Kauri gum is a natural resin obtained from the kauri tree (Agathis australis), which is native to New Zealand. The gum is formed when the tree's bark is damaged or when it is under stress, causing resin to seep out and eventually harden over time. Kauri gum can be found in various forms, ranging from small droplets to larger chunks.
Amber is a fossilized tree resin that has been appreciated for its beauty and durability for millions of years. It often features a warm, yellow to orange-brown coloration, although it can come in other hues as well, including green, blue, and even white. Amber is notable for sometimes containing inclusions of prehistoric organisms, such as insects, spiders, and plant material, which were trapped in the resin before it hardened.

He is associated with academic institutions and research organizations where he focuses on understanding the mechanisms of bacterial infections and developing strategies for combating infectious diseases.
As of my last update, Thomas Greytak is not a widely recognized public figure, historical person, or concept, so I'm unable to provide specific information without additional context.
Tom Baehr-Jones is not a widely recognized public figure, and there is not a significant amount of verifiable information available about him in the public domain. It's possible that he may be known within a specific community or field that has not garnered broader attention.
Thomas James Bernatowicz is not a widely recognized figure in public knowledge up to my last training cut-off in October 2023. It's possible that he could be a private individual, an emerging personality, or a figure within a specialized field not covered extensively in mainstream sources.
Amorphous metals, also known as metallic glasses, are a class of materials that lack a long-range periodic atomic arrangement, which is characteristic of crystalline metals. Instead, their atomic structure is disordered, resembling that of liquids. This lack of crystallinity gives amorphous metals unique physical properties, such as high strength, good corrosion resistance, and excellent magnetic properties.

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.
