How to Read LIM in Calculus
As in any language, there are conventions of expression and meaning in mathematics that might seem strange at first but that quickly become both useful and familiar. The term limit (lim) is one such conventional method. French mathematician Augustin-Louis Cauchy (1789-1857) proposed the first modern
What Are the Three Types of Energy That Take Place in a Water Turbine?
Water turbines have been used for centuries as a means to produce energy. A common waterwheel uses falling water and rotating blades to drive a shaft; the rotating shaft can be used for any purpose depending upon need or application. Forces and energies must act upon a turbine to make it work, which
How to Search for Irish Genealogy

Indirect Development vs. Direct Development
Direct and indirect development are terms that describe different processes of animal development. Animal development begins with a fertilized egg. The difference between direct and indirect development lies chiefly in the progression through the juvenile phase of life. The path from conception to a
How to Remove Glue From Baseboards
From super glue to fabric adhesive, removing stubborn glue stains from a baseboard requires using heat to soften the chemical compound. As glue dries, it hardens, making prying it from any surface difficult. Removing glue from a painted or unpainted baseboard requires the same procedure, although pa
How to Make Bottle Cap Spurs
