Is Python The New Basic? ("Python For Kids")

My first computer language was PL/1, but soon after I learned, among other languages, Basic, and I really liked Basic and I still do. Basic is linear, and I think in linear constructs when I do any kind of computer program. This is probably, in part, because user interfaces are the last thing I want to deal with. I want a series of numbers to be treated in a certain way, or a set of formulas to generate a database. The most non-linear I tend to get is multidimensional arrays, and that’s still linear.

Python is potentially, and in practice, very different, and is essentially used as an object-oriented language. Yet at the same time it can be used in any other way, to reproduce pretty much any sort of programming paradigm. People thought of Basic as not very readable, but in fact, it was in its more advanced form if you programmed right. Python is said to enforce readability, if by readability we mean enforced indentation. People are still free to ruin readability in a number of other ways. But most importantly, Python holds a very important feature in common with Basic: It is interpreted. In other words, at any point in time while you are writing your Python program, you can “run” it and see how it is going.

The biggest difference between a language like Basic even at its high water mark some years ago, and Python is that Phython has plenty of modules for use do do all sorts of cool things. I’m not sure if the Python library is the biggest and vastest and most amazingest of all, but it probably is. So, if you are going to pick a programming language with paradigmatic flexibility, reasonable readability, and a powerful and diverse library of functionality, the Python is probably the way to go.

And therefore, you should teach it to your children. And this is where Python for Kids: A Playful Introduction to Programming by Jason Briggs comes in.

Officially…

Python for Kids is a lighthearted introduction to the Python programming language, full of fun examples and color illustrations. Jason Briggs begins with the basics of how to install Python and write simple commands. In bite-sized chapters, he explains essential programming concepts. And by the end of the book, kids have built simple games and created cool drawings with Python’s graphics library, Turtle. Each chapter closes with offbeat exercises that challenge the reader to put their newly acquired knowledge to the test.

The first thing that you need to know is this: If your computer has any sort of development environment set up on it, the instructions for installing Python provided in this book may be problematic or at least slightly difficult. I recommend using this book an an installation that is virtualized or simply a different computer than you otherwise develop on, not just so that your kid does not accidentally delete, or worse, alter and publish, your pet projects. Part of the process of modern programming, after all, is learning about the development environment.

There are a handful of good “learn to program in python” books out there and this one is similar; it is hard to know at which point someone using the book will pass from “Oh, I see, that’s easy” to “Huh?” which usually occurs a chapter or two after the person stopped paying attention to details. Python for Kids: A Playful Introduction to Programming does a good job of avoiding this problem by including a complete and rather extensive project, a game called the “Mr Sick Man Game” (which should be read “Mr. Stick-man game” and not “Mr. Stick… Mangame!”) There are plenty of other projects and individual programs that the book guides the reader through prior to the mangum stick opus. The book uses the “Turtle” module, based on LOGO, for much of this work. as well as the tkinter TH GUI toolkit interface. So if you don’t want your children near those modules, look for a different book, just in case you are involved in some sort of emacs-vim style code war.

Python for Kids is not available at this time but will be shipped in December, so this is a viable stocking stuffer option.

A Book about Taung and "the Hobbit"

The Fossil Chronicles: How Two Controversial Discoveries Changed Our View of Human Evolution is by a scientist Dean Falk, who has contributed significantly to the study of evolution of the human brain, and who has been directly involved in some of the more interesting controversies in human evolution.

Back when I was a graduate student I was assigned by my advisor a set of literature to absorb and comment on. The mix of published and soon to be published papers included a series of papers written by Ralph Holloway and Dean Falk. These represented a fight over the interpretation of early hominid brains as studied through endocasts. Endocasts are fossilized casts of the inside of an animal’s brain case or the artificially produced version made of casting material poured into a skull. Either way, you get a roundish blob that resembles the exterior of the original brain. Endocasts are of limited value, as layers of tissue in a living mammal separate the brain from the skull, attenuating detail. As Falk point out in her book, endocasts are a rather “surficial” view of a brain, but are not without their uses.

Fossil endocasts are compared to endocasts made from the skulls of “living” primates and humans, which in turn are understood via Continue reading A Book about Taung and "the Hobbit"

Godless Gift Idea!

