A pendulum with a length of 1 meter has a period of about 2 seconds (so it takes about 1 second to swing across an arc). This means that there is a relationship between the gravitational field (g) and Pi.
Once the weighted end of the pendulum is released, it will become active as gravity pulls it downward. Potential energy is converted to kinetic energy, which is the energy exerted by a moving object.
Because each swing of a pendulum takes it from a point farther from the equator to a point nearer to the equator and vice versa, and the velocities at these points differ, the path of the pendulum is subtly distorted with every swing, gradually torqued away from its original orientation.
A pendulum is a simple example of energy transfer – converting potential energy to kinetic energy over and over until the small amount of energy lost to heat and air resistance causes the pendulum to come to rest.
The escapement is a mechanical linkage that converts the force from the clock's wheel train into impulses that keep the pendulum swinging back and forth. It is the part that makes the "ticking" sound in a working pendulum clock.
Different types of healing crystals
- Clear quartz. This white crystal is considered a “master healer.” It's said to amplify energy by absorbing, storing, releasing, and regulating it.
- Rose quartz. Just as the color may suggest, this pink stone is all about love.
- Jasper.
- Obsidian.
- Citrine.
- Turquoise.
- Tiger's eye.
- Amethyst.
The resultant force is the force that results from the combination of two or more forces. The two forces that act on the pendulum are the force of gravity, pulling straight down, and the force by the pivot, pulling along the string, towards the pivot.
Such was the case with 17th century Dutch astronomer Christiaan Huygens. He became the first to report the phenomenon of coupled oscillation in two pendulum clocks (which he invented) in his bedroom while recovering from an illness in 1665. : being or resembling the movement of a pendulum.
Through the pendulum, Galilei discovered isochronisms, the pendulum's most important characteristics, which make them useful in measuring time.
Radius of gyration or gyradius of a body about the axis of rotation is defined as the radial distance to a point which would have a moment of inertia the same as the body's actual distribution of mass, if the total mass of the body were concentrated there.
A simple way to measure the pendulum's period fairly precisely is to start the pendulum swinging, and measure the time required for a large number of FULL swings - 40, 50, or so. Choose the number of swings so that the total time for the measurement is 40 seconds or more.
were then used to study the effects of varying the weight distribution, wheelbase, and incorporating a suspension. A third example of the compound pendulum method of measuring weight distribution is its application to sail- boats. The total weight of a sailboat has a major effect on its speed.
Dowsing is a pseudoscience, and the scientific evidence is that it is no more effective than random chance. Dowsers often achieve good results because random chance has a high probability of finding water in favourable terrain.
The bottom or butt end of the "Y" is pointed skyward at an angle of about 45 degrees. The dowser then walks back and forth over the area to be tested. When she/he passes over a source of water, the butt end of the stick is supposed to rotate or be attracted downward.
How to cleanse your crystals
- Put them outside or on a windowsill on a full moon to recharge.
- Use the rain as a way to cleanse them with water, or soak them in a bowl of salt water.
- Smudge them with a sage stick or some palo santo.
- Bury them underground for 24 hours.
- Use a cleansing crystal.
Moldavite (Czech: Vltavín) is a forest green, olive green or blue greenish vitreous silica projectile rock formed by a meteorite impact probably in southern Germany (Nördlinger Ries Crater) that occurred about 15 million years ago. It is a type of tektite.
If you're near the ocean, consider collecting a bowl of fresh salt water. Otherwise, mix a tablespoon of sea, rock, or table salt into a bowl of water. Make sure that your stone is completely submerged, and allow it to soak for a few hours to a few days' time. Rinse and pat dry when complete.
