Neil deGrasse Tyson Accessory to War

Spread the love

Accessory to War: The Unspoken Alliance Between Astrophysics and the Military by Neil deGrasse Tyson and Avis Lang is a good and interesting book, and I recommend it.

This is not a book that fully explores the alliance and overlap between war and makers of war on one hand and science and scientists on the other. Authors Neil deGrasse Tyson and Avis Lang focus on one part of that relationship, the link between astrophysics and related disciplines (really, astronomy at large) and the military.

Even as I recommend Accessory to War: The Unspoken Alliance Between Astrophysics and the Military, which I do, I want to broaden the conversation a little with a couple of thoughts about the relationship, from my own experience. Then, I’ll give you my strident critique of the book (there is One Big Problem), and then, again, tell you to buy it

Back when I was working in or near the Peabody Museum, in Cambridge, the museum’s assistant director, Barbara Isaac, hired me to work with the NAGPRA database. NAGPRA was the North American Graves Protection and Repatriation Act. Ultimately, large swaths of the Peabody Museum’s collection would be turned over, or some other thing done to it, as per the wishes of the various Native American groups associated with that material. Most of the work had already been done. But, Barbara is a meticulous person and wanted to make sure the dotting of each i and crossing of each t was double checked. So, I was one of two people charged with going over the printouts, on that old green and less green striped paper, bound in large blue cardboard books. Each line (or two) was an item or collection of items, with notes, and an indication of what was going to happen to the material. There were just a few options, but the basic idea was this: An item listed was either going to be returned to a tribal group, or not. My job was mainly to look at stuff that was not going to be returned and, given my ongoing scan of what was going to be returned, and my knowledge of North American prehistory, ethnography, and archaeology, to earmark things that said “do not return” but where maybe we should be returning it. So, for example, after noting that a particular South Dakota Lakota tribe would have this, and that, and this other, soapstone tobacco pipe returned to them, when I saw that the ninth pipe on the list, several lines down and all by itself, is labeled to not be returned, I’d earmark that. Nearly 100% of the time, that ninth pipe was just something that nobody wanted, or it didn’t really exist (not all museum databases are exactly accurate). But, it would be earmarked.

Many items on the list had information as to how the item had originally gotten to the museum.

Many, many items, especially items taken from Native Americans living in what was the frontier between about 1840 and 1900, were taken by medical doctors who, as we all know, also stood in for naturalists, or some kind of traveling scientist, on military and quasi military expeditions (Like Darwin).

And many of those items were taken for use as medical specimens.

We initially learned that Native Americans have a particular blood type because, in part, of studies done on blood stains on shirts of slain warriors, collected after various battles with the US Army units accompanied by such scientists. There are a few famous cases of Native American bodily remains, mostly but not all skeletal remains, sitting in the anatomy teaching rooms of this or that college. But a lot more, a lot not noticed by either historians or even the all seeing all knowing Wikipedia, are or were sitting in museums around the world. Collected, by scientists wearing military uniforms, on military ventures, with a scientific twist.

So the science-military link is not exclusive to astronomy and astrophysics.

I wrote elsewhere about the person I met who was taking Pentagon funding to build an object that would help cure cancer. An example of a scientist subverting the military funding process. And so on.

OK, my complaint.

The authors have two long chapters (and references elsewhere) covering the early history of human endeavor in general (not limited to military) and the evolution of astronomy, mainly as it related, over a very long period of time, to navigation. One chapter covers land, the other the sea.

Staring somewhere along the way in each chapter, we get a very nice, well done, and pretty full description of the process of humans learning about the stars, about the earth and how to find one’s way, etc. But prior to that, the authors do what so many authors do and I so much dislike. I’ve written about this before. We get a version of human prehistory, and indeed, current human variation (or at least, ethnographically recent), that is bogus. For example, the authors speak of the first modern humans wandering around in the Rift Valley of Africa. There is no evidence that modern humans evolved there. Using just the archaeology, southern Africa is a more likely origin, and the physical anthropology record is simply incomplete. There are early fossils there, but that is because the rift valley is and was a big hole that made fossils. The entire rest of the continent is big, and the evolution probably happened there, not in the rift.

Similarly, ethnographic variation we see in the present and recent times is stripped out. For example, most rain forest dwelling foragers are not known to have a sky oriented cosmology, or to use the sky for much information about seasonal change in ecology, or navigation. And, there have always been a lot of rain forest dwelling foragers.

