    You want to know why Kyrsten Sinema travels in GOP circles? It’s because in under 5 years, she has increased her net-worth to over $11M from a net-worth of over $32K. She was paid a hell of a lot of money to sell out.

  2. CSK says:


    I’m not defending Sinema, but isn’t “go to Congress and become a multimillionaire” pretty standard?

    For years industrial companies in southern California used the coast as a dumping ground for toxic chemical waste, including DDT. Decades later, scientists have found that the pesticide remains in high concentrations on the ocean floor and has never broken down.

    The gift that keeps on giving.

    Nearly two years after the discovery of tens of thousands of barrels of waste off the coast of Los Angeles, a scientist working on the issue shared this week that the chemical is still spread across a massive stretch of the seafloor, the Los Angeles Times reported.

    “We still see original DDT on the seafloor from 50, 60, 70 years ago, which tells us that it’s not breaking down the way that [we] once thought it should,” David Valentine, a UC Santa Barbara scientist, said. The LA Times reported that the contamination covered an area of seafloor larger than the city of San Francisco. “And what we’re seeing now is that there is DDT that has ended up all over the place, not just within this tight little circle on a map that we referred to as dumpsite two.”
    In late 2020, a report from the LA Times told the story of how LA’s coast became a dumping ground for DDT, revealing that as many as half a million barrels could still be on the sea floor, prompting Senator Dianne Feinstein to ask the EPA to take action.

    A two-week survey, conducted in 2021 by a team from the Scripps Institution of Oceanography at University of California, San Diego and the National Oceanic Atmospheric Administration, using seafloor robots, sonar acoustic imagery and data helped reveal the scale of the issue, finding more than 25,000 barrels. Scientists identified more than 100,000 manmade items across the entire survey area.

    Scientists’ most recent analysis has found that the most concentrated layer of DDT is roughly 6cm deep in the sediment, the Times reported.

    @CSK: Seems to work that way, tho I think it usually takes a little longer than 5 years.

    Rep. Gerry Connolly

    If you listened to Republicans this morning, you’d think they slept through the Trump years.
    Secretary Blinken was before @HouseForeign today. I took the chance to correct the record. Turns out the Trump Administration left quite a mess for him to clean up.

    Two New Orleans high school seniors who say they have proven Pythagoras’s theorem by using trigonometry – which academics for two millennia have thought to be impossible – are being encouraged by a prominent US mathematical research organization to submit their work to a peer-reviewed journal.

    Calcea Johnson and Ne’Kiya Jackson, who are students of St Mary’s Academy, recently gave a presentation of their findings at the American Mathematical Society south-eastern chapter’s semi-annual meeting in Georgia.
    As mentioned in the abstract of Johnson and Jackson’s 18 March mathematical society presentation, trigonometry – the study of triangles – depends on the theorem. And since that particular field of study was discovered, mathematicians have maintained that any alleged proof of the Pythagorean theorem which uses trigonometry constitutes a logical fallacy known as circular reasoning, a term used when someone tries to validate an idea with the idea itself.

    Johnson and Jackson’s abstract adds that the book with the largest known collection of proofs for the theorem – Elisha Loomis’s The Pythagorean Proposition – “flatly states that ‘there are no trigonometric proofs because all the fundamental formulae of trigonometry are themselves based upon the truth of the Pythagorean theorem’.”

    But, the abstract counters, “that isn’t quite true”. The pair asserts: “We present a new proof of Pythagoras’s Theorem which is based on a fundamental result in trigonometry – the Law of Sines – and we show that the proof is independent of the Pythagorean trig identity sin2x+cos2x=1.” In short, they could prove the theorem using trigonometry and without resorting to circular reasoning.
    “We have really great teachers,” Jackson said to WWL during an interview published Thursday.

    I should say so.

    @CSK: It didn’t used to be. I’d like to know how she’s earning at that level–speaking fees? It sure AF isn’t her selling her used sh!t on Ebay or whatever that was.

    I’d like to return this morning’s snow delivery in PDX. This isn’t the size or color I ordered, and the delivery was late.

  9. CSK says:

    Especially since she has such execrable taste in clothing and shoes.

    @OzarkHillbilly: @Jim Brown 32:

    I’m sure these two young women did have remarkable teachers, but what they accomplished takes super intelligence, initiative, and commitment. Brava.

  13. OzarkHillbilly says:

    @Jim Brown 32: @CSK: And teachers and families to push them and support them. It took a lot of time and effort to accomplish this feat, even if it doesn’t pass peer review. Given the opportunities, they have bright futures ahead of them.

    But trigonometry is reasoning about circles (and triangles)!

  15. CSK says:

    Just triangles, I think.

  16. Kurtz says:


    Unit circle?

  17. Kurtz says:

    I googled something trivial in the form of “x vs. y“. It was unrelated to guns. But one of the results was from I didn’t click, but I assume it is a forum dedicated to the namesake rifle. My brain surfaced questions:

    Are disputes on gun forums less contentious because the presence of a bunch of gun enthusiasts lowers the temperature?

    Are there fewer trolls on such sites, because forum users are likely to be armed and probably willing to use weaponry?

  18. CSK says:

    The circles are always made of triangles to demonstrate angles, right? But yeah, they’re circles.

  19. Gustopher says:

    @CSK: They go hand in hand with unit circles, circles that are defined by the points of a triangle, etc. All your angles, sines, cosines and tangents. The triangle looks like the star of the show, but it’s all circles hiding behind the triangles.

    Wikipedia’s first image for trigonometry… unit circle with a little triangle in it.

    “Are there fewer trolls on such sites, because forum users are likely to be armed and probably willing to use weaponry?”

    Its the internet. Like many internet sites they argue over arcane/trivial stuff and (almost) everyone is a know it all so it can get heated. If you look around you can find some that are helpful on gun safety and usage issues. You will usually get booted if you try to suggest there are places and times where guns are not appropriate or guns might be related to gun deaths.



  21. Kurtz says:



    I wasn’t entirely serious, but it’s cool to get an a peek inside a place I am unlikely to explore.

    I also wondered what would happen if someone went in to argue in favor of gun control. So, your post contained a bonus.
