Stanford coronavirus research: Did politically motivated scientists hype their speedy study?
SAN JOSE, Calif. — In the race to combat the COVID-19 pandemic, the world’s scientists have embraced a radically new method of disseminating information about their research, offering it quickly and without filters in the effort to understand and control this deadly disease.But their new communication model is striking at the heart of scientific integrity, publicizing research that has been corrupted by speed, sloppiness and opacity. And now the academic world is being roiled by a question for which millions of lives hang in the balance: Is the public being well-served by the fast and free flo...

35% of people infected with COVID-19 show no symptoms, according to CDC's 'best estimate'
About a third of people infected with coronavirus in the U.S. are asymptomatic, according to newly released guidance from the Centers for Disease Control and Prevention.The CDC and the Office of the Assistant Secretary for Preparedness and Response have developed five different planning scenarios to help public health officials making coronavirus decisions based on mathematical modeling.To determine each scenario, the CDC looks at “measures of viral transmissibility, disease severity and pre-symptomatic and asymptomatic disease transmission.”An “asymptomatic case” means that an individual infe...

Mac Engel: Coronavirus has forced us to confront our worst fears: Teaching math to a 5th grader
Forget speaking in public or death, our greatest fear should be, “Help your fifth-grade child with their math homework.”Before COVID-19 we all expressed our deepest love and respect for the teachers of the world who go through the glass-smashing process of instructing our children. After COVID-19 we will actually mean it.Sitting with my daughter for even two minutes to go over her math homework, it all comes back.The ability to complete the fifth-grade problems is not what returns. What returns are the stomach pains of fear, dread, inadequacy and stupidity.The powers of 10. Fractions. Long div...

Mathematical models help predict the trajectory of the coronavirus outbreak. But can they be believed?
SEATTLE — As Washington Gov. Jay Inslee weighs the economic cost of coronavirus closures against the health risks to Washington state residents, high on his daily reading list are the latest results from a suite of computer models.Some are from top universities around the world. Others are homegrown. All are attempting to peer into an uncertain future and evaluate possible paths forward through a pandemic unlike any other in modern times.From state houses to the White House and city council Zoom meetings nationwide, mathematical models have rarely been so influential — or so hotly debated.Pund...

You can learn math and English online, but how about pottery? Hands-on education challenged after COVID-19 closes schools
CHICAGO — Veronika Pesovic’s sponge cake looked and tasted fine, but she knew something was off. It was denser than it should have been, and she wasn’t sure how it ended up that way. Were the egg whites whipped properly? Was the oven too hot, or not hot enough?Had the aspiring pastry chef been in her classroom at the College of Lake County, where she is enrolled in a patisserie course, she could have asked her teacher on the spot. But the campus is closed and Pesovic is confined to her Grayslake home, continuing her education in her own kitchen.“A big part of baking is how things look and how ...
Marcos Breton: Luke Walton is teaching his kids math at home. He can't wait to count to five on the court.
SACRAMENTO, Calif. — It was good to talk to Luke Walton by phone on Thursday. I needed it and maybe he needed it too. The first-year Kings coach is a kindergarten math teacher these days as he shelters in place with his family in Sacramento.Last summer, the hope was that Walton would be coaching the Kings in the playoffs this week. You might recall that the Kings haven’t made the playoffs since the Spring of 2006 — 14 long, dismal, spirit-crushing seasons ago.Instead, six weeks on from COVID-19 causing the suspension of the NBA season on March 11, Walton is coming up with math equations for hi...

Kings coach Luke Walton teaches math, watches 'Tiger King' during coronavirus shutdown
SACRAMENTO, Calif. — Kings coach Luke Walton has watched a lot of game film while hunkered down in his home in the six weeks since the NBA suspended its season due to the coronavirus crisis, but that’s not all he’s watching.During a conference call with reporters Wednesday, Walton offered his thoughts on social distancing, homeschooling, the threat of COVID-19 and two documentary series that are keeping America entertained: ESPN’s “The Last Dance” and Netflix’s “Tiger King: Murder, Mayhem and Madness.”“I have watched every episode of ‘Tiger King,’” Walton said. “I had no idea what it was about...

Small pharmacies are under financial pressure just when they're needed most: 'The math doesn't work'
PHILADELPHIA — Richard Ost has run Philadelphia Pharmacy in the city’s Kensington neighborhood since 1983. It’s the one you can’t miss for the bright blue mural that washes over the building. In response to the coronavirus pandemic, he made some changes: He engaged more drivers to deliver prescriptions, bought masks for his employees, and hired another person to keep watch over the entryway and provide masks to customers without them.People still need their prescriptions, and Ost is delivering them, for free, at a clip of 150 customers a day, up from 20 to 30 deliveries before. But when he loo...

MCO is absolutely necessary: Mathematics of Covid-19
COMMENT | We are right in the middle of the Covid-19 pandemic. As mathematicians, we are concerned about two major issues: (1) What is the prognosis for the current Covid-19?; and (2) How to stop a potential second wave?During the 2009 H1N1 pandemic, we were equally worried about the possibility of a second wave (Koh and Teh, 2011) but fortunately, that did not happen.The extension of the movement control order (MCO) by another two weeks to April 14, 2020, is absolutely necessary to prevent a potential immediate second wave.So, we tried to use some simple calculus to demonstrate how mathematic...
Coronavirus math shows importance of social distancing — and consequences of not doing it
PHILADELPHIA — If you still doubt the crucial importance of avoiding other people, or if you think Philadelphia’s “stay at home” order is excessive, consider this:Without the lockdown in Wuhan, China, where the pandemic started, there would have been 44,214 cases in other Chinese cities through February — instead of the actual number of 27,956, according to a new study led by University of Pennsylvania economist Hanming Fang.“Social distancing and, if an epicenter can be identified, as was the case for the city of Wuhan in China, a lockdown can play crucial roles in ‘flattening’ the daily infe...