Santa wants you to have this book!
Atheist Voices of Minnesota (which comes in a print version and a Kindle version) is a collection of individual journeys to atheism. All the authors are Minnesotan (natural born, former, or immigrant to the North Star State). While some of the authors are professional writers or high profile bloggers, most are regular people with interesting stories to tell. The essays are selected from a much larger group of submissions, the works are carefully edited, and organized into general categories. The Minnesota connection itself is great for Minnesotans, but really not all that important for general readers; this is simply a collection of stories that help show how Atheism is not a scary cult including baby eaters and hedonistic Satan worshipers. Mostly. And for this reason, it is a great gift for you to give to your family, which probably includes a mixture of believers and non-believers and not-sure-what-to-believers. You can give it to your mom or to Uncle Joe as a gift from you, you can put it in someone’s stocking anonymously, or you can even make it the prize in some Christmas Celebration activity your family celebrates such as the Three-Legged Elf Race or the Inter-Family Scrabble Tournament.

The book has done reasonably well and the initial printing and publishing costs are now paid for, so all the profits from this point forward go to help support Minnesota Atheists, which brings you, among other things, Minnesota Atheists Talk Radio, which is one of the few regular (weekly) shows based in a live radio setting and produced as a podcast that deals directly with issues of interest to Atheists. Many of the shows are about religion, atheism, and related topics, but a good number are about science, science education, and science outreach.

So please consider giving Atheist Voices of Minnesota: an Anthology of Personal Stories to your friends, families, and loved ones for Christmas, Winter Solstice, Hanukah, or Kwanza this year!

The Authors include Norman Barrett Wiik, Elizabeth Becker, Kenneth Bellew, Ryan Benson, August Berkshire, Donald L. Boese, Ryan Bolin, Jill Carlson, Justin M. Chase, Greta Christina, Linda Davis, Andrew Downs, Shannon Drury, Anthony Faust, Paul Gramstad, Mike Haubrich, Kori Hennessy, Peter N. Holste, Michelle M. Huber, Eric Jayne, George Kane, Greg Laden, Bill Lehto, M. A. Melby, PZ Myers, Robin Raianiemi, Rohit Ravindran, Jason Schoenack, Kim Socha, Chris Stedman, Elizabeth Stiras, Todd N.

Just In Time for The Hobbit: The Science of Middle Earth

Just a quick note, review to come later. Henry Gee has produced a Second Edition of his book The Science of Middle-Earth: Explaining The Science Behind The Greatest Fantasy Epic Ever Told!, which will be released on December 14th as a Kindle eBook.

There are two things to know about this. First, the Second Edition is revised enough to want to get it even if you have the first edition. Second, if you are not familiar with the book, it may be a bit different than you expect. It is not a book about the science IN Tolkein’s books as much as it is a scientifically oriented investigation of Tolken, the world he created, and the relationship between that made up world and the real world that provided the context for the created universe. Gee is a scholar of Science Fiction literature and his prowess in this field is well demonstrated by his cogent and deep analysis of Tolkien. The Science of Middle-Earth: Explaining The Science Behind The Greatest Fantasy Epic Ever Told! is a philology of the pertaining documents, an anthropology (both cultural and biological) of the languages of that world, and an historical investigation of origins. There is demographics and life history theory, geology, genetics, allometry, and some attention to the mechanics of locomotion of trees and flying things.

You will probably want to read this before you see The Hobbit.

I’ll let you know if I notice the book’s early availability.

You come from Cannibals

A man “lies crumpled on the sand … Behind him a dark trail leads back to the spot from which he has just been dragged. Looking closer, we notice something slightly odd about the figure crouching over the wounded man. His posture does not suggest a doctor attempting to staunch bleeding, or even to check heartbeat or pulse. Look a little closer still, and you may be inclined suddenly to reel back or to close your eyes. The man sprawled at such an odd angle beside the injured [man] has his face pressed against a gaping tear in [his] throat. He is drinking blood fresh from the wound…” Why? Well, to cure his epilepsy, of course. The date is 24 AD, the injured man is a gladiator, and the man drinking the blood must have bribed his way to the front of the line because he’s getting what a lot of other people in Ancient Rome routinely sought. A nice blood meal, for medicinal purposes, of course. Continue reading You come from Cannibals

DIY drinking tips, personal jet pack, custom fit earbuds, and a pocket theremin

… the perfect gaming chair, converting a Roomba into a security robot, removing a stripped screw with a rubber band, making a radio out of spare parts from your junk drawer, building your own lie detector machine, making a Steampunk Laptop, using the back of your monitor as a desktop, tricking out your bike, and making a ping pong table that will allow only YOU to win to matter how good your opponent may be.

