A robot to teach children programing

 Robot toy maker Sphero has announced a robot car toy designed to teach young children the basics of programming.


It's called Sphero indi, and kids can program it using simple colored squares that fall on the ground, or a mobile app as kids develop their programming skills.


And Sphero indi uses a color sensor on the underside of the pickup to check which square it is driving over, with a green square telling it to speed up, a pink square telling it to turn left, a purple square telling it to stop and celebrating, etc.



To teach children how to create instructions to get the robot to move from one place to another, the game comes with cards that include patterns with missing square pieces, so the child has to know the colored square that helps the car reach its target.


And the Sphero indi robot can follow the instructions of the tiles without any kind of phone or computer connection.


And if kids are ready for more control, the Sphero Edu Jr app allows them to use a block-based language to customize vehicle behavior via simple drag-and-drop programming blocks that can be linked together to create more complex movements and behaviors.



It also increases the challenge for children with puzzles that get more difficult to solve as the child progresses, and he begins to master the concepts of software and robots that are presented.


The game helps enhance children's problem-solving skills, teaches patterns and concepts such as cause and effect, and reinforces basic kindergarten curricula, such as color.


MIT's Scratch programming language provides students with a playground to discover how computers use logic, with many exercises that involve solving puzzles and mazes using code.



The robot will not be available until September, but it can be pre-ordered in one of two groups:


$ 125 Educational Robot Student Kit, Includes 1 Robot, 20 Colorful Silicone Squares, 15 Programming Challenge Cards, and Protective Case.

The $ 1,200 Educational Robot Class Pack, designed for schools, includes eight of everything (160 silicone squares) plus a larger bag that can ship all the robots together.

It is noteworthy that robotic toys for educational purposes are nothing new, as the Cozmo robot, previously made by Anki, used the Scratch-based programming language to get children to control the little robot

the american how give the soviets the nuclair bumb

 After World War II; America was the only one with the secret to building a nuclear bomb, which gave it a source of power and hegemony over the world.

Theodore Hall is an American spy who pulled the rug under the feet of his country, and leaked this secret to the Soviets, but the strange thing was that he escaped from punishment, what is the story, how is that? This is what we will know in this post.

Theodore Hall was born in New York City in 1925 at the time of the Great Depression from Jewish parents, the economic crisis greatly affected his family and his father lost his job, which forced them to move to Washington, but all these difficult living conditions did not hinder him from learning or rather mastery.

Hall showed extraordinary ingenuity in mathematics and science, which made him join Townsend Harris High School for Gifted Boys at an early age, to end up with a graduate at Harvard University in 1944 at the age of eighteen.

A year later, at the recommendation of American physicist John Van Fleck, Hall was among the youngest scientists recruited to work on the secret Manhattan Project to research a nuclear bomb, where he actively participated in the manufacture of the atomic bomb called "Fat Man."

According to what he said later, Hall was at that time concerned about the danger of his country alone possessing the atomic bomb, which, according to his opinion, threatens the transformation of America into a fascist force threatening world security and peace.

Theodore Hall was influenced by Marxist thought based on his fellow dorm room mate Savile Sachs, who was born and raised in New York City but to Russian immigrant parents, Sachs was a fanatical communist, and he was the one who recruited Theodore Hall to work for the Soviets as a spy to transmit nuclear information.

In December of the year 1944 Hall and his friend Sacks leaked the first American nuclear secrets, the leaks were information containing everything you need about the manufacture of the plutonian bomb, and they remained with them for a long period of correspondence and detailed leaks.

Less than five years later, on August 29, 1949, the Soviet Union announced the manufacture of its first plutonium nuclear bomb, known as RDS-1, which was very similar to the American bomb known as "Fat Man".

The announcement came as a piece of snow and a strong surprise to the Americans, because this great similarity between the Russian bomb and the American "Fat Matt" bomb led them to suspect the leakage of their confidential information. Therefore, investigation and investigation efforts intensified.


In 1950, while Hall was working on his PhD at the University of Chicago, elements of the FBI raided his home. He was investigated and faced with charges of espionage in favor of Moscow, but he did not confess and denied all charges.

The Americans had leaked Russian cables confirming Hall's involvement in transmitting classified US data related to the manufacture of the atomic bomb, but the disclosure of that evidence would reveal to the Soviets the ability of Washington to decode its secret messages, and thus it would change its approach, which would greatly harm US intelligence plans.

The Americans preferred not to disclose their evidence, so when Hall was brought to court, the jury only found him acquitted of the charges against him, due to the lack of evidence of his involvement, and as a result of these considerations, Hall escaped with punishment.

In fact, the telegrams did not even confront him at the time, so as not to convey the news to the Russians!

After his release, Hall remained concerned about his arrest and indictment again, which prompted him to give up residency in America and move to the United Kingdom, after receiving an offer from the University of Cambridge to work there.

Hall was referred to retirement in 1984 after a life full of paradoxes, where he had quiet years, before his past attacked him again in 1996, when his story was revealed by lifting the secrecy of his telegrams with the Russians, and it became available to all.

At the time, Theodore Hall told the New York Times: "They claimed, I changed the course of history. Perhaps if it hadn't changed, the world would have witnessed a nuclear war in the past 50 years - and the bomb might have been dropped on China, for example in 1949 - well, if I had prevented it from happening." So, I accept the charge. "

The example that Hall intended in 1949 was when Mao Zedong declared the People's Republic of China on 10/1/1949 and brought down the pro-American Kuomintang government.

Were it not that the Russians had nuclear as a deterrent, America would have used nuclear weapons again

Howe lived for the rest of his life in Britain and died after suffering kidney cancer in 1999 at the age of 74

The invention that will change the world

 What is the last thing they reached in the world of technology?

Reading time 00:45 «

There are many things that technological advancements have achieved in recent years in all fields, and perhaps the most prominent is the "Neuralink" segment that will change the future in a frightening way.

The chip will be installed in the brain .. The chip reads everything inside your brain’s dialect, and it will perform almost all the functions .. You will expect, plan and solve all your problems, and the place of implantation will allow it to treat many problems such as vision, hearing, memory, psychological problems and addiction ... etc. 😮

You can also communicate with the chip through your electronic devices such as the phone, and the car, and it will have a permanent development of the chip, for example there will be an upcoming development, through which you will be able to cancel any feeling that hurts you, such as feeling pain and sadness 🙄

You can also control your memories and even your dreams and store them in the form of files .. If you feel upset, you will be able to activate the memory that will make you happy.

This achievement is still under experience, but it is considered one of the most important that the human mind has reached ... 🤷‍♂️

What did you think was it possible to apply this slide in the real world? Give me your opinion in the comments ... 🏃‍♂️

How to make a screen capture with android??



It depends on the version of android that you:
- For android 4.0, 4.1, 4.2, press the button "on / off" and "Down" at the same time, until the image is saved to your gallery
- For android 2.2 (froyo), press the "back" button and "on / off" at the same time
- For android 2.3 (gingerbread), press the "home" button and "on / off" at the same time
- For android 3 (honeycomb), it is your rooter machine, which depends on the exact model. Search "root model" in google.

In all cases, you can also install an application (free) to make copies as Wallpaper "No Root Screenshot It" or "Screenshot UX". In some cases (it depends of the model), it may be you need to initialize your android with an application that runs on your PC / MAC (this is explained in the manual of the android applications).
