Wood Stove. Big Deal!

The four biggest killers of the world's poor are hunger, dirty water, indoor smoke and malaria which kill 7, 3, 3 and 2 people per minute (p.338). There are 500,000 minutes in a year.

Now consider the Envirofit G-3300 stove. "These stoves reduce smoke and harmful gases by up to 80 percent, reduce fuel use by up to 60 percent and reduce cooking time by up to 50 percent compared to traditional cooking fires and stoves."

How to use Google better:

BTW, the advice on screen capturing is for a Mac. On a PC use the "print screen" button. You can crop the picture elsewhere. (Eg. On Word, crop the picture, then copy and paste to make to crop permanent.)

World's Longest-Running Experiment

Is brittle coal pitch a liquid or solid?
85 year-long experiment continues.
You can watch it unfold live. The next drop
is expected around 2013.

Alternative Certification

Some people can learn from books. Some need a teacher. The downside of teachers is that we are expensive and not very responsive at 2:00 in the morning or whenever you might most like to learn. Either way, however, reliable, professional teachers are needed to provide grading: to assure that the student has learned.

Uh oh!

Update: Sept '14
It is only one study, possibly biased (the article says little about method and I am too lazy to research further.) but MIT says that online courses teach as well as classrooms. Uh oh!

A tricorder?*

Somewhere in the infrared range of the electromagnetic spectrum there are terrahertz waves that can penetrate human bodies and react differently to different chemicals. We have large lab devices to make these. We may soon have small ones. Possibilities!

Repeat: there is serious talk of a handheld, non-contact device that can analyse the inside of a human.

*A tricorder is a gizmo from Star Trek. It is a handheld device that can analyse things without opening or even touching them.

Thinking Like a Neanderthal

Neanderthal man had bigger brains than we homo sapiens do but they didn't think the same way. New Scientist has some ideas on how they would have thought.

Matt Ridley (the Rational Optimist) thinks the most important difference was our eagerness to trade. By trading, we benefit from our own innovations as well as the other guys' innovations and the innovations of everyone he knows. We might not have been smart enough to think of connecting a sharp rock to a straight stick, but if we meet anyone who was, we get sharp spears too.

A Different Approach to Global Warming

What if action on global warming focused on something other than CO2. What if it was more effective? A new study investigates how we could reduce warming by concentrating on methane and carbon black (soot).

On Goldilocks and Climate Change

So are we cooking under greenhouse gasses or on the verge of a new ice age? Or mightn't it be both?

American Finances Made Simple

Don't enjoy too much schadenfreude. Canada is only half as bad (though we are far better when it comes to new debt).

"Jellyfish Cotylorhiza tuberculata drifting just beneath the surface looking for capturing the first sunrays to trigger their symbiotic algae to produce energy for it."

And that's just honorable mention.

Would You Rather be Pretty or Hot?

I know the answer pushed by MTV or the average Axe commercial. I wonder though, is that the girl's best interest.

What Do You Want to Be When You Grow Up?

Job prospects are poor these days and the economic fundamentals don't look to improve. Here are some bright spots (US data). Here are some impostors.

If you are hoping that an education might help, the answer is maybe. Here is how the subject you studied correlates to salaries and employment rates.

Emotional Intelligence for Aspergerites

The problem: how to show the sympathy and empathy that leads to great social interactions when the fact is, hell! you're not all that sympathetic.

Plus algae blooms, ice swirls, moonrises and a volcano shooting right at you.

Speaking of Mental Health

Are we training ourselves to be distracted, superficial thinkers?

Do You Know Someone Worried About Alzheimer's

It turns out that Alzheimer's disease looks a lot like vitamin B12 deficiency...and the test for B12 deficiency is expensive ($100 or so) so it is not done that routinely.
