@DarlingtonRoger I hope you enjoy the film, whether or not you decide to include it in your book!

[Nick Hobson @quintic]

@DarlingtonRoger Well, Roger, I think “Educating Rita” is inspirational and funny, with sharp dialogue! I consider it a British classic, in terms of enduring quality, reputation, and cultural significance.

@JP_Mc_C @jamestanton In that case, I'd say the two statements are equivalent, since either implies the other.

Stupendous virtuosity. I couldn't play this fast on air guitar.

@sonukg4india In what reference frame?

The deadly shooting in Minneapolis today was a straight-up execution of a protester by Trump's federal brownshirts.

The thugs wrestled him to the ground. They pistol-whipped him, then shot him multiple times. They murdered him.

The videos don't lie. A man is dead, killed in cold blood. There is no conceivable justification for this intentional homicide. And make no mistake, that intentional, unjustified homicide was committed on behalf of Donald J. Trump.

Trump's militarization of Minneapolis and other parts of our nation isn't about illegal immigration. It's not about enhancing public safety. It's about destroying any sense of that safety—to intimidate political opponents, and to punish dissent. It's about a corrupt, out-of-control regime's effort to provoke citizens in order to justify the violence it desires to commit against them so that it can expand and retain its power.

That is fascism. It is tyranny. It is governmental criminality.

And the ultimate legal check the Framers of our Constitution provided to stop this kind of tyranny and criminality in the executive branch is impeachment and removal of the executive.

Congress needs to do its job.

Now.

Before it's too late.

@Bailyan12 In the order I discovered them:

Chrissie Hynde
Joni Mitchell
Dolores O'Riordan

@Hoainguyen888 An amazing voice, indeed, but the years shown are way off.

[Nick Hobson @quintic]

@KTrain939913 Happy birthday to Noel!

Dolores wrote the music herself for a fair number of their songs, including "Zombie". For many other songs, such as "Linger", Noel contributed the guitar chords and Dolores the melody and lyrics.

@Kenesanca @H0H0v p ₁ + p ₂ should be 5/36 pool/h, not 5/18.

@howie_hua Imaginary numbers don't exist.

@MathGuyTFL Writing 12 as √144, x = 144 × 3/2 = 216

@StudyMaths It's a tie!

@mrB_1970 @Riazi_Cafe_en We're already dealing with quite an irregular rope where some sections burn faster than others! I think it's plausible that such a rope, which could have a non-uniform density along its length, would show small differences in burn rate depending on direction.

[Nick Hobson @quintic]

@mrB_1970 @Riazi_Cafe_en It does make sense, counterintuitive though it might seem!

Consider rope AB with X somewhere along the rope. Burn times in mins:
A to X: 29
X to B: 31
So A to B: 60
B to X: 29
X to A: 31
So B to A: 60

Lit at both ends, the flames meet at X after 29 mins.

[Nick Hobson @quintic]

@mrB_1970 @Riazi_Cafe_en Take two ropes A1-B1 and A2-B2, where An to Bn takes 29 mins and Bn to An takes 31 mins.

Join B1 to B2 and the new rope will burn either end to the other end in 1 hour but only 29 mins when lit at both ends. Or join A1 to A2 and the new rope will take 31 mins lit at both ends.

[Nick Hobson @quintic]

@mrB_1970 @Riazi_Cafe_en Take two ropes, each of which takes 29 mins to burn in one direction and 31 mins in the other direction. I think that's plausible, given some asymmetry of construction.

Then join these two ropes. The new rope would take an hour either way, but 29 (or 31) mins lit at both ends.
