snoop dogg grabbed a knife, hid under a blanket, and rode a 5-hour flight in silence next to his best friend.

it was the last time he'd see tupac alive.

snoop grew up in long beach. at 12, he joined a gang. "drugs and gangs were as much a part of your life as stop lights and street signs." his mom kicked him out at 17.

then he met tupac. "fell in love with that man. we started building a brotherhood. the calm one and the relentless one."

snoop thought he was untouchable – until his bodyguard shot and killed a man. snoop turned himself in for first-degree murder. suge knight bailed him out on a million dollar bond. 10 p.m. house arrest.

tupac wanted him to stay gangster. snoop: "I got a baby on the way. I have a lot to live for. somebody's life was lost. I don't want to live this gangster life no more."

verdict: not guilty.

then the east coast/west coast beef exploded. tupac was convinced biggie and puffy set up his shooting. snoop never believed it. "they was his friends at the time."

tupac dropped a diss track saying he slept with biggie's wife. snoop: "I ain't really feeling that, cuz. he took it too far."

then angie martinez asked snoop on air: how do you feel about puffy and biggie? he said: "I'm cool with him. I want to do some music with him."

tupac took it as betrayal. "death row looked at me as a traitor. you had sided with the enemy."

the plane ride back to LA – 5 hours on a private jet. tupac didn't say a single word to him. snoop got off the plane: "cuz, you going to vegas?" tupac brushed him off. went his way.

next call snoop gets: "turn on the news."

tupac shakur was shot four times in a drive-by.

snoop drove to the hospital. "I'm thinking he's going to make it. when I went to go see him – that ain't what I got. he wasn't moving. he wasn't talking. he wasn't breathing on his own."

tupac's mother pulled him aside. told him to be strong. that's when snoop knew.

"I got right on the side of his head and just started whispering to him. telling him I loved him. to hold on. he was going to be okay."

snoop went to the bathroom. fainted. threw up.

"me and my homie wasn't straight. I'm not even going to be able to apologize to him. or just tell him – I feel you. I'm wrong. how can we fix this?"

tupac died at 25.

compton erupted. 12 shootings. a 5-day blood bath. three men dead. ten wounded. "we was right in the middle of all that madness."

snoop looked around. "all of the rappers that was writing about death – they all dead. I got a baby. I got a wife. I wanted to live."

"my life is not based off me being a gangbanger. it's based off me being positive. finding ways to help others. the key to this thing is bringing people together."

"pac was taught how to love at a very early age. and through his music, he shared the love with all of us."

snoop chose peace. and never got to say goodbye.

Dame Dash and Jay-Z built Roc-A-Fella Records from nothing. they were brothers. nobody wanted to sign Jay, so they created their own label and made him famous.

"Jay's my best friend. I'm not ashamed to say it."

then Dame fell in love with Aaliyah. it started as a friendship. "our intention wasn't even to be in love. it was almost an accident."

but Aaliyah was still healing. at 15, R. Kelly had secretly married her. Dame knew everything. "we talked about it up to the point where it hurt." she'd just say: "that's a bad, bad man."

Aaliyah asked Dame one thing: leave it alone. don't start anything with Kelly. let her heal. he respected her wish.

August 2001: Aaliyah flew to the Bahamas to shoot a music video. her last text to Dame: "I don't like the plane." he replied: "don't get on." she got on.

the plane crashed minutes after takeoff. Aaliyah was 22.

"if I'd have been an asshole that day and really stood behind what I believed in, she wouldn't have got on that plane."

five months later, Jay-Z released a joint album with R. Kelly. Best of Both Worlds. then a tour. t-shirts. merchandise. everything.

Dame: "you know that I got a girl that your man r**ed. I tell you. and you're gonna still work with him. what you think I felt?"

Jay's response: "I mean, I wasn't there. I had nothing to do with that."

