Historian Nile Green (UCLA) describes how the model of religious economy is relevant to Iran.

Index theory is a method used to gain global information about a nonlinear differential equation. One powerful insight is that closed orbits (periodic solutions) must have at least one fixed point inside of the curve. In fact, for a...

This video explores five fun facts about black history.

Heisenberg’s uncertainty principle says that if we know everything about where a particle is located, we know nothing about its momentum. Conversely, if we know everything about its momentum, then we know nothing about where the particle...

The video discusses the essential quantitative skills that modern-day economists should possess to successfully handle and interpret data and statistics related to economies, trade figures, and budget figures. The video goes over various...

The rocket part crashing toward the Moon is not the upper stage of a SpaceX Falcon 9, it is most likely to be part of the Long March 3C rocket that launched China's moonbound Chang'e 5-T1 mission.

How is mechanical energy and the conservation of energy alike? What is the formula for mechanical energy?<br/>

MOT 1953: FILMING ROCKET FLIGHT: 60 Miles above Earth rocket begins to spin, VS Spinning space & land, FREEZE FRAME at 76 miles above Earth. (NASA uses 76 as space begins, actullay begins at 73)

In this video, I discuss how hard pitchers should throw a curveball relative to their fastball speed.

A curveball is a type of breaking ball that has a sideways or downward motion. When the pitcher releases the ball, the stitching on the leather causes pressure on one side of the ball to be greater than on the other side. This imbalance...

OSIRIS-REx Principal Investigator Dante Lauretta discusses the NASA mission to near-Earth asteroid Bennu.

Is throwing a get-me-over curveball ever a good move?

Observatories including NASA’s Hubble Space Telescope found that the interstellar object named ‘Oumuamua gained an extra boost of speed, which likely comes from comet-like jets of gas.Credit: NASA’s Goddard Space Flight...

Learn how to add and/or subtract rational expressions. A rational expression is an expression in the form of a fraction where the numerator and/or the denominator are/is an algebraic expression. When adding or subtracting rational...

On September 25, 2135, an asteroid called Bennu will make a close flyby of Earth. Our planet’s gravity will tweak Bennu’s path, making it a challenge to calculate its future trajectory. During the flyby, there is...

Earth’s so-called “second moon” will make one final pass this week before floating out into space forever.

101955 Bennu is one of Earth’s closest planetary neighbors – an asteroid roughly the height of a skyscraper, and since late 2018, the place that NASA’s OSIRIS-REx mission has called home. When OSIRIS-REx arrived on...

Lucy is the first mission to explore the Jupiter Trojans – two swarms of asteroids that share Jupiter’s orbit, leading and trailing the giant planet by sixty degrees. These primitive bodies are thought to be...

OSIRIS-REx is the third mission in NASA's New Frontiers Program. Its goal is to explore near-Earth asteroid Bennu, a...

This video is answering the question of who was Katherine Johnson.

If an Earth-bound asteroid was seen with only six months’ warning, a group of scientists from NASA and other space agencies has concluded that no-one could do anything to stop it hitting the planet, according to Business Insider.

Look up to the night sky just before dawn, or after dusk, and you might see a faint column of light extending up from the horizon. That luminous glow is the zodiacal light, or sunlight reflected toward Earth by a cloud...

Since arriving at near-Earth asteroid Bennu in December 2018, NASA's OSIRIS-REx mission has been studying this small world of boulders, rocks, and loose rubble - and looking for a place to touch down. The goal of OSIRIS-REx...

Discover the mysteries of the solar system through the eyes of the Lucy mission and its team members. This fourth episode features Lucy Flight Navigator Coralie Adam, who discusses how the team directs Lucy...
