Falcon 9

    Hello there!

    In this post, I want to tell about rocket
  The Falcon 9 but what's so special about it? Well, I won't hold it for a long time - it's a partially -  reusable launch system.

   Okay, so It's just another rocket, which you can use over and over, you can say. And my answer will be "yes", but hold on a sec.

    I think you have already watched this short clip and you know the answer. So fully the answer would sound like: "The Falcon 9 is a family of a Launch Vehicles, the first stage of which is reusable and can land vertically.

  Now I'm going to run through details.

Economic aspect
  Let's begin with numbers. For 2016 year is being announced 16 launches. Each "Falcon" launch cheaper 30% (price drop from 61,2 million to 42,8 million). So, for only one year it's possible to save 480% of the first stage price. This is the most powerful benefit of this program.

Science
 The  main task of "Falcon" is the delivery of goods to the International space station. Which orbit is approximately 25'000 miles above Earth. Landing platform can be located 4 miles to more than 300 miles from the launch place.  One of the biggest challenges was to find the way to keep rocket stable during landing. One of the faced problem's was that engine can't give partial impulse because it's so strong that will push rocked up in seconds. Scientists decided that the best way to solve this problem is to leave the amount of fuel necessary to slow rocket to the zero speed right before it touches the ground. Just imagine how much calculations they made!

Prestige
 Engines for "Falcon" were designed and constructed in the United States . This fact makes the USA more independent from Russian "Soyuz" rockets and also make America lead in space and technology  race with Russia.

 After all, it looks soo cool! And make a the human dream to reach the stars even closer!

Thanks for reading!

For Babies in India, a 30-Foot Plunge for Good Luck

How far would you go to show your religious faith? Many religions have some weird rituals. In India, some families living in a rural area are willing to  throw their babies from the surface  to be caught in a stretched bed sheet about 30 feet below. In addition, who do like this ritual are both Hindus and Muslims. This ritual is long popular in Maharashtra and Karnataka States, they have done almost 700 years, to a time when children's death rate was high, medical knowledge was weak, and families had few places to found help. Legend has it that a saint advised people whose babies were dying to build a shrine and drop the sick children from the surface to a sheet For their children cured of the disease. Villagers believe that the ritual brings the child long life and good luck, and preserve that it does no harm. The ritual continues throughout the year, and they throw  babies even their age  two months.  “We do not support this superstitious practice,” said G. Mohanty, a media adviser at the commission. “It is against the interest of the children. They may be really scared, and nobody knows how it affects their psyche.”. Finally, we did many thing to our children to avoid Illness, but we shouldn’t believe what our parents believe because some rituals are stupid and we said these our tradition.

Which Is Greater, The Number Of Sand Grains On Earth Or Stars In The Sky?

If you lie in a sand desert or on a beach on one of the nights, you can probably count the number of stars in the night sky but if you tried to count the number of sand grains it would perhaps be impossible. It may seem unimaginable even just to think about it. Indeed, scientists could do that. According to Mr.Cain, one cubic centimeter consists around 8,000 grains of sand and there are about 700 trillion cubic meters of sandy area on the ground. Therefore, according to a group of researchers at the University of Hawaii, there are about  7.5x10¹⁸ grains of sand on our planet. However, what is weird is when you know that the numbers of stars in the sky are more than the number of sand grains on the ground. According to Driver, Professor at the International Centre for Radio Astronomy Research in Western Australia and one of the scientists who worked on this research, there are 70 sextillion stars in our planet. Let me show you what 70  looks like: that means there are 70,000,000,000,000,000,000,000 stars! So, we can say that the number of stars is about 10 times more than the number of sand grains of deserts and beaches.

Facebook to Change News Feed to Focus on Friends and Family

8/2/2016  Masataka Kanzaki

 Facebook decided to change the algorithm which chooses contents to show articles posted by someone on your news feed. They also commented for publishers that rebuilt algorithm would reduce the number of advertisements and some links which connect news media site. On the other hand, they put a spot light for the contents which are posted by the friends and family of users.

 This changes will affect all kind of contents posted by publishers, and for some of publishers, especially for small publishers, it’s a serious concern because Facebook has over 1.65 billion users around the world. According to a 2016 study by the PRC, 44% adults living in the U.S. usually read some articles on the WEB. And more than 40% of the readers come from Facebook by tapping news links. It’s obvious that publishers’ sales which are gained by the connection of Facebook might be decreased.

 Melissa Bell, vice president of growth at Vox Media, stands a middle point. “Facebook is a place where people want to share things that matter to them, whether it’s news story or their child walking,” she said. So here is an opposite opinion that the changes will not give publishers huge impacts if most of publishers’ contents come from sharing and commenting of each of users. Nobody knows what would happen in the future.

Harry Potter: Returning to Hogwarts

Last weekend was a magical night for Harry Potter’s fans. The eight-edition of this fascinating story was released at Sunday midnight. According to Melas, in her article published in CNN, many people attended the event wearing wizard hats and caps (2016). Moreover, people did not wait to express their ideas through social media. Melas also claims that some people mentioned on their twitter accounts that they will be back in Hogwarts for the next weeks.

 It is important to make an emphasis that this book has a different author from the first seven-volumes. Harry Potter and the Cursed Child is actually a script from a play, which is being performed in London (Melas; Kakutani). According to Kakutani, J.K. Rowling, the author of the first seven-volumes, narrated the different situations that Harry Potter experienced through his life journey, from being an inexpert child to become a mature young-adult. On the other hand, this new author provides the readers a totally different view of Mr. Potter’s life. He is now an adult, with three children, who works in the Ministry of Magic. In this new edition, it is Harry's and Draco’s children – Albus & Scorpius - who will be directly involved in different adventures along the book.

“The book comes at a time of renewed interest in Harry Potter and his adventures” (Melas). Although Harry Potter and the Cursed Child was written by a different person, the magic of the story is still there. Mr. Potter’s adventures continue and many fans have already introduced themselves in the magical world again.

Harry Potter is still moving crowds and it “could become the top selling book of 2016 for both Amazon and Berners and Nobles” (Melas). Let’s take the Hogwarts’ train again and enjoy the end of this fascinating and magical story.

Liars

How many lies have you said today? It becomes a part of our life, people are lying for many reasons. For example, people may lie when they feel unsafe to protect themselves from a punishment or blame. People may lie to convince others with their opinion and those people are too dangerous because they don't care if they hurt someone, they only care about themselves and the goals that they need to reach. People may lie to make others more self confident or to avoid the embarrassment that they may cause to other if they tell the truth, and this one is usually happen between husbands and the wives or between close friends.

All of us would like to know when people are lying, we all have bad experiences from trusting the wrong person. In the work or in the street we meet strange people daily, even when we speak with our friends. There are many signs to detect a liar. For example, keep an eye on people’s face, liars usually tend to touch their nose more than once or cover their mouth while speaking. Sometimes they suddenly talk faster or slower than the normal. Pay attention to the sentence they are saying, liars usually repeat the same words because they are trying remember certain reason.

Those are a few ways to detect a liar. In addition, there are many other ways to do that. However, those are not a very accurate detectors, many professional liars can deceive you without any sign.
