Exploring the Core: Basic Solid Properties

Solids diffuse slowly compared to liquids and gases, as constituent particles are closely packed, allowing little space for movement. They have a higher density than gases and liquids....

Could King Kong ever evolve to exist? Could we simply scale up a gorilla? How and where could this giant ape develop? Join us as we explore the science behind the king of monsters!

This case study is a comparison between well-presented and poorly presented evidence. In this scenario, the expert is being asked about his investigation of a boat’s sinking rate. As part of the examination in chief, the expert is asked...

Maximizing Space: The Science of Packing Efficiency"

Packing efficiency, also known as packing fraction or atomic packing factor, is a measurement of how efficiently atoms or particles are packed in a crystal structure. Magnetic...

What Parker Solar Probe Heard Around the Sun.

Dr. Boyd gives the physics definition of density, then walks you through a demonstration to show how liquids with different densities can form multiple liquid layers in a container.

We explore the fundamental nature of entropy and its deep link to information. If you were taught that entropy measured disorder, you are in for a treat!

Cybersecurity firm Crowdstrike pushed an update that caused millions of Windows computers to enter recovery mode, triggering the blue screen of death. Learn how the Crowdstrike crash happened and its impact around the world. Topics...

How much of an effect would a second Sun have on Earth? Is there a way it could work?

The decibel is used to measure sound levels. It is represented by dB and is widely used in signals, communication, and electronics. The term decibel can be used to express an absolute value or a change in value (+1 dB or -1 dB). Decibels...

The respiratory system is composed of the nose or nasal cavity, the pharynx, the larynx, the trachea, the bronchi, and the lungs. The respiratory system's functions are gaseous exchange, inhaling oxygen and exhaling out carbon dioxide,...

Yes, water expands when it freezes. Note that the word expands here indicates an increase in volume. So, a technically sound way to put it would bewaters volume increases when it freezes. This statement is accurate, and you can test its...

Humidity is simply a measure of how "wet" the air is in a specific place, or the amount of water vapor present in the air. However, it's important to note that humidity is an umbrella term that can refer to three different types of...

Contrary to popular belief (as set by movies), cars are not very prone to explosions, and even a car that is on fire is very unlikely to explode. The necessary conditions for an explosion to take place are not met after a car experiences...

In this video transcript, Nova takes children on a galactic adventure to discover the values of peace and harmony. Through the metaphor of baking a cake, she emphasizes the importance of communication, respect, and compromise in...

Science fiction films like 'The Fly' and 'Mothra' will show you giant insects creating havoc and destroying world order with their giantness. But, is that even possible? Science says, not really. When the insect's exoskeleton expands it...

Discover the forces at work underwater, which dictate why large boats float but small pebbles sink. Physics - Forces - Learning Points. The buoyant force is an upward-acting force determined by the weight of the displaced water. Ships...

Hot air balloons rely on heat alone to keep them in the sky. How does this work? Physics - Energy And Radioactivity - Learning Points. Hot air rises in cool air because it is less dense. The hot air within a hot air balloon creates the...
