The Iliad is a great read, possibly the oldest story on earth, but not those awful old english translations that should stay buried in the library cellar. The original stories were likely an oral tradition and to make them easier to remember were written in poetic verse. You could fill in missing words with whatever sounded right and verses could be added and deleted as the Orator wandered between villages looking for paying customers. Without a good translation the poetic hexameter is completely lost.
The best translation I have ever read of the Iliad is by Robert Fagles and is remarkable in how much better it is over those old versions. He also did a translation of the Odyssey.

The Iliad and the Odyssey include a wealth of astronomical elements, informing about the stars, constellations and asterisms such as as the Pleiades.
The model of the Universe they present is continuous and consists of three levels.
The lower level corresponds to the underworld, the middle one to the Earth and the upper one to the sky.

You can see why Hydrogen is of interest in the aviation industry- energy density per unit volumeis quite low, but it wins on energy per unit mass. I guess the Saturn rocket exploited that (2700 tons fully fueled on the launch pad IIRC). Wonder how much heavier it would have been with Jet fuel?
I think so.
And Kerosene is close to gasoline ( or petrol in UK ). Not even high octane or whatever high end stuff.
The main feature is: Tight specification. It is the same all over the world.

no it's not gasoline at all, it's a more like paraffin.
I have an old camping stove that runs on the stuff. it's quite oily. It's less flammable than gasoline, heavier molecules and all that. In my camping stove the liquid is passed through the flame to pre-heat it and evaporate it before it's burned.

I was quite interested in the idea of time having two dimensions. It's hard to grasp, but the idea of linear Space and Time is easy enough. Spinning Space and TIme makes extra dimensions in a way. So the second time dimension might be time spin to my feeble brain.
Which is why I was thinking about spinning Black Holes;
If you put a spin on a ball and drop it onto the floor, it tends to scud off along the floor, so angular momentum unravels into linear momentum,,,
Charlotte Higgins recommends Fagles too. And Phillip Pullman is some sort of well-known Greek scholar.
Embarrassingly, I have been spending more time on my latest James Lee Burke Murder mystery.

Yes, about kerosene, I was wrong....from a friend I supposed knowledgeable about airplanes.
I used a stove presumably of this kind, in Canada. A terrible contraption, I never used again.

My stove is a collectors item now (it's a British one, probably of the worse kind!) 😀
Once they are up and running you have to pump them up to pressurize the liquid container. If you accidentally tilt the stove over, the liquid isn't vapourized fully and reaches the flame part to create several feet of flame thrower !
In Canada we embrace the cold, pouring maple syrup onto the ice to make candy.

Yes, jet fuel is based on kerosene while fuel for propellor powered aircraft is based on gasoline.
An interesting thing I found when checking that out is that the gas for the prop planes still contains the lead that has long been banned from use in cars.
Without the anti-knock additive there could be fuel detonation problems, which you don't want to occur when you're high up in the sky!
The industry is currently working on how to eliminate lead from the fuel.

One meaning of "burke" is "to murder, as by suffocation, so as to leave no or few marks of violence".
It seems the author was destined to write murder books! 😎
It's funny as anything.
Dave Robicheaux is explaining to his lifetime buddy Clete about the trouble he is in. He is worried that Clete will try to solve it with his usual two fists and a blackjack;
"Clete, they didn't brace me" says Dave.
"Call it what you want. The lowlifes aren't allowed to disrespect the Bobbsey Twins from Homicide. I'll show restraint. I'm completely copacetic and mellow these days, and think only about serene subjects. It's part of a Yogi program I'm in."
Clete then puts the two hoodlums in Intensive care, getting stabbed in the arm himself. Next time Dave sees him, Clete's arm is in a sling. 😀
Sometimes your waffle is useful, Steve!
Today, I've learned a new word. 😎
"Copacetic" means "in excellent order".
You've only just now come across this word? Okay, tell the truth, how old are you?
THE TRUTH! 😡
the jig's up. 🙂

64? You look older.... 😀
Of course you are as old as you feel. Her Maj (95) turned down "The Oldie of the Year" award. TOOTY. Said one is as old as one feels, therefore didn't qualify.

Very fine magazine BTW. Full of useful adverts for Zimmer Frames, Stairlifts, Conservatories and Step-In Baths.

I frequently amaze even myself with my ideas! 😀
Whatever was I thinking of in my 90 degree Butterworth loudspeaker?
Just that I breezed through the filter mathematics and got 90 degrees for the phase difference. So I thought why not turn the tweeter 90 degrees? Must do the same thing. Sounded OK too.
Now I find I was actually experimenting with acoustic Spinning Black Holes! 😱
See, my speaker was creating Spinning Sound Waves! Think of it as being like a V-Twin motorbike turning spin into linear motion.

I need more tweeters! I can see that Nobel prize winging my way already. 🙂
