Can a magnetic monopole exist? As implied by its name, the magnetic monopole consists of a single pole, as opposed to the dipole, which is comprised of two magnetic poles. As yet there is no evidence for the existence of magnetic monopoles, but they are interesting theoretically. Are there magnetic charges? This is the principle […]

Is differential equations the hardest math class? Even though there are some aspects of differential equations that can be difficult, overall, I would say that differential equations are actually one of the easier higher level math classes. In addition, differential equations do not tend to be as proof heavy as other higher level math classes. […]

Can fluorine have a double bond? In this structure with a double bond the fluorine atom is sharing extra electrons with the boron. The fluorine would have a ‘+’ partial charge, and the boron a ‘-‘ partial charge, this is inconsistent with the electronegativities of fluorine and boron. Is Iodine a double bond? In fatty […]

Why do we feel hot under tungsten bulb? So hot, in fact, that it gives off enough energy to cause the filament to glow. This is the same reason that the cooking elements on an electric stove glow red when they heat up. Did you know? The tungsten filament in an incandescent light bulb heats […]
