World markets dive as Trump sparks trade, North Korea worries

Global stocks sank Wednesday after US President Donald Trump said he was not satisfied with talks that are aimed at averting a trade war with China. Equities were also dented by poor eurozone economic data, and as Trump cast doubt on a planned summit with North Korean leader Kim Jong Un. “Trump (is) continuing to drive uncertainty over global trade,” said analyst Joshua Mahony at trading firm IG. “European markets are following their Asian counterparts lower, as a pessimistic tone from Trump is compounded by downbeat economic data,” he added. Markets had surged Monday after US Treasury Secretary Steven Mnuchin and Chinese Vice Premier Liu He said they had agreed to pull back from imposing threatened tariffs on billions of dollars of goods, and continue talks on a variety of trade issues. However, Trump has declared that he was “not satisfied” with the status of the talks, fuelling worries that the world’s top two economies could still slug out an economically pain...

How To Become A Mathematical Genius Overnight.

Everyone’s out of school and so this post is not strictly about game theory but rather a case study in strategic thinking.
For 7 years I was called very few names online. Then one day my math video Multiply Numbers By Drawing Lines went viral and got over 1 million views. Suddenly people were talking about me on YouTube, Twitter, and Facebook. I was not a nobody; I was called a “math genius.”
I am, in fact, not a math genius. I am good at math and I’m a good student. No one ever called me a math genius because I studied math. What I learned from the experience is how to earn the public title of “math genius.”
And I want to share what I’ve learned because the world needs more math geniuses. You too can become a mathematical genius overnight. And you don’t have to be that good at math either.
So what’s the magic formula? Let me cut right to the chase.
The secret ingredient to being called a math genius depends on one factor: publicity.
If you can demonstrate an unexpected mathematical skill to a large audience, people will suddenly call you a math genius.
Is it really that simple? I decided to check out the evidence. I went over the last 10 years of US news headlines, from the Google news archive, for the phrase “math genius.” There actually weren’t too many examples. A few of them applied to recognized mathematicians, who actually are math geniuses.
But the rest of the examples were similar. The phrase “math genius” was applied to a combination of an unexpected math skill that was revealed to a large audience.
I’ve selected three stories to illustrate the point. You can learn from these examples, and you too can become a math genius in the media’s eye.


1. Ryan Fitzpatrick’s Son: Mental Math
On November 30, 2014, the Houston Texans won a game. The quarterback Ryan Fitzpatrick threw 6 touchdown passes and everyone wanted to hear his press conference. The Harvard graduate took the moment to deflect praise and instead be a proud father.
Fitzpatrick brought his 6 year old son Brady on stage. Then, he asked a reporter for two numbers in the 90s. Watch him do the math and earn the title of “math genius.”
(If that video doesn’t work, watch the clip at NFL.com.)
In fact, there is a trick to multiply two numbers in the 90s. You can learn the trick in this video.
Notice that math knowledge itself is not a path to becoming a math genius, it was demonstrating the skill to an audience.
The easiest way to becoming a math genius is to do some mental math tricks. You’ll be a hit at parties and when you get a press conference you can stun people by doing math in your head.
(Incidentally, this is as good a time as ever to plug my new book, The Best Mental Math Tricks. It includes some killer tricks that are sure to impress and make you look like a math genius.)
2. John Urschel, NFL Player: Math Researcher
Can you name an Offensive Lineman on the Baltimore Ravens? Before this year only diehard fans knew about John Urschel. Now he’s known as a “math genius.”
Urschel majored in math in college, helps teach math to grade school children, and he reads math in his spare time.
But that alone was not enough to make him a math genius in the public eye. The catalyst was he took a stance on a controversial topic. This year a few NFL players retired citing health concerns, including 24 year old Chris Borland from the San Francisco 49ers.
Urschel wrote a piece in the Players Tribune about why he plays footballin spite of the risk of concussions. This suddenly raised huge attention and everyone learned he has published math papers.
The lesson is that even being in the NFL may not be enough publicity. Urschel only became a “math genius” when he also took a stance that got attention.
3. Chris McKinlay: Math For Love
It’s really hard to become a tenured math professor. You have to study math at the university level and get good grades. Then you have to get accepted into a PhD program, at which point you have to pass a preliminary exam, which perhaps 1/3 of the students do not pass. Your reward is the privilege of writing a thesis with original research, which, if accepted, earns you a PhD.
You’ve got your PhD, but now the fun really begins! You now begin postdoctoral work, where you compete for the limited number of tenured professor positions.
You could argue anyone that is a postdoc in math is knowledgeable to pass the bar of being a “math genius.” But to earn the title in the media, you have to do something else.
Chris McKinlay used his math and programming skills for dating. Specifically, he was frustrated at the results from the online dating website OKCupid. So he programmed an algorithm to improve his odds of finding a good match.
The story was covered in Wired–note that he’s called a math genius! The story is actually a bit strange when you read about the details of how he harvested the data.
No matter, applying math to love and the popular dating website OKCupid–which is a larger platform–earned him the title of “math genius.”
Conclusion
There is a hard way to becoming a math genius: actually study math and win a Fields Medal, a MacArthur “genius” grant, or get bestowed the new Genius grant. That takes extreme dedication and is why “math genius” is applied to people like Manjul Bhargava, Maryam Mirzakhani, or Terence Tao.
But why do that when you can try to get rich genius quickly?
If you’re above average at math, then figure out how to get on a bigger stage. Play a sport. Learn video editing. Get into politics. Become an actor.
The above examples illustrate the key to being a “math genius” is to show an unexpected math skill on a large stage. No matter what math skills these people possessed before, it was only after they demonstrated an unexpected application on a large stage that they got called a “math genius.”
There are a couple of unusual cases worth noting. One is Jason Padgett, a “woman chaser” who turned into a math genius after being beat up in a bar fight. I have not yet read his book, but it seems his brain injury gave him savant abilities.
Another case is a 10 year old girl Esther Okade. The British-Nigerian is starting university study and evidently has strong math ability at a young age.

Saturated Fats vs. Unsaturated Fats.

Saturated Fats vs. Unsaturated Fats Diffen  ›  Food  ›  Diet & Nutrition The human body needs both  saturated fats  and  unsaturated fats  to remain healthy. Most dietary recommendations suggest that, of the daily intake of fat, a higher proportion should be from unsaturated fats, as they are thought to promote  good cholesterol  and help prevent cardiovascular disease, whereas an overabundance of saturated fats is thought to promote bad cholesterol. However,  a few studies  have found that little evidence for a strong link between the consumption of saturated fat and cardiovascular disease. Note: It is technically more accurate to call saturated and unsaturated fats types of  fatty acids , as it is specifically the  fatty acid  found in a fat that is either saturated or unsaturated. However, referring to fatty acids as fats is common. Comparison chart Saturated Fats versus Unsaturated F...
