taxicab number, characteristic (details), background story.
1729, the smallest number that is the sum of two cubes in two different ways (1^3+12^3 and 9^3+10^3), mentioned by Srinivasa Ramanujan to GH Hardy when commenting about a number on a London cab.
formula for the derivative of a polynomial
where f(x) = ax^n + b
f(x)’ = nax^(n-1) + 0
quadratic formula
x = (-b +/- √[b^2 - 4ac])/2a
Define RNN + LLM
Recurrent Reural Network (RNN) plus Large Language Model (LLM) equals receptance weighted key value (RWKV)
drug that reduces glucose levels, effects similar to insulin (full name)
GLP-1 RA (glucagon-like peptide-1 receptor agonist)
Trig derivatives
sin’(x) = cos(x)
cos’(x) = -sin(x)
tan’(x) = sec^2(x)
Product Rule
(uv)’ = u’v + v’*u
Quotient Rule 
(u/v)’ = (u’v - v’u)/v^2
Chain Rule
{g[f(x)]}’ = g’[f(x)] * [f(x)]’
failed anti-inflammatory that shows promise as a snakebite antivenom
Varespladib
3 common oaks of California, in order of increasing size (Linnean name)
scrub oak (Quercus berberidifolia)
live oak (Quercus agrifolia)
valley oak (Quercus lobata)
CRISPR-Cas9 full name; function
clustered regularly interspaced short palindromic repeats + CRISPR-associated protein 9 ;
gene-editing chemical derived from bacteria that use it to disable bacteriophages
common SoCal hillside plant, not the poisonous variety (scientific name)
laurel sumac (Malosma laurina)
Kuiper Belt object visited by New Horizons spacecraft 2019 Jan 01 (early informal name)
Arrokoth (Ultima Thule)
unable to think past a single idea
Einstellung effect
Planck constant, use, formula
h = 6.62607015×10^−34 J⋅sec
for calculating the energy of a photon, as:
E = hF ,
where
E = energy of photon
h = Planck constant
F = frequency (cycles per second)
reduced Planck constant symbol, derivation, value
ħ (pronounced h-bar) = h/2π = 1.054571817×10^−34Js
Mohs scale list, mnemonic
1 talc
2 gypsum
3 calcite
4 fluorite
5 apetite
6 orthoclase
7 quartz
8 topaz
9 corundum
10 diamond
Terrible Giants Can Find Alligators
Or Quaint Trolls Conveniently Digestible
5 skin layers from deep to superficial
stratum basale
stratum spinosum
stratum granulosum
stratum lucidum
stratum corneum
density formula, pronunciation
ρ = m/V = kg/m^3
“rho equals mass divided by Volume”
(NOTE: “ρ” is italicized)
force formula, force unit
F = ma
newton = 1kgm/s^2
work equation (SI unit)
J = f x d (joule)
w = (ma) x d
work = force x distance
J = N x m
J = 1kg x 1m/s^2 = 1kgm^2/s^2
AI HHH principle
helpful, honest, harmless
skills and abilities that are hard to teach (as opposed to formal info like math or history)
tacit knowledge
