Developing a good sense of how to use your physical intuition for solving problems involves learning the technique of deciding which approach to solving a problem tends to work more "easily" than other possible approaches.

Analyse the following passage and provide appropriate answers An example of a scientist who could measure without instruments is Enrico Fermi , a physicist who won the Nobel Prize in physics in He had a well-developed knack for intuitive, even casual-sounding measurements. One renowned example of his measurement skills was demonstrated at the first detonation of the atom bomb, the Trinity Test site, on July 16, , where he was one of the atomic scientists observing the blast from base camp. While final adjustments were being made to instruments used to measure the yield of the blast, Fermi was making confetti out of a page of notebook paper.

In physics or engineering education , a Fermi problem , Fermi quiz , Fermi question , Fermi estimate , order-of-magnitude problem , order-of-magnitude estimate , or order estimation is an estimation problem designed to teach dimensional analysis or approximation of extreme scientific calculations, and such a problem is usually a back-of-the-envelope calculation. The estimation technique is named after physicist Enrico Fermi as he was known for his ability to make good approximate calculations with little or no actual data. Fermi problems typically involve making justified guesses about quantities and their variance or lower and upper bounds. In some cases, order-of-magnitude estimates can also be derived using dimensional analysis. An example is Enrico Fermi 's estimate of the strength of the atomic bomb that detonated at the Trinity test , based on the distance traveled by pieces of paper he dropped from his hand during the blast.

Enrico Fermi is the father of "solving maths problems we will never know the exact answer to. They are great for getting students to think mathematically and use problem-solving skills. Fermi questions often require students to make reasonable assumptions and estimates about the situation in order to come up with an approximate answer. Students should be reminded of the need to be able to explain and justify what they did when coming up with their solutions. You can also invent your own Fermi questions based on class experiences e.

Fermi questions are named after the physicist and Nobel Prize winner Enrico Fermi. He challenged his students to use estimation, common sense and numerical reasoning to work out quantities that were difficult or impossible to measure. He deliberately posed questions with limited information so that students had to ask more questions. His questions emphasise the process rather than the answer. Fermi showed that by making sensible assumptions, reasonable estimates and using simple calculations, remarkably accurate answers can be reached.

 - Попрыгунчик - древняя история. Стратмор дал маху. Но надо идти вперед, а не оглядываться все время.  - В трубке воцарилась тишина, и Джабба подумал, что зашел слишком.  - Прости меня, Мидж. Я понимаю, что ты приняла всю эту историю близко к сердцу. Стратмор потерпел неудачу.

Лицо его снизу подсвечивалось маленьким предметом, который он извлек из кармана. Сьюзан обмякла, испытав огромное облегчение, и почувствовала, что вновь нормально дышит: до этого она от ужаса задержала дыхание. Предмет в руке Стратмора излучал зеленоватый свет. - Черт возьми, - тихо выругался Стратмор, - мой новый пейджер, - и с отвращением посмотрел на коробочку, лежащую у него на ладони. Он забыл нажать кнопку, которая отключила звук. Этот прибор он купил в магазине электроники, оплатив покупку наличными, чтобы сохранить анонимность.

Сьюзан стало абсолютно очевидно, что план Танкадо ужасным образом рухнул. Он не собирался умирать. Он рассчитывал, сидя в испанском баре, услышать по Си-эн-эн пресс-конференцию об американском сверхсекретном компьютере, способном взломать любые шифры. После этого он позвонил бы Стратмору, считал пароль с кольца на своем пальце и в последнюю минуту спас главный банк данных АНБ.

 Аегорortо. Per favore. Sulla Vespa.

Беккер рванулся. Вобрав голову в плечи, он ударил убийцу всем телом, отшвырнув его на раковину. Со звоном разбилось и покрылось трещинами зеркало. Пистолет упал на пол. Оба противника оказались на полу.

Сотрудник лаборатории систем безопасности не стал выдавать дежурного. - Я поменялся сменой с новым сотрудником. Согласился подежурить в этот уик-энд. Глаза Стратмора сузились. - Странно.
