He leads a large team which assures the sucess of CERES ( Clouds and the Earth's Radiant Energy System ).]]> 2017-11-09 22:09:48 UTC https://padlet.com/ouattarahanna/yds81k44nvb3/wish/205526374 ouattarahanna https://padlet.com/ouattarahanna/yds81k44nvb3/wish/205528659 I like Dr. Loeb because he is humble, he has accomplished a lot, but he still thinks that he has more work to do. He hopes one day help us understand climate in a better way.]]> 2017-11-09 22:21:37 UTC https://padlet.com/ouattarahanna/yds81k44nvb3/wish/205528659 ouattarahanna https://padlet.com/ouattarahanna/yds81k44nvb3/wish/205530798 2017-11-09 22:31:23 UTC https://padlet.com/ouattarahanna/yds81k44nvb3/wish/205530798 ouattarahanna https://padlet.com/ouattarahanna/yds81k44nvb3/wish/205531813 Norman Loeb with a CERES model]]> 2017-11-09 22:36:03 UTC https://padlet.com/ouattarahanna/yds81k44nvb3/wish/205531813 ouattarahanna https://padlet.com/ouattarahanna/yds81k44nvb3/wish/205532522 This year, Loeb won the Exceptional Scientific Achievement medal for his unusually significant scientific contribution toward achieving NASA's mission.

Tides are caused by the Moon's gravitational force towards the Earth. The attraction stretches the Earth which gives a "rugby ball" shape with two bulges. On the bulge that faces the moon, we find high tides, and on the other bulge, on the opposite side, we find low tides.]]> 2018-01-11 15:47:30 UTC https://padlet.com/ouattarahanna/yds81k44nvb3/wish/220636808 ouattarahanna https://padlet.com/ouattarahanna/yds81k44nvb3/wish/220645182 "Any body plunged in a liquid is subject to a push acting from down to up equals to the weight of the liquid's volume displaced by the object."

How to calculate the Push of Archimedes ?
    take a dynanometer
    suspend an object to the dynanometer, note the value of the force (P₁)
    take a test-tube with water, note the volume (V₁)
    plunge the object suspended in the test-tube, note the final water's volume (V₂) and the value of force does the dynanometer indicate (P₂)
