Minimal interactive UI simulation of a simple MJCF scene with one falling cube:Test soure code: github.com/google-deepmind/mujoco/blob/5d46c39529819d1b31249e249ca399f306a108ac/sample/basic.cc. The only thing you can do is rotate the scene with the computer mouse it seems. Mentioned at: mujoco.readthedocs.io/en/2.2.2/programming.html#sabasic

model/ directory: github.com/google-deepmind/mujoco/tree/5d46c39529819d1b31249e249ca399f306a108ac/model E.g. the imaginary humanoid robot DeepMind used in many demos can be seen with:bin/basic ../model/humanoid/humanoid.xmlA more advanced UI with a few controls:Test soure code: github.com/google-deepmind/mujoco/tree/5d46c39529819d1b31249e249ca399f306a108ac/simulate.

bin/simulate ../doc/_static/hello.xmlA very cool thing about that UI is that you can manually control joints. There are no joints in the hello.xml, but e.g. with the humanoid model:under "Control" you move each joint of the robot separately which is quite cool.

The term "visible life" refers to multicellular from before people knew there was life in the proterozoic.
Flux linkage is a key concept in electromagnetism and electrical engineering, particularly in the study of inductors and transformers. It refers to the total magnetic flux (\(\Phi\)) that links with a coil or a loop of wire. This concept is critical for understanding how inductors work and how electromagnetic induction occurs.
A shock tube is a device used primarily in experimental fluid dynamics and shock wave research to study the behavior of gases under shock wave conditions. It consists of a long, narrow tube divided into two segments by a diaphragm. One segment (the driver section) is filled with a high-pressure gas, while the other segment (the driven section) is filled with a low-pressure gas.
"Ngan" can refer to a few different things depending on the context: 1. **Currency**: In some contexts, especially in Southeast Asia, "ngan" is a unit of currency. For example, in Thailand, "ngan" is a traditional unit of measurement for silver and gold but is not commonly used in currency today. 2. **Names**: "Ngan" can also be a name, particularly in Vietnamese culture.
The term "Tbl" can refer to different things depending on the context. Here are a few possibilities: 1. **Tabular Data**: In programming and data science, "Tbl" is sometimes used as shorthand for "table," referring to structured data organized in rows and columns. 2. **TBL (The Business Logic Layer)**: It can stand for a specific component in software architecture that handles business logic within an application. 3. **TBL (Tech Bureau, Ltd.
Dewetting is a phenomenon that occurs when a liquid film retracts or breaks away from a solid surface, leading to the formation of droplets. This can happen when the adhesive forces between the liquid and the solid are weaker than the cohesive forces within the liquid. In other words, if the liquid prefers to stay in a droplet form rather than spread out over the surface, dewetting may occur.
Pinned article: 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!
Intro to OurBigBook
. Source. We have two killer features:
- 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-calculusArticles 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.

- to OurBigBook.com to get awesome multi-user features like topics and likes
- as HTML files to a static website, which you can host yourself for free on many external providers like GitHub Pages, and remain in full control
