FOREWORD REAMHRA Ta breis is 1,100 tionscnamh curtha ar aghaidh cheana f6in ag micleinn iarbhunscoile ins na ceithre Thaispeantais Eolaithe Oga a tion6ladh 6 1965 i leith. Mas suntasach ann fein a lion na dtionscnamh is mo na sin a neagsulacht. Ni hamhain go raibh ina measc priomhranna uile na heolaiochta nadurtha, ach b'eigin ar dha bcaid na ranna sin a roinnt i rann6ga breise.

Ta os cionn 150 duals bronnta ins na com6rtais seo cheanna fein (dualseanna do "Eolai Og na Bliana" san aireamh). Ni leor na hiomaitheoiri eile a share chun duals a bhaint amach oir d'fheach paineal moltoiri ceimiula chuige go mbeadh ar gach duaiseoir caighdean airithe a shroisint.

Do cldidh leis sin o shoin agus minic go leor b'eigean gan duals a bhronnadh I ranna airithe den chombrtas toisc nar shrois aon iomaitheoir an caighdean a leagadh amach.

Mar sin to dha chomhartha feabhais ag rith leis na duaiseanna-bua san iomaiocht agus ardchaighdean.

Nior eirigh leis na tiortha nar ghlac morphairt sa reamhloid tionsclach a scar choir a dheanamh i bhforbairt na heolaiochta o shoin.

Td roinnt den mhini6 air sin le fail sa mbru chun fail a thagann mar chuid den dearca tionsclach fein. Ni haon eiseacht I Eire; nlorbh aon taca dCinn an gne seo dar stair.

Nuair a fuaireadar an deis, afach, leirigh pobal Eireann a nachmainn chun freastal ar re seo na tionsclalochta. Sampla is ea bunt agus fas Aer Lingus. Td go leor comharthai fais Bile le fail i ngaiscl na neolaithe oga seo.

Bainisteoir Ginearaita.

In the four Young Scientists' Exhibitions that have been held annually since 1965, more than 1,100 projects were entered by pupils of our post-primary schools, If this figure is impressive in itself, the nature and variety of those projects were hardly less so: not only were the principal branches of the natural sciences fully represented, but it was twice necessary to refine categories by introducing new classifications.

Including the "Young Scientist of the Year" awards, which were made on each of four previous occasions, upwards of 150 prizes were won by other competitors. Mere relative merit, however, was not enough to win them: the fact that projects were adjudged to be first in their own categories did not necessarily mean that they deserved prizes. From the outset, our distinguished panel of judges rightly insisted that a minimum standard must beset and reached.

This standard has been maintained ever since and awards have been withheld in not a few instances where the best projects in particular classifications failed to attain the required level of excellence. Thus, the prizes won by our young competitors have had the double distinction of competitive superiority and inherent merit; and those that have been awarded at the present Exhibition are likewise distinguished.

Countries that were outside the main stream of the Industrial Revolution were ill-equipped to contribute to, or even keep abreast of, the advancements in science that characterised the end of the 19th and the beginning of the 20th centuries. This is understandable: rapid industrialisation is a well-known forcing-bed for human skills and knowledge. Ireland has been no exception: the course of history was not conducive to our development in this regard. Given the opportunity, however, Irish men and women have shown that they are capable of meeting the demands of this increasingly technological age. The formation and growth of Aer Lingus is one example of this capacity. The achievements of our young scientists provide many more and encouraging examples.
