This is an official ODERSA website. Here’s how you know

The official domain

The address of this site ends in odersa.org. Every service the association runs sits on a subdomain of odersa.org and nowhere else. If the address in your browser’s address bar does not end in odersa.org, this site is not ours.

Free, and no account

Everything is open straight away. No sign-up, no account, no password, no subscription, no advertising. Nothing is held back for those who pay, because there is nothing to pay for.

No data collected

This site does not follow you: no tracker, no tracking cookie, no measurement tool built into these pages, and nothing measured on your device. Our host counts requests in aggregate, as any server that answers does: a total, never a profile. You do not have to take our word for it: open your browser’s developer tools, go to the Network tab, and reload the page. You will see the full list of what the site asks for. Everything comes from odersa.org, nothing goes anywhere else.

Free to reuse

The content is published under the CC BY 4.0 licence. You may copy it, translate it, print it and pass it on, for your classes as much as for the people around you, on one condition only: credit ODERSA.

Knowledge programme

The long version is the interesting one

learning for the pleasure of knowing

This programme holds what the association publishes about science, history, and general knowledge: what is known, how it came to be known, and why the full version is almost always more interesting than the shortcut in circulation. It exists for curiosity itself, with no exam waiting at the end, and it speaks as much to an adult who never finished studying as to a pupil who is bored.

The good question is not what we know, it is how we came to know it.

An isolated result is learned and forgotten. The story of how it was found, with its dead ends and the moment somebody thought to measure differently, stays without effort and travels elsewhere: it is a way of reasoning, not one more piece of information.

It is also the best protection against second-hand knowledge. Anyone who knows how a result was established recognizes at once the claim that never followed that road, without needing to be a specialist in the subject.

The approach

How we know what we know

An observation that does not fit

Almost every discovery starts with a detail that will not settle: a measurement that comes out wrong, an object where it should not be, an explanation that works everywhere except here.

An explanation that can be proved wrong

A hypothesis is only worth something if you can imagine the result that would contradict it. An idea compatible with absolutely everything explains nothing: it is the most useful line between a science and a belief.

A check made by other people

A result holds when people with no stake in it find the same thing, or correct it. Knowledge is not the word of a learned person: it is what survived everyone else’s scrutiny.

Why this field matters

Curiosity is the one engine that does not stop at the school gate

Many adults come out of school feeling they were sorted once and for all: arts or sciences, gifted or not. It is untrue, and it is expensive. Picking a subject back up at thirty or at sixty goes perfectly well, on one condition: that the way in is interesting in itself and there is nothing to pass at the end.

General knowledge is not an ornament either. It is what lets you attach a new piece of information to something you already know, and therefore understand it instead of memorizing it. With nothing to attach it to, information stays an isolated sentence, and an isolated sentence survives neither forgetting nor the first simplified version that comes along.

So this programme keeps to a modest principle: tell what is established, say when something is not, and give each story back the trial and error usually cut out of it. What stays gripping about a discovery is almost always what the summary removed.

Who it is for

Those who learn alone, and those who teach

Learning for yourself

Adults who came back to knowledge out of curiosity, pupils who want to go further than the syllabus, people a long way from formal study: no entry condition, no level required, nothing to pass on the way out.

  • Free and account-free, including for long reading
  • Subjects that stand on their own, in any order
  • Sources you can consult, to carry on by yourself

Helping others learn

Teachers, activity leaders, librarians, families: this programme supplies material to tell and to search through, rather than sheets to recite.

  • Reusable in a lesson, a workshop, or at home
  • CC BY 4.0 license: adapting to the level of the group is allowed
  • Printable, for working away from a screen

The shape

What this programme publishes, and how

The field changes from one programme to the next; the shape does not. These construction rules are not promises: they can be checked today, on the 12 actions the association already has online.

The invariants

  • Free, no account, no ads, for every audience.
  • No data collected: no cookie, no tracker, no request to a third-party server.
  • Content under a CC BY 4.0 license: reuse, adapt, translate, republish, with one attribution line.
  • Open data as JSON, so anyone can recount every figure stated.
  • What is established and what is debated are not presented the same way, and the difference is written out plainly.

The last line is the most demanding one on this subject: it means giving up definitive phrasing whenever the state of knowledge does not allow it.

Keep going

The shape described above can be checked on the 12 actions the association already has online, which the map names with their format, their languages and their real reach.
