In physics, the Lorentz transformations (or transformation) are coordinate transformations between two coordinate frames that move at constant velocity relative to each other. The transformations are named after Hendrik Lorentz, a Dutch physicist in electrodynamics.
The most common form of the transformation is expressed as:
where (t, x, y, z) and (t′, x′, y′, z′) represent an event’s coordinates in two frames with relative velocity v, c is the speed of light, and the Lorentz factor:
Judges of the Dead
RHADAMANTHYS, MINOS and AIAKOS (Aeacus) were the judges of the dead, three demi-god ministers of Haides. They were originally mortal men, sons of the god Zeus, who were granted their station in death as a reward for establishing law and order on earth.
Individually, Aiakos was guardian of the keys of Haides and judge of the men of Europe, Rhadamanthys the lord of Elysion (Elysium) and judge of the men of Asia, and Minos the judge of the third and final vote. According to some Triptolemos was a fourth judge who presided over the souls of Initiates of the Mysteries.
The name Aiakos was derived from the Greek words aiaktos and aiazô, “wailing” and “lamentation.” The etymology of the other names is obscure.
The mortal lives of the three judges is not detailed on this page only their role in the afterlife.

Aeacus and Telamon by Jean-Michel Moreau le Jeune.
Aeacus (or Aiacos; Greek: Αἰακός) was a mythological king of the island of Aegina in the Saronic Gulf.
Aeacus was the son of Zeus and Aegina, a daughter of the river-god Asopus. He was the father of Peleus, Telamon and Phocus and was the grandfather of Achilles (son of Peleus) and Ajax (son of Telemon).
Aeacus was born on the island of Oenone or Oenopia, where Aegina had been carried by Zeus to secure her from the anger of her parents; afterward, this island became known as Aegina. Some stories related that, at the time when Aeacus was born, Aegina was not inhabited, and that Zeus either changed the ants (μύρμηκες) of the island into the men (Myrmidons) over whom Aeacus ruled, or he made the men grow up out of the earth. Ovid, on the other hand, Continue reading
The hieroglyphic sign for “mountain” depicted to peaks with a valley running between them. This image approximated the hills that rose up on either side of the Nile valley.
Although the djew hieroglyph did portray the mountain ranges the Egyptians saw in their everyday lives, it also was a visualization of their cosmic beliefs. Symbolically, the “mountain” was an image of the universal mountain whose two peaks were imagined to hold up the sky. The eastern peak was called Bakhu, to the west was Manu. The ends of this great mountain were guarded by two lions who were called Aker. Aker was a protector of the the sun as it rose and set each day. Continue reading
From Book of Silence – Sepher Hash’tikah
by Reb Yakov Leib HaKohain, DONMEH WEST
“In seeking Wisdom, the first stage is silence.” — Rabbi Solomon ibn Gabriol (11th Century)
To begin with, there are two Silences and not one: There is the Silence of the Mouth and, in addition, the Silence of the Mind. The former does not necessarily accompany the latter, but the latter always accompanies the former. That is, one can be silent “in-the-mouth” while not, at the same time, also being silent “in-the-mind.” On the other hand, one who is silent “in-the-mind” is, at the same time, always silent in-the-mouth. Thus, there are three types of Lomaidim (Hebrew = “Learners”):
- THE FOOL: Silent neither in the Mouth nor Mind
- THE HEARING IMPAIRED: Silent in the Mouth but not the Mind
- THE LISTENER: Silent in the Mouth and the Mind
Of the “fool,” Buddhism says, “A fool is like a spoon: it can sit in a bowl of soup forever and never taste it.” And in much the same way, the Talmud teaches: Continue reading
a structure in replicating circular DNA.
Synonym(s): displacement loop
Farlex Partner Medical Dictionary
A Box – A highly conserved (i.e., the DNA nucleotide sequence is similar among many eukaryotic species) region located between base pairs +10 and +20 “upstream” on the tRNA gene, which have the dual role of encoding functional tRNA and promoting tRNA transcription, and acting as a site of receptive protein binding.
