@Gkov1111 @earthcurated The Earth is round. The wide-angle Len might emphasize it some, but Earth’s curve is there.
Notice the equipment in space doesn’t look all warped from the lens.
English

@earthcurated You see that curvature … is because the camera lens is round, so it creates a visual effect that Earth is round too

A professor of engineering who failed math all through school built one of the most popular online courses in history by figuring out exactly why her brain had been working against her the whole time.
Her name is Barbara Oakley, and she did not teach herself how to learn until she was in her mid-twenties, after leaving the military with a head full of Russian and almost no useful science knowledge. What she discovered about her own brain eventually became a Coursera course that over 4 million people have taken, and the core insight she teaches has been sitting in neuroscience research for decades waiting for someone to explain it in plain language.
Here is the framework that changed how I think about every hard thing I am trying to learn.
Your working memory is an octopus sitting in your prefrontal cortex with exactly four arms. Those four arms reach out and grab pieces of information, hold them in place, and manipulate them while you are actively thinking through a problem. Four is the limit.
When you try to hold more than four things in conscious awareness at once, the arms start dropping things and everything becomes a scramble which is exactly what you experience as confusion when learning something genuinely difficult.
This is not a flaw. It is a design feature. And the entire game of becoming expert at anything is learning how to game this constraint.
The mechanism is something neuroscientists call chunking, and it is the most underexplained concept in all of learning.
When you practice something enough times that it becomes automatic a guitar chord, a grammatical structure, a mathematical procedure, a debugging pattern in code your brain compresses it into a single neural package stored in long-term memory. That compressed package now fits in just one of your four working memory slots instead of filling all of them.
Which means once you have built enough chunks, your octopus can reach down into long-term memory, pull up an entire complex procedure in a single grab, and still have three arms free to work with new information on top of it.
This is what expertise actually is. Not raw intelligence. Not natural talent. A library of compressed patterns that can be retrieved quickly and stacked together to solve problems that would overwhelm a beginner whose working memory is still occupied with fundamentals.
The finding that Oakley emphasizes most forcefully is the one that sounds backward until you understand the mechanism. People with smaller working memory capacity those who can only hold two or three items at once rather than four are often forced to develop stronger chunking habits earlier and more aggressively than people with larger working memories, because they have no choice. Their constraint becomes their training. Over time, that aggressive chunking practice can produce more robust expertise than a larger working memory that never had to be disciplined in the same way.
The most powerful practical implication is this: when you feel completely overwhelmed trying to learn something, that feeling is almost always your four-slot octopus running out of arms. The solution is not to concentrate harder. The solution is to stop, isolate one small piece of the problem, practice it until it compresses into a single chunk, and only then pick up the next piece.
You cannot learn everything at once because your brain was never designed to hold everything at once. It was designed to build libraries of compressed knowledge and retrieve them on demand.
Every expert you have ever admired is not smarter than you. They just have a bigger library.

🚨 let me tell you what just happened because I'm sure most people completely missed this..
Kamal Kharazi was Iran's lead negotiator.. the man actively working through Pakistan to arrange a backchannel meeting between Iranian officials and JD Vance.. the only active diplomatic channel that existed to prevent what Trump called a "2 to 3 week" strike window..
Israel just bombed his house.. his wife is dead.. Kharazi is in hospital..
and you need to pay attention to the timing..
this isn't the first time Iran's negotiators have been killed right before a deal could be made..
Mohsen Fakhrizadeh was Iran's top nuclear scientist and the man considered most essential to any future nuclear negotiations..
he was assassinated in November 2020, widely attributed to Israel.. the nuclear talks were set back by years.. in 2012, Mostafa Ahmadi Roshan.. a senior figure at Iran's Natanz enrichment facility.. was killed in a targeted car bombing in Tehran, also attributed to Israel.. the pattern holds every single time..
every time Iran and the US get close to talking, someone removes the people doing the talking..
Trump said 2 to 3 weeks.. someone in Iran was actively building the exit ramp from that window.. and today the man building that exit is in hospital and his wife is in the ground..
whoever bombed that house wasn't trying to win a war..
they were trying to make sure there isn't a peace.

