Language of Life: Levy Walk
How sharks and other ocean predators find food in the big, wide ocean
David Sims from the UK’s Marine Biological Association found that many large marine predators use a search strategy called a ‘Levy walk’. The strategy is formally described by a mathematical equation, but in simple terms, it means that an animal makes several short moves in its search for food, interspersed with a few long ones. The longer the ‘step’, the more infrequent they are.

In practice, using a Levy walk means that searching a smaller area thoroughly before making a long journey to a completely new one, rather than gradually combing across the ocean. It’s similar to someone looking for their keys by focusing on specific corners of a room at a time.
Sims believes that the predators use this strategy because it’s tailored to the distribution of their prey, such as krill, which tends to be highly concentrated in specific areas and scarce over long distances. With patterns like these, a Levy walk gives a hunter a greater chance of blindly stumbling across some prey than a purely random search.

Today in biology the teacher asked “why do chromosomes have to stick together?” And I whispered “because they’re bromosomes” and the guy next to me just about died laughing

Definition of parkour is getting from one place to another in the fastest possible route.

Without breaking your legs/spine/skull.

Having your internals still in one piece by the end of it is an optional bonus.

THE BOY WHO LOVED TO READ
Unknown author
Once, there was a boy who loved to read. He read everything he could get his hands on, and loved going to his favorite book store. One day, the boy realized he had read everything the store had to offer. He confronted the owner, and asked him if he had anything the boy had never checked out. The owner said why, yes, I do, and pulled out a book called “Death”. He gladly sold it to the boy at a discounted price of 50$.
However, he warned the boy, never to read the front page. Well, the boy returned to his house and read the book, and he was content. However, he always wondered, what could be on that front page, it was always in the back of his mind. One day, the temptation was too much for the boy, and he flipped to the very front of the book, and dropped the book in HORROR.
There, in bold print, was MSRP 7.99$

THE TRUTH OF NATIVE AMERICANS BEFORE THE GENOCIDE

Gotta put this on blast.
We never needed a white savior.

I hate this country.

What I learned from this video:

  • 100 million Native Americans died at the hands of white colonists
  • Instead of planting crops the colonists spent their days digging random holes in the ground looking for gold. They started starving and dug up Indian corpses to eat. They took Indian prisoners and forced them to teach the colonists how to farm
  • Native Americans had massive cities with tens of thousands of well constructed houses, intricate water canals and large merchant areas.
  • The Native Americans used soaps, deodorants and breath sweeteners while colonists never bathed or even took of their clothes
  • There was a delousing policy with the mantra Nits create Lice; nits being Native American babies, so their goal was to kill every Indian, including babies 
  • In the 1700’s 80% of the Federal Budget went towards eradicating the Native American population so they could take their developed farmland
  • Colonists leaders went town after town killing men women and children under the approval of George Washington
  • "Pursue Indians to extermination" -Thomas Jefferson
  • California governor (1849-1851): “extermination must continue to be waged until the Indian becomes extinct”

The main factor which prevented Native American extinction was the fact they were used for slave labor. The most prized Native Americans were young girls who were said to be valued for labor and lust (that one white dude in your ethnic studies class that says he’s 1/36th Cherokee?)

In modern times children were forced into Indian Boarding Schools whose goal was to “Kill the Indian in them”. It was federal policy. They were beaten if they used their native tongue, they were forced to dress and style their hair like whites 

This country was literally built on terrorism and mass murder. White people are savage terrorists.

Until, this is taught in schools everywhere- “history class” is merely a racism propaganda course.

last year i was eating in a fancy, large restaurant when i began to hear a rumble and the distant sound of people chanting ‘potassium, potassium’ and suddenly hundreds of people dressed as bananas flood this restaurant chanting potassium over and over and we were trapped there for a very long time because the bananas would not leave and they were everywhere

Many of us have preconceived notions about people’s accents. We find Western European accents—French, British, Castilian Spanish, Italian—relatively appealing, while Asian and Mexican accents are experienced as unintelligible or offensive… if an employee speaks French well and English only moderately well, we aren’t bothered. however, if Filipinos, for example, speak Tagalog to one another at work, the assumptions are that they are purposefully excluding English-speakers, that they are not trying to learn English, and that they don’t care. A mean-spirited quality is attributed to the behavior.

Frances E. Kendall, Understanding White Privilege 

White supremacy doesn’t regard non-white languages as real languages, it regards them as deviant forms of communication reduced to broad ethnic strokes (“Indian”, “Asian”, “African”) that is unacceptable because it is seen as an affront to white/euro hegemony.
