Pfft! I knew the answer before it was even asked. I wanted to know how smart chipcom thinks he really is.

The weather here took another downturn so Chip may be out-of-sorts (as the limeys say).

More interesting to work out how long it is before the hands overlap again.

"More interesting to work out how long it is before the hands overlap again."

The limit of the series: 1 +1/12 +(1/12)^2 +(1/12)^3...... hours

= a little more than 1 hour 5 minutes and 27 seconds

Hey, I just thought of another way. Between 12 and 12, this happens 11 times, so it happens every 12/11 hours. I checked the math, it gives the same answer.

But how long does it take for the minute hand to lap the second hand, from your frame of reference, when it is on a spaceship traveling away from your at 95% of the speed of light?

I'm not sure, but I know it is past time for me to go to bed. G'nite!

But that doesn't tell you how long between the current time and the next overlap.

It's always the same. Think of the hands as two race cars going around a circular track, each at a constant speed, where one is twelve times faster than the other. It always works out to 1.091 hours ( 1:05:27)

When it is 3:15 in this room, it's typically about 70 degrees.

I'm not sure, but I know it is past time for me to go to bed. G'nite!
t' =t * sqr(1-v^2/c^2) = t * sqr(1 - (0.95^2/1^2)) = t*0.312

1.091 hours / 0.312 = 3.5 hours

I think this is right, but I wouldn't bet the house on it.

I see Chip hasn't replied to this thread. He must not have the answer. I couldn't have made it any easier for him, his name is in the freaking thread!

I wonder about that man.

Oh, I think what you are doing is awesome! Keep up the good work.

However, I'm beginning to think Chip doesn't know the answer. The man isn't right in the head.
