Is atomic theory the most important idea in human history?

Quantum phenomena is definitely complex but idk if it's the most important idea. Human consciousness seems more interesting. Is consciousness related to quantum phenomena or can be measured on that level at all?
- erikpukinskis 10y ago
  I think it's about as important now as the clockwork was in the 19th, or the computer was in the 20th century. We make these fundamental discoveries about how the world works, and then there is a period where that metaphor is used to gain subatantially new understandings in every field. We are just starting to absorb quantum ideas: non-causality, waveform collapse, etc. We'll spend the next decades seeing how those ideas can change our understanding of all kinds of things. Then the metaphor will go in our knapsack with all the others. In that sense you are both right. He's right that the quantum metaphors are very important right now. You're right that they are just some of many. You're probably more right than he is though. Most important "of all time" is almost certainly wrong.

  > Human consciousness seems more interesting. Yes, true, but what would be say about it? We still have no idea how it works. So in a sense, it's not an idea yet, it's an observation.

I vote for the special and the general theory of relativity.
- raattgift 10y ago
  > I vote for the special and the general theory of relativity. Out of curiosity, why? I can think of several possible reasons, but I'd like to know yours. FWIW, I'm inclined to agree with Rovelli about atomism when "atoms" in the most general sense of the smallest particles are like-for-like substitutable. Following from that, the two theories of relativity set conditions on when "like-for-like substitution" is exact and when it's approximate. In other words, I think that atomism is more reductive than SR or GR even in their modern formulations, and reductive materialism is a crucial tool in a scientist's mental toolbox. (One could also snarkily say that atoms and subatomic particles are the "material" without which SR and GR are effectively useless and even justify that via the hole argument.)

"If, in some cataclysm, all of scientific knowledge were to be destroyed, and only one sentence passed on to the next generations of creatures, what statement would contain the most information in the fewest words? I believe it is the atomic hypothesis (or the atomic fact, or whatever you wish to call it) that all things are made of atoms—little particles that move around in perpetual motion, attracting each other when they are a little distance apart, but repelling upon being squeezed into one another. In that one sentence, you will see, there is an enormous amount of information about the world, if just a little imagination and thinking are applied." - RP Feynman, Vol I FLP
- runeks 10y ago
  I think it may be more important to tell them about bacteria. But in reality, I think passing down a single sentence is almost completely useless. If that's all that's passed down, they will have to make the exact same discoveries we made, although we may be able to lead them towards these discoveries. Also, expecting all of future human kind -- more developed than we are now -- to value some sentence passed down by their oh-so-knowledgeable ancestors (us) seems a bit self-centered to me. A more intelligent future mankind will make their own discoveries, and not care much about any single sentence, regardless of who wrote it.

  David Graeber does a good job of debunking the theory of currency as a replacement for barter in his book _Debt_ (if that's what you're getting at with the ordering).
  - tabeth 10y ago
    I completely agree. I personally believe barter is implicit in property ownership. Since you can't barter anything you don't own, and once you do own something bartering (in my opinion) is inevitable.
- kahrkunne 10y ago
  I think property ownership is an instinctive trait. Just like you don't have to tell a cat to piss against all the trees to assert ownership, you probably don't need to tell people about property. I guess we could tell them "communism is bad" but that's a bit too cold war even for me.
  - tabeth 10y ago
    Is property ownership instinctive? I'd definitely agree that [usage] is instinctive, in that one may want to use something without interruption or threat of having it taken away during usage. However, the idea that one needs to own something after it has been used, no longer needs to be used, or simply is no longer in use seems interesting. Maybe I'm too idealistic, but I could imagine a society where everything is communal. I just think we started off in a way that would make it too difficult to transition to that now (too many people have too much to lose).

