Math 2021: The ‘Unsolved Riemann Hypothesis’ Explained (Quanta Video)
The Riemann hypothesis is the most notorious unsolved problem in all of mathematics. Ever since it was first proposed by Bernhard Riemann in 1859, the conjecture has maintained the status of the “Holy Grail” of mathematics. In fact, the person who solves it will win a $1 million prize from the Clay Institute of Mathematics. So, what is the Riemann hypothesis? Why is it so important? What can it tell us about the chaotic universe of prime numbers? And why is its proof so elusive? Alex Kontorovich, professor of mathematics at Rutgers University, breaks it all down in this comprehensive explainer.
In mathematics, the Riemann hypothesis is a conjecture that the Riemann zeta function has its zeros only at the negative even integers and complex numbers with real part. Many consider it to be the most important unsolved problem in pure mathematics.

Investigations: Chinese Telecomunications Giant Huawei – High Tech or Spy?
Telecommunications giant Huawei is said to be one of the most powerful companies in China. But Huawei has been accused of systematic espionage, and some Western governments doubt whether the company is truly independent of the Chinese government.
This documentary investigates concerns about Huawei and internet security. The company is a major player in the manufacture of smartphones, and enjoys a technological lead in the development of the super-fast 5G broadband network worldwide. But the US and some other Western countries suspect that Huawei works closely with the Chinese government on espionage and sabotage operations.
Has Huawei becomne a pawn in the trade war between the US and China? The arrest of Huawei chief financial officer Meng Wanzhou in Canada in 2018 — at the request of US authorities — marked the climax of the conflict between Huawei and Washington. Some European countries also have concerns about the company.
Does Huawei really have close ties to the Chinese government? And what are the benefits and risks for those foreign clients who choose to work with this 5G giant?
Analysis: ‘Is Walmart The Future Of Health Care?’
Walmart, America’s largest grocer, launched a primary care clinic called Walmart Health, in September 2019. Analysts say the big box retailer faces several hurdles in its quest to scale up nationally with a roster of highly paid doctors and dentists. But with more than 35 million people uninsured as of 2019, and millions more with high deductible health plans, could Walmart Health’s low price point be the future of healthcare in America?
Deforestation: ‘Amazon Rainforest’ – Becoming A Savannah In 15 Yrs? (Video)
New research suggests that if the current rate of deforestation continues, the Amazon rainforest could transform into a savannah within 15 years. Do we have time to stop it?
The Amazon basin spans over 6 million square kilometers, and is home to one-fifth of the world’s land species. In addition, it supports the 30 million people who live and depend on the land as a source of food, medicine, and shelter. That’s not even including the key role it plays in regulating the regional AND global climate.
Trees absorb water through their roots and transport it to their leaves, where it’s released as vapor through small pores in a process called transpiration. As the water vapor rises and condenses, it forms rain clouds over the forest canopy. Basically, the rainforest is making its own weather. For example, one large tree can release 1,000 liters of water into the atmosphere in a single day.
The rainforest recycles this water up to six times before it moves out of the region, but as more trees are cut down, those that remain may not be able to recycle enough water to survive. Less trees means more sunlight will hit the forest floor, exposing the forest to higher temperatures. Since deforestation began accelerating in the 1970’s, 800,000 square kilometers of the Amazon have been lost. And over that same period, the average temperature of the basin has risen by 1 degree Celsius.
