Introduction

L’énergie solaire est en passe de devenir l’une des sources d’énergie renouvelable les plus prometteuses au monde. Face à la demande mondiale croissante de solutions énergétiques durables, l’énergie solaire se distingue comme une ressource énergétique propre, renouvelable et inépuisable. La technologie des panneaux solaires, qui convertissent la lumière du soleil en électricité, progresse à un rythme remarquable, offrant une alternative aux combustibles fossiles conventionnels. Alors que les préoccupations concernant le changement climatique se multiplient, exploiter l’énergie solaire est devenue non seulement une question d’innovation, mais aussi une nécessité pour un avenir durable.

La Science Derrière L’énergie Solaire

Au cœur de la technologie de l’énergie solaire se trouve le système photovoltaïque (PV), qui capte la lumière du soleil et la convertit en électricité. Les panneaux solaires sont constitués de cellules solaires contenant des semi-conducteurs, généralement du silicium, qui absorbent les photons de la lumière du soleil. Lorsque la lumière du soleil frappe ces cellules, elle excite les électrons du matériau semi-conducteur, générant un flux d’électricité. Ce processus est connu sous le nom d’effet photovoltaïque. L’efficacité des panneaux solaires dans la conversion de la lumière du soleil en énergie s’améliore régulièrement, faisant de l’énergie solaire une option plus viable pour les besoins énergétiques résidentiels et commerciaux.

De L’énergie Solaire

L’une des raisons les plus convaincantes de l’adoption croissante de l’énergie solaire est son impact environnemental. L’énergie solaire est propre et ne produit aucune émission de gaz à effet de serre, ce qui en fait un acteur clé dans la réduction de l’empreinte carbone mondiale. En passant à l’énergie solaire, les sociétés peuvent réduire leur dépendance aux combustibles fossiles comme le charbon, le pétrole et le gaz naturel, qui contribuent à la pollution de l’air et au réchauffement climatique. L’énergie solaire contribue également à préserver les ressources en eau car elle ne nécessite pas les grandes quantités d’eau nécessaires au refroidissement des centrales électriques conventionnelles.

De plus, l’énergie solaire peut contribuer de manière significative à l’indépendance énergétique. En installant des panneaux solaires, les ménages et les entreprises peuvent produire leur propre électricité, réduisant ainsi leur dépendance au réseau et s’isolant de la hausse des coûts de l’énergie. Dans les zones reculées ou hors réseau, l’énergie solaire offre une solution énergétique fiable et durable, fournissant de l’électricité là où elle pourrait autrement être indisponible.

L’avenir De L’énergie Solaire : Tendances Et Innovations

Alors que le monde évolue vers un avenir énergétique plus durable, la technologie de l’énergie solaire est sur le point de connaître des avancées significatives. Les chercheurs améliorent continuellement l’efficacité des cellules solaires, en travaillant sur des matériaux tels que la perovskite, qui promet d’être moins chère et plus efficace que les cellules solaires traditionnelles à base de silicium. De plus, l’intégration de l’énergie solaire avec des systèmes de stockage d’énergie comme les batteries est une avancée majeure. L’énergie solaire peut être captée pendant la journée et stockée pour être utilisée la nuit ou par temps nuageux, surmontant l’une des principales limites de l’énergie solaire : sa nature intermittente.

Les innovations dans la conception des panneaux solaires rendent également l’énergie solaire plus accessible. Les panneaux solaires deviennent de plus en plus esthétiques, avec des options telles que les tuiles solaires et les fenêtres solaires qui s’intègrent parfaitement à l’architecture moderne. L’efficacité accrue de ces panneaux signifie qu’ils peuvent être installés dans un plus large éventail d’environnements, des toits urbains aux fermes rurales, élargissant ainsi leur potentiel d’adoption généralisée.

Conclusion

L’énergie solaire est sans aucun doute l’avenir de l’énergie. Sa capacité à fournir une électricité propre, renouvelable et rentable en fait un outil essentiel dans la lutte contre le changement climatique. À mesure que la technologie continue de progresser et que le monde adopte des pratiques plus durables, l’énergie solaire joue un rôle de plus en plus essentiel dans la construction d’un avenir plus vert et plus propre. Exploiter l’énergie solaire n’est pas seulement une prouesse scientifique : c’est la voie vers un système énergétique mondial plus durable et plus résilient.


