I've never like it when someone 'questions a question' but I'll be guitly of it:

Without a grand unified theory, we aren't even sure what energy is. Also 'infinite' needs to be defined.

Context is needed to answer the question. The answers above make sense in their own context.

As a geologist I say most earthquake pre-detection is unfounded anecdotes.

The previous two postings are correct. These animals have no senses that we do not have other than increased acuity in some of these senses. However, seismologists have experimented with technology that is multiple times more sensitive.

An earthquake is a very straight forward occurrence. The physics are simple. No strange forces happening. We just can't physically measure the variables involved.

I'm in my mid 50's and have been a fitness nut since my teens.

The magic solution is...drum roll....exercise more and eat less!

You can have the best abs in the world and they won't show under a layer of fat. You can do NOTHING about where the fat accumulates (forget the silly yoga crap, etc. for body fat distribution...such things might have their purpose but not for this).

You can burn calories doing weights, running, cycling, etc. Doesn't matter much....just do it and keep at it. Put put down the fork.!

I run about 20 minutes a day 6 days a week and and swim and do weights at the gym 3 days a week. Swimming is a good exercise but make sure you are getting a good work out from it I'm a poor swimmer and exhaust myself quickly (thus working my body)...my wife can do lengths for a half hour and barely exerts herself.

Go to YouTube and watch the best 3 or 4 ab exercises and keep at them. If you get nice abs, you've earned them. No shortcuts. No special diet, devices or whatever. All about bulding ab muscle and losing fat.

Each discipline and each publication has it's own formal and tacit governance.

In 35 years or so contributing to Geology-related papers I've never avoided first person pronouns. As stated by previous posters, clarity is paramount.

We are not automatons and 'our' human perceptions are as much a variable as any other.

an aside... pronouns becomes murkier is when referencing another paper. After stating the paper is it referred to after that actively? ('He shows that or....the study shows that). Again, clarity probably trumps most the time.

A senior doctor emeritus once told me to never push back against an editor unless actual content becomes ambiguous but, when content is an issue, then fight like a charming tiger. "Thanks for pointing out that awkward phrasing...by the way, when I referred to 'whatever', I purposely wanted to use the word.....".

I'm looking for suggestions on acetic anhydride productions at home. Maybe a way of making a home made ketene lamp? I don't have an extensive knowledge of chemistry and this makes the most sense to me.

Not practical.

We use this in a paleo lab and much cheaper more practical to purchase it. Especially of producing via glacial acetic acid which is somewhat tedious to produce in a lab without some dedicated resources. (again we purchase our glacial acetic).

I don't get involved in tracking our use of it but I believe it comes under some restrictive regulations.

The distinction between what is the 'natural' and the 'unnatural' world is artificial....as is the distinction between life and non-life, etc.

Matter and energy are subject to the same principles of the universe regardless of whatever labels we impose upon them.

Humans splicing genes...altering mitochondria, etc. is just chemistry subject to the same physical properties as any other genetic evolution. We are products of evolution and not outside of the process. Anything we do to impact evolution is as much a part of the 'natural' process as any other.

About 20 years ago I was doing some geology sampling on the side of a mountain and then....oops....never did know what happened. Probably slipped and hit my head or conked by a falling rock. Next thing I know there was a a guy unstrapping me from a rescue gurney at a hospital in Yellowknife/ NWT

For the next couple of hours everything was deja vu. The weirdest few hours of my life...I'd have sworn I was watching a rerun of a some reality I had experienced. I saw a local neurologist and then sent south to Calgary to see another. Everything turned out A-OK....nothing beyond some temporary trauma. Not a smidgen of lasting effect (and no more deja vu).

The neurologists was not at all surprised by my vivid deja vu experiences. He said it is not uncommon in brain damage either temporary or long lasting. Everyone has a bit of it but frequent deja vu is not a healthy symptom. If I had more episodes I was to contact him (which was never a necessity).

Bottom line...he said deja vu was a physical phenomenon or short circuit between various parts of the brain. You are temporarily nuts with a false perception of your physical presence.
