A very early example of a ray gun is the Heat-Ray featured in H. G. Wells ' The War of the Worlds ( 1898 ).

The tripods are armed with a Heat-Ray, which is fired by a camera-like mechanism held by an articulated arm and Black Smoke, a type of poison gas which is deployed by cylinders, not unlike a soldier's bazooka.

Designed by Albert Nozaki, this machine is armed with a reddish and visible Heat-Ray — once more in keeping with the novel — mounted atop in a gooseneck device incinerating anything the ray hits.

These weapons are immediately hypothesized authoritatively by the character Dr. Clayton Forrester to neutralize mesons, " The atomic glue holding matter together ," causing the target to vaporize, usually leaving behind a black stain on the ground ( either the burned remains or a scorching of the terrain ), and appear to be deployed as a long range surface weapon as compared to the Heat-Ray which is used at closer range and against taller structures or aircraft.

Aside from the legs, there is no visible mounted Heat-Ray ; however, where the latter models have a green window in its front, the tripods have an orange / red colored window ( framed in blue circle ) that, coupled with its pulsating glow, suggests that it is a cruder version of their Heat-Ray and is built into the body of the machine.

Whether it is a Heat-Ray, or what other weaponry this model possesses is unknown.

The Heat-Ray is built into the body of the machine, shooting through a slot on its " head ", which can turn around on the bottom part that houses the legs.

This version of the tripods does have some inconsistencies from Wells's description in his novel ; for example, the Heat-Ray emanates from a proboscis in the cupola rather than from a box or case carried by the tripod, the cage to hold captured humans being is used by the handling-machines instead of the fighting-machines, and the " cowl " ( cockpit ) of the fighting-machine is static instead of separately rotating.

The Heat-Ray is the primary offensive weapon used by the Martians in H. G. Wells ' classic science fiction novel The War of the Worlds and its offshoots.

Within the context of the novel, the term " Heat-Ray " is more commonly applied to the destructive energy it projects and not the weapon itself.

The weapon that fires the Heat-Ray is described as a box-like or camera-like case that generates the Heat-Ray.

The Heat-Ray is essentially a directed-energy weapon that incinerates anything it comes into contact with.

The only visible element of the ray was a flash emitted from the chamber while the Heat-Ray is fired.

The Heat-Ray is one of the most common features of virtually every adaptation of the story.

In Sherlock Holmes's War of the Worlds, the Heat-Ray is described as being based on nuclear energy, with it being projected from a pink-hued, multifaceted focusing crystal.

The machines walk upon legs ( four legs instead of three ) and carry a weapon above their head on a neck, resembling the Martian Heat-Ray from the 1953 film adaptation of War of the Worlds.

The Great Illustrated Classics adaptation of The War of the Worlds portrays the Heat-Ray as a massive flamethrower.

In Steven Spielberg's War of the Worlds adaptation of Wells ' novel, the Heat-Ray is portrayed as two bluish-white rays that appear to have a desiccating effect on living objects, such as animals, and a ' disruptive ' effect on other objects.

A fleet of jets, upgraded with the Martian technology left from the first film, are equipped with a kind of Heat-Ray and missiles containing mustard gas, a weapon that has only been used in warfare once before, in World War I.

They are depicted with details of the tripods from Wells ' original novel ; they have the Heat-Ray and baskets for captured humans.

The Heat-Ray appears on the top of tripod head as a round mirror on a metallic arm, and when the mirror rotates at fast speed it begins to emit incredible heat with a range of over 2 miles.

For the 1953 film version, the Martians use a combination of three rays, one Heat-Ray on top of their machines which fire red sparks, and two disintegrator rays at the side, which are shown as green energy bolts.

Both types of the Heat-Ray have a less violent effect on its target as most of what they would hit would begin to glow and then vanish, sometimes leaving a stain or pile of ash as a remainder ; the Heat-Ray differs from the disintegrators ( also called " skeleton beam ") as the former sets the surrounding environment ablaze as well as vaporizing the target within a few seconds.

Although, often, the Heat-Ray does have a simple destructive effect on certain objects ; other times, the ray would set objects ablaze or cause them to explode ( as shown when the machines reach Los Angeles ).

The novel states that since her guns remained quiet as she charged the tripods, she was probably not immediately seen as a threat, so she was not immediately destroyed by their Heat-Ray.

It crashes into a fighting-machine after being critically damaged by its Heat-Ray.

A tall rod with a spinning circular disk at the top was seen, followed by three puffs of green smoke, then a dome-like object would pop out and fire the Heat-Ray ( seen as a flash of light ).

The Heat-Ray emanates from a proboscis in the cupola rather than shooting from a box or case carried by the tripod.

In Edison's Conquest of Mars, as an answer to the Heat-Ray, Thomas Edison designs a disintegrator ray for use by human forces.

In one scene, the President of the United States, played by Leslie Nielsen, announces to the United Nations that America has managed to capture a Heat-Ray.

However, a bridge in one scene is thrown from its pylons when hit by the ray, as if physically struck, and in an earlier scene, brick-and-wood buildings are either destroyed or catch fire when hit by the Heat-Ray.

After seeing the ship's continued advance, the Martians deployed their Heat-Ray, inflicting a great amount of damage upon Thunder Child.

Although she appeared to score no significant hits and one of her misses sunk a nearby fishing smack, she was able to set a collision course with the second Martian tripod before its Heat-Ray found her.

Similar to the book, the tripods appear to emit some kind of black-green smoke before arming and firing the Heat-Ray, although this may only be dust and steam from clearing the vents.

In Scary Movie 4, a spoof of Spielberg's film, the Tripods have only three tentacles, and fire the Heat-Ray from their centre eye.

His name is Praisegod Piepsam, and he is rather fully described as to his clothing and physiognomy in a way which relates him to a sinister type in the author's repertory -- he is a forerunner of those enigmatic strangers in `` Death In Venice '', for example, who represent some combination of cadaver, exotic, and psychopomp.

The reality of the situation, however, is described by Mr. Lyford: ``

Much of his earlier work was conceived in terms of a `` pseudo-anthropological '' myth reference, which is concerned with imaginary places and beings described in grandiloquent and travelogue-like language.

The first part of the new structure -- that for supporting the basic program of vocational rehabilitation services -- is described in this Section.

This two-part bridge is best described by Rev. Timothy Dwight, president of Yale College, in his `` Travels In New-England And New-York '', published in New Haven in 1821.

The experimental arrangement as described below is based on the geometry of free burning arcs.

The case described in this paper is that of an older man who developed disabling muscular weakness while receiving a variety of steroids for a refractory anemia.

The theorem which we prove is more general than what we have described, since it works with the primary decomposition of the minimal polynomial, whether or not the primes which enter are all of first degree.

We now shall show that any involution with these characteristics is necessarily of the type we have just described.

How this was accomplished may be described, since this sometimes is a crucial problem.

A second explanation is suggested by the material described in Rowlands' paper.

If a litigant chooses to enforce a Federal right in a State court, he cannot be heard to object if he is treated exactly as are plaintiffs who press like claims arising under State law with regard to the form in which the claim must be stated -- the particularity, for instance, with which a cause of action must be described.

First, it appears to be based on the fact that on its title page Utopia is described as `` festivus '', `` gay ''.

It overlooks the other fact that it is described as `` Nec minus salutaris quam festivus '', `` no less salutary than gay ''.

What is missing is work that would answer, presumably by the use of survey methods and Guttman-type attitude scales, such questions as these: What are the components of the feeling-state described as alienation??

They echo the words with which he has described his own vision of the dying child who `` trembles and begs for mercy -- and there is no mercy ''.
