I noticed several articles about scientists’ discovery of “Earth’s twin”. Subheads made me question this claim, so I decided to read one article further.
I am not a scientist, but I would argue against calling a planet a twin of Earth that has a “thick, gaseous atmosphere”, “orbits a red dwarf star”, is “60% larger than Earth”, and has surface temperatures “as high as 104C”.
My understanding of the word twin is that a certain similarity is required. Perhaps, scientists use a different definition...or do not learn or care about words.
I learned something, which I probably learned years ago in science class, but have forgotten. Even the laziest, most-indolent person is moving at 100,000 mph, which is the speed at which the earth moves in its orbit around the sun. That comforts me, because I can feel that I am active, even when I feel like doing nothing or when I do nothing..
Later in the same BBC program, I learned another forgotten fact. If you drive in a car at 60 mph on a road that runs along the equator in the direction of the earth’s rotation, you are actually moving at 1000 mph plus the 60 mph (1060 mph for the math-challenged among you), which is the speed of the car plus the rotation of the earth. (For the science-challenged, ie. Republicans, that’s a different speed than the one in the first paragraph.)
Now, are you not pleased that I passed on knowledge you may or may not have acquired in school, which will do you absolutely no good...but is interesting?
Anyone with a sense of humor, an appreciation of irony, and a minimum level of general knowledge (needed to get the irony!), will love Jon Stewart's Earth. (The Daily Show with Jon Stewart Presents Earth (The Book): A Visitor's Guide to the Human Race ) It's a book version of the best trockenbeerenauslese, chocolate truffles, or high-butterfat-contentbutter pecan ice cream: rich and satisfying. All are meant to be sipped or nibbled (except the ice cream, on which you can pig out) a bit at a time every few days and savored in a world of banal flavors.
If you're looking for something more intellectually stimulating and challenging, then you should try Richard Dawkins' fascinating book. The Ancestor's Tale: A Pilgrimage to the Dawn of Evolution
