Födelseland: Holland Födelseår: 1872 Död år: 1934 Willem de Sitter föddes den 6 maj år 1872 i Holland. Han studerade vid universitetet i Groningen och tillbringade den största delen av sin karriär vid universitetet i Leiden där han hade hand om astronomiprogrammet. Observerade dessutom under ett kort tag med David Gill vid Godahoppsudden. Han arbetade mycket med jupitermånarnas rörelser och bestämde deras massor och omloppsbanor genom årtionden av observationer. Han återinförde astronomins grundläggande konstanter och bestämde variationen i Jordens rörelse. Utförde statistiska studier av fördelningen och rörelser hos stjärnor. Han är dock numera mest känd för hans bidrag till kosmologin. Hans lösning till Einsteins fältekvationer år 1917 visade att ett universum fritt från massa måste expandera. Senare fann de Sitter och Albert Einstein (1879-1955) en lösning med ett expanderande universum som inte är krökt. Modifierade Einsteins statiska teori inom kosmologin till en skenbart statisk teori och förutsade därmed att avståndet är proportionellt mot rödförskjutningen. Fick 1931 års brucemedalj . Dog den 19 november år 1934.

På denna sida finns länkar till alla dessa biografier samlade på ett enda ställe. Personerna är dels listade i både bokstavs- och födelsedagsordning men även efter nobelprisår (för de personer som har fått nobelpriset) samt i betydelsefullhetsordning för vetenskapen. Dessutom har jag nyligen lagt till Brucemedaljörer som är den högsta utmärkelsen inom astronomin, nobelpriset undantaget, samt Fields medalj som är matematikens nobelpris och som dessutom bara delas ut en gång vart fjärde år samt slutligen wolfpriset som är ett israeliskt pris som rankas steget under Nobelpriset men som ofta är åtminstone ett decennium snabbare med utnämningarna.

Policie nás chrání pøed terorem a patøí jí za to dík i ohleduplnost nás všech." Smrt a nemoci z cigaret nejsou legální tím, že je brání zkorumpovaní politikové, leckdy bohužel i prostou ignorací žurnalisté, èi lobisté tabákových koncernù. Smrt z cigaret je stejný teroristický èin jako kterýkoliv jiný a po duchu platných zákonù je veøejným ohrožením èíslo jedna. Což ví ostatnì i pan ministr zdravotnictví, jak nám vzkazuje na krabièkách, ale nikterak ho to nevzrušuje zøejmì?, nebo nechává cigarety dále distribuovat jako potraviny - v této souvislosti je smutné zjištìní, že žvýkací tabák neprojde.. Cigarety ano? Proè tedy cigareta není novokuøákùm zakázána, co hledá v kapitole "Potravináøský a tabákový prùmysl?" Co hledá na pultu každých potravin, ve skryté i otevøené reklamì. Dùmyslnou strategií tak asociuje zejména mladým lidem, že ono to zase tak hrozné není, to by to nedali do potravin, to by nekouøil ten a ten... Cigareta bez zábran hledá nové obìti a jejich nárùst u žákù základních i støedních škol je rekordní za poslední desetiletí.

Appendix 4: Brief Comments of Willem de Sitter and Albert Einstein On Curved Space [If you don't see "pi" (3.14159) displayed correctly in what follows, you probably have one of the older browsers. It's a problem that is discussed in Appendix 11 That space might differ significantly from a simple Euclidean model was hypothesized rather often in the first two or three decades of the twentieth century. The Friedmann models became popular in the mid 1930s, and the gravimetric considerations in those models seemed to indicate that space could be curved one way or the other, but probably not enough to affect its basic appearance as an expanding sphere within our Hubble horizon. We have traditionally been assumed to be "inside" this sphere, seemingly at its center - as any position would appear to be - with a "radius" currently thought to be around 13 to 14 billion light years in every direction. As we look back in time, we are actually looking into eras where the universe had not had as much time to expand as it has in the current era, that is, in the nearby universe. In fact, if we could look out far enough, the universe would seem to shrink to virtually nothing (or nearly so). This "virtually nothing" position is called the "singularity", and the conventional cosmological wisdom assumes that it is receding at the speed of light. You've probably never seen the universe depicted as anything other than an expanding Euclidean sphere, which still doesn't make it right and may be nothing more than improper Pavlovian conditioning.
