5 TAKEAWAYS AND 1 TASK ABOUT SCIENTIFIC MODELS:

WHAT ARE THEY AND WHAT DO THEY DO?

TASK; NAME 3 OF YOUR FAVORITES MODELS

1. MODELS REPRESENT WAYS OF THINKING.

NICOLA TESLA 1885 INVENTED THE PHYSICAL 3-PHASE

GENERATOR OF ELECTROMAGNETIC WORK,

KARL FRISTON IN 2014 DESCRIBED THE MENTAL

NEUROSCIENTIFIC WORK OF BELIEF.

WE WILL SHOW SOME HISTORICAL DETAILS OF EACH, BUT FOCUS ON THE

WHOLISTIC MEANING OF THESE MODERN MODELS OF UNDERSTANDING.

WHAT IS A GOOD SCIENTIFIC MODEL?

2010 “REALITY IS MODEL DEPENTENT”

WHAT IS A GOOD SCIENTIFIC MODEL?

1. ELEGANT (equation, drawing, recipe, demonstration).

2. CONTAINS…FEW ARBITRARY ELEMENTS.

3. EXPLAINS… ALL OBSERVATIONS.

4. PREDICTS… DISPROVABLE FEATURES.

PROPERSCIENTIFIC METHOD

1. RANDOMIZED CONTROLED SELECTION,

AND2. PEER REVIEW

Nikola Tesla 10 July 1856 – 7 January 1943)

Serbian-American[4][5][6] inventor, electrical engineer,

mechanical engineer, and futurist known for the

design of the modern Alternating Current (AC)

Electricity supply system. 1893.[7]

Karl Friston 12 July 1959 –60 y.o.

British psychiatrist and neuroscientist known for the

Design of the modern Free Energy Principle, and a

(Reality-Belief supply system 2014.

QUESTION: HOW DO I KEEP THE GOLF BALL IN THE FAIRWAY (MIDDLE)?

2. HIT OFF THE TEE 9 TIMES.

5. CORRECT SLICE FIRST

4. CHOOSE AGENERATIVEMODEL

3. 5 IN FAIRWAY BUT NOT VERY FAR,3 SLICE RIGHT,1 HOOKS LEFT,

6. SWING MOREINSIDE OUT.

RIGHTHANDED SWING: OUTSIDE IN-SLICERIGHTHANDED SWING INSIDE OUT –HOOK

MENTAL HEALTH:SENSORY ANALYSISWHAT IS REAL?

QUESTION AFTER 10 YEARS WITH AN OLLI GROUP OF GOLFERS, WHAT HAVEI LEARNED TO CORRECT, DECREASE UNCERTAINTY AND INCREASE FREE ENERGY?

5. WITH MOREFREE ENERGY,

I CAN BETTERENJOY MY FRIENDSAND NATURE

4. MODELING ANGLES OFF CENTER PROVIDESMORE USEFUL DATA THAN

MODELING DISTANCE MEASUREMENTS.

3. THE HARDER I SWING, THE WORST IT GETS.BUT,BALACING RIGHT AND LEFT ARMS WORKS.

6. INCREASED ENJOYMENTHAS LITTLE TO DO WITH SCORE…WHICHHASN’T CHANGED MUCH.
