“It’s Friday” is a theory of temporal physics that was invented in March 2011. Published by Rebecca Black with fellow colleagues Clarence Jay and Patrice Wilson, the work is widely believed to be announced as a nomination the Nobel Prize in physics for 2011. The current title is not the original; it was changed in order to create a larger appeal to the relatively uneducated public, who are unconcerned with most theoretical physics. The original title for the theory was “The time differentiation paradigm: an explanation of temporal shifts in the Earth’s rotation patterns”. The paper makes several breakthroughs in various fields, including seat selection theory, time establishment theory and provides a prediction model for assessing time in the future valid for up to 48 hours.
