Continuing our BIG series we now look at the largest DRILL BIT use for tunneling these bits are huge and bore holes right through solid rock! Listen close you can almost hear the noise these bits make cutting through the earth...


The German company Astro- und Feinwerktechnik Adlershof GmbH has produced new transmitters for Herrenknecht AG mounted on their tunnel boring machine seen above. Every second the transmitters send sound waves into the ground, microphones receive the reflecting signals which are data processed and can visualize important geological changes up to 40 m in front of the rotary shear blade. These innovative transmitters have been developed using the expertise Astro gained during their work for ESA on the Cassini-Huygens spacecraft.

Today was Iron Bowl day here and Bama lost to the other team 28/18! The worst game I have seen them play all year! Well... Maybe next year! That is four in a row we have lost to them. You want to see a two MILLION dollar smile? Catch a pic. Of Coach Tubervill of Auburn!

Thought for the day, my grandpa use to say son, winning isn't every thing! I don't think I have ever seen a happy looser!
