The OP's whole post is full of misconceptions and just flat wrong statements... I was going to go through it and point them all out, but life's too short. Consign it to pseudo and call it job done.

The Big Bang as we can best imagine (of this least silly of all theories !) had one feature "from nothing" and that was spin. Imagine a marble, perfectly featureless except that it's spinning at infinite speed because it is infinitely contracted. So our singularity in particular was ...well, left biased. I know it sounds wrong to say a singularity has property but that's what they say. This spin direction gives rise to some fundamental properties of our universe that make it sweet for our kind of life. A right-biased universe would not become a happy mirror for our way of life.

Acetone is a simple ketone your own body slices from proteins to be used as fuel. So it's naturally present in the (pre-breakfast?) metabolic state of ketosis because your own body cooks it up from your ham and eggs or whatever. That said, I personally overdosed acetone fumes when swabbing a fibreglass deck for additional coats, and got a a sort of allergic retching reaction next day. The poison is in the dosage.

Hi folks, long time no see, hope all are well.
I have what is probably a very simple maths question: When calculating one's income tax consisting of several different tax bands; is there a neat equation to do this ?
e.g. UK tax. First £12,570 of earnings is not taxed.
Earnings of 12,571 - 37,700 are taxed at 20%
Earnings of 37,701 - 125,140 are taxed at 40%
Earnings above 125,141 are taxed at 45%
I want to input an income figure and see the total tax payable as the result. At the moment I do this on a spreadsheet by a series of nested 'IF' statements, but I have always wondered if there is ..read more

I finally identified the process for coating silica wool (or I could use asbestos) with catalytic platinum. It is fully described on YouTube; search words are "Ostwald catalysis."
Problem solved, thanks to the wonder of YouTube.
BGT, there is another video showing how to infuse carbon with catalytic Pd.

Löyly: Steam, but particularly the steam that is produced when you throw water on the stones in a sauna.
reminds me of the time in Iceland when we were a bit too enthusiastic with throwing water on the heating element, so much so that someone came to check that everything was ok in the sauna
Something just occurred to me: Löyly and Tarjeta go hand-in-hand to a certain extent. Growing up in Northern Minn. , and having taken many a sauna on cold winter nights, I remember leaving the sauna a ..read more

Sounds like a good Inspector Poireau plot(hanky panky behind closed doors in the hotel)

can someone tell me what this means inside my brain
Probably nothing, really. While we sleep, there is an enormous amount of activity in our brains. Experiences from the day before are being reinforced into memory and incorporated with older existing memories. Old memories are being pruned and edited like bushes in a garden. Some connections reinforced, others abandoned. Junk is being cleared out and some synapses cleaned.
Your experience in the dream is just the narrative creation parts of your brain trying to make sense of it all ..read more
