degrees. they can be heard 300 miles from their source. they can be heard 20 miles from their source. so the pingers battery dying would be a real complication here. sure. not to mention that the acoustic equipment can actually rebound, so to speak, echo throwing things off even more. so it is promising they were able to hold on to the sound consistent with the transmission of airplane black boxes for over two hours and then again pick it up for 13. how crucial is it for them to find it? because at this point they said they re trying to regain contact but have not been able to get those signals once again. are you there, sir? yes. i m here. yep. were you able to hear my question? i know that they told us that they re trying to regain contact but they ve not been able to get those pings after hearing it once for two hours, over two hours then another time for 13 minutes. how crucial is it for them to find it any time now in the next 24 hours or even in the days to
would be fantastic because it means we can hone in to a five to six-square-mile search. which goes from impossible to the probable. until we get that confirmation, we can t confirm that echo will help that. some skepticism last night at that news conference from one period of hearing these pings or this acoustic event and then on saturday another and he said that he would have expected a continuous sound. could that possibly not be this continuous acoustic event as they described it, being attributed to the battery dying. when a battery dies on a pinger on a black box, does it go in and out or when it dies it s done? no, the skepticism or at least the comment that the air chief marshal made, basically
academy of engineering announced the winners of two important prizes. the draper prize is often referred to as the nobel prize of engineering. this year it went to four pioneers of the liquid crystal display. lcds are on your smartphone and tv. we take them for granted, but they have changed the way we live. liquid crystals use energy much more efficiently than earlier display technologies did. lcds are a large part of the reason you can watch an entire movie on your hand held device without the battery dying. and the four draper prize winners were cited for their accomplishments in the 1960s and 70s. technology that s now utilized in billions of consumer and professional devices. for those accomplishments, i salute the winners, but they had to learn their skills somewhere and that s what the national academy of engineers gordon prize celebrates. the three women winners of the
as we count down to new hampshire, the economy is still the driving force in the minds of voters in the united states. but is it the driving force in the republican primary? welcome to your money. i m ali velshi. the latest cnn/opinion research corporation poll shows 57% of americans think that the economy is the most important issue facing this country. i want to bring in cnn senior political analyst david gergen. david, the polls say mitt romney has the best chance to beat president obama in the republican field. do conservatives still reluctant to get behind romney feel he lacks what it takes to turn the economy around or is it something else all together? he is actually doing well when people asked is your most important issue the economy in iowa. he won a healthy plurality of those voters who thought the economy was number one. he s having some trouble connecting with voters emotionally. they seem stiff, reserved, can t quite understand him, santorum in the case of i
