Yesterday’s #SB5 conflict is an opportunity to talk about the algebra of sets. (Commonly understood through Venn diagrams.)

http://api.ning.com/files/p6R5OhkiVDBcmEzX841dbhLKxY3D9V44AZx*59PqE2CW5Y4azhNcRaG37F65Wu-OBRzSfiAHUCWMmFGbRBhMBZ**lZT5yNjH/stephenwildish04.jpg

The algebra of sets is the way ∪, ∩, , and some composite operations work. These words are useful for reminding yourself to logically separate things that are logically separate.

The relative complement of A (left circle) in B (right circle):
A^c \cap B~~~~=~~~~B \smallsetminus A

For example:

  • Not all feminists are women.
    image
    Feminist ∩ ∁{Woman}
  • Not all women are pro-choice.
    image
    ∁{Pro-Choice} ∩ Woman

Sets can overlap in different ways.

they’re facing each other in court over a rebranding accusation. They’re locked in a legal and public relations fight in the United States over a plan to change the name of the toxic and healthy sweeter, high-fructose corn syrup (HFCS).

On statistical chart-making: All of the interesting information is contained on the left-hand scale numberings. But that information is de-emphasised in the presentation.

Why the scientists aren’t combining data from two experiments to get 5-sigma evidence (= “proof”) for the Higgs boson

The Higgs field was postulated nearly 50 years ago, the LHC was proposed about 30 years ago, the experiments have been in design and development for about 20 years, and we’ve been taking data for about 18 months. Rushing to get a result a few weeks early [would be dumb].


The reason we have two experiments at the LHC looking for the Higgs boson is because if one experiment makes a discovery then the other experiment can confirm or refute the discovery. This is why we have both D0 and CDF, both Belle and BaBar, both ATLAS and CMS, both UA2 and UA1

[T]his disparate level of penalties between the exchange (stiff penalty) and repo (basically no penalty) is precisely the play Deutsche Bank AG did in their Bobl squeeze in March 2001.

They simply didn’t return the bonds they had reverse repoed on time and said: “Whatchu gonna do, b*tch? I’ll tell you what you’re gonna do: Nothing. So shut up and pay up on these Bobl Futures.”

Rumors had it they made like 50 million on that one. Not bad for 1 week of work.

What I sensed was that while the laws of supply and demand governed everything on earth, the easy money was in demand—manufacturing it, manipulating it, sending it forth to multiply, etc. As a rule of thumb (and with some notable exceptions), the profit margins you could achieve selling a good or service were directly correlated to the total idiocy and/or moral bankruptcy of the demand you drummed up for it.


This was easier to grasp if you were in the business of peddling heroin, Internet stocks, or celebrity gossip; journalists, on the other hand, [did not] understand … their role in this [charade].


In the past, newspapers had made respectable margins selling a non-inane product largely because people had little choice but to herald their sublets and white sales alongside the journalists’ tales of human suffering/corporate corruption/government ineptitude.


The times were prosperous enough that much of the print media even chose to abstain from taking a share of the demand-creation campaigns of liquor and tobacco brands…. Indeed, journalism … was about delivering important information about the world—information … democracy … needed, whether [people] knew it or not.


That journalism’s ability to deliver that information—to fill that need—ultimately depended, to an unsettling degree, on the ability to create artificial demand for a lot of stuff that people didn’t actually need—luxury condos, ergonomically correct airplane seats, the latest celebrity-endorsed scent—was an afterthought at best, at least in the newsroom.
