Possible to publish pages: www.notion.so/help/public-pages-and-web-publishing
But non-paid plan currently disables "Search engine indexing" of that sharing, so it's useless. There's an "Allow duplicate as template" button though which is nice.
URLs are horrendous however, e.g.: lofty-flower-be4.notion.site/aa-2274c59a06124d5b974b781a67340670 Only the
aa in that came from us. They don't even have the guts for a fixed subdomain.They don't show multiple input pages on the same render, e.g.: lofty-flower-be4.notion.site/aa-2274c59a06124d5b974b781a67340670 does not contain the child lofty-flower-be4.notion.site/bb-45df7212a2e14e04b3f9604035c7acf4 as already implemented on OurBigBook Web Dynamic Article Tree.
Cross page links to work fine. But you don't link to explicit IDs, only internal hidden IDs. This can be even slightly confusing to users as multiple identical options can show up when you start creating a link. They do try to disambiguate with the parent page however.
So this is a reasonable single-person publishing platform for your notes.
Someone made and sold a helper for it:

Are LEDs monochromatic? Created 2024-06-26 Updated 2025-07-16
Lasers emit a narrow spectrum Created 2024-06-26 Updated 2025-07-16
It emits a very narrow range of frequencies (small linewidth), which for many purposes can be considered a single frequency.
It does however have a small range of frequencies. The smaller the range, the better the laser quality.

- they have a separate DB entry for everything in the page, e.g. even list items. A little bit like OurBigBook dynamic tree but way more blocks
- they use PostgreSQL of course

Lasers vs other light sources Created 2024-06-26 Updated 2025-07-16
The key advantages of lasers over other light sources are:
- lasers emit a narrow spectrum
- it can be efficient collimated, while still emitting a lot of output power: Section "Why can't you collimate incoherent light as well as a laser?"
- can be phase and polarization coherent, though it is not always the case? TODO.
One cool thing about lasers is that they rely on one specific atomic energy level transition to produce light. This is why they are able to to be so monchromatic. Compare this to:As such, lasers manage to largely overcome "temperature distribution-like" effects that create wider wave spectrum
- incandescent bulbs: wide black-body radiation spectrum
- LED: has a wider spectrum fundamentally related to an energy distribution, related: Why aren't LEDs monochromatic
- TODO think a bit about fluorescent lamps. These also rely on atomic energy transitions, but many of them are present at once, which makes the spectrum very noisy. But would individual lines be very narrow?

Education of André-Marie Ampère Created 2024-06-26 Updated 2025-07-16

Jean-Jacques Ampère, a successful merchant, was an admirer of the philosophy of Jean-Jacques Rousseau, whose theories of education (as outlined in his treatise Émile) were the basis of Ampère's education. Rousseau believed that young boys should avoid formal schooling and pursue instead a "direct education from nature." Ampère's father actualized this ideal by allowing his son to educate himself within the walls of his well-stocked library.
