The story about the Tesla Egg of Columbus…There is a legend about Christopher Columbus winning a wager against his critics by making an egg stand on its tip. That story is often used to illustrate the fact that it is often simple to understand the discovery after it already happened. That principle is certainly true in case of famous inventor Nikola Tesla who discovered principles of rotating (rotary) magnetic field. His discoveries lead to the invention of the polyphase induction motor. Although Tesla didn’t discover alternating current, he was the first one to effectively harness it and use it to do useful work.
Germination of plant seed is normally affected by ambient temperature, moisture, pH of soil, lighting conditions and quality of seed. Usually only a certain percentage of seed successfully germinates and develops into seedlings. It is less known that certain oscillating electromagnetic fields also affect germination rate and the growth of seedlings and their later growth into fully developed plants. Effects of electromagnetic fields on the germination of seed, seedling development and later plant growth can be beneficial or detrimental, depending on the nature of electromagnetic fields and the way they are applied.
Zeolites are crystalline hydrated aluminosilicate minerals of alkali and alkaline earth cations. They have infinite, three dimensional structures. Naturally occurring zeolites are very good absorbents so they have many particular uses in agriculture, animal farming, human medicine, veterinary medicine, cosmetics, environmental protection, industrial applications etc.
