These skills are quietly disappearing, one day you’ll need one, and nobody will know what to do. read: 1. Writing in Cursive

Over 20 U.S. states no longer require cursive in schools. Most Gen Z students can barely read cursive, let alone write it. The art of elegant handwriting is fading into history.

2. Reading an Analogue Clock

Many classrooms have replaced wall clocks with digital ones. In surveys, teachers report that 1 in 3 students can't read time on an analogue clock in the US.

Before we start this Zero-Base Physics Challenge, you need one core concept:

Physics isn’t hard. It’s stacked.
Miss the lower layers → the upper layers feel impossible.

So this is not a “24-week deadline course.”
This is 24 layers (an academic roadmap).
Learn in the right order.
Move at your own speed.

Here’s the roadmap + learning outcomes: Phase 1 — Mechanics Foundations (Layers 1–8) (the backbone)

Topics: Inertia → Forces/FBD → Newton → Friction/constraints → Work/Energy → Conservation → Momentum/Impulse → SHM

I’m 54, a physicist, have spent decades using mathematics to study the universe, solve problems, and build things.

If your work touches numbers, now or in the future, and you want to learn math properly, this thread shows a from-the-ground-up math you’ll actually need: The roadmap has two parts.

The first 25 threads follow this diagram:

Algebra → Geometry → Trigonometry → Precalculus → Calculus → Linear Algebra & Multivariable Calculus

After that, we map this math to real careers. Make sure to bookmark, you’ll need it later.

I’m Kekius Maximus, CEO of several companies.

I’m going to share a few everyday physics facts that will change how you see the world forever, so if you’re curious, read this: 1) You don’t actually “touch” anything.
→ What you feel as touch is electromagnetic repulsion between electrons, plus the Pauli exclusion principle preventing them from overlapping. It’s pushback, not atoms pressing together.

2) Solid objects are mostly empty space.
→ Atoms are like tiny solar systems: a minuscule nucleus with electrons around it. “Hardness” comes from forces and structure, not from being packed solid.

I’m a 54-year-old low-tech dinosaur. I can barely find the settings menu.
Still made $3,000 on X last month by posting about physics, cosmos stuff.

If you’re still young and want to build a side hustle on X, read this: 1. Start with the basics (eligibility) for at least 6 months.
2. Pick one lane first for at least 6 months. Ads rev share, subs, affiliates, sponsors. Choose one to learn before stacking the rest.

I’m 54, a physicist who’s spent decades unraveling the universe’s secrets—from quantum quirks to cosmic scales.

If you’re in your 20s and passionate about physics or science, please read this: 1. Build your mathematical foundation early. Calculus, linear algebra, and differential equations are your tools—master them like a craftsman.
2. Experiment relentlessly. Theory is great, but hands-on labs teach you the chaos of real data. Start with simple setups at home.
