PREAMBLE

15

In order to he more fully cquippe1lto promote flevelopmcnt of the science of me<'hanics, the J nte rnal ion a I Committee for the Congresses of Applied Mechanics at its meeting at Paris in September 1916 decided to found a permanent organisation, called « The International Union of Theoretical and Applied Mechanics ».

This Union has been admitte•l into the International Council of Scien· tific Unions hy decision of the Executive Committee of this Council in 1917.

At the mcetinr;s at London in September 19-1-3 it was decided that the lntcrnntional Committee would continue to organise the Congresses of Applied Mc!'hanics as 311 irulepcndcnt hody as in the past. and that the International Committee would have the status of an a{lhering organisation of the Union.

The ohjccts of the International Union of Theoretical and Applied · Mechanics are :

a.) To form a link hctwecn persons ami national or international organisations engaged in sticntific work (theorcti<'al or experimental) in mechanics or in relatcrl sciences;

b) To •:oopcratc with the Inte rnational Commillec for the Congresses of Applied Mechanics when requc!'tcd, and to organi~c other international meetings for suhjcets falling within the field of theoreti cal and applied mechanics;

c) To engage in other adivitics meant to promote development of mechanics, both theoretical and applied, as a branch of science.

II

The active or,;an of the lnl<'rnational Union of Theoretical and Applied Mechanics is its Cr.neral Assembly.

The Cencral As!'cmhly has power to decide all questions affecting the Union, including alteration of the slnlntes. On specified question it may delegate this power to appropriate ho1lirs.

The composition of the Cencrnl A!<semhly is regulntecl in Article IV.

The tliscussions at the Symposium, both during the sessiom and on ot f1rr occasions, were very lively and t.o the point, since many, of the sci en· ti -t~ pre~cnt were acquainted with each other's ideas. The Symposium I ' OII ~C'lllelltly CO Uld lead to a COnsiderable deepening Of in~ight in SCVCral pwblcms concerning the motion of the interstellar gas and it brought a mnrke1l advance when compared with the preceding meeting, held at Paris in 1949, without which, however, the present results could not have been arhievcd. A matter of great importance was the, recognition of the decisive influence of gain and loss of energy of the gas through radiative processes, which has a great effect on its equation of state and consequently comes into c\·ery problem of motion. It has become clear that collisional pheno· mcna of a variety of types play a complicated role in the energy balance. Another point of great interest is the recognition of a new type of turbu­lcnrc, in whid1 an irregular collection of rompression and expansion waves forms the primary feature. This « compressional turhulcncc '> (in which ('hnnJH'~ of density nrc preponderant) must. be di~tinguishcd from the ordinary or <~: shear turhulencc », which is the type appearing in incom· prc~~ ihle fluids and which thus far has received most attention. In a com­prc~~ihle medium, one form is generated by the other one. In the interstellar gn~ it is the compressible tmbulence which probably plays the primary pnrt; it is caused hy the heating and ioni1.ation of the gas through the rndintion from high temperature stars, which heating has a random distri· hution in space and in time. ln conscqHcucc of the non-linear character of the equation!' governing the behaviour of the gas, shock waves are conti­nnnlly rJc,·cloping out of the system of compression waves; when shock wn\T~ mcrt in an npproprintc way, stronger !<hock wavrs r:nn be ger1crated, while on tl1e other hnrul dis~ipntion of energy through ,·iscous forces, thrrmnl conducti,·ity, electric and magnetic fichls, detract energy from the ~ h ock ,,.n,·cs. The stnt i~lil'al trcntmcnt of such a collection of shock waves will form an intcrc~ting, hut extremely rlifficult , problem for future work. It is pos~iblc that the cncrf!:y spectrum connected with shock wave turbu­lrrH·e will rliffer from the energy speetrum found in the case of shear I urhulcnr.c.

It is intended to puhli ~h the « Proceedings of the Symposium '>,

in a ,·olumc of s imilar size as that preparrtl after the Pari!~ Symposium. Again m11('h attention will he given to an atle'luatc re ndering of the discus· ~lOllS.

