ScienceNOW. How Many Dimensions Does the Universe Really Have?

scienceNOW

An engineer, a mathematician and a physicist walk into a universe. How many dimensions do they find? The engineer whips out a protractor and straightedge. That’s...

Michael Osterholm, his face a pink-cheeked scowl, looked out across the table, beyond the packed room at the New York Academy of Sciences, and out through the windows.

Flu Fighters

The New York Academy of Sciences is housed on the fortieth floor of 7 World Trade Center, and their endless bank of windows affords a staggering view of Manhattan, Brooklyn, and New Jersey. One reason that its view is so magnificent is that there’s a huge gap in the skyline–and a huge gouge in the ground–where the Twin Towers once stood. Osterholm had come here from Minnesota, where he runs a research center for infections diseases and terrorism, to talk Thursday night about the threat of a new kind of flu sitting in labs in the Netherlands and Wisconsin. In nature, it’s a flu that spreads easily between birds but doesn’t travel well from human to human. The Dutch and Wisconsin scientists had found ways to get this bird flu, known as H5N1, to move between ferrets.

This argument positively enraged Osterholm. Science in Seconds. Scirus - for scientific information. Einstein for Everyone. Einstein for Everyone Nullarbor Press 2007revisions 2008, 2010, 2011, 2012, 2013 Copyright 2007, 2008, 2010, 2011, 2012, 2013 John D.

Preface For over a decade I have taught an introductory, undergraduate class, "Einstein for Everyone," at the University of Pittsburgh to anyone interested enough to walk through door. With each new offering of the course, I had the chance to find out what content worked and which of my ever so clever pedagogical inventions were failures.

At the same time, my lecture notes have evolved. This text owes a lot to many. I i i. Real-Life Chemistry Vol 3 - Physics Vol 1. Einstein’s Secret to Amazing Problem Solving (and 10 Specific Ways You Can Use It) Einstein is quoted as having said that if he had one hour to save the world he would spend fifty-five minutes defining the problem and only five minutes finding the solution.

This quote does illustrate an important point: before jumping right into solving a problem, we should step back and invest time and effort to improve our understanding of it. Here are 10 strategies you can use to see problems from many different perspectives and master what is the most important step in problem solving: clearly defining the problem in the first place! The Problem Is To Know What the Problem Is The definition of the problem will be the focal point of all your problem-solving efforts.
