Hel
In Norse mythology, Helheim, the location, means "house of Hel." It was the abode of Hel, a female figure who ruled the Underworld in Norse Mythology. In late Icelandic sources, varying descriptions of Hel are given and various figures are described as being buried with items that will facilitate their journey to Hel after their death. In the Poetic Edda, Brynhildr's trip to Hel after her death is described and Odin, while alive, also visits Hel upon his horse Sleipnir. In Snorri Sturluson's Prose Edda, Baldr goes to Hel upon death and subsequently Hermóðr uses Sleipnir to attempt to retrieve him. "Hel-shoes" are described in Gísla saga.
Cadaver Synod
The Cadaver Synod (also called the Cadaver Trial or, in Latin, the Synodus Horrenda) is the name commonly given to the posthumous ecclesiastical trial of Catholic Pope Formosus, held in the Basilica of St. John Lateran in Rome during January of 897.
Before the proceedings the body of Formosus was exhumed and, according to some sources, seated on a throne while his successor, Pope Stephen (VI) VII, read the charges against him (of which Formosus was found guilty) and conducted the trial. The Cadaver Synod is remembered as one of the most bizarre episodes in the history of the medieval papacy.

Gravitational slingshot
In orbital mechanics and aerospace engineering, a gravitational slingshot, gravity assist maneuver, or swing-by is the use of the relative movement and gravity of a planet or other celestial body to alter the path and speed of a spacecraft, typically in order to save propellant, time, and expense. Gravity assistance can be used to accelerate, decelerate and/or re-direct the path of a spacecraft.
The "assist" is provided by the motion (orbital angular momentum) of the gravitating body as it pulls on the spacecraft.The technique was first proposed as a mid-course manoeuvre in 1961, and used by interplanetary probes from Mariner 10 onwards, including Voyagers' notable fly-bys of Jupiter and Saturn.

Orbital mechanics
Orbital mechanics or astrodynamics is the application of ballistics and celestial mechanics to the practical problems concerning the motion of rockets and other spacecraft. The motion of these objects is usually calculated from Newton's laws of motion and Newton's law of universal gravitation. It is a core discipline within space mission design and control. Celestial mechanics treats more broadly the orbital dynamics of systems under the influence of gravity, including both spacecraft and natural astronomical bodies such as star systems, planets, moons, and comets. Orbital mechanics focuses on spacecraft trajectories, including orbital maneuvers, orbit plane changes, and interplanetary transfers, and is used by mission planners to predict the results of propulsive maneuvers. General relativity is a more exact theory than Newton's laws for calculating orbits, and is sometimes necessary for greater accuracy or in high-gravity situations (such as orbits close to the Sun).
Tehnocracy
Technocracy is a form of government in which engineers, scientists, health professionals and other technical experts are in control of decision making in their respective fields. The term technocracy derives from the Greek words tekhne meaning skill and kratos meaning power, as in government, or rule. Thus the term technocracy denotes a system of government where those who have knowledge, expertise or skills compose the governing body. In a technocracy decision makers would be selected based upon how highly knowledgeable they are, rather than how much political capital they hold.
Technocrats are individuals with technical training and occupations who perceive many important societal problems as being solvable, often while proposing technology-focused solutions. The administrative scientist Gunnar K. A. Njalsson theorizes that technocrats are primarily driven by their cognitive "problem-solution mindsets" and only in part by particular occupational group interests. Their activities and the increasing success of their ideas are thought to be a crucial factor behind the modern spread of technology and the largely ideological concept of the "Information society." Technocrats may be distinguished from "econocrats" and "bureaucrats" whose problem-solution mindsets differ from those of the technocrats.
In all cases technical and leadership skills are selected through bureaucratic processes on the basis of specialized knowledge and performance, rather than democratic election by those without such knowledge or skill deemed necessary. Some forms of technocracy are a form of meritocracy, a system where the "most qualified" and those who decide the validity of qualifications are the same people. Other forms have been described as not being an oligarchic human group of controllers, but rather an administration by science without the influence of special interest groups.

