São Paulo City by Ciro Santilli 37 Updated 2025-07-16
Although Ciro Santilli lived in São Paulo City nominally during his studies, it would be more precise to say that he lived in University of São Paulo-land, because Ciro was cheap, didn't have a car, and did nothing but study, stay at home, go back to Santos to see his parents and the beach.
But the little he saw of the city made a deep impression on him.
The unreasonable size.
The unbearable contrasts.
Caetano's Sampa is the ultimate description of the city!
Five votes:
  • Deputado federal: total elected 513[ref]
  • Deputado estadual
  • Senador: total elected: 81[ref], [ref]
  • Governador: total elected: 1 per state
  • Presidente: 13 Lula. Total elected: 1
All but president are per state. Official list seems to be e.g. for Sao Paulo: divulgacandcontas.tse.jus.br/divulga/#/estados/2022/2040602022/SP/candidatos
Japanese Brazilians by Ciro Santilli 37 Updated 2025-07-16
Japanese Brazilians are either model children, or they're good for nothings. There is no intermediate.
Francisca Nneka Okeke is a Nigerian physicist and professor known for her work in the field of physics, particularly in areas related to space and atmospheric sciences. She has made significant contributions to the understanding of the ionosphere and its impact on radio wave propagation. Additionally, Okeke is an advocate for promoting science education and has been involved in various initiatives to encourage young women and girls to pursue careers in science and technology.
21st-century New Zealand physicists have made significant contributions across a variety of fields within physics, including experimental physics, theoretical physics, astrophysics, and materials science. Some notable physicists and their contributions include: 1. **Sir Paul Callaghan** - An influential physicist known for his work in the fields of magnetic resonance imaging (MRI) and materials science. He was also a prominent science communicator, advocating for the importance of science in society.
Jan Beenakker is a prominent Dutch physicist known for his work in condensed matter physics, particularly in the areas of quantum transport, mesoscopic physics, and superconductivity. He has made significant contributions to the understanding of properties and behaviors of materials at the nanoscale. His research often explores phenomena such as quantum coherence, quantum interference, and the interplay between electronic and spin degrees of freedom in various systems.
Apatite is a group of phosphate minerals that are widely found in nature. The general formula for apatite is often represented as Ca5(PO4)3(F,Cl,OH), indicating that it primarily consists of calcium phosphate, with varying amounts of fluorine, chlorine, or hydroxyl ions. It comes in several forms and colors and is an important component of biological systems, particularly in the formation of bones and teeth in vertebrates.

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.
    Figure 5. . You can also edit articles on the Web editor without installing anything locally.

  4. Infinitely deep tables of contents:
