Paper Airplanes

Sam Harrelson on August 14, 2023

I love incorporating paper airplanes into my classroom lessons on dynamics, flight, movement, gravity… the list goes on and on. They’re so applicable to so many scientific principles but also appeal to the curious nature inside all of us that loves to fold and learn…

History of the Paper Airplane: Paper Flight Technology Inspires Drones:

“The magic of a paper airplane is that all of these little flight corrections are happening continuously throughout its flight,” Ristroph says. “The plane is hanging under a vortex that is constantly swelling and shrinking in just the right ways to keep a smooth and level glide.”

Thinking About Screentime

Sam Harrelson on August 13, 2023

I’ve become much more of a book person as I’ve gotten older. Also, notebooks. That would seem quizzical to my younger self that reveled in every new productivity and reading app released on iOS or Android as I combed through blogs, subreddits, and Twitter lists, looking for the latest and greatest note-taking app.

Alas, getting old is interesting.

Screentime is definitely something that’s been on the front of my mind for the last few decades as I’ve welcomed children into this world (including Lily as of August 1!) and young people ranging from 12 to 18 into my classrooms.

I plan to read this book, so I’m using this as a space-saver for myself to return to when I’m done (and in the middle of the school year).

Screentime is a fascinating cultural concept. The amount of “screentime” we actually consume is lower than it’s ever been (no, really). But is the measurement of “time” really what we should be focused on or worried about?

Regardless, my students will still have their devices in the “off” mode, and we’ll focus on the great ideas with our brains, pen/cil, paper, and each other’s voices like we’ll continue to not have devices on during dinners or downstairs time here in our home…

A Different Way to Think About Screentime:

Parents have a hard time when they don’t know something. I’ve written this elsewhere, but I think one of the basic things that underlies a lot of the book bannings and pronoun panics from parent-activists on the far-right is the very simple fact that parents don’t know what their kids do all day. My daughter Maeve is 7, and I volunteered this spring to help with a field trip for her first-grade class. The bus was late, and so I ended up just sitting in her classroom for about 45 minutes while the day went on as usual. Maeve is very talkative, and she loves telling us stories about her day, but it wasn’t until I sat in that classroom that I realized how little I actually knew about what the ordinary beats of that day were like, what the social dynamics were, what kind of job her wonderful teacher — hello, Mr. Diego Fernandez — is tasked with doing.

Reconnecting with Voyager 2

Sam Harrelson on August 7, 2023

Voyager 1 and 2 were launched in 1977 and have, by all expectations, exceeded their missions and then some. I was born in 1978, so I share some sentimental affinity with these two marvels of human engineering. Glad to see we reconnected with Voyager 2 after a few scary days there as it continues its incredible journey outside our solar system.

We’ll be in touch with the two Voyagers until they run out of their power reserves sometime in the 2030s. That will be a sad day. May we all contribute a verse to humanity’s story and the cosmos, much as these robots have done during their time!

I don’t think it’s a coincidence that my daughter was born on August 1, either 😉

NASA reestablishes full communications with Voyager 2:

Voyager 2 resumed communications with Earth after remaining silent for two weeks. At 12:29 a.m. EDT on Aug. 4, the spacecraft began returning science and telemetry data, indicating it is operating normally and remains on its expected trajectory, stated NASA.

The Digital Dark Age

Sam Harrelson on July 27, 2023

Another reason you should be writing in your own space on your blog and notebooks…

Shining a Light on the Digital Dark Age – Long Now:

A false sense of security persists surrounding digitized documents: because an infinite number of identical copies can be made of any original, most of us believe that our electronic files have an indefinite shelf life and unlimited retrieval opportunities. In fact, preserving the world’s online content is an increasing concern, particularly as file formats (and the hardware and software used to run them) become scarce, inaccessible, or antiquated, technologies evolve, and data decays. Without constant maintenance and management, most digital information will be lost in just a few decades. Our modern records are far from permanent.

Arc 1.0

Sam Harrelson on July 25, 2023

I’m excited to see the “1.0” launch of the browser Arc. I’ve been using Arc as my main browser (along with Safari and some Chrome sparingly) on my MacBook, and I have to say… it’s impressive.

