The numbers don't add up

by Jesse 27. October 2008 23:21

A friend of mine got pulled over the other day, maybe a half mile behind me.  When I heard the officer gave him a ticket for 78mph, my first response was "no way in hell".  I'm good at math, so I decided to prove it with numbers.  Take notes, you can use this because its math.  Numbers don't lie (if you don't screw up).

Trig teaches us a couple useful things.  First, one of my favorite equations, A2 + B2 = C2 - this tells you the length of sides of a 90' triangle, C being the hypontenuse.  What does this give us?  Everything we need, IDDQD, I win.

When the officer was tagging people, he was outside the far RIGHT lane, not the usual left lane, being head-on with normal, would-be speeders -- this is a fault of the officer I intend to prove with simple math.  There's also a fundamental flaw in lasers - they ONLY measure the velocity of an object realitive to the device, a perfectly straight line (ok, maybe off by a degree or two, but thats neglegable) -- that's why most officers sit in the left side.  I'm going to first establish the area, and some measurements thanks in part to Live Maps.  These are estimates, but a lot safer than actually going out there and measuring Smile

5pm on I71 south bound on the north end is a bit of a mad-house and usually lasts until 6-6:30 (duh, normal rush hour).  People coming out of Polaris heading home, hitting 270/161/etc makes it a bit on the heavy side if you can't get out before 5.  I'd call it modertate traffic - you aren't changing lanes much and when you do, it might take a few seconds to get over.  Not exactly high-speed territory.  More over, the officer isn't going to get a good clean shot to someone that's floating down the highway in the left lane, especially during this time which doesn't play into his favor.

Here's the area.  The officer sits on the far right, he's in the left lane.  He estimates he was about 100yrds ("about a football field") when he got tagged, which considering the traffic volume, I'd say thats possible.  He also estimates he was going around 70, not 78.  Lanes of traffic in that area are about 30 yards wide.  We have our math.  So let's start with using a perfect triangle (which, as you can tell, its not, we'll get to that).

Using our simple math of 1002 + 302 = x2, our math comes out to 105 for X.  So how fast was he going realtive to the 100yard side?  Easy - 78mph / 105 = X / 100.  This number comes out to about 74mph which is a huge thing.  In Columbus (maybe even the entire state), 10 over is two points on your license, under that is only 1 point and that turns out to a difference on your insurance -- they frown on tickets.  Now you could argue he said he was 100 yards away from the officer, and you'd be right, but comes out to about the same, the lower end of 74mph.

But there's a problem.  The road curves off to the left (east) meaning it isn't 30 yards at the base of the triangle.  By my guess, conservatively, it's 50 yards.


 

 

1002 + 502 = X2 comes out to 111.  78 / 111 = X / 100 comes to ~70mph.  Hmm, that's barely over the limit.  And if you again say "well, he said 100 yards" -- comes out to 67.1mph so by my basic, easy math, from where the officer was and the speed he recorded it COULD be anywhere from 74mph to 67.1mph - granted, yes still technically speeding, but NOT 78mph. You could also argue the officer tried to line up the left lane with where he was, which is plasuable, BUT with the heavier traffic ...I don't think that's realisticly possible to aquire a car though the traffic of that volume.  Hmm, maybe I should send this off to mythbusters?

I haven't forgotten

by Jesse 11. September 2008 22:38

I thought long and hard about posting this up, mostly because it's deeply personal.  This morning I decided I would.  If you don't care, consider this your "not a tech post" warning.

9/11 did affect me, more so than others.  Years ago, while working at an oil change place and talked to an army specialist about what he did and "what it means to be American".  We talked about how my generation didn't have a huge ordeal like previous generations had and I made a comment that haunts me, even today, "I think it'll takes something big, HUGE to get my generation to wake up".  I hate the fact I was right.  I came across a site asking if the rememberance of 9/11 was forgotten by many and people have returned to their daily lives, to some capacity I agree, but the the comment I left, I realized that it wasn't a reply but more a poem of sorts, and I'm no poet. 

