I’ve decided to start a collection of logic puzzle videos after completing the great Professor Layton and the Diabolical Box DS game. I’ll add a WLP (Weekly Logic Puzzle) every Monday. These puzzles only require thinking, and there shouldn’t be a need for any outside knowledge about the puzzle. The puzzles will have small modifications to other logic puzzles I already know, making this a unique collection.Introducing Yubotu Logic Puzzles
This video introduces you to a logic puzzle called Yubotu (or Battleship Puzzle). Runs through solving an entire easy puzzle.

Do the brain games actually help your brain function?
i was checking out some of the brain games on the ipod. I think they’re pretty fun, but do thry actually help your brain?
The right kind of brain training exercises can improve cognitive function, delay cognitive decline, and improve performance on everyday tasks.
Cognitive training has been shown to have positive benefits that extend beyond improvements on the trained exercises. In children, improvements in visual memory and response inhibition have been demonstrated after visual working memory training (Klingberg, et al., 2005). Increased levels of activation in the prefrontal and parietal cortices were seen in children following similar visual working memory training (Olesen, et al., 2004). Improved mathematical reasoning performance has been observed following this training, as well (Holmes, et al., 2009). In young adults, a challenging working-memory task was demonstrated to improve performance on tests of fluid intelligence (Jaeggi, et al., 2008). Training on speed of processing and reasoning tasks has been shown to generalize to slowed declines in instrumental activities of daily living (IADLs) five years after training ceases in normal, healthy older adults (Willis, et al., 2006). Auditory-based cognitive training has been shown to improve memory for untrained auditory memory tasks, also in normal, healthy older adults. Participants in this study also self-reported improvements in cognitive function (Smith, et al., 2009). In fact, the evidence for the efficacy of cognitive training is so strong that an NIH-funded study prepared for the US Department of Health and Human Services agency indicated that cognitive training was the only type of intervention for which there is a high degree of evidence supporting a claim of reducing the risk of cognitive decline (Williams, et al., 2010).

I need someone to show me how to AND the answer to numbers 1,3,and7 (1&3 is first link) (7 is last link)
please give answer and tell how ypu got it and your method of finding it, basicallly all the info you can, THANKS!!

x=1
Think about it. If the 4 factors were just x’s, the problem would be x times itself 4 times (i.e. x times x times x times x), and the answer would be 120. So, x can’t be too large a number. For example if x =2, then 2x2x2x2 would equal 16.
Make x just a bit bigger, like 4, and x to the 4th power (another way of saying x times x times x times x) would equal 256. Way more than 120! More than double!
So x has to be less than 4, because you’re going to add 1 more to it each time you multiply x. So, if x=1, then you multiply it by x+1 or 2, and so on. So, if you forget about the x, and just think of multiplying 4 numbers in a row, each one 1 more than the one after it it, like 2x3x4x5, you’d get 2×3 =6 4×5=20, then 6 x 20=120. hey, that works perfectly. So, you know your 4 factors. X will turn out to be 1, because you need to subtract what you added to x to get any factor. So, for example, if the first factor is x+1 and it equals 2, then 2-1 = 1. x=1.
Does that make sense?
Why do I like math and solving logic puzzles, but dislike science courses?
People always say if you like math, then you also like science. It’s weird because I enjoy science courses like physics and astronomy. But I find courses such as biology and botany to be unchallenging and boring, and some parts of chemistry too, although not all of it. It seems as though all I’m doing in these courses is just memorizing random or bits and bits of information. Is it possible to like math, but not like science?
It’s funny because I am pretty much the opposite. I love bio<3. I like the other sciences too, but no where near as much as anything pertaining to the study of life.
It’s okay though, you just don’t fit the general description. You like what you like, and that’s fine.
Nostradamus Predictions: The Secret Code – Part 1/3
In May 2005, the Italian National Library in Rome made an amazing discovery. Buried in their archives was an unknown manuscript written by the famed prophet Michel de Nostradame, or Nostradamus (1503-1566). This manuscript was handed down to his son and later donated to Pope Urban VIII. It did not surface again until now, almost four hundred years later.
Using cutting-edge data mining techniques, Dr. Rathford sifted this complex word puzzle searching for significant patterns and relationships. Almost immediately, he came up with the predictive model known as The Nostradamus Code.
When the prophecies-within-prophecies are deciphered, the hidden timeline of World War III is revealed.

How good are you with logic problems – part 2.?
The residents of the country of Reflectia have a strange custom. No one is allowed to see a reflection of himself. They therefore don’t know the color of their own eyes and it is against tradition to tell someone what their eye color is. One day in the senior logic class the teacher announced that there was at least one student with hazel eyes in the class. I will let you think about it all day and first thing tomorrow you will let me know if you have hazel eyes. If no one knows we will wait another day.
Now if we know that there are 10 students with hazel eyes, how long will it take the students to figure out if they have hazel eyes, and how did they figure it out? The students themselves do not know that there are 10. Only you know that. If they look around and see 9 they still don’t immediately know if there are 9 or 10 (including maybe themselves)
Original question deleted due to lack of clarity.
Unless you have a very logical mind you will not figure this out. There is no simple or obvious answer.
No one may discuss another person’s eye color with anyone. They may only state what their eye color is.
Brian M is correct. I will give the best answer tomorrow morning.
10 days.
To solve this, I have to make the assumption that the other students in my class are as intelligent as I am (or more so)
Assuming I have hazel eyes: I would look around and if I saw noone with hazel I eyes, I would know it was me on day 1.
If I saw one person with hazel eyes, then I would not know on day 1, but if the person with hazel eyes saw noone with hazel eyes (including me) then he would know that he was the only one and would respond as such. If the person did not respond on day 1, then that means that I have hazel eyes, and I could respond as such on day 2 and so could he.
Continuing the logic:
If there are 3 people with hazel eyes and I am one of them:
On day one I would not know and neither would they.
On day two I would not know and neither would they, but from the logic previously learned about a case where 2 students are hazels we would know that there are 3 students.
On day three we would know that we are all hazels.
I believe that by following this procedure, we would all know whether or not we had hazel eyes after ten days.
Question about critical thinking/human relationship problems?
we see dark clouds and infer rain. We hear the door slam and infer someone has arrived. We see a frowning face and infer the person is angry. Our friend is late and we infer she is being inconsiderate. This sounds simple to me, but apparently there’s a lot of people that just don,t get it, my questions is…..the root of an argument sometimes is just plain miss communication, and whey miss communication occurs? well i think because sometimes people just don,t have COMMON SENSE….is the lack of common sense the root of all arguments?
nope
because common sense to a farmer is not commom sense to a city slicker
the problem is, everyone should agree with me and they dont
its so sad
peace
