By a series of discoveries and inventions just perfected, Nikola Tesla, the electrical scientist, has upset what has hitherto been regarded as one of the fixed laws of nature. “Every effect diminishes with distance,” is the way the textbooks have expressed it. Tesla now says that instead of decreasing like other forces, electricity may be made to increase in intensity with the distance traveled.
The full significance of this discovery may not be at once apparent. It is obvious, however, that it annihilates space. There can be no limit to the power of the electric wave which increases in intensity the further it travels.
For nearly 20 years Tesla has been working on his plan, he calls it his wireless “World System.” If it is put into successful execution it will convert the earth into a gigantic conduit, which will pass power for all earthly activities, and make possible communication with other planets.
From time to time Tesla has made partial announcements as his work progressed. This, however, is the first comprehensive account of his system as a whole that the inventor has consented to give to the world.
“Through ages past man has anyways attempted to project in some way or other energy into space. In all his attempts, no matter what agent he employed, he was hampered by the inexorable law of nature which says every effect diminishes with distance, generally as the square of the same, sometimes more rapidly.
“I saw at once that space was annihilated in all the three aspects; in the transport of our bodies and materials and in the earth, transmission of the energies necessary for our existence. You can imagine how profoundly I was affected by this revelation. Technically, it meant that the earth, as a whole, had certain periods of vibrations, and that by by impressing electrical vibrations of the same periods upon it, it could be thrown into oscillations of such nature that innumerable benefits could be derived.
“It is difficult to convey an idea of these inventions without resorting to technical terms. The first and best known of these is my transformer, which enables the production of electrical vibrations of transcending intensities. I have already attained activities of many millions of horse power; but this is nothing compared to those which I am expecting to get with my improved apparatus.
“The second is what I have termed my magnifying transmitter, which I look upon as my best electrical invention, and with which any distance can be bridged. I have already passed of this wonderful instrument and am confident that a message can be flashed to such a distance as the planet Mars.
“Some technical men would be disposed to look upon such statements as those of a dreamer, but it is only because they have not had opportunities to see experiments which I have actually performed. The third invention I have designated as the “Art of individualization,” which enables the transmission of an unlimited number of messages through a wire or wireless, without the slightest interference. Not before this improvement is universally adopted will the world fully realise the benefits of telegraphy and telephony. The fourth invention is my receiver, which concentrates the energy transmitted over a wide area into the operating device.”
What would the voltage in your transmitter be?
“In the transmission of telegraphic and telephonic messages I shall employ from five to ten million volts, but in transmitting power in great quantities, as much as one hundred million volts will be used.“
How will your “World System” compare with those now in use as regards to cost?
“We could easily afford to offer a transmission of telegraphic and telephonic messages to any terrestrial distance for five cents a word. In a short while no one will think it anything out of the way to dictate or to write a long letter across the Pacific.”
How long does it take for the transmission of a message, by your system, around the world?
“The exact time is, according to my measurements, 43-1000 of a second, which is a speed about 50 per cent greater than that of light.
“The impulse starts from my magnifying transmitter with infinite speed, slows first rapidly and then at a lesser rate until, when it has penetrated to a distance of 6000 miles from the transmitter, it proceeds with approximately the speed of light. From there on it accelerates, first slowly and then more rapidly, and reaches the opposite point of the globe again with infinite speed only to rebound and pass through the same phases on its way back to the transmitter.
“This movement of electricity through the Earth, which takes place strictly in accordance with a mathematical law, and enables a great number of accurate measurements and determinations to be made, which are of immense practical and scientific value.”
Is your universal marine service based upon this principle?
“Largely so. In setting up and maintaining stationary waves in the earth its entire surface is subdivided in perfectly definite zones of electric activity, so that any observer of all those data which are of importance to navigators as the latitude and longitude, the position with reference to a given point, the speed of travel, and the course followed. This method is quite exact and reliable, and once introduced will be instrumental in a great saving of time, life and property.”
When your system of time distribution is introduced what kind of devices will be used for indicating the hour?
“They will be ever so much simpler than the ordinary clocks or watches, being entirely devoid of wheel work. For personal use a small case will be provided resembling that of a watch which would indicate precisely the time and require no more attention than a compass for instance. The large clocks on towers and public edifices in general will be replaced by extremely simple devices operated on the same principle.
“All these will be ‘tuned’ to a wireless wave sent out at a certain time. This will automatically set the hands of every ‘tuned’ time piece.”
In operating stock tickers, will the present instruments have to be replaced by others?
“Not at all, they will remain intact. A great financier told me that this should be one of the most valuable and practical applications of my system, inasmuch as the instantaneous operation of such instruments all the world over will go far toward allaying panics and failures which are at present mostly due to the inadequacy and stagnation of channels of information.”
“A business man will be able to dictate in his office a letter which will appear in type at any other place he wishes without loss of time in the transmission. It will be exactly as though he had his stenographer close by. In the same manner it will be practicable to send a handwritten letter or even a check, and what is more important, it will not be possible to falsify the signature.”
Will the transmission of complex musical productions require complicated apparatuses?
Not at all. The apparatus at any of the master plants, transmitting a great number of musical compositions, will be of necessity complicated, but the subscriber will need only a telephone receiver, and, if he desires exclusiveness, and individualizing device in connection, which, however, will be rarely required. He will be none the less able to listen to the most complex opera played in some remote party of the world. What is more, he can carry the entire outfit with him on his walks and travels, and whenever he desires to listen to the music he can do so.
