Inspiration.
Gene modification is the key role to alter the behavior of inheritance. We are responsible/the result at least half of it from the inheritance and half of it from patterns recognition...

Engineering Airbus A380/Boeing747, diamond and satelite
Airbus a380 costs 375 millions, can carry 500-800 passengers and weight over 300 tons
Do you know that the 2 pilots can not order the same meal during flying they're afraid of food poison, it is interesting that people thinks the ways to minimize the risk.
I flied Boeing 777/747 many times but not with A380 and 787.
You need to go to the university in order to become a design engineer.

Fibonacci sequence/numbers
As I said before art is a source of knowledge and geometry. Art is a science. The flowers pedals are created by Fibonacci sequence. I recently was asked to write C/C++ for Fibonacci sequences in 1 line of code. Toi co lan da noi nghe thuat la tong hop cua kien thuc va hinh hoc/dai so. Gan day toi co viet phan mem ve Fibonacci circular arcs, nhg canh hoa/van vat dc tao hoa tao ra phan lon theo Fibonacci sequences or numbers. Education has to be fun and interest like playing a video game and we should tell the reason why? As you see the video you can tell how important is Fibonacci sequence effects in the creation of things around us.

In mathematics, the Fibonacci numbers or Fibonacci series or Fibonacci sequence are the numbers in the following integer sequence:[1][2]
By definition, the first two numbers in the Fibonacci sequence are 0 and 1, and each subsequent number is the sum of the previous two.

#include <iostream> using namespace std; //write the fibonacci sequences in 1 line of code. unsigned int fibonacci(unsigned int n) { return n < 2 ? n : fibonacci(n-1) + fibonacci(n-2); } int main() { unsigned l; cout << "type a number:"; cin >> l; cout << "number " << l << " fibo is " << fibonacci(l) << endl; return 0; }“Philosophy (nature) is written in that great book which ever lies before our eyes. I mean the universe, but we cannot understand it if we do not first learn the language and grasp the symbols in which it is written. The book is written in the mathematical language, and the symbols are triangles, circles and other geometrical figures, without whose help it is humanly impossible to comprehend a single word of it, and without which one wanders in vain through a dark labyrinth.” - Galileo Galilei

Leonard de Vinci
Leonard de Vinci - a famous painter and a great military engineer and an architect, he designed a tank 400 years before the World war 2 started. Art and science is very closed depending how you look at it. Painting is a source of knowledge and geometry.

Bullet train 575 km/h & Air Force One.
Saigon to Nha Trang is less than an hour. It is now in France/Japan.
And Air Force One. On Sep 11 we took the president on board Air Force One and the destination was unknown. This type of Boeing 747 or the new one 777/787 and Airbus 350/380 can fly 1000 km/h with the range 10k-15k without refueling.

