You probably have seen this game on TV and wondered what the hack was this unsual game ws about. It is competed in winter Olympics too. We saw the game being competed between a Mobil Canada team and a team from anoter oil company is Calgary when we were up in Calgary in 1988.

Ever since then I like to watch this most unusual and slow game on TV in the winter and appreciate the skills, the strategy, the precision and the seriousness of the sweepers and throwers of the team.

Do you want to know what the “Most Mysterious Question” about Curling is?

Read the artical and see how these scientists did it.

A clue: it involves 9 variables.

It is the law, stupid. October 12, 2017

What’s great about the United States is that all U.S. citizens are protected by the law equally; to a certain degree unfortunately. 

America has a sound legal system and the law is carried out to the fullest in many cases. Of course, rich people have a leg up in front of the prosecutor, juror or judge because their money can buy the brightest and the sharpest lawyers to defend them. Lowlifers get public defender fresh out of the law school if they are lucky.

Well, I have been told many times that all Americans have the right to freely express themselves. 

So, is “taking a knee” protected by the constitution?

Here is the definitive answer from judge Andrew Napolitano. Take a few minutes and get the answer yourself.

The next questions are: 

  1. Can Jerry Jones of Dallas Cowboys compell his players who have “taken a knee” to stand?
  2. If these players defy Jerry Jones’s order to stand, can they be sidelined or penalized financially?


FYI, here is Supreme Court’s opinion on freedom of speech:

At least this was my observation when my wife and I lived in NYC on 2nd avenue one block north of Houston street.

I do have a partial answer to my own question and it was based on another observation of mine in NYC:

Near Laffayette and Broome close to SOHO.

The answer: they rather work with their own hands instead.

3% vs 2% September 30, 2017

We’re talking about the growth rate of American’s economy in the next 10 years.

Trump, well his underling, said that America’s economy will grow 3% on average for the next 10 years after Republican’s tax reform is enacted as law.

Source: Bloomberg.

You see, Republican and Democrat are ‘兩個烏鴉一般黑’, they are ‘一丘之貉’. They use this kind of financial trick to tell American citizens that even though their program, be it Obamacare in 2009 or tax reform in 2017, will increase deficit, but the resulting higher economic growth will generate enough taxes to make the new program budget neutral: a term you will hear repeatly before the end of this year.

Do you know the impact on American’s national debt if the economy grew 2% instead of 3%? 

About $2 trillion. And that’s assuming the U.S. won’t fall into a recession and no funny accounting gimmicks.

Last year, the U.S. federal deficit was $590 billion but the national debt rose by $1.4 trillion; a whoppying $810 billion difference.

Why? Where did $810 billion go?

Well, check out this link below and read yourself.

Allow me to give you some highlights to get you started:

Do you know that government’s borrowing to make student loans and repairs on highways and bridges aren’t classified as deficit? These items are ‘investments’ so that they don’t count as deficit. In addition, the U.S. government had to borrow some money to pay for social welfare recipiants because the government didn’t collect enough taxes from FICA deductions to pay for social welfare benefits: social security, Medicare and ACA. There are more in the article if your blood pressure is under control.

A warning: as powerful as America is, all bean counters working for the federal government couldn’t figure out where $82 billion went.

This is your America.

Quantum entanglement: of photons,墨子 and teleporting July 15, 2017

A quantum leap by a team of scientists in Tibet, China: a first in the world.

But, can you even comprehend that China is working on a fundamental scientific project like this one?

Well, it does have practical application: quantum cryptography. It means, in plain english, unbreakable codes.

Terrifying unexplained mysteries of deep space

Don’t forget the Great Attractor.

Terrifying indeed. But, you don’t need to lose sleep over it.

Trump will keep you up in the night anyway.

Ngari No. 1 February 18, 2017

I bet that you don’t know what Ngari is. Of course, if you haven’t heard of Ngari, you probably have no idea what Ngari No. 1 and Ngari No.2 are.

Well, Ngari is an area in western Tibet and it is world-renowned as the Roof of Tibet. It is a barren plateau of 133,205 square miles roughly 17,220 feet above sea level. Its Chinese name is 阿里 (ā lǐ).

Ngari is famous because it is the site of China’s first gravitational-wave observatory, the highest in the world. 

Ngari 1 is the site of the first phase of the telescope designed to gather data on primordial gravitational waves in the northern hemisphere. It will be operational by 2021. The second phase, Ngari No. 2, will consist of a series of telescopes installed about 20,000 feet above sea level.

Of course, Ngari was chosen for the newest telescope because its high altitude, clear sky, minimum light interference and low human activities, ideal for studying the ripples in the spacetime in cosmic light. 

The Ngari project is sponsored by three institutions: Institution of High Energy Physics, National Astronomical Observatories and Shanghai Institute of Microsystem and Information Technology.

Gravitational waved was first predicted by Albert Einstein in 1916. They are ripples in the curvature of spacetime which is the fabric of the universe.

These waves are actual physical ripples which stretch and squeeze the space they exist in. 

For 100 years after Einstein first predicted the existence of gravitational waves, none of this elusive waves have ever been detected until February 11, 2016. Two groups jointly declared the detection of the wave produced by the merge of two black holes 1.3 billion years ago. Now the scientists around the world are racing to capture and study the cosmic waves.

On December 13, 2016, the Ngari No. 1 project was officially lauched by the China Institute of High-Energy Physics, a division of the Chinese Academy of Science. The project is aimed to create a highly sensitive experiment on primordial gravitational waves. It will likely be a stepping stone for other cosmological studies such as the evolution of the universe, dark matter and dark energy. 

But, let’s face it, China is new to this field and it has a rather steep learning curve to climb. Close corporation with top scientists around the world is definitely needed.

Actually, what is surprising to me is that China is in the project and is committed to build the telescope in the first place.

I do have a few questions but I don’t think I’ll find any answers in the public domain:

Why did China even participate in this kind of fundamental research at all? 

What did China expect to get out of from this project? 

What are gravitational waves or ripples in the spacetime to China?

Which government official approved this project and what was the total cost of the entire project?

Will China’s participation in this project make any meaningful contribution to the gravitational waves and related research?

Will Ngari No. 1 and Ngari No. 2 find any gravitational waves?

What other cosmology projects are on the drawing board in China?

What’s before the “Big Bang” and should we care about it at all?

Been to a few shows when our kids were little. Enjoyed the shows back then.

Too bad that the show has to go. Sign of the time because the show wasn’t making money or the company can’t fight the environmentalists?

About two months ago I saw a commercial right in front of my eyes while I was washing my hands in a bathroom. The bathroom was located at a department store called Viewshow in Xinyi District of Taipei, Taiwan.


I said back then that one of those days you might be able to watch an ad for a restaurant while you are taking care of your business.

Lo and behold, my causal prediction became realty a week ago when we went back to Viewshow for dinner.

There it was: right there in front of me. 

Thank heaven, it wasn’t a commercial for food at least.

Make your own predictions if you dare. I am not going to because I might be right again.

I’ll keep you posted.

What’s that? October 8, 2016

On top of that building in the middle is what seems to be a high power laser gun guarding the building 24/7.

But, is it? 

Probably not.

Do you know what it is?
