The most basic non-trivial differential one-form is the "change in angle" form . This is defined as the derivative of the angle "function" θ ( x , y ) {\\displaystyle \\theta (x,y)} (which is only defined up to an additive constant), which can be explicitly defined in terms of the atan2 function.
In golf, a hole in one or hole-in-one occurs when a ball hit from a tee to start a hole finishes in the cup. The feat is also known as an ace, mostly in American English.As the feat needs to occur on the stroke that starts a hole, a ball hit from a tee following a lost ball, out-of-bounds, or water hazard is not a hole-in-one, due to the application of a stroke penalty.

The United States Golf Register is the United States's official historical registry of holes-in-one. The U.S. Golf Register is devoted to preserving history with each hole-in-one made, and recording the significance of the achievement as a historical record. There are no registration fees or dues associated with registering.
Dirac hole theory is a theory in quantum mechanics, named after English theoretical physicist Paul Dirac, who introduced it in 1929. [1] The theory poses that the continuum of negative energy states, that are solutions to the Dirac equation, are filled with electrons, and the vacancies in this continuum (holes) are manifested as positrons with energy and momentum that are the negative of those ...
In addition to being used as food, corn is a source of ethanol fuel, and the NCGA has provided standards and guidelines for farmers growing ethanol. [4]The NCGA has also advocated for continued support and subsidies from the United States government for the ethanol fuel program, citing studies on the benefits for fighting climate change of switching away from fossil fuels towards ethanol.