Dame couldn't speak out – he'd promised Aaliyah he'd leave it alone. so he watched his best friend tour with the man who abused the woman he loved.

the partnership collapsed. Jay became CEO of Def Jam. the media blamed Dame. "Dame is bitter. Dame burned bridges." Jay called it "growing apart."

for 20 years, Dame held it in. then the "Surviving R. Kelly" documentary aired. dozens of women came forward. Dame broke his silence.

"if people would've protected Aaliyah, so many other girls wouldn't have got touched. she was the sacrificial lamb. she didn't deserve none of that."

R. Kelly was sentenced to 30 years.

"there hasn't been one day in 20 years that I haven't heard her name, heard her record, or seen a picture of her. every single day she's present in my life."

someone asked Dame what people should remember about Aaliyah.

"she was magic. I never thought I'd see that magic again."

Priyanka Chopra seems to have a perfect life. A loving husband, a daughter, global fame. But her whole life she's been hiding. And when the media went after her baby – she finally broke.

Growing up in India, Priyanka had zero confidence. Boys followed her home from school. One jumped onto her balcony at night. Her father put bars on the windows and confiscated her jeans.

Her mom entered her into a beauty pageant without telling her. Priyanka saw the photos: "How can you send those? They're so ugly." She faked confidence and won Miss World at 18.

Then Bollywood happened. She starred opposite Shah Rukh Khan – India's biggest star. They became close. The media turned it into a scandal. "Is Priyanka having a secret affair with the married Shah Rukh Khan?" They were spotted together at 3 AM. She was photographed wearing his jacket.

Shah Rukh defended her: "The fact that a lady who's worked with me has been questioned, not shown the respect I show her – that's most disturbing." Priyanka stayed silent. That made things worse.

Then they went after her face. "Priyanka has gone under the knife." Reporters asked on camera: "Is that your original nose?"

The truth she revealed years later: she was 18, went to a London doctor for a sinus problem, and the bridge of her nose collapsed during surgery. It wasn't cosmetic. It was a medical accident.

Bollywood turned on her. "People not casting me. I was tired of the politics." She fled to America.

She met Nick Jonas at an Oscar's after party. He got on one knee: "Where have you been all my life?" She was 35, he was in his twenties. She wasn't looking for love. "I was afraid of getting my heart broken."

The media attacked. One article called her "a global scam artist." Others said she "rocks him to sleep like a baby." They got married anyway.

Then their daughter Malti was born dangerously premature. Hospitalized for 110 days. "She had so many tubes, you could hardly see a little face." Priyanka shut down. Nick held her by the shoulders. She said: "Just tell me what to do." He said: "Just get into the car with me."

Then the media went after the baby. They questioned the surrogacy. Said she "didn't give birth to her daughter." That was the breaking point.

Malti came home healthy. And Priyanka finally stopped hiding. "I come across as strong because my parents raised me to be a strong woman. But that doesn't mean I'm not vulnerable. That doesn't mean I don't have dark days."

She survived stalkers, Bollywood politics, an affair scandal, a botched surgery turned into a nose job rumor, and a media that called her a scam artist for marrying the man she loved. It took almost losing her daughter for her to stop pretending she was fine.

"The best shutdown to people who said I didn't belong – is to belong."

Traders on the floor made thousands of dollars in minutes by showing each other fingers. Not a metaphor. Literally - with their hands. One gesture meant a hundred contracts. Another meant a thousand. Wrong hand - margin call. This world is almost gone. But someone filmed it before it disappeared.

Rick Santelli - CNBC legend. Started as a trader in 1979 on the Chicago Mercantile Exchange. Gold, currencies, interest rates. Then became the face of financial television - 25 years of live broadcasts from the trading floor. In this video he walks into the pit with the TopStepTrader crew and shows exactly how it all worked.

The language of the pit is hands. Everything below the chin - buying. Above - selling. Fingers at your face - price. Fingers away from you - quantity. One finger - one contract. Fist at the forehead - ten. Another gesture - a hundred. Another - a thousand.

