Introduction

Artificial Intelligence is surpassing the human mind, developers are upgrading it to make it beat even strategy games world champions. And that’s what happened to the champions of Chess and Go.

Garry Kasparov

Kasparov is a Chess prodigy from Azerbaijan and was skillful since childhood. At 21 he played Anatoly Karpov for the world title but the 49-game match ended indecisively. The next year, Kasparov beat Karpov to be the youngest champion in Chess history. With a streak of 12 world titles, Kasparov was considered as the greatest chess player in history, or rather the greatest Human chess player in history.

Chess-playing computers

They had existed since the ’50s, but they initially saw little success against accomplished human players. That changed in 1989 when IBM charged a team led by Chinese C.J. Tan with creating a computer capable of competing against the best chess players in the world. The resulting supercomputer, dubbed Deep Blue, could calculate many as 100 billion to 200 billion moves in the three minutes traditionally allotted to a player per move in standard chess.

Kasparov vs Deep Blue

Kasparov first played Deep Blue in 1996. The grandmaster was known for his unpredictable play, and he was able to defeat the computer by switching strategies mid-game. In 1997, Kasparov abandoned his swashbuckling style, taking more of a wait-and-see approach; this played in the computer’s favor and is commonly pointed to as the reason for his defeat. Kasparov’s last game against Deep Blue in 1997 lasted only one hour. Deep Blue traded its bishop and rook for Kasparov’s queen, after sacrificing a knight to gain position on the board. The position left Kasparov defensive, but not helpless, and though he still had a playable position, Kasparov resigned, the first time in his career that he had conceded defeat. Grandmaster John Fedorowicz later gave voice to the chess community’s shock at Kasparov’s loss: “Everybody was surprised that he resigned because it didn’t seem lost. We’ve all played this position before. It’s a known position.” Kasparov said of his decision, “I lost my fighting spirit.”

Extra: Google AI defeats human Go champion

Go is a Chinese strategy game where players take turns placing stones on a 19-by-19 grid, competing to take control of the most territory. It is considered to be one of the world’s most complex games and is much more challenging for computers than chess. Google’s DeepMind developed an artificial intelligence called AlphaGo that defeated the world’s number one Go player Ke Jie. DeepMind founder Demis Hassabis said Ke Jie had played « perfectly » and « pushed AlphaGo right to the limit ». Following the defeat, Ke Jie told reporters: « I’m a little bit sad, it’s a bit of a regret because I think I played pretty well. » AlphaGo has built up its expertise by studying older matches and playing thousands of games against itself.

Conclusion

The companies say that the eventual plan is to deploy its artificial intelligence « in areas of medicine and science ». Prof Noel Sharkey, a computer scientist at Sheffield University, said it is still a long way from creating a general intelligence. The types of intelligence exhibited by machines that are good at playing games are seen as very narrow. While they may produce algorithms that are useful in other fields, few think they are close to the all-purpose problem-solving abilities of humans that can come up with good solutions to almost any problem they encounter.

Chapter 2 : England, the Discovery of Vaccines.

Fast breathing, clenched fists, and hunched shoulders are common signs of tension that most people show as the vaccination syringe approaches the body whilst 300 years ago people took the same syringe with great joy and hope.
The reason is that we are clueless of what humanity endured before the « blessing » of vaccines came to light.
Let me tell you the tale of one of humankind’s greatest inventions through the eyes of a time walker. This invention actually underwent a lengthy process of discovery, development, and improvement that lasted for centuries.

And our wanderer walked down the lane of the 1700s, when English physician Edward Jenner overheard a girl boasting to her friend that she would not contract smallpox because she had already contracted cowpox and she will have a flawless face free from pox blisters.

The doctor thought that the idea was brilliant even though it seemed silly.
Why not provide cowpox vaccination instead of the usual inoculation which involved inserting fresh smallpox material, such as blisters from a sick individual, under the skin of a nonimmune person considering that 3 percent of people died due to variolation using the previous method?
Smallpox and cowpox both belong to the same family « poxviridae » and once the disease is transferred from cows to people, it became weakened
In order to give the immune system the memory it needs to fight smallpox once it enters the body, the doctor came up with the brilliant idea of infecting his patients with cowpox, which is contagious but much less dangerous than what smallpox can do to a human. He called this procedure « the variolae vaccine » and performed it on a boy for the first time. In 1796, at that same time, the idea of a modern vaccination was born. The boy lived and showed no signs of smallpox. And Edward Jenner branded himself as « the father of immunology » in history.
From that time until 1850, vaccination evolved, and then the arm-to-arm vaccination practice emerged, posing a safety concern because this new method of immunization allows for the transmission of bacteria and other diseases from one person to another.
Sydney Cooper, a microbiologist, discovered in 1896 that adding glycerin to the blistering agent used during the procedure could make this vaccination safer.
As a result, scientists were able to create the vaccine « dryvax, » which was used in the 1967 big WHO vaccination campaign that was a complete success.
The smallpox was eradicated, and research continued in the years that followed to reduce the vaccine’s side effects and make it more effective.
With knowledge, observation, try and error as well as the absurd notion of a normal girl, which we can term « luck » and the culminated work of many minds, many hands, many hearts during hundreds of years, this holly tool of science was created.
People like us who were born in an era where a new vaccine could be developed in one or one and a half year to stop a worldwide pandemic are unable to appreciate the blessing that this discovery brought to the world.

One of the deadliest diseases in human history, smallpox is believed to have killed hundreds of millions of people throughout history with a death rate of 30%, compared to coronavirus’s 3%, just to imagine the nightmare it caused to humanity; the battle that humans won against it is one of history’s greatest victories.
Granted with hardiness and protection, waiting for the secret work of a needle in their bodies, with calm breaths and relaxed shoulders people received their vaccine.
May humanity always strive in preserving a world rich of life and vitality.
