Nice effort by Mr Lam for our environment.. By using simple technology make bird’s house and giving data of surrounding air… We can also use this idea to make our atmosphere clean and clear….
Spacecraft cemetery,,, OMG!!! Like a graveyard for spacecraft objects, satellites and any other orbiting objects made by man… How difficult it would be to make an object entering back into the earth.. Making too much calculations …uff!!! MIR was of 142 tons..
In this project they are stopping the leaking of grounded carbon dioxide but what about that carbon dioxide which is on ground emitted through air conditioner, vehicles, factories, green houses etc…. And if they solidify carbon dioxide what would be use of that which is consuming too much water and money also???
MacDonald!!! A good place for people to share special moment of life… People gathered talk ,make connections , be social… Unfortunately I have allergies from all the things made at MacDonald except coffee and ice cream…
A good effort by CERN!!!! Use of horses for logging which is more environmently friendly….
Defination of learning is not defined easily I think… Everyone has their own measurements.. What we know we have learnt.. Professional learning is about activities, practice and hard work…
Congratulations to Magnolia which is good to be first country for the use of three words phrases address…. So now it would be easy for mangolians to drop or receive a mail…
As still as the sea!!! But after this new discovery by hydrophone it seems that old idiom is about to change now… As noisy as the sea…. It’s really surprising to know that the deepest point on the earth has a great hustle bustle than above the surface….
