Sarah Wilson Although a common symbol throughout history, the lightning bolt has a deep, Biblical link to Lucifer himself. The ancient myths that Romans, Greeks and other early civilizations worshipped came from a belief in a spirit world, where gods and goddesses possessed both human-like qualities and sub-human powers. A handful of the gods relied on the power of the lightning bolt to threaten, scare or punish the mortals on Earth. One of the most powerful of Greek gods was Zeus, and his weapon of choice was the lightning bolt or the double bolt. Throughout history, the double lightning bolt has been used in many different forms. One of the most negative uses of this symbol is associated with the Nazi Germans, who heavily used the double lightning bolt in their propaganda, emblems and pendants.

Sad irons, also called flat irons or smoothing irons, are shaped pieces of metal that are flat and polished on one side and have a handle attached to the other, created for the purpose of de-wrinkling fabric.
Posted on March 23, by The Physicist Physicist: Nuclear reactors are very 19th century in a way. The nuclear fuel is basically a bunch of very hot metal, and the more of it you get together in one place, the hotter it gets. That heat is used to turn water into steam, which turns turbines. Uranium and plutonium nuclear fuel undergo radioactive decay on their own, at random. This is the base radioactive rate. As luck would have it, when uranium and plutonium decays it generates a spray of neutrons, and can induce nearby material to decay as a result.
In a reactor, the average number of other atoms set off by each decaying atom is less than one. This means that the rate of radioactive decay levels out at a relatively low level. The base radioactive rate the random decays keeps the rate from dropping all the way to zero. However, if the average is more than one, then the rate of decay will keep increasing exponentially.

A lightning rod or lightning conductor is an iron rod that is used to make lightning strike it, rather than strike something else. It is part of a lightning protection system. Such a system is made of many such rods. These rods are usually placed at high points of buildings and structures.
Saturday, September 16th, at But when it comes to Police Chief Gorden Eden, they are singing from the same page. Not long after the new mayor takes office Dec. And that typically comes down to the chief. Eden, a former U. Marshal and secretary of the state Department of Public Safety, was appointed by Berry in after the departure of Ray Schultz and interim chief Allen Banks. He has been dogged by some of the same issues that his predecessors struggled with — high crime rates, not enough officers and a rocky relationship with the police union.
Stover to Eden, has faced the same issues. By the time the next police academy graduates next year, the department may have the same number of officers it had in the mid s under then-Chief Joe Polisar — At that time, the city ranked number one in the nation for felony crimes reported per , population. Last year, the city ranked in the top 10 in the nation for property crime and was in the top 50 for violent crimes. The chief is on the hot seat no matter who started the fight. The independent counsel position and old Police Advisory Board have been replaced twice by civilian boards that have had varying degrees of success in dealing with past chiefs.

The news just announced a three story house struck by lightning. Well, duuuuh, high scoll teachers tell students a tall house can be struck, so why doesn’t the building code cover this hazard. It’s a lot cheaper to instal lightning rods than to have part or all the house damaged.
This system is designed to control the time and the location of a lightning strike. The lightning rocket can be comprised of solid propellant that has cesium salts added which produces a conductive path when the exhaust gases are discharged from the rocket that is expelled to the static layer of a thundercloud. A conducting lightning rod which is grounded and positioned along side the launch tube for the solid propellant is in communication with the conductive path to thereby control the time and location of a lightning strike from the thundercloud.
In a liquid expelled rocket a solution of calcium chloride is used to form a conductive path from a thundercloud. As the rocket flies to the thundercloud this liquid is expelled aft forming a column in the air of particles that are more electrically conductive than the surrounding air. In a similar fashion to the system employing a solid propellant as the conductive producer this conductive path conducts a lightning strike to ground to thereby control the time and location of a lightning strike from the thundercloud.

See Article History Alternative Title: Because lightning tends to strike the highest object in the vicinity, rods are typically placed at the apex of a structure and along its ridges; they are connected to the ground by low- impedance cables. In the case of a building, the soil is used as the ground ; on a ship , the water is used. A lightning rod and its associated grounding conductors provide protection because they divert the current from nonconducting parts of the structure, allowing it to follow the path of least resistance and pass harmlessly through the rod and its cables.