H. Second International Congress on Rheology (Oxford, 26-31 July 1953)

27

The Second International Congress on Hheology was organised by a Committee set up by the British Society for Rheology. President of the Congress was Sir Geoffrey I. Taylor, Cnmhrirlge; honorary secretary Dr. G. W. Scott lllair, National Institute for Rescnrclr in Dairying, Shinficld ncar Reading, who ~hared the burden of the organisation with Dr. J. G. Oldroyd, Dr. V. G. W. Harrison and Mr. F:. W. Geidt. A number of about 165 British, 80 overseas scientists and some 50 guests attended the Congress, the overseas members representing the following countries :

Australia, Austria, Brazil, Canada, F'rance, Germany, India, Israel, ltnl)', Jugoslavia, Netherlands, Norway, Sweden and United States of America. Six general lectures were given by invitcrl speakers, while 49 paper~ were read, distributed over three sections. Many discussions took place, both following the reading of the various papers and also informally on many occasions between the sessions. The Congress was a great success.

Two special meetings were devoted to a discussion on international organisation in rheology nnd on rheological nomenclature. As a consequence of the first mentioned discussion, at which also was present Professor N. F. Molt, president of the International Union of Pure and Applied Physics, while Madame A. Dobry-Dudanx represented the International Union of Pure and Applied Chemistry and Professor J. M. Burgers the International Union of Theoretical and Applied Mechanics, an International Committee on Rheology has hcen set up, with the following mandate :

I. To be a permanent body for organising future International Con· gresses on Hheology;

2. To encourage new national organisations for the study of rheology;

3. To net as eo-ordinating body in other international co-operations in the field of rheology.

The Committee provisionally was formed by : Prof. H. Weiss for Fran!'e; Prof. F. H. Miller for Germany; Mr. A.\,, Ward for Great Britain; Dr. H. N. J. San! for the Netherlands, and Or. H. S. Spencer for the United States. As further rncmhcrs were co-opted Prof. n . Gross for Bra1.il; Prof. M. Heiner for Israel, anrl Prof. A. Pclcrlin for Jugoslavia. The membership of the Committee is temporary, until the national societies can el~ct their own rcpres('nlati,·c~. IL was resolved also to send invitations to rheologists in the Sl'anrlinavian rormlries, in Indio ami in Japan, to nominate members for these countric~. Dr. H. N.J. Saal wa~ appointed as temporary secretary (address : Hoyal Dnt('h/ Shcll Lnhorntorie~, nadlmisw('g 3, Amsterdam-N.).

The possihility of some form of afriliation with one of the existing international ~rientific Unions was left open for the present.

As a result of the mccling on rheological nomenclature certain recom­mendations for collecting information on thi ~ suhject in various countries were ~cnt to the secretary of the lntemationnl Committee on Rheology.

During the Con~re!'s ll!rrr was nn ex l1i1Jition of rheological apparatus and a display of books on rheolo~y.

Free exdmnge of experience nnd tlrnught was eneouragecl hy such distinguished lea rned hoclies as the Ara· dernia dei Lincci, the Hoyal Society, tire Collegium Naturae Curiosorurn (Leopoldina ) and the Academic <les Sciences. The artivit y of these groups ~tirnulnted the formation of many other ar ndcrnics and sricutific societies iu the XVIJith and XIXth centuries. All these bo<lir.s n~surncd the respon· ~ ihility of encouraging nnd preserving knowlcclgc and ensured tire diffusion of new <lisroverics hy their puhlicalions nncl meetings.

Our century is marked hy the greatest expansion of ~r iencc irr human history : cxpnnsion of the nurnhcr of men engaged in rc!'eareh one! cxpan· sion in regard to countrirs rontrihuting to tire advan('cment of knowkcl:rr..

The fntc rnationnl Scientific Un ions, fonne<l after World War 1, reprscnt a form o f co-operation in science on the international !Orale, a .-n·operntion which hns hcen strikingly successful. Basing their efforts on the acti,·itics o f nationn l hodics they have tnken a ~ the ir drarge: a) the faci litation of relntions between scientists of different count ries, where internationnl co·opcrntion i!< useful; nrul b) the promotion of ~cicntific work in internationnl groups.

in 1917 aJI(l is S 1H0.00() now. This support has enabled ICSU and the Unions to enlarge their programs and to organise international meetings on a rather generous scale. It has had tire disadvantage that budgets had to be presented, for the benefit of UNESCO, so mudt in advance of actual plans, that those in chnrge of prcpn ring thc!<e requests were forced to imagine ncccls long before such needs existed and that there was never any certairrty ohout tire future .

Crowing ns it tends to tlo, ICS!I mrr~t lind o new organisation and admirri!'tration which will meet not only the present situntion, lmt will be appropriate ol!<o for fntmc development. I suhmit therefore lor general discussion a plan, which I hove devided irrto two parts, one being « General Prin ciples :~>, the other a « P roposed Solution » if these general prirrciples a rc nccepted. This solution is one among many others and could cosily be changed or modified in any way which would meet general approval.

