SubscribersHow many subscribers the channel has now. The wave shows subscribers at each point of the period. The change is against the start of the period.4 464▼ 0.6 %−27 for the period
ViewsHow many views the posts published in the period have now. These are not views per day: MAX does not report how many views there were yesterday. The percentage is the change in the daily average: the current period is still running (today is not over yet), so it is compared with the previous one by pace rather than by total. “Was” is the whole previous period of the same length.3 214▼ 44.5 %was 6 317
ReactionsHow many reactions the posts published in the period have. The percentage is the change in the daily average: the current period is still running (today is not over yet), so it is compared with the previous one by pace rather than by total. “Was” is the whole previous period of the same length.140▼ 24.0 %was 201
MentionsHow many times other channels mentioned the channel: links and reposts, excluding advertising posts. The bigger the circle, the more mentions at that point of the period. The percentage is the change in the daily average: the current period is still running (today is not over yet), so it is compared with the previous one by pace rather than by total. “Was” is the whole previous period of the same length.61▼ 18.1 %was 76with a subscription
RepostsHow many times other channels reposted this channel's posts (excluding advertising posts). Reposts are also counted as mentions.

Average post reachHow many views one post gets on average. Only posts older than two days are counted: views of fresh posts are still growing. Points with fresh posts are dashed with hollow dots: the reach of all posts right now, it will still grow.813▼ 22.8 %was 1 053
ERRWhat share of subscribers sees an average post: average reach ÷ subscribers × 100 %. The line shows ERR at each point of the period, the dashed line — ERR of the previous period of the same length. Points with posts younger than two days are hollow dots on the dashed end of the line.18.2 %▼ 5.2 ppdashed line — was 23.4 %

Posts per dayHow many posts are published per day on average. Each cell is a point of the period: the darker, the more posts per day. The percentage is the change in the daily average: the current period is still running (today is not over yet), so it is compared with the previous one by pace rather than by total. “Was” is the whole previous period of the same length.0.7▼ 9.1 %was 0.9
Ad shareWhat share of the period's posts looks like advertising: erid labeling, ad links and other signs. The scale shows the ad load by the quality index thresholds: up to 10 % — low, up to 25 % — moderate, up to 50 % — high, above — very high. A growing share is marked red.5.7 %▲ 3.5 pp
TrendTop — subscribers at the end of each point of the period; bottom — growth per point: green means more subscribers, red means fewer. Above the growth chart — the biggest gain and the biggest loss. MAX does not report how many people subscribed and unsubscribed separately.

Channel scoreA channel score from 0 to 100 made of five parts: audience, growth integrity, ad load, trust and calculation reliability. Each bar shows how many points the part earned out of its maximum. The index is recalculated every night; channels are compared with similar ones of the same category and size.
ReachHow many views the posts published at each point of the period have now (not views per day). The record is labeled; the point with today is paler — the day is not over yet. Average post reach — posts older than two days.
Views and reach

FormatsWhat the feed is made of. Each post has one format, by priority: repost, video, photo, link, text. The bar and percentages show the share of posts of each format; on the right — average reach of one post of the format (posts older than two days), the small bar compares it with the most viewed format.

SummaryTotals for the selected period: how many posts were published, how many views and reactions they have now and the average post reach. Views are the current views of posts published on those days, not views per day. The change is against the same span before the period, if statistics cover it.

Viewstoday — the day is not over yetPoints with posts younger than two days are pale and dashed: their views are still growing.
AdsWhat share of the period's posts looks like advertising: erid labeling, ad links and other signs. The detector is cautious, so the real share is usually higher. The scale shows the ad load by the quality index thresholds. Below — the average reach of an ad post and a regular post, and who the channel advertises (sites that ad links lead to).
What worksPosts of the period with the most views. The bar shows views relative to first place. The preview is the post's image; for a post without an image — the channel avatar. Views are the post's current count.
RhythmHow many posts were published each day of the period (pale bars) and the 7-day average (line): you can see whether the channel is speeding up or slowing down. Today is not over yet, so its average is calculated up to yesterday.
Posts by day

⌛️ В песке можно плавать — достаточно добавить воздух
Лёгкий шарик погружают в песок, а он всплывает обратно, словно в воде. Секрет — в потоке воздуха, который подают снизу: при подходящей скорости он поддерживает песчинки и позволяет им свободнее перемещаться. Такой режим называют псевдоожижением.
Песчинки остаются твёрдыми, а весь слой приобретает свойства жидкости. В нём возникает и выталкивающая сила: предмет с плотностью ниже средней плотности этой среды может держаться на поверхности. Поэтому утопить лёгкий шарик оказывается непросто.
Стоит выключить подачу воздуха — песчинки оседают, и «сухой бассейн» снова становится обычным песком.
Учёные Шеффилдского университета воспроизвели древнеримское стекло, которое меняет цвет в зависимости от освещения, сообщает The Guardian.
Такой эффект известен по кубку Ликурга IV века: при освещении со стороны зрителя он выглядит зелёным, а если свет проходит сквозь него — красным. Секрет в мельчайших частицах золота и серебра внутри стекла. Они избирательно поглощают и рассеивают свет, поэтому до наших глаз доходит разный набор длин волн. Это явление называют дихроизмом.
Само стекло при этом не перекрашивается — меняется путь света. Римские мастера ещё не знали слова «наночастицы», но уже умели создавать материал с удивительными оптическими свойствами.
Пакетик арахиса обычно заканчивает жизнь рядом с сериалом. Но теоретически у него есть и другой карьерный путь — стать сырьём для производства динамита.
Конечно, орехи во взрывчатку никто не крошит. Связь длиннее: из арахисового масла можно получить глицерин, который используют для производства нитроглицерина — взрывчатого компонента классического динамита.
В 1798 году Генри Кавендиш измерил притяжение между предметами в лаборатории. Его инструментом стали крутильные весы: горизонтальное коромысло с небольшими свинцовыми шарами, подвешенное на тонкой проволоке. Когда рядом помещали тяжёлые шары, их притяжение поворачивало коромысло и закручивало подвес.
Проволока сопротивлялась скручиванию. По углу поворота и её упругим свойствам можно было вычислить крошечную силу притяжения. Сравнив её с притяжением шаров к Земле, Кавендиш определил среднюю плотность нашей планеты — а зная её объём, можно было рассчитать и массу.
Сегодня результат такого расчёта записывают как M = gR²/G: нужны радиус Земли, ускорение свободного падения и гравитационная постоянная. Масса планеты — примерно 5,97 × 10²⁴ кг. Чтобы узнать её, оказалось достаточно уловить едва заметное движение лабораторных весов.
