Random Thoughts Part 5: Time to Split Again

[collinsmark]

Let me make up a quick example of what a Boolean expression is. For the purpose of this post I'll spell everything out instead of using symbolic shorthand.

Below represents a single Boolean expression that I just made up now, but for clarity, I'll break it up into several smaller expressions:

A, B, D, and E are input variables:

C is true if both A and B are true.
F is true if either D or E is true.
G is true if both E and A are true.
H is true if either "A is true" or "F is not true", but not both (if both "A is true" and "F is not true" are true, H is false).

J is true if C is true, G is false, and H is true.

So here is a question you can use Boolean algebra to help solve:
If we have:
A: True
B: True
D: False
E: False

What is J (True or False)?

That's a very simple Boolean problem. They can get a lot more complicated. This was just for a simple example.

 

[1oldman2]

I see two.

That is what I count also.

 

[zoobyshoe]

Two is certainly the minimum number of different girls there could be.

name the 4 scientists left to right

According to my wife, anymore than one is big trouble.

 

[zoobyshoe]

name the 4 scientists left to right

I get to name them? O.K.: Larry, Moe, Curly, Shemp.

 

[collinsmark]

name the 4 scientists left to right

My guesses are

In order from left to right,

Albert Einstein
Isaac Newton
Charles Darwin
Nikola Tesla

 

[BornCane]

correct :)

the first 3 are pretty easy...but Tesla i thought would of been more tricky

 

[zoobyshoe]

Because Tesla seems to be holding a slim jim which has nothing to do with anything.

What the hell is that floppy stick thing supposed to be?

 

[zoobyshoe]

For consistency's sake, determine x in the following:

Apple:Newton = Scull:Darwin = x:Tesla

and

Apple:Newton = Scull:Darwin = x:Einstein

He has something like that in his other hand. I'm asking about the thing in his left hand (far right in the picture) that looks like the meaty snack treat, a Slim Jim.

Good question. My guess is a cane, like this one from a statue of him (statue is displayed in Niagara Falls). I guess he's holding the cane in the middle in the miniature figurine.

Plausible.

But, I think a cane would not be a proper icon-object for him the way Newton's Apple is for Newton. What would a proper icon-object for Tesla be? And for Einstein?

How many different girls are in this photo?

http://www.dailydot.com/lol/instagram-girls-mirror-photo-optical-illusion/?fb=dd

After much puzzlement, I think I found the answer.

Two, but the bracelets confuse me. I can't see the bracelet of the girl who is looking directly into the mirror.

 

[collinsmark]

Two, but the bracelets confuse me. I can't see the bracelet of the girl who is looking directly into the mirror.

It could be that the bracelets, in any given reflection, are ultimately hidden from view due to being blocked by another wrist (or two). Since each reflection can be characterized by having its own perspective and angle (relative to the camera), this seems plausible. I.e., in some reflections the bracelets are blocked from view, but not in others.

It's tough to tell just by eyeballing it though.

Spoiler

Without detailed analysis though, I would guess there are just two girls.

 

[rootone]

... I don't know what's wrong with holding hands. I think holding hands is awesome. That's a question for some men.

Not really, A handshake between men is a very common gesture indicating agreement.

Can't see how Lewis Carroll got a hold of a camera.

 

[rootone]

... it either be photoshopped ...

The background wall gets greener for the more distant girls which could be expected from multiple reflections through glass.
I don't think somebody 'shooping' would think about doing that.

Can't see how Lewis Carroll got a hold of a camera.

HG Wells did.

I think it's two sets of identical twins posed really carefully, but not perfectly. The fifth girl from the left seems to be looking right at the camera, while the first girl on the left is looking off to the left. The fifth is not a repetition of the first, therefore, but is the reflection of the fourth.

Notice that Girl #3 seems to be looking at the camera every time she repeats. That means both #2 and #3 were looking at the camera; #2 at a reflection of it, and #3 directly at it. However, girl #1 was looking to the left while girl #4 (her twin) was looking directly at a reflection of the camera.

Girl #6 has a cleft in her hair (look carefully) that can only be explained as a reflection of the back of the head of girl #3. The same cleft does not appear in the hair of girl #2.

That leads me to the random thought, "Is a CRT just a fancy lightbulb?"

The 5th from the left and the 1st are the same. Look at the piece of hair flying at the right of their heads making a circle. It's the same in both.

