Hi 👋, I'm [Paras Chopra](https://invertedpassion.com/) and **you're looking at my knowledge garden**, a place where I publish my raw notes and thoughts. Some of these notes graduate to become [self-contained essays](https://invertedpassion.com/essays/), while others remain seeded here, patiently waiting to be groomed someday. > ⚠️ **Writings here are raw and haven't been edited**, so expect grammatical and coherence issues at multiple places. ### Introduction - [[Foundational questions of reality]] ### Knowledge related - [[Defining reality]] - [[Philosophy of science]] - [[Why fundamental reality is describable using mathematics]] - [[Understanding as hierarchical model building]] - From my blog: - [How much can science tell us about reality?](https://invertedpassion.com/science-and-reality/) - [How we do science determines what we discover](https://invertedpassion.com/how-we-do-science-determines-what-we-discover/) - [Reality is an evolved illusion](https://invertedpassion.com/reality-is-an-evolved-illusion/) - [Life is fractal, but markets are square](https://invertedpassion.com/life-is-fractal-markets-are-square/) - [The meaning of life is unthinkable](https://invertedpassion.com/the-meaning-of-life-is-unthinkable/) - [Philosophy is politics](https://invertedpassion.com/philosophy-is-politics/) - [The Outer Limits of Reason: A Summary](https://invertedpassion.com/the-outer-limits-of-reason-a-summary/) ### Universe related #### Demystifying fundamental theories - [[Demystifying quantum theory]] - [[Demystifying special relativity]] - [[Demystifying general relativity]] - [[Demystifying the arrow of time]] - [[Demystifying mass and energy]] - [[Demystifying the first three minutes of the universe]] - [[Mysteries of the Big Bang and Cosmic Inflation]] - [[Demystifying entropy]] - [[Demystifying gauge theories and standard model]] #### Hints towards reality - [[Quantum entanglement between two distant particles]] - [[On determinism vs indeterminism of reality]] ### Consciousness related - [[What is consciousness?]] - [[What is a Self?]] - [[Causal mechanisms for consciousness and suffering]] - [[Evolution of brains, consciousness and suffering]] - [[What non-living things are conscious]] - [[If panpsychism is true, what systems are capable of suffering]] - [[Constraints physical laws put on consciousness]] - [[Why we dont have a science of consciousness yet]] - [[Towards building a theory of consciousness]] - From my blog - [Notes from the book: “The Spike”](https://invertedpassion.com/notes-from-the-book-the-spike/) - [Notes from the book “The Mind is Flat”](https://invertedpassion.com/notes-from-the-book-the-mind-is-flat/) #### Artificial consciousness - [[Foundational work on artificial consciousness]] #### Consciousness-related medical opportunities - [[Tinittus]] #### Neurotechnology - [[Overview of brain input-output techniques]] - [[Medical uses of BCI]] - Prosthetics / Bionic limbs - [[User challenges and benefits of bionic prosthetic arms]] - [[Types of bionic limbs with brain-interface]] - Implantable electrodes - [[Neuralink impalntable device]] - [[Polymer based neural implants]] - [[Surgery for neural implants]] - [[Commercial neurotechnology available for research]] - [[Fast optical signal for non-invasive neural spike detection]] - [[Why brain-machine interfaces progress so slowly]] ### Goodness related - [[Choosing projects that reduce suffering]] - What is [[Suffering focused ethics]]?
