Walking New York

by xkcd

Walking New York

Could a person walk the entire city of NY in their lifetime? (including inside apartments)

Asaf Shamir

Like the answer to Paint the Earth, the answer to the first part of this question is pretty straightforward to look up.

But what if it weren't? Can we figure out the answer from things we already know? Let's look at a few ways of estimating it.

First of all, how wide is a street? I've never seen one of those flashing crosswalk countdowns signs start with less than 10 seconds; if people walk at a meter per second, most roads are probably at least 10 meters wide.[1]There's a table from the 1892 World Almanac listing the widths of all avenues and streets in Manhattan, as well as the lengths of all the blocks, confirming that even in 1892 the streets were at least 20 meters wide. I found a copy of the table over at the blog Stuff Nobody Cares About.

Most people wouldn't have trouble walking 10 kilometers (6 miles) in a day. If the city were covered in kilometer-long streets laid down edge-to-edge, with no space between them, you could fit a thousand roads side-by-side in 10 kilometers. That means a person could walk back and forth across an entire 10km by 10km grid in, at most, 3 years.[2]On the streets. You have to add another 3 years for the avenues.

I don't know how many 10 km square swatches it takes to cover New York City, but it's probably not very many.[3]Turns out it's a little more than 1 to cover the land and water. And since NYC has some space not occupied by streets, this tells us that the answer to the first part of Asaf's question is almost certainly "yes"—purely from a geometry standpoint.[4]Another way to come at this calculation is to remember that Manhattan streets are numbered, and you never see four-digit numbers.

Here's another approach: I happen to remember that the US Postal Service employs about half a million people. NYC's population is almost 10 million people,[5]The city itself is about 8.5 million, and the metro area is about 20 million. so almost 1 out of every 35 Americans lives there.[6]I remember seeing some California politician boast that California had 14% of the country's millionaires. But 1 in 8 Americans live in California, so that's pretty close to what you'd expect. If New York also has 1 out of every 35 postal employees, that's about 15,000 people.

If all those employees were letter carriers, and they visit every address in the city every workday, that would mean it takes a total 15,000 x 8 hours = 14 person-years to traverse the city—much less than a lifetime! Since lots of postal employees are not letter carriers, and real letter carriers stop frequently, this estimate is probably still much higher than the reality.

Another way: Imagine that each person lives alone in a square room measuring 10 meters by 10 meters, which is about the size of a typical two-bedroom apartment. Furthermore, let's assume that everyone's apartment is on the ground floor with at least one side facing a street. In that case, at a walking speed of 2.5 mph, it would take only 2.4 years to walk past every apartment—which Wolfram|Alpha helpfully points out is roughly 1.4 elephant gestation periods.

Any way we come at this problem, it looks like the answer is "yes"—you can walk down all the streets in New York City. And, indeed, it turns out there are 6,074 miles of road in NYC, which would take a total of a little over 100 days of walking.

Now, what about the second part of Asaf's question—walking through all the apartments?

This one is trickier. As a rule of thumb, a household is overcrowded if it has more people than rooms.[8]There are a bunch of definitions, but But at the same time, most households don't have more than two rooms per person. Let's assume all households have 1.5 rooms per person.

Let's assume it takes 20 seconds to get from the door of a room to the door of the next non-visited room. (Most of the time it will be much less, but sometimes the next non-visited room is on another floor or down the stairs, so it's good to give ourselves some extra time.)

If it takes 5 seconds to walk into a room and back out, then you can visit every room in New York City in 10 years. Even if you only visit rooms for eight hours a day, that's totally plausible to fit into one lifetime.

However, a word of warning to Asaf:

Under NY Penal Code §104.15, entering a dwelling without permission is a class A misdemeanor punishable by up to a year in prison.

So while it might take only 30 years to visit every apartment in New York City ...

... it could take you 2,000 millennia to serve out the resulting prison sentence.

11 Books By CEOs That Will Teach You How To Run The World

by Drake Baer

Sophia Amoruso, Nasty Gal, hi-resBusiness books are notorious for being loaded with MBA lard, trotting out "key takeaways" like "take risks," "build a great team," and "don't be afraid to fail." 

But the ones worth reading ditch the platitudes in favor of instructive anecdotes — which is why they so often come from execs who have lived through it. 

From fashion startups to automotive empires, here are the best leadership books from people who have led their companies to success.

"The Hard Thing About Hard Things"

What is the hard thing about hard things? That they don't have a formula, says Ben Horowitz.

"Hard things are hard because there are no easy answers or recipes," he writes. "They are hard because your emotions are at odds with your logic. They are hard because you don’t know the answer and you cannot ask for help without showing weakness." 

