Dinosaurs disappeared 65 million years ago 6500 Dinosaur
- Slides: 19
Dinosaurs disappeared 65 million years ago. 恐竜は 6500万年前に絶滅しました。 Dinosaur specialists are not scientists, but diggers. Hence they do not care for a scientific approach. 恐竜発掘者たちは、科学的な研究推進は苦手であった。 彼等が思いついた恐竜絶滅の説明は: Possible explanations その理由とされたのは • DNA deficiency, 1934 UK DNA欠陥の進行 • Hormone deficiency for reproduction, 1970 ホルモン異常のため子孫ができなくなる。 • Sun’s activity change >> cold climate 気候変動 • Ozone layer destruction >> too much UVL オゾン層の破壊から、過剰な量の紫外線が到達 • Poisonous plants 有毒な植物の繁茂 And so forth. などなど

Mikhail Gorbachev; “Models made by Russian and American scientists showed that a nuclear would result in a nuclear winter that would be extremely destructive to all life on Earth; the knowledge of that was a great stimulus to us, to people of honor and morality, to act. ” Nature 473, p. 275 (19 May 2011) 25年後になって、ゴルバチェフ元首相は、核の 冬という結論が人道的な世界の動きを推進したこ とを認めた。(ネイチャー誌2011年5月)
• Scientific discoveries must be backed up by proofs acceptable to everyone. • Scientists could work together because they can trust each other, even across different research fields. • Geologist >>> Physicist >>> Chemist >>> Astrophysicist >>> Meteorologist >>> Military specialist >>> Politicians
Scientific Evidence presented with proofs can be very persuasive! 実証に基づいた科学の検証は、人 々を確信させることが出来る。
