I’m about to start a job search and the stackoverflow jobs board seems to have a decent number of positions… most even advertise salary band, which is nice.

> I think science should be limited to scientists The GP asked a question, obviously out of a place of wanting to learn. How else are new scientists produced if we don’t let non-scientists engage in science?

Having been in the military and worked in universities and corporations… I’m skeptical of any large group of people (grew up Catholic too… churches don’t get off the hook here). But again how else do we solve problems except by collective a

Many more examples corporate misbehavior. And yet strong regulations and unions are still some of the best tools we have. (Best does not mean perfect… not being naive.) If you believe in some libertarian ideal of everything being handled by

I know it’s not popular here, but unions are a counterweight to political power of corporations. As professionals we’ve been conditioned to “not talk politics” at work… the one place where you engage most with political decisions. But thank

No idea. My buddy and I have a Phase I SBIR finishing on Friday and I think we’d need a Phase II to even get to the point of having a product. As much as I love being in the fight and taking risks, I don’t know that it’s worth working for p

Ok but in a college algebra class it’s very easy to ask “what is the inverse of the squaring operation?” Not so clear a path to the action of a matrix on the plane. I have successfully discussed this in an advanced calculus class.

I hate to “pull rank” but I have a PhD in mathematics so I’m personally well aware of all the nuances. Again my point is historical/pedagogical. Why should “pair numbers” or “double numbers” be the answer as the OP suggested? It’s not

Sure we can locally visualize a conformal mapping. But in the historical development of complex numbers, or pedagogically in a college algebra class… this would be putting the cart before the horse. Again why would anyone posit that a pair

My point is that we step off the real line to talk about the points where the function vanishes... but what about the neighborhood of the roots where we're plugging complex numbers into the function and not getting a real number as o

> If you called them double numbers or paired numbers nobody would say that. I'm not sure that's true. Just think of solving x^2+k=0. It's clear that for k<0 you get two solutions and k=0 you get one solution. But when

Yes, I've also read The Bell Curve. I'm not sure what any of this has to do with designing an education system. Lots of kids aren't going to be professional athletes, but they still manage to have fun kicking a ball around. T

Yeah I'm not qualified to say precisely why things are they way they are. But I also don't understand how people can look at such a statistic and decide that mathematics teaching cannot contain any inequality based on some high-mi

Exactly. I'm sure you put in a lot of hard work to become Valedictorian! But a lot of other responses seem to take any critique of the system as an attack on their own hard work. Realistically, people like you and I who had a stable up

by dls2016 5y ago
And to put in the work, you need motivation. The existing homogenized K-12 system of mathematics is not very motivating to a lot of students. Hence the inequality.

HN is full if the “homework doers” who scored well and got nice professional jobs. Hence the downvotes.

Most of what you're saying seems reasonable... but then I see a statistic like this: "Black Americans receive about 7 percent of the doctoral degrees awarded each year across all disciplines, but they have received just 1 percent

Isn’t this what we’re seeing? Semiconductors strained leading to rising auto prices? (For example.) What evidence is there that it will radiate outwards at a rate significantly above the Fed’s target for an extended period of time?

How is this different than any other billionaire? Perhaps allowing un-elected people to hoard and control such vast resources is simply incompatible with a democratic society... Why is Bezos allowed to squash a tax to address homelessness?
