He also knows how to tell stories. The first chapter contrasts the biographies of two of DNA’s discoverers, Mendel and the less well-known, Johannes Friedrich Miescher, who because he studied fish slime had to work in very cold conditions so that his material would not deteriorate before he could examine it. And who knew that Mendel joined a monastery so he could secure a university education? His passion for raising peas taught us so much about human inheritance.
This book tackles and at least partially answers many of life’s great questions including: Why did it take eons for life to become complex? What is our most ancient DNA? Why do humans have no more DNA than so many smaller, less complex creatures? Why did we almost become extinct? Why did we break away from monkeys? Is the impulse for art conveyed by our DNA? Why are identical twins not identical? Read more »
Groundhog’s Day has come and gone, but the shadow of its promise of longer, warmer days lingers! For preschool science in February, we explored the world of light, reflection, and shadow. These activities are meant to promote lively discussions between children and their adult partners, which builds vocabulary and knowledge of the world.
As any parent knows, young children are curious about the world. At the library, we explore a range of topics during Preschool Science and Math. When the weather turns cold, I turn to one of my favorite themes for preschool science: Animals in Winter. Here are some of the activities we did in December!
Tonight if you are lucky and the sky doesn't cloud up, you will be able to observe one of astronomy’s rare celestial events, the transit of Venus. But be careful, and don't look directly at the sun without using safe viewing glasses or lenses. If you don't own those, you can attend one of the free events listed below. If you miss tonight's transit, alas, you won’t catch another in your lifetime because the next one won’t occur until 2117.
I’ve been reading about the transit of Venus and how an earlier one in the 18th century really expanded our knowledge of the solar system. It also was the earliest example of a large and cooperative international scientific expedition.
We have two new books that report on this scientific quest. Andrea Wulf's Chasing Venus: the Race to Measure the Heavensreports on the work and incredible adventures that were undertaken by scientists worldwide in trying to observe and make measurements for the transit that occurred on June 6, 1761. In an age when it took several months for a letter to cross the oceans and a few more months for a response, a scientist in England organized this great scientific undertaking. In remote corners of the world, scientists from Britain, Russia, India, Germany, the Read more »
Daniel Kahneman’s Thinking Fast and Slow is still a bestseller and heavily in-demand at the library, after receiving lots of publicity late last year. This exploration of intuitive vs. deliberate thinking makes fascinating points about what motivates decisions both personal and business-related. It’s top notch popular psychology, a genre I really love for the way it forces you to examine actions and thoughts that seem simply natural or logical. Here are a few other great examples.
Another newish title that’s making a splash is Quiet: The Power of Introverts in a World that Can’t Stop Talking. The subtitle pretty much sums it up. It explores the differences between introverts and extroverts and makes the case for the values of introversion, which are often ignored in a society that holds extroversion to be the ideal.
Malcolm Gladwell is a giant in this area. One of his great books is Blink, which, like Kahneman’s, uncovers what’s really going on in our heads when we make decisions, illuminating everything from how prejudice works to why marriages fail.
Oliver Saks, a neurologist, also has several great books. The Man Who Mistook His Wife for a Hat, for example, demonstrates how complex the brain is by showing how weirdly things can go wrong. It’s more neuroscience than psychology, perhaps, but seeing how knocking out one little area can cause hallucinations or destroy one very limited function, is fascinating.
Steven Pinker recently wrote a book (The Better Angels of Our Nature) proposing that humans are becoming less violent, but I really like his 2003 book The Blank Slate. It touches on the emerging field of evolutionary psychology, arguing that people aren’t born with completely plastic minds, but that we all have certain (possibly very powerful) innate tendencies and capabilities.
In The Psychopath Test, Jon Ronson teaches us how to spot a psychopath, and finds that, far from being universally confined to mental hospitals, they are all among us—especially, it seems, in the world of business.
The Believing Brain takes a critical look at how belief—not just religious, but in general—is formed and reinforced. Michael Shermer argues that it is natural, but that we need to temper such instincts to see the world clearly.
Snoop has a fun (and kind of unsettling premise): the things we surround ourselves with and the way we arrange them speak volumes about who we are. Our personalities leak through in what seem like insignificant places.
Browsing the new science books, I came across The Sun's Heartbeat. I picked it up expecting a rather dry collection of facts and was immediately engaged by a chapter titled "The Wild Science of the Bearded Men."
Not only can Bob Berman write but he also has that gift shared by all the best science writers: the ability to translate complex scientific terms into language that anyone can understand.
This book provides a compelling overview of several thousand years of sun research including the great sunspot controversy of the 17th century. The invention of the telescope in 1608 spurned a race to discover facts about the sun. Johannes Fabricius and his father discovered little spots on the sun and excitedly watched them for days until they burnt out their retinal cells. An English astronomer who had voyaged to Roanoke with the English explorers also began recording sunspots. And Galileo himself entered the fray. In fact, Galileo engaged in a decades-long fight with the German professor Christoph Scheiner over sunspots. Over who discovered them first--in fact, neither had, over whether the sun has an atmosphere, and many other topics. Read more »
While most books about the Arctic or Antarctic focus on just one thing--the indomitable quest to reach one of the poles--this book has a much broader canvas--it covers the equally arduous work of making new scientific discoveries during the age of great polar exploration.
This broader canvas allows the reader to learn about biological, geological, and meteorological phenomena but also about the cost of empire. England sponsored many of these expeditions while this country held political dominion over one quarter of the world. And as the twentieth century dawned, political power was changing rapidly. Britain had lost face in the Boer Wars in Africa and needed heroism and success to bolster its image abroad and its people's faith in the government and military as Germany, France, and the United States were becoming arch competitors.
But the book is mostly about science and adventure under the most brutal conditions. At one point Scott and Shackleton dock near an ice floe and decide it's time to use a hot-air balloon to get a better view of the landscape ahead. In this totally unpeopled land, Scott rides up into the air and views the vast white expanse. For most of us, such a view would provoke sheer terror. And Scott himself was a little nervous in the little bamboo basket. I kept thinking, what if he falls out. Read more »
Everything is not what it seems. I guess I watch too much tv. I've always been under the impression that forensic investigations and death investigations were done in a highly scientific and professional manner. As it turns out, the reality is that throughout most of America the position of Coroner is an elected position. This means that the person doing the investigation could have little to no experience at all which could then lead to a Read more »
It seems common knowledge that riding your bike to work is a low carbon activity. What you might not know if that if you fuel your bike ride with air-freighted off season asparagus, then your carbon footprint increases dramatically and you'd be better off commuting buy Hummer. The art and science of taking into account many aspects of what constitutes a carbon footprint has often been ignored. Read more »
OK, who can resist a title like How I Killed Pluto...? It promises and then delivers a light, interesting take on the Pluto demotion from one of the nine big ones to a dwarf planet at the edge of our solar system. "My very excellent mother just served us nine pizzas." Do you remember that line from science class in grade school? The words helped us remember the planets and their order in the solar system: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, Pluto. Alas, now mother is just serving us nine___?
