No. Cavity wall insulation and polystyrene sheet internal insulation show that you are wrong. What you see on the outside is often brick. And bricks are lousy insulation. They are structural, not thermal. Some of their buildings are https://www.mountain-forecast.com/peaks/Mauna-Kea/forecasts/4205 But that doesn't matter much. Then why did you introduce it? Do you really think that those who live in well insulated houses don't want to pay smaller bills? The current issue with UK energy bills isn't insulation. It's profiteering (aided by a corrupt government). That's probably a bit beside the point.. None. They died because some bastard wanted to save money and broke the law to do it. We have known for decades that you use fibreglass if you are worried about fire. If you go back a bit before that we used asbestos lagging. My 19th century house now has about 15 cm of fire retardant polyurethane foam in the roof. What evidence do you have?

No. In the UK -10 is equivalent to -10. That's the point of having a standardised scale.

That's a little like assuming that people have no internal organs because all you see is skin.

They usually use PTFE.

BDDE isn't going to be very stable- because of the two epoxy groups. It's likely to forma a mess of different product when heated. But "stable" is a difficult thing to define. Stable for how long?

Seems an odd place to start. What are you trying to achieve?

It is certainly possible. https://www.chemeng.uliege.be/upload/docs/application/pdf/2020-06/article_publication_ethanol.pdf but the search fore renewables means that the opposite reaction is actively being researched. https://onlinelibrary.wiley.com/doi/10.1002/cben.201600025

Sulphuric acid meets the criteria you gave but it may be unsuitable. If you tell us what you are seeking to do we might be better able to help.

It isn't. Why did you think it was?

Why this should be the question? Because the difference between a show of hands and a secret ballot is not what you vote for , but what others learn about you.

It is important to recognise that they might be right. For the same reason that most people earn less than the average salary. I think the question should be "would you like others to think you are stupid?".

We already thought that number was possible.

I understand that I can write "two up arrow up arrow four is 65536". Which letters didn't you like? More generally. The Berry paradox is a self-referential paradox arising from an expression like "The smallest positive integer not definable in under sixty letters" (a phrase with fifty-seven letters). https://en.wikipedia.org/wiki/Berry_paradox

Probably not because we can get creative about the way we express them. https://en.wikipedia.org/wiki/Knuth's_up-arrow_notation

Buffer solutions and/ or a pH meter. But you will run into a problem. You can set up a calibration and draw a graph of absorbance vs pH. But it will depend on the concentration of the dye as well as on the pH. It is difficult to be sure that you always have the same concentration of dye. Most dyes are a bit unstable and a lot of them are not supplied as pure materials, but as crude products containing salt etc. So, you would have to make a fresh calibration for each set of samples. If you are going to do that- and use a pH meter to do it- you might as well just use the pH meter to determine the pH of your sample. But there's another pitfall in this analysis. pH meter probes always carry some buffer into the solution which you are trying to measure. And that changes the pH of the sample. To measure the pH of very dilute materials (like drinking water or even river water) you need specialist equipment. I suggest that you contact the people who make pH meters and ask for their advice.

What were you expecting? Why would you post that in a thread where someone has actually done the experiment and told you that there is " LITERALLY NO REACTION"?

Not if you apply it to people who are dead. Equally interestingly " Guinness retired the "Highest IQ" category in 1990 after concluding IQ tests were too unreliable to designate a single record holder." From https://en.wikipedia.org/wiki/Marilyn_vos_Savant Fundamentally, IQ is a measure of how well you do in IQ tests and it measures nothing else.

Yes. So? Here's an interesting observation. The IQ test was designed to identify school kids who were struggling with education in order that they could get extra help. But the people you see on the internet asking about IQ are neither schoolkids, nor do they have cognitive / learning issues. They just sound like it.

Yes. And he's quite honest about the fact that they are illusions; not real. And would you accept this as proof of a flying pig? or do you understand that video is quite easy to fake?

"Will science ever stagnate and come to a halt?" Most Friday afternoons

I'm fairly sure that sodium bicarbonate will float in methylene bromide, but calcite will sink.

Yes there is. The reason is science. Sure Did you really think it was magic? Would you like to buy Tower Bridge?

I think they look cute. But I still don't think any of this really counts as a wheel.

The seeds are alive, and they travel on "wheels"

So, aside from the issue of connecting blood supplies / nerves etc, and the fact that wheels are only useful if you have a "road" and the challenge of finding a use for half a wheel? ... tumbleweed...
