Random Thoughts Part 5: Time to Split Again

[Sophia]

I ve just learned a new term "to be a shepard of cats". Used by a local politician who doesn't want to lead a coalition of uncontrollable and always arguing parties as a potential prime minister.
Just imagine trying to control a group of cats! That would be a great meme. :-D

 

[Psinter]

The "extra" day in a leap year. An informal term, I think.

Thanks.

Will we eventually run out of faces in our world population? I mean, consider two faces equal if individual eye, mouth, width etc. dimensions are each within, say, 1/4' of each other or less. We are 7 billion now, will the faces start eventually repeating?

A set of conditions to detect how both faces are equal will always be established in advance but to process a large of data input seems in-feasible so feature extraction i.e KPCA linearization is probably the way to go.

Do you know of algorithms for detecting moving objects? I want to put a set of cameras on my room with night vision and precise movement detection so that when something that is not me moves, the camera triggers an alarm to let me know that there's probably a spider in my room. Then I wake up, check the recordings and what triggered the alarm. I need to protect myself from spiders and that's the system I'm thinking of implementing. Then when someone asks me: "Why do you have so many cameras on your room?" I tell them: "It's classified."

Oh with such requirements, you will have more to lose than to gain then because what you need is actually a good insect repellent.

Sorry I don't know any that can detect a "mosquito" or a "fly" in a room .
But surveillance cameras can utilize this LOTS, for example.

Isn't there one every date that is divisible by 16, or is it every 4 years? Never mind, it is every 4 years.

You know, one place I've always wanted to go is Germany. There is one forest there that I want to visit, but I don't know it's name. I was told it was an astonishingly awesome forest. But I was only given a simple description that is not enough for me to identify it.

With roughly one third of the country being forest it's hard to tell. In some places they try to leave the forest as it is without human manipulations.

I sure hope the time never comes when I miss you... Nah, I'm sure I'm going to miss you yes or yes if the time ever comes when I cannot chat with you. But don't worry, I have everything 0.0000000001% controlled.

But if I can't chat with you I'll remember the times you made me laugh.

[Sophia]

Could it be area on the border near Czech Šumava national park? There are mountains like Alteklause and Resbachklause (this is most certainly wrong spelling. I think I never saw those names written down, it is just my memory of words I heard 5 years ago). They are famous because they leave the nature to evolve without any intervention. They didn't try to "save it" after natural disaster and now it can be used by scientists to observe uninterrupted natural mechanisms. It's very beautiful indeed.
There are hundreds of trees fallen down after strong winds and damaged by insects but below them, many young trees are growing and you can already see a promise of a healthy future forest. Meanwhile, the old rotten trees serve as a habitat for various kinds of animals and plants and they also create the right microclimate for the young ones.
It's evolution in real time.

My Dad apparently had one. Two or three times over the years he had colleagues come into his work saying that they'd hailed him in the street, only to find that it was some poor confused chap who just looked exactly like my Dad. They never met, though.

It's a freaky thing. I have never met a double, but I have run across pictures of guys who look exactly like me a couple times.

There have also been a lot of articles like this in the past couple years:

But I don't see how Gauss birthday falling on a Wednesday says anything to this effect.

You need to have a starting point. I guess any day will do. The only hint in the book reads: "This is less an exercise of induction than rather an exercise in systematic counting." Probably one has to derive a formula for friday 13ths first. See, why I didn't like it very much? But it's quick at hand to look up exact wording of definitions.

 

[JorisL]

But I don't see how Gauss birthday falling on a Wednesday says anything to this effect.

I suppose you just need an arbitrary starting point since it's an induction argument and we assume time to be continuous in a sense.

A quick googling suggested the days of the year repeat after 28 years.
Then the counting begins.

I understand; it might as well say Fresh_-42 (plus S&H) was born on Thursday May 1 , 1777, but I don't see how it helps you find the first Friday the 13th. If it had said, e.g., Fresh _-40 was born on Thursday September 12th 1778 or something.

But then you also have the mess of taking leap years into account. The "standard" non-leap year has 365 = 52(7)+1 days, so each date is shifted forward by one for every non-leap year and by 2 every leap year. And then you have 7 "types of years" , starting either Monday,..., Sunday, and then either is leap or non-leap. So there seem to be 14 "types of years", I am missing a factor of 2 somewhere.

 

[collinsmark]

Every 4 but not on a 100 except on a 400

Yes, and the leap year in 2000 was one of the special ones (one of the "divisible by 400" ones of the Gregorian calendar).

Did you know that the 13th of every month is more often a friday than any other weekday?

I had to look up a reference to that (I was almost ready to write another computer program to figure this out, but I'm satisfied with the reference). Here's the reference:
http://scienceworld.wolfram.com/astronomy/FridaytheThirteenth.html

Likelihood that the 13th will land on a given day of the week (over any 400 year period -- the Gregorian calendar is periodic in this respect):

Sunday: 14.31%
Monday: 14.27%
Tuesday: 14.27%
Wednesday: 14.31%
Thursday: 14.25%
Friday: 14.33%
Saturday: 14.25%
​

[Edit: If you are wondering what I mean by this 400 year "period", I mean that if you take any 400 year chunk of the Gregorian calendar, you will find that the months and days of the week line up exactly as the previous and/or the next 400 year chunk, assuming that the Gregorian calendar is still in place. For example, you can bet with 100% mathematical certainty that the year 2416 (i.e., 2016+400) will be a leap year and Feb 29th will be a Monday. Also, Feb. 29th will be a Monday in the years 2816, 3216, 3616, 2016 + 400n (where n is a natural number), etc.]

