- Japan's famous bullet train used to make a loud boom when it travelled through tunnels. But, thanks to a spot of bird-watching, an engineer was able to fix the problem after he was inspired by a kingfisher.

there's one more thing, the shape of entrance and exit of the tunnel is an oval shape whose top is inclined towards left when seen from front view, this does the remaning job , just the triangular feature of engine is not enough to reduce the sound wave.
A century ago a Japanese science teacher said to the students, "The best teacher is nature."
The stone monument in which curved this saying is built in the university in Yokohama, JAPAN.
That’s biomimicry. Sometimes the best solutions can be found in nature.
And all because of Eiji Nakatsu, who was a birdwatcher 🦅🦆🦉🦜🦚
Thank you for providing this information. I found an interesting article about Eiji Nakatsu and Biomimicry!
awesome animation from bbc
See, the God is the best designer !
Alhamdulillah!
If by God you mean Jesus
Ebony Maw god is one ☝️.he is god of me,you,Jesus, Moses ,Muhammad (peace be upon them all).

semma kandu pudippu ya
Waouh ! It is very interesting!
Wow, so they literally needed a bird to figure out that it needed to be more aerodynamic. Good one BBC
Cool
Damn !
Anthony Warner's book brought me here.
Kingfisher :- the king of good times😀😂😁
Mother nature rules
Yet, many believe the Train was created but the technology in the Bird was an accident!!
Glory be to God. Alhamdulillah.
@Data Crunching So you believe mindless atoms and molecules created life and gave rise to consciousness and produced complex and highly intricate entities like coded immaterial information? Lifeless and unconscious atoms gave rise to complex languages like Chinese, english and HTML that are present in your DNA? That really makes sense! Where did the atoms and molecules came from? Nothingness? But from nothing only nothing comes! Did the universe created itself like a mother giving birth to her own self?
Peace be upon you.
@@AnkitKumar-bg2gm :) you too have faith in the scientists.
@Data Crunching :) Good question. But you would only ask that because of your preconceived notion that the Universe had an eternal past and that is a logical impossibility. Remember what happened when Einstein added the cosmological constant into his theory of relativity? Because he and many others like your self believed in the steady state theory too. It was as he declared, his 'greatest blunder'.
I believe there must be a Creator Who created all that once begun to exist. Universe begun to exist. Time-space begun to exist. Where did it come from? Nothingness? But if the universe had an Eternal past or you would not have the world that you have today, hence, something had had to get things stated. If God too had a cause than you are actutally subscribing to the steady state theory. The God is the Creator not the creation and without the creator you would wouldn't exist or time and space etc.
Peace be upon you.
@@abuamanah9176 yes. How do you "explain" the existence of your god, other than in your mind?
@@richardelliott6210 :) Exactly the same way you would prove the existence of your mind. Does your mind exist? I haven't seen it, have you?
The country name word "NIPPON”(Japan) means "the land under the sun" , but another name is "WA" or "YAMATO" , meaning “Peacefully Harmony among People and with Nature”. So Japan's name means “the Land under the Sun” and” the Land of "Great Harmony of People and Nature,”
The history of Japan is very old, about 2,000 years since the Emperor's reign, but humans began to live in villages and communities in this island nation about 14,000 years ago, during “the JOMON pottery” culture.
(That's 30,000 years ago, if you count the Neolithic period.)
Surrounded by the sea on all four sides, this island nation has a warm and humid climate and is blessed with abundant clear water resources, a variety of plants, and fishery resources.
Since ancient times, people have lived peacefully with nature. They have respected harmony, lived peacefully in groups, and overcome many severe natural disasters such as volcanic eruptions, earthquakes, and typhoons, and have enjoyed the blessings of nature by cooperating with each other in groups based on their wisdom.
The name of the ancient Japanese nation of "YAMATO" or "WA" reflects the wishes and realities of the people living in this varied island nation with a natural environment that differs from that of the continent.
Wow the whole first paragraph is wrong! Every translation you gave. That's certainly something

WA is not a Chinese name. The Chinese of the time applied Chinese kanji to the Japanese pronunciation without the Japanese side's approval, and the original reading sound is "wa" in the Japanese spoken language.
The Chinese intentionally applied Kanji with a bad meaning, so they simply changed the character to "wa" (harmony and peace), which represents the original Japanese meaning.
The name "Hi-no-Izuru-Kuni" (Land of the Rising Sun) is also not the name of the Japanese people's own country. This is a name for the convenience of foreign countries, which was created by continentals geographically west of Japan, based on their location as seen from the side of them.
The Japanese name "Hinomoto" means the country under the sun or the sun itself, but not Land of the Rising Sun.
It is because "the country under the sun or the country of the sun" is exactly the country created by the sun goddess, Amaterasu.
Incidentally, it is said that the origin of the word "Japan," "Zipangu," also comes from the sound of the Chinese reading of the Chinese character "Hinomoto," which Westerners heard.
/Hinomoto (ancient Japanese pronunciation),
/Jit-běn (ancient Chinese pronunciation) (different from today's Mandarin reading).
It seems that the pronunciation of "Jit-běn" as spoken by the Chinese at that time sounded like "Zipangu" to Western ears.
That's great, when are you guys leaving the EU already?
Hey is that a kingfisher?