Putting that criticism aside, however, Accessory to War: The Unspoken Alliance Between Astrophysics and the Military is a very enjoyable and informative read, and makes all the important points about the sometimes uneasy, sometimes too easy, relationship between science and the military enterprise, with a careful look at politics, government, and powerful industrial interests.

Now we also need a book on the broader issue of military-technology links. And, we need a personal ray gun that zaps out of control robots:

If I can’t have my flying car, can I please have my flying battery?

Spread the love

MIT Technology review has a fascinating writeup on efforts to build electric planes. In my view, these efforts are at the same time shooting too low (the result would be the equivalent of flying short buses, at most) and possibly doable (which is good).

Have you ever noticed how much electricity weighs? Here is an experiment you can do. Get two identical alkaline batteries (small ones, like AA size), one totally discharged and the other fully charged.

Now, hold one in each hand and see if you can tell which one is heavier. Is the charged up one heavier?

No, of course not. Electricity stored as potential energy in a battery actually weighs nothing. This is an interesting idea. Airplane fuel does weigh something, but electricity itself does not. If only we could create a battery that weights almost nothing to carry all that weight-free electricity!

OK, now, while you are still holding the batteries, try something else. Do this quickly, because you don’t want anyone asking you “why are you holding these batteries” right now, because you’d have to say, “I’m trying to see how much electricity weighs,” and that is kind of a stupid question.

Hold the batteries over a hard surface that you don’t mind dropping a battery on. Maybe ten inches to a foot above the surface. Hold them upright. Now, drop them on the surface and see how they act.

The “full” battery, the one with the charge, will normally bounce better than the “empty” one.

This proves that something interesting is going on inside the battery. What? I don’t know, but I suspect it is at least tangentially related to the science behind the aforementioned MIT Technology Review write up: Top battery scientists have a plan to electrify flight and slash airline emissions. Go read it, it is very interesting.

After reading this, I had this thought: Have a relatively small battery i an aircraft that does not use the same exact technology as the long distance battery, and is good at ONLY rapid output of a lot of power, and is replaced and recycled after every flight. Ideally, the plane would actually drop the battery once it is done using it. Neighbors of airports may object.

Delete those annoying Google Chrome autosuggestions in the URL bar

Spread the love

How to erase specific autosuggested URLs from Google Chrome?

You know the problem. You are accustom to swooping into the URL entry space on your browser and typing the first three or four letters of a website you commonly visit, hitting enter, and getting where you need to be. But Google Chrome, it an undying effort to be as helpful as possible, starts suggesting subpages of that site you visited once before, and are unlikely to visit again, ever.

For example, you want to look for something on Amazon. So you type in “Amaz” and suddenly the correct URL comes up, you hit ENTER and there you are. That is how it used to be. But now, you type “Amaz” and hit enter and you are now looking at an entry for a specific light switch you searched for last week. Forever. From now on, all of your searching on Amazon will start with this one light switch.

How do you stop this madness?

Simple: Once the URL you don’t like is visible in the search bar, use the down arrow key to put the focus on that very same URL down on the list that will also appear below the search bar. Then, use Shift-DELETE to eliminate that URL forever. Or any others.

Shift-DELETE simply removes that URL from your search history. Don’t worry, it will not delete that actual web site or anything. Totally safe.

How to be a better LEGO architect in 1001 easy lessons

Spread the love

Some of the earliest LEGO sets were for buildings or some sort of structure, and to this day architecture forms a core part of the LEGO panoply. If you build an architecture project from a kit, you’ll see that they are highly engineered. In order to make a LEGO project look like something other than a concoction of random bricks made by some kids having fun (which is, of course, just fine), serious planning has to have happened.

Most of the LEGO books I’ve seen are pure idea books. If you wanted to build a project based on what you see in the books, you have to either have a huge collection of LEGO parts very well organized, or you have to be prepared to order several specific bricks that are called for in the books.

But that is the wrong way to play with LEGOs. The books demonstrate concepts, give you ideas, guide you to become a better LEGOer.

Very few LEGO books that I’ve seen are clearly this, clearly about methods and techniques, as The LEGO Architecture Idea Book: 1001 Ideas for Brickwork, Siding, Windows, Columns, Roofing, and Much, Much More by Alice Finch.