Microorganisms as a source of disease seems a pretty important concept; we take it for granted now, but ignorance of this was a huge deal up until about 150 years ago.
- igravious 10y ago
  I think you're right. I think that _is_ a more important concept. Why? Because it does many things at once. 1) Establishes natural biological causes for the transmission of diseases, thereby supplanting all sorts of other theories like hex-casting, bad omens, malevolent deities, and so on and so on 2) It says that there are things that can't be seen with the naked eye that share our biology, which opens the door to atomism anyway 3) It says that biology shares a common substrate which is a useful concept in itself 4) And practically speaking, if the information that microorganisms are disease vectors is coupled with the knowledge that certain routines such as cleaning and washing prevent said transmission and that other substances act as anti-bacterial agents then human and animal welfare is promoted and suffering is reduced allowing for more rapid societal progress Therefore, I agree with you.
- yabatopia 10y ago
  Especially vaccines. It's such a counterintuitive concept : injecting yourself with a small doses of a disease to prevent that disease. Do you want some polio, it's good for you? Er, no, go away you freak! Contrast that with atomic theory: nearly everybody can grasp the concept that bigger parts are made of smaller parts.
- woodandsteel 10y ago
  That is a very important idea, but it was atomism that lead to it. For thousands of years, people explained natural phenomena like disease through alleged supernatural causes. Then Greek science-philosophers attempted to explain them through thoroughly natural causes. They tried various ideas like everything is fire, but it was atomism that was successful, and it lead to modern science in general.
lutusp 10y ago
Given the presumed goal to convey as much as possible in as few words as possible, to me it's a tie between atomic theory and evolution. Maybe we could cram both into a carefully worded sentence.

No. It's the scientific method - by which truth can be separated from crap. https://en.wikipedia.org/wiki/Scientific_method https://en.wikipedia.org/wiki/Scientific_method
- vog 10y ago
  Indeed! This principle enables a civilization to discover all important things they need, on their own, in a reasonable speed. Having said that, I see two areas in science where we have serious issues. 1) In some sciences, strict application of scientific method is not possible in large scale, due to unhealthy influence from the outside. The classic example from the middle age is the research on astronomy and physics being suppressed and/or heavily influenced by the church and political leaders. Today, one of the best examples is research on economy. That is heavily influenced (and sometimes even paid) by various types of financially strong bodies. This leads to heavily biased results. Also, suddenly results become acceptable even though they are based on almost comically far-fetched assumptions. 2) In some sciences, the scientific method cannot be applied in all rigor, due to the nature of the topic of research. For example, complex psychological tests cannot be done with a huge amount of people, because you won't find enough people doing so volutarily. Also, you can't simply repeat an experiment on the same human being, because are are influenced from and learned from the previous experiment, so will react differently than an "unused" human being.
  - hueving 10y ago
    Economics falls under the second category quite a bit as well. In particular its hard to reason about impacts of individual policies on any kind of real complex economy because there are so many confounding variables. And it's not like you can conduct experiments because time travel isn't possible and no two economies are even similar, let alone the same.
    - vog 10y ago
      I agree that the empirical part of economics is hard, but manageable in modern times [1]. However, the real problem is that even the theory has so many flaws, yet it is used as if it was evidence, which is why I think the real problem is 1). [1] Some very popular multi-player games have a quite advanced economy, where the individual actions of each participant are recorded and can be analyzed. While this is not "real", it gives more detailed information about human economic interaction than all the mass surveillance in the "real word" right now. Also, the game developers have god-like powers in the virtual world, so they can run controlled experiments,. As far as I know, they already do so. And and if something goes really wrong, they still have the ultima ratio to reset everything to the state of a few hours or days ago. Or, they can re-interpret the last actions of the players in a more appropriate way. That may still make some players unhappy, but won't crash a real economy.
unknown_apostle 10y ago
For all the greatness of Democrites in so many ways, I'm always a bit wary of reading too much in classic thinkers predating what we now know about the physical sciences. Without experiments, introducing the concept of atoms was speculative. Conversely, even today an improved understanding of how matter actually behaves at very small scales, still doesn't make the case for atheism or materialism.
austinl 10y ago
I just read two books that I thought would be unrelated, but ended up being very related in a way that was fascinating to read the two in tandem — The Swerve by Stephen Greenblatt, and The Making of the Atomic Bomb by Richard Rhodes. The Swerve is about Epicurus and Lucretius — who both helped popularize atomism 2000+ years ago. I never thought much of the philosophical implications of the world being made of up small, somewhat interchangeable parts — but this idea was at the core of Epicureanism, and had many implications. If you're interested in learning more about the history of atomic theory, I'd highly recommend The Making of the Atomic Bomb. It goes through the general history of science from the 1890s to the 1950s. There are brief biographies of people who played an important role — Ernest Rutherford, Enrico Fermi, Niels Bohr, and Albert Einstein (to name a few). Those were exciting times to be a physicist. https://www.goodreads.com/book/show/13707734-the-swerve https://www.goodreads.com/book/show/13707734-the-swerve https://www.goodreads.com/book/show/16884.The_Making_of_the_Atomic_Bomb https://www.goodreads.com/book/show/16884.The_Making_of_the_...
- Retric 10y ago
  Atomism assumes unchanging building blocks which antimatter disproves. Which is really the problem when trying to link philosophical ideas with physics the real world is very odd and nobody actually came close. Even just from a chemistry standpoint atoms don't fit atomism unless you treat electrons and the nucleus as separate things. The name was copied before we really understood what was going on.

