PoGOLite is a balloon-borne experiment designed to study celestial gamma-ray sources, particularly pulsars and other high-energy astrophysical phenomena. The name "PoGOLite" stands for "Polarized Gamma-ray Observer: Lite," which reflects the experiment's focus on measuring the polarization of gamma rays. The main objectives of PoGOLite are to improve understanding of the nature of gamma-ray emissions from various astrophysical sources, as well as to explore the mechanisms behind these emissions.
The Wolff algorithm is a Monte Carlo method used to simulate systems in statistical mechanics, particularly for studying phase transitions in lattice models such as the Ising model. It is an alternative to the Metropolis algorithm and is particularly useful for handling systems with long-range correlations, as it can efficiently update clusters of spins instead of individual spins.
When Ciro was a teenager, he was extremely cheap e.g. for clothes, food and video games even tough his family didn't have bad financial conditions.
This was mostly to save the world by not wasting resources that other people in need could use, and to save money so he could have more money to do more of whatever he wanted without the obligation to work.
But Ciro admits that shocking people with the incredible level of low quality goods was also fun.
Ciro changed after he came to Europe, especially in regards to food, perhaps corrupted by the fact that now the best chocolates, cheeses and breads in the world were not much more expensive than the cheapest brand you could buy. He still hates clothes that are just to look good like costumes though.
Living close to a small favela, São Remo, the favela next to USP, helped Ciro get frighteningly cheap goods on the shop frequented by the favela neighbours.
One legendary story is that of when his flatmate dropped some past on the kitchen floor, and the bowl broke, but Ciro prevented the flatmate from throwing it away and ate some of it nevertheless. What spooked them out the most was Ciro's statement that the pasta now had a crunchy glass shard texture to it.
Crazy overlaps with Ciro Santilli's OurBigBook Project, Wikipedia states:
Administrators of Project Xanadu have declared it superior to the World Wide Web, with the mission statement: "Today's popular software simulates paper. The World Wide Web (another imitation of paper) trivialises our original hypertext model with one-way ever-breaking links and no management of version or contents.
During his teenage years, Ciro created an innovative new dance style combining elements of the various corporal practices that he studied a bit of across the years:
- Kung Fu/Taichi
- Brazilian Axé and Capoeira
- Breakdance
- Yoga
- Modern dance
Ciro later called this style Cirodance.
Ciro's legendary dance style was famous during his university years, when Ciro would go to parties and dance like made while mostly unsuccessfully trying to woo girls.
Ciro has always been critical of dancing conditions in University parties, where people would always be cramped up doing boring non-creative moves. Rather, Ciro would go to to the edges of the dance floor to have enough space for his amazing moves. There is a perhaps a parallel between such tendencies and Ciro's highly innovative personality. Also perhaps being cramped would have helped wooing said girls.
Ciro later quit dancing, to a large extent because it is too hard to find suitable dancing locations outside: Europe is too cold much of the year, also ground conditions have to be perfect, and no patience to book a dance room somewhere. Kid's playgrounds are ideal, but Ciro is afraid of dancing there because kids parent's would freak out.
Therefore, all evidence of Cirodance seems to have disappeared into the depths of the Internet. There used to be a notorious video on YouTube from around June 2010 entitled "A Piriguete da Poli !!" ("Poli's bitch" in Portuguese) with comment "Sem comentarios... foi a atraçao da cervejada" (No comments... was the main attraction of the beer party) dancing the Piriguete by MC Papo Brazilian Funk carioca song. But the video was removed at some point, they were likely afraid of getting sued, the URL was www.youtube.com/watch?v=T969azGjIeE as shown at www.facebook.com/cirosantilli/posts/133333123357495, but this was before Ciro noticed that every good thing on the web goes down and became an obsessive web archiver. But in any case, the title gives an idea of the amazing style of Ciro's furor poeticus Axé performance on that day. If the video owner ever reads this message, please please restore the video, or send Ciro a copy. TODO: which channel was it on? Knowing that Ciro would be able to try and contact them.
One legendary episode linked to Cirodance was when Ciro was living in Paris and jobless around 2014 (but not destitute as he leached from his girlfriend). Cirodance was his main physical activity at the time, and Place de la République, where the skateboarders hung out due to the perfect wide concrete floor and relatively close to Bastille where Ciro lived, was the perfect place for it. One cold dark winter evening, Ciro was practicing Cirodance with his headphones and crappy clothes (dirty public square floor, remember), when someone took him for a homeless person and offered him a bowl of soup! It must be said that Place de la République had many events of giving food to the poor. Ciro was a bit stunned, declined, and continued dancing. And so that was the day when a prestigious Polytechnicien was mistaken for a homeless person. And Ciro liked that.