Horowitz, now one of the most sought-after investors in the game, used to be CEO of software management company Opsware before it was acquired by HP for $1.6 billion. 

Bonus: Horowitz shows off his ridiculously extensive knowledge of rap lyrics — quoting Kanye West and DMX before the close of the opening chapter.

Disclosure: Marc Andreessen, co-founder of Andreessen Horowitz, is an investor in Business Insider.

"My Years with General Motors"

Alfred Sloan was the CEO of General Motors from 1923 to 1946 — when the car company was arguably the most important organization on Earth. 

More than your average business memoir, the book is a distillation of Sloan's experiences and thoughts around how to steer a massive organization. It serves as a treatise on decentralization and the structure of the modern corporation.

Coauthored by Jason Fried, the cofounder and CEO of Basecamp, "Rework" is a spare startup manifesto. 

While everything in the book might not apply to you — Fried's company has remained at a tiny 37 members while staying profitable — it's useful for the contrarian mirror it provides. After reading it, you'll scrutinize every meeting request that crosses your desk.

Solvent-annealing is found to be an effective method to increase the grain size and carrier diffusion lengths of trihalide perovskite materials. The carrier diffusion length of MAPbI3 is increased to over 1 μm. The efficiency remains above 14.5% when the MAPbI3 thickness changes from 250 nm to 1 μm, with the highest efficiency reaching 15.6%.

A Universal Procedure for the [18F]Trifluoromethylation of Aryl Iodides and Aryl Boronic Acids with Highly Improved Specific Activity

by Dion van der Born, Claudia Sewing, J. (Koos) D. M. Herscheid, Albert D. Windhorst, Romano V. A. Orru, Danielle J. Vugts


Herein, we describe a valuable method for the introduction of the [18F]CF3 group into arenes with highly improved specific activity by the reaction of [18F]trifluoromethane with aryl iodides or aryl boronic acids. This [18F]trifluoromethylation reaction is the first to be described in which the [18F]CF3 products are generated in actual trace amounts and can therefore effectively be used as PET tracers. The method shows broad scope with respect to possible aryl iodide and aryl boronic acid substrates, as well as good to excellent conversion. In particular, the [18F]trifluoromethylation of boronic acids was found to outperform [18F]trifluoromethylation reactions of halogenated aryl precursors with regard to conversion, reaction conditions, and kinetics.

Thumbnail image of graphical abstract

A quality label: Tracers for positron emission tomography (PET) with a [18F]CF3 group directly attached to an arene were synthesized with improved specific activity by the trifluoromethylation of aryl iodides and aryl boronic acids with [18F]trifluoromethane (see scheme). In particular, the trifluoromethylation of aryl boronic acids proceeded rapidly under mild reaction conditions, thus making this method highly suitable for PET-tracer production.

باید سرم را گرم کنم به یک کاری که فکر نکنم به چیزی که نمی‌خوام بهش فکر کنم. باید چیزی بنویسم تا از چیزی که نباید بنویسم ننویسم. یک کار خیلی مهم دارم که انجامش موعد تحویل دارد و خوشبختانه یا متاسفانه ترجمه و بازنویسی چند داستان خودم است. داستانهایی که کلمه به کلمه‌اش …

برای سرگرم کردن خودم و فرار از کلمه‌های خودم، هربار که می‌روم دستشویی سوگ مادر شاهرخ مسکوب به کوشش کامشاد را می‌خونم. واقعا روش خوبی را برای سرگرم کردن خودم انتخاب کردم. کتابش در این حال من کاربری مثل روضه برای بدحالان را دارد. برای سوگ کسی سوگواری می‌کنی که نمی‌شناسی و اشک می‌ریزی چون رویت نمی‌شود برای درد خودت اشک بریزی. درد تصویر شده در کتاب یک درد موجه است که می‌شود برایش بی‌هیچ سرزنشی گریه کرد. کتابش سر و چشمم را گرم می‌کند. جوری دارم اشک می‌ریزم که مادربزرگم برای تیر گلوی علی‌اصغر می‌ریخت. سوگ مادر نشد، فکر کردم دستورالعمل تامین برق به مشتری‌های مستقل پرمصرف در ایالت ایلینوی رو بخوانم که باید فردا خلاصه‌اش را برای همکاران بفرستم. این بهترین سرگرمی و منحرف کننده‌ترین متن برای ذهن کلید کرده من خواهد بود. یک جزوه چهل صفحه‌ای است که در هرپاراگرافش بیست بار توضیح داده منظور از “مشتری برق” و “تامین کننده برق” چیست. چرا نمی‌فهمد من که الان صفحه بیست و یک رسیدم حتما دیگه متوجه شدم مشتری کیست دکل کجاست. این چیزهای طولانی با تفسیر اضافی را وکلا می‌نویسند که بعدا حرف از توش در نیاد. بعدا درنیای بگی که  نامفهموم بود. خوندن متن این شکلی ساعت یازده شب خسته‌ترم می‌کند. بر می‌گردم سر داستان.و ترجمه و بازنویسی “از پله‌ها که بالا آمدی…” نفس خودم بالا نمی‌آید. عکس پله‌ها دسکتاپ لپ‌تاپم است. همه پنجره‌ها را می‌بندم و پله‌ها را نگاه می‌کنم. باید در متن انگلیسی اضافه کنم از پله‌ها که بالا آمدی، نفس من دیگر هیچوقت بالا نیامد. دوباره دارم همان کاری را می‌کنم که قول داه‌ام نکنم. کتاب خودم را می‌بندم و برمی‌گردم سر سوگ مادر :

“… هوا سنگینی می‌کند و به دشواری نفس می‌کشم. او زمین و آسمان من بود”

سوگ مادر – ص سی و دو

The Library Bookshelves!

by Jenny at LGN
If you've been reading LGN for practically any amount of time, you probably know that I love me a good bookshelf! In the past we've used a series of IKEA bookshelves to house most of our books (here's a link to the DIY arched version and the faux-built-in version). When we moved to this house though, I knew we were going to invest in something special for our library built-ins. I am SO happy with how these turned out! The shelves are pretty much the first thing we see when we walk in the door and they make me smile every time.

 photo classy4.jpg

 photo classy3.jpg

I hired a local company called Classy Closets to build and install the insanely huge shelves (they are over 16' tall!). I learned about the locally-owned company first when I was helping my friend Caitlin Wilson work on a show house for the Street of Dreams in Gilbert. Show homes are a great way to discover local companies and I saw Classy Closets' work and was super impressed.

They were wonderful to work with them from the get-go. They have amazing in-house designers that can take care of everything if that's what you need/want, but they also love to collaborate with designers. They also offer trade pricing or commissions, which ends up being really helpful for big projects like this one, though I will say their pricing is incredibly fair for the great, fast work they do. And actually, Classy Closets is offering a huge give away right now for a $2000 worth of custom cabinetry (they do everything from closets to kitchens)!

 photo KomendaLibrary.jpg

So the basic process was I came up with a few drawings and then worked with their production designer to finalize the dimensions and the plan. There were some pretty big tweaks to what I initially wanted because of the vintage library ladder I was asking them to incorporate in the design. The design team was amazingly detailed and careful about the ladder and how and where to install the rod to make the ladder run as smooth as possible.

 photo vIMG_4467.jpg

Let's back up a little though and savor the project reveal! :) If you'll remember, we had a big empty wall here before. We pulled off the old moulding, had an electrician move the wiring up to where the library lights would be, patched the walls and holes with drywall mud, and then primed and painted the whole thing the color of the bookshelves (Ben Moore's Chantilly Lace).

 photo vIMG_4429.jpg

 photo IMG_5110.jpg

Once the shelving design had been finalized, it only took a couple of weeks for the Classy Closets crew to build the cabinetry. The installation took almost two full days for an entire team though! This was a huge project and they were wonderful craftsmen. I couldn't have been happier with the work they did - clean and efficient.

At the end of the second day, the library ladder track was installed. I chose an iron rod to match the hardware on the rollers of the ladder. I thought about doing brass to match the lighting (which was a sale find at Restoration Hardware) and the large ring pulls (which are from Liz's Antique Hardware), but I like how the metals and finishes mix.

The ladder, which was a $250 Craigslist find (apparently inherited from a famous race car driver in California? Here's the back story there.), runs as smooth as butter. It's hard to not hop on for a ride a few times a day! :)

 photo classy8.jpg

It's pretty amazing that we have all of our books in one place finally. Even in Brooklyn, we ended up having to store some books in other rooms. But having this much storage space is completely amazing. 

 photo classy5.jpg

We did my trick of organizing by genre and then very loosely by color. And then I just added in a few little containers here and there to break things up a bit.

These built-ins are such a big part of our home now. We all love spending time in the library. It feels homey and cozy and comfortable. A big thank you to Classy Closets for being so generous to me with their time and with their designer discount. I am happy to have found another great local resource! And locals, don't forget to enter the $2000 master closet redo give away here.
