Private foundation is an institution with a very special status. They are tax exempt private organizations yet they are still allowed to invest into for profit companies. Foundations can hold corporate stocks and bonds and generate revenue this way.

There is only one major condition they have to fulfill to keep their tax exempt status - and that is to donate 5% of foundation's total assets on annual basis. So when you hear a billionaire donating their wealth to charity and it's going through a foundation, up to 95% of it can go into profitable investments. In practice, all foundations' assets in the US amount to more than $1 trillion. Yet, they donated only $90.88 billion in 2021.

"Çatalhöyük: a 9000 year old town"

Relatore: Ian Hodder (Professor of Anthropology, Stanford University)
Project Director of Çatalhöyük Research Project (www.catalhoyuk.com)

Abstract
This talk describes the fascinating and important early town of Çatalhöyük in central Turkey. The site is important because of its large size and elaborate symbolism, including wall art and burials beneath the floors of houses. The speaker has been excavating at the site for 25 years using the latest scientific techniques. A very large team has been piecing together the detailed evidence of the site in order to understand how the society was organized, how it lasted so long, and what its rich symbolism means.

MindMetricsHub

Hello, everyone hope you all are having a nice day, i and a couple of my colleagues have made a discord server called MindMetricshub, we are a community that hope to foster knowledge sharing and discussion centered around human cognition, 2 of our members are currently norming some cognitive tests and one of them is hoping to create an assessment of g that's based primarily on games. We also offer about 7 different cognitive psychometric instruments namely:

Wechsler Adult intelligence scale fourth edition (WAIS-IV)

Stanford Binet Fifth Edition (SB-V)

Wechsler Abbreviated Scale of Intelligence (WASI-2)

Reynolds Adaptive Intelligence Test (RAIT)

Kaufmanns Brief Intelligence Test - Second Edition Revised

Ravens 2 and PPVT-5 (from Pearson Q-global)

all these can be administered for a fraction of what they originally cost (this is our attempt to raise some revenue lol)If you are interested please join our server link below ( when you initially join there would be limited access to features in the server please be patient we will grant you access within a short time)

Snake's tongue has two sensitive tips, called tines, which help the snake smell in stereo.

This video, a scientific visualization of the galaxies captured as a part of the CEERS (Cosmic Evolution Early Release Science) Survey, showcases a large undertaking by NASA’s James Webb Space Telescope. It flies by thousands of galaxies, starting with those nearby and ending with less-developed galaxies in the very distant universe, including one never seen before Webb.

Linguistics professor Daniel Everett explains the idea of "xibipiio," a way of life he encountered while studying the language of the Amazonian Piraha tribe. Everett, a former Christian missionary, was challenged to rethink his faith after learning the Piraha's concept of experiential liminality.

Von Kármán vortices streaming around Guadalupe Island.

Beautiful vortices in the wake of an F-15 pulling Gs, when the parallel vortices break down due to Crow instability, they break off into rings (toroidal vortices).

A whale fall occurs when the carcass of a whale has fallen onto the ocean floor at a depth greater than 1,000 m (3,300 ft), in the bathyal or abyssal zones. On the sea floor, these carcasses can create complex localized ecosystems that supply sustenance to deep-sea organisms for decades. Wiki

Superconducting material can become pinned in place above a neodymium magnet. When those magnets are arranged in a track, the superconductor can follow that track even if it has loops and corkscrews.

After the right and left brain are separated, each hemisphere will have its own separate perception, concepts, and impulses to act. Having two "brains" in one body can create some interesting dilemmas.

Some basic quantum mechanics, the double slit experiment and why we don't see quantum effects in macroscopic objects like a tennis ball.

An analog computer uses the continuous variation aspect of physical phenomena such as electrical, mechanical, or hydraulic quantities (analog signals) to model the problem being solved.

The many-worlds interpretation is an interpretation of quantum mechanics that asserts that the universal wavefunction is objectively real, and that there is no wave function collapse.
This implies that all possible outcomes of quantum measurements are physically realized in some "world" or universe.
