Math During Sleep
I am definitely someone who has his unconscious mind working on all kinds of bullshit. Sometimes the truth of some event that happened decades ago will come to me, perhaps something about it I was trying to deny or suppress and that got hashed out; or perhaps due to being older and wiser the truth comes to me. Sometimes I wake up in the middle of the night with this.Or sometimes it's less profound. Like what came to me last night.
I had been ticked at myself for being unable to figure out how fast the lady was falling when someone tried to catch her. See the post in this thread,
http://wizardofvegas.com/forum/off-topic/off-topic/15842-man-fell-from-upper-deck-of-ralph-wilson-stadium-is-banned/2/#post293107
Now, this same thread earlier led to the Wizard working out some Calculus in an "ask the Wizard"
http://wizardofodds.com/ask-the-wizard/274/
And, I can tell you that one of the things I believe about Calculus is that in itself, it is not difficult [but see the PS below]; I realized this after reading or hearing someone say what makes Calculus difficult is the Algebra. In fact after hearing this it struck me that typically a math course shoots past the simple applications right away. In fact, working out answers to 'falling object' questions is a good example of simple application.
So I knew that knowing that gravity makes an object on earth fall at a rate of 32.1740 feet per second squared should tell a person quickly how fast they were falling after so many feet or so many seconds. The give-away is that this can be expressed also as 32.174 ft per second, per second. But I was stumped right away knowing that I had to solve for 45 feet, and I didn't know how many seconds. I was really pissed because I *used* to be able to do this! I pondered and pondered, sometimes on paper. I was determined *not* to look at the "ask the W" until I figured this out.
Last night, waking me up, it came to me. [it was slightly wrong, corrected now I hope]. Here is math from someone limited; I take a verbal approach to math, alas.
You have to ask, what computation of the formula results in 45 feet? G= the rate, S = time in seconds.
G/2 * S^2 = feet! As finally remembered, you have to take the average speed, not final speed, to calculate distance traveled. Solve for 45 feet.
32.174/2 * S^2 = 45
or
16.087 * S^2 = 45
S = sqrt(45/16.087)= 1.6725100110476963
double check, 16.087 *1.6725100110476963^2 = 45 , it checks
OK, what I am really after is final velocity of that person after 45 feet of fall
after 1.67 seconds at 32.174 feet per second per second = 53.73 feet per second final velocity.
At this point I have some rules of thumb about ft or yds per second so I can relate to the speed in miles per hour. Roughly 54 feet per second which is 18 yards per second,
roughly 36 miles per hour.
Let's double-check this too; "per second per second" is naturally confusing, but if speed is indicated differently, it clears up. It's about 22 miles per hour per second; that is less confusing. 1.67 * 22 = 36.74 mph approx. I think we're good (but watch somebody correct me again [g])
No, I ain't catching that woman!
>>>
PRESERVED INCORRECT MATH
G * X^2 = feet! So simple. Solve for 45 feet.
[the above statement is in error, correct formula is G/2*X^2=45]
[I got roughly 26 miles per hour, but the distance allowed a much higher final velocity]
>>>
PS: ANOTHER THING
I went to Wikipedia etc. and found no evidence whatsoever that Calculus isn't damn tough. Somebody makes it hard with algebra? Dunno. Maybe I have to take it back, nothing I look at resembles the Calculus for beginners I remember.
And check this out, I put a formula into an online calculator but then realized I had jumped the gun. Curious, I clicked on the "eguals" button anyway. Look at this weird stuff that came up. Is there not something perverse about where the math guys always want to go? You tell me!

