Resistor
Req = Equivalent Resistance
In Series
Req = R1 + R2 + R3 + ...
In Parallel
1/Req = 1/R1 + 1/R2 + 1/R3 + ...
| Black | Brown | Red | Orange | Yellow | Green | Blue | Violet | Grey | White |
| 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 |
(ex. Brown Black Red = 1000 = 1KΩ)
Atomic Number
Symbol is Z.
Equals the number of protons in a given atom.
Each unique atomic number corresponds with an element on the periodic table.

Proton
Subatomic particle with electric charge of +1e.
Mass is 1.672621637(83) * 10-27kg.
Exists as a nucleon in all atoms.
Exists independently as the hydrogen atom, H+.
Number in each atom (atomic number, Z) determines its element.
Composed of two up quarks and one down quark.
Quarks
From James Joyce, Finnegans Wake
“Three quarks for Muster Mark!”
Three being a natural organizational number for quarks,
color is also employed as a metaphor.

Elementary particle.
Never exist independently.
Up Quark
Symbol is u.
Elementary particle with electric charge of +2⁄3e.
Have gravitational, electromagnetic, weak, and strong interactions.
Stable quarks.
Down Quark
Symbol is d.
Elementary particle with electric charge of -1⁄3e.
Have gravitational, electromagnetic, weak, and strong interactions.
Stable quarks.
MCMC (Markov Chain Monte Carlo)
A class of algorithms used to find the probability distribution of an event given the probabilities of causally linked events.
Random walks are taken through the causal chain,
Random walks are taken through the causal chain,
the results of these walks eventually converging on a stationary distribution within an acceptable margin of error.
Cloud Etymology
Cloud
From Old English clud, “mass of rock”
a 13c. metaphoric extension of cumulus clouds to rock masses.
Old English word for “cloud” was weolcan,
but “cloud” has iconicity.

Alto
From Latin altus, “high”.
Cirrus
From Latin cirrus, “a lock of hair, tendril, curl, ringlet of hair; the fringe of a garment”
to the clouds in 1803.
Cumulus
From Latin cumulus, “a heap, pile, mass, surplus”
from PIE *ku-m-olo-,
suffixed shortened form of base *keue-, “to swell”.
Nimbus
To English in 1610s, “bright cloud surrounding a god”
from Latin nimbus, “cloud”
perhaps related to nebula, “cloud, mist”.
Stratus
From Latin stratus, “a spreading”.
