퍼즐처럼 재미있게 수학 공부를 할 수 있다면 얼마나 좋을까?미국 미시간대 교육학과 켈리 믹스 교수의 최근 연구결과에 의하면 가능하다. 믹스 교수는 어린이에게 간단한 도형 맞추기 퍼즐을 시켰더니 산수 실력이 같이 좋아졌다는 연구결과를 미국 ‘인지발달학술지’에 발표했다.믹스 교수는 ...

우리나라 국가대표 축구팀이 월드컵 본선에 진출했다. 앞으로 좋은 성적을 거둘 수 있을지 많은 관심이 모아지고 있는 가운데, 주목할 만한 연구가 발표됐다. 최근 스페인의 한 연구팀이 축구 선수별로 예상 득점을 예측하는 방법을 발표한 것이다.스페인 그라나다대 경제학과 호세 마리아 베레스 ...

will not mix with water but be welded together.Then there are the coastal volcanoes to worry about, for they may be mixed up with ice ages that seem to occur every 23,000 years when fluctuations in Earth's orbit reduce the light reaching us from the sun. According to geologists Michael Rampino of New York University and Stephen Self of the University of Hawaii, when more ice forms on land, sea ...
the planet condensed to form our oceans, but on Mars, water apparently exists on the surface only in the form of ice mixed with carbon dioxide snow at the poles.Ever since good photos were taken of the arid Martian surface, scientists have struggled to account for what looks like evidence of the former presence of a good deal of water. The ground seems to be marked by old, dry river valleys. ...
a kind of soup today, but living organisms are present. In the original ocean soup, there were no organisms and the mix was thicker. It was out of this ocean soup that the first primitive forms of life appeared.Not everyone agrees with this picture of the origin of life but it has been a popular version, and we all know what an "ocean soup" is.However, even the ocean soup is not the first of ...
different-it is connected with the Atlantic ocean only by the narrow Strait of Gibraltor so that its waters don't mix well with the ocean. Moreover, it is a warm sea so that much water evaporates and this increases the solid content of what's left. Three times as much gold is found in a quantity of Mediterranean water as in the same quantity of ocean water. Maybe other land-locked bodies of ...
infallible after all. A certain small fraction of turtles get confused and end up at the wrong beaches. They breed and mix their nucleic acids with those who belong there. Even a small rate of "leakage" of this sort would wipe out most of the difference.The other possibility is that turtles in general are more flexible that we think. Forty thousand years ago, some may have accidentally ...