How does this work? Let me give you an example. Say you want to build a building with nice columns. There are many different kinds of columns out there in architecture land, and you can imagine that there are different ways to build each one, and which method you use depends, in turn, on the scale you are working on. Say you want to build columns that would go with a building that would work well with the assumption that the building will be used by minifigs (the small LEGO people that come with many kits). Finch gives you sixteen pages of ideas for columns, starting out with these two:

Or maybe you are in need of some curved walls:

Or stained glass:

Or towers:

You get the point.

LEGOs are bricks, and bricks are used to build buildings, and The LEGO Architecture Idea Book: 1001 Ideas for Brickwork, Siding, Windows, Columns, Roofing, and Much, Much More is a really helpful guide to developing the methods and techniques for doing that.

The wizzard behind the book, Alice Finch, is one of the top LEGO builders in the world, famous for her extensive renditions of Harry Potter’s world and other major projects (see below). This is a great book for the aspiring LEGO builder, and an excellent choice as a holiday gift for your LEGO-loving offspring.

Learn SQL and Tell Stories With Your Data

Spread the love

First, let’s get this one thing out of the way. How do you pronounce “SQL.”

Donald Chamberlin, the co-developer of SQL, pronounces it by saying the letter out louse. Ess Cue Ell. However, many computer science teachers prefer “sequel” and in at least one poll, the latte won out. One of the most common implementations of the database language is mySQL, and that piece of software is officially pronounced “My Ess Cue Ell” and not “Mysequel.”

I myself have never once uttered the word “sequel” when referring to this database system. I have also never once uttered either the term “Jiff” or “Giff” in relation to *.gif files. They are, to me, “Gee Eye Eff” files. I admit, however, to calling *.jpg files “Jay pegs” even when they are not *.jpeg.

But I digress. We are here to talk about a new book, on SQL.

The book is Practical SQL: A Beginner’s Guide to Storytelling with Data by the award winning journalist Anthony DeBarros. DeBarros is as much of a writer as he is a database geek, which gives this book a pleasant twist.

The book provides what you need to know to create databases and set up relationships. But don’t get excited, this is not a dating book.

See, a “database” isn’t really a thing, but a collection of things. Normally, at the root of a database is a set of tables, which look like squared off sections of spreadsheets, or highly organized lists, if you lay them out. But then, the different fields (columns) of the tables are related to each other. This is important. Let’s say you have a table of individuals in your club, and each individual has a set of skills they bring to the table. It is a model railroad club, so you’ve got engineers, artificial vegetation experts, landscape sculptors, background and sky painters, and so on. Also, each club member has a known set of days of the week and hours that they are available to meet or to manage some event you are having. Plus, they each have lunch food and drinks preferences for when you order out. Three of the members drive wheelchairs. And so on.

You have a table of dates and times that will be when your club will meet over the next year. You have a list of venues you will meet in. Each venue is associated with a different deli where you order out. Some of the venues are not wheelchair friendly, while some are.

Imagine putting together a big chart that shows all the events, who is going to them, what everyone will eat, what everyone will do, and special needs requirements, for the next ten years.

If that was one single giant structured table, each time a given member was included on a sublist because he or she, there would also be all the information about the person’s address, phone number, email, food preference, skill, etc. etc.

So you don’t do that. Instead, the database is taught to associate the name of each member with that member’s personal file, including all that personal information, in a way that lets you selective ignore or include that information. Then, the database lets you construct new, novel, virtual tables that combine the information in a clever way.

For instance, for an upcoming event, you can have a to-do list that includes which materials to order for a build of a new model, and whether or not the person who helps Joe with the wheelchair thing should be sent a note to remind him to definitely come, and a precise list to send to the corner deli, as well as the phone number of the deli, for lunch, and so on.

Tables, linked together with relationships, which are then mined to make these novel tables which are called queries.

You may need to import data, export data, clean up errors, you may be using a GIS system, creating automatic emails or mail merge documents, and at some point you might even want to analyze the data.

Practical SQL: A Beginner’s Guide to Storytelling with Data tells you all the stuff you need to do in order to carry out these tasks. As is the usual case with No Starch Press books, the code that is used in the book is downloadable.

The book assumes you are using PostgreSQL, which is free (and there are instructions to get it) but all SQL systems are very similar, so that really doesn’t matter too much.

