Many people today deny the reality of original sin. Modern thinkers claim that evolution disproves it. Some object to the idea of inheriting sin from our parents, while others simply deny sin itself.

Abstract: This paper presents an absolute capacitive rotary encoder using a sample-and-hold demodulator (SHD) to reduce interference between sine and cosine channels. The capacitive encoder measures ...

The sides of right-angled triangles are labelled opposite, hypotenuse and adjacent. Trigonometry explores the relationship between sides and angles in right-angled triangles. The hypotenuse is the ...

The Language of the Universe: The description of mathematics as the "language of the universe" is profoundly fitting, reflecting its position as the unseen, pervasive thread that ties the cosmos and ...
