2021/08/24

Most people know the seismograph, those ultrasensitive instruments that record every small shift in the Earth’s crust.But did you know that the very latest method for measuring earthquakes involves fiber optic cables that carry internet data around the world?Stanford geophysicist Biondo Biondi says that the waves of energy sent forth by an earthquake cause fiber optic cables to stretch and contract ever so slightly. Using precise mathematical algorithms, experts like Biondi can measure earthquake

Anyone who’s ever made weekend plans based on the weather forecast knows that prediction – about anything – is a tough business. But predictive models are increasingly used to make life-changing decisions everywhere from health and finance to justice and national elections. As the consequences have grown, so has the weight of uncertainty, says today’s guest, mathematician and statistician Emmanuel Candès. Candès knows this paradigm all too well. He is an expert in identifying flaws in today’s highly

2021/07/19

Electronics are everywhere these days, so much so that often we don't even register that we are using them. The use of electronics will only grow over time as engineers solve societal challenges through increased connectivity, faster computation, new high-tech gadgets, and energy sustainability. Against that backdrop, electrical engineers like Stanford’s Srabanti Chowdhury have been searching for new semiconductors that can expand the application space beyond the ubiquitous silicon. Among the

2021/06/26

Engineer Irene Lo studies markets, but not traditional marketplaces based in cash.Instead, she studies markets for goods/resources that place a high value on social goods like diversity, fairness and equity.Thus, Lo came to help San Francisco create an algorithm to assign kids more fairly to public schools across geographic, social, racial and economic boundaries. As it turns out, math is just the first step. The most challenging part was getting families to trust in the system, begetting a

Nate Persily is a professor at Stanford Law School and an expert in election law.He sees the most recent presidential election as a fundamental change in the way Americans vote. For the first time ever, the majority of voters cast their ballot by mail, rather than at a polling place. It “was an earthquake,” Persily says, speaking metaphorically about the 2020 election’s profound implications for future elections.But not all agree it was a success.

Sam Wineburg, a research psychologist at Stanford’s Graduate School of Education, recently conducted a nationwide study of the fact-checking skills of thousands of American high school students.He didn’t go about it with a survey asking the kids to self-report their own behaviors. Instead, he devised a live experiment that charged the 3,000 students in the study to determine the veracity of a now-famous bit of fake news from the 2016 election.

Many have now become familiar with the term herd immunity, an idea few outside the infectious disease community knew just a few short months ago.It’s an elusive concept to comprehend, and harder still to achieve, but Stanford epidemiologist Dr. Julie Parsonnet says it’s important to understand just what herd immunity does – and doesn’t – mean for today’s pandemic.Broadly speaking, herd immunity is reached when enough people have either recovered from or have been fully vaccinated against an

Slowly but surely, the highly centralized, industrial electric grid that supplies power to the vast majority of American homes and business is changing.Our existing system of massive power plants and huge networks of high-voltage wires is giving way to a much leaner, decentralized system of small-scale power generation on a more personal, neighborhood- or residence-level scale.In other words, we’re going from an “infrastructure-centric” model to a “human-centric” one, says grid expert Ram Rajagopal

The world’s once linear — take it, treat it, use it, dispose it — model of freshwater usage is changing fast.Despite two-thirds of Earth being covered in water, just 2.5% of it is fit for human consumption. And that share is dwindling by the day, says civil and environmental engineer and expert in water treatment and distribution systems Meagan Mauter. With a rapidly increasing population and climate change disrupting traditional weather and distribution patterns, access to freshwater is headed for,

As the world moves to more efficient and cleaner energy solutions, there is a growing divide between the clean-energy haves and have-nots, says Anthony Kinslow II, PhD, a lecturer in civil and environmental engineering. Too often the divide falls along racial and socio-economic lines, as minority and low-income communities do not benefit from clean energy to the degree that whiter and wealthier communities do.The problem is founded in history and in the federal government’s askew system of financing

Words are a window into human psychology, society, and culture, says Stanford linguist and computer scientist Dan Jurafsky. The words we choose reveal what we think, how we feel and even what our biases are. And, more and more, computers are being trained to comprehend those words, a fact easily apparent in voice-recognition apps like Siri, Alexa and Cortana.Jurafsky says that his field, known as natural language processing (NLP), is now in the midst of a shift from simply trying to understanding
