current rotation

Nikola Tesla was an inventor, discoverer, electrical engineer, mechanical engineer, theoretical and experimental physicist, mathematician, futurist and humanitarian. He is responsible for over ninety percent of the transmission of electrical power the world relies on today thanks to his discovery of the rotating magnetic field. The inventor utilized this discovery in his invention and patent of the first commutatorless alternating current induction motor which changed the future of power transmission. All electrical technology using or generating alternating current today is due to Tesla, without which all our trolley cars, electric vehicles, subways, manufacturing/industrial plants and electrified power lines, which bring power to almost every single electrical appliance/equipment in our homes/work, would be impossible.

Tesla was a Serbian born on July 10, 1856 at midnight in Smiljan, Lika (in what is now Croatia). He was educated at an early age by his parents before attending the Gymnasium Karlovac in Croatia, the Polytechnic Institute in Graz, Austria; and the University of Prague excelling in linguistics, mathematics and sciences. He was a hyper-polyglot who could speak eight languages including: Serbo-Croatian, English, Czech, French, German, Hungarian, Italian, and Latin. He claimed to have had a three-dimensional memory and thought process that tormented him in his youth, but later aided him with building his inventions in his own mind without wasting any physical energy. He was known to be able to recite by heart full books, mathematical formulas and poetry such as Goethe’s “Faust,” Njegoš’ “The Mountain Wreath,” Dante’s “Divine Comedy,” Shakespeare’s “Hamlet,” Byron’s “Childe Harold’s Pilgrimage,” and Pushkin’s “Eugene Onegin.”

In 1881 while walking with a friend in a City Park reciting Goethe’s “Faust,” Tesla first envisioned the rotating magnetic field and his induction motor– complete, perfect, and operable in form. This visualization would represent the same diagrams shown in a lecture given before the American Institute of Electrical Engineers in 1888.

After his revelation, in 1882, Tesla’s began working for a telephone company in Europe, while he worked independently on his induction motor. In 1884, he moved to America in hopes of capitalizing on his new discovery. Initially, Tesla was hired by Thomas Edison, but the famous American inventor was not interested in Tesla’s alternating current system, due to his already strong interest in direct current power transmission. Tesla would continue working for Edison until Edison promised him $50,000 to make improvements on his DC generation plants. After completing the task, Tesla asked to be paid, but Edison denied him his offer and explained that the offer of $50,000 was just an “American joke.” Edison offered Tesla a small raise, but Tesla resigned instead.

After his fallout with Edison, Tesla was offered his own lighting company by some small investors, but unfortunately, they were also not interested in Tesla’s alternating current system. Tesla would invent a new and efficient arc lamp for the company, but would be forced out of the business after completing his work. This was a bitter blow to the young Serbian who resorted to digging ditches for $2 an hour in order to get by in a new country.

Tesla’s luck would soon change in 1887, after he received a chance to demonstrate his system of alternating currents to some financiers with his famous “Egg of Columbus” demonstration. This great event would lead to the filing of his Alternating Current Poly-phase Induction Motor patent. This opened a wide door for the introduction and commercial development of alternating current motors.

Tesla pushed forward building apparatuses equal in productivity to DC motors, forcing the scientific community to recognize his work. Because of this work, in May of 1888, a publication of Tesla’s work was read before the American Institutes of Electrical Engineers. Prior to Tesla’s invention, it was considered impossible to eliminate the brushes and commutators on the old motors, but the introduction of Tesla’s new electrical theory and practice was an obvious departure from the old into the new. It was completely revolutionary yet so simple. The introduction of his new patent would spark a strong interest in American entrepreneur, George Westinghouse, who would later buy Tesla’s patents, and throw all his resources into the development of Tesla’s work. This new industry in power transmission would eventually start a feud between the Westinghouse Company and Thomas Edison’s General Electric Company–known as the “War of Currents" (AC/DC)…

Wireless charging of moving electric vehicles overcomes major hurdle

If electric cars could recharge while driving down a highway, it would virtually eliminate concerns about their range and lower their cost, perhaps making electricity the standard fuel for vehicles.

