  • This is a funny comic, but I dislike how it perpetuates a common misunderstanding of stoicism that it’s about suppressing or ignoring your feelings, when it’s actually about engaging with your feelings as deeply, mindfully, and intentionally as possible. It’s about trying to understand why you feel the way you do, and also trying to understand how your feelings can lead you to acting in a manner which contradicts your values. A stoic master wouldn’t ignore their anger, especially if their anger is the result of witnessing their own teachings being misrepresented and used to further injustice. They would just be careful not to let their anger lead them to acting rashly and doing something which will ultimately undermine the virtues they want to cultivate in themselves and in the world.


  • The idea that the velocity of a person walking forward on a train is simply the velocity of the train plus the velocity of the person walking with respect to the train is called “Galilean relativity”.

    Einstein realized that Galilean relativity has a big problem if you take for granted the idea that the speed of light is the same for all observers, regardless of reference frame, and people had a lot of reasons at the time to suspect this to be true.

    In particular, he imagined something like watching a train passing by him, but on board the train is a special clock which works by shooting a pulse of light at a mirror directly overhead which reflects back down and hits a sensor. Every time the light pulse hits the sensor, the clock ticks up by one and another light pulse is sent out. People usually call this the “light clock thought experiment” if you want to learn more about it.

    Anyway, Einstein realized if he was watching the light clock as the train passed by him while he’s standing on the station, the path the light beam traces out will take the form of a zigzag. Meanwhile, for a person standing on the train, it will just be going straight up and down. If you know anything about triangles, you will realize that the zigzag path is longer than the straight up and down path. So if everyone observes the speed of light to be the same exact thing, it must be the case that it will take the light a longer amount of time to traverse the zigzag path. And so the person standing on the platform will see that clock ticking slower than the person on the train will. This phenomenon is called “time dilation”.

    From this point, you can apply some simple trigonometry to figure out just how much slower things would be appearing to move on the train. And it turns out that the velocity the person watching the train observes the person walking on the train to have is not the velocity of the train plus the velocity of the person walking on the train. But rather, it’s something like that velocity, but divided by 1 + (train velocity)•(walking velocity)/c^2, where c is the speed of light (and this is called “Lorentzian relativity” if you want to read more about it).

    It’s important to notice that since trains and walking come nowhere close to the speed of light, the value you’re adding to one is very small in these kinds of situations, and so what you’re left with is almost exactly the same thing you would get with Galilean relativity, which is why it still is useful and works. But when you want to consider the physics of objects that are moving much much faster, all of this is extremely important to take into account.

    And lastly if you wanna read more about this stuff in general, this is all part of “the theory of special relativity” and there’s probably helpful YouTube videos covering every single thing that I’ve put in quotation marks.


  • is there any particular reason you’re saying that besides cynicism? I am having trouble finding specifics, but there’s a lot of reporting that the MTA is expecting to raise $15 billion from congestion tolling to fund public transportation repairs and improvements and pretty much all of the proposals for this in the past required all of the revenues to be earmarked for use by the MTA



  • First of all, I did not say that proton is opposing capitalism. I said that to oppose capitalism does not mean you have to be opposed to free enterprise. As in, you can be opposed to an economy comprised primarily of capitalist institutions without being opposed to the concept of free enterprise. Proton is simply an example of such a business, which can be used as evidence for the fact that it is entirely possible to start businesses in a free market economy which are actually interested in solving problems as opposed to using the existence of problems as a vehicle to enrich a class of shareholders.

    Second of all, “it’s filling a niche created by other companies’ poor privacy policies” is essentially nothing more than a restatement of the second sentence I wrote, which I will repeat here: “I pointed out that as long as it’s a for-profit corporation, it would have not have any financial or legal incentive to continue pursuing its mission if it ever achieved a certain level of market share.”. You’re right that them adopting a nonprofit structure doesn’t change that, but it does change their ability to sell out their customers at the discretion of a class of shareholders, unlike any business which is owned by private individuals.


  • I remember one time I criticized proton for positioning itself as community oriented while still being a for-profit corporation. I pointed out that as long as it’s a for-profit corporation, it would have not have any financial or legal incentive to continue pursuing its mission if it ever achieved a certain level of market share. But then several months later, they actually announced that they were going to put their money where their mouth is, and transition to a nonprofit structure.

    I think that proton is perhaps the greatest example at the moment that to oppose capitalism does not mean you have to be opposed to free enterprise, and people should always think about this sort of thing when they listen to any kind of business leader try to convince them that it’s actually really important that they be allowed to cash out whenever they want.

    I can’t imagine that their set up is perfect, but I definitely am going to have to give this offer serious consideration.












  • College is often sold to the working class as some kind of vocational training that will prepare them for highly sought after knowledge based careers. But really think about it: before the mid 20th century, who was the typical college student? Was it a person who had to worry about the consequences of unemployment even if they couldn’t find work?

    The next question to ask yourself is: why did these people go to college anyway if it wasn’t for career reasons? And is it something valuable that we are losing as administrators make college more about jobs?


  • A lot of nonprofit organizations will try to justify underpaying workers on the basis of social interest. However, it certainly is not some kind of requirement and many do offer compensation which is competitive with what the private sector offers. And furthermore, if more firms in the market were structured in a cooperative or nonprofit manner such that this became the expectation instead of the exception, these firms would not easily be able to get away with underpaying workers because they’re not actually doing something special anymore.

    By the way, none of this is to say that this would magically solve all of our problems or anything like that. It’s only that there will be a lot fewer problems to worry about when most businesses are legally obligated to prioritize the interests of consumers and workers above arbitrary shareholders


  • Never forget that when a business owner tells you that they put consumers first, nothing is stopping them from converting their business into either a cooperative or a nonprofit organization dedicated to the public benefit. Even if it’s the case that at some given moment, the business really is putting consumers first, there is no benefit to the consumer for the business to continue operating as a privately owned for-profit institution. The only benefit a for-profit institution provides that a cooperative or nonprofit cannot, is the power for leadership to prioritize their own interests above all other stakeholders whenever it suits them.


  • The most amazing part is not even that long ago, everyone agreed this is how it worked, even the business owners. I remember recently watching the 1923 silent film “Safety Last!” starring Harold Lloyd. I was very struck by a particular scene in the film where the owner of the store Harold Lloyd works at says:

    “I’d give $1000 for a new idea that would attract an enormous crowd to our store. Something is wrong with our exploitation! We simply are not getting the publicity that our position in the commercial world calls for.”

    This character is not presented as some kind of villain or saying something wrong. He’s just talking about how everyone understands business to work, by exploitation, which has always simply meant taking advantage of some kind of opportunity, even when people like Marx talked about it.
