The ATRAP (Antihydrogen Trapping Experiment) is a scientific experiment designed to study antihydrogen, the antimatter counterpart of hydrogen. Conducted at CERN (the European Organization for Nuclear Research), ATRAP focuses on producing and capturing antihydrogen atoms, which consist of an antiproton (the antimatter equivalent of a proton) and a positron (the antimatter equivalent of an electron).
Organic semiconductors are materials that possess semiconductor properties and are primarily composed of carbon-based compounds. These materials can conduct electricity due to the presence of pi-conjugated systems, where electrons can move freely along the molecular chains.
Strained silicon refers to a modified form of silicon that has undergone mechanical deformation to enhance its electrical properties, particularly in semiconductor applications. This technique is used primarily in the manufacturing of transistors and integrated circuits. ### Key Points about Strained Silicon: 1. **Mechanical Strain**: Straining silicon involves stretching or compressing the material to create a lattice deformation.
Candelilla wax is a natural plant-based wax derived from the leaves of the candelilla plant (Euphorbia antisyphilitica), which is native to northern Mexico and the southwestern United States. This wax is obtained by harvesting the leaves of the plant and then processing them to remove the wax, typically through a boiling or extraction process. Candelilla wax is known for its hard, brittle texture and has a pale yellow to brown color.
Ceresin is a type of wax that is derived from the process of refining and purifying certain natural waxes, particularly from ozokerite, a naturally occurring hydrocarbon wax. It appears as a white or pale yellow solid with a higher melting point compared to many other waxes, typically around 80 to 90 degrees Celsius (176 to 194 degrees Fahrenheit).
Jojoba ester is a derivative of jojoba oil, which is extracted from the seeds of the jojoba plant (Simmondsia chinensis). Jojoba oil itself is a liquid wax ester rather than a true oil, and it closely resembles the human sebum, making it a popular ingredient in cosmetics and skincare products. Jojoba esters are created through esterification, where the fatty acids in jojoba oil are combined with fatty alcohols.
Ozokerite, also known as ozocerite or ozokerite wax, is a naturally occurring mineral wax that is primarily composed of hydrocarbons. It is typically found in association with other types of mineral deposits, particularly in sedimentary rocks. Ozokerite is characterized by its dark color, which can range from brown to black, and its waxy texture.
Rice bran wax is a natural wax derived from the outer layer of the rice kernel, specifically obtained from rice bran, which is a byproduct of rice milling. This wax is composed of long-chain fatty acids, fatty alcohols, and esters, and it is often recognized for its emollient and thickening properties.
Turtle Wax is a brand known for producing car care products, particularly those focused on vehicle cleaning, polishing, and protection. The company was founded in 1944 and has since become one of the most recognized names in the automotive detailing industry. Turtle Wax offers a wide range of products, including waxes, polishes, washes, tire cleaners, and interior cleaning solutions. Their products are designed to help maintain and enhance the appearance of vehicles, providing shine and protecting surfaces from environmental damage.
Uranium minerals are naturally occurring minerals that contain uranium in significant amounts. Uranium is a radioactive element, and its minerals are typically found in various geological environments, often associated with other elements such as sulfur, oxygen, and various metals. Some of the most common uranium-bearing minerals include: 1. **Uraninite (Pitchblende)** - This is the most important ore of uranium, consisting mainly of uranium dioxide (UO₂) and often contains other elements like thorium and lead.
The International Uranium Film Festival is an annual film festival focused on showcasing documentaries, feature films, and short films that address the themes of uranium mining, nuclear energy, and the broader issues surrounding nuclear technology, including its environmental and humanitarian impacts. Founded in 2010 in Brazil, the festival aims to raise awareness about the consequences of nuclear activities, particularly in regions affected by uranium mining and nuclear fallout.
The uranium mining debate revolves around the extraction of uranium ore for use in nuclear power generation and its associated environmental, health, economic, and ethical implications. Here are some of the key points and issues at the center of this debate: ### 1. **Environmental Impact** - **Pollution and Habitat Disruption:** Critics argue that mining activities can lead to soil and water contamination, disrupt local ecosystems, and cause deforestation or habitat loss.
"Chronopolis" is a short story written by the science fiction author Michael Moorcock. It was first published in 1971 and is known for its exploration of time travel and the concept of a city that exists outside the normal flow of time. In the story, Chronopolis is a sprawling city where time is manipulated and controlled, reflecting Moorcock's themes of chaos and order. The narrative often touches upon the philosophical implications of time, existence, and the nature of reality.
