Replying to @KaivanShroff
I’ve worked around comics and writers for nearly 4 decades and I’ve never seen anyone fact check a white comic’s specials like this. If you need proof of racism, this explanation is it. Creative license exists for a reason, he’s a comedian, not a journalist. Wow this all sucks
This episode of the Empire podcast by @DalrympleWill and @tweeter_anita goes into fascinating details. They gave up on California just before the Gold Rush and sold Alaska just before the discovery of gold and other resources. podcasts.apple.com/gb/podcas…
The costliest mistake in human history is often considered to be Russia selling Alaska to America. This sale was driven by the Russian Empire's difficulty in maintaining control of Alaska, facing threats from the British Empire at the time. The negotiation resulted in a purchase price of $7.2 million, equivalent to $123 million today or about 2 cents per acre.
The official transfer ceremony occurred in Sitka on October 18, 1867, with a parade of Russian and American soldiers. The Russian flag was lowered, and the American flag was raised. At that time, Russia was unaware of the valuable resources lying beneath Alaskan soil, and they feared the purchase would threaten British control of their Pacific coast colony.
Approximately 20 years later, in the 1890s, oil was discovered in Alaska. It's estimated that there are around 1.2 billion barrels of oil in the region, along with an estimated 53 trillion cubic feet of undiscovered natural gas, making the oil alone worth approximately $85 billion dollars today. To put this in perspective, Alaska is more than seven times the size of the UK.

This is the Pepper X.
It was just crowned the world’s hottest pepper, hitting a Scoville Heat Unit (SHU) of 2,693,000.
Here are other SHUs for comparison:
▫️Red bell pepper: 0
▫️Frank’s Red Hot Sauce: 450
▫️Sriracha: 2,000
▫️Tabasco: 5,000
▫️Jalapeño pepper: 8,000
▫️Cayenne pepper: 30,000
▫️Pepper Spray: 2,000,000
SHU measures the number of times the capsaicin content in a chili pepper needs to be diluted before it is no longer detectable.
For example: Tabasco needs to be diluted 5,000x while Pepper X needs to be diluted over 2,000,000x (the previous record-holder was Carolina Reaper pepper, which has a SHU of 1,641,183).
Both Pepper X and the Reaper — which held the title from 2013 to 2023 — were created by Ed Currie, a pepper breeder based in South Carolina.
Each took about ten years to make using a selective plant breeding process.
Last week, “Hot Ones” Sean Evans hosted Currie and tried a Pepper X.
My takeaway: There is literally no amount of money you could pay me to eat one.

This is a painting depicting Elihu Yale (center), the founder of Yale University, ca. 1708. Perhaps, most noticeable is the depiction of the enslaved boy on the right with a silver collar.
The Yale Center for British Art provides some more context:
"Nothing is known about the boy on the right, who has just finished pouring Madeira (a sweet, fortified wine) into the glasses on the table. His fine red and grey livery (or uniform) identifies him as a servant, and the silver collar and padlock around his neck indicate that he is enslaved. At the table sit Elihu Yale (center), William Cavendish, second Duke of Devonshire (right), and his younger brother James Cavendish (left). The portrait.. is believed to commemorate the signing of a marriage contract between Yale's daughter, Anne, and James Cavendish."
Yale was a British American merchant who made most of his wealth from enslaving people and stealing from Madras (now Chennai), India.
"In the 1680s, when Yale served on the governing council at Fort St. George on the Madras coast, a devastating famine led to an uptick in the local slave trade. As more and more bodies became available on the open market, Yale and other company officials took advantage of the labor surplus, buying hundreds of slaves and shipping them to the English colony on Saint Helena."
In 1692, Yale was removed from his position due to charges of corruption. He was forced to pay a fine but was still permitted to take a sizable fortune back home to England. In 1719, Yale donated several hundred books to a Collegiate School in Connecticut, which was later named Yale.
In 1999, when Yale University celebrated Yale's 350th birthday, American Heritage magazine published an article declaring Elihu Yale as the "most overrated philanthropist" in American history. In fact, much of the school's success can be attributed to Jeremiah Dummer, who was instrumental in raising the funds needed for the school to flourish. Unfortunately, the trustees of the school did not want to name it "Dummer College."
Imagine that QBs have an AR lens on their helmet that highlights this.

If you live in the Bay Area and love animals, I'm wondering if I can get your help. A friend in San Jose has trapped three of five stray kittens. And she's trying to find them a home. If you're interested, can you drop me a note below? Or spread msg to Bay Area friends.
Always love the threads from @Paperclip_In - esoteric, but fascinating topics that I didn't realize I was curious about until I read them.

