I am going to be 26 soon, but I am still very terrible at navigating to places. I often get lost, even in smaller cities (or even a train station!), and have to constantly look up on Google Maps (with GPS), ask people, miss connections, taken wrong connections, running around in circles trying to find my destination.

Has anyone here been like me and considerably improved their spatial awareness and navigational skill? How?

There are so many mathematical ideas that can be interpreted in multiple ways/ can be used to explain many things with the same theory. For instance, addition in Galois Field of order 2 is same as binary XOR, or that irreducible polynomials exhibit prime number like properties, etc.

I'm sure that there is a general process of consolidation and generalization to come up with better i.e. a more inclusive theory. I am curious if there are books of this kind in mathematics that try to explain to the reader the same concept from different angles?

I am mostly interested in Algebra, but I'll appreciate pretty much any suggestion.

>>> From his quote "You don't understand anything until you learn it more than one way", I am guessing that Minsky might have experienced a similar thing.

I notice that a lot of German domain names have dashes in the URL (something that I've been trained to not love at first sight (pun intended)).

A quick lookup gave me these:

Berlin School of Economics and Law [https://www.hwr-berlin.de/en/] Hamburg University [https://www.uni-hamburg.de/en.html] University of Heidelberg [https://www.uni-heidelberg.de/en] Some Startup List [https://startup-map.berlin/home]

And even some of the top Alexa websites:

https://www.t-online.de/ https://www.wer-weiss-was.de/

Based on my basic knowledge of the German language, there is no such unusual usage of dashes in the language itself, but there are far too many URLs that use dashes. Any reason/ thoughts?

Since I was a kid (im ~23), I have always been fascinated by printers- of all sorts. I developed a liking towards certain HP model, which was an inkjet printer and very portable... until I had to get a new cartridge. So I figured out a way to refill the ink cartridges and pray that it'd work.

I'm curious why no one worked on creating really portable printer (Epson Workforce WF-100 for example) with different ink options, so the printer is really just one time investment and the ink could be just as cheap as it can get. Currently, it seems like an oligarchy where the goal is to sell printers and then keep making money by selling single use cartridges.

On the other hand, the space like 3d printers, or mechanical keyboard is already getting so much 'indie' development. I'd personally love to buy a printer (like my mechanical keyboard) that I can use every once in a while and something that is easily/cheaply refillable.

I have always been fascinated by the idea of (tech) startups. I always felt that startups are not just some other apples, but are a different fruit altogether. And one of the primary attractions in them is the culture- a bit informal, and yet hyper-productive; personal, and yet respectful; transparent and quite flat and approachable.

I get the point that if the startup goes on to expand like crazy and new people keep coming in (and leaving), there would emerge things like hierarchy, pointy-haired bosses, management and HR and what not.

What I don't get it is that why would startups with <10-15 employees and over years in operation would want to behave like a BIG company. I have encountered startups where there would be management, useless meeting, artificial hierarchy, etc. when there seems to be no such need. To satisfy my curiosity, I'd ask the 'individuals' of the startup individually, and none would seem to like it or knows why 'they' are doing it, and yet they do it. Why does it happen then? Do startups feel good by mimicking big corporation cultures?
