Hey, Vsauce. Michael here. Where are your fingers? Seriously. It's a pretty easy question. You should be able to answer it. But how do you know? How does anyone know anything? You might say, well, I know where my fingers are. I'm looking right at them. Or, I can touch them, I can feel them, they're right here and that's good. Your senses are a grea... Read More

Questions & Answers

Q: What is proprioception and how does it work?

Proprioception, also known as kinesthetic sense, allows us to perceive the position and movement of our body parts in relation to each other. It enables us to know where our fingers, arms, head, and legs are without having to look or touch them.

Q: How do optical illusions deceive our senses?

Optical illusions trick our brains into perceiving something that is not actually there. They exploit the way our brains process visual information, causing us to see things differently from reality.

Q: Where are memories stored in the brain?

Memories are not stored in a single location in the brain. Instead, they are made up of complex relationships between different brain cells, forming a network of connections.

Q: Can we prove the existence of an objective reality?

No, it is impossible to prove the existence of an objective reality beyond our own perception. Our knowledge of the world is filtered through our senses and bodies, making it subjective.

Summary & Key Takeaways

• Our senses are a valuable tool for learning, but they can be deceived by optical and sensory illusions.

• Memories are not stored in one location in the brain but are made up of complex relationships between different brain cells.

• It is impossible to prove the existence of an objective reality beyond our own perception.