Browsers seemingly slipped from the “wow” factor of the internet about 15 years ago after Google finally launched Chrome despite the best efforts of Firefox, Brave, Opera etc to get the mainstream about browsing again. Apps took their place as the way to access the web for most people, and as our main screen sizes shrunk, so did our attention for interesting browser features.

However, I do think we’re at an inflection point and we’ll see interest around concepts such as Arc that will move us away from a centralized app-based future of the web towards further democratization and decentralization of what the internet should mean.

Way to go, Browser Company!

Arc from The Browser Company:

A browser that doesn’t just meet your needs — it anticipates them.

Also, if you head over to the credits page, you can find me there as a long-time tester in the pre-launch phases!

Are You a Subtitles Fan Too?

Sam Harrelson on July 2, 2023

I realized last week while catching up on The Mandalorian that I have been using subtitles so much more recently. I chalked it up to getting older and not being able to hear dialogue as well. Interesting study here…

50% of Americans watch content with subtitles most of the time.

55% say it is harder to hear dialogue in shows and movies than it used to be.

62% of Americans use subtitles more on streaming services than regular TV.

57% watch content in public; 74% of Gen Z do so.

On Notes and Note-Taking Apps

Sam Harrelson on June 14, 2023

I’ve long been a fan of note-taking apps going back to my beloved Evernote in its early beta days of 2007 or so (I still have the t-shirt). I’ve used most every iOS and a slew of Android note-taking apps as well. All have the same promise that I’m looking to fulfill… a place to store things I come across that I don’t want to lose.

We need to forget. But we need to forget safely. That’s why we use note-taking apps.

I recently rediscovered my love of note cards and Zettelkasten while diving into the wonderful app Obsidian. I’ve long used notecards to process good thoughts, bad thoughts, interesting thoughts, and things I need to remember (or forget). I have a huge storage box of them. Somewhere along the way, I let that practice go in favor of more digital means of keeping notes.

But here we are in 2023 and I’m in love with notecards again.

This comment hit home…

Notes apps are where ideas go to die (2022) | Hacker News:

Writing is part of the creative process.

Writing it down helps to solidify an idea into the heap from the stack, maybe even take it from hot storage to cold storage. It allows you to jot it down while it is still fresh and offload it to focus on it later. This is super helpful in ideas, jokes, thought streams, todos, one pagers on some projects, etc. It does help you remember but also allows you to move to the next thing for now.

Writing down ideas is like a sketchbook, ideas/actions/iteration of thoughts both good and bad. It is important to write thoughts down though because how many times have you had a great idea and you are like “I’ll never forget this” and then a while later you are wondering what that was or you entirely move on because life moves fast.

Creatives, writers, comedians, developers, or just projects, are better when writing is involved in ideas to realization of those ideas.

Writing it down and notes is a form of brainstorming. Brainstorming allows ideas to be spontaneous and allows improvisation to get to better ideas. Even writing down bad ideas because somewhere in it is something good.

I use notes apps but more now just a repo (super easy with github.dev everywhere) and notes have easy history that way and you can freely add/remove without feeling like notes are lost. When I use notes apps or even Google Docs, yes they have history but it isn’t as fluid/quick as github for that. The important thing is find something that works for you that makes the barrier to writing it down almost non-existent. It needs to be very easy to write things down in between busy days and to capture these fleeting moments.

It’s a Different Sort of Revolution

Sam Harrelson on June 14, 2023

I don’t think we’re prepared to understand how AI (especially more advanced generative AIs) will impact what we currently consider career jobs… especially for those with advanced degrees.

This represents a stark difference in past societal shifts when physical labor-focused employment and careers were impacted…

Biggest Losers of AI Boom Are Knowledge Workers, McKinsey Says – Bloomberg:

In that respect, it may be the opposite of significant technology upgrades of the past, which often came at the expense of occupations where workers had fewer educational qualifications and got paid less. Many were performing physical tasks — like the British textile workers who smashed up new cost-saving weaving machines, a movement that became known as the Luddites.

By contrast, the new shift “will challenge the attainment of multiyear degree credentials,” McKinsey said.
