Real or Imaginary Time? Even Stephen Hawking Wasn’t Sure

I’ve been reading A Brief History of Time, Stephen Hawking’s bestseller. It’s a bit dated now, having been first published in 1988.  I’m not a scientist, but I imagine there have been many knowledge updates since then.

I found it tough in the beginning to get into the book, but now that I’m near the end, I’m really liking it. Not only do I enjoy building my scientific literacy, but the book started to read like a novel to me. Especially the chapter about black holes. Wow! What suspense! What characters! That poor astronaut who keeps getting sucked in and turned into spaghetti! (Those who have read the book will get my humor.) In fact, I appreciate that such a monumental mind had a sense of humor.

The book takes you on a journey, as the title says, through humans’ observations, theories and understanding of the nature of the universe, time, and space. Hawking walks you through how scientists actually conduct research into such an esoteric and controversial subject. There is so much we know now, and so much we still do not understand about the nature of our universe.

One can read this book in a vacuum, though I am certain Hawking would insist that there is no such thing as a vacuum in space. But I couldn’t shut out the current world political scene while reading parts of it.

One passage in particular jumped out at me for its absurdity. I loved it so much that I have copied it for my own reference. I took philosophy in college and loved it. It challenged my brain, and expanded my ways of thinking and analyzing situations. I have found Hawking’s writing much like philosophy. It puts things in perspective and sometimes makes you throw up your hands and surrender to the cosmos.

The Brain Twister

Following is the passage that so tickles me. It might amuse you, it might intrigue you, or it might simply annoy you. I might just let this guide my view of life from now on.

“This might suggest that the so-called imaginary time is really the real time, and that what we call real time is just a figment of our imaginations. In real time, the universe has a beginning and an end at singularities that form a boundary to space-time and at which the laws of science break down. But in imaginary time, there are no singularities or boundaries. So maybe what we call imaginary time is really more basic, and what we call real is just an idea that we invent to help us describe what we think the universe is like. But according to the approach I described in Chapter 1, a scientific theory is just a mathematical model we make to describe our observations: it exists only in our minds.  So it is meaningless to ask: which is real, “real” or “imaginary” time? It is simply a matter of which is the more useful description.”

Got that?

Bonus

While reading A Brief History of Time, I felt my brain being stretched to its limits, much like the astronaut being stretched to death in that black hole. What sprang to mind was one of my favorite and most appropriate Far Side cartoons from decades ago.

The Nest Box

Nesting season is over. I went out to clean out my chickadee box. I had seen Bewick’s wrens in the spring, bringing nest material to it. I got so excited, I figured wrens had beaten chickadees to prime real estate. I watched and watched. But after a while did not see any wren activity at the box. I assumed they had abandoned it.

I also watched for chickadees, but never saw any going in or out.

But opening the box just now, I got such a surprise! A beautiful little nest. There must have been a clutch! But whose?

Here’s the nest. You can see moss, twigs, feathers and other materials.

Columbines: Enchanting and Toxic!

What caught my eye against the red-rust bricks was the softness of the purple-blue and white petals, like bits of angel wings.

The shapes made me think of cranes and swans and butterfly wings; even dragons. They had a most delicate appearance, ethereal.

As it sometimes happens, an object in death can be as beautiful as it was when alive, just different.

The spent columbine petals lay assembled in various random poses, but could not have been more artistic if they had been purposely placed. I ran for my camera.

These magical columbines came with the house I bought 13 years ago. For years, there were very few, just about hidden beneath some shrubs. It took me a few years to discover them, coming to recognize their distinctive rounded lobed leaves. I quickly came to cherish the secretive blooms.

By this year they have spread and I had more little purple flowers than ever. Some gardeners almost regard them as pests. I wholeheartedly invite them to spread across the entire yard.

Widespread Wildflowers

Wild columbines are native to Europe, Asia and Northern Africa, but they have been widely cultivated as garden flowers in the United States. The five-petaled flowers come in many colors, from purple and blue, to pink and orange.

Aquilegia, their Latin name, pays tribute to the flower shapes, with spurs jutting out from the rear.

These spurs hold nectar and were thought to resemble eagle claws or beaks. Aquila is Latin for “eagle.”

Traditional uses

Columbines are said to symbolize wisdom, strength and happiness. It has served as a religious symbol of purity and has appeared in paintings with the Virgin Mary. It was also considered sacred to the goddess Venus.

Like many wildflowers, columbines have been used medicinally since the Middle Ages. All parts have been used, including the roots, flowers, leaves and seeds. The medicinal uses were many. It has served as a remedy for fevers, rhinitis, swollen lymph nodes, bloody coughs, jaundice and gall bladder ailments. The plant contains several alkaloids, triterpenoid saponins, flavonoids, and small amounts of cyanogenic glycosides.

Though columbines are considered toxic, the flowers have some astringent and antiseptic properties. The root has been used as a topical treatment for eczema. It is not recommended to consume any parts of the plant, as it contains cardiogenic toxins which can cause gastroenteritis and heart palpitations. Ingestion of large amounts of the fresh herb can cause convulsions, breathing problems and heart weakness.

Best to enjoy these storied flowers from a distance!

Just for fun, take your own Rorschach test: see what the petal shapes remind you of.

Bunny Visit

On a recent morning, as I was lifting the window blinds, I saw a tiny bunny munching on grass in my front yard. What a sweet surprise! It looked very small and seemed completely at ease.

I do occasionally see them around, cottontail rabbits, but not often in my yard. Once in a while one shows up on my camera trap that is set up in the back.

Cottontails are common throughout North, Central and South America. If you want to get uber scientific, there are many subgenera, such as Eastern cottontail, desert cottontail, mountain cottontail and swamp rabbit. Most have the little white fluff that gives them their name.

Females can have up to three litters a year, with an average of four young. they grow quickly and are considered full grown at three months! They live in burrows and are quite sociable with others in their group.

The life of these cuddly creatures is short though, averaging two years. They are appealing to many predators, including birds of prey, foxes, coyotes, cougars, dogs, cats, snakes and even squirrels!

I was able to get some good photos of my visitor before she or he left.
