If Leonardo da Vinci was alive


Leonardo da Vinci is the man everybody admits is a genius. He invented, drew, and created lots of amazing things. There have been so many geniuses in the world and above all, I think he is a unique type of genius because he was active in lots of different fields; invention, painting, sculpting, architecture, science, mathematics and so on.

We know many geniuses but most of them displayed their talents in specific fields, Vincent Willem van Gogh was a remarkable painter, but he was not a genius of science, Albert Einstein was a genius of theoretical physics and he could play a violin well, but he wasn't a genius of music. Therefore, I think Leonardo da Vinci was a rare type of genius, and the word universal genius is for him.

Admitting his greatness, whereas I also take a different view of him.
In the modern world, everything is becoming subdivided. I haven't made sure of it, but I think that the times when Leonardo da Vinci was alive, things were not so complicated like now.

I wondered what he would be doing if he was alive now?
I think he is a man who is full of intellectual curiosity, so maybe he goes to university to study several different curriculums. In my extravagant imagination, he lives somewhere in San Francisco and works for an IT company, like Google and draws pictures on his off-days. It's fun just to imagine, isn't it? What I mean is, if he was alive now, I don't think he would be able to be a universal genius.

I have heard a former electrician say that he could repair most electric appliances by himself long ago, but he cannot do it now. It's not just because he has got old, every product has evolved. When he was young, he knew how an electric fan works. However, nowadays, televisions, alarm clocks, toasters, ovens, almost every product has microprocessors and it's beyond the range that he can understand.

Things are subdivided, and there are experts in every field.
It's a clear fact that Leonardo da Vinci is a genius, but if he lived in the current world, I think he wouldn't be able to be that famous, Leonardo da Vinci who lived in the Renaissance period.

There is a huge amount of talented people in the world and I believe there are some of them who have a talent like Leonardo da Vinci. Actually, there are people who are making remarkable activity in plural fields. I mean it's not many different categories, as Leonardo da Vinci got involved, just two or three. (The world is huge, it might be only I who doesn't know their presence.)

This is a bit of an old example, but John von Neumann was a multi-task genius. He showed talents in mathematics, physics, mathematical economics, and meteorology. These people are similar to Leonardo da Vinci.

The difference is these people don't display their talents in many different fields, but if they had lived in the Renaissance period, I wonder what they would have done? Thinking of the current world that has subdivided fields, it's remarkable to have talents even if it is in two or three categories.

You may encounter a modern version Leonardo da Vinci some day or it might be you?

The blog nobody visits


Since I have started this blog in late February, a month has passed.
I haven't told my friends about my new blog, so this blog hasn't been linked from any websites and blogs. Only Google knows it.

Usually, people try to promote their blogs to others. It's disappointing to know that no one knows and reads your blog, isn't it? I want someone to read my blog too, but currently, I'm not going to advertise my blog, I will just leave it and will see how it goes.

I saw the Google analytics page yesterday, and the result was there's no one who visited my blog. I wonder who and when the first visitor will come?

You may think what is the purpose of keeping such a blog that nobody reads. There are two reasons; one is for writing what I'm really interested in, and the second reason is for improving my English.

So far, I'm satisfied keeping this blog. I'm not disappointed having a blog that nobody has visited yet. I don't expect the blog can be widely known easily. If I have kept the blog for about three months and am still not able to have any visitors, then I'll be disappointed.

Let me leave it without links at least for a few months and see what will happen.

Do scientists invite total strangers to their home?



Long ago, I read one of the books of Carl Sagan. I remember that I was reading it intently, and after that, I saw a movie that was made based on Carl Sagan's book "Contact" on TV. In that movie, my favorite actress Jodie Foster plays the main character and I recorded it and saw it again and again. Since then, I came to like seeing science fiction movies often. My favorite movies are "Interstellar", "2001: A Space Odyssey", "Contact", "The Martian", "Moon", "Inception" and so on. These movies gave me lots of simulations of science and I started to pay attention to the real world's science more than before.


I heard the Voyager was loaded with the Golden Record and was launched in 1977. The Golden Record contains greetings in 55 languages, music and more than 100 images.

Firstly, I thought that was amazing. It made me feel that the world I had seen in the science fiction movies had arrived. I simply thought it was a good idea to send messages into space, but gradually my opinion has changed. The reason I have changed my idea was I have seen one image, a solar location map. The question I have got in my mind was very simple.

Do you tell a stranger your home address?

In the movie "Contact", an extraterrestrial who has a gentle mind and who is thoughtful of human beings appeared. On the other hand, in "Star Wars" there is a war the same as the title and a massacre is taking place. The extraterrestrials in these two movies are different types and I think, in the real world, these two types of extraterrestrials can exist.
Yes, I believe that there is intelligent life in the universe somewhere.

I have seen pictures of so-called UFOs, but that isn't the reason I believe in the existence of intelligent life. The universe is huge, far beyond our imaginations and I think the possibility of existing intelligent life is high, but they are not close, I don't think they are our neighbors, somewhere far far away.

History proves that human nature may not be better even if we become intellectual. In the old days, there were uneducated people who had a warm heart and were kind everywhere in the world. On the other hand, there are more educated people in our society now, but there are still people who are brutal and selfish. As you can see in the news, there are still wars and massacres occurring in the world. I think creatures like extraterrestrials might be the same as us. I hope that they have sense and a thoughtful heart, plus the same feelings of value and morality. This is very important. I don't think that it will come true, but for example, if extraterrestrials came to the earth and found that there are many natural resource that they wanted to get on the earth, they can get it by force. To speak of extremes, if they thought that human beings seemed delicious to eat, what could we do? The only thing we can say is we don't know what extraterrestrials think of.

Sending messages to unknown creatures that might have been higher civilizations and dropping a bottle into the ocean containing a letter, can expect very different results. Sending messages and the location map into somewhere in the universe seems to be risky. We don't know what kind of creatures they are. If my memory is correct, the Canadian Museum of Nature in Ottawa once displayed a doll of the creature "Dinosauroid" that the reptiles evolved. They might be like that doll. The doll didn't look well-disposed.

In the time period that current people are alive, I don't think it will happen, but if extraterrestrials visit the earth in the future, there are lots of things that we have to consider. How about quarantine? They might have an extraterrestrial virus. This reminds me that many Aboriginal people died because the Europeans brought viruses long ago. The same things might happen too. Am I too pessimistic?

If it's possible I would like to take Voyager's solar location map back. Where is it now? Oh, no, it may be outside of the solar system already! The feeling I have got now is similar to when I sent an email to the wrong person. It's too late!

I know that the scientists who prepared the Voyager Golden Record had certain reasons and they thought it's good for humanity's future. I think they are very smart people, and I know I'm just a pessimistic ordinary person who doesn't have any special knowledge of space science but let me ask them a question.

Do you send an invitation card to total strangers to your home party?
