ArcaVir minicontest - Questions

Packet switching was invented by Donald Davies and Paul Baran in the early 1960s. Some people claim that Leonard Kleinrock also invented packet switching, but Davies contested this prior to his death and pointed out that Kleinrock's research was actually in queueing theory, which is of course a key theoretical underpinning to packet switching.

Paul Baran (born 1926)

Kazimierz Siemienowicz, in the mid 17th century

translated to French in 1651, German in 1676, English and Dutch in 1729 and Polish in 1963.

i believe the first was 1650

I GOT IT FIRST vvvvv

 

Kazimierz Siemienowicz (ca.1600-ca.1651) [Multistage rocket]

Polish nobleman (coat-of-arms "Ostoja") from a family settled in Grand Duchy of Lithuania, military engineer and artillery specialist under Kings Wladyslaw IV [PL only] and Jan II Kazimierz [PL only] of Poland. Educated in part in the Netherlands, where he was sent by the King Wladyslaw IV to serve in the army of Duke Frederick-Henry of Oran during the war with Spain. From 1648 he served as Second in Command of Polish Royal Artillery, as an expert in the field of artillery and rocketry.

1650:
Publication of his fundamental work "Artis Magnae Artilleriae pars prima" ("Great Art of Artillery, the First Part") in Amsterdam (translations to: French 1651, German 1676, English and Dutch 1729, Polish 1963). It was used in Europe as a basic artillery manual for almost 200 years. The book contains a large chapter on construction, production and properties of rockets (for both military and civil purposes), including multi-stage rockets (see the figure), batteries of rockets, and rockets with delta-shaped stabilizers (instead of the common guiding rods). The manuscript of the second part was lost, together with its author, in obscure circumstances.

You can find more information on Siemienowicz in a story by Tadeusz Nowak "Kazimierz Siemienowicz, ca.1600-ca.1651" (in Polish), MON Press, Warsaw 1969, and in a preface to the Polish translation of his work (Warsaw 1963).

 

Just give me exact date so there will be no complains

Awesome, thank you!!! PM sent!

 

**** **** ****, again the question came to late... I even set my buzzer for it to wake me up... grrrrrrrrrrrrrrrrrrrrrr ((((((

 

Tomorrow I will try to come up with some really hard question that will be not that easy to answer using google so those people with slower connection will have more time.

 

This one wasn't terribly easy, I got several people connected to multi-stage rockets and had to sift through them to find what I hoped was the earliest. I had no idea such things were conceived way back then...a learning experience for sure

Oh, and for the contestants tomorrow, a tabbed browser helps, especially with multiple search engines open at the same time beforehand. Also, www.wikipedia.org is a fantastic resource in general.

 

Delete that post right now quexx88, or else! I am a kid you got to give me more help than others!

 

I'm 16, Firecat

 

Err...forgot that. But I'll still be younger than the other participants right (waiting to become 13)...

 

lol and I just got 18, and already a veteran... Served in Grozny...
