There are many churches claiming to have fragments of the True Cross. It is believed that the cross was lost until Constantine’s mother Empress Helena traveled to the Holy Land in search of religious relics in 326-328. She traveled to the place where Jesus was said to have been crucified to discover that a temple had been built over it. Helena ordered that the temple be destroyed and the dirt beneath the temple removed. Continue reading The True Cross→
According to an in-depth study performed in 1999, there are three types of hallucinations that can occur during sleep paralysis: “incubus”, “intruder”, and “unusual bodily experiences”.
People feel intense pressure on their chests and they feel they cannot breath. However, this is only a mental game. It feels like they can’t breath because they are afraid. Also, the body is still in REM breathing mode which is very shallow. It would seem strange to anyone. Continue reading Different Types of Sleep Paralysis→
The Earth orbits the Sun once a year in a nearly circular orbit.
The Earth’s axis of rotation (the straight line through the center of the Earth between the north and south poles) is not perpendicular to the plane of the Earth’s orbit. The Earth’s axis is tilted by about 23.4° from the the direction perpendiular to the orbital plane.
The orientation of the Earth’s axis in space remains nearly constant even as the Earth revolves around the Sun. It always points in the general direction of the star Polaris. Continue reading The Earth’s seasons→
“I fear the plutocracy of wealth, I respect the aristocracy of learning, but I thank God for the democracy of the heart that makes it possible for every human being to do something to make life worth living while he lives and the world better for his existence in it.” ~Wiliiam Jennings Bryan
In 1954, the tenth general conference on weights and measures adopted the Kelvin K as the basic unit for measuring all international weights and measures. While the kelvin is the standard unit, degrees Farenheit and degrees Celsius are still in common use in the United States.
The function C(F)=5/9(F-32) relates Celsius temperatures and Farenheit Temperatures. The function K(C)= C + 273.15 relates celsius temperatures and kelvin temperatures.
Let’s convert Fahrenheit to Kelvin. The composition of the function K with the function C is
K(C(F)) = C(F) + 273 = (5/9)(F-32) + 273
Since C converts Fahrenheit to Celsius and K converts Celsius to Kelvin, the composition will convert Fahrenheit to Kelvin.
