Ever since computer games have dominated teenagers spare times, not only teenager but also some adults, it is a common sense that the games encompasses violence result in violence. Isn't it? I'm not sure. According to one of the last article of Huffingtonpost, the long-term effect of violent games doesn't end up with violence on users. It would mitigate the all taboos:
The article below has obtained from Huffingtonpost [click]: There has been plenty of research on whether or not violent video games cause aggression in the real world. Famously, we have lawyer Jack Thompson who claimed games like Grand Theft Auto and Mortal Kombat were causing children to attack one another. His claims were met with a moral panic that culminated like all other moral panics― lot’s of hysteria. Thompson’s claims didn’t really get him anywhere but his claim lingered: do violent video games cause violence? Many would be inclined to say yes despite evidence to the contrary. Reality is much more complicated than looking at two things in a vacuum and deciding they are causally related to one another. The video above from Psych2Go looks at the relationship between video game violence and real life aggression. The majority of studies seem to find that aggression and violent video games are linked, but these studies were not conducted under objective conditions and only measured short term effects. However, once studies were conducted that measured the long term effects of violent video games, the results changed. Studies that looked at gamers and aggression levels over longer periods found no difference between those who play video games and those who don’t. So there you have it. There are no long term links between consuming violent video games and real world violence. If you’re worried about exposure to violence only in video games, you’re turning a blind eye to violence elsewhere. Look around, violent video games are nothing compared to the violence we consume in our daily news media.

Lewis Fry Richardson is one of them who had provided thorough contributions to computational methods. I had a goosebumps (you could emphasize my goosebumps if you dare to numerical science) when I learnt that there was human-computers who had been conducting hand-by numerical analysis. Previously, I have advised you to have a look on "Hidden Figures" in which the story relies on some NASA employees carrying out computational analysis by hand-calculations. They all were called "Human Computer" that had even a room which was specified as Computers. The movie based on a true story which emerged in 1961 have unveiled December, 2016. Lewis Fry Richardson and his research group was also conducted hand-by calculations. Figure 1: Lewis Fry Richardson He had tried to solve a numerical problem in accordance with weather forecasting. Despite he had failed several times, he had never given up to dare all those numerical studies. It was curiosity of Mr. Richardson which has dozens of challenge or an obsession. Furthermore, he has a famous quote as below; The dream has come through that he also has conducted the first computational analysis regarding weather forecasting with the first computer ENIAC. Besides, the man also has a summary as a poet which associated with turbulence:
“Big whirls have little whirls that feed on their velocity, and little whirls have lesser whirls and so on to viscosity.” In my opinion, there is a exciting case that the Hollywood should evaluate it. Footnotes: [1] http://www.bbc.com/news/uk-scotland-south-scotland-23242953 [2] https://en.wikipedia.org/wiki/Lewis_Fry_Richardson If you are a deep movie watcher who have a faith in "based on a true story", you would have watched Hidden Figures, at least you have dared. The story is indeed the passion of a group women who had worked NASA to carry out hand-by computational analysis in 1961. The hindrances which they had encountered through this rough path was an exact disgrace. The story went through how did they hurdle things. Of course, I advice. "Hidden Figures is a 2016 American biographical drama film directed by Theodore Melfi and written by Melfi and Allison Schroeder, based on the non-fiction book of the same name by Margot Lee Shetterly about African American female mathematicians who worked at the National Aeronautics and Space Administration (NASA) during the Space Race. The film stars Taraji P. Henson as Katherine Johnson, a mathematician who calculated flight trajectories for Project Mercury and other missions. The film also features Octavia Spencer as Dorothy Vaughan and Janelle Monáe as Mary Jackson, with Kevin Costner, Kirsten Dunst, Jim Parsons, Glen Powell and Mahershala Ali in supporting roles.
Principal photography began in March 2016 in Atlanta and was wrapped up in May 2016. Hidden Figures was released on December 25, 2016, by 20th Century Fox, received positive reviews from critics and has grossed $220 million worldwide. It was chosen by National Board of Review as one of the top ten films of 2016[4] and was nominated for numerous awards, including three Oscars (Best Picture, Best Adapted Screenplay and Best Supporting Actress for Spencer) and two Golden Globes (Best Supporting Actress for Spencer and Best Original Score). It won the Screen Actors Guild Award for Outstanding Performance by a Cast in a Motion Picture."

Rjukan in southern Norway has applied a novel method to obtain sunlight through dark side in a indirect way, reflection. Being located northern hemisphere, some region of Norway has been lack of sunlight through seasons. Moreover, if you dare to locate among mountains and valleys, it is hardly to reach sunlight in a direct way. Even so, they haven’t given up to seek for sunlight. What they did for sunlight? How could we transfer radiation through specific region? Yes, REFLECTION. It seems amazing. Actually, I have been thinking of use sunlight as to indoor lightening method. Having informed about Rjukan, I would start to design mine.