  - soundwave106 10y ago
    Instead of focusing on the toilet itself (whatever type one might use), I would focus more on overall sanitation systems and clean water. Yes, it is true that a billion people (more actually) do not have access to clean water or safe disposal of human waste. From my standpoint, this honestly is a huge deal -- clean water and proper sanitation would most likely improve health in many areas of the world tremendously. (In a way, this does tie in with the micro-organism disease theory mentioned by another poster above. When it comes to "most important ideas in human history", in terms of human lives saved, this has to be one of the top ones.)
- babyrainbow 10y ago
  Speaking of Toilets, I think all European closets can burn in hell. Please give me back my Indian closet. Why o Why did this abomination of an idea that is the european closet become so popular? Is it just out of a need to feel "civilized" by sitting instead of squatting, while taking a shit?

> Is atomic theory the most important idea in human history? One might ask if the theory is a correct one though. If you look for something hard enough, chances are you will find it. Perhaps a more realistic model for the universe is as a continuous blob of stuff, with some more condensed clumps that we now call atoms.
losteverything 10y ago
To answer the question: not sure. Given: an "idea" is stateless. It's any expressed human thought. Thus, I would say "faith" is the single idea. E.g. faith in afterlife.
johndoe4589 10y ago
> That the world is not solid but made up of tiny particles I'm not sure that's how most people understand it. "Tiny particles" still maintains the notion for most of us of a physical / materialist world when things truly exist, with some kind of an inner essence or structure or core, which we would associate to these "particles". Se we think that a tree, or a car, is a bunch of those particles. And that we too are a bunch of particles. It doesn't shake the notion of physical existence so it has no profound impact on the way we see ourselves and the world and the way we behave. It's very hard to let go of this view though. A very healthy and middle step that I wish was taught everywhere is to start looking at the world as an interdependent system, including us, and understand nothing truly exists in isolation.
rahelzer 10y ago
The general principle that any problem you face, no matter how big, can be broken down into smaller and easier to solve problems, recursively, is the most important idea in human history. Atomic theory is just a special case of this insight.

    What is it?
- Slackwise 10y ago
  More succinctly, this is Reductionism: https://en.wikipedia.org/wiki/Reductionism#Theory_reductionism https://en.wikipedia.org/wiki/Reductionism#Theory_reductioni...
  - rahelzer 10y ago
    There is a subtle difference between this and reductionism. Suppose your big problem is you are hungry. You could break this big problem into little problems in many different ways, e.g. [drive to McDonalds, get food], or [go to fridge, eat leftovers], etc. Either way, you have solved your original problem, but you haven't reduced your original problem. Your original problem was not that you had to go to Mcdonalds, nor was it that you had to got o the fridge. Your original problem was that you were hungry, which is distinct from the solutions.
- drtillberg 10y ago
  What is special about atomic theory is the supposition that there is an endpoint to recursive reduction. That at some point you cannot find anything simpler.

Beyond animal instincts I would put language, money and the atmoic theory as most important in that order.
hutzlibu 10y ago
" Atoms are indivisible; they are the elementary grains of reality, which cannot be further subdivided, and everything is made of them" Well, it would be ironic, if human kind wipes itself out in a nuclear holocaust (which means dividing too much "undividable" atoms) and future life finds about our fate and our "most important idea"... I would vote for Relativism instead.
pklausler 10y ago
More important, I think, is the concept of objective, empirical, peer-reviewed science. Democritus made up the concept of atoms, but it took 2,000 years before science made them real in Einstein's paper on the Brownian motion.
raattgift 10y ago
Durable information storage. Mass distribution of information. Universal literacy. Too little of what was written in antiquity was accessible to the vast majority of people, and too much of it was lost. We're left with fragments of early mathematical, literary, and historical works and our attempts to figure out what ordinary people were up to are almost stuck with just graffiti on the few hard surfaces that have survived.

