BIO DIVERSITY Variation = differences btwn organisms; physical (size, colour, shape) or behavioural.~Interspecific = btwn species. Intraspecific = within same species.~Species = organisms that can interbreed + produce fertile offspring.~Biodiversity = variety of life; ↑ variation = ↑ biodiversity.~Adaptation = variation that improves survival/reproduction.• Structural = physical trait• Behavioural = action/behaviour~Natural Selection: helpful variation → survive/reproduce → trait passed

T1 — Noiseless Digital Communication
Analog signal: Continuous value, varies continuously in time.
Digital signal: Discrete values only (e.g., 0/1).
ADC (Analog-to-Digital Converter): Sampling, then Quantization, then Encoding.
Sampling and Quantization
- Sampling: Periodic snapshots of the analog signal.
- Nyquist rate: Sample at least 2x the max frequency to reconstruct without loss.
- Quantization: Rounding each sample to the nearest discrete level.
- Quantization error/noise: Real value vs. assigned level;

Patriot Missile Failure: The Cost of Numerical Errors
The Patriot Missile Failure: A Numerical Disaster
The incident. On February 25, 1991, during the Gulf War, a U.S. Patriot missile battery at Dhahran, Saudi Arabia, failed to track and intercept an incoming Iraqi Scud missile. The Scud struck the barracks directly, killing 28 American soldiers and injuring around 100 others. The system had successfully intercepted Scuds before; the failure was not a hardware fault or enemy countermeasure, but a numerical software defect. This was documented in the