When CME and CBOT merged, traders from different exchanges ended up in the same pit. The problem: identical gestures meant different things. One guy shows a hundred – the other reads a thousand. "You're buying a thousand?" – "No, I'm taking a hundred." In a pit where a deal closes in one second, that mistake is real money.

Santelli demonstrates the math. One S&P 500 contract requires $2,500 in margin. You buy a hundred in the pit and sell five hundred on the screen and pocket a thousand dollars. Twelve hours of work. Some days the market rips 200 points up, the cash session closes, and in the next fifteen minutes the Market-on-Close orders trigger a ten-point drop. The brokers have client orders stacked - sell 500 on close. The bell rings. The pit explodes. A hundred sold. Two hundred. Done.

The name TopStep comes from the pit itself. The best traders stood on the top step – where they had the best view, the best prices, and the best chance of catching the order flow. Everyone below was fighting for scraps.

This was trading before algorithms. Before screens replaced humans. Before the pits went silent. A world where your voice, your hands, and your nerve were the only edge you had.

In March 1929 a banker named Paul Warburg stood up and warned America that an orgy of speculation would end in a depression involving the entire country. Wall Street called him a party pooper. Six months later the market crashed. The depression lasted a decade. Then came war. Warburg never recovered. His family believes the grief killed him.

They called him the Cassandra of Wall Street. Cassandra could see the future. She was also doomed to be ignored.

This BBC documentary traces how the greatest financial disaster in modern history unfolded – and why everyone saw it coming and did nothing.

It started with a new idea: ordinary Americans could get rich in the stock market. Charles Mitchell, president of National City Bank, spotted the opportunity. Millions had bought government bonds during World War I. Mitchell said – if they'll buy bonds, they'll buy stocks. He opened brokerage offices across the country. By the mid-1920s three million Americans were in the market. Shoe shine boys. Photographers. Comedians. Groucho Marx invested everything he had.

Then came buying on margin. You could buy a $100 stock for $25 down. The brokerage loaned you the rest. By the late 1920s 90% of a stock's purchase price was borrowed money. Nearly 40 cents of every dollar loaned in America went to the stock market.

Nobody regulated any of it. President Coolidge said the business of America is business. The government's job was to get out of the way. Wall Street insiders like Joseph Kennedy ran pump-and-dump schemes in broad daylight. It was legal. There were no disclosure rules. The market was a casino – and it was rigged.

October 24, 1929. Black Thursday. Stocks dropped 10, 20, 30 points at a time. Shrieks and gasps from the gallery of the exchange. Ten thousand people filled the streets outside. Four hundred mounted police were deployed.

The bankers tried to save it. Thomas Lamont of JP Morgan gathered five of the wealthiest men in America. They pooled $250 million. Richard Whitney marched onto the trading floor and bought 25,000 shares of US Steel above market price. It worked – for two days.

On Tuesday the selling was so relentless there was no lunchtime meeting at Morgan. By evening, American stocks had lost 22% of their value in 36 hours. $25 billion in personal wealth vanished in five days.

Then the banks started failing. Over 2,000 collapsed in 1931 alone. There was no deposit insurance. People went to withdraw their savings. The money wasn't there. They wrapped their feet in newspaper and slept in cardboard huts in Central Park. They called them Hoovervilles.

The crash didn't create the Great Depression by itself. But it triggered a chain reaction – banks failing, businesses losing credit, workers laid off, demand collapsing – that lasted an entire decade and spread across the world. In Germany it fueled the rise of fascism. In Russia it validated communism. American capitalism's worst failure became a recruiting tool for its enemies.

When Roosevelt finally took office he said one sentence that still echoes: the only thing we have to fear is fear itself. He guaranteed bank deposits. He launched the SEC. And to run it he picked Joseph Kennedy – the very man who had profited from rigging the market. The fox guarding the chicken coop.

MIT, 2007. An ordinary lecture on circuits and electronics. The professor writes a formula on the board and starts plugging in numbers.

