    the name seems to be an unfortunate choice that stems from their historical usage as “a means to an end”. i.e, they were first used as part of a method to find some solutions to cubic equations. this method would require algebraic manipulations of complex numbers, but the ultimate goal was to discover a real root. the complex roots would be discarded once a real root was found (if it existed).

    the wikipedia article attributes the name to Descartes:

    … sometimes only imaginary, that is one can imagine as many as I said in each equation, but sometimes there exists no quantity that matches that which we imagine.

    which i think helps to highlight how skeptical the people at that time were about the existence of the “imaginary” numbers.

    source: memories of my first complex analysis class, and https://en.wikipedia.org/wiki/Complex_number#History

    i’d strongly recommend reading the history section of that wikipedia page to anyone interested in the topic, it has some pretty fun history













  • everything you said is true. i just wanted to add something to the suicide point: owning a gun has been tied with an increased risk of suicide. source

    here’s a quote from the link that i think gives a good summary of the problem:

    “Suicide attempts are often impulsive acts, driven by transient life crises,” the authors write. “Most attempts are not fatal, and most people who attempt suicide do not go on to die in a future suicide. Whether a suicide attempt is fatal depends heavily on the lethality of the method used — and firearms are extremely lethal. These facts focus attention on firearm access as a risk factor for suicide especially in the United States, which has a higher prevalence of civilian-owned firearms than any other country and one of the highest rates of suicide by firearm.”






  • that’s not the full story though. according to the NIH, the US government spent over 30 billion dollars on the covid vaccines.

    and this is not unique to the covid vaccine. here’s a source with two particularly damning quotes:

    “Since the 1930s, the National Institutes of Health has invested close to $900 billion in the basic and applied research that formed both the pharmaceutical and biotechnology sectors.”

    and

    A 2018 study on the National Institute of Health’s (NIH) financial contributions to new drug approvals found that the agency “contributed to published research associated with every one of the 210 new drugs approved by the Food and Drug Administration from 2010–2016.” More than $100 billion in NIH funding went toward research that contributed directly or indirectly to the 210 drugs approved during that six-year period.