Obviously, I’m talking about The Big Book of Hacks: 264 Amazing DIY Tech Projects, which is just now available, just in time for Christmas.

Pro gift giving tip: Bundle this book with a nice new soldering iron, or some other tool mentioned and used in the book.

I tried to give a good overview of the vast range of hacks presented in this book, but that is almost impossible. They are divided into categories: Geek Toys, Home Improvements, Gadget Upgrades, and Things That Go. The book starts out with some basics (such as how to solder) and then jumps right into beer brewing and drinking booze from a watermelon. One of the coolest things ins a mod for your toaster that lets it make special toast. Like, with a happy face, or a picture of Jesus, or whatever. There are a lot of hacks involving fire and minor explosions, or that involve propelling things great distances. I suppose one could argue that one learns a lot of physics and chemistry and stuff while working through these various DIY project ideas. Whatever. Just keep the first aid kit handy and make sure you know where your cell phone is. Hack #163 is a solar charger for your cell phone.

Did you know that there is such a thing as a “touchscreen overlay” that you can put on any screen to make it a touchscreen? DID YOU?

It goes on and on. I love this book. I’ll probably never do any of the things in it, but what is true of most porn is just as true of DIY porn.

Some of the proceeds of this book go to saving the cute baby animals from stuff.

Kurzweil: How to create a mind

How to Create a Mind: The Secret of Human Thought Revealed is Ray Kurzweil’s latest book. You may know of him as the author of The Singularity Is Near: When Humans Transcend Biology. Kurzweil is a “futurist” and has a reputation as being one of the greatest thinkers of our age, as well as being One of the greatest hucksters of the age, depending on whom you ask. In his new book…

Kurzweil presents a provocative exploration of the most important project in human-machine civilization—reverse engineering the brain to understand precisely how it works and using that knowledge to create even more intelligent machines.

Kurzweil discusses how the brain functions, how the mind emerges from the brain, and the implications of vastly increasing the powers of our intelligence in addressing the world’s problems. He thoughtfully examines emotional and moral intelligence and the origins of consciousness and envisions the radical possibilities of our merging with the intelligent technology we are creating.

Certain to be one of the most widely discussed and debated science books of the year, How to Create a Mind is sure to take its place alongside Kurzweil’s previous classics.

I think there are three key ideas in this book about which I have varying opinions. First, he presents a model of how the brain works. Second, he suggests that we can, in essence, reverse engineer the brain using computing technology. Third, he discusses the rate at which computing technology becomes more capable of doing such a thing, both qualitatively and quantitatively. He ties these idea together with reference to artificial intelligence theory.

Regarding the second point, I have no doubt that we will someday be able to produce a non-biological brain. Brains are physical entities that emerge with very little specification as to architecture, have incredibly dense circuitry that carries enough information for otherwise reasonable people to assert that its information storage capacity is infinite (which it is not, of course), and that involves interactivity among components that allows for some amazing things to happen. I think that when we get close to making a mechanical brain, we would probably want to set aside many of the ways in which actual brains function, in order to create a more effective computing solution, because the brain is a product of Natural Selection and is thus not necessarily all that well deigned. The trick will be sorting out that which is good design for mechanical implementation of human braininess from that which is not good design. Regarding the third point, the expansion of computational abilities, I’m sure the basic ideas Kurzweil lays out are reasonable but furturism about technology seems to run into the same problem over and over again: Somebody invents a qualitatively distinct way of doing something that totally changes the game, and after that, this new way of doing things quantitatively evolves. Predicting the qualitative shifts has been difficult.

My biggest problem with Kurzweil’s book is in relation to the first point, a theory about how the brain’s cortex works. He asserts that the cortex is a self organizing entity that responds to information, creating an ability to manage and recognize patterns. My problem with this is that Kurzweil seems to have not read Deacon’s work (such as The Symbolic Species: The Co-evolution of Language and the Brain and Incomplete Nature: How Mind Emerged from Matter. I’m not saying that Kurzweil is wrong in thinking of the cortex as self organizing in response to the challenges and inputs of pattern recognition. I’m simply saying that this property of the cortex, and of the human mind, has already been identified (mainly by Deacon) and that Kurzweil should sit down with Deacon and have a very long conversation before writing this book! (Well, ok, the next book.) I don’t think they’ve done that yet.

