Veritasium (1.2) - Why does poop smell bad?

  After all, it's about survival of the fittest. But survival of the fittest what? I mean, most people think of natural selection as being about the survival of the fittest individual? animal? Individual Individual  Individual  Animal,  Animal?  Okay, so it's like an individual.  Yeah.  Which makes sense. I mean, individuals best adapted to their environment have increased odds of survival and therefore a higher likelihood of passing on their genes.  So it follows that each individual should do everything it can to survive and reproduce.  That is, it should be selfish .  But if that's true, then how do you explain this?  Worker bees will sting predators to protect the hive, even though it might kill them in the process.  Female worker ants are sterile, so they can't reproduce, but regardless, they work for the colony for their entire lives until they die.  Monkeys adopt orphans, wolves bring meat to non-hunting members of...

Prof Jonathan Gruber (1.10) - The Equilibrium, Supply and Demand Curve

  We call the point where those two curves meet the equilibrium. The point where supply and demand are in agreement is the equilibrium. That is the point at which suppliers are willing to sell roses at the same price consumers are willing to pay for them. So with 600 roses, 600 boxes of roses or whatever it is the equilibrium price is $3.  Well, it's a rose, So with 600 rose the equilibrium rice is $3. That is, both parties are happy in equilibrium. The key point about equilibrium , as the name implies, as the term equilibrium implies, It's the point where the system has come to rest.. Where both parties are happy with the outcome.  Both parties are happy because it's on the demand and supply curve. Since it's on the demand curve, consumers are willing to pay $3 for 600 roses. They wouldn't pay $4 for 600 roses, but they'd pay $3.  Since it's on the supply curve, suppliers are willing to accept $3 for 600 roses. They wouldn't accept $2 for 600 roses, but...