Exploiter Le Soleil : L’avenir De L’énergie Solaire

Interesting article. I can't decide if it's SPAM or a test and if it is AI generated. I especially like the Indonesian "Baca selengkapnya klik di sini" in the middle of French text.

Anyways, welcome to OurBigBook.


Is it SPAM?

This is somewhat what I was looking for: https://github.com/KaTeX/KaTeX/blob/main/contrib/mhchem/README.md

I'd prefer something that doesn't go through math, but it's not bad. We could also add a helper to hide the math part of it.

If there's ever enough interests from chemists I could try to enable it.

Greetings from 2025!

Fascinating SPAM, I wonder if you are a scammer doing it manually, or an actual service company that hires spammers for them. I'm flattered yet again.

In the context of an A* search, a heuristic function is said to be admissible if it does not overestimate the cost to reach the goal. Such functions can also be viewed as being "optimistic".

When using an admissible heuristic, A* is \b[guaranteed to return a cost-optimal solution], i.e. the best path. Let's prove it by contradiction:

Assume that the algorithm returned a path, the cost of which is greater than that of the optimal path $P$. Let's call $C$ the cost of the path that was followed, and $C^*$ the cost of $P$, noting that $C^* < C$. First, we can safely assume that at least one node in $P$ was not expanded during the algorithm's execution (if all nodes of $P$ were expanded, then $P$ would have been chosen instead since that would lead to a lower path cost$^{[1]}$). Without loss of generallity, let's take the first occurance of such unexpanded node and name it "n". Let's call the \b[actual] cost from n to the destination $h^*(n)$ and define \b[$g^*(n)$] as the cost of the \b[optimal] path starting from the origin all the way to n. Remember that A* is a best-first search on the value of $f$, so $f(x) \geq C$ for all unexpanded nodes. Here's what we've got:

$
\small
f(n) \geq C > C^*, \text{ otherwise n would have been expanded} \newline
f(n) = g(n) + h(n), \text{ by definition} \newline
f(n) = g^*(n) + h(n), \text{ n is on an optimal path } \newline
f(n) \leq g^*(n) + h^*(n), \text{ since heuristic is optimistic } (\leq \text{actual cost) } \newline
$

Now note that $g^*(n) + h^*(n)$ is equal to "the cost to reach n following the optimal path" + "the cost to reach the goal starting from n, following the optimal path". That's just equal to the total cost of the optimal path! So, both $f(n) > C^*$ and $f(n) \leq C^*$ hold simultaneously which obviously constitutes a contradiction. $\square$

\[1\]: Remember than $h(n)$ (our heuristic) is just a hint to prioritize certain expansions over others. When everything is expanded however, $g(n)$ is the sole metric that will be considered, which will always lead to the optimal path being selected, that being $P$.


Admissible Heuristic

Welcome to OurBigBook, and thanks for this article!

That sounds like a great way to rule over people o_O

\Video[https://www.youtube.com/watch?v=aGCdLKXNF3w]

BTW, maybe this was intentional but just in case, you created a new article in the same topic rather than a comment: https://ourbigbook.com/pioyi/cirocoin and shows up on the cirocoin topic: https://ourbigbook.com/go/topic/cirocoin I only noticed it because of the upvote notification I received.

If this was created on Web, which is presumably the case:

* it shows up as the first article under your homepage tree (I need to change this I think, and make it be addded lsat by default
* it will be nuked on the next ourbigbook --web CLI to web upload (since it is not present locally). I want to solve this and make web to local work perfectly as well, but it requires implementing a basic history system to detect which file changed where like Git does. In the plans.


It's like the song says: "Everybody wants to rule the world"

To make transparent images look like most users will expect them to.

Thanks for breaking the site yet again, users :-)

Or maybe it was intentional and I spoiled it for you?

Oh well, can't make everybody happy.

A common misconsception suggests that glass is a liquid of high viscosity. \b[This not the case]. Glass is its own distinct state of matter that doesn't coincide with any other classical one. Every liquid (except Helium) can be turned into glass, if a sufficiently rapid cooling takes place. This process is called \b[vitrification]. When a liquid is cooled (water for example) it normally goes through the process of crystallization. We say that the water is frozen as ice forms which has a very specific structure that is characterized by its stability (crystalline solid). If the cooling happens quickly enough, the water molecules don't have the opportunity to occupy the lowest energy sites and this is how the amorphous solids forms.