Everybody who works with data should know some SQL. All desktop operating systems (Linux, MacOS, Windows) use this sort of software and it runs about the same way on all of them. Just so you know, you are using SQL now reading this blog, because SQL or something like it lies at the base of pretty much every common way of serving up web pages. Prior to you clicking on the link, these very words were in a database file, along with the name of the post, a link to the graphic used, etc. etc. A bit of PHP code accessed the data from the SQL database and rendered it into HTML, which was then fed to your browser. SQL is one of those things that lies at the root of how we communicate on line, and the basics of how it works and what you can do with it have not changed in a long time. The first relational models go back to 1970. Remember “dbase”? That was an early version, deployed in the early 1980s. By the mid 1980s, everything you can do with modern SQL, to speak of, was implemented.

To save the planet, this is what we have to do everywhere, all the time.

Spread the love

A huge amount of energy is spent going to the store. The grocery store, the hardware store, all the stores. The amount of energy spent to get an object to the store for you to buy is big, but this process is on average highly efficient. A train can hold a lot of objects, and pushing a train down the tracks is highly efficient. Also, we will hopefully eventually be running trains entirely on a combination of electricity delivered to the train indirectly, batteries, and bio-fueled generators on board. Delivering object for you to buy at the store is already efficient, but it will become more efficient with a relatively small number of (big) step.

But then everybody leaves their home and drives various distances to various stores. When I was a kid, there were two grocery stores in our neighborhood. One had no parking lot, the other had room for about five or six cars, but nobody drove to either one. We used those two wheel carts you drag along to the store (or laundromat). When you get to the grocery store, you fold the cart up and hook it to a push car, then, when you pack up your groceries, they go in that two wheeler and you drag it home. Everybody did that all the time. It was strange to drive your car to the grocery store.

I remember when my parents started to drive to get groceries. Instead of going to the store on foot (or more likely, sending one of the offspring to the store with a list), they would drive out to the edge of town to a large warehouse discount store that had sprung up, like a Cosco. Oddly, large suburban style grocery stores emerged, in my world, after these edge-of-town discount store. My parents would drive the station wagon out there, spend all day, come back and and fill the freezer and cupboards. Maybe once every six weeks. In between times, for milk and other perishables that you can’t freeze, it would be walking to the A&P. So that was all pretty efficient.

But today, tens of millions of Americans get in a car and drive a few miles to pick up some object or bunch of objects at the stores. The energy spent to do that is large. The total amount of energy we spend going to the store to get objects is probably less than the total amount of energy spent to get objects from producers (via warehouses) to stores, but not by as much as you might think.

One way to solve this is to not go to the store in a car and by an object. Order it on line. The delivery will be more efficient. Or, in some cases, go to the store on foot, bike, or public transit, get your your stuff in a big pile, and then have the store deliver it to your house. And, have all the delivery done by electric vehicles charged with energy produced without fossil carbon.

I envision a future in which we abandon mail boxes and replace them with small rooms with an indoor and outdoor access, some insulation and modest climate control, a place to put frozen stuff, refrigerator stuff, other stuff. That’s where the grocery store delivery service drops your stuff.

Or, if you are in need of new flat packed furniture, Ikea:

In a couple of years, if you buy a Malm bed at Ikea in Brooklyn and opt for delivery, Ikea will probably drop it off in an electric truck. The company is transitioning to zero-emissions delivery in New York, Los Angeles, Amsterdam, Paris, and Shanghai by 2020. By 2025, Ikea aims to do the same for every store worldwide.

“Climate change is no longer just a threat, but it’s a reality,” says Jesper Brodin, CEO of Ikea Group. “We see how that impacts our business, our customers, and our coworkers more or less everyday . . . We want to be a leader, and take action, and speed up our plans.”

The company had announced earlier this year that it would shift to zero-emissions delivery by 2025, but now plans to work more quickly in key cities.

But where do you get one of those nice delivery receiving futuristic mail boxes with the climate control?

The United States Space Force

Spread the love

Finally, we are getting a Space Force!

Now is our chance to chime in on how the Space Force should be organized and what it should do.

I have the following suggestions.