Newton and the Counterfeiter

The other side of the coin(age): Newton and the Counterfeiter

Did you know that Isaac Newton had two jobs? One, you know about: To figure out all that physics and math stuff so we could live for a while in a Newtonian world (later to be replaced by an Einsteinian world). The other was as the big honcho of the Royal Mint. Where they make the money.

In that second job, Newton had several interesting problems to deal with, which were in some ways more complex than how planets keep orbiting around stars and apples keep falling from trees. He needed to secure the coinage of the land against counterfeit, and in particular, to end the career of one particular master counterfeiter, William Chaloner.

This story is expertly chronicled in Newton and the Counterfeiter: The Unknown Detective Career of the World’s Greatest Scientist by Tom Levenson.

This is interesting for many reasons, including the fact that modern money, as we know it today (not coinage … that’s old … but the mint system itself) was pretty new, and modern law enforcement as we know of it today simply didn’t exist.

Of this book, Levenson notes:

Newton, I found, was a bureaucrat, a man with a job running England’s money supply at a time with surprising parallels to our own: new, poorly understood financial engineering to deal with what was a national currency and economic crisis. He was asked to think about money, and he did–and at the same time, he was given the job of Warden of the Mint, which among other duties put him charge of policing those who would fake or undermine the King’s coins. So there I had it: a gripping true crime story, with life-and-death stakes and enough information to follow my leading characters through the bad streets and worse jails of London–and one that at the same time let me explore some of critical moves in the making of the world we inhabit through the mind and feelings of perhaps the greatest scientific thinker who ever lived. How could I resist that?

Those were the days … when a physicist could murder a counterfeiter in the name of the King

William Chaloner, the counterfeiter, reminds me of a handful of people I’ve known. He possessed a sense of entitlement balanced by a remarkable capacity for greed and tempered with an acute sociopathy. He clearly had a keen intellect and extraordinary manual skill. When Isaac Newton murdered Chaloner (to put it the way Chaloner would put it) he did the world a favor. I’m not saying that certain people I’ve known should be hanged, gutted, and sliced like a chicken into five or six parts, but one can see why the idea would have been attractive back in the late 17th century when that was the usual practice for dealing with treasonous individuals in London.
Newton and the Counterfeiter: The Unknown Detective Career of the World’s Greatest Scientistrelates the days when Isaac Newton, in his job as Warden of the Mint (housed in the Tower of London) engaged in a long term game of cat and mouse with the criminal and counterfeiter Chaloner, over the course of several years in the late 17th century. A very striking part of this story is the nature of the legal system and the role of due process in courts in London and Middlesex County. For Levenson’s story, we (eventually) find Newton prosecuting a case against the counterfeiter. So that’s the first difference. Instead of having prosecutors, they had physicists (or whomever) arguing as plaintiff. And, on the other side of it, it seems defendants were often defending themselves. Of particular interest is the apparent fact that while Chaloner was probably guilty of everything we think of him as being guilty of (mainly forging coins and to a lesser extent paper instruments) Newton’s case was largely invalid and should have been thrown out. For reasons I’m not entirely clear on, Levenson does not conjecture at any length or depth about why Newton tried the case in the “wrong” court (county instead of city, essentially) and why he pretty much fabricated one set of charges to reflect reality in some ways but to be factually utterly incorrect, and thus invalid, in others. Did Newton carry out a prosecution that an excellent lawyer would have easily undone (in the first case, or on appeal) in order to torment the lawyerless Chaloner, who does seem to go nearly insane with the idea that his conviction was tantamount to “murder?”

And there are, of course, other details of the legal system that would make a modern American first cringe, then think about the American Revolution some 75 years later, and then think “oh, that revolution certainly was a good idea.” There are numerous key points in the American Constitutional system that one realizes are direct outcomes of abuses possible (and seemingly common) under the old British system.

Newton may or may not have tortured Chaloner or others he detained or prosecuted, but it is interesting that torture was officially illegal at the time, and Levenson discusses the legality and practice of torture over the previous century or so. I won’t reiterate the discussion here; When you read the book you will find it interesting.

