A Newtonian demonstrator is also called the "Newton's Cradle" and is sold as an office desk toy. It comes in a dramatic range of sizes and shapes, as you can see. The Geek Group in Kalamazoo makes the giant size.
Ever have a hard time falling asleep at night, but don't want to turn on the lights to do some reading? If you enjoy thinking about the universe, these thought experiments will blow your mind.
This is part 1 of a 5 part hands-on unit study on Floating & Flying (Fluid Mechanics). This week's focus is buoyancy (floating). Build an aluminium foil barge that can hold the most pennies, experiment with what floats and sinks and why, explore the relationship between density and buoyancy, and...
What Is an Object? People often use the word “object” without having a clue what it means. Physics is the study of objects; real objects which are said to exist. Physics does not study something which cannot possibly exist. But...
Starting with a tricky challenge of catching a bill we will discuss the physics of free fall. The intrigued fact whether the free fall depend on body mass or not dates back to the Galileo Galilei's experiments within the Leaning Tower of Pisa. The article addresses a rather comprehensive study of...
General Relativity sweeps the troublesome Mach's Principle under the rug and has no explanation for the complex units of the gravitational constant G. On the other hand, the rope hypothesis justifies Mach's Principle and at least two factors of the gravitational constant.
A quick look at the evolution of the home lightbulb from the late 1800s to the present. The advantages and disadvantages of each type of lightbulb is discussed and how each type produces light.
Both of these are used frequently in astronomical work but the differences between them help us learn more about their sources.
John Tyndall, a one-time railway surveyor, made himself one of the most prominent physicists of nineteenth-century Britain. But today he's remembered best for his discovery of the mechanism of the greenhouse effect. Read about his remarkable life and work here.
The God Particle, more properly known as the Higgs Boson has been positively identified as existing in the real world. This is a monumental step forward in Man's understanding of who and what we are.
