I needed this today; maybe it will help someone else.
humidity should be 0-100 temp_c is a float
l = Math.log(humidity / 100.0) m = 17.27 * temp_c n = 237.3 + temp_c b = (l + (m / n)) / 17.27 dewpoint_c = (237.3 * b) / (1 - b)
I just finished watching All or Nothing, a documentary that chronicles the Arizona Cardinals’ 2015 season in the NFL. From August to January we followed the ins and outs of each week, each game. In the end, though they were close to their goal, they lost the conference championship game. Their season was a failure.
Getting to Space is hard, but staying in Space? Well, that’s something altogether different.
Getting to Space is fun, and it’s relatively simple. Point your rocket up and burn until the stars come out. Then, you fall back down. It’s a thrill ride; an adrenaline-soaked shot to a dark sky. The view is phenomenal, sure, but it can’t last. What goes up, must come down.
Staying in Space is the Really Hard Work. You don’t just go up to the edge of the atmosphere, you need to go up to the edge of the atmosphere and be going 17,000 mph when you get there.
Getting to orbit is tremendously harder than going to a high altitude, but the payoff isn’t just one of magnitude, it’s one of kind. There are things you can do in orbit that you simply cannot do by jumping to the edge of space and falling back.
For those of us doing Knowledge work, the need for us to get above our worlds for extended periods of time is crucial to doing what we need to do.
These days it’s trendy to be pessimistic. Every time we sign into Facebook our friends (or moms) are telling us about how crime is up, incomes are down, morality is on the way out, Zika virus is about to infect us all, and if that doesn’t kill us, Islamic Terrorism definitely will.
