  • “The Dorito Effect” by Mark Schatzker

    • Heinz bought Weight Watchers
    • Obesity is the second most common cause of death
    • Type 2 Diabetes used to be called “Adult onset diabetes” but was renamed because so many kids have it
    • Flavor is the original craving
    • Flavor detection is the largest chapter of our genome
    • Chickens needs more than corn to live
    • Vitamins were discovered, revolutionized plant and animal growth
    • Young animals lack the flavor of adults
    • Fried chicken used to only need salt and pepper, now it needs all sorts of spices to flavor it up
    • “Further processing” is when we add flavor back into things
    • Chicken strips are in their way out because chicken nugget eaters are getting older and think strips are too tough
    • Carbs and water are replacing flavor while letting things grow faster
    • The importance of vine ripening is the energy to make sugars
    • Imitation vanilla started with pine cones
    • “Need states” track what people are looking for across demographics
    • Restaurant kitchens are more like prep areas
    • Raw meat and almost everything else has some flavoring
    • Natural vs artificial flavoring is about the extraction method, not the chemicals themselves
    • A hundred years ago, we used 0.5 pounds of spices per person per year, now it is close to 3.5 pounds
    • Flavor dilution is affecting almost everything
    • Food addicts crave food more and are satisfied lees
    • Substance abuse is a continuum
    • Making a narcotic more available increases addiction
    • The human nose was not meant to sniff but to taste food
    • Plants send caterpillar specific chemicals as they are being eaten
    • Flavor cravings are learned and can be connected with nutrients
    • “A little bit of something bad could be good”
    • Anti-oxidant pills do not do much
    • Flavors drive feels
    • Left with natural food, children naturally balance their diets on their own
    • “Throat burn” is a sign of good olive oil
    • Artificial sweeteners are not reducing calorie consumptions
    • Adding micronutrients confuses the body because we can no longer associate nutrients with food
    • Glutathione makes things taste better but only if paired with other things
    • The gut has taste sensors too
    • Most animals stop eating to avoid an overdose, not because they are full
    • Adding a fruity aroma to water makes it taste sweeter
    • Appendix
      • Where did the flavor come from?
      • Try different foods
      • Eat foods that you find satisfying
  • “Shifting the Monkey” by Todd Whitaker

    • “Monkeys have shifted to the wrong peoples’ backs”
    • Don’t let monkeys move
    • Ask
      • Where is the monkey
      • Where should the monkey be
      • How do I shift it to where it belongs
    • Treat everyone well
    • Protect your best people first
    • Assume good intentions
    • Ignore excuses
    • Try to not have barriers between you and someone else
    • Give targeted feedback for underachievers
      • (This is to prevent them from spiring under your feedback)
    • Try to not threaten
      • Only threaten when you mean it and can act on it
    • Let them know how peers are responding
      • (A little bit of peer pressure is nice 😁)
    • Ask if everything is all right before jumping into questions
    • “Give anonymous public praise”
      • So people acting good get praise and people acting poorly become generally jealous
    • Focus on correcting behavior, not changing minds
    • Efforts matter more than results
    • Offer to talk outside of working hours to filter “nonsense” requests
    • Give permission to not volunteer (especially to high achievers)
    • “Discover” errors together with good employees
    • “Treat everyone well but not equally”
    • Let people resent you but not your best people
  • “Seeing With Fresh Eyes” by Edward Tufte

    • Autocorrelation, serial correlation, bang-bang duplicate,  or pseudo-replications are when a piece of data follows another without new measures
    • There is a difference between having questions to be solved by a database and poking around a database looking for interesting answers to question
    • Early screening boosts “survival time” in useless ways
    • Adjust measures to avoid errors rather than modeling them away
    • “Guide to Bad Data” by Chris Groskopf
      • Values missing
      • Zeros replace missing values
      • Data missing that you know should be there
      • Rows or values duplicated
      • Total differ from aggregates
      • Suspicious values present
      • Spreadsheet have 65536 rows or 255 columns
      • Margin-of-error to large or unknown
      • Benford’s Law fails
      • Too good to be true
    • Fix bad names immediately
    • Survivor bias: “Most medieval castles were made of wood”
  • “Time Travel” by James Gleick

    • Concepts of time travel started in 1914
    • 1876 was the first record of a centennial celebration
    • No one pondered the future or the past until the 20th century
    • New (remote) lands filled the roles of time travel in fiction
    • We should not think about time as the same as space
      • We cannot freely move through time like we can through space
    • “What the balloon does for space, the time machine does for time”
    • Prior to clocks, time was relative based on the setting
    • Newton has to define time so acceleration could happen
    • “If the speed of light is fixed then time cannot be.”
    • The Olympics replace starting pistols with speakers to ensure everyone can hear the signal at the same time
    • “Souls cannot move that fast so one needs to wait”
    • We are always looking into the past
    • All time was local until the train
    • Is the arrow of time because of entropy?
    • “You cannot stir things apart”
    • In many Latinx cultures, you look forward to the past and back for the future
      • (This makes a lot of sense because you observe the past, in front of you, and cannot see the future coming behind you)
    • Eternity is “outside of time”
    • Nostalgia originally meant “homesick”, not wanting a different time
    • In 1955, we redefined “a second” from a fraction of a day to an independent time frame
    • A nano second is about the length light travels a foot
    • Mental Time Travel let’s us project forward and back over time
    • “Now” is generally 2-3 seconds lumped together by the brain
    • We need at least 1/10th a second to accurately differentiate the order of two events
  • “Chaos: Making a new science” by James Gleick

    • Science became really interesting when looking at weather
    • Warm coffee just cools; Hot coffee has convection
    • Modern scientist have iterated on the past but that assumes everything that came before was true
    • “Sensitive dependance on initial conditions”
    • Physics and maths divorced in the 30’s but started getting back together in the 60’s
    • When studying systems, scientists tended to assume oscillation was around a steady state
    •  Measuring non-standard shapes requires an infinitely small measuring tool
    • Fractals allow for infinite length in a finite space
    • “Dimensions” are the number of identifiers needed to identify a single point
      • At a distance, a ball of string is a point and so one-dimensional; up close it is a one-dimensional object arranged to occupy three dimensions
    • All physical touching is described by fractals
    • Turbulence is very poorly understood and may be unknowable
    • The Manhattan project was really about turbulence
    • Attractors bring stability, even if not predictability
    • Poincare return map
      • Cross sections of the transit to track movement over time
    • In order to be universal, it has to have scale
    • Universality was originally rejected from publication
    • Flow = shape +  change or motion + form
    • Control the space so you can manipulate time
    • https://en.wikipedia.org/wiki/Mandelbrot_set
    • “In biology, randomness is death”
    • https://en.wikipedia.org/wiki/Barnsley_fern
    • Computer experimentation really let fractals take off
    • https://en.m.wikipedia.org/wiki/Lorenz_system
    • Random (spread out and undefined) vs chaos (deterministic and patterned)
    • Chaos brings a wealth of information (because steady states can have their information compressed)
    • A map needs to simplify the things it maps
    • Giving mosquitos a photo burst at midnight will destroy their circadian signals
    • Mode locking is when things lock into frequencies
    • “Is it possible that mathematical pathology, i.e. chaos, is health and that mathematical health, which is the predictability and differentiability of this kind of structure is disease?”
    • Snowflake’s non-equilibrium phenomenon
      • They have 6 sides based on the stress of surface tension
