The washing machine was a massive labor-saving innovation that massively changed the way humans live.
We need not to back to the days hand-wringing clothes to achieve climate goals — climate abundance (in infrastructure and technology) is both possible and better than austerity.
I urge degrowth & other climate action researchers to keep in mind that all extraction adds damages to people & ecosystems somewhere, & challenge them to rise above techno-modernist ideology to envision radical alternative ways of organizing our lives & societies.

I'm gen Z (born 2000) and I'll happily defend the phone-based life. I was adopted in my teens to an abusive family in the deep South. Access to the Internet and social media allowed me, as a transgender queer woman, to find community when I had none around me.

It is! I don't know much about physics but I have a MS in data science/stats and I'm working part time on my second master's in mathematics. Just need to spend some time hitting the books on physics concepts😅
@economeager
Having studied both stats and cooking, I can say over-reliance on cookbook methods leads to poor results.
I was always rather inspired by Hirotugu Akaike's dictum to make "statistical thinking as the science of creative thinking."
Fun fact, Solomon Kullback and David Leibler referenced the idea of sufficient statistics ('the criterion of sufficiency') in their article introducing what is now known as KL Divergence, "On Information and Sufficiency" in the Annals of Mathematical Statistics.
The idea of a sufficient statistic is one of the most powerful ideas that I somehow missed in my academic education even though I took a fair amount of statistics.

You know, there's no greater indictment of The Atlantic than the fact that all its writers are like this.
Elitely educated at some of the country's finest institutions, acting like sneering at 'liberals' and coastals makes them much different than the targets of their jeering.
Consider how many liberals of the family-having age view children in bars, restaurants, coffee shops, or public spaces as a gross imposition that detracts from their “freedom” to enjoy their espresso martinis. Many think of kids as a burden rather than the future of society. 4/

This is a map of all properties in Montgomery County, most of which are multifamily townhomes, duplexes, and condos.
@alaina_pitt
's map is single family homes of the type that you were advocating.
My experience emailing professors is that most would send back emails like:
"from james.lastnane

Sent Saturday, 2:17AM
ok sure lol

In the category of “I wish it didn’t have to be said but it does”, here are 10 pieces of advice for emailing your professor (or other professionals):
1. Kick the email address from high school

@alaina_pitt
No you didn't, you posted a map consisting almost entirely of multifamily housing.
These "little houses" that you claim are "modest and cheaper" (i.e., <$400k) simply *don't exist* anywhere except your misconceptions.
Any professor who bans laptops in their class inherently creates a problem for disabled students.
Living with a paralytic condition, I often did take class notes with fountain pen and paper, but using a laptop with text completion software was helpful during paralytic episodes.

@alaina_pitt
Supply in Montgomery County is massively constrained. These $400-600k homes already sell for $30-50k over listing.
Even if — a big if — the new duplexes are marginally more expensive than older housing (doubtful), they provide some demand slack to new buyers of said SFHs.

By creating such rules, professors inherently create the conditions where disabled students are singled out, forced to beg for their needs, and envied by other students for their devices.
I refused to study under any professor who banned laptops, as did other disabled students.

In region after region, we see arguments that removing single family homes will cause an onslaught of luxury developments that nobody can afford.
And in region after region, this onslaught never actually occurs — it's just needless fearmongering from entrenched interests.
@bayesianboy
Reminds me of Herbert Simon's account of trying to mathematize the social sciences, that when working with economists at the Cowles Commission he sought to use "physicists' mathematics or engineers' mathematics" as a "language of discovery" rather than a "language of proof."

Comment on statistics: for those with incomes, the median income is actually $47,960 for all workers and $60,070 for full-time, year-round workers as of 2022 in the Census Current Population Survey. In 2022 CPI-U-RS Adjusted Dollars, it's been above $34k for 15+ y/os since 2015.

There are no $400k starter single family homes in Montgomery County — a fact I know intimately as a first-time homeowner here who bought my townhouse back in March.

This plan provides the opportunity for neighborhoods to adapt to their constraints better than the current land use regime.
Our current zoning does not allow for our communities to adapt and bolster their infrastructure, which is why changes like these are needed.

