The force that drops an apple also holds the Moon. F = G m₁m₂ / r² At Earth's surface g ≈ 9.8 m/s². The Moon is about 60 Earth radii away, so gravity there is 60² = 3600 times weaker: about 2.7 mm/s², the acceleration that keeps it in orbit. Throw a cannonball at about 7.9 km/s and it falls around the Earth instead of into it. An orbit is a fall that never lands.

Three equations. Infinite complexity. The system is dx/dt = σ(y − x), dy/dt = x(ρ − z) − y, dz/dt = xy − βz. With σ = 10, ρ = 28, β = 8/3 the flow settles onto a strange attractor whose dimension is non-integer. Nearby points separate at an exponential rate yet never leave the bounded region. The time-colored trajectory and its plane projections expose the stretching and folding that sustain chaos. Deterministic rules can refuse to repeat.

A single number is already a tensor. Add one index and it becomes a vector. Add a second and you have a matrix. Add a third and the array becomes a cube of numbers. Each step simply increases the number of indices needed to pick out one entry. Rank is that count: 0 for a scalar, 1 for a vector, 2 for a matrix, 3 or more for a full tensor. The same rules of addition and multiplication apply at every level. Tensors are not a new kind of object. They are the general case that includes everything else.

🚨 JUST NOW: President Trump says it PERFECTLY "Sadly, if you import people from Third World Countries, you quickly become a Third World Country — And there’s not a thing you can do about it. MAKE AMERICA GREAT AGAIN!" Import the 3rd world, become the 3rd world.

🚨 BREAKING: President Trump says NO MORE SOMALIANS in the USA. He's DONE. "Their country STINKS! They contribute NOTHING." 💯 "I don't want 'em, to be honest. OK? Some say, that's not politically correct. I DON'T CARE. I don't want them in our country. Their country's no good for a reason!" "I'm understanding Somalians ripped Minnesota that place for BILLIONS of dollars! And they contribute NOTHING. The welfare's like 88%!" "I always watch [Ilhan Omar] complain about our Constitution, how she's treated 'badly,' or it's a bad place, hates Jewish people, hate's everybody. She's a TERRIBLE person." "I watch what's happening in Minnesota, the land of a thousand lakes? This beautiful place, I see these people RIPPING it off."

Hungarian Healthcare is a total garbage and with the new government they will land on the bottom of the list. This is the best example how you kill slowly a nation. worldpopulationreview.com/co…