I didn't check the answers, my guess would've been the 400 years collinsmark quoted so now I'm getting confused.

Fortunately I have easier stuff to do to distract me from this before I spend a few hours on this.

No one remembers Arthur. I'm surprised you even know who he was.

No one remembers Arthur. I'm surprised you even know who he was.

The song was huge, though, back in the day:



Arthur he does as he pleases
All of his life, he's mastered choice
Deep in his heart, he's just, he's just a boy
Living his life one day at a time
He's showing himself a really good time
He's laughing about the way they want him to be

I also just remembered, that's the movie the line, "I'll alert the media," came from.

So that is an excess of Fridays of from 2/1000 's to 8/1000's , which is Strange, unless you make some sort of adjustments, since otherwise, every time one
has a Friday, a Saturday would follow.

But different lengths of months and leaps shift the days, since we only measure at the 13th.

How's that, how do you make that character Š in the keyboard? And how do you pronounce Czech? There are two consonants there together and I don't know how to deal with that. It, it confuses me.

Sadly I don't know . I wasn't given much details other than it was awesome. I was told it was really cold, but come on, it's Germany

. I'm used to a hot climate so by my standards all of Germany is cold (Source). 76°F and that's cold already for me. Obviously, because I'm used to a hot atmosphere, no matter the place I visit in Germany I'm going to feel it cold. So I cannot find it by temperature either.

Anyway the one you are telling me sounds cool as well.

Wow I couldn't stand hot climate! If it's above 30C (Google says that's 86F) I'm dying but believe me you would want to visit Germany in the summer because the difference between +25C and - 10C (14F) is quite big. You would feel the difference, trust me lol
What's the average temperature in your area? How much does it change throughout the year?
You asked about character Š. I use a keyboard that has these special characters so I just press the corresponding key. It's pronounced like English sh, the first sound in "show".
the pronunciation of Czech is similar to English word "check"

Don't worry, we are all used to our respective temperatures. Once in an apartment I couldn't control the air conditioner because the infra red receiver was broken (it wasn't me who broke it) and the AC turned on automatically every day at 6 PM. It dropped temperature to 20C (or so said the display) and it was really torturous for me. I forgot my thick blanket at home and I could only sleep like 3 hours or less every night. It was terrible. Almost two months went like that and it drove me really crazy. It was hurting me so much that there was a point when I couldn't resist it anymore and I cried that night . My spirit broke and while shivering at the 20C temperature and in the midst of crying I was saying to myself: "It's so cold . Why does this happen to me?" I cried very hurtfully.

What's the average temperature in your area? How much does it change throughout the year?

Meh, it's the same the whole freaking year. 90F is the average. Sometimes on the 86F-90F range and a lot of days go at 92F without changes throughout the day. Only at night it drops below 92F outside, but houses stay like that for hours and sometimes they get hotter (like 94F) as the walls push all the heat they accumulated during the day into the houses. Except for summer when it changes from hot to infernal... Volcanic infernal I'd say . It's only getting hotter as the years go by and that's a fact. I've never seen snow and I will never see it here. There's no such thing as winter, spring or whatever at my place. That's why I don't need spring to see flowers, I can see them the whole year long (in the nice forest). I think we only have two seasons: normal (hot) and summer (volcanic infernal) . Somewhat like this:

Spoiler

(But my place is not a desert.)

But I do still want to go to Germany, even if it's cold.

You're right, everyone is used to the temperature they live at.

But I would visit you (I'm joking of course) only for a short while otherwise I would be cooked alive.

Little birds yes, there are a lot. They are quite the colorful bunch . They are chirping outside as I write this. They stand in the windows and eat the insects that die or get stuck there at night. I've seen them too stealing the insects that spiders have in their webs. And if the spider is small and tries to do something (more like it doesn't escape on time) they eat the spider too . The smaller and more colorful ones eat small seeds and sugar from flowers (that sugar has a name, but I forgot how it is called... you know, the thing bees drink from flowers). And they fly very fast. Butterflies only deep in the forest. I used to see a lot of them when I was a kid, but they sort of disappeared. They appeared to have decided they don't like humans and secluded themselves deep in the forest. Far from humans. But I can still find them.

You have a gift of observation. Have you thought of using it for something creative or as a part of your job? I think you are very good at spotting details and describing things and you should definitely use that for some project!
Colourful birds must be so charming. We only have grey, brown or black ones. Only some have colourful tummies but not many. I'm afraid that butterflies are becoming extinct. Here too. My dad told me that there were many butterflies when he was little, they would chase and collect them but there are only a few nowadays. They don't like climate change and pesticides :-((( the same as bees! This troubles me a lot but I don't want to think about it because I will be upset. Sometimes I wake up at night and think about extinction of species and animal abuse and I get so upset and can't fall asleep again. And I know there's no way I can help them. I do my best to avoid all depressing news, documentaries and articles about this topic in order to forget about that.
No, 20 degrees is a very pleasant temperature for sleeping. In my area, most people consider it an ideal temperature. Not too hot , not too cold. There were winters when we had MINUS 20C (-4F) outside. Now that was cold :-) of course, there are central heating and insulated buildings to keep PLUS 20-25C inside during the day and we lower the heating a little bit for the night :-)
Random fact : extreme temperature changes are the reason why our roads are in a horrible condition. Well, in Germany and Austria they have similar weather yet their roads are perfect. Our politicians are better magicians. They are great at letting money disappear

What temperature do you consider very hot in your area?
