It thus takes the shape of a pancake (again) but this time, the drop is in midair. This phenomenon is different to a drop falling on other surfaces as in this case, the drop crashes on the surface leaving only a small quantity of the water to bounce up. Physicists have also found out that the actual speed of a drop influences its deformation but not the time taken for it to get in contact with the surface. Article: Do you know what happens when a drop of water hits a non-absorbent surface? Yeah you’re right (if you don’t have the answer, please re-read the title of this column), the drop echo upwards. A French scientific team from the Collēge de France have studied the scene sparingly with a concave lens that took 40000 images per second. Here are the results: At first, when it hits the surface, the drop flattens. Then, it signal up due to the movement energy it had when falling down. The drop will continue going upwards eventually taking the shape of a needle. Afterwards, the drop falls upon itself, into itself. It thus takes the shape of a pancake (again) but this time, the drop is in midair. This phenomenon is different to a drop falling on other surfaces as in this case, the drop crashes on the surface leaving only a small quantity of the water to trip up. Physicists have also found out that the realized speed of a drop influences its deformation but not the time taken for it to get in contact with the surface. This veritably depends upon the mass of the drop. Anyway why is all this stuff important anyway? Scientists swear by that this find may be of interest to the industry. There’s a small illustration: Imagine not seeing droplets of rain on your car’s windscreen when it is in fact raining cats and dogs outside. Cool, isn’t it? Well this may well be possible with these new data obtained by the scientists from the Collēge de France. How though? Easy enough! The period of contact of the raindrops with the windscreen is so minimal that the driver does not even see them! Water drops bounce like springs, would you ever have thought of this? No, I’m not sure you would.

How the Meter Came To Be Summary: Barely a year later, in March 30, 1791, has this same assembly accepted the new proposal of the French Academy of Sciences which adhered to the second approach: that the new definition of the meter would be equal to one-fourth the polar circumference of the world. It must be noted that the circumference of the Earth, if measured through the poles, is about forty million meters. In December 10, 1799, the French National Assembly then specified that the final standards would be accordin… 2.

Exploring the Universe with Dr. Norio Kaifu Summary: Professor Kaifu is the director of the Subaru Telescope, National Astronomical Observatory of Japan (NAOJ) and has held the position as vice president of the International Astronomical Union (IAU) since 1997. Dr. Kaifu shared his views about the design of the new telescope, cylindrical in shape, rather than dome, it can be more optimal for wind resistance. Mauna Kea was chosen as a location for the new Japanese telescope because of the stable weather and easy access. Article:During 1998… 4. Only knowledge from above... Summary: Let me explain, please.Before Nicolaus Copernicus (1473-1543) defied the teachings of the Roman Catholic Church by saying that the earth moves around the sun (the church believed that the earth was the center of the universe and the sun and stars revolved around it), he was risking his life.But Copernicus was not afraid to speak out about his knowledge of the heavens, and the world of modern science owes him a debt of gratitude (Copernicus was a scientist and devout Christian). So, a fr… |
