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)…

Disclosure

Question for my fellow third years: Do you tell your attendings or residents what field you want to go into, even when that’s the rotation you’re currently on?

I’ve heard mixed reviews about telling people the field you want to go into on your rotations. On one hand, it shows them that you’re interested and engaged, but on the other hand I’ve heard that it could burn you if they decide to evaluate and critique you harder because they know you want to go into their field.

So far I’ve told my two attendings that I’ve worked with on inpatient that I thought I was interested in peds, but today I told my new intern that I wanted to do inpatient work. I’m just not sure how to field those, “What do you want to do with your life?” questions.

Always Right

A Reference Material Verse Ficlet 


She’s drifting on the edge of consciousness when he puts his knee on the bed and crawls beside her, rocking her into full awareness. He fits his body to hers, his chest warm at her back, his jeans scratchy against her bare legs, but she doesn’t shrug him off or elbow him away. He’d already been out of the house when her shift ended, and she’d missed the opportunity to curl up with him and reconnect.

She can’t wait for her current rotation to be over; albeit it’s good practice for what’s to come, the graveyard shift – even on desk duty – is nothing short of exhausting.

“Sorry,” her husband rumbles, dusting an apologetic kiss to the curve of her neck. “Didn’t mean to startle you.”

“You’re ‘kay,” she hums, swiping sleep from her eyes. Her fingers come away dark with the remnants of her eye makeup, reminding her how little attention she’d paid to doing anything but getting changed into her pajamas when she got home. “I locked the door behind me, didn’t I?”

Rick chuckles, leaning over her shoulder to steal a kiss from her mouth. It’s a little sloppy with her drowsiness, and the angle is weird, but she smiles against his lips anyway. “'Course you did. Though your keys ended up dangling off the table instead of in the bowl.”

“Whoops,” she exhales. “Little bit out of it; I forgot to take my makeup off, too.”

He nods, skimming his fingers down her side. “Rough shift?” he asks, thumbing the curve of her waist.

“Just long,” Kate explains. Her fingers fumble for his, eager for the heat of his palm and the splay of his fingers over her belly, eager to feel their child’s kicks and flutters. “Cap'n had me doing paperwork until I couldn’t see straight.”

Rick nods, tapping the curve of her stomach with his index finger. His greeting goes unanswered; the baby must be sleeping, finally settled after spending most of the night nudging her while she worked.

“Sounds boring.”

She laughs. There’s nothing exciting about filing reports, especially given that she’s not the one collecting most of them, but it’s a small price to pay. If she’s going to make detective soon, she’ll take all the grunt work she can get. “I got to watch an interrogation, though. From the observation room.”

That perks him up. “Hey, that’s cool. Was he the perp?”

Kate hums, squeezing his hand. “She was. She whacked her husband with an umbrella because she found out he was having an affair.”

“Oh, sounds like he won’t be singing in the rain again.”

She shouldn’t laugh, but she can’t help the chuckle that spills from her lips. “No, he’s pretty well covered and quiet now.”

Rick grins against her shoulder. “Good one. Hear that, baby? Your mommy’s really embracing that cop humor.”

It shouldn’t please her to hear that, but Kate can’t help the thrill that rolls up her spine. She’s been out of the academy for over two years, but still feels like a rookie in many respects. She works every single day to prove herself, so any indicator that she’s fitting in helps. Especially on days when she wonders if anyone at the precinct sees more than just a belly in a uniform.

“The donuts, too,” she adds wryly, rubbing a slow circle under her navel. “But we won’t talk about those, or I’ll be sending you out to buy me more.”

Rick snickers at what a cliché she has become, bumping his hips against hers as he slides closer. “I can if you want.”

Kate grins into her pillow. Her sweet husband, always ready to get her what she wants – no matter how illogical the request. “No, just stay here and tell me what Black Pawn said about the book.”

She expects bad news based on the way he falls silent, but his next words aren’t shriveled and coated in disappointment, instead they’re awed.

“They said sales are through the roof. They want to arrange for another printing, and start marketing it more heavily overseas.”

She turns, flinging her arm around him, her lips already seeking his. “That’s amazing, Rick. I’m so proud of you.”

He’s almost bashful about it, holding her cheek and keeping her close for another kiss. “Thanks, Kate. I have to admit, I was stunned when they told me.”

“You shouldn’t be,” she chides, stroking the shell of his ear. “You’re so good at what you do; they’re lucky to have you as their author, and after six – soon to be seven – books, they damn well better know it.”

His lips curve against hers, amused at the ferocity of her defense. “I’ll let you be the one to remind them, should they ever forget,” he assures, nudging her to settle against her pillow once more.

“I’ll do it,” she confirms, resolute. “But they’ll have more than just me to contend with, I think.”

Reaching back, her fingers flutter against his jaw before she seeks out his hand, covering the swell of her belly where their child – his number two fan – kicks.

“I think you’re probably right,” he murmurs, puckering his lips against her shoulder.

“Of course I am,” Kate scoffs. “I’m always right about you.”

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

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.

"Some Personal Recollections." Short autobio by Nikola Tesla *audio*

Listen to “Some Personal Recollections.” A short autobiography written by Nikola Tesla, in 1915, explaining his personal life, which lead to his discovery of the rotating magnetic field, and the development of his alternating current induction motor.

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.)

tw: abortion mention I'm currently in my clinical rotations for medical school and one of my fellow students refused to watch a video of an abortion procedure because it's "sinful" and some other anti-choice rhetoric. It's a medical procedure, if you can't accept it, maybe you should reconsider whether you want to become a doctor or not!

Wow, med school requires you to learn about and understand basic medical procedures? Mind = blown

I started making these bralettes solely out of frustration. I’ve been crocheting for a few years and I never see anyone who makes bralettes and crop tops like these making them any larger than a 36D. As a plus size girl, I always thought this was ridiculous. I worked at perfecting these for over a year now and I’ve finally been selling them on Etsy. However, it turns out selling them on there isn’t as easy as I thought. I just want to provide plus size women, and really all women of all shapes and sizes, the option to wear things like this and have them fit their specific needs. So if anyone is ever interested, don’t hesitate to let me know or to just go ahead and make a purchase from my Etsy shop. I have a handful of designs currently in rotation with many more to come in the upcoming weeks!
