I feel like I was just nerd sniped, but this drove me crazy until I thought about it for a bit.
If we treat Earth's orbit as a perfect circle, then the number of milliseconds in a year would be its circumference. To get to pi then, we just need to divide that by its diameter or 2*its radius. In addition, we have the circumference in ms so we want to convert that into a distance or the radius into ms so we need the speed the Earth is rotating around the sun.
The average radius of the Earth to the Sun is 149,600,000 km so the diameter is 299,200,000 km. Earth's average orbital speed is 30 km/s or 0.03 km/ms. Combining these two numbers to get ms, (299,200,000 km / 0.03 km/ms) = 9,973,333,333.333 ms, which is very nearly 10 billion.
Would you be willing to share the alpha?
I've been a long time fan of wunderlist and just put a ton of things into it for an upcoming move. Kind of bummed it's being shut down and would love to try yours out.
I still use http://seductiveequations.com/2015/11/09/water-meter.html rather often to casually see how much water I've been using.
Helped me to discover when a new water timer I installed outside got stuck open. Similarly, I've been able to see through actual data how much water my new low-flow showerhead just saved me right after I step out of the shower.
Wish I had more time to improve it, but despite that, it's still remained quite useful.
Found this kind of interesting, but I'm having a hard time understanding the procedure. Do both people ask each other every question or does person A ask question 1, person B asks question 2, and so on and so forth?
