because you immediately refer to early Japanese radar (a WW2 invention) and link to an article about early WW2 radar... and you specifically mention WW2....
There is some reaally good stuff there but it is very American in perspective! What about the Doctor Who theme or Red Dwarf theme for example? (And they forgot MASH)
...unless it was another meaning of the word (or translatable to) "fiddle" and cleaned up through intentional abstruse interpretation by upright (Victorian/American overly puritan perhaps?) scholars?.. that meaning is very, very old indeed...
Hrmm.. I'm not quite sure "read a biography of a run of the mill emperor" is a particularly good way to sell a book. Mind you perhaps that's part of what's wrong with the world and publishing/journalism in general? We only want to read about interesting things (which good and stable governance isn't particularly)
Are they bad asks the question, suggesting it is health related... then personal opinion abounds. Answer: in these terms if someone likes them it is fine.
It was an advancement on the tech of the time, but not the first articulated - was an advancement on how they articulated though (I have a mate with a prosthetic leg so looked into it at one stage :)
ADHD people can have really weird relationships with caffeine, as it is a (mild) CNS stimulant, which is the same class of drug as the stimulants that treat ADHD (help dopamine regulation and prefrontal cortex/executive function). It can actually (mildly) medicate one's ADHD. Also: outside the scope of their claims here about sleep, ADHD people regularly can sleep after drinking strong coffee even when not excessively tired - and actually sleep better than without it - as it helps regulate their brains.
Singing is complicated as studies suggest distances of at least 4.5-5m (15-18 ft) may be required to social distance when singing - eg: https://www.health.nsw.gov.au/Infectious/covid-19/Pages/cho-advice-religious-gatherings.aspx "The only COVID-Safe singing that is permitted is a solo singer distanced at least five metres away from other people and not directly above the audience."(despite claiming 7.5 to 12 foot distances apart, those people look rather closer than that to me, within "their own height" distance - so less than 6 feet - from the nearest other people)
This is not the site you are looking for. This site is for contributers to find neat stuff and share it, saying a few (ideally witty) words that tell the story and maybe add more. Neat stuff. Not self aggrandisement (I note the linked article is your own - the only time that is okay here is when someone is sharing a post about a skillfully craftef physical item they have made) and idly shared rubbish with clickbaity descriptions as you have done previously. And again here.