I spent several years as an archaeologist digging up 16th and 17th century European (including British) coins. Not many of them, but those that did turn up on early sites usually proved interesting and important. The early colonists in Boston carried vats of King James I farthings, which had become worthless and disdained, to trade with the Native Americans as though they were glass beads or bangles. The Natives in Massachusetts rolled the farthings (small thin copper disks with a tin plate) into tubes and used them as one might use a tubular glass bead. Flat farthings were found in Euro-colonial contexts (not yet traded) and tubulated farthings were found with trade goods or on Native sites (though this was uncommon). And there were other interesting things about digging up coins, but I have already digressed enough. My point is simply this: Reading in Levenson’s book about the production of coins, the problems of valuation, international trade and value imbalances, counterfeiting, and so on was especially interesting to me because I dug some of those suckers up.

It occurs to me that I may have dug up coins actually made by Isaac Newton (well, under his supervision). Until I read Newton and the Counterfeiter, that had never dawned to me.

Another point: I had no idea there was a sex toy industry in 17th Century England. But of course, there would be.

I worked with someone years ago on a project looking into the evolutionary psychology of money, including the acceptance of both coins and paper as interchangeable or, at least, “worth something” in relation to, the usual human needs for which we are probably evolved to deal: Sex, food, shelter, whatever. Many humans have, indeed, incorporated money into their psychology. I was reminded of those readings, writings, discussions.

I had not really paid attention to the fact that Newton was mainly an alchemist for much off his scholarly life, and that this whole physics thing was sort of a side trip for him. If only he had insights of the sort he had for mechanics but for chemical bonds and elements.

Finally, Newton and the Counterfeiter: The Unknown Detective Career of the World’s Greatest Scientist presents a description of intellectual or academic life in England one or two “eras” before Darwin, contemporary with the early Natural Philosophers. That is not the intent of the book, but it serves that purpose and I enjoyed that aspect of the story.

The Disappearance of the Rainforest of the Sea

Let Them Eat Shrimp: The Tragic Disappearance of the Rainforests of the Sea by Kennedy Warne has been out for about a year, but if you’ve not seen it you may want to have a look at it. Warne, editor of New Zealand Geographic magazine, is a naturalist who writes about the embattled mangrove swamps, which are a key part of many oceanic ecosystems as well as local and regional economies.

What’s the connection between a platter of jumbo shrimp at your local restaurant and murdered fishermen in Honduras, impoverished women in Ecuador, and disastrous hurricanes along America’s Gulf coast? Mangroves. Many people have never heard of these salt-water forests, but for those who depend on their riches, mangroves are indispensable. They are natural storm barriers, home to innumerable exotic creatures—from crabeating vipers to man-eating tigers—and provide food and livelihoods to millions of coastal dwellers. Now they are being destroyed to make way for shrimp farming and other coastal development. For those who stand in the way of these industries, the consequences can be deadly.

In Let Them Eat Shrimp, Kennedy Warne takes readers into the muddy battle zone that is the mangrove forest. A tangle of snaking roots and twisted trunks, mangroves are often dismissed as foul wastelands. In fact, they are supermarkets of the sea, providing shellfish, crabs, honey, timber, and charcoal to coastal communities from Florida to South America to New Zealand. Generations have built their lives around mangroves and consider these swamps sacred.

This is complicated. Mangrove habitats have a distinctive set of plants and animals and a typical set of ecological systems that reside in them, and are distributed around the world everywhere that is not too cold, where the continents meet the seas. But each region is different in the exact link to inland and oceanic system and the relationship between traditional human societies and natural resources. In addition, scientific, conservation, and political interests and stakeholders make up myriad stories of involvement. Warne deals with this diversity in Let Them Eat Shrimp by producing over a dozen separate essays chronicling his own investigations in disparate locations around the world, and in so doing weaves a rich tapestry made up of mud, funny looking trees, edible animals and the people who eat them, the natives, nations, scientists and other interested parties. Global warming, sea level rise, globalization of the food supply, indigenous rights, and numerous personal stories are all part of the weft and warp of this complex cloth. I’m actually thinking of using a few chapters of this book in an upcoming Anthropology class.

I’m sure you’ve experienced this: You are at the grocery store, or in a restaurant, faced with a set of choices as to which vertebrate or invertebrate life form you will chose for your dinner. You left your handy dandy reference card that tells you which sea food to avoid, which sea food to eat, in order to do the least damage to the planet. You instinctively know that this is a rather complicated problem with many factors involved many of which you can’t even imagine. Read this book, then you can imagine, even know about, some of them!

