CUDA and GPU Architecture
- Core Intuition: Data parallelism (same operations on many independent data points).
- GPU vs. CPU Cores: GPU cores are weaker individually but significantly more numerous (10,000+ in modern data centers).
- CPU Strengths: Sequential, branchy, and latency-bound workloads.
- CPU Silicon Investment: Branch predictors, caches, and deep pipelines.
- Latency Hiding: GPUs use thread oversubscription (warp switching).
- SIMT (Single Instruction, Multiple Threads): Allows per-thread program counters.

Diffusion and Osmosis: Principles of Passive Transport
Understanding Diffusion
Diffusion is the net movement of particles from an area of high concentration to an area of low concentration.
Key Characteristics of Diffusion
- It happens in liquids and gases.
- Particles move randomly all the time.
- It is a passive process.
- It does not need energy from the cell.
Diffusion in Biological Cells
Cell membranes are partially permeable. This means:
- Small molecules can pass.
- Large molecules cannot pass easily.
Diffusion happens across the membrane when there is a concentration
