Physics
I understand it has something to do with efficiency and cost of manufacturing, helicopters generally only have 2, 3, or 4 blades and they're expensive. Computer fans can have upwards of 50 blades and their main purpose is to get a lot of air pushed through just as much as the helicopter.
I guess the overall question is whay do you gain and lose as you increase the number of blades on a turbine or propellor.?
Physics
I'm Dr. Harry Cliff, a particle physicist who works with the LHC to answer some of the biggest and most mysterious questions of the universe. In my new book, , I explore mysterious anomalies in contemporary physics and profile the men and women who have staked their careers on them. Is that data just tricking us? Is there something weird happening in the cosmos? What can help us understand questions like:
-
Why are stars flying away from us faster than we can explain?
-
Could impossible particles emerging from beneath the Antarctic ice be clues to a new subatomic world?
-
Why are fundamental particles of the universe behaving in that defy our current understanding?
I'm on at 8:00PM UK / 3PM ET, AMA!