“hyperloop” high speed transportation
Travel from New York to China in 2 hours. NY to LA in 45 minutes. The hyper loop.
It took me more 9 hours to drive from Ha Tien to Saigon by Honda scooter (5am to 2:30pm) or from Saigon to NhaTrang. It took me 8 hours to fly from Saigon to Melbourne-Australia and more 20 hours to fly from US/Canada to VN either through Atlantic or Pacify ocean. From NY to Paris is 8 hours and Paris to VN is 11 hours or from NY to Hongkong is 16 hours and HongKong to VN is 2.5 hours.
Before I thought it will be faster to fly over Pacific ocean because it seems shorter but the last 2, 3 years I flied over Atlantic ocean to VN via Paris/London/Germany, it takes almost the same time maybe 1 hour more but this route is fewer people traveling so it is less crowded than HongKong/Bangkok/Singapore.
With the hyper loop will take me 2 hours to VN and I hope that I am still alive to ride on it. When I was young that I had a crazy idea that flying into the low orbit and waiting for the earth moves to a certain point then reenter to the earth, it seems crazy but now you can do it with 200 k via Virgin Galactic.
I recently did a research on magnetic field, it is incredible that how much it can do because I just want to invent something relating to renew energy using magnetic field, it called permanent magnetic alternator, its energy will last up to 400 years.
Play guitar, graphic/software design, cook, tennis, swimming...now one more hobby for me try to learn/design a green energy but I have so little time to do anything. I know how to write real time software and graphics recently learning more object oriented programming languages and set out to do all by myself. A lot of ideas but so little time to try. (Song can co mot ly tuong va huong di ro rang chinh vi vay cuoc song moi thu vi hon, an uong ngu la chuyen binh thuong minh can cai gi do hon vay)
It seems an engineer you can do a lot of things, you can fly an airplane like a pilot if you want to because it is easy or become a doctor it is easy too than write the software and learn the new technology at the same time everyday it is very hard and earn the living that way, to me it is awesome and challenge but it requires a lot of work. Everyday is a new thing and looking forward a next day. That maybe a happiness? because you love what you're doing but it will not be the same if you marry.
More things to learn because everything is on the internet like an open book and it is ready for you to read. A couple of weeks ago I was reading how to go to Mars and it was not difficult to understand if you have a background and everything that I read it makes sense. NASA will contract to private companies for space explorer as the US Defense department did to the internet by giving the protocols to private companies to continue to develop and look what it turns out today. The private companies here tend to do a better job than the government because the competition in the twenty-first century capitalism. I think the technology for space explorer will be develop very fast in the next few years together with biotechnology.
Before I thought it would be so difficult to go to Mars but it is not because there is no friction/gravity and ....
Maybe one day ....and the hyperloop will be like the internet now and there will be no boundaries. The hyper loop concept is the same as travel into space when there is no air and no friction/gravity at all, the speed can accelerate greater 4000 miles per hour so from LA to Beijing is 2 to 3 hours that it is about right. It is not science fiction but it will happen based on physics laws and principles.
So the point that I like to make here is thinking is one thing but doing it is a another thing sometimes you have to change the design many times because you are the first one to do. The result is uniquely if you can effort the time to do it. At work we don't have the time so we patch very quick and start do an other thing because the companies like to push you to get the best out of you.
....But to know but not yet to do is not yet to know.
The computer can sketch me in a few seconds even print out with 3-D image. I believe that if we apply the principle into the laws of physics it will serve us well. In computer and science everything has the reason of it, even a blank page loads into the webpage it may not working, not because of the blank page but the object is placed before it (encapsulation). The object is derived from a parent class and it has characteristics or attributes - same thing as us. Everything is object including people we are an object to move and interact to each other. Many programming languages are based on object oriented from creating an object until destroying an object to free the resources for a computer to run forever. It is similar to human being. Most of computer ideas are adopting from our daily life activity for example IP address - Internet Protocol address is the same label of your home address where you live in must simple way 192.168.0.1 of 32-bit or 64-bit address. Object is created to serve our purpose and it must be freed. Object and its attributes/signatures are a complex affair.

To Mars ≈ 225 million km
Hope is Contagious - Barack Obama.
Study physics, and learn how to reason from principles versus analogy - Elon Musk.
It's take 10 minutes to orbit. With zero gravity no need for the rocket engine, all it needs a trajectory toward Mars and because no friction it will accelerate by itself or with small boosters when needed (the path of a projectile or/of objects moving through space). The equipments are powered by the solar panels. To return just do the reversed trajectory. It takes 6 months to Mars. Mars is only slightly longer than an Earth day: 24 hours, 39 minutes.
≈10 minutes to orbit with speed of March 25 and March 3 is just enough into space. Low earth orbit is 220 miles km of the sea level.
The colonization of Mars. - Rocket Science.
“That’s one small step for a man, one giant leap for mankind,”
Astronaut Neil Armstrong of Apollo 11
"Imagination is more important than knowledge."
"The whole of science is nothing more than a refinement of everyday thinking."
"Science is a wonderful thing if one does not have to earn one's living at it."
“If at first the idea is not absurd, then there is no hope for it.” Albert Einstein

Innovation
In order to do it you need to know this is why we spend a lot of time to study. With knowledge we can do...an extraordinary things. Life will be interesting to live because your passion is eager for doing a new thing. The things that you love to do. It is not about money. It is beyond money because everyone can earn money, this is about an exciting and challenging when coming to work.
SpaceX vs. Virgin Galactic in space explorer. Imagine that you could do this kind of work, it is so cool.
Don't limit your ambition, go back to first principle be ready to make mistakes toward your goals until then you have served someone 's ambition. You have to know yourself to be able to use yourself as a full potential for humanity.
