Plate tectonics is a scientific theory that describes the large-scale motions of Earth’s lithosphere. The model builds on the concepts of continental drift, developed during the first decades of the 20th century. It was accepted by the geoscientific community after the concepts of seafloor spreading were developed in the late 1950s and early 1960s.
“Imagine” is a song written and performed by the English musician John Lennon. The best-selling single of his solo career, its lyrics encourage the listener to imagine a world at peace, without the divisiveness and barriers of borders, religions and nationalities, and to consider the possibility that the focus of humanity should be living a life unattached to material possessions.
The Fermi paradox is the apparent contradiction between high estimates of the probability of the existence of extraterrestrial civilization and humanity’s lack of contact with, or evidence for, such civilizations.
The Arecibo message was broadcast into space a single time via frequency modulated radio waves at a ceremony to mark the remodeling of the Arecibo radio telescope on 16 November 1974. It was aimed at the globular star cluster M13 some 25,000 light years away because M13 was a large and close collection of stars that was available in the sky at the time and place of the ceremony.
Euchre or eucre is a trick-taking card game most commonly played with four people in two partnerships with a deck of 24 standard playing cards.

A great many other engineering sub-disciplines are also called upon.
Hillel (הלל) (born Babylon traditionally c.110 BCE, died 10 CE in Jerusalem) was a famous Jewish religious leader, one of the most important figures in Jewish history. He is associated with the development of the Mishnah and the Talmud. Renowned within Judaism as a sage and scholar, he was the founder of the House of Hillel school for Tannaïm (Sages of the Mishnah) and the founder of a dynasty of Sages who stood at the head of the Jews living in the land of Israel until roughly the fifth century of the Common Era.
The second law of thermodynamics states that the entropy of an isolated system never decreases, because isolated systems spontaneously evolve towards thermodynamic equilibrium—the state of maximum entropy. Equivalently, perpetual motion machines of the second kind are impossible.
The Foucault pendulum, or Foucault’s pendulum, named after the French physicist Léon Foucault, is a simple device conceived as an experiment to demonstrate the rotation of the Earth. While it had long been known that the Earth rotated, the introduction of the Foucault pendulum in 1851 was the first simple proof of the rotation in an easy-to-see experiment. Today, Foucault pendulums are popular displays in science museums and universities.
The story of one 10-year-old boy who decided to study judo despite the fact that he had lost his left arm in a devastating car accident.
The boy began lessons with an old Japanese judo master. The boy was doing well, so he couldn’t understand why, after three months of training, the master had taught him only one move.
“Sensei,” the boy finally said, “shouldn’t I be learning more moves?”
“This is the only move you know, but this is the only move you’ll ever need to know,” the sensei replied. Not quite understanding, but believing in his teacher, the boy kept training.
Several months later, the sensei took the boy to his first tournament.
Surprising himself, the boy easily won his first two matches. The third match proved to be more difficult, but after some time, his opponent became impatient and charged; the boy deftly used his one move to win the match. Still amazed by his success, the boy was now in the finals.
This time, his opponent was bigger, stronger, and more experienced. For a while, the boy appeared to be overmatched. Concerned that the boy might get hurt, the referee called a time-out. He was about to stop the match when the sensei intervened. “No,” the sensei insisted, “Let him continue.”
Soon after the match resumed, his opponent made a critical mistake: he dropped his guard. Instantly, the boy used his move to pin him. The boy had won the match and the tournament. He was the champion.
On the way home, the boy and sensei reviewed every move in each and every match. Then the boy summoned the courage to ask what was really on his mind. “Sensei, how did I win the tournament with only one move?”
“You won for two reasons,” the sensei answered. “First, you’ve almost mastered one of the most difficult throws in all of judo. Second, the only known defense for that move is for your opponent to grab your left arm.”
First they came for the communists,
and I didn’t speak out because I wasn’t a communist.
Then they came for the socialists,
and I didn’t speak out because I wasn’t a socialist.
Then they came for the trade unionists,
and I didn’t speak out because I wasn’t a trade unionist.
Then they came for me,
and there was no one left to speak for me.
Every great scientific and engineering triumph in human history has been a slap in the face of technological conservatism—the little ones, perhaps even more so. And yet each new step forward, no matter what the size, is inevitably met with a fresh crop of familiar objections. “Just look at what you have already, and it’s still not enough for you. Where does it end?”
It doesn’t. It never ends. Keep moving or get out of the way."
- Cheyenne: What do you call yourselves?
- Steven: The Pieces of Shit.
- Cheyenne: That's a really good choice.
- Steven: You're fuckin' right it is, yeah! It took us 6 months to come up with it, besides it's exactly the right name for this moment in history.
My sense is that the scientific way of thinking, questioning, some delicate mix of creative encouragement of new ideas, and the most rigorous and skeptical scrutiny of new and old ideas, I think that is the path to the future, not just for science but for all human institutions."
