Useful Knots You Should Know

I'm thrilled to share this unique collaboration with Artemis Il astronaut @astro_reid.

Artemis II was a unique opportunity to get high-quality imagery of the moon, and Reid was gracious enough to capture some special image sets for me during the lunar flyby.

Old television, known as CRT (Cathode Ray Tube) TVs, were essentially big, vaccum-sealed glass bottles that used a beam of electricity to "paint" pictures on the screen.

🚨 BREAKING: We’re now filming fusion plasma at 100 million °C in real time.

This isn’t CGI.

This is inside the ST40 fusion reactor.
At temperatures hotter than the core of the Sun,
matter becomes plasma a state where atoms are ripped apart.
And for the first time…
We can actually see it evolve.
This is the same process that powers stars.

If we can control it:
Unlimited clean energy
No carbon emissions
Virtually endless fuel
The future of energy isn’t theoretical anymore.
It’s glowing… right in front of us.
What do you think
Will fusion solve energy in our lifetime?

Follow me I break down the physics behind the biggest breakthroughs.

This automation is great!
Sadly has taken away manufacturing jobs. Someone's great Grandpa used to wind those armature and stator windings by hand!

[Mathematica @mathemetica]

F = q(E + v × B)

Watching the Lorentz force go from a textbook abstraction to 30,000 RPM in real-time is pure dopamine for the brain. It’s all fun and games until the magnetic field flux becomes a physical blur.

Most people see a "spinning toy," but we see the cross product of velocity and magnetic field vectors working in perfect, violent harmony. The torque on that armature is proof that Maxwell’s equations aren't just ink on paper: they are the literal pulse of the universe.

This shows the foundational principle behind DC Electric Motors.

Every cut, angle, and surface here is the result of extreme precision controlled down to fractions of a millimeter.

CNC machining turns solid metal into complex, perfectly balanced components that move with almost no resistance.

Why do turboprop aircraft STILL exist in the jet age? ✈️⚙️
Because they’re crazy efficient where jets aren’t. 👇

🔹 Short runways? Turboprops dominate. They deliver more thrust at low speeds, making them perfect for remote, regional, and mountain airports.
🔹 Fuel efficiency: They burn way less fuel than turbojets on short flights—saving airlines millions.
🔹 Lower operating costs: Cheaper to maintain, cheaper to operate, and cheaper to fly.
🔹 Better climb at low speeds: Perfect for routes under 500 miles where jets waste energy.

Turbojets rule the skies at high altitude and long distances…
But turboprops?
They’re the undisputed kings of short-haul performance and efficiency.

That’s why they’re still here — and they’re not going anywhere. 🔥
