Micro pitting by Wikipedia Bot 0
Micro pitting is a surface degradation phenomenon that occurs in rolling element bearings, gears, and other mechanical components subject to high contact stresses and alternating loads. It is characterized by the formation of small, localized wear spots or pits on the surface of the material, usually at a microscopic level. These pits can significantly affect the performance and lifespan of mechanical components by leading to increased friction, noise, and ultimately premature failure.
Microwave enhanced electrochemistry refers to a method in electrochemical processes where microwave radiation is used to enhance the efficiency and effectiveness of electrochemical reactions. This approach leverages the unique properties of microwaves, such as rapid heating and the ability to selectively energize specific molecules or ions in a solution.
Ciro Santilli's sport practice by Ciro Santilli 37 Updated +Created
Playing soccer just feels amazing, because you are constantly running around, but with a more specific goal in mind: to get that ball into that goal!
Playing soccer was specially amazing in the flat wet sand beach of Santos. weekend, the sea, feet touching the sand, the sun going down, and your school mates next to you. Nirvana.
It is also true that under those conditions, the skin of your feet will get ripped off due to running on the slightly wet and flat sand no matter how thick it has become. But it is worth it.
Teams would often be slit between "the team with shirts vs the team without shirts", who would just take off their shirts. The two best players would take turns picking players into their teams, the first one to pick would be decided by odds and evens (par ou ímpar).
A pair of Havaianas, or Havaianas rip-offs, stuck into the sand, or even just some school bags, would do as a goal posts. More organized people, especially adults, would have their own water pipe goal with a proper net and all. But doing so would spoil the fun of endless discussions if a non flat ball had gone in or not into an imaginary rectangle.
That's how soccer was meant to be played.
Ciro became however disillusioned with soccer after his injury. It is a shame.
And so after that, Ciro decided to dedicate himself to sports where you can't hurt your knee.
Ciro hates water, so swimming is out of the question. What could be more boring than going back and forth on a fixed location a million times to gain some milliseconds?
And so Ciro has been left with the gym as the only main option for a while.
Running would have been a consideration, but Ciro Santilli's legs sometimes itch when he runs.
This is until he ended up living in a place with decent roads for cycling in the late 2010's, which led to Ciro Santilli's cycling.

The Norman Hackerman Young Author Award is a recognition given to young authors in the field of science and engineering. Named after Dr. Norman Hackerman, a prominent chemist and former president of the University of Texas at Austin, the award aims to encourage and promote writing among students interested in these subjects. It typically acknowledges outstanding scientific writing or research done by young individuals, often at the high school or early college level.
The palladium-hydrogen electrode (PHE) is an electrochemical half-cell that serves as a standard reference electrode. It consists of a palladium electrode that is in contact with hydrogen gas at a controlled pressure and temperature. The key feature of this electrode is that palladium has the unique ability to absorb hydrogen, allowing it to maintain a stable hydrogen equilibrium. ### Key Components: 1. **Palladium Electrode**: A palladium metal surface that can absorb hydrogen gas.
Panel edge staining refers to the process of applying a stain or finish to the edges of wood panels or boards, typically in woodworking or cabinetry. This technique is often used to enhance the visual appeal of the edges, provide a uniform color, or match the edges to the surface of the panel. In woodworking, the edge of a panel can be left untreated or may show different characteristics compared to the surface due to the manufacturing process.
Partial current by Wikipedia Bot 0
Partial current typically refers to the flow of electric charge in a specific segment or component of an electrical system rather than the total current flowing through the entire system. This concept is useful in various contexts, such as: 1. **Circuit Analysis**: In circuit analysis, partial currents can be considered when analyzing circuits with multiple branches. For example, in a parallel circuit, each branch may carry a different current depending on its resistance, and these individual currents can be referred to as partial currents.

Pinned article: ourbigbook/introduction-to-the-ourbigbook-project

Welcome to the OurBigBook Project! Our goal is to create the perfect publishing platform for STEM subjects, and get university-level students to write the best free STEM tutorials ever.
Everyone is welcome to create an account and play with the site: ourbigbook.com/go/register. We belive that students themselves can write amazing tutorials, but teachers are welcome too. You can write about anything you want, it doesn't have to be STEM or even educational. Silly test content is very welcome and you won't be penalized in any way. Just keep it legal!
We have two killer features:
  1. topics: topics group articles by different users with the same title, e.g. here is the topic for the "Fundamental Theorem of Calculus" ourbigbook.com/go/topic/fundamental-theorem-of-calculus
    Articles of different users are sorted by upvote within each article page. This feature is a bit like:
    • a Wikipedia where each user can have their own version of each article
    • a Q&A website like Stack Overflow, where multiple people can give their views on a given topic, and the best ones are sorted by upvote. Except you don't need to wait for someone to ask first, and any topic goes, no matter how narrow or broad
    This feature makes it possible for readers to find better explanations of any topic created by other writers. And it allows writers to create an explanation in a place that readers might actually find it.

  2. local editing: you can store all your personal knowledge base content locally in a plaintext markup format that can be edited locally and published either:
    This way you can be sure that even if OurBigBook.com were to go down one day (which we have no plans to do as it is quite cheap to host!), your content will still be perfectly readable as a static site.