Gt•llrral l'rirrcipln of lrrtcmntiorrnl Cooperation in Scicrrce

] . It is in the nature o( seicut ific erHicavour that new fields are disco· ,·erell, tlevelopcd, and hero me independent. The iuternational organisnt ion of !'eiencc must hove sueh a slrudrc thnt the~c new fields can he lilted into I he f ramcwork, without being snhmittcd to the patronising influence o( existing mcmhc:-rs .

2. It is nn old lmrnan ex perience that « { lnions » hnve to remain small, if they arc to work efficiently and mnin taiu tire eommunity spirit. For pur· poses o( coordirration and ndminist ration such Unions con always be joined into fedrrations, without lo!'ing their identity and independence, which is on imporlnnl !'l imulu!' for activity.

:1. Inte rnational Cooperation must receive its impulse from the acti vity of Unions who wish to work together ami wnnt to join their efforts. « Hoof organi~at ions » earr fnrilitale and rcali1.c such plans (or cooperation, hut they !<hould not plan « from the top ».

-1 .. The formation of International Unions is bnscd on the desire for intr.rnnt ion of ronpernt iou expressed hy national hodies or committee!'. These hoclics are rle!< igrraterl a~ « Nntional Atlhcring Orgnnisntions » and there ~horrid he one for each union and each r·onntry.

;\ ~ regards n, the delegates of the Unions would be elected by the t 1uion ; 11 ~ regards b, the delegates of the countries would be appointe(! by the central scienlific orgrmisation tl1rough which the country adheres to ICS ! I. ( N11tional He~earch Council, or National Academy, or other repre­~rntnthe scientiric hody.)

7. The f.cneral Assembl y of ICSU should meet only at rather long int!'rral ~ (3 or 5 years). It ~hould entrust tl1e actual work to a rather small nJHl competent Ex<'cutive Board.

B. The inlcrnntional organi~alion of sci ence should be a financial unit. Snh~niptions of a(lhcring countries should be collcctrd by /CSU. The amo1111l of snhscription of an adhering counlry should depend on :

n) Calcgory of membership of the country; b I Nmnhcr of scientific Unions lo whi ch the country is a(lhcr.ing. Provision must !Jc made that a country could a!'smne a different calc·

Catrg•Hy of country = 2. Number of Unions. to whieh rounlry is n•lhcring = 7. The country has a special interest in Crystallography and JS willing

9. Pla nning of intern ntional cooperation in science must be hased on the sciclitifie interest of a proj ect and not on the fa ct that money is availahle.

1. The whole present structure of Tnr r m ational Unions mu 1't he rcvi ~c,l. Some tin ions arc nctivc and vnlnflhle; others have out r,rown t.!Jcmsclve!', anrl nrc un~nti sfactory in tllf'ir present sl rttc; new Unions ha ve IH~en formed or nrc planned, hut cannot find a suitahle plaee in the present framework of ICSU.

REPORT 1953 31

General Principle 4 (referred to as GP. 4) states that th; Unions m_ust be based on the desire for their existence expressed by NatiOnal adhenng Organisations.

Proposition. - The maintenance or abolition of old Unions, an~ the formation of new Unions, must be decided by a discussion on the nat10nal scale first.

. For the gni£1ance of this discussion, ICSU should provide a definite plan for reorganisation.

2. According to GP. 2 Unions must remain small. Criteria for the new formation of a Union should he :

n) A recognised independent field of science; b) The organisation of its own international congress.

F'rom this point of view it is interesting to review the present Unions :

!All : no change. JUIJS : has 9 sections : Biometrics, Botany, experimental Cytology,

Embryology, Entomology, Genetics, Limnology, l\·1icrobiology, Zoology. Among these Botany, Zoology, Embryology, and Biometrics are indepen­

dent field s of science. Experimental Cytology, Genetics, and Microbiology are on their way to becoming independent, whereas Entomology belongs to Zoology and J .inmology is a borderline subject. A splitting up into 4-6 Unions seems indicatetl.

JliP;\C : has G ~f'clions : inorganic Chemistry, organic Chemistry, physical Chemistry, analytical Chemistry, biological Chemistry, applied Chemistry.

Among tlu~se inorganic, organif', phrsiral, and biological Chemistry are independent fi ehls of science. A splilling up into 4-5 Unions seems indi cated.

TUCr : no cha nge . IUGG : has 7 associntions : Geodesy, Se ismology, Meteorology, Ter·

rest rial Magnetism and Electricity, Physical Oceanography, Vulcanology, lly(lrology.

