Часто на просторах интернета можно встретить утверждение, что электромагнитные силы (или электромагнитное взаимодействие) очень велики, особенно в сравнении с гравитацией. Я раньше не особо сильно задумывался об этом, а потом решил задуматься, и провести мысленный эксперимент, связанный с тем, чтобы зарядить железо до возможного максимума. Имею в виду удалить или добавить электроны, как это делается с обкладками конденсатора. И далее посмотреть какой будет разряд.

Для примера решил взять железный куб со сторонами 30 см. Я не особо зацикливался на размере куба, хотел чтобы он был не очень большим, и почти не думая выбрал куб со сторонами 30см.
Потом понял, что куб не подходящая форма для этого эксперимента и поменял куб на сферу, которая будет давать такую же массу как и куб со сторонами 30 см.

Имея это, уже можно узнать сколько будет весить такой железный куб или сфера, сколько у него атомов, сколько электронов. Особо на этом останавливаться не буду. Я в простой и понятной форме опишу смысл эксперимента и выводы к которым пришёл на досуге.

Насколько велики электромагнитные силы и насколько важен баланс в природе?
Давайте проведём мысленный эксперимент. Возьмём всем нам хорошо известное железо и придадим ему привычную форму. Для наглядности, пусть это будет куб со сторонами 30 сантиметров, такая форма будет служить хорошим примером.
Но, если хорошо подумать, то со сферой иметь дело будет всё-таки проще, так как у сферы отсутствуют углы, при этом сфера будет лучшим выбором с учетом физики и расчетов. Итак, возьмём железную сферу, которая по массе будет соответствовать нашему 30 сантиметровому кубу. Радиус такой сферы будет 18,6 сантиметров, такая сфера будет иметь массу 212 килограмм.

PC, Xbox, PlayStation 5; Game Freak/Fictions
Game Freak channels a post-apocalyptic reality that reflects our own repetitive erosion cycles, with a fair bit of hand-holding

Most of your time in Beast of Reincarnation is spent collecting last words. You cross paths with robots lying on the ground, who muster whatever energy they have left to provide guidance. These interactions are fleeting. Attempt to talk to them a second time, and protagonist Emma makes their fates painfully clear: “They’ve already passed on.”

The latest detour by Game Freak, the studio best known as the primary developer of Pokémon games, is an action RPG set in a post-apocalyptic Japan. Taking cues from Sekiro: Shadows Die Twice, Final Fantasy VII Remake, and NieR: Automata, you wield the sword of an outcast accompanied by an ever-loyal canine. The pair embark on a taxing and often monotonous journey to defeat the titular beast, which nonetheless serves a thematic purpose to bolster a decaying reality, while reflecting a possible future for ours.

In giving the head coach another World Cup cycle, US Soccer is tempting fate for negligible benefit

Mauricio Pochettino and US Soccer enjoyed their time together.

Or, rather, they enshoyed it, as Pochettino would pronounce it in his thick Argentinian accent, which charmingly carries over when he speaks English.

• Alan Jones paid student athlete he is accused of indecently assaulting $110,000 over a decade, trial hears

Complainant J has spoken about a second visit to Alan Jones’s Fitzroy Falls property, where no alleged assault occurred.

He told the court that before this visit he had done “whatever I could to not go there on my own”.

He said ‘is everything OK [J]?’

While I was being held by the buttocks he reached around and undid my robe and he pulled my underpants down a quarter way down my legs.

He started to wiggle his body so our penises would cross and touch each other.

My heart was racing. I was as scared and nervous as I had been in a long time. It was that feeling when you go into a room you’ve never been in, like a scary room, my heart felt like it was going to come out of my chest.

The defendant placed his hand on my penis and began to squeeze it tight and release it. I was frozen.

I thought if I do this, and I just do it myself, it can be over … and would prevent him from doing it or being near me or touching me. I thought it was the quickest way to make it over and done with, and that’s what happened.

Shares soar as yearly revenue up 93%, even as opposition grows to company’s role in Trump immigration agenda

In a sea of companies reporting mixed financial results this quarter, Palantir stands out. Although Palantir was not immune to the AI jitters that caused industry-wide drops in share prices earlier this year, the AI and analytics company reported that its overall revenue grew 93% year over year to $1.94bn. That’s well over the $1.8bn Wall Street expected Palantir to bring in for the second quarter.

The glowing financials sparked a 10% surge in share prices in the immediate aftermath. Despite growing opposition to Palantir’s work with various governments including the crucial role the company plays in the Trump administration’s immigration agenda, Palantir’s revenue from US government contracts grew 90% year over year to $809m.

В этой статье я расскажу, как создавал скриптовый язык WiremockJs — с нуля и до рабочего прототипа. Поделюсь, что меня подтолкнуло к этому «подвигу», как я проектировал грамматику, с какими ограничениями столкнулся и почему в итоге не стал использовать JavaScript, а написал свой упрощённый диалект. Под катом — ANTLR, парсеры, немного боли и много удовольствия от творчества.

Survey reveals medics were called ‘monkeys’ and ‘dirty foreigners’, and patients refused to be seen by black or Asian staff

NHS radiographers are experiencing racist abuse by patients, who have called them “monkeys” and refused to be seen by black and Asian staff, according to a report.

A survey of 381 members of the Society of Radiographers revealed a “noticeable” rise in instances of overt racism experienced and witnessed by radiographers across the health service over the past 18 months.
