Imagine a highly reliable cancer test. It detects 95% of a certain type of cancer, and has a "false positive" rate of only 1%. This test is used on a population in which this type of cancer occurs in 0.5%. One day your doctor tells you that you have tested positive. What is the chance that you are actually sick? Surprisingly, it is only about 32 percent!
Isaac Newton was a complex man. Every student learns of (but few master) the laws bearing his name that govern the motion of objects from bullets to planets. Many know that the same great mind invented calculus along the way toward his Principia Mathematica.
One part (but only one part) of the decline in science in the US is the growing minority of citizens who semiautomatically adopt positions antagonistic to those of the scientific consensus, regardless of the issue. The "scientific community" is not a monolith, and skepticism and dissent are essential to the process of science.
America's public schools are in trouble, and there are few who would disagree. But despite billions of dollars spent in "reform" efforts, little real progress seems to be occuring. No Child Left Behind (NCLB) was a step (or a misstep, perhaps) toward greater accountability by schools for student achievement.
Meet Flavia de Luce. You are going to like her. It is 1950 and Flavia, a very precocious eleven year old, lives in a small village in England in a deteriorating grand mansion with her father and two older sisters. Her passion is chemistry, which she has learned on her own by reading a textbook owned by her deceased mother and practiced in a laboratory inherited from her uncle.
When I saw this new book on the subject of evolution, I thought it would probably be one side or the other of the very tired evolution/creationism-"intelligent" design debate. I was delighted to find instead a very smart discussion of the status of our understanding of the origins of life, how life has changed over the millennia, and how we have learned about those things. Mr.
Having just returned from the Gordon Research Conference on Chemical Education Research and Practice, I can attest to the central role that statistics plays in chemical education.
The shortage of well-trained science teachers is widely recognized, but the solution to the problem requires first an appreciation of its causes. This little book, which is available free online, addresses the tangible and intangible reasons why fewer talented people choose science teaching as a career or choose not to stay in teaching.
Jan Hendrik Schön published some of the most exciting and ground-breaking physics of the past decade. He published it in the most prestigious specialty journals such as Physical Review Letters, Nature and Science. He won several important prizes and was being nominated for more of them when a problem came to light. The problem was that Schön had no data to substantiate his discoveries .
What good is music? Oliver Sacks (author of The Man Who Mistook his Wife for a Hat, The Island of the Colorblind, and especially - for chemists - Uncle Tungsten) concludes in the Preface to Musicophilia that there is no apparent evolutionary advantage associated with human appreciation for certain combinations of sounds and rhythm.
