Airplane Industries May Dismiss Bernouli’s Principle
Even flat wings had existed since the beginning of aeroplane industry. And it worked.
So what’s the point for modern aeronautics industries to shape such ‘modern’ wings based on Bernouli’s Principle? And what’s the point to teach Bernouli’s Principle at universities?
Wrong Common Sense of Circumference
When 360Β° accumulation of straight lines is regarded as the circumference, the consequences are:Β You’ll get the right circular area, BUT unfortunately you’ll get the wrong circumference:

The points:
Examine the tiny angles, you’ll find the difference between pi’s arc and the ‘neck’ doesn’t make sense.
Example: angle=1Β°, r=10000 >> on the inner limit of 170s meters, how come the difference between inner the limit and the arc as far as 2.2 millimeters can lift up a neck as high as 38 centimeters?? Impossible.
How ever, for circular area, series approach will give you the value of pi by figuring out between the inner limit and outer limit.
But for circumference, there will be additional length from 2pi.r.
My proposition is 3.17157. Some mathematicians lately mentioned 3.16 something.
Let’s see which one is correct. Time will tell.
Otong, Lead Vocalist of Koil Band : Unique Mixture of Personality

So far I don’t know much about Koil Band, but its lead vocalist’s interview is always interesting and no boring.
He claims “having no friend”, Β and to me he seems to be honest, smart, … at the same time: “naive”. ππβπππ
This guy always destroys the guitar on stage, as well as gives a new guitar to one of the audience. Frequently got cheated in business and got broke, yet he is ‘addicted’ to give money to anyone misfortune that he found personally. ππππππ
Whitney Houston Rules
Every female singer on earth loves to sing her songs.
Indonesian Idol >>

He Said That’s a Five Stars Hotel Food : only ~ 0.7$ ~
Even me is also surprised with such cheap price.
As the capital city, Jakarta attracts best foods all over the country as well as the world.

Tiara, one of the candidates singing Whitney Houston’s song: “One Moment in Time”.
A bit risky to sing a legend’s song. But Tiara was not bad at all. The audience still enjoyed her performance with standing ovation.
The same was for Claudia when singing Whitney’s “I Have Nothing” in The VoiceΒ of Germany.
Both are very young singers and still have a chance to improve their singings to be as perfect as possible.
For Claudia, I prefer her singing “Never Enough”.
Good singing is when there is ‘spirit’ in it. The voice is able to penetrate the strings of heart.
The nice thing watching a singing competitions is: the ‘goosebumping’ by a few highly talented singers such as Tiara and Claudia. π
God Bless Germany
Singers Battle between Indonesia vs The Philippines is always amazing.
Enjoy πππ
By the way, Claudia won The 2019’s The Voice of Germany.
It’s surprising. There is honesty there!
German people and juries..
you’re the Real Champion!
