So we are swine then? What was it you said about how you would never be rude?

These deflections are obvious Vixen. We all know you can't answer the question, and the pretence that you can you just don't want to is pathetically obvious. You don't know what the null hypothesis is and the fact that you're not the smartest person in the room is eating you up inside.

Prove me wrong. Shut down the person who is claiming you don't know what you're talking about and have been humiliating yourself in this thread. What is the null hypothesis and how is it used in science. You're a "scientist". Explain this exceptionally basic scientific concept.

OK

In inferential statistics, the null hypothesis (often denoted H0)[1] is a default hypothesis that a quantity to be measured is zero (null). Typically, the quantity to be measured is the difference between two situations, for instance to try to determine if there is a positive proof that an effect has occurred or that samples derive from different batches.[2][3][4]

Done.

What positive proof have you?

So far none, but I allow the opportunity, unlikely as it is.

Hhmmm. Back when I I was teaching many years ago I made it my business to teach an understanding of physics. So did all of my colleagues.

Wherever you claim to have rocked up as a snotty teenager appears to be an odd FU partial "collage" as some idiot claims in a different thread.

No, you weren't. I have read the report you yourself provided the link to.

IT DOES NOT CLAIM THAT 700°C IS NOT ACHIEVABLE OUTSIDE A LAB.

Pleases stop saying it does.

I have no idea why you posted any of that in response to my post.
Did you quote the wrong person?
Did you misunderstand my post?

Does welding cause the following to happen, since you are so knowledgeable:

  • • the appearance of parallel shear bands (Neumann bands)
    • changes respectively destruction of the cementite lamellas in the perlite
    • hardness increase
    • plastic deformation in the micro area (wavy arrangement of the structure parts)

A simple yes or no will suffice.

I don't know the answer. However, as an experienced professional proofreader of scientific papers, I do know that "changes respectively destruction of the cementite lamellas in the perlite" is not a grammatically correct or coherent description of a property or a change of properties of a material. Most likely, the first two words belong to some other list item or heading and were erroneously attached to the phrase beginning "destruction." Which strongly suggests that the entire list was copied and pasted blindly without comprehension.

Secondary school science teacher here, and also a former accountant. You are not a scientist. The fact that you might practice a discipline with the word "science" in its name doesn't make you a scientist, as the word is commonly understood by the overwhelming majority of native English speakers.

As an ROTC cadet, I took four years of "Military Science". I guess I'm a scientist, too! Imagine a cute image posted below.

If the flame in a typical gas stove hob is 1900°C why does it take 8 minutes to boil one pint of water to 100°C?

Because temperature is not energy. You have to transfer enough energy from the burning gas to the water to raise the temperature to boiling. It takes a lot of energy to raise the temperature of water by one degree C.

You might want to learn about specific heat capacity before you make a fool of yourself again.

Evidence says not likely.

ETA - my strikethrough added.

If you studied physics for five years in secondary school, that would be up to O level, which should include the thermal properties of matter including specific heat capacity and how to calculate temperature rises due to heating.

This is exactly why your dwelling on your own academic qualifications and your insistence that you are a scientist based on some courses you took 40 years ago is so abnormal. Did you once dream of becoming real scientist?

The only persons dwelling on it are yourself, JayUtah and 'MarkCorrigan'. A scientist is neither good nor bad. Just as an artist is neither so, either.

You are not a scientist though. Stop making claims that are manifestly not true and we won't bother you about your making claims that aren't true. It's a wonder how that works.

Your claim, stop handwaving and back it up. Answer my question "scientist". What is the null hypothesis and how is it used?

Incidentally, why do you put my handle in scare quotes like that?

It's a translation from the German, which can trip up English speakers in respect of sentence structure. It is from this web page here.

My question was a rhetorical one to help enable GlennB consider how misconceived his view is that the heat of a mig welder of 6K° is equivalent to heating up steel to the same temperature.

I am sure you are right but you clearly haven't been following the conversation if you thought I was asking GlennB for the answer to a simple question.


As if I would need to ask GlennB how water boils!

I take it it is an assumed name? Hence the quotation marks. Take it up with JayUtah as he is the one who insists one must be a licensed engineer to discuss the Estonia sinking. I have never claimed any expertise.

I never said I had A-Level Physics. Stop lying.

A quick google tells you: The hotness of the gas stove flame ranges from 600℃-3000℃ depending on two important factors. One of these important factors is the amount of energy beings released from fuel combustion, while the other important factor is the availability of pure oxygen rather than air to ensure complete combustion.

Gas welding does use pure oxygen.