The question arises…What can we do to help reverse the mangrove decline? I suspect that our greatest contribution, as individuals and communities, is to be responsible consumers, aware that our economic choices ahve global consequences. We can demand that suppliers and purveyors demonstrate that the seafood we eat comes form sustainable sources, and we can vote with our palates and pockets if it doesn’t.

Furthermore, we can insist that food be not just ecologically sound but socially fair–to the extent that fairness is possible in an unequal world. We can refuse to give our business to companies that are known to trade in the marginalization of the poor.

Yeah, like that.

Across Atlantic Ice: Clovis Origins

I want to talk about the book Across Atlantic Ice: The Origin of America’s Clovis Culture. It was written by Dennis Stanford and Bruce Bradley, both highly respected archaeologists. The point they make in the book is very simple: An important archaeological culture known as the “Clovis” is actually a European culture that traveled east to west from Europe to North America, arriving first along the New England coast and then fairly quickly spreading across the US to the Rockies, and subsequently kinda petering out though there are bits and pieces of Clovis looking stuff farther west.

From the book’s publisher:

Who were the first humans to inhabit North America? According to the now familiar story, mammal hunters entered the continent some 12,000 years ago via a land bridge that spanned the Bering Sea. The presence of these early New World people was established by distinctive stone tools belonging to the Clovis culture. But are the Clovis tools Asian in origin?

Drawing from original archaeological analysis, paleoclimatic research, and genetic studies, noted archaeologists Dennis J. Stanford and Bruce A. Bradley challenge the old narrative and, in the process, counter traditional–and often subjective–approaches to archaeological testing for historical relatedness.

The authors apply rigorous scholarship to a hypothesis that places the technological antecedents of Clovis in Europe and posits that the first Americans crossed the Atlantic by boat and arrived earlier than previously thought. Supplying archaeological and oceanographic evidence to support this assertion, the book dismantles the old paradigm while persuasively linking Clovis technology with the culture of the Solutrean people who occupied France and Spain more than 20,000 years ago.

This flies in the face of everything everybody thinks, except for those of us who have been thinking that something like this may have happened all along. I’ve always thought this was possible, if not probable, for two reasons: 1) Clovis looks more like Europe than it looks like anything else, even though I don’t see any immediate comparison (contra Stanford and Bradley who do). I also don’t need an immediate comparison. I don’t need an archaeological culture that looks just like Clovis to be in Europe, since the time period during which such a culture would have existed was during lowest sea level stands. An entire sub-continent worth of land is now inundated by the sea, and if Clovis is truly coastal it would be truly invisible in Europe. Why did Clovis go from coastal to inland in the North Atlantic in the New World and not the old world? Stupid question. People do stuff like that all the time.

If you live many months of the year on the ice at the edge of the sea, Europe and North America are one place.

The second reason is even more compelling and is the first thing I noticed. Despite intransigent denialim by North American archaeologist, Clovis appears in the east first, then moves west, and does not really cross the Rockies. No amount of pretending it is found first in the west (where it hardly exists) and moved east (against the tide of C14 dates) will change those facts.

One might suggest that this causes a problem because Native Americans are from Asia and Clovis can’t therefore be from Europe. It might help to know that in most places in North America, where Clovis occurs, it is followed by nothingness or at best notmuchingness. There is very little continuity from Clovis to later cultures, not enough to require that the same people stuck around everywhere. I regard Clovis as one intrusion in to a mostly empty continetn, not the first, not the last, probably preceded by relative but not complete emptiness in most places in North America, and followed, probably, but periods of population decline probably owing to climate change. But that’s just me; I don’t accept that the past is simple no matter how complex the present is. Rather, I think the complexity of human land use and migration is probably one of those general rules that applies across time and space at archaeological scales.