The wireless system which I have developed does not contemplate competition with established lighting systems in densely populated districts, but it offers an ideal solution for the illumination of isolated places. The light will be furnished by exhausted glass tubes, bent in all sorts of ornamental shapes, and is of surpassing beauty, resembling closely the daylight. The lamps will last forever. The entire apparatus for lighting the average country dwelling will contain no moving part whatever, and could be readily carried about in a small valise. It will be quite immaterial in which region of the earth the house to be lighted is located. Distance will not affect the charge.“
How far from the Earth’s surface can power be transmitted by this wireless system?
“To any distance; in fact, the greater the elevation above the ground that easier it is to supply the power to the vehicle, such as an airship crossing the ocean.”
What do you consider the most important application of your system?
The transmission of power, of course. The operation of aerial machines alone will be of a revolutionizing influence, in as much as it will afford a perfect solution of this important problem. Another great field will be the irrigation and fertilization of the soil by wireless power. The time is not distance when a farmer will have installed on his place an apparatus for continuously manufacturing, from the gases of the atmosphere, nitric compounds which will be used to fertilize, while a motor will pump the water and perform other duties; all the energy being supplied from a plant perhaps thousands of miles away. This system can be extended so as to make productive vast tracts of now barren lands located in various countries. I believe that the export of wireless power will be one of the chief resources of the United States and other fortunately situated countries in times to come.“

An accessible approach to making a mini-brain
If you need a working miniature brain — say for drug testing, to test neural tissue transplants, or to experiment with how stem cells work — a new paper describes how to build one with what the Brown University authors say is relative ease and low expense. The little balls of brain aren’t performing any cogitation, but they produce electrical signals and form their own neural connections — synapses — making them readily producible testbeds for neuroscience research, the authors said.
“We think of this as a way to have a better in vitro [lab] model that can maybe reduce animal use,” said graduate student Molly Boutin, co-lead author of the new paper in the journal Tissue Engineering: Part C. “A lot of the work that’s done right now is in two-dimensional culture, but this is an alternative that is much more relevant to the in vivo [living] scenario.”
Just a small sample of living tissue from a single rodent can make thousands of mini-brains, the researchers said. The recipe involves isolating and concentrating the desired cells with some centrifuge steps and using that refined sample to seed the cell culture in medium in an agarose spherical mold.
The mini-brains, about a third of a millimeter in diameter, are not the first or the most sophisticated working cell cultures of a central nervous system, the researchers acknowledged, but they require fewer steps to make and they use more readily available materials.
“The materials are easy to get and the mini-brains are simple to make,” said co-lead author Yu-Ting Dingle, who earned her Ph.D. at Brown in May 2015. She compared them to retail 3-D printers which have proliferated in recent years, bringing that once-rare technology to more of a mass market. “We could allow all kinds of labs to do this research.”
The spheres of brain tissue begin to form within a day after the cultures are seeded and have formed complex 3-D neural networks within two to three weeks, the paper shows.
25-cent mini-brains
There are fixed costs, of course, but an approximate cost for each new mini-brain is on the order of $0.25, said study senior author Diane Hoffman-Kim, associate professor of molecular pharmacology, physiology and biotechnology and associate professor of engineering at Brown.
“We knew it was a relatively high-throughput system, but even we were surprised at the low cost per mini-brain when we computed it,” Hoffman-Kim said.
Hoffman-Kim’s lab collaborated with fellow biologists and bioengineers at Brown — faculty colleagues Julie Kauer, Jeffrey Morgan, and Eric Darling are all co-authors — to build the mini-brains. She wanted to develop a testbed for her lab’s basic biomedical research. She was interested, for example, in developing a model to test aspects of neural cell transplantation, as has been proposed to treat Parkinson’s disease. Boutin was interested in building working 3-D cell cultures to study how adult neural stem cells develop.
Morgan’s Providence startup company, MicroTissues Inc., makes the 3-D tissue engineering molds used in the study.
The method they developed yields mini-brains with several important properties:
Diverse cell types: The cultures contain both inhibitory and excitatory neurons and several varieties of essential neural support cells called glia.
Electrically active: the neurons fire and spike and form synaptic connections, producing complex networks.
3-D: Cells connect and communicate within a realistic geometry, rather than merely across a flat plane as in a 2-D culture.
Natural density: Experiments showed that the mini-brains have a density of a few hundred thousand cells per cubic millimeter, which is similar to a natural rodent brain.
Physical structure: Cells in the mini-brain produce their own extracellular matrix, producing a tissue with the same mechanical properties (squishiness) as natural tissue. The cultures also don’t rely on foreign materials such as scaffolds of collagen.
Longevity: In testing, cultured tissues live for at least a month.
Hoffman-Kim, who is affiliated with the Brown Institute for Brain Science and the Center for Biomedical Engineering, said she hopes the mini-brains might proliferate to many different labs, including those of researchers who have questions about neural tissue but not necessarily the degree of neuroscience and cell culture equipment required of other methods.
“If you are that person in that lab, we think you shouldn’t have to equip yourself with a microelectronics facility, and you shouldn’t have to do embryonic dissections in order to generate an in vitro model of the brain,” Hoffman-Kim said.

Centaurus A or NGC 5128 is a galaxy in the constellation of Centaurus.
The center of the galaxy contains a supermassive black hole with a mass equivalent to 55 million solar masses, which ejects a relativistic jet that is responsible for emissions in the X-ray and radio wavelengths. By taking radio observations of the jet separated by a decade, astronomers have determined that the inner parts of the jet are moving at about half of the speed of light. X-rays are produced farther out as the jet collides with surrounding gases resulting in the creation of highly energetic particles. The X-ray jets of Centaurus A are thousands of light-years long, while the radio jets are over a million light-years long
