Miniature model-makers are artisans or hobbyists who create scaled-down replicas of objects, scenes, or structures. This craft can include a wide range of subjects, such as buildings, vehicles, figures, and landscapes. Miniature model-making can be pursued for various purposes, including art, display, education, and entertainment. There are several aspects to miniature model-making: 1. **Materials**: Model-makers often use various materials, including wood, plastic, metal, and resin.
Music notation file formats are specialized digital file types used to represent musical notation and scores. These formats enable composers, musicians, and music educators to create, share, and store their musical compositions in a way that can be read and understood by music notation software. Various file formats serve different purposes and offer different features. Here are some common music notation file formats: 1. **MusicXML (.musicxml, .xml)**: - A standardized format for representing Western music notation.
In music, "articulations" refers to the way in which specific notes or phrases are expressed in terms of their attack, duration, and decay. Articulation affects the character and attack of each note, influencing how they are played or sung. Common types of articulations include: 1. **Staccato**: Notes are played short and detached, creating a crisp sound. 2. **Legato**: Notes are played smoothly and connected, with no noticeable breaks between them.
Ornamentation refers to the decorative elements added to a work of art, music, or architecture to enhance its aesthetic appeal or expressivity. The specifics can vary widely depending on the context: 1. **Visual Arts**: In painting, sculpture, and decorative arts, ornamentation may involve the use of patterns, textures, and colors to embellish a piece. It can include motifs, detailed patterns, or intricate designs that add richness and complexity.
Ciro Santilli is a UK resident. He will register as a "solo trader" (slightly funny legal term) and treat donations that he uses for projects as grants, which pay regular income tax:The rates are given at: www.gov.uk/income-tax-rates and are as of writing:
  • 0 - £12,570 0%
  • £12,571 - £50,270: 20%
  • £50,271 - to £125,140: 40%
  • £125,140: 45%
National insurance is also likely going to be paid: www.gov.uk/self-employed-national-insurance-rates:
  • 6% on profits between £12,570 and £50,270
  • 2% on profits over £50,270
Fortunately however VAT does not need to be paid.
The amount that will be declared is the same as he grant amount that was requested, e.g. if 100k USD is requested for 1 year, then 100k USD will be pro-rata declared on that year.
Any remaining donations that don't yet meet specific grant goals will be initially treated as cash gifts which pay no tax. If in the future they are used as grant money after further goal amounts are reached, then they will taxed as grants.
Note however that if the donor is UK-based and dies within 7 years of the gift being given, inheritance tax has to be paid on them as per: www.gov.uk/inheritance-tax/gifts, at a maximum of 32% and going to to 0% at 7 years, so let me know from the afterlife.

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!
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.

    You can publish local OurBigBook lightweight markup files to either https://OurBigBook.com or as a static website