Full story on BBC: The dark town that built a giant mirror to deflect the Sun Smoking...One of the bad habits. I would say that you have to stop smoking If you have, as general. What about the flow after burning ? I have recognize that flow after burning through smoke has no turbulence. Isn't it ? You would support me I guess. Therefore, I, or course, have wondered about it that I have searched on it. There is a transition laminar to turbulence as the photography you have specified. Thanks to Reynolds Number, we could calculated ratio between inertia and viscous forces which is a sign of whether being turbulent or laminar flow. he descent of smoke can be see in the graphic as above. According to lecture note of Victor Zhurbas, the velocity of smoke at initial stage is about 30 cm/s and L is around 3 cm. Kinematic viscosity is taken as 0.14 cm^2/s.
Re= (30*3)/0.14 = 642 Result could be interpreted that Re goes through critical range in accordance with transition definition of laminar to turbulent. The phenomenon is two phase flow that has to be investigated within ambient conditions (velocity, temperature, pressure, etc.), The velocity should increase because the hot smoky region is less dense than the cooler air around it. As a result there's a net upward buoyant force on it, like on a helium balloon, causing an upward acceleration. So it should briefly speed up. Of course the hottest middle part of the plume speeds up the most. Toward the edges, the velocity gets closer to that of the surrounding air. This change of velocity from place to place, called shear, is what can drive turbulence. Whether the flow stays smooth (laminar) or turns turbulent depends on a quantity called the Reynolds number, which involves the shear, the size of the region, and the viscosity of the fluid. Here is a journal article related to mathematical model of cigar smoke. Besides, take a look on “Lewis Fry Richardson” (1881-1953), an English scientist. He interested in atmospheric turbulence and performed many terrestrial experiments. The Richardson number, a dimensionless parameter of the theory of turbulence is named for him. He famously summarized turbulence in rhyming verse in Weather Prediction by Numerical Process (it is also called as a poem as to turbulence): Big whirls have little whirls that feed on their velocity, and little whirls have lesser whirls and so on to viscosity. Have much fun. Yesterday was the Piday. The day which emphasize Pi number. We have every so often encountered it ever since elementary school days. Thanks to Pi, we easily calculate the area and volume of circular elements. For instance, how do you acknowledge that you can specify how to find area of a circle ? The phenomenon comes through division. Check it out as below: It is virtually easy to obtain that you probably could find it yourself but exciting!
Prof. Rhett Allain (associate professor of physics at Southeastern Louisiana University and the author of the Wired magazine science blog) has issued a new article about Pi day. He uses a novel method to acknowledge Pi. If you curious about Python and experimental work, you would fall in love with the issued article. You may bumped into a little bit science. Wisdom is here, have much fun: https://www.wired.com/2017/03/lets-calculate-pi-raspberry-pi-celebrate-pi-day/ Kernel, which has a strong physical bond with corncob, turns to popcorn through heating process. Have you ever wondered as to the reason behind this process that should have been partially easy, right ? Heat transfer coefficient of kernel is quite good. According to BBC future report, 14% of kernel is water. During heating process, 14% of water starts to evaporate through outer skin of kernel. Whereas water vapor leaves kernel, a crack propagation occurs through outer skin of kernel without burn. A boom is realized that results in with popcorn. Click for detailed review of phenomenon. Moreover, popcorn had a porous structure that makes is low-fat snack. It is highly used for diet foods. Here a stunning video that shows you to how porous popcorn. 1 cup popcorn + 1 cup milk = 1 cup popcorn and milk mixture. Monolingual or bilingual ? The cons and pros of language knowledge on your brain has been examined by linguistics. Some of them hardly advocate that being bilingual improves your brain activities. Is it a sight of wisdom or a trouble we have to bother ? Surprisingly, Swedish have been taught Swedish according to Duolingo. Wait a minute. What? Anyway, thanks to the developments, lots of the people start to learn a new language within the novel language app "Duolingo". It is easy to dare and has a user-friendly interface. Humankind really loves being taught within the easiest way. Learning a second language was made easier and more convenient with the introduction of a revolutionary and creative app called Duolingo, almost five years ago. Since then, it has continued to grow its language database as well as its users, going up to 19 languages and over 120 million users! Recently, Duolingo has released the most popular languages that have been tried to learn by millions. Let's check statistics. Fig 1. The most popular language studied on Duolingo in each country. Fig 2. The second most popular language studied on Duolingo in each country. What about Swedish? Duolingo’s Swedish course turns out to be the most popular in Sweden itself: 27% of all users in Sweden are learning Swedish. Why would that be the case? Immigration to Sweden has been skyrocketing in recent years: one in six Swedish residents in 2015 was born outside of Sweden. The fastest growing foreign-born groups are from Syria and Afghanistan, reflecting a recent increase in the refugee population. Duolingo recently released a Swedish course for Arabic speakers, which will hopefully help! But it’s not just Sweden. There are several other countries where immigrants are using Duolingo to learn the language of their new home. In the United States, immigrants constitute 13.1% of the total population. But even more — over 20% of the population — speak a language other than English at home, and over 25 million people speak English less than “Very Well”. Perhaps not surprisingly, then, English is the second most popular language in the United States, attracting 21% of the country’s Duolingo users. The second most popular language in Norway. Another case is Norway, where Norwegian is the second most popular language (with 18% of all users). Similarly to Sweden, Norway has been recently accepting many migrants and refugees. According to the data from the beginning of the year, immigrants constitute 13.4% of the total population in Norway.
