  This is just one case in myriads where scientists don't seem to understand a very simple phenomenon! The flight is the particularly notorious one. They say that the wing is so shaped that the air moving at the top is faster than the one moving at the bottom. But it is not clear why it must do so. There is no rule which says 'the air branching off a region must arrive at a given region at the same time, so that if one part has to move over a longer distance, it must move faster.
  
  Why do they ignore the straight foward explanation: titling the 'nose' of the plane upwards makes the plane move upward just the same way the wind turbine is moved in a direction perpendicular to the air because of the similar tilting??

  Why is the sky blue? The official explanation is that light is scattered off the dust and it so happens that the light of 'blue' frequency donnot attenuate much over distance. I don't like this explanation. It doesn't explain why not all planets appear blue! Why are some red, brown, green etc. It even does not explain why every distant object does not appear blue. A better explanation is that the earth's atmosphere itself is blue. The mixture of air at the ratio as is on earth is tenuous blue. It appears transparent because we see only a small portion of it. However, looking upwards, we see layers upon layers stacked together.

  Strictly speaking, we mix the dies and the light, not the colors. A blue die absorbs the light of all the colors (frequencies) and reflects only the 'blue' frequency. So if you mix it with a 'red' die, some of the 'red' reflected by the 'red' die will be absorbed by the 'blue' die. Similarly some of the 'blue' reflected by the 'blue' die will be absorbed by the 'red' die. In a similar way, if you mix dies of all colors, any 'color' reflected by any die will be absorbed by all the others. So the resulting mixture ends up absorbing all the colors.

  German taxpayers must be wincing (slight involuntary grimace,) when they note the eye-watering amounts they are forced to pay, into the EU budget...
  Germany is now the single biggest contributor to Brussels....and the financial weight is crushing that nation, especially since Britain left the punishment club and no longer shares the burden...
  
  Good luck to AfD efforts to gain power...Germany needs to support that party...Or they will go under...
  
  Moreover, didn't dopey Joe Biden recently suggest that Albania and the Balkans, join the EU...?? If they do join, the fiscal burden on Germany, will skyrocket....EVEN HIGHER.......

  The moon had never allowed a human being to see what is on its back!

  Thre are 3 very fascinating facts about the moon that cannot all be 'coincidence'
  
  1.) The moon looks exactly the same size as the sun
  2.) The moon rotates at the same rate as it revolves around the earth.
  3.) The far side of the moon is dramatically different from its near side!

  How big must a lamp on moon be for it to be visible on earth even under the most powerful telescope? It must be several kilometres big! Is there such a bulb on moon?

  The fact that you can post/talk/share just about anything & everything, is a big plus for all.
