I am about to fly to Brazil to speak at a conference. It is the first time I will be there since their recent election, which brings up interesting questions.

When I go to academic conferences around the world, I rarely encounter anyone who supports the current U.S. administration. I don’t find this surprising.

After all, academics who travel to other countries to meet with colleagues tend not to be isolationists. It is our nature to reach out to people from other cultures and find common ground.

In case you missed it, Brazil recently elected a president who is even more isolationist than ours, difficult as that is to imagine. I don’t expect to find many colleagues from Brazil who support his policies.

So I feel that I will find common cause with my Brazilian colleagues. Yet I wonder how best to approach the situation.

It seems to me that it would be rude to criticize the government of a country in which I am an invited guest. Yet as a citizen of the U.S., I believe I am free to get up in public and speak freely about my own government.

In particular, I am free to criticize the leaders of my own country when they promote hateful and isolationist ideologies. That is not merely my right — in a democracy it is my obligation.

The people listening in my host country might find themselves drawing certain parallels. And that is certainly their right. It is, perhaps, their obligation.

I like to develop successively faster methods for typing text on different portable devices, as advancing technology allows. It’s been a long term hobby of mine — and of others as well.

Yet as speech-to-text gets progressively better, and as SmartGlasses begin to replace SmartPhones in the next few years, the entire issue might become moot. Typing on a keyboard may eventually go the way of the quill pen.

I would find that to be sad, because I really like to write by typing. In fact, I am typing this on my MacBook keyboard right now, and the feeling is immensely satisfying.

Then again, even when we get to those direct-brain interfaces (scary thought), everything doesn’t need to be up to date. I’m sure nobody will object if, every once in a while, I write a letter to a future friend with a good old fashioned quill pen.

I was listening to the Beatles today and I remembered that since I was a kid I always wondered about Rose and Valerie. If you are a hardcore Beatles fan, you probably have wondered that as well.

As humans, we seem to have a fondness for naming anything that comes in twos. I remember as a child being fascinated by the goldfish in the TV show The Courtship of Eddie’s Father. Eddie named them Chet and David, and every night he would say “Goodnight Chet. Goodnight David.”

I thought that was a very cool move, and it made me feel very sophisticated as a child, because it was a very meta moment of one TV show slyly calling out to another. Some of you probably know the reference.

I have friends with two dogs, a boy dog and a girl dog. They named the boy Simba and the girl Nala. It’s great for me, because I have no problem remembering the names of their dogs.

I also have colleagues in Columbia University who do research with cuttlefish. There was one pair of cuttlefish they hoped to mate. They called them Becks and Posh.

Alas, the love story turned out to be a tragedy. Cuttlefish are very territorial, and when my colleagues finally put the two creatures together, it turned out Becks and Posh were both male. Becks promptly killed Posh.

Fortunately for Eddie, goldfish are more peaceable. Come to think of it, we have no way of knowing whether Chet and David were both boy goldfish.

Then again, it doesn’t really matter. Eddie was cool.

Today the U.S. President referred to the impeachment hearings against him as a “lynching”. It’s an odd verb to use to describe a legal procedure that was set up in the U.S. Constitution for Congress to follow.

Some Americans feel that the word is inappropriate, because people like them have had experience with actual lynchings. But it might be hard for other Americans to fully appreciate that.

So I suggest that the President mix it up a bit by rotating his verbs from day to day. That would allow more Americans to participate in his fascinating experiment in language stretching.

For example, on some days he might refer to the impeachment hearings by saying he is being raped. Women in particular might then be given an opportunity to appreciate how powerful certain unexpected words can be when coming from their President.

On other days, he might refer to it as a genocide. That will have the advantage of bringing Native Americans on board.

Personally, I would hate to see my own ethnic group left out of the process. So maybe every once in a while, our President can just refer to this annoying inconvenience as a Holocaust.

I’ve been flying a lot on airplanes these days, and it has given me an idea. When you are on a plane, particularly if there is any turbulence, your body is subjected to all sorts of interesting forces of acceleration.

In fact, as I type this, I am on a flight from California to NY, and we are going through a patch of turbulence. When I close my eyes, I can image all sorts of possibilities for how my body might be moving in flight.