Now Stanford University scientists have overcome a major hurdle to such a future by wirelessly transmitting electricity to a nearby moving object. Their results are published in the June 15 edition of Nature.

nitrosparxx  asked:

Hello. I had a question and I was hoping to gain a new perspective on something. I'm a musician, about to graduate as a music tech student. I've made music since 2009 and i'm starting to doubt if I'm being creative enough or even if my work is of value or is worth existing. Sorry I rambled there. Basically my question is; what does it mean (in your opinion) to be creative? What does it mean to make something of value? How does it have value? I just feel lost at the moment...

Something that has value in art says something about existence, the human condition, and facets of life. I think one of the absolute smartest things I’ve ever read, anywhere, about any form of art, can be found in a quote on writing I once read. I’ll need to paraphrase, because I can’t find the source online, but it’s stuck in my brain for years, and that’s the real testament to its power:

“A writer does not write to make readers understand his pain, he writes to make the reader know he understands theirs.”

That’s when art is at its most powerful–when it shows you something that hits your empathy center so strongly, it brings you to fierce emotion. Maybe it makes you walk away from what you were watching to text your mother and let her know you love her, or it scares you deeply enough to turn on a light and double-check to be sure the doors are locked.

At its best, art captures an experience you’ve been through (or are going through) that you didn’t understand anyone else shared, or reveals something that speaks a truth you never quite noticed using a communication style that isn’t straight-up talking. Art is someone who knows exactly what you’ve been thinking or feeling. It can show you that you’re not alone and also relate the experience or truth of someone or something else in the world you didn’t previously relate to.

Art is a statement on what you have learned and felt in this world, either through site and study or personal experience, and its knowledge exists in an expressive way that really connects to the empathy or intellectual understanding of a person.

I’ll give you an awesome example right now of music and art and the differences between the two for this precise moment in time:

Ed Sheeran used to be a really folksy, “hipster coffee shop” musician. That’s where he started, that’s what he was known for. The current song in rotation from him is the same stupid “meet hot girl at bar, take her home, have great sex, sing about it in a way I’ll get more sex from more hot girls at bars” bullshit that we hear every month from multiple artists.

https://www.youtube.com/watch?v=JGwWNGJdvx8

(Of course, he disguises it with a nice video, but that’s a pretty common technique now.)

Katy Perry, who used to be a peddler of so much of the type of music I just described above, has released a new song with lyrics criticizing this exact culture, recognizing how badly she played a role in it, she’s definitely partly at fault, and society as a whole has failed when it comes to celebrating media that actually says something, because pumping out vain, fun, sexy garbage keeps us “safe.”

https://www.youtube.com/watch?v=Um7pMggPnug

Ed Sheeran’s new song is not art to me. Katy Perry’s new song is.

Go figure. But, you know, this is a time in history when literally the most impossible things are happening every month, so expect the unexpected.

Make songs that share insight, experience, lessons, and what you see and understand. Art is within you.

How much faster would time pass for us if the earth was motionless and as such we were as well at least compared to the current rotational speed of the earth, solar system, and galaxy (nevermind the other factors of life not working without rotation and such.)

Thank you for answering my question! It's for science because I'm a med student currently in my psych rotation and I'm writing a paper on emotional affect with an interest in blunted affect and how blunted affect can appear as a coping mechanism (and many other forms) in neurotypical human beings vs people suffering from autism and psychopathy.

Alright boi, im the other admin and unlike her I’m just fucked up in the head lol

Sink used for Acid Fast Bacilli Kinyoun stain. This is at the lab I’m currently doing my rotations at and I thought it was pretty.
Mycobacterium tuberculosis, the causative agent for Tuberculosis or TB, has a cell wall that’s high in lipid content. So, it doesn’t stain with regular gram stain; thus, they used acid fast staining techniques with carbolfuchsin.
