As of my last knowledge update in October 2021, "Daniel McKinsey" does not refer to a notable or widely recognized figure, event, or concept. It's possible that it could be a person's name, but without more context, it's difficult to provide relevant information. If this name has gained prominence or significance after October 2021, I wouldn't have that information.
The third one from Cambridge after:

"Dark galaxy" is a term that may refer to a few different concepts in astronomy and cosmology, but it often pertains to regions of space that do not emit light in the visible spectrum, making them difficult to detect and study.

The bane of multicellularity.
A dark globular cluster is a type of astrophysical object that is essentially a globular cluster of stars but does not appear to contain significant amounts of luminous matter, particularly stars that can be readily observed. Instead, these dark globular clusters may contain a significant amount of dark matter or may be composed of stars that are dim or obscured from view, often due to dust or gas.

A cool thought about cancer expressed at Power, Sex, Suicide by Nick Lane (2006) is that cancer it is the direct product of natural selection gone wrong!
Cancer cells are obviously selected against anti-cancer mechanism, which when they manage to evade, they reproduce uncontrollably, gaining more and more momentum.

Dark radiation refers to hypothetical particles or forms of energy that may be present in the universe but do not interact with electromagnetic forces, making them invisible and undetectable by conventional means. The term is often used in cosmology and theoretical physics to describe additional forms of energy density that could play a role in the evolution of the universe beyond what is accounted for by ordinary matter (baryonic matter), dark matter, and dark energy.
The term "dark star" can refer to a few different concepts in astrophysics, but it is primarily associated with theoretical stellar objects that are powered by dark matter interactions rather than by nuclear fusion, as normal stars are. ### Key Ideas: 1. **Definition**: A dark star is a hypothetical astronomical object that exists in the early universe, formed when dark matter, which does not interact electromagnetically (i.e.

Darkon, also referred to as "unparticles," is a theoretical concept in particle physics proposed by Howard Georgi in 2007. It suggests the existence of a new type of substance that does not behave like conventional particles. Instead of having a well-defined mass and charge, unparticles are thought to appear as a continuously distributed entity with scaling dimensions that resemble those of a field. The key feature of unparticles is their scale-invariance.

Ciro Santilli was touched by this, and then watched several other documentaries by Curtis.
Notably the part of the governments have lost all power to companies, and can't do anything meaningful anymore to actually represent the people, because globalization reduces the power of governments.
Ciro Santilli would like to fully understand the statements and motivations of each the problems!
Easy to understand the motivation:
- Navier-Stokes existence and smoothness is basically the only problem that is really easy to understand the statement and motivation :-)
- p versus NP problem
Hard to understand the motivation!
- Riemann hypothesis: a bunch of results on prime numbers, and therefore possible applications to cryptographyOf course, everything of interest has already been proved conditionally on it, and the likely "true" result will in itself not have any immediate applications.As is often the case, the only usefulness would be possible new ideas from the proof technique, and people being more willing to prove stuff based on it without the risk of the hypothesis being false.
- Yang-Mills existence and mass gap: this one has to do with finding/proving the existence of a more decent formalization of quantum field theory that does not resort to tricks like perturbation theory and effective field theory with a random cutoff valueThis is important because the best theory of light and electrons (and therefore chemistry and material science) that we have today, quantum electrodynamics, is a quantum field theory.
A vortex (plural: vortices) is a flow pattern characterized by a rotating, swirling motion of fluid (which can be gas or liquid) around an axis. Vortices can occur in many different contexts, including in nature, engineering, and physics. Some key characteristics of vortices include: 1. **Rotation**: The fluid moves in a circular or spiral path around a central core or axis. The speed and direction of rotation can vary.

Capoeira music is amazing. And some Brazilian pop adaptations of it have also been awesome.

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.
