Euler mursten, primtalstrekanter og blinde matematikere. Matematiske julenødder.
Matematiske
”julenødder”.
Euler
mursten, primtalstrekanter og blinde matematikere.
Juletid er
hyggetid og familietid, så der er nogle opgaver med, hvor matematiske
forkundskaber kun behøves i mindre grad, så kan næsten alle være med.
1:
Google-opgaven, som er dels på grundskoleniveau, dels på gymnasieniveau.
Euler
mursten og to berømte blinde matematikere.
En Euler mursten – opkaldt efter den meget berømte schweiziske
matematiker og fysiker Leonhard Euler, (1707 – 1783) - er en kasse med
heltallige sidelængder og heltallige diagonallængder for diagonalerne i
sidefladerne.
Den mindste Euler mursten (mht. rumfang) blev fundet af en
tysk regnskabsmand i begyndelsen af 1700-tallet. Hvad er hans navn? Hvad er
Euler murstenens dimensioner//sidelængder? Nørde-søge-opgaven: Find et link til
en indscanning af den originale gamle tyske tekst, hvor dimensionerne på ”murstenen”
kan findes. Som det hedder på tysk: ”Ordnung muss sein”.
En blind matematiker (blind fra sin tidlige barndom) fandt i
første halvdel af 1700-tallet en parametriserings-formel for Euler mursten.
Hvad er hans navn? Find formlen.
Euler selv fandt mindst to parametriserings-formler for ” Euler
mursten”, (en af formlerne var måske identisk med den parametriserings-formel,
der hentydes til i linjerne lige ovenfor), angiveligt i slutningen af sit liv,
hvor han også var blevet blind. Find en af Eulers parametriserings-formler, som
ikke er identisk med den første formel.
Jagten på
den perfekte Euler mursten.
En perfekt Euler mursten er en Euler mursten med en
rumdiagonal, hvis længde også er et heltal. Eksisterer de perfekte Euler
mursten?
2:
Konstruktionsopgaven på det gymnasiale niveau.
Retvinklede trekanter i planen med
pythagoræiske tripler som sidelængder.
Betragt trekanten T i billedet nedenfor, der har følgende
egenskaber:
1: Den er retvinklet. 2: Dens sidelængder er
naturlige tal og danner derfor en pythagoræisk trippel.
3: Dens hjørnepunkter ligger i heltals-koordinatsæt. 4: Ingen af dens sider er parallelle
med x-aksen eller y-aksen.

Should Christians Vote for Roy Moore? A Pragmatic and Moral Approach | The Stream
Should Christians Vote for Roy Moore? A Pragmatic and Moral Approach | The Stream
"This, to me, seems to be both practical and moral. It does not minimize the charges brought against Judge Moore. It does not minimize the possibility of him being the victim of an attempted political take-down. And it does not allow last minute political shenanigans (if real) to subvert an important election. And, again, this ensures that Judge Moore and his accusers will have their day in court.

And, again, this ensures that Judge Moore and his accusers will have their day in court.
This approach, then, allows the voters to focus on the ideological differences between Moore and his Democratic opponent, putting aside the allegations of sexual misconduct until such a time that they can be thoroughly investigated.
Do you concur?" Quote: Michael Brown, see link.

"Comedian Gilbert Gottfried was so obscene that Fox News can’t even publish a highly expurgated version of his material, but part of his racist routine – filled with Asian sex jokes about Ann Curry -- included detailed remarks about Curry’s genitals."
