Just out of curiosity, given all the high-ouput motors, advanced materials, etc, is it actually possible to build a functioning ornithopter (flapping-wing aircraft)? I know we tried back before the Wright brothers, but is it possible now?

When someone says there is a "one in thirty thousand chance" of whatever, exactly how do "they" determine that number. For ex.: just taking the number of people in the U.S., and the chances of getting struck by lightening, if it storms in one small area of the country, huge clusters of people aren't going to all drop dead from getting struck. So on a larger scale who really knows the real percentage of anything so random and large. (And please, I am curious but explain it in real-people language! ;-) Hee Hee) Thanks!!

A car accelerates from rest with a constant positive acceleration of ax = +2 m/ss,
then brakes with a constant negative acceleration ax = −4 m/ss, coming to a stop after a
total time interval of 30 s has elapsed. What are the distance traveled and the maximum
velocity reached by the car? (b) What are the car’s average velocity and average acceleration
for this interval?

Orionid Meteor Shower
Could their be a massive meteor hiding in the current meter shower lasting until Oct. 20th ? Since the ancient Egyption pyramid and Sphinx alignment has been linked to Orion as being our ancestral planet, could the message now be a message of warning for Earth's destruction.Since we are destroying the planet and for the mis-use of our genetically given intellegence?

This is easy, yet most ppl dont get it......

A rich merchant had collected many rare gold coins. He did not want anybody to know about them. One day, one of his servants asked, "How many gold coins do you have, sir?"

He replied, "If I divide the coins into two unequal numbers, then 29 times the difference between the two numbers equals the difference between the squares of the two numbers."

How many does he have (this is too easy)