A chip with 100 million gates, running at 1 GHz on 5 volts. He finishes the math, pauses, and turns to the class. The chip would burn 125 kilowatts just sitting idle, doing nothing.

That's enough to power a small building, coming from a single chip. He jokes about carrying a laptop like that in your backpack.

Then he asks the room how to fix it. A bigger resistor makes the chip crawl, and lower voltage isn't enough. For a moment it looks like the whole semiconductor industry is stuck.

The answer turns out to be simple: replace one resistor with a second transistor that does the exact opposite of the first. When one is on, the other is off, so current never flows straight from power to ground. Idle power drops to almost zero. This is CMOS, and nearly every chip in your phone and laptop is built on it today.

At the end of the lecture, the professor puts one tiny inverter on a live demo and starts raising the frequency. The temperature climbs until it hits 110 degrees and the transistor dies right in front of the students.

The question is: if one small idea saved the industry from 125 kilowatts, what will save it from the next wall?

The entire European theater of World War II – every single day, visualized on one map. From the first German tanks rolling into Poland in September 1939 to the final surrender in May 1945. Over 2,000 days of war compressed into minutes.

This is one of those videos that makes you truly grasp the scale of what happened. You watch the Axis powers swallow Europe whole – Poland falls in weeks, France collapses in just over a month, the Balkans crumble, and by mid-1942, Nazi Germany controls territory stretching from the Atlantic coast of France to the gates of Stalingrad.

Then comes the turning point. The Eastern Front, which consumed more lives than any other conflict in human history, slowly begins to shift. Day by day, you watch the Soviet green push westward. In the west, D-Day opens a second front, and the blue of the Allied forces begins squeezing Germany from both sides.

What makes this video so powerful is the day-by-day format. You don't just see the big events everyone knows – Stalingrad, D-Day, the Battle of the Bulge. You see the grinding, relentless pace of war. Some days, the front lines barely move. Other days, entire countries change color. You see Finland fighting its own separate war. You see puppet states rise and fall. You see neutral nations surrounded by chaos.

The color-coded system is brilliantly designed – Axis territories in shades of red and maroon, Allied powers in blue, the Soviet Union in green before and after joining the Allies, Finnish fronts in purple. Every shade tells a story: occupied territory vs. puppet states vs. daily gains and losses.

Roosevelt's voice echoes through the video – "a date which will live in infamy" – reminding you that behind every pixel changing color, there were real people, real decisions, and real consequences that shaped the world we live in today.

In 1933 one law split American banking in two. In 1999 they undid it. Nine years later the entire financial system almost collapsed. A Nobel Prize-winning economist explained in one Yale lecture how all three events are connected.

His name is Robert Shiller. Nobel Prize, 2013. He predicted the housing bubble before Wall Street saw it coming.

He starts with the thing most people get wrong. An investment bank is not a bank. You can't deposit money there. A pure investment bank does one thing – it helps companies issue securities. IPOs. Bonds. Mergers. Their entire business is reputation and trust.

Then he reads the principles of Goldman Sachs, written by chairman John Whitehead in the 1970s. First rule: the client's interests always come first. Their real assets – people, capital, and reputation. It sounds like a corporate brochure. Then this company became the most powerful investment bank in history.

Then the history. Glass-Steagall, 1933 – forced J.P. Morgan to choose. They picked commercial banking. Their fired investment bankers created Morgan Stanley. Two empires from one law.

Gramm-Leach-Bliley, 1999 – repealed the split. Banks could do everything. Nine years later Lehman collapsed. Bear Stearns was sold in a fire sale. Goldman Sachs – the Goldman Sachs – had to become a commercial bank to survive.

Then his former student walks in. Yale '02. Three years at Goldman. Now at Facebook. He tells the room: if working until 4 AM on a financial model twenty nights in a row sounds exciting – banking is for you.

The lecture is free on Yale OpenCourseWare. The understanding of why one law, written in 1933, still determines whether the global economy stands or falls – that's worth more than any MBA.

