Because I thought I might as well do myself a favor, I had a little crossover with my gaming comic. I suppose I shoulda mentioned I had another ongoing comic before. Oh well.

The Escapist Radio Theater appears every other Sunday on The Escapist. And it's a significantly different flavor than Question Duck is. Here's a link to the latest issue which came out just today. http://www.escapistmagazine.com/articles/view/comics/escapistradiotheater/8067-The-Escapis t-Radio-Theater-9

ps. If there isn't a comic tomorrow, please don't be surprised. It's Labor day and beautiful weather. And I make the best barbecue among my pals.

it probably burns imaginary calories

The consensus is that the human brain uses energy at a rate of 20 Watts.

Energy consumption of 20 Watts is 20 Joules per second.

A Kilocalorie = Calorie = 4184 Joules.

So a human brain uses a (Kilo)Calorie of energy in about 3.5 minutes.

idk what joules are

Hmm...joules are like the chemical units of energy...so the units to measure it. Its in the SI system. :)

Keke, sorry! I just had to answer it. Like this duck makes us answer these lovely qs.

And I never thought of that! Do we really burn a lot of calories when we think? Are smarter people skinnier than dumber ones?

Ahh...question duck. I blame you for this question madness. :D

joules is just the name given the units cause that's the scientist that discovered them

I do not think it is possible to lose weight by thinking alone. I do a lot of deep thinking, and have been told I am very intelligent (and have test results to prove it) but I am overweight. Healthy, but overweight from fat... so, yeah. Smart =/= thin

The answer is 42.

joules are (thinking, they taught us this in sixth grade) measurements of energy, I think. I dunno, I have to go back to my sixth grade science teacher.

Joules are a measurement of energy primarily utilized in science, notably physics equations. E.g. the amount of energy released when splitting an atom is measured in joules and approximately calculated using E=mc^2.

Similarly, calories are a measurement of energy. They are broken into "small" and "large" calories/Calories. One calorie equals roughly 4.2 joules, whereas one Calorie equals roughly 4.2 kilojoules.*

The calorie was measured by approximating the amount of time required to raise 1g of water's temperature by 1ÂșC. Thus, it is used regarding food as it has been found archaic for scientific use.*

An additional fun fact the human brain uses roughly 1/5 of the total energy used by your body.

So yeah, thinking burns a fair bit of calories.

I have no idea how this works for Ducks though.

Others here have given some values as to energy used by the brain, that I don't dispute.

However, the brain continues to use an appreciable amount of energy during times where we aren't 'actively' thinking. I do not know what difference in energy usage there is in a resting brain, vs an active one, but if there is it is likely to be smaller than the numbers listed above as the brain has a number of functions besides pure thinking

A lovely comic and interesting comments! Also made me smile that QD made him think. :)
