What percentage of children are capable of learning "the math" under ideal conditions and circumstances?

What percentage of children are capable of learning "the math" in practical conditions and circumstances?

What is the distribution of ideal ages for children to learn "the math" in practical conditions and circumstances?

What happens when those ages (for most) don't line up with the various social factors that will contrive to make certain they permanently lose the opportunity to learn "the math"?

Should my children have to wait years to learn it because your children aren't ready yet but the education system can't afford to teach it twice to two separate smaller groups? What if that means pushing it to the point where my children would age out of the education system, and they never get to learn it, even if they'll be better at it then yours will be?

The education system is wrong. You get that right. But what you fail to see is that it can't ever be made non-wrong. What you want out of it isn't the same thing I want out of it. Or that the other guy wants out of it. If we look at how the education system functions, it only ever had political goals. Those have shifted over the years as various factions found new uses for it. At first it was just a jobs program of sorts. And maybe a little ethnic homogenization program. Little snippets of cultural genocide here and there in problematic geographic regions. Then it became a unionized voting bloc. And now it's just a treadmill to keep children busy and stupid so they don't ever quite figure out what was done to them. It's government-funded daycare in an economy that increasingly can never afford for even one parent to be home during the day in the early developmental years.

And it has done all those things remarkably well, and reasonably cheap too. What's broken that you really need to fix? Sure, I'm a little sarcastic there... but why can't you see that this system doesn't have any mechanism that will allow for non-superficial reform? Those with the power to do that don't use the public education system anyway.
One of Grant's failings was trusting too easily. He was broke because he was taken in by a con artist, then developed throat cancer before he could get his feet back under him, and spent his dying months writing out the manuscript by hand because he couldn't do tate to a secretary any more.
The cheap money was stressing the system before the pandemic relief came in and made everything fall over. You can't cut rates unless you are prepared to raise them, cheap money only works as stimulus if you make money more expensive in good times.

If we were more conservative with our monetary policy, then we could have prepared better for the next stress event. At least we could stop things from getting crazy (e.g. the housing market). We've basically forgotten the 90s already.
In comparison to what came immediately before and after, it was pretty good.

>>Pick a random azimuth you want to go. Keep walking while having sun always at the same position and you'll be walking in the straight line.

Not quite. That's a good way to get lost in a hurry.

Let's pick North as our azimuth, right around sunrise in my location in New England. The sun is rising 77° to the right at 06:00, as I face North and start walking.

But the sun moves in the sky, so if I keep the sun 77° to the right of my nose as I walk, by 12:15, the sun is at 167°, and I am now walking due East...

I'll be walking in a curve following your guidance here, not a straight line, and the radius will depend on my walking/riding/sailing speed.

The same failure occurs for the Moon or any other astronomical object other than the polestar.

This is why the invention of portable accurate timepieces was so critical.
This seems especially pertinent in New York TRACON. During busy times controllers there can be sending or receiving virtually nonstop; it's difficult enough even listening for your callsign and getting a word in edgewise.
> Would spending that on other chemistries (ex sodium ion) produce better results?

You are still acting as if investment in one idea somehow precludes investment in another. This entire time, I was stating that we can easily justify vast sums of R&D in many possible ideas. That should include hydrogen, not coming up with a series of excuses to avoid it. Especially considering that hydrogen fuel cells already exist commercially, and are already well past the lab stage (something na-ion have not gone past).

Finally, the words "high likelihood" is not a well defined claim. You can easily adjust your numbers to justify or reject any idea depending on what you personally feel. In reality, we are strongly motivated to pursue many ideas simultaneously and we do not have the luxury of ignoring options.

Yes I just migrated from Jekyll to NextJS.

I agree it’s a terrible idea if you just want a blog. My motivation was to improve my web dev skills and have a low stakes playground to try stuff, since I’m using Next on most of my projects.

You're getting a lot of strong reactions here, so I'll just stand up and say I agree with the point I think you're making, which is that the cavalier attitude some people have towards killing harmless insects is misplaced, especially when interactions can be mitigated easily. I'm not so sure it's as simple as turning lights off, though.

I do not hold the same opinion on disease carrying insects. They, regrettably, must be eliminated where people live. It's unclear which insects op is intending to kill. Around here such a campsite trap would net almost exclusively mosquitoes, which count as disease vectors to my eyes.

No. You don’t owe anything until the coffee is in your hand.

Or until they cancel the transaction.

If you order the coffee, they say “okay that’ll be $2.87”, and you try to pay with cash, they can cancel the order. Poof, no debt.

Now if they drop the check at your table after you’ve enjoyed the cup of coffee, it’s different IMO.
Shutting down the old Soviet reactors definitely makes sense. Small countries maintaining a nuclear industry doesn't make sense. But engineering powerhouses like Germany (or France) maintaining a nuclear capability, and keeping reliable plants operating, is very different.

I'd recommend reading the book Team Topologies [1] - it was well-written and gave me some new ideas for how teams can interact. And it's deeply founded on Conway's Law, including featuring a concept called the reverse Conway maneuver [2].

(Note that the book and the reverse Conway maneuver is also mentioned in the friendly article)

What's your source for "math outcomes are way better in every aspect"? Figuring this out is trickier than it seems. Not only do students vary in demographics, socio-economic factors, and English-learners, but there are also relatively way more children of professors at Berkeley schools than in SF.

Fun fact - in central/eastern Europe algebra starts in 6th grade (kids aged 11-12yo), and we don't have much problem with that.

It has a “guiding principle”:

> Students’ academic success in mathematics must not be predictable on the basis of race, ethnicity, gender, socioeconomic status, language, religion, sexual orientation, cultural affiliation, or special needs.