It should be relatively straightforward to use your SmartPhone’s accelerometer to feed into a VR program that gives you a fascinating feeling of free flight.

The hardware set-up could be as simple as the cardboard VR viewer developed by Mark Bolas and his research team at USC. I remember getting and putting together one of their kits in 2012.

It’s an approach better known these days as “Google Cardboard”. In 2014 Google borrowed the concept and, to their credit, gave it much wider distribution.

Now you can buy foldable viewers of this type from China in bulk for about $2 a pop. Last Spring I bought 50 of those and handed them out to all the students in my computer graphics class.

It is not obvious what would be the best mapping from phone accelerometer to virtual motion, and there are many possibilities. Depending on your goal, you could convert any given acceleration to either limear movement or rotation.

So your VR flying experience might, for example, involve swooping down near to the ground, following by rapid movement over terrain, then soaring up high into the clouds to bank into turns and do rolling loops. There is a lot of room here for artistic license.

I think this would be really fun. In any case, it would be a lot more immersive than watching some stupid movie on that tiny seat-back screen.

Today I learned some very valuable life lessons. Unfortunately I think it will be quite a long time until I understand them.

But maybe that’s ok. There’s nothing like having a good long term project.

🙂

I have a habit of reading the Wikipedia each day to find out what happened on this day in history. I find it to be a rich source of cultural and historical knowledge.

Much of it is battles and conquests. For example, the only three events listed for the 11th century are:

• 1009 – Fatimid caliph Al-Hakim bi-Amr Allah demolishes the Church of the Holy Sepulchre in Jerusalem.
• 1016 – Cnut the Great completes his conquest of England in the Battle of Assandun.
• 1081 – Byzantine–Norman wars: The Normans defeat the Byzantine Empire in the Battle of Dyrrhachium.

Pretty dark stuff. Yet interspersed with all of the killing there are gems that uplift the spirit. For example, today in history Moby Dick was published, the BBC was founded, the first transistor radio was announced, and the very first human-made spacecraft landed on the planet Venus.

Sometimes I will learn about something completely new and unexpected. When that happens I might do a deep dive, spending the next hour or so happily exploring some fascinating cultural topic.

I highly recommend this practice. It will enrich your life, and quite possibly put a spring in your step.

I just watched Joker. I know that a lot of critics have had a problem with it. Yet all the people I know and trust told me the critics are wrong, so I went to see it.

And I really liked it. Yes it has a lot of violence, and quite a few disturbing things happen.

But I was ok with that, and then I found myself wondering why. After all, I have had serious problems with violence in many recent popular offerings.

I had to stop watching Game of Thrones. I quickly turned away from House of Cards. I couldn’t get through Breaking Bad. I found myself sickened by The Boys.

Yet I had no problem with Joker. And I think I know why.

For all of its insanity and violence, Joker takes place in an essentially moral universe. There is a concept of right and wrong, and the Joker himself, even in his highly disturbed state of mind, knows this.

He is, in fact, a vigilante, although a highly warped one. He has a sense of right and wrong, and he only wreaks violence upon people who are “bad” according to his internal moral compass.

Of course that does not make the violence right. In fact, by staying within a moral universe, Joker makes it clear that the Joker and the Dark Knight are two sides of the same coin.

Each believes that by taking justice into his own hands he is fighting against evil, and each understands that there are good people in the world. Of course their respective concepts of justice couldn’t be more different.

Therein lies the tension that drives their deeply dysfunctional relationship. This is what draws us to the mythic struggle between Batman and the Joker.

In contrast, Game of Thrones, House of Cards, Breaking Bad and The Boys take place in essentially amoral universes. Bad things keep happening to good people because — well — shit happens.

I’ve realized that I am just fine with violence in art. For all their horrors, I had no problem at all with Son of Saul or Amour.

In each case the violence was part of a valid struggle, a struggle that acknowledged the possibility of goodness. Those who struggle may end up failing, but the universe itself does not fail.

What I am not ok with is something that purports to be art, yet depicts a universe devoid of any inherent morality. If you watch too much of that stuff, you might be tempted to vote cruel bullies and amoral creeps into elected office.

And then where would we be?