Erase a CD with High Voltage
One enterprising individual has created the most secure way to wipe out Compact Discs, by using a step-up transformer and creating a 150,000 Volt pd, whilst a CD rotates in the middle. The sparks arc through the metal in the CD and evaporates it, ripping it all off as the CD rotates. The CD is rendered transparent and unreadable. This may be the most secure method to remove data on conventional recordable CDs used in offices.
Bone Conduction
Bone conduction is the conduction of sound to the inner ear through the bones of the skull.
Bone conduction is the reason why a person's voice sounds different to him/her when it is recorded and played back. Because the skull conducts lower frequencies better than air, people perceive their own voices to be lower and deeper than others do.[1][2] This also explains why a recording of one's own voice sounds higher than one is accustomed to.

Leet
Leet (or "1337"), also known as eleet or leetspeak, is an alternative alphabet for the English language that is used primarily on the Internet. It uses various combinations of ASCII characters to replace Latinate letters. For example, leet spellings of the word leet include 1337 and l33t; eleet may be spelled 31337 or 3l33t.
The term leet is derived from the word elite. The leet alphabet is a specialized form of symbolic writing. Leet may also be considered a substitution cipher, although many dialects or linguistic varieties exist in different online communities. The term leet is also used as an adjective to describe formidable prowess or accomplishment, especially in the fields of online gaming and in its original usage, computer hacking.

Verona Rupes: Tallest Known Cliff in the Solar System
Could you survive a jump off the tallest cliff in the Solar System? Quite possibly. Verona Rupes on Uranus' moon Miranda is estimated to be 20 kilometers deep -- ten times the depth of the Earth's Grand Canyon. Given Miranda's low gravity, it would take about 12 minutes for a thrill-seeking adventurer to fall from the top, reaching the bottom at the speed of a racecar -- about 200 kilometers per hour. Even so, the fall might be survivable given proper airbag protection. The above image of Verona Rupes was captured by the passing Voyager 2 robotic spacecraft in 1986. How the giant cliff was created remains unknown, but is possibly related to a large impact or tectonic surface motion.
Despre viata
“Un lung tren ne pare viaţa.
Ne trezim în el mergând,
Fără să ne dăm noi seama,
Unde ne-am suit şi când.
Fericirile sunt halte,
Unde stăm cât un minut,
Până bine ne dăm seama,
Sună, pleacă, a trecut.
Iar durerile sunt staţii
Lungi, de nu se mai sfârşesc
Şi în ciuda noastră parcă,
Tot mai multe se ivesc.
Arzători de nerăbdare,
Înainte tot privim,
Să ajungem mai degrabă
La vreo ţintă ce-o dorim.
Ne trec zilele, trec anii,
Clipe scumpe şi dureri,
Noi trăim hrăniţi de visuri
Şi-nsetaţi după plăceri.
Mulţi copii voioşi se urcă.
Câţi în drum n-am întâlnit,
Iar câte un bătrân coboară,
Trist şi frânt, sau istovit.
Vine-odată însă vremea,
Să ne coborâm şi noi.
Ce n-am da atunci o clipă,
Să ne-ntoarcem înapoi?
Dar pe când, privind în urmă,
Plângem timpul ce-a trecut,
Sună goarna VEŞNICIEI:
< Am trăit şi n-am ştiut > “

Meteors
After midnight, the only meteoroids escaping collision are those ahead of the Earth and moving in the same direction with velocities exceeding 18.5 miles per second (30 kilometers per second). All others we will either overtake or meet head-on.
But before midnight, when we are on the back side, the only meteoroids we encounter are those with velocities high enough to overtake the Earth. Therefore, on average, morning meteors appear brighter and faster than those we see in the evening.
And because the Leonids are moving along in their orbit around the sun in a direction opposite to that of Earth, they slam into our atmosphere nearly head-on, resulting in the fastest meteor velocities possible: 45 miles per second (72 kms). Such speeds tend to produce bright meteors, which leave those aforementioned long-lasting streaks or trains in their wake.
Also, as Leo is beginning to climb the eastern sky near and before midnight, there is a small chance of perhaps catching sight of an "Earth-grazing" meteor.
Earth-grazers are long, bright shooting stars that streak overhead from near to even just below the horizon. Earth-grazers are distinctive because they follow a path nearly parallel to our atmosphere.