I haven't forgotten...
I haven't forgotten how people ignore truth ...even when its right in front of them, plain as day.
I haven't forgotten how some think life is a commodity.
I haven't forgotten how people believe a plane can't atomize when striking a well-built structure.
I haven't forgotten how my military friends WANT to go defend our freedom.
I haven't forgotten how some of them are not coming back.
I haven't forgotten how unrealistic people have become about our rights.
I haven't forgotten how to stand up for what is right.
I haven't forgotten how I felt 7 years ago.

and most importantly...
I haven't forgotten I'm still not afraid.  I am a citizen of the United States, not a subject to the world.

Ignored by Ohio State Rep, Dan Stewart, 25th District

by Jesse 12. August 2008 17:19

If you have no interest in politics at all, stop reading now and ignore.

I was part of city government for a while.  Not an elected official or anything but I was kinda higher up in the ranks.  I also was involved in a campaign, "support the peeples court!" (I'm AMAZED that site is still up!) and that was fun as well, which takes me to my next issue...ignoring your constituents, which is a fancy way of saying citizens you represent, is really dumb.  Ignoring the ones that are motivated, with blogs, is even worse.

Recently in Ohio, a certain bill was put up, voted on and passed that was very common sense (yes, I read the bill).  I went to review how MY rep voted and was personally offended to find out he voted NO.  Being a curious person, I genuinely wanted to know why, maybe there's something I missed?  I NEVER RECIEVED A REPLY, at all, ever.  He could've literally drove down the street and made a personal visit but I guess he's too busy.  This is overly annoying and downright offensive ...not for the lack of a visit but the lack of a simple email reply.  For verification, here's my email, minus my home address, copy, paste.

from: Jesse Riley
to: district25@ohr.state.oh.us

date: Thu, May 29, 2008 at 2:11 PM
subject: Vote on SB184
mailed-bygmail.com 

Representative Stewart:
 
I just happened to come across the vote for SB184 and was somewhat surprised by your vote.  On paper, 184 (also dubbed "Castle Doctrine") seems to make a lot of sense, your nay vote cast raises questions -- maybe I'm missing something from this bill or a pitfall somewhere that the 23 nay votes might foresee a problem?  Can you please explain your vote?
 
Jesse Riley

I know for an absolute fact gmail addresses get though their servers.  I also know for an absolute fact they have interns to check these emails.  I hope that at some point Dan Stewart finds this and gives me an answer.  Otherwise, I'm still waiting and I've given you MORE than enough time.  (Honestly I don't expect a reply)

60 Second Science

by Jesse 14. May 2008 04:15

Ever since I got my zune, I've subscribed to all kinds of podcasts, one I particularlly enjoy is the 60 second science from Scientific American.  It's good stuff and REALLY lasts 60 seconds (with intro and junk, 1:15).  One that really caught my attention was one regarding Training Scientists to Run for Office.  It's an awesome idea and here's the transcript...

[The following is an exact transcript of this podcast.]

Would America be a better place if more people with science training held elective office?  One organization that thinks so is Scientists and Engineers for America, or SEA.  On May 10th, they’re holding a daylong workshop in Washington, D.C., to teach researchers the nuts and bolts of running for office.  More than 70 attendees have signed up.
 
SEA points out that understanding a lot of today’s most pressing challenges requires a science background. Energy, health care, climate, even general competitiveness are all deeply connected to scientific research and progress.  Even more important may be the general intellectual approach that scientists could bring. The group’s director, Lesley Stone, says, “Scientists and engineers have an appreciation for the kind of evidence-based decision making necessary for tackling our nation’s most pressing problems.”

something very disturbing

by Jesse 1. March 2008 16:04

For those of you who don't know me very well, over the past few years I have come to appreciate the right to bear arms.  I had a friend of mine who grew up with them teach me how to clean them, how to shoot them, how to handle them propertly, how to "check a weapon", shoot safely (I'm not the best shot though...) etc.  I learned how to do things by the book since it -IS- a clearly dangerous device.  Today while at a gun shop, I witnessed something that made me VERY uneasy.  A little background, this place I was at is NOT a dive, not shady, not on any level a place you couldn't take anyone.  It's a general hunting/fishing place.  Also another disclaimer, if you don't care about any of the following topics, ignore this post - guns, laws, government, politics.  Still reading?  Good, I think you'll find this interesting.