bobthechef 10y ago
What an awful article, elementary school quality stuff drawn from mediocre school texts. It is littered with historical inaccuracies, caricatures of philosophical positions, and maudlin sentiments and hagiographic bromides that contradict the very atomism that it celebrates (such at the addled paeans to Epicurus or delusional hymns to some incoherent New Age-y "unity"). Democritus himself was not blind to at least a couple of the problems with his atomism. Why is there no mention of his own objections or the objections of others? Furthermore, materialism and rationalism are a highly problematic positions with serious objections against them. Quoting philosophical ignoramuses (and that's putting it nicely) is doing this author no favors. Atomism is NOT the most important idea in history. Try getting a real education, dear author. You make a mockery of yourself.

According to R. Feynman - yes.

> Is atomic theory the most important idea in human history? One might ask if the theory is a correct one though. If you look for something hard enough, chances are you will find it. Perhaps a more realistic model for the universe is as a continuous blob of stuff, with some more condensed clumps that we now call atoms.

To answer the question: not sure. Given: an "idea" is stateless. It's any expressed human thought. Thus, I would say "faith" is the single idea. E.g. faith in afterlife.

> That the world is not solid but made up of tiny particles I'm not sure that's how most people understand it. "Tiny particles" still maintains the notion for most of us of a physical / materialist world when things truly exist, with some kind of an inner essence or structure or core, which we would associate to these "particles". Se we think that a tree, or a car, is a bunch of those particles. And that we too are a bunch of particles. It doesn't shake the notion of physical existence so it has no profound impact on the way we see ourselves and the world and the way we behave. It's very hard to let go of this view though. A very healthy and middle step that I wish was taught everywhere is to start looking at the world as an interdependent system, including us, and understand nothing truly exists in isolation.

The general principle that any problem you face, no matter how big, can be broken down into smaller and easier to solve problems, recursively, is the most important idea in human history. Atomic theory is just a special case of this insight.

More succinctly, this is Reductionism: https://en.wikipedia.org/wiki/Reductionism#Theory_reductionism https://en.wikipedia.org/wiki/Reductionism#Theory_reductioni...

  There is a subtle difference between this and reductionism. Suppose your big problem is you are hungry. You could break this big problem into little problems in many different ways, e.g. [drive to McDonalds, get food], or [go to fridge, eat leftovers], etc. Either way, you have solved your original problem, but you haven't reduced your original problem. Your original problem was not that you had to go to Mcdonalds, nor was it that you had to got o the fridge. Your original problem was that you were hungry, which is distinct from the solutions.

What is special about atomic theory is the supposition that there is an endpoint to recursive reduction. That at some point you cannot find anything simpler.

If the human race ends in nuclear holocaust, then yes, it was.

Beyond animal instincts I would put language, money and the atmoic theory as most important in that order.

" Atoms are indivisible; they are the elementary grains of reality, which cannot be further subdivided, and everything is made of them" Well, it would be ironic, if human kind wipes itself out in a nuclear holocaust (which means dividing too much "undividable" atoms) and future life finds about our fate and our "most important idea"... I would vote for Relativism instead.

More important, I think, is the concept of objective, empirical, peer-reviewed science. Democritus made up the concept of atoms, but it took 2,000 years before science made them real in Einstein's paper on the Brownian motion.

Durable information storage. Mass distribution of information. Universal literacy. Too little of what was written in antiquity was accessible to the vast majority of people, and too much of it was lost. We're left with fragments of early mathematical, literary, and historical works and our attempts to figure out what ordinary people were up to are almost stuck with just graffiti on the few hard surfaces that have survived.

No, it is antibiotics and the germ theory of disease. If it weren't for them, we wouldn't be here to ask the question.

What an awful article, elementary school quality stuff drawn from mediocre school texts. It is littered with historical inaccuracies, caricatures of philosophical positions, and maudlin sentiments and hagiographic bromides that contradict the very atomism that it celebrates (such at the addled paeans to Epicurus or delusional hymns to some incoherent New Age-y "unity"). Democritus himself was not blind to at least a couple of the problems with his atomism. Why is there no mention of his own objections or the objections of others? Furthermore, materialism and rationalism are a highly problematic positions with serious objections against them. Quoting philosophical ignoramuses (and that's putting it nicely) is doing this author no favors. Atomism is NOT the most important idea in history. Try getting a real education, dear author. You make a mockery of yourself.
