To appreciate that some questions are better than others, it helps to consider a few examples of questions that are bad.

To find them, try playing Twenty Questions with a young child. In trying to guess an animal, a young child might ask: Is it a koala? Is it an elephant? (Not: Is it a mammal? Does it live in Africa?) These are bad questions in the sense that they're unlikely to yield an efficient solution to the problem of discovering the animal one's adversary has chosen.

Early-childhood and elementary school programs reflect a diverse set of commitments about what children ought to learn, and about how they ought to do so.

Some focus on academic preparation and advancement, with extra attention to reading and mathematics. Some emphasize social-emotional development and community values. Others tout their language classes, or their music program, or the opportunities for children to engage in extended projects of their choosing. Some praise structure and discipline; some prize autonomy and play.

A few years ago, my daughter requested that her nightly lullaby be replaced with a bedtime story.

I was happy to comply, and promptly invented stories full of imaginary creatures in elaborate plots intended to convey some important lesson about patience or hard work or being kind to others.

Those of my generation have seen enormous advances in speech recognition systems.

In the early days, the user had to train herself to the system, exaggerating phonemes, speaking in slow staccato bursts. These days, it's the system that trains itself to the user. The results aren't perfect, but they're pretty darn good.

Drawing the boundary between science and pseudoscience isn't always straightforward.

Amid the clear extremes is a murky territory occupied by bad science, fraudulent science, and sometimes even religion. Is creation science, for example, an example of bad science, pseudoscience, or something else entirely?

Beware Of 'Accuracy'

In a recent post, Adam Frank introduced some key ideas behind Bayesian statistics. He began with the example of a medical test for a disease, asking the question: How likely is it that I have the disease, given a positive result from a test that's 80 percent accurate?

On Jan. 9, 2007, 10 years ago today, Steve Jobs formally announced Apple's "revolutionary mobile phone" — a device that combined the functionality of an iPod, phone and Internet communication into a single unit, navigated by touch.

It was a huge milestone in the development of smartphones, which are now owned by a majority of American adults and are increasingly common across the globe.

Debunked conspiracy theories have been making the rounds on social media lately, from the thoroughly unsupported claim that millions of people voted illegally in California to false assertions about paid protesters being bused to demonstrations.

On Nov. 8, the World Meteorological Organization published a press release summarizing the findings from a report on global climate from 2011-2015.
