What in the hell is that, right?
Well, if you’re young, smart and more driven to succeed than I was, hit the books son and learn how to read, write and apply that tier of math because the world will be needing people like you more and more over time, and they’ll pay you too. Cash money.
So that formula is the Okumura-Hata model to predict the total path loss along a link of terrestrial microwave and other types of cellular communications in a medium-sized city. It’s one of many mathematical gems used by engineers to calculate the real-world size of a cell created by a tower in an urban area.
The information yielded is helpful to know when planning where to place cell towers when wiring up a city for wireless communications. Much work was put into coming up with it and its application is very practical indeed, not just academic.
We’re not calculating the circumference of a circle for the hell of it anymore. This is all about doing more with a finite resource. This isn’t a game; this is real life kiddo. Wake up.
History has shown that over time more people tend to be alive simultaneously and using one or more mobile devices. Over time more white cops shoot black kids, and those people congregate into already-densely populated areas, livestreaming the chaos from their phones to phones of others.
In order for livestreaming the looting and arson to go smoothly, people need to be able to communicate. So cellular carriers are desperate not just for more spectrum from the government but for better math to plan tower distribution and to devise protocols, like LTE Advanced, that can support twice as many protestors in a given cell sector than your daddy’s clunky old LTE protocol (I’m talkin’ system spectral efficiency from dynamic radio resource management — google it).
Too long; didn’t read? Math, unlike Latin, is worth studying. So is calligraphy.
Also, that cop’s innocent, get over it.

Biographical info.. hmm. I have a history of not being able to strike the balance between what is "safe" to put into these forms and what is, in my mind at least, funny. Can't do it.
Very nice article Simmons. I actually had to write calligraphy in high school and remember hating it. BTW, the cop resigned today.
That’s pretty clever, how you manage to convey your displeasure with someone’s poor or otherwise undesirable, or underwhelming, recent performance by merely offering a compliment when the opportunity finally strikes.
Though he came off sounding like he was attempting in vane to quell impending unrest, I think that that prosecutor when giving that long speech wrapped around the grand jury revelation intended to cement this as a termination to any other avenues of legal pursuit against the cop (federal, civil).
I have a theory that one of the factors in his consideration of going the middle of the road route, longer and with a flood of evidence, was to protract the process in order to delay the obviously predictable and racially-incendiary decision into the winter as the cold would, and most likely did, greatly dampen what would otherwise be a much nastier snafu. I had a second weather widget on my phone home screen for the temperature in Ferguson for the past few months.
I cannot believe the nytimes published the cop’s address earlier in the month.
Anyway, thanks. Weird, I wrote this article very differently and from scratch three times, this version being the fastest, shortest and of the least research. I’m just no damn good at time management. Or math.

You took me back to past.
Thanks again.
