The for loop is a subcase of the while loop.

One theoretical motivation for its existence is that it has the fundamental property that we are immediately certain it will terminate, unlike while loops with arbitrary conditions.

Primitive recursive functions are the complexity class that divides those two.

Atoms exist and last for a long time, while in classical electromagnetic theory punctual orbiting electrons should emit radiation quickly and fall into the nucleus: physics.stackexchange.com/questions/20003/why-dont-electrons-crash-into-the-nuclei-they-orbit

It should be illegal to give someone money to advertise your product.

We should just use tags and upvote-based algorithms.

Advertisement is a form of brainwashing.

TODO find Sergey Brin quote bout advertising being a form of perverting search engine ranking neutrality. In other words, there are neutral metrics to what people find good, like links and upvotes. And then advertising is a way to pervert that to someone's profit.

Sometimes Ciro Santilli thinks advertising should be on-subscription only, but that is too restrictive, e.g. imagine the local business owner who wears a t-shirt of their business.

Resonance is a really cool thing.

Examples:

Perhaps a key insight of resonance is that the reonant any lossy system tends to look like the resonance frequency quite quickly even if the initial condition is not the resonant condition itself, because everything that is not the resonant frequency interferes destructively and becomes noise. Some examples of that:

Another cool aspect of resonance is that it was kind of the motivation for de Broglie hypothesis, as de Broglie was kind of thinking that electroncs might show discrete jumps on atomic spectra because of constructive interference.

Converts RNA to DNA, i.e. the inverse of transcription. Found in viruses such as Retrovirus, which includes e.g. HIV.

Almost always too short superficial where it matters unfortunately, as usual.

Most important application: produce X-rays for X-ray crystallography.

Note however that the big experiments at CERN, like the Large Hadron Collider, are also synchrotrons.

Ciro Santilli is a UK resident. He will register as a "solo trader" (slightly funny legal term) and treat donations that he uses for projects as grants, which pay regular income tax:The rates are given at: www.gov.uk/income-tax-rates and are as of writing:

National insurance is also likely going to be paid: www.gov.uk/self-employed-national-insurance-rates:

Fortunately however VAT does not need to be paid.

The amount that will be declared is the same as he grant amount that was requested, e.g. if 100k USD is requested for 1 year, then 100k USD will be pro-rata declared on that year.

Any remaining donations that don't yet meet specific grant goals will be initially treated as cash gifts which pay no tax. If in the future they are used as grant money after further goal amounts are reached, then they will taxed as grants.

Note however that if the donor is UK-based and dies within 7 years of the gift being given, inheritance tax has to be paid on them as per: www.gov.uk/inheritance-tax/gifts, at a maximum of 32% and going to to 0% at 7 years, so let me know from the afterlife.

Cirists,

Currently, none of the crucial cross file features like \x, \Include and table of contents are working. I was waiting until the above mentioned features were done, and now I'm going to get to that.
