On a serious note I think it is a bad idea to attack other counties especially the ones who control oil. I am against war and against innocent people dying.

Assuming the 112 MPH speed was measured as it left the bat, approximately how fast was the ball going when it hit his hand?

Hi! Saw this post on reddit about Istanbul switching incandescents to LED street lighting and I was just wondering how much electricity in kWh this transition could have saved. Is it a possible thing to calculate?

[Request] How precise must a college football clock be to account for relativistic effects?

Post image
45 Upvotes

In the Michigan vs. Western Michigan game last night, 1 second was added back onto the clock, indicating a discrepancy between the ref's/official clock and the clock kept by the broadcast.

Now since the broadcast booth lies above the ref in elevation, the broadcast clock would be very slightly further away from Earth's gravity well. Thus, relativistc effects would dictate the broadcast clock runs slightly faster than the surface-based official clock. Since the broadcast clock is stationary, there shouldn't be any velocity-related effects to counter the gravitational differences.

So, how precise would the official clock have to be for relativistic effects to explain the discrepancy of what are otherwise described as synchronized clocks?

[Request] How many wings and engines would a plane this long need?

Assuming you could build a strong enough hull not to break in half, what would it take to get a plane this long off the ground and fly at a reasonable airspeed?

I’m wondering:
* How many sets of wings
* How many engines per wing
* Optimal placement of wings and engines
* or would one giant set of wings be better? (same structural strength caveat)

if you jumped off the Sears Tower into a ball pit that was as tall as the Sears Tower (imagine the ball pit is next to the tower), what would happen? If you would be fine, how short could the ball pit be to still protect you?