Climate change book for young readers

What are Global Warming and Climate Change?: Answers for Young Readers is a fairly unique book, as far as I know. It explains climate change, contextualized global warming, discusses causes and consequences and directly addresses the politics of climate change and global warming. The official book description:

Global warming is one of the most talked about science subjects today. Maybe you have seen pictures of polar bears or other animals stranded atop floating chunks of melting ice. Perhaps you have heard about or lived through extreme weather – hurricanes, floods, water shortages, heat waves, or electricity blackouts. Many of these events can stem from the world getting warmer. As that happens, the climate changes, too. This book helps young readers understand the sciences used to study global warming. Each chapter addresses specific questions about why the temperatures of the earth’s air and oceans are rising. The information presented aligns with the findings of the Intergovernmental Panel on Climate Change: that most of the warming observed over the last half-century is due to human activities and that the impacts of global warming will be significantly negative. Using a question-and-answer format supplemented by hands-on activities, this book fosters an understanding of the complex processes at work in global warming while also enabling youngsters to think critically about their future. McCutcheon ends his book by offering young readers productive ways to think about – and act on – changes in the environment contributing to climate change. McCutcheon taps his mastery of a complicated, highly charged topic to permit young readers to become informed consumers of sciences associated with the most urgent topic of their future – global warming.

Perfect for an earth science or environmental science class in middle school or for the youngish home schooler. Now we need one for high school!

It is a textbook like hard cover, nicely laid out and richly illustrated. The book does a great job of dealing with modeling, climate-weather distinction, and the longer term history of human impact on the environment. The activities are fun and useful. Personally, I want every 9-12 year old to have this book.

Illustrated Guide to Home Biology Experiments (book review)

One of the more popular books I’ve ever reviewed here, judging by the number of people who read the review, was this one on home chemistry. Now, let’s see if we can meet or beat the physical sciences with this new title:Illustrated Guide to Home Biology Experiments: All Lab, No Lecture (DIY Science). Robert Bruce Thompson, author of the chemistry book, has teamed up with Barbara Fritchman Thompson, to produce this new work.

The book has a lot of experiments in it, organized in a reasonable way, with complete instructions on everything. I would prefer to see more graphics illustrating the procedures and materials, but there are illustrations and they are good. I would just like more. The 30 or so experiments (parsed out into a much larger number of procedures) is targeted towards middle and high school students and in particular, home schoolers, but also hobbyists. The Illustrated Guide to Home Biology Experiments: All Lab, No Lecture (DIY Science) is designed to be used along side a biology text.

One of the best ways to evaluate a book like this may be to look at the Table of Contents. So, here it is, unformatted: Continue reading Illustrated Guide to Home Biology Experiments (book review)

Wonderful Life with the Elements

Have ever really thought about the elements? Have you ever really asked questions about them? If you are some kind of scientist or science geek, you probably know a lot about them, and that could even be a disadvantage for you, in a sense. For instance, if you learned early on that elements were formed at certain points in time and in certain places (the big bang or later in stars, for most atoms) then the following question may not have occurred to you: “What happens when a bunch of Carbon atoms get old. Do they fall apart?” Also, a sense of purity may be something you understand but others with less knowledge may not fully grasp. Breathing in “balloon gas” (which has some helium in it) can make your voice sound funny. Totally emptying out your lungs of all air and then filling them full with pure helium could cause you to be dead. Purity matters.

Every now and then you come across a book that takes the Periodic Table and transforms it into a learning experience about chemistry and stuff that can be really interesting. Wonderful Life with the Elements: The Periodic Table Personified is the latest effort I’m aware of to do that. This smallish, square book (read: Stocking Stuffer for your nerdy spouse or child) by Japanese artist Bunpei Yorifuji seems to follow a recent trend in books to be very quirky, perhaps to compete with on-line methods of accessing information. One method of getting chemistry across to people is to redo the iconography or the spatial metaphors of the Periodic Table. In this case, the elements are depicted as drawings of people who have various characteristics. You can look at a drawing and using what you know (using rather complex keys) infer stuff about the elements from the individual’s body, face, and clothing. A person standing there in their underwear may indicate an element useful in human nutrition. A person who appears to be dressed up in a robot suit is a human-made element, one that generally does not exist in nature, and so on.

Hair or hat styles relate to elemental families, and faces vary on the bases of the element’s subatomic characteristics. The elements are standing on things that suggest stuff about their uses. So, for instance, you might have this:

Gold

Gold has a big long beard indicating that it was discovered in ancient times. The figure representing gold and gold itself are a bit hefty of mass. Gold sports the hair style of a transition metal, and appears to be wearing Carharts, suggesting a multiplicity of purposes. There is quite a bit more information than this in this one figure.

The book comes with a nifty, full size fold out periodic table that I’m tempted to razor out and hang on my wall.
