I have no medical qualifications, so take this for what it's worth, but I was told by a psychiatrist specialising in child development disorders that excessive hand-washing is one symptom of Asperger's syndrome.

This has nothing to do with 50/60 Hz ripples, the point of having a personal power transformer is to isolate from high-frequency noise.

Audio amplifiers already contain transformers, large capacitors, and rectifiers.

Thank you for the link. Could people who have studied it answer whether it is similar to the code here?

Python did not have a genesis at Google. It existed before Google did.

JavaScript was written by Brendan Eich as the browser-side scripting language for the Netscape browser, originally based on Lisp I believe. It was not meant to be a joke.

Science (academic work) is a career for many people, rather than a vocation. Rewards include high status, stable income, opportunities to travel, long vacations, etc.

You can say it's not science but most "scientists" are just normal people with everyday priorities, rather than Einstein-like people who go on doing science work while working as patent clerks.

I am curious how many people the author has taught mathematics to.

It doesn't seem a good idea to jump into writing a textbook teaching mathematics unless one has experience of teaching mathematics.

But the author makes the very point about early failures of programming, due to lack of experience, so perhaps he can supply information about what his pedagogical experience consists of.

Teaching other people is a craft, similar to programming or mathematics, with its own necessities.

The thing I can't understand is why on earth would anyone want to leave an organisation like the European Union?

Same old, same old:

People have been trying to set up web-based academic publishing for at least twenty years, and they've failed. The obvious explanation is that it does actually cost money to publish academic research.

It's testing how antimatter and matter interact gravitationally.

It isn't possible to test how antimatter and antimatter interact gravitationally, because only single atoms of antimatter can be produced, and single atoms don't exert enough gravitational pull on each other to be measurable.