"Momo" is a novel written by German author Michael Ende, first published in 1973. The story centers around a young girl named Momo, who possesses a unique ability to listen and help others. She lives in an abandoned amphitheater on the outskirts of a city and forms strong bonds with various characters in her community. The plot unfolds as Momo encounters "the Grey Gentlemen," mysterious figures who steal time from people, leading them to live rushed, unfulfilled lives.
"Gantz: E" is a manga series that is part of the "Gantz" franchise, created by Hiroya Oku, who is known for the original "Gantz" series. This particular installment is set in the same universe as the original work but features new characters and storylines. The "Gantz" series is renowned for its sci-fi elements, graphic violence, and philosophical themes.
"The Humanoids" can refer to various cultural works and concepts, depending on the context. Here are a couple of notable examples: 1. **Science Fiction Comic**: "The Humanoids" is a famous graphic novel series created by French artist Moebius (Jean Giraud) and writer Alexandro Jodorowsky in the early 1970s.
Cosmic Research typically refers to the scientific study of the universe, encompassing a wide range of topics such as cosmology, astronomy, astrophysics, and astrochemistry. It aims to understand the origins, evolution, and structure of the universe, as well as the fundamental physical laws that govern celestial phenomena.
The key content previously on this page was moved to the following sections:
Since images are large, they bring the following challenges:
To solve those problems, the following alternatives appear to be stable enough and should be used decreasing preference:
- This way, the entire website is relies on a single third party: GitHub, so we have a simple single point of failure.We are at the mercy of GitHub's 1GB size policy: help.github.com/en/articles/what-is-my-disk-quota, but it will take a while to hit that.GitLab however has a 10Gb maximum size: about.gitlab.com/2015/04/08/gitlab-dot-com-storage-limit-raised-to-10gb-per-repo/ so we could move there is we ever blow up 1Gb on GitHub.
- Wikimedia Commons for videos if the following conditions are met:
- in scope: "educational material in a broad sense", but not e.g. "Private image collections, e.g. private party photos, photos of yourself and your friends, your collection of holiday snaps and so on.". I don't think they will be too picky even with low quality photos.
- allowed format, e.g. images or videos, but not ZIPs
- allowed license: CC BY SA, but no fair use
Since Wikimedia Commons has a higher level of curation and is an educational not-for-profit, it is the method most likely to remain available for the longest time.For this reason, we highly recommend uploading any acceptable files there as well as an additional backup.The downside is that its tooling is not as good, e.g. there are a bunch of messy unofficial tools for batch operations, and upload takes more effort.Another downside of Wikimedia Commons is that while we can choose the basename of files, it also adds some extra SHA crap to the beginning of URLs, making them harder to predict.Another serious downside is that they randomly rename images without redirects... e.g. they renamed upload.wikimedia.org/wikipedia/en/0/03/STJ_SVG_file.svg to upload.wikimedia.org/wikipedia/commons/8/81/Superconducting_tunnel_junction.svgAnother "downside" is that they are extremely strict about copyright compliance. This is good because you can be pretty sure that they are correct in general, but it also means that they are very conservative, and delete things where fair use would be OK. And if those fair uses have no Wikipedia page, they won't show up anywhere. - All content will be tracked under the
cirosantillicollection: archive.org/details/cirosantilliarchive.org has a very convenient upload and lax requirements. The generated URLs are predictable (single SHA prefix for the entire collection).Never trust a website that is not on GitHub Pages, for-profit companies will take down everything immediately as soon as it stops making them money.Every external link to non-GitHub pages must be archived. And GitHub links must be forked.We should also backup images that Wikimedia Commons does not accept here in addition to the github.com/cirosantilli/media repository.
The following alternatives seem impossible because Ciro could not find if they expose direct links to the images:
The following do have direct links:
- www.flickr.com e.g. live.staticflickr.com/7437/27402357162_7d91b73cd5_z.jpg documented at help.flickr.com/en_us/get-the-url-of-a-flickr-photo-S1Hnnmjym Also does automatic image size conversion. But only provides ugly autogenerated URLs.
- Instagram does not support upload from computer? Lol?
A functional shift, also known as a shift in grammatical function or part of speech shift, refers to the process in linguistics where a word changes its function (or part of speech) without any additional morphological change. This means that a word originally belonging to one grammatical category (like noun, verb, adjective, etc.) is used as a word from a different category.
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.Figure 1. Screenshot of the "Derivative" topic page.
