Chiron and Achilles

In Greek mythology, Chiron ("hand") — sometimes spelled Cheiron or Kiron — was held as the superlative centaur over his brethren. Like the satyrs, centaurs were notorious for being overly indulgent drinkers and carousers, given to violence when intoxicated, and generally uncultured. Chiron, by contrast, was intelligent, civilized and kind. Sired by Cronus when he had taken the form of a horse and impregnated the nymph, Philyra, Chiron came from a different lineage than other centaurs. He was the father of Ocyrhoe with the nymph Chariclo and lived on Mount Pelion (or Pilion).

A great healer, astrologer, and respected oracle, Chiron was most revered as a teacher and tutored Asclepius, Ajax, Theseus, Achilles, Jason and Heracles. He had the gift of guiding his pupils to uncovering their highest potential and discovering their destiny. When the centaurs drank and partied themselves to extinction, Chiron became the last remaining centaur. His nobility is further reflected in the story of his death as Chiron sacrificed his life, allowing humanity to obtain the use of fire. Being the son of Cronus, a titan, he was therefore immortal and so could not die. So it was left to Heracles to arrange a bargain with Zeus to exchange Chiron's immortality for the life of Prometheus who had been chained to a rock and left to die for his transgressions. Chiron had been poisoned with an arrow belonging to Heracles that had been treated with the blood of the Hydra (see Lernaean Hydra) (in other versions, poison Chiron had given to the hero when he had been under the honorable centaur’s tutelage). This had taken place during the visit of Heracles to the cave of Pholus on Mount Pelion in Thessaly when he visited his friend during his fourth labour in defeating the Erymanthian Boar. While they were at supper, Heracles asked for some wine to accompany his meal. Pholus, who ate his food raw, was taken aback. He had been given a vessel of sacred wine by Dionysus sometime earlier, to be kept in trust for the rest of the centaurs until the right time for its opening. At Heracles's prompting, Pholus was forced to produce the vessel of sacred wine. The hero, gasping for wine, grabbed it from him and forced it open. Thereupon the vapours of the sacred wine wafted out of the cave and intoxicated the wild centaurs, led by Nessus, who had gathered outside. They attacked the cave with stones, rocks and fir trees. Heracles was forced to shoot many arrows (poisoned, of course, with the blood of the Hydra) to drive them back. During this assault, Chiron was hit in the thigh by one of the poisoned arrows. After the centaurs had fled, Pholus emerged from the cave to observe the destruction. Being of a philosophical frame of mind, he pulled one of the arrows from the body of a dead centaur and wondered how such a little thing as an arrow could have caused so much death and destruction. In that instant, he let slip the arrow from his hand and it dropped and hit him in the foot, killing him instantly.

Ironically, Chiron, the master of the healing arts, could not heal himself, so he willingly gave up his immortality and was placed in the sky as the constellation Centaurus.

Chiron saved the life of Peleus when Acastus tried to kill him by taking his sword and leaving him out in the woods to be slaughtered by the centaurs. Chiron retrieved the sword for Peleus. Some sources speculate that Chiron was originally a Thessalian god, later subsumed into the Greek pantheon as a centaur.


뭐 이렇다는거지 (근데 뭐가? ㅋ)

정리 그리고 계획


대학원 생활도 이제 마지막 학기구나...(한숨이 나오네 ;;)

학회 준비한다고 정신없이 8월달이 지나가고

어느덧 개강하고 일주일이란 시간이 금세 지나가 버렸다.

지난 여름 방학을 알차게 보냈어야 했는데, 

학회 준비한다고 방학동안 해야겠다고 다짐했던 것들 대부분이

결국 이번 학기 해야 할 것들의 목록에 합세를 하게 돼버렸군 (끄어 ㅜㅡ)

뭐 그렇다고 학회를 주최했던게 나쁘다는 것 만은 아니지만

얻은것 보다 잃은것이 더 크다고 느끼기 때문에

이번 학회에 대해서 아쉬움이 많이 남는건 어쩔 수 없나보다.


이번학기 논문쓰는거에다 QE준비하랴 명계작업까지

참 할게 많구나 ...(잠깐 마지막껀 아니자나 ㅋ)

역시 잠을 줄이는 수 밖에 없는게야 ...

먹을거라도 잘먹어야되는데 !

‘고체로 수소 저장’ 물질구조 발견

‘수소車상용화’ 한발짝 다가섰다

2006년 08월 05일| 글 | 김동욱 동아일보 기자ㆍcreating@donga.com |

수소자동차 상용화를 앞당길 수 있는 새로운 물질 구조가 국내 연구팀에 의해 발견됐다. 서울대 물리천문학부 임지순 교수 연구팀은 수소를 고체 상태에서 저장할 수 있는 물질 구조를 발견했다고 4일 밝혔다.

이 연구결과는 물리학 분야에서 세계 최고 권위의 학술지인 ‘피지컬 리뷰 레터’에 이날 게재됐다.

연구팀은 슈퍼컴퓨터를 이용해 수백 가지의 다양한 물질 구조를 설계하는 과정에서 플라스틱을 이루는 물질인 ‘폴리머’를 뭉치지 않게 분산시켜 ‘티타늄’ 원자를 달면 다양한 수소가 달라붙어 안전하게 저장된다는 사실을 발견했다.

연구팀은 “이런 구조로 상온·상압에서 수소를 저장하면 그 저장량이 2010년 미국 에너지부 목표치보다 25% 이상 초과할 정도로 획기적으로 늘어나게 된다”고 밝혔다.

수소자동차는 세계적인 자동차 회사들이 경쟁적으로 개발을 시도하고 있으나 수소를 가스 상태로 탱크에 저장하면 부피가 크고 폭발 위험을 안고 있어 안전한 저장물질을 찾는 것이 학계와 산업계의 오랜 숙제였다.

이번에 발견된 물질 구조를 수소자동차 상용화 개발에 응용하면 이 과제를 해결할 수 있다.

임 교수는 “이번 연구로 청정에너지와 대체에너지로 관심을 받고 있는 수소 에너지 개발 분야의 경쟁에서 유리한 위치를 확보하는

한편 세계적으로 경쟁이 치열한 수소자동차의 상용화에서도 한발 먼저 앞으로 나아갔음을 증명했다”고 설명했다.


연료전지에 관련해서 좋은 논문이 나왔나보네;;
내가 하는 연구도 돈벌이가 되는 결과가 나와야 할텐데 말야 ㅋ