Here we meet an en! i rdy tli ffercnt s ituation . Seismology and V ulcano· logy, for example, arc just differ!'nl aspects or geophysical phenomena which are all interrelated. I must leave the problem o( reorganisation of thiJg ricld to tho~e who nrc more familiar with it.

JGU: no chan gr . llJIIS : no change.

IMll : no change. ltfT AM: no chnn ge. IUPAP : no Phange.

UHSI : no change.

:1. A llliiiJhcr of new Unions arf' now heing planned or are already in existen~'e, although still outs ide the framework of ICSU. These are :

Physhlogy, Biochemistry, P harmacology, Nutritional Sciences, Psy­cholo~v.

Final Rrmarks

The rontinual increa!'e of dcmnnds of (l(lmission from new Unions, the rigid attitude of old Unions towards these demands, the financial uncer­tainty of our relation~ with UNESCO, ami the fact that now ICSU and the Unions are obtaining financial ~upport from the same country through direct subscription and through UNESCO contributions, indicates that a reform is urgent.

Honorary officers mu~t he the bal'e of scientific organisations, they hnve given admirable service in the pa~t and will do so in the future. lnt.e rnational cooperation of Science must he placed, however, on a sound lm!<inesslike administration. This can only be done Ly spending a certain sum of professional secretariats. Crouping Unions into Federations has not only lhe arlvantnge of providing close scientifir contact, but furnishes an excellent opportunity to coneentrate and simplify administration and to save money.

K. ICSU Abstracting Board

Hnpport presente n Ia reunion du Comitc exccutif du Conseil International des Unions Scientifiques

(Strasbourg, 9-10 juillet 1953)

37

In Strnshourg, 011 July G-7, J95:l, ICSU Abs trncting Board, as it is at present constitute<l, will assemble for tlte firt st time. It seems thereforre necessary to sump up as l.ricfly as po!lsihle the past history and activities of th is organism.

Tlte Board enme into exi!'lence officially on June First, 1952. In fact its activity hn<l begun at n much cnrlier date (circa November 1951).

The re~ults obtainccl by the mnjor activity of the Board arc outlined as follows :

1. Autlwrs' Summaries

UNESCO's cleci!'ions and Hoyal Society Hules have been formally nccepted by nil periodicals printing papers on physic:s and published in the following countries :

- Unitecl Stnles of America; U. K. of Great flritain and Northern I rclancl; The Nctherlnnds ; Bclgiurn; France; Italy,

with the exception of a \'ery few publications printed in the United Kingdom. In each r-ase, the Board has communirnted with the Editor responsible

illtcl this person has acccptr.cl to verify that the ~ummaries prepared by their authors have correctly and clearly summed up what is contained in their papers.

2. l'agr-Proofs

Another importnnt measure taken by the Bonn! was to ask the publi!'hers of the more irnportnnt joumals printing papers on phys ics to forward n ~et of the final pn~c-proo fs of each of the ir i~sue to one or both of the eclitors of « Science Abstracts » and tl1e « Bulletin Analytique » du C. N. ItS. At the request of Dr. Crowtlter nn1l Dr. Ke rsnint, this action wns nt rirst restricted to n fex !"elcded jouruals in each country and, again at the rerJUC!'t of the snmc per~ons, has heen extended from time to time other journnls. The )!resent situntion is Sllllllllell "I' in the following list :

REI'ORT 1953 39

Published in Italy : - II Nuovo Cimento, - Alta Frequem:n, - Acta Pontifica Academia Scientiarium, Vat ican City.

l'ublisltcd in India : - Indian Journal of Physics, - Proceedings of the National Academy of Sciences (Allahabad), -- Proceedings of the National Institute o( Science of India.

A net result of our ndion has been to speed up considerably the appearance of the mo!lt important abstracts in the two journals : a delay from six to e ight weeks is tl111~ saved.

When only one set of the page-proofs (or other abstracts) is sent on hy a journal, this set is photocopied and communicated to the editor of both « Science Abstracts » and the ~ Bulletin Analytique du C. N. n. S ». The working of this has been, up to now, quite simple. It may become a little more elaborate when ICSU Abstracting Board has a greater number of member journals as at present. A regular exchange of page-proofs then have to be organised.

This las point may well come into discussion during t he Strasbourg meeting.

