COSMOLOGY
Is Everything We Know About The Universe Wrong?
"Dark flow is the latest in a long line of phenomena that have threatened to re-write the textbooks. Does it herald a new era of understanding, or does it simply mean that everything we know about the universe is wrong?"
9 PM Monday on Discovery Science. I enjoyed this hour about the standard model of cosmology and various concepts that had to be added as newer data became available. It will be repeated Tuesday, September 20 2011 12:00 AM. http://www.sciencechannel.ca/
Summary: "Dark Flow" is the latest finding from examinations of data collected about our universe. The hour covers the Big Bang theory (standard model of cosmology); the need to explain why the temperature is homogeneous throughout the universe (not an expected result of a Big Bang); Alan Guth's concept of inflation that answers the homogeneous temperature problem; rotation speeds of galaxies that led to the idea of dark matter which is required to explain why galaxies don't fly apart; the curious problem of how to detect dark matter; and finally the "dark flow" of matter discovered upon examination of CMB data (the cosmic microwave background). Is there more structure outside of our universe? Alan Guth predicted that our universe was part of a larger structure.
It doesn't get more fun than the exploration of ideas about cosmology!

EARTHQUAKE
You can check for "Felt Events - Last 7 Days" to see an accurate listing of quakes. If you've felt one, you can report how strong it felt to you in your town. Cool, huh?

SHOPPING
Good news/bad news ... from the folks at Toyota. Good: nothing expensive needs to be done now. Bad: I had asked them to do a thorough check and said I needed to keep it on the road for as long as possible. They inspected and told me that parts will be wearing out and I'll come to the point where it may not be cost effective to keep it. Boo hoo! I want to drive it forever.

THE GRAND DESIGN
Monday the 4th is much colder (16°C); an overcast gray day. This combination of sun and rain made the grass grow like crazy in 4 days.
Gray weather invites me to snuggle up with Terri & Flower and a good book. The great book that I'm reading now is The Grand Design by Stephen Hawking and Leonard Mlodinow. It's a marvelous overview connecting ideas and theories in physics from Newton's gravity through Feynman's view of quantum theory to M-theory; from the quarks that form protons and neutrons to the expanding universe/multiverse. With this model-dependent perspective of reality under your belt, various physics theories seem to fit into the jigsaw puzzle of Life, The Universe, and Everything more understandably. As some critics say, Hawking and Mlodinow may be too confident about M-theory and it may be trashed in the future but for this time and place in our universe, I like how well they explain all the concepts.

SUMMERTIME
Summer's shortness parallels the canine lifespan so that's another reason Terri and I enjoy as much time together as we can playing her favourite games.