In order to obtain a firearm, a background check must be done, and they check for the obvious stuff -- no felony convictions, no mental problems, no domestic violence cases outstanding, no illegal drug use, etc.  This can be done VERY quickly, usually within a few minutes with a call in to the feds.  I use to work closely with the "other end" of law enforcement with my time at the Attorney's Office and I was lucky enough to understand and detect (although this isn't rocket science) those that are under the influence of various controlled substences (crack/cocaine, LSD, X, marijuana, etc) and immediately noticed that one such symptom was being broadcasted by someone across the counter.  No, I'm not kidding, at all.

The person in question had bloodshot eyes, pupils the size of golfballs and slightly ...I wouldn't say frantic but very "switchy" -- he'd been doing crack/cocaine at best 24 hrs ago (probably earlier that morning).  I watched this guy intently, listening to his conversation.  He says his son had taken his other gun, got arrested (hu?) and the police took it and wouldn't give it back until he proved it was purchased legally.  Ok, at this point, if EVERY SINGLE red flag in your head isn't goin off, I can't help you.  He then explains to the clerk, and I can't believe this, that he was serious about buying another gun as well as getting his proof of purchase.  The guy behind the counter showed him a good, well made weapon, at a cost around 600$.  If you've ever looked, 600-800 is right around what you'd expect for a good, quality gun (in this case a brand new Beretta 92 9mm) -- I paid 600 for my first gun (not a Beretta), USED -- he didn't want that.  Then he was shown another, a nice Glock with a price tag around 500-550.  He didn't want that either.  The ...um, clerk pulls out the cheaper gun (I'll refrain from saying what kind, I don't like 'em, I think they're crap) for 350 in a 9mm.  He was more interested. 

Now mind you, during this entire exchange, the clerk is NOT handing the person the gun, at all, he WILL NOT let him touch it which is a clear indication that he (the clerk) has noticed "somethin' aint right" -- every time I, joe citizen, go in and ask to see one, I am presented the piece, regardless of cost, checked (verified no bullets in the gun) and handed over as if it were a priceless piece of jewlery, typically with some discussion of the given clerk's experience or the other clerks in general, safety features, etc.

At this point, I'm very much "not cool" with this particular person.  Even idiot me can pick up this guy is on something and the questionare you MUST fill out asks specifically if you have used something he clearly has (which is a felony!).  I motion one of the other clerks over and express my concern.  Almost unbelieveably, he says "Oh I know, happens all the time, but we can't stop them from buying any gun they want, it's their right just as much as it is yours, and we aren't cops -- we just can't do anything about it, we'd get the pants sued off of us".

-long pause-

<Sigh> He's right.  So on monday I'm thinkin' I need to make a few phone calls, most noteably my friend thats a judge, see what she thinks.  I know there's some circumstances where this guy could've had a good reason for it.  Regardless, I, joe citizen, don't completely believe he'd be honest on that questionare.

** Update ** 4/13/2008

Got a comment on my blog from "The F.B.I." with the address given of info@fbi.gov but there's a problem with it -- 1, the IP comes back to France ...sorry, that doesn't make me feel its more authentic (using the onion aren't ya?), 2nd, it refers to internet crime and not ...um, real crime so for now, I'm going to leave it in the comment bin until I get a bit more info on this.  So if you're reading this, use the contact page (link's up top) and drop me a line, let's talk.
