actual certainly change completed conceived developed devices drawn electric engine exactly imagination inventions machine mind operate parts run single sketch test thirty though vacuum whether wireless worked
Before I put a sketch on paper, the whole idea is worked out mentally. In my mind I change the construction, make improvements, and even operate the device. Without ever having drawn a sketch I can give the measurements of all parts to workmen, and when completed all these parts will fit, just as certainly as though I had made the actual drawings. It is immaterial to me whether I run my machine in my mind or test it in my shop. The inventions I have conceived in this way have always worked. In thirty years there has not been a single exception. My first electric motor, the vacuum wireless light, my turbine engine and many other devices have all been developed in exactly this way.
branches currents ebb electric motion nature seems
As in nature, all is ebb and tide, all is wave motion, so it seems that in all branches of industry, alternating currents - electric wave motion - will have the sway.
added appliances electrical knowledge nature provided revealed science thereby true vastly
Electrical science has revealed to us the true nature of light, has provided us with innumerable appliances and instruments of precision, and has thereby vastly added to the exactness of our knowledge.
electric-power oil needs
Electric power is everywhere present in unlimited quantities and can drive the world's machinery without the need of coal, oil, gas, or any other of the common fuels.
electric-current brightness lamps
I predict that very shortly the old-fashioned incandescent lamp, having a filament heated to brightness by the passage of electric current through it, will entirely disappear.
air colorado conditions extremely favorable gratifying laboratory mountains proved pure results
I constructed a laboratory in the neighborhood of Pike's Peak. The conditions in the pure air of the Colorado Mountains proved extremely favorable for my experiments, and the results were most gratifying to me.
afford brush currents effects high operated pleasing vary
When a coil is operated with currents of very high frequency, beautiful brush effects may be produced, even if the coil be of comparatively small dimensions. The experimenter may vary them in many ways, and, if it were nothing else, they afford a pleasing sight.
complete existing forces intimate led nature phenomena relation science thus widely
Electrical science has disclosed to us the more intimate relation existing between widely different forces and phenomena and has thus led us to a more complete comprehension of Nature and its many manifestations to our senses.
air bounty developed drawn earth fourteen german later nitrogen process purpose stress war
The earth is bountiful, and where her bounty fails, nitrogen drawn from the air will refertilize her womb. I developed a process for this purpose in 1900. It was perfected fourteen years later under the stress of war by German chemists.
branches perhaps promising various
Of the various branches of electrical investigation, perhaps the most interesting and immediately the most promising is that dealing with alternating currents.

The Secretary of Hygiene or Physical Culture will be far more important in the cabinet of the President of the United States who holds office in the year 2035 than the Secretary of War.
based faculty increased repeated
There is no memory or retentive faculty based on lasting impression. What we designate as memory is but increased responsiveness to repeated stimuli.
economical harness known method
The harness of waterfalls is the most economical method known for drawing energy from the sun.
I myself eschew all stimulants. I also practically abstain from meat.
