Discussion Overview
The discussion revolves around the perception of atoms and related visual phenomena. Participants explore the nature of what one might see when claiming to observe atoms in the air, addressing concepts from physics and biology, including visual perception and microscopy.
Discussion Character
- Exploratory
- Conceptual clarification
- Debate/contested
Main Points Raised
- One participant expresses a belief that they can see atoms in the air, prompting questions about the nature of this perception.
- Another participant asserts that atoms are too small to be seen with the naked eye and suggests that what is seen might be related to floaters in the eye.
- There is a discussion about the limitations of light microscopes, with one participant noting that individual atoms cannot be resolved due to their size compared to the resolution limits of such microscopes.
- Some participants mention alternative microscopy techniques that can resolve atoms, indicating a distinction between visible light microscopy and other methods.
- A participant introduces the concept of the blue field entoptic phenomenon as a possible explanation for the visual experience described.
- There is a sentiment expressed about the accessibility of learning science, emphasizing that curiosity is a key factor in understanding scientific concepts.
Areas of Agreement / Disagreement
Participants generally agree that atoms cannot be seen with the naked eye and that the visual phenomena described may have alternative explanations. However, there is no consensus on what exactly is being perceived or how to "unsee" it.
Contextual Notes
Participants reference various phenomena and concepts without resolving the underlying assumptions about visual perception and the nature of atoms. The discussion includes a mix of personal experiences and scientific explanations that may not fully align.
Who May Find This Useful
Individuals interested in visual perception, microscopy, or those beginning to explore scientific concepts related to physics and biology may find this discussion relevant.
individual atoms are too small to discern with a light microscope (that is one using visible light) as the resolution of such microscopes is on the order of ~100 nanometres. Atoms are around one thousand times smaller than this! However we can resolve atoms using microscopes that do not rely on photons; http://en.wikipedia.org/wiki/Scanning_tunneling_microscope" all have far greater resolution.
