Generally the author has to savagely pound a square peg into a round hole, with regrettable results. The classic horrible example is deep space fighter aircraft. Most pulp falls for the old Space Is An Ocean fallacy along with the related misconceptions. Many pulp writers figured they were the first to have the bright idea of transplating the colorful legend of the dreaded Sargasso Sea into science fiction.

A deadly area of space that somehow traps spaceships who venture too close, only to join the deadly graveyard of lost ships. And not just human ships, a couple stories mention humans discovering wrecks of unknown alien spacecraft mixed in with the conventional ships.

The graveyard typically contains everything from recent ships all the way back to historical ships dating to the dawn of space flight. Some stories populate the graveyard of dead ships with castaways. Who will probably be interested in looting your ship of any supplies it contains.

The original legend dates back to when line-of-sight was limited to the horizon, so a sailing vessel poking at the edge of the sargasso could not see the interior. Not without being caught, that is. With the invention of radar and the realization that there ain't no horizon in space, writers realized they'd have to make the space sargasso sea more invisible.

Usually they'd add on the legend of the Bermuda Triangle in the form of an intermittent "hole in space" leading to a pocket universe. Some kind of wormhole or stargate that would transport the hapless spacecraft to a graveyard of lost ships safely out of sight.

Obviously this is highly unlikely to happen in the real world. But it sure is romantic, in a sci-fi pulp fiction sort of way. Disabled spacecraft who drift into the point will be trapped, which is sort of true. The author does not explain why this is not true of the L4 and L5 points of every single planet in the solar system.

He calls the graveyard of lost ships the "wreck-pack", and the gravitational attraction of the wrecks keep ships from drifting out. The latter is a concept that was disproved by Michelson and Morley inbut most of the readers didn't know that.

The ether-currents form sort of a one-way whirlpool which sucks hapless spacecraft into the graveyard of lost ships trapped in the eye of the storm.

Captain Future escapes by cannibalizing engine and atomic fuel from the other derelict ships, an idea that apparently didn't occur to any of the prior castaways. He has a side adventure when he stumbles over an alien spacecraft full of aliens in suspended animation.

The "adventure" part comes in when Captain Future discovers the octopoid creatures are space vampires and they start to wake up.

Certainly strange things happen to hyperdrive starships who venture too close. Things like hallucinations, ghostly whispering voices "Spaceman, go home.

Many dissappear, so prudent ship captains give the Nebula a wide berth. The cause of all this is an ancient race of Elf-like psionic aliens living on a planet near the Nebula's center.

The antigravity Okie cities are sort of the migrant laborers of the galaxy. The stellar currency is based on germanium, some idiot figure out how to synthesize it and inadvertenly obliterated the economy of the entire galaxy.Essay on Electormagnetic Spectrum.

What is the electromagnetic spectrum? The electromagnetic spectrum is a range of wavelength frequencies over which electromagnetic radiation extends.

There are five different types of electromagnetic waves: Radio waves, microwaves, gamma rays, ultraviolet, and X- rays.

Electromagnetic Waves - Essay

The electromagnetic spectrum is a continuum of all electromagnetic waves arranged according to frequency and wavelength. The electromagnetic spectrum extends from low frequencies used for modern radio to gamma radiation at the short-wavelength end, covering wavelengths from thousands of kilometres down to a fraction of the size of an .

- Electromagnetic Waves essay Radiation is the emission of energy as electromagnetic waves or as moving subatomic particles; an example of radiation is, electromagnetic lausannecongress2018.com is a form of radiant energy which travels through space via electromagnetic waves.

- The Electro Magnetic Spectrum Radio Waves Radio waves . This study originally arose out of an e-mail discussion with Rafael Capurro at the artefactphil discussion group in I am therefore indebted to him for important impulses.

Cf. Rafael Capurro's analogous article Beitr├Ąge zu einer digitalen Ontologie (Contribution to a Digital Ontology), from which the present study deviates considerably in both content and scope of presentation. Electromagnetic waves can be described as a wave that consists of oscillating electric and magnetic fields, which radiate outward from the source at the speed of light.

The electromagnetic spectrum consists of radio waves, microwaves, infrared waves, visible light, ultraviolet light, X-rays, and gamma rays/5(1). The electromagnetic spectrum is made up of six different types of waves.

Radio waves, Microwaves, Infrared waves, Visible light, Ultraviolet light, X-rays and Gamma rays. The radio waves are used to transmit radio and television signals.
