We can never fully grasp, define, or understand a system we are part of.
“Distance provides perspective” and wisdom in life is often about perspective.
The study of the large-scale behavior of systems exchanging work and heat with connected systems or their environment.
- The Transitive Law
- The Law of Conservation
- The “Contrast Advantage” Law
- The “Absolute Zero” Law
Describe how objects in the world move and react to forces.
- The Inertia Law: An object at rest, stays at rest
- Force = Mass * Acceleration (F = ma)
- The Law of Reciprocity: For every action there is an equal and opposite reaction
A complex system exhibits emergent behavior due to the collective interaction of many individual agents according to simple rules.
Complex systems are sensitive to original conditions, influenced by feedback loops, and buffeted by random outside variables.
Chaos leads to complicated, non-periodic behavior from iteration of a simple rule(s), whereas complexity leads to rich, collective behavior from simple interactions between large numbers of subunits.
Complexity lies in between order and chaos.
A process where higher-order behavior emerges from the interaction of lower-order components.
These smaller or simpler entities do not exhibit the properties that the higher-order entity ends up exhibiting.
The whole is greater than the sum of its parts.
The quantity of motion of a moving body, measured as a product of its mass and velocity: Momentum = Mass * Velocity
Momentum is broadly applicable outside of physics as it can help you understand how things change and how difficult or easy it is to change them.
Velocity has magnitude and direction whereas speed does not.
While nobody knows why nature favors velocity over mass, she does, and we should harness it.
There's a stark difference between potential energy and kinetic energy.
Friction is the force that causes the resistance felt when two objects are moving against one another.
Inertia is a prime example of friction.

I want to share my thoughts, as someone who has been so alarmed by the so-called "dissident" scientists like Gupta, Heneghan, Kuldorff, Bhattacharya, & Ioannidis who consider themselves brave Galileos unfairly treated by "establishment scientists." I will try not to swear. 1/n
I want to talk about 3 things:
‼️Their fringe views are inhumane, unethical junk science that promotes harm
‼️They complain that they've been marginalized but this is simply untrue
‼️I am sick of people telling me we have to "listen to both sides." There aren't 2 sides here 2/n
These 'dissident' scientists have consistently downplayed COVID-19, urging policymakers not to take aggressive control measures. They claim it is not a serious threat. Gupta even went on TV saying people under 65 shouldn't worry about it!
RECEIPTS
They have consistently argued that policymakers should just let the virus rip, in an attempt to reach herd immunity by natural infection. Kuldorff *continues* to argue for this even now that we have many highly effective, safe vaccines.
We've never controlled a deadly, contagious pandemic before by just letting the virus spread, as this approach kills & disables too many people. In Manaus, Brazil, 66% of the city was infected & an astonishing *1 in 500* people died of COVID-19
If this is true raises the question of why certain (fringe & unethical) views got access to No.10 while others were ignored... https://t.co/A75HrSEqo4

So it turns out that an organization I thought was doing good work, the False Memory Syndrome Foundation (associated with Center for Inquiry, James Randi, and Martin Gardner) was actually caping for pedophiles. Uhhhh oops?
Since this, bizarrely, turned out to be one of my longest videos ever (??) here's a quick thread to sum it up for those of you like myself with short attention spans. 1/10
In the '90s the False Memory Syndrome Foundation was founded to call attention to the problem of adults suddenly "remembering" child abuse that never actually happened, often under hypnosis. Skeptics like James Randi & Martin Gardner joined their board. 2/10
A new article reveals that the FMSF was founded by parents who had been credibly and PRIVATELY accused of molestation by their now-adult daughter. They publicized the accusation, destroyed the daughter's reputation, and started the foundation. 3/10
The FMSF assumed any accused pedo who joined was innocent, saying "We are a good-looking bunch of people, graying hair, well dressed, healthy, smiling; just about every person who has attended is someone you would surely find interesting and want to count as a friend" 😬 4/10

I’m torn on how to approach the idea of luck. I’m the first to admit that I am one of the luckiest people on the planet. To be born into a prosperous American family in 1960 with smart parents is to start life on third base. The odds against my very existence are astronomical.
I’ve always felt that the luckiest people I know had a talent for recognizing circumstances, not of their own making, that were conducive to a favorable outcome and their ability to quickly take advantage of them.
In other words, dumb luck was just that, it required no awareness on the person’s part, whereas “smart” luck involved awareness followed by action before the circumstances changed.
So, was I “lucky” to be born when I was—nothing I had any control over—and that I came of age just as huge databases and computers were advancing to the point where I could use those tools to write “What Works on Wall Street?” Absolutely.
Was I lucky to start my stock market investments near the peak of interest rates which allowed me to spend the majority of my adult life in a falling rate environment? Yup.

"Luck is the flip side of risk. They are mirrored cousins, driven by the same thing: You are one person in a 7 billion player game, and the accidental impact of other people\u2019s actions can be more consequential than your own."
