Super quick computers and advanced mathematical formulas have taken over trading on the financial markets from human beings -algorithms- which seem to have a life of their own. The only ones who understand the system in any way are its architects, the algorithm developers. Haim Bodek is one such algo-developer. After finding some strange wrongdoings he set out on a personal crusade against this elusive system". The machinery behind our financial markets, consisting of mathematical models, data centers and miles and miles of fiber optic cables, is disguised by technological complexity and secrecy. The builders of this financial system are a new breed of Wall Street employees -quants- mathematicians and physicists who are responsible for a technological revolution. Haim Bodek is a quant; he specialized in artificial intelligence and worked for Goldman Sachs. He knows the system from the inside, he helped build it. Haim Bodek was invited to tell his story at the "Battle of the Quants" - a recurring event where quants discuss high-frequency trading, amongst other things. Bodek wrote an algorithm for trading machines that would generate guaranteed income - a money machine that weathered the financial meltdown of 2008. But then from one day to the next the algorithm stopped working.

This episode explores the nature of the greenhouse effect (discovered by Joseph Fourier and Svante Arrhenius), and the evidence demonstrating the existence of global warming from humanity's influence. Tyson begins by describing the long-term history of the planet Venus; based on readings from the Venera series of probes to the planet, the planet had once had an ocean and an atmosphere, but due to the release of carbon dioxide from volcanic eruptions, the runaway greenhouse effect on Venus caused the surface temperatures to increase and boiled away the oceans. Tyson then notes the delicate nature of the amount of carbon dioxide in the atmosphere can influence Earth's climate due to the greenhouse effect, and that levels of carbon dioxide have been increasing since the start of the 20th century. Evidence has shown this to be from mankind's consumption of oil, coal, and gas instead of from volcanic eruptions due to the isotopic signature of the carbon dioxide. The increase in carbon dioxide has led to an increase in temperatures, in turn leading to positive feedback loops of the melting polar ice caps and dethawing of the permafrost to increase carbon dioxide levels. Tyson then notes that humans have discovered means of harvesting solar power, such as Augustin Mouchot's solar-driven motor in the 19th century, and Frank Shuman's solar-based steam generator in the 1910's. Tyson points out that in both cases, the economics and ease of using cheap coal and oil caused these inventions to be overlooked at the time. Today, solar and wind-power systems would be able to collect enough solar energy from the sun easily. Tyson then compares the motivation for switching to these cleaner forms of energy to the efforts of the Space race and emphasizes that it is not too late for humanity to correct its course.

An unsettling yet visually fascinating documentary presenting the history of nuclear weapons development and testing between 1945 until 1963. Narrated by William Shatner, features extremely rare film segments from top secret government archives and startling footage of nuclear bomb tests conducted by Great Britain and China, plus the largest atomic explosion ever created by Russia, and de-classified U.S. footage released to the public as recent as May, 2006. Whether being exploded under the ocean, suspended by a balloon, shot from a cannon or even detonated in space, these weapons are capable of devastating destruction - the quality of these images is as startling as are remarkable.

This is the story of Gerald Cotten and the many people who ended up with empty bank accounts after investing in his Bitcoin cryptocurrency exchange, QuadrigaCX. What does a crypto exchange do? The movie explains it concisely and it almost makes sense: A guy like Cotten takes an investment, converts it to Bitcoin and trades it in hopes of turning a profit, kind of like a stock day trader does. Cotten ’s described as a nerdy guy who felt like an outcast, but found a community of like-minded types in the cryptocurrency world.
Cotten was in India when he got sick and unexpectedly died; he was 30. At the time, QuadrigaCX was Canada’s biggest crypto exchange, holding north of $200 million. But nobody could access the keys and passwords to the company’s accounts and, against conventional wisdom, the company had no safeguards to stop such a thing from happening. Everyone who invested their money was left grasping at empty air. Internet forums foster ideas such as Cotten faked his death and took the money. The journalists and forensic accountants who lend the voice of reason, explores the oddities in the Cotten narrative, ruling out some of the crazier stuff in a quest for the truth.

Millions know their voices, but no one knows their names. In his compelling film, award-winning director Morgan Neville shines a spotlight on the untold true story of the backup singers behind some of the greatest musical legends of the 21st century.
Triumphant and heartbreaking in equal measure, the documentary is both a tribute to the unsung voices who brought shape and style to popular music and a reflection on the conflicts, sacrifices and rewards of a career spent harmonizing with others. These gifted artists span a range of styles, genres and eras of popular music, but each has a uniquely fascinating and personal story to share of life spent in the shadows of superstardom.
Along with rare archival footage and a peerless soundtrack, 20 Feet from Stardom boasts intimate interviews with Bruce Springsteen, Stevie Wonder, Mick Jagger and Sting to name just a few. However, these world-famous figures take a backseat to the diverse array of backup singers whose lives and stories take center stage in the film.
