sacrifice effort demand
Every effort under compulsion demands a sacrifice of energy. I never paid such a price.
past goal effort
Universal peace as a result of cumulative effort through centuries past might come into existence quickly - not unlike a crystal that suddenly forms in a solution which has been slowly prepared. Science is but a perversion of itself unless it has as its ultimate goal the betterment of humanity.
loss views effort
We build but to tear down. Most of our work and resource is squandered. Our onward march is marked by devastation. Everywhere there is an appalling loss of time, effort and life. A cheerless view, but true.
mother men effort
My mother understood human nature better and never chided. She knew that a man cannot be saved from his own foolishness or vice by someone else's efforts or protests, but only by the use of his own will.
ignorance evil effort
Of all the frictional resistances, the one that most retards human movement is ignorance, what Buddha called 'the greatest evil in the world.' The friction which results from ignorance ... can be reduced only by the spread of knowledge and the unification of the heterogeneous elements of humanity. No effort could be better spent.
effort brain fiber
But instinct is something which transcends knowledge. We have, undoubtedly, certain finer fibers that enable us to perceive truths when logical deduction, or any other willful effort of the brain, is futile.
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.
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.

There is no memory or retentive faculty based on lasting impression. What we designate as memory is but increased responsiveness to repeated stimuli.