That's a dead giveaway that we cannot simply conclude that there are more than two actual girls.

Multiple reflections of the same girl looking at the camera would be an indication that her "reflections" are not reflections after all, but rather they are different girls, each of them looking at the camera, or that something was photoshoped. I don't see that here, regarding girl #1.

What I see is consistent with all her "reflections." In other words, if of all of the girl #1-like images were identical, it would be a dead giveaway that something was photoshoped, or there being more than one girl #1.

I see "girl #9" looking at the camera, which is really girl #1 looking at the reflection of the reflection of the reflection of the reflection of the camera. It only stands to reason that girl #1 would be looking to her right to see this fourth reflection of the camera.

Let's look at it one of girl #1's perspective. She is in a hall of mirrors and sees many reflections of the camera. She can stare at one of the camera reflections (or the actual camera itself). I think she is looking at the third leftmost camera that she sees, which is really just the reflection of the reflection of the reflection of the reflection of the actual camera.

• Leftmost camera is the actual camera (from her perspective).
• Second leftmost camera is the reflection of the refection of the actual camera (from her perspective).
• Third leftmost camera -- the one she is looking at -- is the reflection of the reflection of the reflection of the reflection of the actual camera (from her perspective).

Notice that Girl #3 seems to be looking at the camera every time she repeats. That means both #2 and #3 were looking at the camera; #2 at a reflection of it, and #3 directly at it. However, girl #1 was looking to the left while girl #4 (her twin) was looking directly at a reflection of the camera.

That normally would be a dead giveaway that there are more than just two girls: if, for a given girl, more than one reflection were both looking directly at the camera. But if you look carefully, there's more going on. Girl #2 has a very mild condition of esotropia, where one eye points inwards (this particular girl's right eye).

Girl #2's right eye is pointing slightly inwards. You can't see that directly from girl# 2 because her head is pointed away from the camera. But you can see it her reflection from "girl #3," which is really just the mirror image of girl #2.

In other words, I believe girl #2 is looking at the very first reflection of the camera. But her right eye is directed slightly inward, which we can see in girl #3, which is really the mirror image of girl#2. In subsequent reflections we cannot see her left eye (blocked by head of reflections of girl #1). So it may appear that girl #7 is looking at the camera, but I contend that it is merely a result of girl #2's esotropia (and girl #7 is merely a multiple reflection of girl #2).

-- By the way, for what it's worth, one of my foremost role-models throughout my life (since childhood even) has this condition. It is not unfamiliar to me.

Girl #6 has a cleft in her hair (look carefully) that can only be explained as a reflection of the back of the head of girl #3. The same cleft does not appear in the hair of girl #2.

Mmm, I don't see it. Perhaps this is really "girl #5"'s hair being confused with a tuft of hair from "girl #6"'s as the result of the different angle/perspective. (I'm not saying there is really a girl beyond girl #2; the rest are merely reflections that start to overlap each other more due to the change in perspective of reflections). I'll qualify that by I'm not sure what you are referring to in this cleft. But from what I see, I attribute what I think you might be referring to as simply being a result of the different angle/perspective enjoyed by the different reflection of the two girls.

So for now, I'm sticking with just two girls, and a couple of mirrors.

Wow, that's a very large post. Before I read it let me post this:

How many of you remember this plant from when you were kids? http://imgur.com/gallery/18ODwbx

I used to touch them and amaze myself at how they closed and after a time they were opened again. Although the ones from my place closed faster than the one in that video.

 

[Psinter]

No, it's not. Download the picture and zoom it.

 

[collinsmark]

No, it's not. Download the picture and zoom it.

I still don't see anything that cannot be explained by a difference in angle and perspective (consistent with a different reflection).

Similar to how a meteor (shooting star) might appear to be shooting across the sky -- sometimes away from the direction in which you are looking -- even though in some cases it is mostly moving toward you if you consider all three dimensions.

In girl #1 this tuft of hair is facing the camera, giving it the perception of "going down" quickly. But from a different angle/perspective (e.g., girl # 5), one realizes that it points outwards a little. Same girl, same tuft, different perspective.

 

[Psinter]

I still don't see anything that cannot be explained by a difference in angle and perspective (consistent with a different reflection).

