Astounding facts about my heart…

  • Your body has about 5.6 liters (6 quarts) of blood. This 5.6 liters of blood circulates through the body three times every minute. In one day, the blood travels a total of 19,000 km (12,000 miles)—that’s four times the distance across the US from coast to coast.
  • The heart pumps about 1 million barrels of blood during an average lifetime—that’s enough to fill more than 3 super tankers.
  • lub-DUB, lub-DUB, lub-DUB. Sound familiar? If you listen to your heart beat, you’ll hear two sounds. These “lub” and “DUB” sounds are made by the heart valves as they open and close. See the valves in action.Julia Forte Artwork

The Very Large Array consists of 27 radio antennas, each weighing 230 tons and reaching 82 feet in diameter. The array, in the desert south of Socorro, New Mexico, combines to give the resolution of a 22-mile-wide antenna to aid scientists in the search for frequencies of molecules in interstellar space. Scenes from the movie Contact were shot at the VLA site.

I thought Contact (written by Carl Sagan) was a cool movie, but nothing compared to the PBS series “Cosmos” that Carl Sagan put together to vividly explain the universe and all of its wonder.

Thought this was cool too: The melodic use of the notes C#, D#, E, are recurring audio punctuations in Carl Sagan’s ‘Cosmos’, and also are used in key scenes of ‘Contact’. Notably when Dr. Arroway touches the then invisible interior of the space pod.

This little robot (Keepon) and others like it are being used to help children with autism spectrum disorders (ASD). It turns out that the children more readily accept “Keepon” as a means of social interaction, creating an an environment to help therapists draw the child out socially and study their emotional states. Quite an entertaining piece of helpful technology with cameras in its eyes and nose. Heck, I’d like to have one. Its a rockin stress reliever! Check out Keepon groovin to “I Turn My Camera On” by Spoon.

Nina Fedoroff has been the science and technology advisor to the US secretary of state since 2007, initially working with Condoleezza Rice. Under the new Obama administration, she now advises Hillary Clinton.

“We need to continue to decrease the growth rate of the global population; the planet can’t support many more people,” Dr Fedoroff said, stressing the need for humans to become much better at managing “wild lands”, and in particular water supplies.

Current world population – 6.8 billion

Net growth per day – 218,030

Mortality rate per day – 150,000 (approximation based on CIA – World Factbook )

Forecast made for 2040 – 9 billion

THE MOST POPULOUS NATIONS

China – 1.33 billion
India – 1.16 billion
USA – 306 million
Indonesia – 230 million
Brazil – 191 million
