Physics Week in Review: December 14, 2013

The winter solstice isn’t until next week, but the earliest sunset of the year already happened. How’s that possible? We’re getting awfully close to Christmas.

The winter solstice isn't until next week, but the earliest sunset of the year already happened. How's that possible?

We're getting awfully close to Christmas. Here's some gift ideas for the Physics Fanatic in All of Us: "as you shop for the traditional tally whack and knick-knack, throw in some super magnetic putty or a build-your-own AM/FM radio kit for the voracious, growing minds in your family." Related: Ten Smart Science Gifts For Kids: Don't buy your children robots this year—let them build their own. Also: Giving Science, Not Things -- holiday science gift ideas for adults -- and The Animal Lover’s Gift Guide. "Gratitude is not unique to our species, but the trading of gifts ... might just be."

The Nativity (scientifically accurate version). "So, basically, three men followed an unspecified bright object over hundreds of miles of desert in order to meet a baby, about whom all they knew was that it would have a nose, might need money and would eventually die. For this they were considered 'wise men.' This goes to show that wisdom is clearly a subjective term."

Introducing the Temperfect Phase-Change Mug: Engineer designs mug to keep coffee temperature just right. "At room temperature, Material X is a solid. But when you pour hot coffee into the mug, the heat dissipates through the stainless steel inner wall of the mug and is absorbed by Material X, which becomes a liquid. This pulls the temperature of the coffee down to 140 degrees F. As the coffee cools, Material X releases its heat back through the lining of the mug – keeping the coffee hot."
