## The essential pattern of mathematical activities.

As I understand it, mathematics is built upon a foundation of axioms and well-agreed assumptions. And from there everything else is deduction based on logic.

So can we say, the scope of mathematics has been determined once the foundation has been established. And all people do after that is to put various logical derivations into real world practice. Though it is difficult to find all possible logical derivations. And through this, the effectiveness/correctness of the foundation is validated.

## navigation – How can I make an essential navigational treeview sidebar work on mobile?

I’m currently working on a web application that will have significant user-created content. I
would like to organize this content hierarchically, with a side-bar on the left to navigate, some buttons above it, a navbar at the top, and the main content to the right filling up the whole page. This is similar to what Atlassian’s Confluence does (except I’ll probably have a bit less text above the treeview for navigaton):

(image source)

On a desktop or laptop, or even maybe a tablet, this works great — the user can quickly get an overview of the structure of the content that they’re looking at, collapse irrelevant parts, and quickly jump to any page. Additionally, I can use the space above the treeview to show other information and provide UI that is common to each section.

But, on mobile (a phone), this UI is much worse. I could have a collapsible sidebar to the side, but I’ve used a competitor web application that does this and it results in the system being very difficult to use. Furthermore, I already have a hamburger button for a collapsible navbar, so having two may be confusing, and at the very least will be clunky in any way that I can see to do it. I could put the sidebar before the main page content, but then the user has to scroll to get at the content on the page that they want to view, which is likely to be annoying, and I want a very smooth user experience. If I put it on the bottom, below the main content, then the user is liable to miss it.

As such, I ask, how can I take the information that is presented in this design on desktops and laptops, and cleanly, smoothly, reliably, and easily (for the user) present it on mobile?

EDIT: I tried loading a Confluence instance on my phone, and it was a disaster — it basically renders as a desktop application with some of the text enlarged. It looks like they put no thought into the mobile design, or, at least, if they did then it’s not setup on the instance that I checked.

## covid 19 – Categories passenger locator form essential travel via Belgium

The Belgian Essential Travel sworn statement has a number of categories, but I’m not sure which one I should pick.

Specifically, I am an EU resident with primary residence in another EU country (not Belgium). I’m considering transiting in Belgium on my return from an essential trip outside the EU.

My entire trip (assuming I choose Belgium as my entry point back to the EU) looks as follows:

EU country of residence =flight=> non-EU country where my physical presence is required (this is the main reason for my entire trip) =flight=> Brussels (entry-point back to the EU) =car=> EU country of residence

The Belgian Passenger Locator Form has a number of essential travel categories which may seem relevant, but it mostly depends on whether I choose the category for my entire trip (as described above) or the trip back home (i.e. starting at the the non-EU country where my physical presence is required).

If it is the former, I could choose the option ‘a trip in the context of a legal obligation, insofar as it is necessary and cannot be done online’ and bring along supporting documents showing that my physical presence is required at my destination. Of course that won’t support the need for my trip back home.

If choosing the latter, I would simply argue that I am travelling home and that such a trip is essential per se. Two options in the form seem to support that reason:

• a transit trip;
• for an individual whose primary residence is abroad: departure from Belgium after a trip which commenced before 27 January 2021.

The last reason is phrased a bit ambiguously, I’m not sure if this applies only to those who are already in Belgium (so that this reason only supports travel departing Belgium) or if it also applies to arrivals who plan to leave immediately (the trip, regardless of how it is defined starts after January 27th).

The transit reason seems the most straightforward if my assumption that travelling home is always essential.

TL;DR:
Do the essential travel categories on the Belgian passenger locator form refer to the trip as a whole or to the (narrowest) part of the trip that involves travel through Belgium?
