Ахиллес и черепаха

Этот парадокс - одна из апорий (затруднений) Зенона. Автором этого парадоксального рассуждения является Зенон Элейский, древнегреческий философ, живший около двух с половиной тысяч лет назад (!).

Ахиллес и черепаха движутся по прямой в одну и ту же сторону, черепаха находится на расстоянии 1000 метров впереди Ахиллеса. Ахиллес бежит в 10 раз быстрее, чем ползёт черепаха.

Ахиллес никогда не догонит черепаху, ведь пока он пробежит 1000 метров до того места, где находилась черепаха, та уже отползёт на 100 метров вперёд. Когда же Ахиллес пробежит и эти 100 метров, черепаха отползёт ещё немного дальше. Это будет продолжаться бесконечно: каждый раз, когда Ахиллес бежит до места, где была черепаха, она уже отползёт на некоторое расстояние.

Сможете ли вы опровергнуть это утверждение?

The transport development has caused objective problems for traffic in cities around the world, including Latvia, and the reason for this is a rapid increase in the number of vehicles.

Promises against statistics

At the end of 2017, according to the report "Global Competitiveness Index", which was annually compiled by experts from the World Economic Forum, Latvia was not ranked among the top 100 countries of the world's rating. (out of 137 countries participating in the ranking, Latvia took 107th place, and Lithuania and Estonia took the 37th and 38th places) Despite this, VAS (State Roads of Latvia) announced that, despite the increase in traffic on Latvian roads, their quality has been improved in recent years.Rolands petersons minicredit

EU assessment - Stable 3 points.

In 2017, 65.1 million euros were spent on the development of the national roads, including 32.3 million for the summer period works, and 32.8 million for the winter period works. In the same year, it was also planned to spend 37 million more, compared with the previous year.Rolands petersons minicredit However, even these investments have not resulted in the average level of road quality in the European Union. According to the latest report, the average level in the EU is estimated at 4.76 points, Latvia, compared to that has been given 3.05 points.

The state of the roads not only hinders the development of the logistics industry but also contributes to the disproportionate level and the pace of social and economic development of the regions.Rolands petersons minicredit The most remote regions of Latvia can develop tourism facilities, offer industrial premises for entrepreneurs, etc. however, if there is no road system to get to these cites, no results shall be expected.

Without the excise tax on fuel, there is no chance for survival

The fact that the change is expected in 2020, the spring of 2018 is said to be the moment to start an intensive work and stimulate actions - change existing arrangements related to the existing tax system (only a third of the tax, paid by road users, are redirected to roads).Rolands petersons minicredit The time when it was possible to pull out a part of the income from tax has passed.

In addition to financing, other necessary support measures need to be introduced: dumping water from roads in certain areas, timely planning, more restrictive control on roads, etc.

Познавательно

Человеческая рука есть одна из первых счетных машин!

Движением пальца. Положите обе руки рядом на стол и протяните пальцы. Каждый палец слева направо будет означать соответствующее порядковое число: первый слева — 1, второй — 2, третий — 3, четвертый — 4 и т. д. до десятого, который будет обозначать число 10. Например, Нам необходимо умножить 7 на 9. Теперь поднимите седьмой палец. Число пальцев, лежащих налево от поднятого пальца, будет числом десятков произведения, а число пальцев направо — числом единиц. Налево от поднятого пальца лежат 6 пальцев, а направо — 3. Значит, результат умножения 7 на 9 равен 63.

Это удивительное на первый взгляд механическое умножение тотчас же станет понятным, если вспомнить, что сумма цифр в каждом произведении чисел таблицы умножения на девять равна девяти, а число десятков в произведении всегда на 1 меньше того числа, которое мы умножаем на 9. Поднятием соответствующего пальца это мы и отмечаем, а следовательно, и умножаем.
