When it comes to search engines, I believe that all the web surfers will not be unfamiliar. After all, even if the guys now search for something less, take Baidu, Google and so on to test the network is not broken, but also quite practical. But recently discovered a different from the traditional search engine, it’s damn unique charm, it attracted me deeply. And it is WolframAlpha.
The most intuitive difference between it and other search engines is that this guy does not search out a web page.
Instead, it’s like an accurate and fast encyclopedia that gives you direct answers.
For example, type “donald Trump‘s height – obama’s height” in the search box of the website.
The results of the search will not appear what height increase surgery ads, or other have not.
Instead, they tell you that Trump is 6 centimeters taller than Obama, without saying a word of nonsense.
Similarly, a search for France vs Germany will bring up comparisons of economy, Culture, Education, and so on.
We could go even further and ask, for example, “How many marbles can fit inside a Boeing 747?
And the results are just as plain and boring, giving the process of calculation and telling you the numbers directly.
Of course, these numbers are not just given out by WolframAlpha to fool honest people. The sources include major academic websites, Dow Jones, the U.S. Address Bureau, and so on and so forth.
If you were to look for these data individually, it would take a lot of Time.
But the amazing thing is that the above is only a small skill.
Because this site to do a variety of science and technology topics, more brutal to the extreme. The foreign media Wired has reported: WolframAlpha makes it extremely easy for students to cheat.
And there are colleagues in the editorial department said that their own university’s high math, in fact, is this WolframAlpha taught.
Other than that, let’s start with an indefinite integral to practice. I found an indefinite integral problem on the Internet that required the commutative method.
The answer was given directly, and the details were in place, and the final constant C was not missed.
After clicking on the Step-by-step solution, the detailed solution steps will pop up.
We can also see that WolframAlpha is indeed showing the permutation method.
The numerical reasoning questions on the civil service exam are just as easy for WolframAlpha.
For example, this question would be impossible to solve even if you were bald.
But just type the corresponding number into the search box, and it will immediately find the pattern, and than the next eight or nine digits are calculated for you.
In addition, WolfamAlpha can also generate images based on the corresponding function expressions, so there are people who have this thing to play a fancy.
For example, it has been used to convey some sour messages.
After typing the expression word for word into WolframAlpha, the mystery of the image is finally revealed, and a heart appears at the end.
So, his goddess is being sarcastic about his lack of heart and lungs, fellow poor people, do you think I understand correctly?
Similarly, when I tried to enter the legendary heart line expression r = a( 1-sinθ ) given by Descartes to the Swedish princess in the search box, the result was not disappointing either.
I never thought that mathematics could be so romantic.
Also because of the whole work of the guys, WolframAlpha also appeared on some very special images.
For example, if you type trump curves in the search box, a sketch of Trump will appear on the Cartesian coordinate system.
What’s more interesting is that WolframAlpha also gives a specific expression for this image.
In addition, like what Obama curve, Einstein curve have everything, this may be the so-called hardcore play it.
However, you may not believe it, these features above are actually only the tip of WolframAlpha.
According to the description on their website, WolframAlpha can also complete queries, calculations and analyses in statistics, computer science, physics, chemistry, materials science, engineering and so on.
In short: what you can do with it, depending on what you know.
So the question is, how exactly does WolframAlpha do all this?
Well, it’s all because of the hot man behind it named Stephen Wolfram.
Obviously, you can see from the haircut that the big man has a lot of power. And after you know the great achievements, I believe that you will also respect him as Dana.
To put it simply, he was already publishing physics papers in journals at the age of 15.
When he entered Oxford University at the age of 19, he got bored with the course and dropped out to study at Caltech, where he received his PhD in particle physics at the age of 20.
Two years later, he received the MacArthur Genius Award, the highest cross-disciplinary award in the United States.
This award is known as the “local version of the Nobel Prize” in the United States, and is usually given only to the leaders of the profession, including the father of the World Wide Web, Berners-Lee, the genius of Chinese mathematician Tao Zhexuan and other big brothers have won this award.
However, this is not the end.
In the year or so that followed, he created Mathematica, a software program.
Before that, calculating numerical values, solving equations, and drawing graphs had to be done on each Family‘s own software.
Mathematica came along and unified all of this. Its full-featured and powerful functionality helped many scientists and mathematicians simplify their calculations.
Today, Maple, Mathematica, and MATLAB are known as the top three mathematical software programs in the world, and the release of Mathematica is considered to be the beginning of modern scientific and technical computing.
On this experience, I believe that even the film would not dare to do so.
Interestingly, Mathematica is not Stephen’s proudest work, but his 2002 book, A New Kind of Science, is his favorite.
His book, A New Science, was his favorite, but it was not well understood or applauded because it was a study of cellular automata.
But Stephen still thinks that this book tried to introduce computation into science, so he is as disruptive as Newton’s work to the scientific community.
Another little story is that Stephen was going to ask Steve Jobs to write a recommendation for the book, but Jobs refused because Jobs said, “Nobody wrote a recommendation for Newton’s work, so why do you need one?
Of course, Stephen and Jobs were actually very good friends, and Mathematica was Jobs’ name.
The business card that Jobs handed Stephen when we first met is still in his possession.
The WolframAlpha website, which he introduced at the beginning, was launched in 2009.
Stephen thought that search engines, including Google, were only retrieving data, but not trying to understand, analyze, and compute it, and that people needed something that could be used to solve unknown problems.
This is the main reason why he launched WolframAlpha.
So, when people type 200g milk + 500g rice into the Google search box, they get Food ads.
On WolframAlpha, it’s the nutrition table for the corresponding food.
WolframAlpha is more of an encyclopedia than a traditional search engine, an artificial intelligence that combines computation and knowledge.
WolframAlpha has also been labeled as the “Google killer” by the foreign media.
Stephen’s ultimate goal is to make the machine truly understand human speech. He believes that artificial intelligence is the door to the future.
And he also hopes that he can be the one to open that door.
Meanwhile, in April of last year, Stephen posted on his website, “We may have found a path to the fundamental theory of physics, and it’s beautiful.”
Let’s just say that all this is no longer within the realm of comprehension.
Finally, I was curious enough to do a search on WolframAlpha for “The Ultimate Answer to Life, the Universe, and Everything.” (Answer to life, the universe, and everything).
WolframAlpha, like The Hitchhiker’s Guide to the Galaxy, tells us that the answer to all of this is “42”.