\b[Annealing] illustrates this phenomenon. When glass is cooled down in order to solidify, this process must be done during a specific time interval in order for the molecules to have enough time to position themselves in a more stable manner. If during the glass making process, the produced glass has been solidified too rapidly, then the stress present in the solid makes it too fragile to the point where it can rupture/shatter even during handling. By reheating the glass and slowly droping the temperature again, we ensure that the glass object has gained a much more stable structure.

As crystalline solids have a melting point, amorphous ones have a \b[glass transition temperature] which surprisingly depends on thermal history (how rapidly was the former liquid made into glass?). Around this temperature point, the viscosity of the glass increases rapidly and can be classified as a solid (under classical terms). It should be noted that the viscosity as well as other properties of the substance made into glass, present a continuous change as the temperature changes. This is not the case with "ordinary" freezing as liquid water turns spontaneously into a solid in a discontinuous manner (during the freezing process the temperature stays constant. Immediately below $0^oC$ all the water has turned into ice).

The glass state is metastable and its transition to a crystalline solid is thermodynamically favoured although kinetically inert.


Glass as a Non-classical State of Matter

I would like to learn more about state transitions. Wikipedia means full understanding of glass is an open question: https://en.wikipedia.org/wiki/List_of_unsolved_problems_in_physics which is exciting. I wonder how much can be known besides numerical simulation number crunching.


Yes, this is a really cool topic

One should not forget that our bodies can produce hydrogen sulfide with the help of speicifc bacteria found in our \b[mouth] and \b[intestines]. 

These take advantage of the sulfur found in \b[proteins] that we consume (four aminoacids, the buldings blocks of proteins, contain sulfur).  


Production of hydrogen sulfide

Currently repeating `hydrogen-sulfide` is not ideal because the ID/URL has that word duplicated:

``
/pioyi/hydrogen-sulfide/production-of-hydrogen-sulfide
``

I understand that currently perhaps this is the only choice because you want the title to show as "Prodcution of Hydrogen sulfide".

But in short/mid term I want to make scope ancestors show up on the title such sa:

``
Hydrogen sulfide / Prodcution
``

which with the current source will lead to duplication on the title as well:

``
Hydrogen sulfide / Hydogen solfide prodcution
``

So I'd either do:

``
= Hydrogen sulfide
{scope}

== Prodcution
``

or:

``
= Hydrogen sulfide

== Hydrogen sulfide prodcution
``

but not both scope and repeating as current:

``
= Hydrogen sulfide
{scope}

== Hydrogen sulfid prodcution
``


You might want to keep this just "Production" due to scope

Starch Gelatinization (Boiling of food)

Like this:

```
== Starch Gelatinization
{title2=Boiling of food}
```

It shows up as `Starch Gelatinization (Boiling of food)` on the page (but not on indexes/ToC, that could be considered but needs thought), but keeps the ID shorter to just `/pioyi/starch/starch-gelatinization` rather than `/pioyi/starch/starch-gelatinization-boiling-of-food` which is what you might want.


Btw, you might want to use <code>title2</code> in such cases

It refers to an old text that was contained in the bigb file. I remember that I interacted with this part of the file (or with a different one. I don't really remember) while I was writing the new one.

Kind of unxplainable, but my first guess was that I hadn't closed the latex segment somewhere. It turned out that everything has been closed as needed.

Am I missing something? I hope not!

This is because this title made me aware of a discreet bug because you can't have an HTML link `a` inside another `a`, which ends up happen if you put a link inside a title. The backslash prevents the link creation and fixes this.

We've also now forbade putting links like this in the title, and fixed various other related issues at around: https://github.com/ourbigbook/ourbigbook/commit/7b89f879409a415cc5bd0e35b4ee87837ea38473

Welcome to my home page!
The exquisite beauty of a well-mannered adult has been identified and examined by races all ovber the world and I am glad to say that Hubert Pumpernickle will die in a week. 


Sounds legit

Oveview

Last time I annoy you. I saw there was a typo on the title. There are two ways to handle that:

* inferior: mark article with bad ID as not visible on metadata, copy it over to good title
* superior: using synonym renaming: https://docs.ourbigbook.com/ourbigbook-web-page-renaming which gives you redirects from old to new

We really want to add a simple on click web UI way to make synonym renaming without typing.


