The eggs were laid on or about March 14, 2007 and the older sibling, Boris, hatched sometime in the evening of April 19th. The younger sibling, Natasha, emerged from her egg at 5:30PM the following day, April 20. We expect the siblings to fledge sometime during the first week of June, at which time they'll look very similar to their parents.

When he walked to the edge of his property line, he found tractors from the abutting coal mine digging into his land. Soon he saw his local creek, once clean and healthy, turn brown and muddy. This is the story of McKinley Sumner's fight to protect his property. 247 tag:techtv.mit.edu,:Array/187511100 2009-06-30 14:12:10 -0400 MIT Department of Physics Technical Services Group A wire frame is dipped in bubble solution and placed in front of a speaker. At certain frequencies, the soap film oscillates in symmetrical patterns called <a href="http://en.wikipedia.org/wiki/Normal_mode">normal modes</a>.<br><br> A light is reflected off the soap film through a lens onto the wall to show these normal modes as the frequency of the function generator is increased. The first set of normal modes occur at frequencies lower than we can hear with our ears, which is why you can't hear the speaker in the video until the frequency is increased. 268
