Can someone explain what razor blades have to do with Moebius strips? Of course, if you used it to split the strip in two along its length you'd get two intertwined loops, which is pretty amazing, but I'm not sure that DB's topology is up to that, so I remain bemused.

It's too klein.

I think it probably is - the reference seemed obvious to me.

Not in my universe, you wouldn't, you'd get a single loop; but YSTCMV
You been near the LHC recently??

EDIT: Just seen "Location: France, near Geneva"
.

It's a fair cop.... With a half twist the razorblade produces one long strip. With a full twist, you get the two linked ones.

Odd that DB didn't pick me up on that himself.

I think DB was intending to slit his wrists.

After subsequent posts, he's probably settled for hitting his head against the wall until he's unconscious.

You're not far wrong. I'm pretty close to unconsciousness, but it's the Aldi Glenbachie that's to blame, cos nobody came up with a razor blade...

Never mind... back to the 'scientists'...

(Admin: bring back the Thanks buttons in off-topic, per favore, bitte, s'il vous plait, ta!)

Of course, I knew what DB wanted a razorblade for really.

Why did you get so grumpy, DB?

I thought we were a broad church here.

What's your problem with a little nerdy fun?

Home advise requested.

You buy a 2 ltr bottle of Coke Cola.

You open it and poor yourself a glass and therefore obviously the bottle is now not full.
Everyone knows that now there is air in the bottle (due to space) the coke will start to become flat.

I thought that if I squeeze the bottle to make sure that the bottle is now full by in effect making the bottle smaller in volume and then tightening the screw top on it.

After about 15 minutes the bottle is full size again.


(1) Is this because the gasses inside have pushed the bottle back out to full size?

(2) Has this action by me made my Coke Cola keep its fizz longer or been worse than if I hadn't squeezed the bottle smaller before closing the screw cap?

My answer (a Bioinformatician not a chemist but i'll take a stab)

Id assume so.

You are probably making it worse. The carbon dioxide that is saturated in the liquid is now out and in the container rather than the coke.

Ah, a less controversial question about carbon dioxide.

Yes.

Yes. Jimmy Bee is correct.

Apart from gas, it is known that Coco Cola is 50 times more acidic than
ordinary tap water, and we give it to our children!

It has a pH of 2.5 ?

We give them oranges, too...

They get new teeth after a few years anyway, so why worry about it?

And the gastric acid in your stomach is maybe 10 times more acid than that, so ... nothing to worry about on that score.

Would the volcano stop erupting silica and simply spew out lava if the top vent was made much wider?

I was thinking of suggesting the European air forces could bomb the volcano, as maybe after 66 years they could do with some practice?

airspace is closed

Slinky + Escalator = Infinite fun?

Um........no.

Airspace is open to military aircraft. Are you qualified to say no?

Not regarding the airspace question, no. With regard to making the hole wider, yes. Unless you wanted to dump multiple large yield nukes in the hole and hope for the best.

Thank you for the, for me, surprising answer.
