• chemical equations (varied!)
• power
• percent
• range: pH 1-2 , heart rate 60-80
• number (notation #2 for "number 2")
• pH (power-of-hydrogen,acidity,basicity)
• concentration - [H^+]
• note double-positive ions - Fe^{++} and Fe^{⊕⊕} see https://en.wikipedia.org/wiki/Ion

### Biology concepts:

• codon - example CAG, CGA, UUG
• dna-sequence - example CAGTATACG
• :amino-acid - notation leu, arg, his (leucine, arginine, histidine)
• auxotrophic/not-auxotrophic - notation leu^{-} arg^{+}
• dna-strand - example `5'-CTTA` but also `AATTC-3'` - dash is silent, prime is spoken.
• blood-pressure - 120/80 spoken "120 over 80"
• genotype - I^A - spoken concatenated "cap I cap A"
• embellished name - X^cY - for "color-blind son", but likely spoken "cap X c cap Y" or such?
