La palabra Ingeniería, proviene del latín, inteligencia, genialidad o talento para inventar cosas. Se asoció a la matemática y producen genialidades como esta.

Richard Feynman said light crosses an atomic nucleus in 10⁻²³ seconds and nobody will ever see it happen.

He built the case by hanging a bowling ball from a 25-foot ceiling and timing its swing with his own pulse. Galileo did the same thing in a church, centuries earlier.

Human eyes can't separate anything under 0.01 seconds. Slow a film to 6 frames a second and motion turns choppy. Below that threshold, everything blurs into one smooth lie.

So Feynman went smaller.

2 cesium clocks ran side by side for 3 days. They drifted by only a few parts in 10¹¹.

That's 1 second of error every 3,000 years.

Then smaller again. A flash bulb burns for 0.1 seconds on an oscilloscope. A bullet gets photographed twice, 100 microseconds apart. A particle leaves a 3×10⁻⁵-centimeter track, crossed in about 10⁻¹⁵ seconds.

Then the floor gave out.

Light crosses an atom in 10⁻¹⁸ seconds.

Light crosses a nucleus in 10⁻²³ seconds.

Nobody has recorded that number happening. Nobody ever will.

"You can't observe those times - you can only imagine them."

In Boolean algebra, De Morgan’s Laws help simplify logic circuits:

1. NOT (A · B) = A̅ + B̅
AND → OR, and invert each input.

2. NOT (A + B) = A̅ · B̅
OR → AND, and invert each input.

Simple rule:
Break the bar → change AND ↔ OR.

Escape velocity is the speed needed to leave a planet’s gravity without any further push. It depends only on the body’s mass and radius:

vₑ = √(2GM/r)

For Earth, that is about 11.2 km/s. The interesting part is that the escaping object’s own mass cancels out, so a tiny probe and a massive spacecraft need the same escape velocity from the same starting point.

PID Control: The Hidden Algorithm Behind Robotics. 🤖⚙️

You may not see it, but PID control is everywhere in robotics.

From robot arms and mobile robots to motors and industrial automation, PID helps machines maintain precise motion, speed and position.

P — reacts to the current error
I — corrects accumulated error
D — responds to the rate of change

No AI. No machine learning.

Just control theory working behind the scenes to make robots move accurately and consistently.

If you could master ONE control algorithm in robotics, would you choose PID? 👇

Gravity is not a force. It is spacetime itself curving around mass.

For any spherical mass M, Einstein’s vacuum equations have an exact solution: the Schwarzschild metric.

ds² = −(1 − 2GM/c²r) c² dt² + (1 − 2GM/c²r)⁻¹ dr² + r² (dθ² + sin²θ dφ²)

When r = 2GM/c² the time term vanishes and the radial term diverges. That surface is the event horizon.

GPS satellites, gravitational redshift, and the first black-hole images all live inside this geometry.

The simplest exact solution of Einstein’s equations still governs the darkest objects in the universe.

Transparent weather strip keeps the fix subtle around glass while still adding a flexible barrier along the open edge.
Use it where you want the gap covered without making the repair the first thing people notice.

A CHILD-SIZED ROBOT IS WALKING THROUGH AN EXPO HOLDING A MAN'S HAND AND LOOKING UP AT HIM LIKE IT NEEDS PERMISSION TO CROSS THE STREET.

PrimeBOT. a small grey humanoid the size of a 4-year-old. glowing purple eyes. it reaches up and grabs a man's hand. walks next to him through a crowded expo floor. looks up at his face. tilts its head. moves at his pace. stays close. like a kid at a mall who's scared of losing dad in the crowd.

the man holds its hand like it's NORMAL. doesn't laugh. doesn't pull away. just walks. and every person they pass stops and films.

the global birth rate is falling off a cliff. Japan's population dropped by 800,000 last year. South Korea's birth rate hit 0.72. the LOWEST in human history. 44% of young adults in the US say they don't plan to have children. EVER.

and somebody just built a robot that holds your hand. looks up at you. follows you around. and never grows up.

raising a child in the US costs $310,000 from birth to age 18. THREE HUNDRED AND TEN THOUSAND DOLLARS. diapers. school. clothes. food. healthcare. college is another $100,000-$300,000 on top.

this robot costs a fraction of that. doesn't need school. doesn't need diapers. doesn't scream at 3am. doesn't go through a phase where it hates you for two years. it just holds your hand and looks up at you forever.

the people filming think this is cute. the people who can't have children think this is a product. the people who chose not to have children think this is confirmation.

the companion market is racing to $15 BILLION by 2030. and NOBODY is talking about the part of that market that looks like a kid and fits in the space where a child used to be.

still think robot companions are just for lonely men?
this one holds your hand like a child. and never lets go.