BREAKING: Kamal Kharazi has been seriously wounded after Israeli strikes hit his home, killing his wife. Kharazi had been the lead negotiator involved in backchannel efforts with Pakistan to arrange a potential meeting between Iranian officials and JD Vance, per Aljazeera

@unusual_whales This means Israel has a mole within the US Administration.
English

@Investinc_Intel @unusual_whales The strait is one of Iran’s biggest playing cards.
The talks were probably happening because of the strait.
Maybe war shouldn’t have happened at all?
And maybe Israel doesn’t want talks.
English

@unusual_whales Well, maybe next time they won’t weaponize the strait in negotiations.

BREAKING: Pam Bondi FIRED as AG, Trump tells Fox

FOX CONFIRMS PAM BONDI OUT AS AG TODD BLANCHE TO BE INTERIM AG

@MillerElbob @TheNationalMall @SaraCarterDC @Freedom250 @NASA They have future plans to do more than just circle the moon. The ultimate goal is Mars. There’s a lot of new technology involved, so they have to test things first just like they did with Apollo missions. Artemis II takes humans farther from Earth than they’ve ever been. 🤩
English

@TheNationalMall @SaraCarterDC @Freedom250 @NASA I’m as thrilled as everybody but have a question. Why are we circling the moon. We have put people on the surface of the moon 6 times. Only nation in world to do that so why are we spending $ just taking a moon lap?

@CatsEyes00 @Angry_Staffer I don’t think you know what the word narcissist means. Because the original poster hasn’t demonstrated it but the president sure as heck has.
English

@Angry_Staffer As for the Iranian people crying for freedom, who wanted to hear the speech but were unable to because the regime has cut them off the from the world...? You couldn't give a damn. You self-absorbed noisy American narcissist.
English

@CatsEyes00 @Angry_Staffer Can you please describe to us in what way Donald Trump has helped the Iranian people to have freedom?
Because they don’t have it.

SAVAGE TAKEDOWN — AGED LIKE FINE WINE:
One of the most brutal political takedowns in American history.
Watch Jamie Raskin absolutely demolish Byron "The GOP Butler" Donalds — exposing his constitutional illiteracy and pathetic Trump bootlicking in real time.
Raskin went full savage mode, and Butler Donalds couldn't even finish his shift at the table.
This is your candidate for governor, Florida? The man who confuses the Constitution with a Trump rally flyer?
Dems hit harder… MAGA comes with rehearsed talking points and a fragile ego. Watch the Butler get schooled on camera.

@AmoneyResists @elonmusk @realDonaldTrump @Starlink I miss the days of real Twitter.
That “politically neutral” part sure as heck didn’t happen.
Mush does it all for his own personal interests, just like the spray-tan guy.
English

.@elonmusk and @realDonaldTrump made a deal to avoid prison. Musk would hand Trump the presidency using @Starlink. Trump would give Musk the authority to shut down agencies investigating him, award himself gov’t contracts, pilfer our data, and steal our Social Security/Medicaid.

@JohnLBria @HQNewsNow “We have to take care of one thing, military protection. We have to guard the country.”
So that’s all you think the federal government should be doing?
Using the military to guard the country?
You’re giving up your Social Security and Medicare for that?
English

@HQNewsNow @designmom Yikes.
I’m thinking …
Oh, just never mind.
Was going to use some facts and logic, but ..,

The White House has removed this video from their social media channels.
But not before we could post it.

Trump: We can't take care of daycare. We're a big country, we have 50 states, all these people, we're fighting wars. It's not possible for us to take care of daycare, Medicaid, Medicare, all these things

@AmberBrooks619 My Dad thought apple cider vinegar would bring his cholesterol under control.
I did not.
He should have kept taking his statin!
Stop misleading people.
Apple cider vinegar it isn’t a cure all. Go ahead and drink it, but don’t stop taking your prescriptions.
English

Ozempic made billions off women desperate to lose weight, leaving them with nausea, fatigue, and saggy skin.
They don't want to fix your metabolism; they want you dependent on expensive monthly injections.
Reject their racket with Apple Cider Vinegar... twitter.com/i/web/status/1…