As of 2021, Googling "cirodance" leads to www.youtube.com/watch?v=tyvv4ddL2so "Ciro Dance" in which comedian "Ciro Priello" (no Wikipedia page at the time) participates in a comedy show with a "silly dance" (TODO this likely has a name) described in the comments as:
Ciro had a small accident in 2021. It wasn't ultra serious, a few cuts, but could have been worse. Here's a post mortem.
Ciro was going to cycle 120 km between two locations he had never cycled before. Ciro had cycled this distance before many many times, so he thought he could do it.
What went wrong:
- on both ends were cities, larger than those Ciro is used to
- on the start, was a port city. You do not want to cycle in port areas, ever! Lots of trucks, narrow side-walks, bad road, danger danger!
- on both sides, endless suburbia. This means you have to check your map every 3 seconds to know which little stress to turn, which is very hard without a way to attach your map to your bike. Ciro had his on his pocket. You lose a lot of time like that!
- there wasn't a lot of sunlight at the time of the year. Not critical, but still, less than ideal.
- during the ride, part of the "well documented and safe cycle route" was closed off for repairs. It was unclear what the best alternative would be. Ciro went down a path, but it turned to be horrendous countryside, he had to pull his bike over fences
- by then, Ciro was tired and a bit late. He had only eaten sweets all day long. They give you calories, but there's always something missing in them.
- Ciro arrived at the very very large target city, and it was getting dark, and it was rush hour, lots of cars. This was already back on the official bike path, but even those paths are tortuous in suburbia
- also, Ciro was meant to meet his wife later, and he was in a rush, worried that she would be worried about him
- at one point, Ciro took the wrong turn for a few hundred meters
- he realized, and turned back
- when coming back, now extra impatient because o the wrong turn, the place he had come from was actually one way street for a very short while until the right turn, so Ciro went against the correct direction...
- a car came. It was relatively slow, because the road was slight uphill for the car, and a turn. The slight downhill also meant Ciro was going a bit faster than he realized
- Ciro tried to go into the sidewalk anyways to make sure he was clear off the car (he was already). When he tried, the wheel stuck, and he flew forward, hitting a wall slightly
You have to know when you are tired and hungry and impatient. This is where huge danger lies.
If any of you ever read this, do send me an email to Ciro Santilli saying hi and we can agree on a clear separation of usernames.
Although if you are just starting out, maybe you should just go from scratch with a unique Internet alias.

Sally Brailsford is a recognized figure in the field of operations research, management science, and decision support systems. She has made significant contributions to the development of methodologies and tools that aid in decision-making processes. Her work often intersects with healthcare, logistics, and service operations, and she has been involved in various academic and practical applications of these disciplines.
As of my last update in October 2021, there is no widely recognized figure or entity specifically known as "Yasmín Ríos-Solís". It is possible that she is a private individual, a public figure, or an emerging personality who gained recognition after that date.
Operator theorists are mathematicians who specialize in the study of operators on function spaces, mainly within the framework of functional analysis. This field investigates various types of linear operators, which are mappings that take one function (or vector) to another while preserving the structure of a vector space. Key areas of focus within operator theory include: 1. **Linear Operators**: Understanding how linear mappings act on function spaces, particularly Hilbert and Banach spaces.
The Gelfand–Naimark theorem is a fundamental result in functional analysis and the theory of C*-algebras. It establishes a deep connection between C*-algebras and normed spaces, specifically in the context of representation theory.
A differential operator is a mathematical operator used to denote the process of differentiation. In the context of a function, it takes a function as its input and produces the derivative of that function as output. Differential operators are commonly used in calculus, physics, engineering, and many other fields to analyze and describe rates of change and various physical phenomena.
In operator theory, dilation refers to a specific concept particularly relevant in the study of linear operators on Hilbert spaces. The idea of dilation relates to the representation of certain types of operators (often bounded operators) in terms of larger, often simpler, operators. Dilation can be viewed from different perspectives, including matrix dilation, functional analytic dilation, and quantum mechanical contexts. ### 1. **Unitary Dilation**: A common type of dilation in operator theory is unitary dilation.

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.