Last tip: hiding and renaming articles

One of the key features of ourbigbook is that everything in the tree is unscoped by default. E.g. the "Overview" article actually goes under https://ourbigbook.com/pioyi/oveview and not https://ourbigbook.com/pioyi/hydrogen-sulfide/overview as you likely wanted.

The reason for that is that this is the best way to make topics work: https://docs.ourbigbook.com/#ourbigbook-web-topics and topics is basically the only feature that justifies the project.

There are two solutions to model your knowledge:

1) (recommended in this case: make a longer more specific title "Overview of Hydrogen Sulfide" or "Hydrogen sulfied overview"

2) Use scopes. Locally the tree would look like this: https://docs.ourbigbook.com/#h-scope-argument

```
= Hydrogen sulfide
{scope}

== Overview

== Production
{scope}

=== Laboratory

=== Industrial
```

which would produce a tree structure as:

```
/hydrogen-sulfide
/hydrogen-sulfide/overview
/hydrogen-sulfide/production
/hydrogen-sulfide/production/laboratory
/hydrogen-sulfide/production/industrial

```

I should also note that I'm not sure if scopes are working perfectly via web UI, though if they are not I want them to.

One big reason I don't recommend scopes in this case is that there is currently no way to unscope things. What if later on you want to add a child of "Hydrogen sulfide" but you don't want for its url to be `/hydrogen-sulfide/something`? It's not currently possible. Though I would like to support it one day.

I would also just remove the Overview section and just dump its contents on "Hydrogen sulfide" itself, since the content of an article is basically always its own overview.

I would recommed using scopes only very sparsely when you go into extremelly specific tutorials about something, which are very unlikely to have topic hits by others, e.g. https://ourbigbook.com/cirosantilli/cia-2010-covert-communication-websites though even then I end up regretting it.

Anyways we'll see, maybe at some point people will prever to use just scopes and we'll go there more.


One more tip: scopes

Claus process

You are under no obligation to use any of the following, we never ever interfere with legal user content, this is just to highlight some cool features we have:

1) if you start the article with `{wiki}` you get a wiki link to https://ourbigbook.com/pioyi/claus-process as in https://ourbigbook.com/cirosantilli/hydrogen On web UI just put:

```
{wiki}

The body of the article
```

separated by double newline. Docs: https://docs.ourbigbook.com/#h-wiki-argumen

I want to make it possible to add this kind of header metadata via UI checkboxes as well at one point: https://docs.ourbigbook.com/todo/web-header-metadata-to-widgets

2) You can also create topic links such as:

\OurBigBookExample[[
I like <#Carl Friedrich Claus>{p} he's cool.
]]

This way you don't have to actually have to create articles you have nothing to say about to save some typing, and hopefully someone will have written about the topic for you.

That is a bit of an unfortunate case where `{p}` (pluralize) is needed because without it we miss the `s` at the end:

\OurBigBookExample[[
I like <#Carl Friedrich Claus> he's cool.
]]

it misses the trailing 's' because we want <#apples> to go to singular "apple" more often than not.

3) You can interlink:

```
The Claus process served as a better replacement of the Frasch process
```

to your other articles with:

```
The <Claus process> served as a better replacement of the <#Frasch process>
```

4) For the chemical formulas, we have two resaonable ways:

LaTeX math:

\OurBigBookExample[[
$$H_2S + SO_2 \to 3S + 2H_20$$
]]

or using the `sub` and `sup` arguments:

\OurBigBookExample[[
H\sub[2]S + SO\sub[2] -> 3S + 2H\sub[2]0
]]

It would be cool one day to have a more specialized macro for chemistry like Wikipedia does: https://en.wikipedia.org/wiki/Template:Chem2


Some random tips

Whenever I try to write an article, (on your markdown, not in the CLI version), many times the text gets all deleted. This happens when I type special characters such as "dollar sign" (in fact, as I was about to rewrite it, my whole browser froze and the website was experiencing high lag for some reason). 

So for some reason I can't write all that. I can't write dot dot either. Also headers don't work!  "equals + space" seems to be one of the deadly combos that delete all content.

Some specific key combinations cause the whole text to get deleted. Please fix this issue, so we can start writing articles. Also a save button (like a draft) should be present, because you never know if anything is going to crush suddenly.

I am waiting for the updated version or for an explanation.
