Thermodynamics Question of the Day

Let our journalists help you make sense of the noise: Subscribe to the Mother Jones Daily newsletter and get a recap of news that matters.


On a hot day, does closing the blinds keep your house cooler? The thermodynamics amateur in me says no: once heat is inside the house, it’s inside the house. And yet, people are always recommending this as a way of keeping inside temperatures down during heat waves. Who’s right?

Next up: Does evolution violate the second law of thermodynamics? Please provide a minimum of 20 typed, single-spaced pages of word salad to justify your answer.

UPDATE: Let me be clearer. These are interior curtains/blinds. With them open, sunlight streams in and heats up whatever it touches, which is then radiated/convected into the rest of the house. With them closed, sunlight hits the blinds, heats up the blinds, and then the heat is convected/radiated into the rest of the house. Net effect: identical.

If the blinds reflect some of the sunlight back, then that’s clearly a plus. But if not, then the total heat energy that enters the house via sunlight is the same either way. Or so it seems to me. But in any case, that’s the question.

SIX TRUTHS

Reclaiming power from those who abuse it often starts with telling the truth. And in "This Is How Authoritarians Get Defeated," MoJo's Monika Bauerlein unpacks six truths to remember during the homestretch of an election where democracy, truth, and decency are on the line.

Truth #1: The chaos is the point.

Truth #2: Team Reality is bigger than it seems.

Truth #3: Facebook owns this.

Truth #4: When we go to work, we're in the fight.

Truth #5: It's about minority rule.

Truth #6: The only thing that can save us is…us.

Please take a moment to see how all these truths add up, because what happens in the weeks and months ahead will reverberate for at least a generation and we better be prepared.

And if you think journalism like Mother Jones'—that calls it like it is, that will never acquiesce to power, that looks where others don't—can help guide us through this historic, high-stakes moment, and you're able to right now, please help us reach our $350,000 goal by October 31 with a donation today. It's all hands on deck for democracy.