True, I've known quite a few quant-inclined fruity trans folks go to the polytechnics (in CA and MA)
My dear friend

@AaronDrol
@alaina_pitt
These are separate problems of education and transportation that have their own solutions.
You want a zoning reform bill to address every issue, which is facially absurd. We can start by giving communities the tools to address those issues – this plan provides one such tool.
@economeager
That experience had many of its own downsides (tiger parenting is the worst). The one thing that always stuck with me is the idea that you have to ask the 'dumb' questions because the job is being good at the subject, not looking good in the eyes of others.
@AaronDrol
@alaina_pitt
New duplexes in the few areas they're allowed, leading to greater returns on luxury developments near some of the nation's highest income + wealth areas is not the argument you think it is.

I did half-seriously tell my current partner "I don’t accept Zermelo-Frankel" on the first date! (I like von Neumann-Bernays-Godel because classes are fun and for elegance reasons)
It did work, but it does help she's a theoretical physicist.
The movement to eliminate algebra access for middle schoolers in California was based on a failed educational theory — thankfully the state has finally rejected this needless experiment driven by ideology and bad science.
@AaronDrol
@alaina_pitt
This isn't eliminating single family homes, in fact, single family housing does and will continue to exist.
But it will remove the needless supply constraints provided by single family only zoning by enabling greater choice for property owners and buyers.

Chicago is great and alumni of my alma mater (Northern Illinois) are active in the arts scene.
The art itself is written into the skyline, with famous architects' work like Jeanne Gang, Helmut Jahn, Louis Sullivan. Go out further into Oak Park and you get Frank Lloyd Wright.
Also, the science behind such calls to ban laptops is incredibly mixed:
"Overall, results do not support the idea that longhand note taking improves immediate learning via better encoding of information."
@AaronDrol
@alaina_pitt
Supply and demand dynamics.
New construction will have to compete with listings of single family homes, other new developments, and preexisting multifamily housing, a turbulent competitive process that will result in long-run market clearing prices near market leaders.
@AaronDrol
@alaina_pitt
This isn't going to happen overnight - there will be cases that some luxury developments will pencil in better than other developments, I grant you.
This won't solve every problem, but it does a heck of a lot more towards addressing the issue than your preference of scarcity.
@AaronDrol
@alaina_pitt
Well, I think that construction costs are hard to forecast over 20-50 year cycles.
The 07-09 recession destroyed a lot of capacity for home builders, the question of costs you're asking about is for a market that doesn't even exist yet.
@AaronDrol
@alaina_pitt
I agree, one size fits all is not appropriate!
Which is why I support the expansion of the missing middle and reducing single-family only zoning, because neighborhoods will have the ability to adapt for "a community as big and diverse as MoCo."
@economeager
Also professors could also tell you which books and articles to look it up in to get started on looking it up!
Looking up the literature is 10x easier when you have someone who can tell you "Box et al wrote about that, you should look at Chapter 13* and see."

I took a technical degree, get paid along the lines of IT personnel, make a decent salary cleaning CSVs and helping nontechnical folks with Excel/basic stats.
A 9-5 job with medical and dental, that sure beats working outside in the heat.
Best practices are organizing the mess of Excel spreadsheets that came before you, and building a SQL database.
For most problems, people just want a readable Excel spreadsheet and linear regression is more than good enough.
Fundamental stats, esp for surveys, is very helpful.

My understanding is that finance in general tends to select for personalities in the competition for clients and funding, and having been successful in one specialized form of quantitative finance he then tried to apply his insights in the more general case.
With varied results.
Reading Silvanus P. Thompson's Calculus Made Easy and Haskell Curry's Outlines of a Formalist Philosophy of Mathematics at 11, the former extremely intuitive to my young mind and the latter still challenging to me as an adult, prepared me for studying the higher mathematics.

Two comments:
1- Replications of Mueller and Oppenheimer have led to mixed results, and certainly less definitive conclusions than the original paper.
2- Banning laptops is a disability problem, students who rely on them for physical and cognitive disabilities are singled out.
I'm a high school dropout who got my GED and did my bachelor's at a regional commuter university.

Freeing land from needless single-family only zoning requirements inherently creates a greater market for new builders, contractors, suppliers to provide services. Like the ADU market for contractors in Northern California, demand resulted in additional supply.

And the objective of this plan isn't to create affordable housing — we already have initiatives like the APAH developments in Silver Spring — it's to solve the missing middle of townhomes, condos, and duplexes that's desperately needed here.

Eventually every political-economic system of exchange can be abstracted down to some sort of spreadsheet-ing and linear programming, so Excel will always be desperately needed no matter what the political ordering of society is.

My intuition about international is tending towards large exchanges, and of those exchanges: UK has a passive forward p/e discount, the CAC40 might as well be used to teach Granger Causality against the S&P, and many internationals are seeking to list in the US anyhow.