First, make no mistake, the Space Force is to fight off new alien invasions, and to find, root out, and kill any and all aliens from previous alien invasions. I know, I know, most people believe there are no aliens, or if they are out there somewhere in the Universe, they are not going to invade us. But those unbelievers tend to be Democrats, and the Space Force is a Republican idea. So, my first suggestion is to put aside any equivocation. USSF is our first line of defense against aliens. Own it.

Second, do incorporate a scientist high up in the chain of command. Time and time again, we have seen either aliens or home-grown monsters (usually as a result of nuclear radiation in the sea or someplace) get way ahead of the US Military because military commanders are bad at listening to scientists.

The senior scientist, and his attractive 20-something daughters, and the other more junior scientist or perhaps journalist on whom the daughter is sweet, should not be ignored! We should know this by now!

Third, the USSF should be in the business of separating children from their parents. None of this liberal namby pamby nice guy shit. When you get an alien child away from its parents, you do NOT reunite them. That is just asking for trouble.

Fifth, even though the USSF will diligently search for, find, and kill all existing aliens from previous invasions, it is ESSENTIAL that their technology be preserved and studies. As sure as The Doctor’s favorite expression is “Sorry” and his second favorite expression is “Run!!!” we will need that technology to fight future aliens.

Fourth, do not eschew or fail to respect the space forces that exist already in other countries. Just as American intelligence services have a “special relationship” with British intelligence, the USSF should develop and nurture a special relationship with Torchwood.

And speaking of special relationships, the USSF should have liaison with the secret service. It is not uncommon for aliens to masquerade as high level politicians, or to seduce them in other ways.

The creation of the United States Space Force is a great idea, an idea whose time is come. But I think it is very important to not pretend it is something other than it is. It is an idea to win the hearts and minds of the 21% of the United States population who believe in aliens, and were abducted by them one or more times. I worry a little about the 2% of Americans who believe they are aliens. But in any law enforcement or military operation, there are always a few who just won’t go along with the rest.

The Marines have “Semper Fidelis.” The Army has “This We’ll Defend. The US Air Force says “Aim high, Fly-Fight-Win.” And the Navy’s motto, and they just got this motto last year, is “Forged by the Sea.” (I’ll bet you thought it was “not just a job, but an adventure,” but no, you were wrong if you thought that.)

The motto of the United States Space Force? I’ll go ahead and suggest “Klaatu barada nikto,” but you should feel free to suggest your ideas below.

And finally, this shall be the United States Space Force uniform:

Kids Learn Coding with Scratch Cards

Spread the love

First, in case you don’t know, “Scratch” is a programming language and environment.

Its mascot is a cat, of course, but the name “scratch” supposedly comes from the use of scratching by disk jockeys. Scratch was first developed at MIT back in the early 2000s, and has advanced considerably since then. You now see the basic format of this language either duplicated or mimicked in many different environments.

Scratch can be an online langauge or you can run a stand alone version, but the former is easier and better. To get started, go here and follow instructions.

If you want (your kid or you) to learn scratch fast, you may want to consider getting the cards produced by No Starch Press. You can get ScratchJr Coding Cards for ages 5 and up, or the much more advanced Scratch Coding Cards for kids 8 and above.

The idea is simple. You put the stack of cards on your desk next to the computer, which is tuned to the MIT Scratch site. Then you try out the stuff in the cards. By the time you are done you (or your kid if you step aside and allow access to the computer) will be pretty good at scratch programming.

I used the 3 year and above cards with Huxley, and we are about to start on the 8 and above cards, although he is very advanced and we are likely to skip past the first several.

By the way, Scratch runs on the web so you can access it from any sort of desktop or laptop computer including Chromebooks,a nd there are iOS and Android versions. It runs on the Kindle Fire as well.

Elon Musk, Tesla, pasta, and the questionable nature of stocks and the free market.

Spread the love

Apropos the current startling developments with respect to Tesla and Musk (he tweeted he may have Tesla go private at $420 a share, above current prices), I have some thoughts I’ve been meaning to eventually get out there for comment and critique. I wonder, suspect, that what I’m thinking is related to the idea that Tesla going private is a good thing for the company and its customers, and for the cars themselves. The following scenario is what I suspect (but do not know) happened in relation to a well known company that I will anonymize here by using a different name. I’ll call it “Pastas.”