For anyone here who hasn’t worked in corporate strategy at a Fortune 500 company and wants to understand how utterly bone-headed decisions—such as changing your customers’ cell-phone plans unless they proactively call to opt out—get made, here’s a quick explainer 👇
This chain of events typically starts during a quarterly board of directors meeting, during which an independent director (generally a current or retired CEO of a company in a different, non-competing industry) says that the company isn’t making enough money and that it’s the fault of the CEO, who is a supremely unqualified buffoon.
(Tangent: Every board director has his own pet favorite metric, be it growth (e.g., year-over-year sales), profitability (e.g., EBITDA margin), investor returns (e.g., change in share price if public, return on invested capital if private), or some byzantine metric that he used to love when he was the division president of a Ma Bell carve-out back in the 1980s (e.g., change in same-store gross profit divided by number of people on the sales team, raised to the power of pi and divided by 1998, which represents the year his current girlfriend was born). The exact metric doesn’t matter; what matters is that, by the standards thereof, the CEO sucks.)
The independent director will then pull open the calculator app on his iPhone 7, punch some numbers in, and say something to the effect of, “If we can increase revenue per customer by just $5, our market cap will increase by billions. Get your strategy team to figure it out.”
From here, the CEO and the CFO will then set up a meeting with the SVP of corporate strategy for 7:15 AM the next morning, to be held in the locker room of the country-club whose $20k annual membership dues the company’s shareholders generously cover. Sitting in the sauna, buck naked save for bleached white towels barely sufficient for the mission to which they’ve been called, the executives will decide that the most prudent course of action is to call McKinsey and pay them approximately $2.5M to figure this out for them. (Note: The CFO will get a quote from his buddy at Deloitte or KPMG, just to be able to tell the board that they solicited competing bids, but everyone knows that the work is just going to end up with McKinsey. Or Bain.)
McKinsey will rapidly set up office in a large conference room on-site, as if it’s the makeshift command-and-control center of an air base in Kuwait on the eve of Operation Iraqi Freedom, and they’ll deploy a dozen MBAs with a weighted average age of 26.5 years across the company’s headquarters. The consultants will meticulously evaluate all levers for revenue growth, including M&A, organic growth from new customers, and organic growth from existing customers (either by reducing churn or just finding ways to get more money out of each one). M&A will quickly get crossed off the list, since McKinsey doesn’t want Goldman coming in and taking over, and new-customer growth is always just painful, so, by process of elimination, they’ll decide on getting more money from existing customers.
After performing an analysis called a customer segmentation, McKinsey will realize that the company has already squeezed every last dollar possible out of the company’s highest-paying customers, whose loyalty is already pushed to the limit. They will therefore instead try to figure out how to get more money from lower-paying customers.
Associate 1: How do we get more money from our cheapest customers?
Associate 2: Can we go back to selling ring tones, like we did in 1998?
Associate 1: I did a case study on that at HBS! Ten minutes go by. Anyway, that’s why it won’t work. What if we just… raised prices?
Associate 2: These customers are highly price-sensitive. We can’t do that unless the customers think they’re getting additional value.

Beautiful analogy
Imagine that you have a piano keyboard, and each key corresponds to a possible location of a particle. The Schrodinger equation tells you how to play a melody on this keyboard, using the wave function as the sheet music. The wave function gives you the amplitude and frequency of each note, which represent the probability and energy of finding the particle at that location. The higher the amplitude, the louder the note, and the higher the frequency, the higher the pitch.
The Schrodinger equation also tells you how the melody changes over time, depending on the potential energy of the particle at each location. The potential energy is like a tuning knob that affects the frequency of each note. If the potential energy is high, the note becomes sharper, and if it is low, it becomes flatter. The Schrodinger equation describes how the wave function evolves in response to these changes in frequency, and how the melody becomes more or less harmonious.
The equation is very important in quantum mechanics, because it allows us to calculate the wave function for any physical system, and use it to predict the outcomes of measurements. However, unlike classical music, quantum music is very unpredictable and probabilistic. We can only know the average values of observable quantities, such as position and momentum, but not their exact values for any given measurement. Moreover, we can never know the wave function completely, because every time we measure it, we disturb it and change its shape. This is known as the collapse of the wave function, or the quantum jump.
It was discovered by Erwin Schrödinger in 1926, and it is based on the conservation of energy. It is a partial differential equation, which means that it involves derivatives of the wave function with respect to both space and time. It can be written in different forms depending on whether we use a fixed or a moving frame of reference. It can also be generalized to include relativistic effects, such as when particles move close to the speed of light.

"I am...on a train from Madrid to Barcelona. The journey takes 2½ hours and covers more than 300 miles, approaching the distance between London and Edinburgh. I paid €19"
80% of trips between those cities are now rail. It was Europe's busiest air route
