# The Conversation: How to flatten the curve of coronavirus, a mathematician explains

The Conversation: How to flatten the curve of coronavirus, a mathematician explains. “This general concept of slowing the virus’s spread has been termed “flattening the curve” by epidemiologists – experts who study how often diseases occur in different populations, and why. The term has become widespread on social media as the public is encouraged to practise ‘social distancing’. But how does social distancing help to flatten the curve?

# Wolfram Blog: 15 Ways Wolfram|Alpha Can Help with Your Classes

Wolfram Blog: 15 Ways Wolfram|Alpha Can Help with Your Classes. “Thinking back on those late-night study sessions, I would have saved a lot of time if I had properly used Wolfram|Alpha as a study tool. Because I was a biology major, many of the areas in which I most frequently sought information were related to scientific fields such as chemistry, but Wolfram|Alpha can be a valuable resource in so many more areas. Here are 15 applications of Wolfram|Alpha in topics beyond mathematics. I hope you will find these to be useful both inside and outside the classroom!”

# University of Sydney: How a first edition of Principia with Isaac Newton’s notes got to Sydney

New-to-me, from the University of Sydney: How a first edition of Principia with Isaac Newton’s notes got to Sydney. “While the original print run is estimated at between 250 and 400 copies, there are only 189 surviving first editions in the world and only four with annotations by the English mathematician himself. Of these four copies, the Sydney copy of Principia is the only one in the Southern Hemisphere and is held in the Rare Books & Special Collections at the University of Sydney library…. The University of Sydney copy of Principia has been digitised and is available online alongside other digital resources via the University’s digital collection.”

Worcester Polytechnic Institute: Helping to Make Math “Graspable,” WPI Researchers Guide Design of Algebra Tool for Students and Teachers. “Researchers at Worcester Polytechnic Institute (WPI) have received a $185,085 subcontract for the second phase of design development and testing of Graspable Math, a digital platform that helps students learn algebra…. Students have traditionally worked algebraic equations by making notations on paper, but Graspable Math puts algebra onto tablet and laptop screens. Students click on or swipe numbers and symbols to solve equations and get instantaneous feedback on their actions, while teachers can monitor their work.”
