👉 Learn how to sketch angles in terms of pi. An angle is the figure formed by two rays sharing the same endpoint. Angle is measured in radians or in degrees. One complete revolution about a point is equivalent to 2pi radians and 360...

On this episode of Blue Wilderness, Mark and the crew are in Stingray City just 35 minutes off the coast of Grand Cayman.. and they’re going diving with Stingrays to find the Sting King of the deep! Lets hope they don’t get stung or...

In this video, the presenter discusses the interaction between electromagnetic waves and charged particles. The video covers examples of radio waves interacting with electrons and how they can create alternating currents in appropriate...

Learn how to name angles.

👉 Learn all about angles of trigonometry. In this playlist, we will explore what makes up an angle and how to graph an angle in degrees or radians to determine the quadrant. We will then take a look at angle relationships such as...

Neutron stars are formed from the core of some starrs. Neutron stars generally have a radius of only around 12 km. With masses exceeding 1.4 times that of the Sun, these are some of the densest objects in the Universe. A tablespoonful of...

A body scanner is a security device used in commercial airlines to detect metallic and non-metallic threats. There are two types of scanners, one using X-rays and the other using millimeter wave technology. Understand the differences...

👉 Learn about angles in trigonometry. An angle is the figure formed by two rays sharing the same endpoint. The two rays are called the sides of the angle while the common endpoint of the two rays is called the vertex of the angle. Angle...

👉 Learn how to define angle relationships. Knowledge of the relationships between angles can help in determining the value of a given angle. The various angle relationships include: vertical angles, adjacent angles, complementary angles,...

Definition and how to learn radiological anatomy.

On Sept. 16, NASA's Swift satellite detected a rising tide of high-energy X-rays from a source toward the center of our Milky Way galaxy. The outburst, produced by a rare X-ray nova, announced the presence of a previously...

O-type stars are among the most massive and hottest known, pounding their surroundings with intense ultraviolet light and powerful outflows called stellar winds. NASA's Swift and ESA's XMM-Newton X-ray observatories took part in a...
