best guesses they could with the information they had. Science is a continuous process of building upon previous knowledge, and even seemingly incorrect theories can lead to new discoveries. So, the next time you look back at the history of scientific understanding with a smirk, remember that we were all trying to make sense of the world with the tools and knowledge we had at the time.

    • Ancient belief about Earth's revolving orbits around a central fireThe Pythagoreans, an ancient civilization, proposed a belief that all celestial bodies revolved around a central fire, foreshadowing later theories about the cosmos. Modern businesses, like Squarespace, offer accessible and convenient solutions for entrepreneurs to create professional online stores.

      The ancient Pythagoreans had an intriguing belief about the cosmos, which held that everything, including the Earth, revolved around a central fire. This belief, which came before both geocentrism and heliocentrism, proposed that the Earth, sun, moon, planets, and stars all had their circular orbits around this unseen fire. The Pythagoreans, including philosopher-scientist Croton, believed in the perfection of the number 10 and thus posited 10 orbits in total, including that of a counter-earth. Although their understanding of the cosmos was inaccurate, it showcases their early attempts to make sense of the observed data of the planets' varying orbital periods.

    • Ancient Elemental Models and the Concept of a Counter-EarthAncient philosophers proposed various elemental models, including Earth, Air, Fire, and Water. The idea of a counter-earth was later proposed but found to be inconsistent with observations.

      The concept of elements, including the idea of a counter-earth, has evolved throughout history based on scientific discoveries and theories. Ancient philosophers, such as Anaximenes and Aristotle, proposed various elemental models, with Earth, Air, Fire, and Water being the most well-known. These ideas were influenced by observations of the natural world and the belief that everything was made up of a single substance. However, later discoveries and models, such as the existence of a counter-earth, were found to be impossible or inconsistent with observations. The idea of elements continues to evolve as new scientific discoveries are made.

    • Ancient Greek philosophers Empedocles and Democritus proposed theories on elements and atomsAncient Greek philosophers Empedocles and Democritus were among the first to propose theories on the fundamental structure of matter, with Empedocles suggesting four basic elements and Democritus introducing the concept of atoms as indivisible units of matter in a vacuum

      Ancient Greek philosopher Empedocles was among the first to propose the idea that all matter is made up of small, indivisible units, which he called elements. He believed that there were four basic elements: earth, air, fire, and water. However, it was later philosopher Democritus who is credited with developing the atomic theory, suggesting that matter is made up of tiny, indestructible and eternal units called atoms. These atoms exist in free space, what we now call a vacuum. Democritus' atomic theory, though not without its flaws, was a significant step towards the scientific understanding of matter that we have today. Despite being proposed thousands of years ago, it is considered one of the best guesses in antiquity.

    • Ancient philosophers' conflicting views on matter and Toricelli's vacuum experimentAristotle believed in four elements, rejected atoms; Toricelli's experiment created a vacuum, proving atoms' existence; Dalton later presented atomic theory

      The ancient philosophers Aristotle and Plato had different views on the nature of matter. While Aristotle accepted the idea of four basic elements, he rejected Democritus' atomic theory due to his belief in the absence of a vacuum. However, it wasn't until 1643 when Evangelista Toricelli created the first vacuum in an experiment that the atomic theory gained traction. Toricelli's discovery showed that even though air is invisible and intangible, it has weight, proving Democritus' prediction that everything is made up of atoms. This breakthrough led to the investigation of atomic theory, which was eventually put forth by John Dalton in 1803. It's fascinating how close Aristotle came to understanding the atomic structure of matter, despite having no way to test his theories. Today, we have technologies like the vacuum and the microscope, which allow us to explore the microscopic world and confirm the atomic theory.

    • The Prevalence of Spontaneous Generation Beliefs Before the MicroscopeBefore the microscope, many believed in spontaneous generation of life from non-living matter. Ancient theories and specific beliefs persisted despite sounding absurd today, but the microscope's discovery revealed a new world teeming with life, eventually leading to its refutation.

      The belief in spontaneous generation, the idea that life could arise from non-living matter, was prevalent before the invention of the microscope. From ancient theories proposing the generation of mice from grains or scorpions from bricks, to more specific beliefs like maggots arising from rotting meat, these ideas were widely held despite sounding absurd to us today. However, the introduction of the microscope by Antoine van Leeuwenhoek challenged these beliefs by revealing a previously invisible world teeming with life. While the microscope did not immediately disprove the theory of spontaneous generation, it did provide a new perspective that eventually led to its refutation. Overall, the history of spontaneous generation demonstrates the importance of scientific inquiry and the power of observation in challenging long-held beliefs.

    • The Debate Between Spontaneous Generation and EpigenesisAristotle's epigenesis theory prevailed over spontaneous generation, but experiments eventually proved that life only arises from other living organisms.

      The debate between spontaneous generation and epigenesis shaped early scientific understandings of life's origins. Spontaneous generation, the belief that life could arise from non-living matter, was challenged by the scientific community through experiments. However, some believed that spontaneous generation could still occur in certain circumstances, such as the formation of maggots from decaying matter. Epigenesis, the theory that life arises from pre-existing life, was proposed by Aristotle and gained favor as the more accepted explanation. The two theories could even coexist, as spontaneous generation could lead to the start of life, which would then reproduce biologically. The scientific method eventually put an end to the debate, with Louis Pasteur's work demonstrating that life only arises from other living organisms. The ancient world saw the rise and fall of these theories, with Aristotle's epigenesis coming out on top. This discussion also touched upon the importance of scientific experiments and the role of skepticism in advancing scientific knowledge.
