Re: Неверные утверждения...

Привет!

[On a historical note, while reading Christopher Hibbert's George III: A Personal History (p. 194) during the Christmas 2000 holidays, I learned that the King, known for his personal interest in the sciences, was shown a demonstration of the simultaneous fall of a feather and a one guinea coin in an evacuated tube (p. 194). The demonstration was performed in 1761 by one John Miller, assistant to His Majesty's Mathematical Instrument Maker, George Adams. The experiment is known as the Guinea and the Feather and has been seen by countless physics students over the centuries. The Adams Guinea-and-Feather apparatus is on display at the Science Museum of London along with the Adams air pump with which it was evacuated. Photos by Mick Hyde.]
[AFJ Editor David Woods calls our attention to the following from the Apollo 15 Preliminary Science Report: "During the final minutes of the third extravehicular activity, a short demonstration experiment was conducted. A heavy object (a 1.32-kg aluminum geological hammer) and a light object (a 0.03-kg falcon feather) were released simultaneously from approximately the same height (approximately 1.6 m) and were allowed to fall to the surface. Within the accuracy of the simultaneous release, the objects were observed to undergo the same acceleration and strike the lunar surface simultaneously, which was a result predicted by well-established theory, but a result nonetheless reassuring considering both the number of viewers that witnessed the experiment and the fact that the homeward journey was based critically on the validity of the particular theory being tested."]
[Journal Contributor Joonas Helminen notes that the estimated height - 1.6 meters - from which the hammer and feather were dropped is in error. Although the important part of the experiment is the fact that these two objects of very different weight experienced the same motion, for completeness we offer the following. If we concentrate on the hammer, Helminen has stepped through the mpeg clip and finds that the time between Dave's release of the hammer and its impact is 36 frames. The framing rate is 30 frames per second, giving a fall time of 1.2 seconds. We have two separate estimates of the height. Helminen estimates the height as 120 cm and writes, "My estimation was simply from thinking how far you would bend forward with the PLSS on your back and from noticing how Dave did not hold his arms straight out parallel to the ground. I am just below 180cm tall and, when put myself in the same posture, 120 cm was a close estimate of the height of the bottom of the hammer head." An independent estimate is provided by the known length of the hammer, which is 39 cm. By noting the point on the ground where the hammer hits, a measurement can be made on the image of the initial height of 2.9 hammer lengths or 113 cm. We can use these estimates to calculate the strength of lunar gravity (grav = 2 * height / time squared). A height of 120 cm gives 167 cm per second squared and a height of 113 cm gives 157 cm per second squared. Because of likely errors, particularly the height estimates, both are consistent with the actual value of 163 cm per second squared.]



Когда они выложены - сказать трудно, скорее всего, не ранее 1996 года, более вероятно -между 2000 и 2008 годом.


>Мой вывод таков (можете не соглашаться, конечно): А.И. Попов давно уже убедился, что люди на Луне вправду были. Но продолжает почему-то настаивать, что дескать, "нет доказательств". Вопрос – зачем?
Фактически, вы обвиняете Попова в недобросовестности. Как обычно, лишь "читая в сердцах".
По-моему, это стыдно.