Claiming Copyright!
Craps at the Greenbrier [WV] recently has been my only gambling lately; Harrington, Del, with what that casino was comping me, had me going once a month, but after moving to our new home that option is no longer practical. I am still not sure I would want to do Charles Town WV, not exactly close and not exactly trying hard enough to earn anybody's action. It thus has been May since I did any gambling.My old gambling problem has returned: I don't gamble enough!
So I put in some time at the G. and got 3 Craps sessions in; also a short BJ session. I was eager to try something. I just recently picked up some advice and it finally sank in that the "flying V" was not what I thought. I had noticed that set got some discussion, but when I looked up what it was about on some other website, the page failed to indicate much of interest. To my embarrassment, I also have to admit I failed to notice on any of my own investigation to find any similarly theoretically effective set assuming the shooter can keep the dice on axis for any percentage of the time greater than random. On the other hand, the Wizard also does not cover this set with his WoO page. I thank again the person here who clued me in; I'm guessing though he wants no citation.
The Flying V is a quick way of setting the dice with the assurance that the shooter will *not* have the same pair on the axis. Checking this out as I was advised, I found this does mean less 7s as a percentage should the shooter be able in fact to pull off an on-axis throw. "Correlation" effect can be random.
Further investigation showed that keeping both dice with 3-4 on axis in a throw increases the number of 7s and Yo's assuming "correlation" is random. As can be seen, the 5 and 6 both stay possible should the dice stay on axis. This "Yo Set" has got to be the set for the Come-out. I can't find squat on it on the internet and hereby copyright it! Anytime you talk about the Yo Set you must give me some dap! [vbg]
After this investigation I was good to go! At this point I should point out I absolutely have had no evidence before that I have been able to influence the dice! And you will be thrilled to hear that this time around I was clearly one of the worst shooters at the table!
In defense of my attempts, the table was plenty occupied and sometimes quite crowded, automatically meaning insufficient data on my own throws. Furthermore, I have no skill at doing what I am attempting to do, which is to lean out over Stick [being next to him] as much as possible and throw the dice gently, having them land and hit the back wall below the pyramids with as little energy as possible. I failed at this most of the time, and when I could do it, it was hard to claim good results. However, whenever I *knew* I had a bad throw when I released, it was 7-out!
The gambling was fun though, by the time it was all said and done I was only down approximately what I had left in tips. Can't beat that for cheap entertainment, which, friends and neighbors, is all it is to me.

Hello World, Goodbye Harrington?
Hello World, Goodbye Columbus Harrington!I guess I was surprised in the first place that Harrington DE got much of my action. I mean, the place is OK, very nice people there; the games are competitive in terms of rules too, such as 10x Craps odds. But the trip is just a bit too far, a "bridge too far" too as you have to cross the Bay Bridge and risk nightmarish backups. So, I expected the occasional trip maybe, when I knew the bridge would be OK. But then they started sending some fairly nice offers, offers that clearly would on average cost them with a player like me [the average player maybe not]. But I couldnt say no to the offers, modest in some terms, generous though compared to what my play should earn. I did go and It was fun.
Last trip was a repeat of the coupons doing fairly well, the Craps sessions not so much. I have to say overall the Craps table got the best of me - the variance was unkind. I sort of hate the idea of saying goodbye as I think I could at least pull up even with these offerings continuing.
Now though, I am going to be moving. It'll be closer to The Greenbrier in WV, but that is not the place to do regular gambling trips. Folks, it looks like I am going to be checking out Charles Town WV once in a while. It'll be a similar trip to what I was doing to go to Harrington, but without the bridge! Alas, all previous experience with the place has not been good. I'd even say it might be Hello World, Goodbye Gambling Much ... except I think we all know the siren call will probably prevail!
We shall see what we shall see. I'll miss those trips to the H.

I hope you have a good move and enjoy your new town. Wheeling Island Racetrack and Casino only offers 2x Odds, but if you'll ever be in Northern WV, shoot me a PM and I'll check my schedule.

Blogpost just for the record:Last gambling activity 4/17/13 Harrington DE with the coupons and free chow, see other posts. BTW this same deal came in the mail so it is on for May as well. A repeat of last trip, lucky with the coupons but not so much with the craps so wound up down a bit.
Most interesting event: while playing the Free Ace, which won for $100, I naturally decided to play out the shoe. At one point the guy at 3rd base repeats about 3 times "that's a King under that 5" [dealer had a 5]. Such information did not affect my hand, but I didn't know whether to believe him or not, he was kind of goofy. Sure enough it was a King. The guy stayed a bit longer than my 'play out the shoe' but I noticed him leave soon too. So, here was a guy in a sweet situation who didn't know to keep it to himself and profit. Observing, there seemed to be quite a few new BJ dealers from things that were going on. The pit boss had fires to put out all over the place and had to help certain dealers do the payoffs right if something got complicated.
I was silently critical of the guy who didn't know to keep his mouth shut, but after thinking about it later, nor did I note who the dealer was or try to stick around and see if I could get into a good situation myself. Paigowdan must be proud of me, I can honestly say I had little taste for pursuing it. I think it can be said, though, that I have largely gotten to dislike BJ and that was a bigger influence than anything else. And, just for the record, my luck in double-downs continues to stink. [g]
PS: heading to the H tomorrow 5/1/13. Definitely feel like it's going to be at least one session of darkside 10x odds. Might be busy, if so that will give me a handle on how many are there 'cuz of similar comps.