An MIT professor asked one question that no politician will ever answer honestly. Should the government support the lottery?

His name is Jon Gruber. Professor of economics at MIT. He helped design the American healthcare system. He wrote the microeconomics textbook half the country's econ students read before they graduate.

In this clip he puts the lottery on the board and breaks down exactly why people gamble - and why the answer changes everything.

The math is simple. A lottery ticket costs a dollar. It pays back forty cents on average. Negative expected value. Every time you play, you lose.

A risk-averse person would never take that bet. But millions do. Every week.

Gruber walks through the theories. Friedman-Savage preferences - people are risk-averse with small amounts, risk-loving with big ones. Sounds elegant. But 99% of lottery money comes from scratch tickets, not Mega Millions. The theory dies on contact with data.

Then the real split. Either gambling is entertainment - the thrill is in the utility function, people enjoy it, and the government should run lotteries as voluntary taxation. Or people are uninformed, making mistakes, and the government is sanctioning bad decisions.

We don't know which one is true. But the stakes are enormous. In some low-income communities people spend up to 20% of their income on scratch tickets.

Either the government is running a tax people enjoy - or it is selling bad math to those who can least afford it.

The lecture is free on MIT OpenCourseWare. The answer is still worth fighting over.

A quant educator at a $10 billion trading firm explained in one lecture how every option in the world is priced. He did it for free. Most finance programs charge six figures to teach it worse.

His name is Doug Costa. Twenty-three years as a math professor at the University of Virginia. Eighteen years as head of quantitative research at Susquehanna International Group - one of the largest market makers on the planet.

The entire derivatives market - trillions of dollars moving every day - runs on a single idea. It is called no arbitrage. If you can build a trade that guarantees risk-free profit, the market has made a mistake. If you cannot, then there is only one mathematically correct price for every option. One. Not approximately. Exactly.

That constraint alone produces Black-Scholes. Binomial trees. Every pricing model you have ever heard of. All of them are just consequences of one logical rule.

Most people learn this backwards. They memorize the formula in a textbook. They plug numbers into a calculator. They pass the exam. And they never understand why the formula works - or why no other formula is possible.

Costa does it the other way. He starts with the reasoning. He builds the logic from zero. No formulas first. No shortcuts. Just a mathematician walking you through the idea until the pricing framework assembles itself in front of you.

Finance courses charge thousands to teach this. Quant prep programs sell it as premium content. Wall Street interview prep books dedicate entire chapters to it and still explain it worse than one lecture from a man who spent his career inside the math.

The lecture is free. The formula has been public for decades. The intuition behind it is what separates people who use the equation from people who understand it.

The understanding is the entire edge.

[Striple @ogstriplle]

In December 2007 the first cracks appeared in the bond market. By September 2008 the entire global financial system was on the edge of collapse. Lehman Brothers gone. Bear Stearns gone. AIG hours from bankruptcy.

At the center of it all - three letters that most people had never heard before. CDS. CDO. Instruments designed to distribute risk. Instead they concentrated it, hid it, and multiplied it until the whole structure caved in.

Bonds that were supposed to be safe. Ratings that were supposed to mean something. Models that were supposed to account for everything. None of it worked the way it was advertised.

This lecture is taught by a quant educator at Susquehanna International Group. Doug Costa spent twenty-three years as a professor of mathematics at the University of Virginia. Then he left academia and led SIG's quantitative research division for eighteen years. He built the models. He priced the derivatives. He was inside the machine before, during, and after it broke.

In this video he sits down and takes the entire crisis apart. Piece by piece. How bonds are actually priced. What a credit default swap really is. How CDOs were structured, tranched, stamped with triple-A ratings — and why those ratings meant nothing.

He doesn't start with the panic. He starts with the math. And by the end you understand not just what happened - but why it was inevitable.

No drama. No hindsight. No shortcuts. Just a mathematician explaining the collapse from the inside of the equation.