3. Coverage in Respect of Non-Periodical Journals

Measures have also been taken to deal with non-periodical publications. a) The Proceedings of varion~ physical societies in the world appear

from time to time at irregular intervals in the pages of some journals (A. J., Journal de Physique and Societe de Physique) . O ften these pro­ceedings give a short account of the papers which have been read at the meeting without speeifying whether these papers are to be published more fully Inter on in !'Orne journal~. Physical Societies have now been contacted nboul thi s question; hut it has been agreed that when the full paper is to be puhlishcd elsewhere, mention of th is la ter publi cation must appear in the ncr:ount of the meeting.

b) The non ·periodical publica tions which appear in France from time to time (Universities puhlil'ation~, govcmrnent reports and so on) will be reviewed hy the ·Editor of the French member-journal (the Bulletin Analy­tique du C. N. H. S.), Dr. G. Kersnint, who will send to the Editor of « Science Ab~t racts », Or. C rowther, the documents which, in his opinion ought to he nhstracterl.

For non pcriorlical puhlicntions printed in the United Kingdom, the same service wi ll he undn take11 by the crlitor o f « Science Abstracts » who will senrl to the rrlitor o f the « Bulletin Analytique » the documents which shoulcf he nhst rndcd.

On the reque!'l o f the ICSU Ah!'t rar"! ing Board in it ~ last Paris meetin g, action i!' now hcing tak f'n to extent! llti~ work to Northern countries. P ro­fe~sor B. l.i tulblnd has already been communicated with on this matter on March 16, 1953.

tlO INTERNATIONi\1. 11N IO N OF TIIF.O RF.TICAJ. AND APPLII::U MEOIANICS

c) From time to time collo!]uia and sympos ia nre orgnni!'cd under the nu!'pi ces of IUPAP. The General Secretary of IUPAP has agreed to ask the orgnniH•rs of all !'uch meetings to communicate to the Board at an early date nil documents regarding the organisation of the meetings and advnnce proofs of the pnpcrs to he read, if such proofs are printed; the ah!'tracting journals shoulcl he informed as soon as possible whether the papers arc to be publi!'hcd in a volume ( non·periodical publi cation).

The Board also rccommcmls that papers read at such internntional rnertings he published in one of the regula r journals or physics whenever possible. This recommrndntion ari!'rs out o f the nrce!'sily to avoid the multiplication of non ·pe riodical publications.

1. Ncgocintion.~ with tire Aut/rarities ur Germany

n) With the Physikalische Bcrichtc ns a potential memhe r Journal.

The Board hns received from the Association of Gcrmnn Physical Socicti e!' letters announcing officially thnt the German Phys ical Journal « l'h y!'ikalisrhe 13erichte » is resuming puhli ration. The Editor of « Physi­knli sche llcrirhtc » has also nnnouru·ed his intention to apply fo r rncmhcr­!'hil'lc ICSll Abstracting Hoard . The various rnrmhers of tlu~ Board have hccn mnsultcd on this po int. Their o pinion wns unanimo usly favournhle. Consequently, the editor of « Phys ikalischr. Berichtc » hns hecn supplied with thr drsirnblc info rmation about the Bonrd's nctivities and the services thi s nrganisn tion can rrrrdrr to it s memhrr.journals.

Following this the Vcrbnrrd Deutscher Physikalisdrcr l.e!'!'ehwhaftcrr a•·tin[: on behalf of the C< l'hysikalisr hc Bcri chte '> has fnrmnlly "I'Piird on .June 12. 195:\, for mcmhcrslrip o£ the lCSlf Abstractirr ~ l!oard.

Ph.ysics of _solids, conrluct ihility, semi·comluctors, theoretical phy!'ics, magnctrsm, opt1cs, cosmie rnys, thermodynamics, statistical mechanics, I]Uantir: theory of fields.

The help of tire Boarrl in t lti s matter has greatly and materially speeded up tlt e development of this project.

7. Clwmicnl Abstracting

For instance, the Board should pay « cotisations de Sccurite Sociale ~ according to the French Law, but cannot do so sillf'c in the eyes of this same Law there is no !>nch legal personality as the ICSU Abstracting Board, IUPAP has agreed, for the time hcing, to p_ay this money on our behalf, but the Crncral Secretary of IUPAP has recently a!'ked that the Doard take as soon as possible steps to put the situation in order.

d) In accordnr)Ce with the preceding remarks, the Doard of ICSU, after ha\·ing considered the matte r, recommended that ICSU Abstracting Board l>e given lr.gnl personality of it.s own in tlie same country as ICSU it !"clr, Belgium. In accorrlaru;c with this rccornmendntion , the Doard should clrart and adopt rules and by·laws which should govern its activities in the future.
