Makenzie Lystrup is an American aerospace engineer and notable figure in the field of space exploration. She is known for her work with NASA and has been involved in various projects related to robotic systems and space technology. Lystrup’s contributions include work on missions related to planetary exploration and the development of advanced space systems. Her expertise and leadership in the aerospace sector have made her a prominent advocate for STEM education and encouraging young people, especially women, to pursue careers in engineering and technology.
The name is a bit obscure if you don't think in very generalized terms right out of the gate. It refers to a linear polynomial of multiple variables, which by definition must have the super simple form of:and then we just put the unknown and each derivative into that simple polynomial:except that now the are not just constants, but they can also depend on the argument (but not on or its derivatives).
Explicit solutions exist for the very specific cases of:
- constant coefficients, any degree. These were known for a long time, and are were studied when Ciro was at university in the University of São Paulo.
- degree 1 and any coefficient
A solution to Laplace's equation.
TODO: in high level terms, why is QED more general than just solving the Dirac equation, and therefore explaining quantum electrodynamics experiments?
Also, is it just a bunch of differential equation (like the Dirac equation itself), or does it have some other more complicated mathematical formulation, as seems to be the case? Why do we need something more complicated than
The main high level insight seems to be that The Dirac equation does not work for more than one electron.

Ciro Santilli 40 Updated 2025-07-16Roderick Chisholm (1916–2009) was an influential American philosopher, best known for his work in epistemology, metaphysics, and philosophy of mind. He is particularly recognized for his contributions to the study of knowledge, belief, and perception, as well as for his staunch defense of a version of realism and the concept of "agent causation." Chisholm also explored concepts such as personal identity, free will, and moral responsibility.
Just like the adenine nucleotide translocator moves ATP/ADP in and out, this one moves loose phosphate in.
Both of those together recycle the cellular respiration carriers from/to the mitochondria.

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.
