The Haas / Force India argument is fascinating, and the decision of the stewards may still have consequences. The first key finding is that the stewards ruled Racing Point Force India to be a valid constructor. That means that it builds its own cars.

The awesome role of backspin in swing bowling and dipping yorkers: A thread.

If you've ever bowled any kind of seam in your life, you know that your fingers impart a backward spin on the ball as you release it.

Turns out, this is important in multiple ways.

First up, releasing the ball with backspin gives it rotation about its horizontal axis, much like a cycle wheel.

Much like a wheel, this enables the seam to stay upright (or slanted) without wobbling.

This is conservation of angular momentum.

This is important, because if the seam is wobbling around, it's almost impossible to get swing.

So your fingers naturally put backspin on the ball, which keeps the seam well-behaved, in a line, which is essential to even generate swing.

Turns out, this is not the only way it's important.

Remember when they talk about bowling fuller when it's swinging?

That's to give the ball more time in the air. More time = more swing = more lateral movement. Also, late swing.

Fine. But what does backspin do?

Backspin enables the ball to hang in the air for longer.

Why? Because of something called the Magnus effect.

The Magnus force is due to this backspin, and it lifts the ball.

The ball hits the ground later than it would if there were no backspin.

A simple solution for Welsh rugby, achieved by splitting the administration and control of the community and professional game......1/

The professional game owns the competitions it plays in (so the actual clubs are the shareholders) and form an organisation similar to PRL in order to best serve their commercial interests. Competition & broadcast income no longer flows through the accounts of the WRU but 2/

rather is paid to the incorporated organisation owned by the clubs (with the WRU having a share, so an interest, in that organisation). The WRU share isn't dividend paying, however. That organisation then deals with all aspects of the professional game 3/

from dealing with CVC, to negotiating competition and broadcast income, to sponsors for the Autumn International series, to working with World Rugby on the World Calendar - everything. 4/

From the funds of that corporation, a licence fee is paid to the WRU for the use of the stadium. This licence fee replaces the grant the professional game pays (north of £10m at the moment) to the community game each year. This money, plus whatever the community game 5/

The U.S.-China Rivalry

The US and China are the 2 greatest rivals in the 21st century. It’s American democracy vs Chinese socialism at the level of Roger Federer vs Rafael Nadal in the 2008 Wimbledon Men’s Final. Who’s the better player? American democracy or Chinese socialism?

2/Probably no people have scrutinized American democracy more than China has, the world’s oldest civilization. “American exceptionalism” is under Beijing’s microscope. American democracy has catapulted the US into becoming the world’s greatest superpower in less than 200 years.

3/China, whose momentum will overtake the US in GDP by mid-century, has the same drive as Nadal (who proclaimed Federer was “the greatest player in the history [of tennis]") going against Federer at Wimbledon Final in 2008. Ever cautious, patient and wise, China respects its

4/opponent (as did Nadal) for its achievements. In order to better the US Beijing knows it must be more competitive, up its game and improve its skills. The US-China rivalry is one wherein “iron sharpens iron”. Yet whereas Beijing views American democracy thru an objective,

5/ideologically unbiased lens, the same can’t be said of US Congress, many of whom fear/think China wants to “take over the world” (to wit SoS Mike Pompeo) to “spread communism”. Having 5,000 years of culture, including Confucianism, China has the clearer and more objective view

Dear Steve, I wrote you but still ain't callin',
I left my cell, my pager, and my home phone at the bottom,
I sent two letters back in autumn, you must not-a got 'em,
There probably was a problem at the training ground or somethin'...

Sometimes I scribble addresses too sloppy when I jot 'em,
But anyways, fuck it, what's been up, man. How's Lee Charnley?
Bet he wants you to quit, with that contract they have to honour,
I bought your book for my daughter, you’re a great author,
Next I’ll buy her Sweeper!

I read about Joelinton too I'm sorry,
You ain’t the first manager to have player who didn’t want him,
I know you probably hear this everyday, but I'm your biggest fan,
I even sung your name when we won away at West Ham,

I got a room full of your posters and your pictures man,
I like the shit you did with false 10s too, that shit was fat,
Anyways, I hope you get this man, hit me back,
Just to chat, truly yours, your biggest fan
This is John Carver

Dear Steve, you still ain't called or wrote, I hope you have a chance,
I ain't mad, I just think it's fucked up you don't answer written media,
If you didn't wanna talk to me outside the training ground,
You didn't have to, but you coulda signed an autograph for Steve Stone,