biomimicry at it's finest
I have a serious reservation about the governments in Asia. In ancient times, this would have been of less concern, but it can no longer be ignored.
I am a Chinese-Japanese-White orphan who was raised in the western USA. I actually never met any other Asian kids! If we did meet, we were just too different to be friends. I used to wish I could marry an Asian girl -- my own kind. (However, I have given up on marriage and relationships). There was something about the Asian-American girl that tells me she does not care about Asia as much as I do -- not like, oh, it's just too different, but rather like there's something disappointing about life in Asia, or even Asian boys themselves...
Well, the other girls must have reservations about some other people, like normal, but to me, I finally connected this sense of disappointment, even anxiety towards Asia to something.
In the west, everyone knows that the legal age of consent is 18 years old, and it's illegal to encroach on minors who are under 18 in any suggestive way, including illegal drawings that depict minors in suggestive light. Aw, heck, even in Asia, I'm sure probably most people think very similarly, if not the same exact thing.
The serious inconsistency between Asia and the west is that in Asia, the legal age of consent is not 18, like it should be -- in Asian countries, the legally defined age of consent might be 15, 14, 13, or even 12. It does not matter how "smart" a kid is, there is a huge difference between being even 16 and being 18. I already agree that being 18 years old, or even older, does not automatically make you "mature enough" to engage in relationships and relations, but for ladies who are looking out for common decency of the youth and the dating world, it is significantly easier to see that potential bachelorettes and bachelors are respected, and not being manipulated or physically exploited when the police-legal line is 18. So if the police-legal line is only 14, it creates problems for us. Think about it: it leaves the door open to exploitative illegal sex offenders/paedophiles who are condemned in the west, but can simply walk into Asia and "legally" commit the same crimes with no substantial legal opposition.
I have listened to Child Protective Services in Asia, specifically Japan, and there are two glaring problems with the country's legal code about youth protections. The first problem is the age of consent is less than the standardized 18 years. It's easy to stop a boy who is too old, like 15, from getting too close to a girl who is too young, like 12, because it's not legal. It's hard to stop a man who is too old, like 24, from getting too close to a girl who is too young, like 14, because even if that man gets the teen girl drunk and commits illegal sexual misconduct on her, the police can't say much in the way of prosecuting the, let's face it, the rapist because the law is breezy and out of date.
In the USA, the law forbids anyone to create or possess depictions or images of minors that are suggestive, regardless of if the minor is fully exposed or not, and -- YES -- regardless of if the minor is real or fictional or otherwise. This brings us to the other glaring problem with Japanese government. No such protection exists, legally. Japanese people were afraid of "raping in the streets", yet "raping in the streets" precisely is all over the web and in certain stores, too. In fact, it almost seems to have contaminated some people's vocabulary. I speak of course of illegal pictures, writings, or media of underage girls depicted in a suggestive way.
It was called "loli" or "lolicon", but I just call it unholy because the term "loli" itself is derived from a book titled "Lolita", which is a book about a teen girl's struggle with a man who committed statutory sexual misconduct on her and was arrested. The term "loli" and even other terms like "nymph" or, in some cases, "junior idol" is already associated with rape, yet men and women have applied the illegal tag "loli" onto the illegal depictions of the minors -- so much so that some people actually seemed to tell others to use the illegal word "loli" to define any culture about juvenile girls or even juvenile girls, themselves. An easy mistake to make, apparently. -___-
I read on Wikipedia (in the talk section of a certain article that should not even exist) that in Japan, there was even an issue regarding school employees who were associating with "lolicon", calling them "lolicon teachers". That's problematic because firstly, that content is illegal, and secondly, schools never hire sex offenders/paedophiles because of the risk to juveniles or at least unnecessary sexual presence that would cause. The word "abhorrent" comes to mind for me.
Obviously, the better majority of people have probably never encountered a problem with such illegal depictions of minors before in their life, or ever will, but if you are on the web long enough, it almost seems bound to pop up. Illegal depictions of minors in suggestive light is forbidden by USA law, but it seems like if you try to do anything about an illegal website that is hosting illegal images, the authorities will just LAUGH IN YOUR FACE and nothing will change.
On a basic level, suggestive depictions of minors should be illegal because it's simply the right policy to put up, as suggestive depictions of minors are disgusting and extremely offensive to girls. On a different level, such depictions should be illegal because the lack of prohibition despite the fact that violations appear flies in the face of ladies and good fathers who believe in and support youth decency protections. The lack of such legal protections is breezy and just leaves the door open to illegal sex offenders/paedophiles to sit around, causing problems, without any substantial legal opposition. The lack of legal protection for us almost might as well enable illegal sex offenders to camp there outside the umbrella of the law and continue to laugh in our faces about their delinquency.
I worry about North Korea because refugees from there used to complain about sexual abuse, including by elders -- and figure this: North Korea does not have any official Child Protections Agency. While we would all love to believe that this is because "such laws and agencies are never even necessary", it is proven that a sex offender/paedophile could easily find a way to walk through and deface youth, and that should already be enough to put up real laws.
In case you haven't figured it out yet, the major problem Asian women have regarding Asia itself is the spotty law, leaving the door open to the unspeakable. While women and some boys are hard at work to "make such laws unnecessary in the first place", is it not clearly better to just update the law to the rightful settings instead of leaving it breezy? The open and almost legally-sanctioned presence of certain rapists in the streets, defacing our youth, polluting the world is a serious problem to us, and therefore to you. The lack of certain youth protections is a major drain of Asian nationality pride and is a root reason that Asia cannot hold its head up high with pride.