The European Table Abacus Circa The European table abacus or reckoning table became standardized to some extent by this time. The pebbles previously used as counters were replaced by specially minted coin-like objects that were cast, thrown, or pushed on the abacus table. They were called jetons from jeter to throw in France, and werpgeld for “thrown money” in Holland. In the wood block shown on the left a wood block from Margarita Philosophica, by Gregor Reisch , shows a table abacus.
This 50 digit abacus is approximately 30cm The notation is bi-quinary: The beads are moved to add or subtract, and when all beads in a deck are up a carry to the next position is made. Multiplication and division are carried py repetetive addition and subtraction. It usually has more than seven rods. There are two beads on each rod in the upper deck and five beads each in the bottom for both decimal and hexadecimal computation. The beads are usually rounded and made of a hardwood. The beads are counted by moving them up or down towards the beam.
If you move them toward the beam, you count their value. If you move away, you don’t count their value.

It cannot be more explicit. This vast monument of uncertain origin was among the first lightning traps , a sacred architectural complex where the novices were given awakening by fire from heaven. Teotihuacan was once, and during a long time, the largest city in Mexico, and the capital of the largest pre-Columbian empire. Two main avenues running north-south and east-west divided the city into quarters. The ancient city was built according to a specific grid, and stretched over 8 square miles.
When was this beautiful architectural set built?
Lightning is an age-old problem with protection solutions dating back to when Dr. Benjamin Franklin experimented with lightning protection and discovered that a sharp point dissipates charge. This discovery led to the grounding rod which is still in use today.
History[ change change source ] Lightning can damage structures made of most materials masonry, wood, concrete and even steel. The huge currents involved can heat materials, and especially water to high temperatures. This will cause fire, loss of strength and explosions from superheated steam and air. Europe[ change change source ] Wooden church with lightning rods and grounding cables The church tower was usually the highest structure or building in medieval European towns and villages.
It was also the building very often hit by lightning. Early on, Christian churches tried to prevent the damage of lightning by prayers. Priests prayed, “temper the destruction of hail and cyclones and the force of tempests and lightning; check hostile thunders and great winds; and cast down the spirits of storms and the powers of the air. The structure was fastened by three metal chains, conductively attached to the iron grounding cones buried in the packed down soil.
He described his ‘weather machine’ in the treatise ‘Descriptio machinae meteorologicae’. The original idea was to continually sap the electricity out of the clouds and so actually prevent the lightning and the storms, only in case this failed, the machine should have also been able to directly attract the lighting and channel it to the ground.
He proposed his machine to be used on church towers and ships. The emperor let the mathematicians in Vienna judge the proposal, but they refused it.

Lightning arrester In telegraphy and telephony , a lightning arrester is a device placed where wires enter a structure, in order to prevent damage to electronic instruments within and ensuring the safety of individuals near the structures. Lightning arresters, also called surge protectors , are devices that are connected between each electrical conductor in a power or communications system, and the ground.
They help prevent the flow of the normal power or signal currents to ground, but provide a path over which high-voltage lightning current flows, bypassing the connected equipment. Arresters are used to limit the rise in voltage when a communications or power line is struck by lightning or is near to a lightning strike. Protection of electric distribution systems[ edit ] In overhead electric transmission high-tension systems, one or two lighter gauge conductors may be mounted to the top of the pylons, poles, or towers not specifically used to send electricity through the grid.
These conductors, often referred to “static”, “pilot” or “shield” wires are designed to be the point of lightning termination instead of the high-voltage lines themselves. These conductors are intended to protect the primary power conductors from lightning strikes.
The Smith Cemetery Prairie is lush with prairie plants in summer months. A visit in the early s left me wanting to return, so off I went across the Wabash River with my friend Joanna, our cameras and time for adventures. By , mowing had stopped and the property began to be managed as a prairie. Controlled fires now keep the prairie in its natural condition.
Dedicated as a state nature preserve in , over 30 species of prairie plants grow on the property. Summer heat means color on the prairie, and this day was no exception.
