Doing is normally distributed; Learning is log-normal

CEO total compensation has outpaced US median annual income by 16,638%, on average.

US median annual income increased by just 4% on average ($2,108/year).

CEO total compensation had an average annual increase of 7% ($676,153/year

Since 1974, CEO compensation has grown 940% while the average worker’s compensation has risen just 12%. Meanwhile, the purchasing power of the dollar over that same period has decreased an average of 3% a year from inflation. As a result, the average worker can afford significantly less goods and services today than they could 50 years ago, including housing, clothes and food. The average worker is losing big time.

And for those who would argue the high cost of social welfare, corporate welfare will cost taxpayers almost $400 billion this year alone, which is 25,000% higher than the $1.6 billion that will be spent on social welfare.

It’s becoming clear that deterministic physics cannot easily answer all aspects of nature, at astronomical and biological level.
Is this a limitation in modern mathematics and/or tools. Or an actual barrier?

The 𝐓𝐡𝐫𝐞𝐞-𝐁𝐨𝐝𝐲 𝐏𝐫𝐨𝐛𝐥𝐞𝐦 is one of the most enduring challenges in celestial mechanics, addressing the complex motion of three celestial bodies interacting under gravity. Governed by Newton’s laws of motion and the law of universal gravitation, it seeks to predict the paths of the bodies based on their masses, positions, and velocities. While the Two-Body Problem has exact solutions described by Kepler’s laws, introducing a third body leads to a nonlinear system of equations with no general analytical solution. This complexity arises from the chaotic interactions between the bodies, where even minute changes in initial conditions can lead to vastly different trajectories—a key aspect of chaos theory.

Historically, the Three-Body Problem has fascinated some of the greatest scientific minds. Isaac Newton laid its foundation, but it was Joseph-Louis Lagrange and Leonhard Euler who discovered specific cases with periodic or predictable solutions. Lagrange identified the Lagrange points, stable positions where the gravitational forces and motion of the three bodies balance, while Euler found collinear solutions, where the bodies align on a single line periodically. These solutions, though special cases, have profound implications for space exploration, such as identifying stable regions for satellites orbits.

Despite the chaotic nature of the Three-Body Problem, researchers have discovered periodic solutions where the bodies follow repetitive paths, returning to their original positions after a fixed time. In the 1970s, Michel Hénon, Roger A. Broucke, and George Hadjidemetriou identified a fascinating family of such solutions, now known as the Broucke–Hénon–Hadjidemetriou family. These solutions often involve symmetric and elegant trajectories, such as the figure-eight orbit, where three equal-mass bodies chase each other along a shared path resembling the number eight.

Other periodic solutions include equilateral triangle configurations (where the bodies maintain a triangular shape while rotating or oscillating) and collinear periodic orbits (where the bodies periodically align and reverse directions). These solutions highlight the intricate balance between gravitational forces and motion, offering glimpses of stability within the chaos.

While the Three-Body Problem laid the groundwork for understanding gravitational interactions, the study of higher n-body problems reveals the rich and chaotic dynamics of larger systems, offering critical insights into both cosmic structures and practical applications like orbital dynamics.

The prevalence of myopia is increasing rapidly, with projections indicating that by 2050, around half of the global population could be affected. This surge is largely attributed to lifestyle changes, such as increased time spent indoors and on screens, and decreased outdoor activities, starting with the Covid lock down.

To combat this epidemic, researchers are advocating for more outdoor exposure for children, as natural light is beneficial in slowing the progression of myopia. They also emphasize the importance of regular eye check-ups and early interventions. Additionally, innovative treatments such as specially designed contact lenses and low-dose atropine eye drops are being explored to manage and reduce the progression of myopia.

Ever since the philosopher Nick Bostrom proposed in the Philosophical Quarterly that the universe and everything in it might be a simulation, there has been intense public speculation and debate about the nature of reality.

Yet there have been skeptics. Physicist Frank Wilczek has argued that there’s too much wasted complexity in our universe for it to be simulated. Building complexity requires energy and time.

To understand if we live in a simulation we need to start by looking at the fact that we already have computers running all kinds of simulations for lower level “intelligences” or algorithms.

All computing hardware leaves an artifact of its existence within the world of the simulation it is running. This artifact is the processor speed.
No matter how complete the simulation is, the processor speed would intervene in the operations of the simulation.

If we live in a simulation, then our universe should also have such an artifact. We can now begin to articulate some properties of this artifact that would help us in our search for such an artifact in our universe.
The artifact presents itself in the simulated world as an upper limit.

Now that we have some defining features of the artifact, of course it becomes clear what the artifact manifests itself as within our universe. The artifact is manifested as the speed of light.
This maximum speed is the speed of light. We don’t know what hardware is running the simulation of our universe or what properties it has, but one thing we can say now is that the memory container size for the variable space would be about 300,000 kilometers if the processor performed one operation per second.

We can see now that the speed of light meets all the criteria of a hardware artifact identified in our observation of our own computer builds. It remains the same irrespective of observer (simulated) speed, it is observed as a maximum limit, it is unexplainable by the physics of the universe, and it is absolute. The speed of light is a hardware artifact showing we live in a simulated universe.

Consciousness is an integrated (combining five senses) subjective interface between the self and the rest of the universe. The only reasonable explanation for its existence is that it is there to be an “experience”.

So here we are generating this product called consciousness that we apparently don’t have a use for, that is an experience and hence must serve as an experience. The only logical next step is to surmise that this product serves someone else.

1. Name the five wealthiest people in the world.
2. Name the last five Heisman trophy winners.
3. Name the last five winners of the Miss America pageant.
4.  Name ten people who have won the Nobel or Pulitzer Prize.
5. Name the last half dozen Academy Award winners for best actor and actress.
6. Name the last decade’s worth of World Series winners.

How did you do?
The point is, none of us remember the headliners of yesterday.
These are no second-rate achievers.

They are the best in their fields.
But the applause dies.
Awards tarnish …
Achievements are forgotten.
Accolades and certificates are buried with their owners.

Here’s another quiz. See how you do on this one:

1. List a few teachers who aided your journey through school.
2. Name three friends who have helped you through a difficult time.
3. Name five people who have taught you something worthwhile.
4. Think of a few people who have made you feel appreciated and special.
5. Think of five people you enjoy spending time with.
