#Lights Archives – THE PAGE TURNS

The Kajmeister backyard has its own small but cheery arrangements.

Imagine you are a tiny speck attached to a giant rotating space ship, not spinning too fast for you to fall off, but enough so that you notice that things change in your environment. Sometimes, there is a nearby furnace with plenty of light and heat but you can’t get close to it all the time because of the spinning, so you have to plan your energy use carefully. Also, some time ago, way before you were born, the space ship was hit by a big rock, so hard that it tilted sideways, so now the whole thing is tilted and wobbly. Although it’s so big and you’re so small, you don’t really notice. EXCEPT! that when you’re on the side tilted toward the orb, it’s plenty warm but when you’re on the side tilted and wobbling away, it’s not always warm enough. You kind of count the hours until you start tilting toward the orb again.

That’s the Solstice. Happy Solstice.

We carbon-based lifeforms like our solar radiation, that light and warmth that’s much better when we’re tilted TOWARD and not away. We’ve been tilting away, but now, starting yesterday we started TOWARD again. Our ancestors liked this so much that culture after culture dragged giant stones up mountains, across logs, along ramps, just to put together towers big enough so that everybody knew when the space ship would start spinning toward the orb again.

Happy Diwali! Happy Flashback Saturday! I thought it would be worth reposting what I wrote three years ago about lights in the coming of winter. I noticed many of us are putting up Christmas lights early–fantastic! We need ’em. Trees, too? Sure! Even if no one beyond your pod can visit inside your house–and they should not!– they can drive by and look… or you could take turns doing a Zoom tour of the inside for family and friends. Be creative. Stay safe! Be grateful that you are all still here.

There is a light at the end of the tunnel, even though it’s still dim. Here’s my post, from December 20, 2017.

I highlighted a recent sentiment that Christmas lights make everything better. This is no accident. Tomorrow is the winter solstice, the shortest day of the year in the northern hemisphere. Our body clocks can’t wait for that turning of the tide and, over centuries, our cultures have created one tradition after another to add lights which stave off that darkness. That desire for more light is built into us at the core, even at the cellular levels, within our circadian rhythms.

Fascinatin’ Rhythm

Hall, Rosbash, and Young won the 2017 Nobel Prize in Physiology and Medicine for studying the phenomenon of circadian rhythms. The basic notion of a circadian cycle is one tied to a 24-hour biological clock, a circuit fundamentally tied to the length of a day, split between sun and darkness. Life cycles, for everything from plants to fruit flies to human beings, have adapted to that 24-hour pattern. Scientists have known for years that key processes that regulate sleep, hormone production, metabolism, and behavior are linked to these patterns. The Nobel scientists figured out why.