Diabolical Dastardly Darkside Dunk Defeats Dazzling Deal
Happened again.I can't seem to learn my lesson with the e-craps at Md Live. Wednesday I am checking out the early morning scene. Craps tables look like they are going to be available 24/7 at the joint but for now at least minimums are a killer. I was expecting that, so sought out the e-craps instead, might as well play a bit. Sure enough $5 minimum is available. I always play the darkside with the e-craps since there is a certain degree of privacy and I like the idea there should be fewer losing streaks on darkly winning your points. But the 3 or so times I've been there and let the dice "roll" enough times to win or lose a bit of money it has gone the same way, disaster! I am totally snakebit now!
It was typical on how the darkside gets me there. The history on 7 shows fewer 7s than average [which I trust since it is auto-posted]. First thing that happens is 7-winner [darkside loser] grrrrr. Then I'm winning the next couple of bets, 7-out [darkside winners with odds]. The next point is a 6 and I make a DC bet and another point is to be resolved. This is supposed to be a nice situation! Why not another DC? As long as points are to be resolved, it's just loading up the gun with bets that I am now favored to win! Sure enough I've got about 5 going, I've loaded a dazzling deal! It's noticeable now, though, that the machine can't seem to roll a 7. I lay off any more betting for a bit, but after a couple of my bets get knocked off, I do the DC again and replace one or two. But that 7 won't come! The history is now showing it's the longest roll in the history [ although pretty sure that is a very limited history... still!] Diabolically each and every bet gets knocked off as I watch, now too miffed to replace them. To add insult to injury, a 6 is finally rolled to lose the line bet too. All my bets are gone! I am down $150 in no time flat.
The most perverse thing? The history shows only three 7s were rolled and of course one of them was 7-winner taking out one of my line bets!
I can't seem to learn my lesson with the e-craps at Md Live Lesson learned. No more perverse e-craps at Md Live.

Heh. I guess that's called "losing." :) Seriously, better luck.

I'm pretty sure someone else at the machine was influencing the e-dice. You have to know who you're e-playing against. :)

stop looking at the stats board! it'll drive u crazy.
i learned. i even made a thread about it: http://wizardofvegas.com/forum/gambling/craps/13070-i-gotta-ignore-the-stats-board/
i'm up a little since Md Live opened and play twice a month on avg. I only play e-Craps and mostly Dark.
sorry to hear about your luck :(

Nothing worse than sitting there, looking at a big stack of chips on various DC numbers, and knowing that you have the best of it, while slowly but surely each one of them is picked off...

Something to be said about 'not playing scared' but my heart just isn't in with e-craps.

I can't stand e-craps...nothing about heart, I just don't enjoy it as much. I understand if you like the low limits and exact payouts on smaller bets, but that's never an issue for me. I just love the social interaction at the table, whether I'm playing light side or dark...if light side, all the general shit-shooting with other players and dealers, sharing in the joy of a big win, or commiserating about a loss. If dark side, the subtlety of not celebrating and trying to nonchalantly pick up a big stack of chips after the shooter set up about 4 numbers and then hit the big red...
Anyway, none of that at an e-craps table. I guess the celebrating together part maybe, but it's much subdued in my experience.

Unfortunately, the real equation is G * X^2 / 2 = feet. That's the problem with unit manipulation. It's easy to miss constants. Otherwise, I think everything you did should work out ok.
I walked away and realized it was wrong ... couldn't get back to the keyboard
What do they call it in calculus? the first derivative? somesuch.
In plain terms, the object starts it's descent at zero miles per hour, thus you can't use the final velocity like it was in effect all along. Divide by 2 and you have the average velocity.
I am going to attempt to fix this.
Exactly right. Acceleration is constant, velocity is linearly increasing, position can be obtained from average velocity, which is (zero plus final velocity)/2.
corrected now I think
Ain't catching her?
The mind is funny. I doubt you'd even have a chance to think, should that happen in your presense. It's a reaction, just like the old thread about the hot air balloon and if you'd let go. No time to ponder, to time to compute. Just "do or do not".
But put into persepective, even a goon can hit 20mph on skates. Some of the real speedsters can hit 35mph, no problem. I'm sure I personally could crack 30. Just about every check you see in hockey is a worse hit than that little woman would put on you.
Just wanted to add some perspective, in case it rains women aorund you in the future. You might save someone's life and suffer little more than the pain of a check.
>Ain't catching her?
I feel shame now
OK, at 45 feet I try to save her, but at 55 feet no way! [solve for final velocity for me btw][g]
No shame, just perspective. You see someone fall on someone else from height, and it looks kind of devastating. But then you realize the forces involved are more common than you might intuit, forces which you see over and over and over again on any given Sunday. When it comes to possibly saving someone's life...wouldn't you do it now, knowing it's no worse than Face losing control and running into you on the ice?
As for the math...how about "no"? =D AZD will become a bleeding heart before I understand anything above 8th grade math.
What I find hilarious about dreams is if you directly question the people in your dreams about the facts of your dreams, they change the subject hoping you'll forget your objections and normally they're right.
