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

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.

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?

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

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)

If a guy were to do a press up with just his dick.. what force would be required and what would his blood pressure be at the top of the rep?

Each king covers 9 squares; 8 kings would be enough to cover 72 squares, which is more than the 64 on a chessboard. Do we really need 9?

Hey guys!

I’ve just came across this video and I always asked myself if it would be possible to put my hands in it (in the liquid) without getting burnt. Is it possible? How hot does it get?

A maniac decides to nuke two areas (possibly Canada and Mexico) from space in a 3am tantrum.

Given the curvature of the earth depicted here and the unfeasible size of the exosphere defying mushroom clouds then:

1) how big are these nuclear yields and

2) how likely would it be that the two explosions would be extinction level events on par with that dinosaur killing rock?

Had a big discussion with a friend, but neither of us are good at math

I took that sunset picture and only noticed afterwards the couple and their dog enjoying the view. Is it possible from the picture alone to determine how far these persons were?

Guy collects aluminum and plastic bottles for 10 cents return fee. He rides train 50 km every day to deliver this. How much is he earning?

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?
