How Do Classical And Quantum Physics Complement Each Other?
Classical physics, pioneered by legendary figures like Newton and Maxwell, reveals an orderly clockwork universe with precise mathematical laws governing motion, gravity, and energy. However, in the early 20th century, the emergence of quantum physics uncovered a microscopic realm where uncertainty, probabilities, and spooky connections reign supreme.
For decades, these two frameworks seemed…

Fundamental Differences between Quantum Mechanics and Classical Physics
Quantum mechanics is a branch of physics that deals with the behavior of matter and energy on the smallest scales, such as individual atoms and subatomic particles. It is a fundamental theory that has been extremely successful in describing the behavior of the microscopic world and has led to a wide range of practical applications, from quantum computers to medical imaging.
However, quantum…
the fact that shakespeare was a playwright is sometimes so funny to me. just the concept of the "greatest writer of the English language" being a random 450-year-old entertainer, a 16th cent pop cultural sensation (thanks in large part to puns & dirty jokes & verbiage & a long-running appeal to commoners). and his work was made to be watched not read, but in the classroom teachers just hand us his scripts and say "that's literature"
just...imagine it's 2450 A.D. and English Lit students are regularly going into 100k debt writing postdoc theses on The Simpsons screenplays. the original animation hasn't even been preserved, it's literally just scripts and the occasional SDH subtitles.txt. they've been republished more times than the Bible
In classical mechanics, every configuration has one in arrow and one out arrow.
With a system like this, life gets very boring. But Susskind battles this with his consumption of cookies.
Cookies go in, classical mechanics knowledge comes out!

The Time Travelers
My branch bank was closing. The nearest location was three miles away. I don’t own a car so the distance was significant. Needing to learn how to make future deposits, I stopped by the office to learn about options. The acting manager greeted me with a smile and waved me into her office as I entered. Except for the clerk at the reception desk, we were alone. Sliding into the plastic chair she indicated, I noted her desktop was clear, except for a phone, and a computer, beside which sat a notepad and a glass jar crammed with multicolored pens. She splayed her fingers across the walnut surface as she sat opposite me, her eyes wide with anticipation. No doubt, I was a welcome distraction in an otherwise hum-drum day. I noted she was young, barely a year or two beyond her teens with a smile that left no wrinkles at the corners of her upturned mouth. A distance of 70 years stretched between us, I guessed. When I told her why I’d come, she looked relieved. “Check deposits? That’s easy.” She chirped out a couple of choices. With a debit card, I could make deposits at any ATM. Or, if I preferred, the app on my smartphone would perform the same magic. She might as well have been speaking in Swahili. “I have neither a debit card nor a smartphone,” I explained. “What I want is a mailing address for my deposits” The woman behind the desk took in a sharp breath as if I’d shoved a knife between her ribs. “Mail deposits? We don’t accept those.” I frowned. She was speaking Swahili again. “Are you sure? Things can’t have changed that much. Could you check with the head office?” A pair of youthful shoulders shrugged– a sign designed to discourage me. Nonetheless, the young woman picked up the phone and dialed a number. I held my breath while it rang. A brief exchange followed between the caller and a voice somewhere in the ether. At last, the woman seated opposite me hung up, turning a pair of owlish eyes in my direction. “ I had no idea we did mail deposits No one’s ever asked.” She tore a page from her notepad and wrote down a P. O Box number which she handed to me. Leaving the office with a light step, I was glad I had persevered. Even so, I sensed a pair of blue eyes at my back as I exited. No doubt the twenty-something person I’d left behind thought I was a relic that needed to be stored in a box in the bowels of the Smithsonian. She might be right. Time is a tricky thing. In the everyday world, it moves at the speed of light in a single direction. But time in the human brain is flexible. My thoughts can take me backward and forward in history. The same is true for my young banker. The difference between us is that she lives in the violet spectrum of now, while I and my memories have decayed into the red zone. We are creatures of the same universe, yet she and I exist in dissimilar energy fields. The laws of physics decree that when different fields can be described by the same mathematical structure, rapid advancement of knowledge takes place in which the two fields cross-fertilize. So it was with the young woman and me that afternoon. I saw her as limited in knowledge. She, no doubt, saw me as obsolete. Even so, by the time we parted from one another, we were both wiser. Youth and age are frequently out of tune with each other, the way classical physics and the quantum world appear to conflict. Call it an atonal harmony, the kind the gravitational force field makes when it suffers a disruption and sets the universe to humming. I think of that humming as the music of a higher order. If humans were to penetrate the deepest secrets of that harmony, where would they take us? We saw the effects of harnessing nuclear power. It ended World War II and gave us clean energy. But it also helped to deplete the ozone layer, raise global temperatures, and hasten the effects of global warming. The mind is a terrible thing to waste, yet curiosity comes with a price. We embrace Neurotech devices that measure metabolic functions to retain good health, but surveillance capitalism, like nuclear energy, has a downside. At any time, our private information can be made public. China, for example, requires some workers to wear EEG sensors to monitor their productivity and emotional states. Can we be sure the demand for brain transparency won’t one day deny us the right to private thoughts? Advances in Artificial Intelligence (AI) have led some theorists to speculate that one-day homeo sapiens might become obsolete. Bionics are already widely accepted. Pacemakers are common as are artificial joints, cochlear implants, and intraocular lenses. This evolution has come softly on cat paws and with each progression we blur the line between robots and humans. My young banker knew nothing about mail deposits, having no historical memory. In the future, will it be the same with our acceptance of robot technology? And should AI become sentient how will we view our creation? With fear? Or, in our quest for eternal life, will we download our memories into an avatar? Should we choose to merge with robots, will we still be human? What will become of our unconscious minds? Will we dream?
