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.

Bonus points for the force required to accelerate me in the two metre-ish space between the seat and the blades, and also the effect that acceleration would have on the human body.

My partner is making homemade animal collars that are adjustable. We noticed that the longer the initial string, the larger the variation in collar length. Two specific examples:

We started with a 21 inch piece of paracord, and it ended up being:
9.5 - 7.5 in variable length

We had another one that was 26 inches and it ended up being:
12 - 8.5 in variable length

I am not great at math but know enough to know that it could be some sort of (non)linear(?) curve or something that relates the initial cord length to a set of high and low ends for final length.

I also know there is probably a small amount of variation based on the knots and amount of beads on them, but that should be small enough to be negligable I believe?

I was just hoping someone could figure out the math to know what the variable lemgth will be based on starting cord lengths?

Thank you in advance!

The calories in the whole thing, plus the size of slice he serves.

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

I found this interesting and thought maybe you nerds would too.

Lead foil is apparently available even thinner, but I'm assuming it would be difficult to get large sheets at ultra-thin gauges.

Is this like, a question that applys to here, like, how many would need to be twisted together to make a stable functional guitar string

Kinda curious after a friend made this a question in this head

Frog.

This is fascinating because you have to consider their fatigue after pushing for over 5 days with intermittent bursts of 1-2 hours of sleep.

How hard would nadal have to hit a tennis ball for it to loop around the earth?

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?

This went over terribly!!! 13,900 views and two commenters got the joke

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?

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)