But I needed something that wasn't angle or perspectives to notice it was only two. My mind is not very good with these things. If only they showed their teeth I could identify them better. Or maybe a spot in their faces.

You are not alone in this regard!

Although I don't see anything inconsistent with the picture being just two girls and two mirrors, it isn't obvious at a glance (not even to me).

This is a picture where I have to first look for something that at a glance might be inconsistent, and then rethink perspective and angles to check. For me, it takes a lot of thinking. I haven't found anything inconsistent thus far, but nothing was immediate.

Anyway, although I'm still sticking to simply two girls and a couple of mirrors for now, this conclusion was one that took a fair amount of staring and thinking. It wasn't a "gut" reaction.

Apparently, in the "woman in the red dress" scene in The Matrix, if you look carefully at the extras they were all made up of twins. The idea was that the guy who wrote the simulation got lazy and just cut and pasted a few characters...

How much do you usually tip at an average pizzeria or restaurant? Do you round your price at a supermarket to avoid carrying a wallet full of 1 and 2 cents? I've heard that in some Asian countries leaving a tip is considered rude and offensive whereas American waiters will ask you if there was a problem if you leave too small tip

 

[Psinter]

I leave whatever I have to leave to complete the next dollar bill. For instance, if it was $11 I just give them $20 and tell them to keep the change. And if it is $18 I give them $20. Whatever it is to complete the next bill.

EDIT: Ugh, my head hurts. I think I'm going to be out of service for a while.

I guess 10%-15% of the total payment.

Really? I don't know which one takes it as rudeness.
Maybe you should not get to such restaurants again. Those are clearly too impolite even though they live on tip based incomes.

I think it is a good lifestyle you have. When I go the pool, I offer them 5 when the ticket price is 3.5 and on some special occasions, I may offer them 3-5 more.
I watch couples fight, argue right in their families, you know all the words people use for each are awful. If you happen to marry one, first 10 years, you both may sound sweet to each other, later 20, things may get sour. There is really nothing worse than marrying a "calculator" who may be writing down everything you have used that is his/hers and later before divorce will ask you to pay back all of them.

Yeah, it totally depends on the culture how much you tip. It also depends on the type of pizzeria:

• Largest tip required in a restarant where someone takes your order at your table and also delivers your food to your table.
• Less if you order at an ordering station, then sit down, followed by somebody bringing the food to your table.
• Least (if any) if you are at a place where you both order and pick up your food away from your table.

Really? I don't know which one takes it as rudeness.

Japan for one.

Once I was eating a quick lunch at a restaurant in Japan -- an American themed restaurant at that -- and I left a small tip on the table before leaving. It would have been a slightly skimpy, yet not unreasonable tip by American standards. I was told not to tip in Japan, but being used to American tipping, and being in an American themed restaurant, after all, I didn't think much about it.

After walking about a block and half I looked behind me to see the waitress running towards me, yelling and waiving her arms to get my attention. I stopped as she ran up to me,
... "Sir, you left this on your table," she said smiling and a bit out of breath, as she attempted to hand me the tip from the table.
. ..."Oh, I left that for you," I said while showing reluctance to take the money, "as a tip."
.. ...At that point her smile morphed into dejection, and what I can only describe as some sort of sadness or disappointment. It was as though I had called her by an insult. There she stood though, her determination to return the tip unwavering while she failed to translate her thoughts into English. Her intention was quite clear to me though, and I realized well that had I not taken the tip back immediately, her disappointed face would have turned to one of anger and annoyance.
... So I took back the tip.

On the other hand, once I did tip a taxi cab driver in Japan, and he didn't seem to mind too terribly much. So there's that.

Tipping is definitely different in different cultures though. That's my main point.

Haha. Then I suppose is a good thing I don't expect to marry anyone.

Not really, I'm poor. I rarely go to pizzerias or restaurants. It's just that when I go I'm like: meh, forget about the change, just keep it. Perhaps it's out of laziness of waiting for the change.

I remember once I ate with some girls at a restaurant and while the service was horrible I didn't care and gave them the $20 bill. Each of us paid our own food (mine costed like $12), but only I left tip. The girls didn't like the service and left nothing for tip. As a matter of fact they were asked if they weren't going to leave any tip by the waitress and they slam dunked in the waitress face that the service was terrible . One of them told me: I can't believe you left them $20. And I told her: meh, I didn't want to wait for the change, it's too bothersome.