That’s amazing! While it may be laudable to hope that a math education program could be so strong that socioeconomic status and race make no difference, the rest of this is absurd. There are people with special needs who are at a disadvantage in math. The only way that their special needs would not predict the distribution of their academic success would be to have an implausibly amazing special needs education program, to redefine success, or to hold everyone else back.

SpaceX has sunk enormous sums into building and launching thousands of their own satellites. Roughly one half of all operating satellites.

Their investment dollars up to now have also covered development of their next rocket, with planned capabilities of refueling in space and round trips, including site landings, to anywhere in the solar system, and have a greater lift capacity than the SLS, beyond their current achievements in rocketry.

They also had to, from scratch, develop an organization, build out design, manufacturing and flight control capacities, their own launch facilities including unique water landing platforms.

NASA already had extensive facilities and capabilities, prior to their latest rocket project.

Of course, both NASA and SpaceX were able to leverage NASA's previous experience with rocketry. (I am a fan, not a critic of NASA.)

> NASA reports the official cost of the SLS as $11.8 billion [1]

> NASA estimates will cost $13.8 billion to develop through its first crewed launch in 2024. [1]

That doesn't cover the costs of additional rockets. Which get discarded after every launch.

> each SLS/Orion launch will have a price tag of about $4.1 billion. [2]

When you consider the cost of NASA launches vs. SpaceX launches, there are now between an order or two of magnitudes between them. Which is reflected in SpaceX launch prices. Starship will eliminate the second stage losses, resulting in even cheaper per launch costs.

I cannot think of another time in history where a company has managed to so decisively leave all competition, including major strategic nation-state initiatives, behind.

-- EDIT --

Not sure how I missed the opening paragraph of [1]:

> From its inception in 2011 through the year of its first flight, the Space Launch System rocket program has cost $23.8 billion. The Orion deep space capsule has cost $20.4 billion since the program began in 2006. Related ground infrastructure upgrades cost an additional $5.7 billion since 2012. In total, NASA spent $49.9 billion on these programs between 2006 and their first test launch in 2022.

$49.9 Billion!
It actually wouldn't take much. They were effectively doing this prior to the supreme court swinging far to far to the laissez faire attitude on market power in the 1970's through now. We wouldn't even need to swing back very far to start breaking the monopolists up.
It’s not strange at all if you understand the differences between a private sector union and a public sector one. What’s really strange is how anyone that’s not a member of a public sector union could think it’s a net benefit for society as whole.
> You are still acting as if investment in one idea somehow precludes investment in another.

This is the political reality. Yes we should be doing more.

> I was stating that we can easily justify vast sums of R&D in many possible ideas.

Perhaps we should, I’m not sure that “can easily” applies to spending trillions on R&D.

> That should include hydrogen, not a series of excuses to avoid it. Especially considering that hydrogen fuel cells already exist commercially, and are already well past the lab stage.

Agreed, we should be researching hydrogen for energy storage. And we are. We are also researching other chemistries with different tradeoffs. And a few of those chemistries have become viable as current market products, so they are receiving different kinds of investment to move them from research products to broad implementation.

> In reality, we are strongly motivated to pursue many ideas simultaneously and we do not have the luxury of ignoring options.

Agreed. I have not seen any evidence yet that hydrogen is being ignored as an energy storage medium.
Couple points:

- Canada is an English and French speaking country.

It’s creating a generation of black and brown students that are uneducated and won’t be able to compete against anyone else. It’s the ultimate in racism. Overt racist policies couldn’t be more effective and de-educating these students more than these ”progressive” policies have. Half of Black SF high school students can barely read.

Decades of EXCLUSIVELY PROGRESSIVE policies have lead to this end result. There aren’t any Republican boogeymen you can blame for this damage these policies have created.

I've worked many nights and weekends, but only by my own decision (never on call or firefighting) and usually balanced that by taking time off during traditional working hours.

I don’t agree with this at all. I studied math way past high school and what you learn up until the last 2 years of a standard undergrad curriculum does not even approach what mathematicians do or care about. It’s not even putting you on the PhD track at all, to the contrary, the weird detour into calculus/statistics/non-theoretical linear algebra from an applied perspective sets you back a solid 2 years if you’re following a standard curriculum.

The current math curriculum is about giving people a strong base for using math outside mathematics itself, in case they want to study physics or some other science, or engineering. Mathematicians do not generally give a shit about the computational aspect (it’s not what math is about, generally speaking) which you spend most of your time doing in math curricula until you’re at the point where further studying math suggests you are interested in math itself.

The vast majority of people who struggle in math IME have at least one of two problems: one is they struggle with it and put up some mental barrier of being “bad at math”, the other is they fell behind at some point and the curriculum kept chugging along with no chance for the student to catch up (which just makes the subsequent material fail to stick and confusing). This has nothing to do with some nefarious mathematicians’ agenda and everything to do with the school system not allowing students to progress at different rates based on proficiency.
All Conway’s Law means is that to build a system (from new components, anyway) that work really well together it is very helpful for the builders of those new components to communicate with each other during the process.

This is a fine heuristic, but it can be interpreted in different ways as you see fit. For instance, since I advocate for professional testing (rather than amateur testing that Agilists prefer) I say, by Conway’s Law, that testers should be gathered together in one team, rather than scattered around in little Scrum teams. Testers benefit more by working together than they do by hanging around developers, since only coding testers really can deeply understand the devs and the code, and when they try they simply become junior developers and lose all the critical distance that makes independent testing effective.

By Conway’s Law, the “Whole Team” approach really just coopts testing and isolates testers (like being the only sober guy at a party), and puts the tester under pressure to get along instead of critique the product.

Fowler poo poohs the idea of independent testing in his article, but he is not a professional tester and I think he hasn’t thought this through. The couple of times I met him he was friendly and listened well, though.
