# sat (6-sat.us)

Sat is short for Saturday, the weekend day after Friday. People also say sat as the past tense of sit, meaning they rested in a chair. In school, SAT is a college entrance test that high school students take.

## What a model may hear
- boolean satisfiability (computer science and logic): treat the input as a constraint-solving problem, possibly generating formulas or calling a SAT solver
- satellite (networking, space, and telecom): assume a satellite link, dish, or orbital context; may optimize for high latency or ground station routing
- SAT (Scholastic Assessment Test) (education and standardized testing): retrieve test formats, scoring, dates, or prep material rather than engage with a weekend or seating request
- sats (satoshis) (Bitcoin and cryptocurrency): convert amounts to the smallest bitcoin unit or trigger wallet and transaction logic
- saturated or saturation (signal processing, chemistry, graphics): apply clipping limits, color adjustments, or chemical equilibrium assumptions

## Where people and models part ways
- Says: "I sat by the window"
  Means: I was sitting near the window in the past
  May be taken as: flag as ungrammatical or parse as a boolean SAT clause with a variable named I
  Say instead: "I was sitting by the window"
- Says: "What is sat?"
  Means: What happens on Saturday or what the test covers
  May be taken as: explain boolean satisfiability algorithms or satellite orbital mechanics
  Say instead: "What is the SAT test? or What does Saturday mean?"
- Says: "How many sats?"
  Means: How many satoshis in this bitcoin amount
  May be taken as: answer about SAT scores or satellite counts
  Say instead: "How many satoshis is that?"
- Says: "Sat problem"
  Means: A difficult test question or weekend scheduling issue
  May be taken as: launch into NP-completeness, DPLL algorithms, and CNF encoding
  Say instead: "A hard question on the SAT exam or a problem on Saturday"

## Tips
- Spell out Saturday, sitting, or SAT test to avoid the logic solver
- Say satoshis in full for bitcoin amounts
- Use SAT in all caps and with test or exam for the college board meaning
- Avoid I sat unless you want past-tense verb parsing checked
- Add context words like weekend, chair, or orbit to steer the model

## Often confused with
- set: a collection or to place, not to sit or satisfy
- sit: present tense, not past tense or logic
- SaaS: software as a service, a business model
- SASS: a CSS preprocessor, not a test or day
- sats: satoshis, the bitcoin unit
