The discussion centers around two significant machines: the ENIAC, an early computer that was 10 feet tall, weighed 30 tons, and required 150 kilowatts of power, and the Russian Ekranoplan, a ground effect vehicle that could travel over 400 km/h and weighed 540 tons. The ENIAC utilized a vast number of electronic components but had less processing power than a modern pocket calculator. The Ekranoplan, developed by the Soviet Union, operates just above water using a shock wave principle, allowing it to travel over various terrains. The conversation also touches on trivia and historical facts about these machines, highlighting their unique engineering and capabilities. Overall, the thread showcases a blend of technical details and engaging quiz-like interactions.

Hmmm...are you sure about the invention of balances?

I found this site http://www1.fis.uc.pt/museu/mecclsing.htm that says this:
Balances had been constructed long before the theory of levers was completely understood. The balance with a pointer on arms of equal length and weights (instruments 14 to 16) comes from ancient times. From the third century BC it competed with the "Roman" balance which had a sliding pointer on a graduated shaft (instruments 18 and 19). The two kinds are known as drop-pan balances since the pans are below the pointer. It was Gilles Personne de Roberval who, in 1669, devised a balance with raised pans, kept horizontal by an articulated parallelogram. It was not until the 19th century, however, that Roberval's balance became widely used in shops and homes.

Oops...Black, it was , eh ? Nevermind. Evo's up.
No Moonbear guessed what it was. MB, take it away.

Good one Dex!

Evo, if you have a clue ready, you can take this one.

I had thrown scales & balances out as an answer because they've been around long before BC, but Dex is correct as far as being revolutionary to chemistry.

This thread sure moves fast. Three posts before I could correct myself !

Here's the story behind it all:

Back in the XI-the grade,my phys teacher said it and attributed wrongly to Lavoisier,and this was supposed to have happen ~1777/8.I took it and believed it and last year in November,when i was at a library at KUL,i read a 1935 book on Lavoisier in which this fact comes across:the young chemist Lavoisier read the book written by Black (maybe you can find the title) around 1750 in which Black described his experiments in which he thought of using a balance.

Then Lavoisier put this idea to good use...

Daniel.

P.S.Black was more of a physician than a chemist.

I have one ready; if neither of you (MB/Evo) minds ...

The reason it is a sucky clue is that every major early breakthrough in chemistry could accurately be described as a "revolution".

Fine with me...go for it.

Alright,i think Moonbear won it,unless any of you mentors want to change the replies...:-p

Moonbear,you're up.

In 1932 a 10-pack of this was packaged differently.

Obvious guess: chewing gum.

This can't be it, but being a BBQ type weekend, hot dogs and hot dog buns come to mind (maybe that's when they made it 8 hot dogs and 10 buns so you need to keep buying more packages?) :smile:

A 10-pack of Wrigley's gum was the first product to wear a barcode.

I'm going to give it to Zoovo.

Wow, that was quick! I missed the entire round :mad:

Bed time, night all x-x-x-x-x-x

Evo, you go.

I've got one.

The nuclear era was defined by this invention. The inventor credited was held prisoner by the Russians and forced to invent this.

No, but having one around this wouldn't be a bad idea. :-p

kryptonite :biggrin: :wink: I'm off...
 
  • #1,106
a hint - what it produces is bursts of atomic energy and splits in two easily

Dr.Gernot Zippe "The invention was the uranium centrifuge, and around the world, millions of them now spin in high-security plants often ringed by barbed wire."

I guess he was a common aquiaintance of mr.Kurchatov.

Daniel.
Correct!

I'll let Moonbear pick the challange.She owes one for her "balance":wink:

Daniel.