My professor just mentioned a cool quantum physics topic before continuing to teach our boring classical physics content. I feel like a toddler he dangled a piece of candy in front of and then snatched it away at the last second I hate it here
This video is doing numbers on TikTok, but I wanted to share it here because I am so proud. The man being featured is my uncle Steve Smith.
Steve has been building drag racers & custom cars his entire life.
My grandma before passing away would tell the story of how when he was 10 or 11 years old - she came home to him taking apart the engine in her secondary vehicle (reserved for fancy outings).
She asked him why & he said he wanted to know how it worked outside of a schematic. & she told him that as long as he put it back together the way he found it, it was fine by her. & what's more - he put it back together from memory without even looking at a diagram!
If anything went wrong with the car, my grandma had him fix the car & it was that way until my grandma passed away. She never paid for a mechanic in her life again.
When Steve was a teenager he spent most of his time at the OKC Racetrack & raced with drag racers he built himself.
Also, as a teen he won the Bethany, OK wheelie championship by riding over a mile nonstop on his motorcycle on a single wheelie position.
All throughout my childhood he always had cars around in various stages of fixing up.
The city of Bethany refused to sell him the property next to his house to open his own auto garage. He had worked for Diffee Motors most of my life up until then. So he moved out in the country & opened his own garage.
Steve has been on several mainstream auto shows being featured for his custom work. He also built a custom car for one of the guys on Duck Dynasty. He was also offered a permanent role on an auto TV show, but he turned it down because it required moving out of state.
My uncle Steve is one of the sweetest, kindest & most generous people you will ever meet in your lifetime. He's as smart as a whip, has never met a stranger & gives the best hugs!
It just makes me so happy to see him getting the recognition he deserves.
The picture below is of him at a family function sitting next to his wife, Nancy.
big fan of how classic who doctors are like "i will defeat this opponent with my intellect and skills" and then they beat the shit out of said opponent
Greygold could totally take on their team 1-9. Totally. With 8+ summons and carrying a 10-year-supply of inventory items, Greygold IS the BBG babe's love fight don't count because Greyg didn't wanna fight shh
As much as I don't like where this fork-in-the-road went, boy did I have a lot of time to mull over why squid buddy called it quits. And I couldn't pick just one reason ✨
So let's kick it up a notch with the survival theory.
After hearing how certain mindflayers get the instinctual hankering to be a lil shit that sometimes they gotta roll a dice so as to NOT be a lil shit....
What if. Maybe squid buddy's mindset wasn't just being dead stubborn about surviving, but the exhausted-flayer's survival instincts kicked in. Maybe there was poor communication because Emps was in panic mode, wits at an end, fear on overddrive, every doubt collapsing in on itself, stuck-in-a-corner mode, eye-for-an-eye contemplation, fight-or-flight response overriding any other sensible dialogue options that were available for them.
Maybe Emps failed their don't-be-a-lil-shit roll
And since squid buddy didn't uh....want to repeat the fight response like with Ansur, for various reasons, reacted with flight instead
Funny story, I drew this a while back as a 'fun' theoretical possibility, but been realizing more recently ehhhhh-Emps really coulda just killed us all right then and there (not withstanding Halsin and Jaheira). If Emps had the ability to turn off the mind-protection after you stray too far from the mission, then they coulda done the same thing to everyone now. So if Emps really had a "no more use for us" mindset like a certain mindflayer book says they do, fleeing wasn't necessarily the only way for Emps to survive.
Maybe. Emps was about to react in a way they knew they were gonna regret again and eeehh- counter-reacted by noping the fuck out. For Greygold, I like that theory. Squid Buddy: jumping the gun like a dramatic tired mindless-flayer
