Is "colleagues asked hundreds of former high school students to look back at th yearbooks and see whether they could remember the faces of their classmates. What tho 5 discovered is (ア)proof of the power of human memory. For decades after graduation t. memory of fofmer students for the faces of their classmates was nearly undamaged. Evos after nearly half a century had passed, the former students could still recognize seventw three percent of faces of their classmates. But when it came to names, Bahrick found, memories were much worse; after nearly fif.. 10 years the former students could remember only eighteen percent of their classmates names. Names, for whatever reason, donot stick very well in our memories, or they stick only partway, causing us to call our brother-in-law Bob, Rob, or to mistake the author Ernest Hemingway for the actor Ernest Borgnine. Why should we remember faces, but not the names that go with them ?

How well do you think you can remember its features ? In a well-known test, two researchers, Raymond Nickerson and Marilyn Adams. 20 asked just such a question. The answer they got surprised them - and may surprise you. In the test, Nickerson and Adams asked twenty people to do something that sounds really easy: from memory, draw the front and back of a penny. After the drawings were done, Nickerson and Adams graded them to determine how accurately the participants had drawn eight critical features, like the placement of Lincoln's profile on the front of the coin 25 and the placement of the Lincoln Memorial on the back. The results wereA Of the twenty people tested, only one - an *avid penny collector 一 accurately recalled and located all eight features.

Interestingly, the most frequently forgotten feature was 30 the word “LIBERTY," which appears on the front of the coin, to the left of Lincoln's profile.

RHEED法の原理と得られる7つの情報が、この英文に書かれているみたいなのですが、よく分かりません。 分かる方助けてください!🙇‍♂️

INTRODUCTION Reection high-energy electron diHiraction (RHEED) uses a Rnely collimated electron beam with energy of 10-100 keV. The beam irradiates a sample surface with gazing incidence to obtain forward scattered difraction patterms. RHEED enables us to analyze structures of crystal surfaces at atomic levels and also to in situ monitor growth processes of thin films (mo、1988: Ichimiya and Cohen、2004: Peng et al.. 2011). From the arrangement。intensity and profile of the dilraction spots in RHEED patterns as described below in detail、 one can obtain various kinds of information: (1) the periodicity (unit cells) in atomic arrangements. (2) flat- ness of surfaces. (3) sizes of grains/domains of surface structures and microcrystals grown on the surface. (3) epitaxial relation between the grown flms/islands with respect to the substrate. (5) parameters character- izing structural phase transitions. (6) individual atomic positions in the unit cells. and (7) growth styles of thin films and numbers of atomic layers grown. The most important advantages of the method are that it is quite easy to install the RHEED apparatus in Yarious types of vacuum chambers without interfering with other components of apparatuses and to do real- time monitoring during thin-Rlm growths. Because of these advantages.RHEED is nowwidelyusednotonlyin research Iabs of surfaces and thin fims. but also in device production processes in industry Low-energy electron diiraction (LEED、see article Low-ENNERcy ErecroN DirscmoN)。 in which an electron beam of 10-100 eV in energy is irradiated onto a sample surface with nearly normal incidence to obtain back- scattered difraction patterns. is also widely used to analyze the atomic structures of crystal surfaces. Since one has to make the sample face directly to the LEED