So, there was this food emporium called Pastas. The idea was to specialize in Pasta, since everybody loves Pasta, and to provide a range of options of pasta at a good price. You would go to a counter to order the pasta, but someone would bring the food to your table, along with a napkin-wrapped set of silverware. When you were done eating, they would bus your table for you. This placed Pastas clearly outside the normal range for fast food, yet in the same comfortable (and fast) ball park.

Over time, Pastas stock went up, as more and more stores were open. People buy the stock because it is going up. This investment fuels more franchises, advertising, other development. The value of the company goes up because its numbers look good, and that adds to the value of the stock itself, because people want to buy it.

Eventually, every strip mall and commercial zone in America that can have a Pastas, almost, has one.

When stores were being added, income streams were being added. Earnings went up because of this, plus, because an older franchise can have a higher profit margin than a brand new one. But once the market was saturated with stores, the income stream could not grow that way any longer. This caused the value of the stocks to stop going up as much as they were. Instead of always going up, a lot when the overall market went up, a little when the overall market went down, Pastas stock now went both up and down. And every time it went down, there was the stock market equivalent of a stern look. News report: “Pastas stocks have gone down for the first time since the company did yada yada” and that sort of thing.

Pastas needed to increase its own value somehow to keep stock holders happy, else they put Pastas stock in their “sell when you need the cash to buy into the Next Big Thing” category. But most of the previous increases were from opening new stores, and all the stores that could exist, pretty much already existed. There had to be other ways to increase value.

Note: At this stage, everybody loves Pastas. No stores are closing. There are no layoffs. The restaurant continues to do well, people buy lots of Pastas product (pasta), vendors and employees get paid, etc. Everything is just fine. The only thing that is off is the value of the stock, stabilizing or dropping slightly, not because of a change in inherent value of the company, but because the company had filled its space.

Everything is just fine but one thing: The stock market does not understand that the store has value, and needs to see earnings increase — not just stay the same but go up — or they don’t hold the stock.

So, what does Pastas do?

In order, roughly:

1) Stop bringing silverware and napkins to the table. One might think this would make very little difference, but it saves money because it saves a measurable bit of time. It is also one less thing for employees to get right, so one can spend less time training.

2) Stop clearing tables. This saves even more money for similar reasons.

3) Reduce quality of some of the ingredients if it saves money.

4) Reductions in pay to employees, or slowing down raises, or less training.

As these or similar steps are carried out, the earnings go up because costs go down. Not by a lot, but enough to stop the bleeding.

As this sort of thing happens, Pastas starts to decline in quality. No longer to people say,”Hey, this new place is great, try it out.” People keep going to eat there, sure, but only out of habit and because while quality has gone down, it is tolerable.

Over time, a measurable number of customers become annoyed when their local Pastas gives them a dose of extra bad service, and are less inclined to go there.

The number of customers stops increasing, which offsets the small gains from increased stinginess. The number of customers who walk away and come back less frequently or not at all goes up, which exacerbates the problem.

Earning drop. Stockholders, believing as they do in the perfection, wisdom, and sanctity of the Free Market, don’t understand that the real reason the value of the stock drops is because of their prissy irrational behavior. They blame it on — well, whatever excuse they can think of that does not incriminate themselves. More stocks sell. Value drops. Pastas starts to cut its losses any way they can. Eventually, Pastas, a good idea well done, disappears from the American landscape, cast aside by the invisible, and brainless hand of the Free Market. Pastas is gone, having died of its own success.

But the cause of death isn’t only success. What really killed Pastas is the fact that it was a publicly owned company.

Perhaps something like that is why Musk wants Tesla taken out of public ownership.

A neat trick to secure your home from invaders

Spread the love

First, get an Amazon Echo. You probably already have one, but if not, you’ll need it.

The Echo has this thing called “skills.” A skill is a bit of software that provides the device with some sort of ability. (see for example this post on a math-building skill.)

Once you have the Echo, install the Away Mode skill. You can get it here.

Once installed, Away Mode allows you to tell your Echo to play a long and involved audio of actors playing out various scenarios. If the volume is correctly adjusted, potential home invaders will hear this as conversations happening inside the house, and say away.

These are totally realistic scenes. For example, there is a book club meeting where everything except the book is discussed. It runs for 6 minutes. There is a guy planning a podcast about himself, an emergency PTA meeting to discuss fidget spinners, and a couple having a breakup while also watching TV. In other words, your life.
