AI Thread Summary
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.

No offense,but the fire extinguisher didn't quite revolutionize chemistry.:smile:

Daniel.
But every chemistry lab has one (I hope)! I'm running out of ideas. Can you tell us whether it was an idea or a physical object?
 
  • #1,053
Both.The significance of that gesture/act was so great,that it changed everything in the world right now.Just like Faraday's 1831 electromagnetic induction discovery.

Any of Newton's ideas should be well-known, so that doesn't fit... Robert Boyle founding The Royal Society of London? Oh, that doesn't work either.

Oh, or what's that rotating thingamabob that spins the round bottom flasks when you evaporate solvents off your product? Is it simply called a rotating evaporator...something like that anyway.

Moonbear,as i said,it's not a technical question.You needn't be a chemist,or a math girl :wink: to answer it correctly.

I keep coming back to Cavendish. Was it his discovery of the constituents of water? His hydrogen generator?

Well, that's why I started my guessing with a stir plate! :smile:

How about the periodic table of elements? (Not sure if that has already been guessed; I skimmed through the two pages of guesses.)

Cavendish?I thought it was Priestley,but maybe it's just me...

Nope,Zoobyshoe,it's much easier than that.

This clue bothers me. Both lye and acid were in use pre-Gutenberg. The Chinese had also invented gunpowder well before Gutenberg

Okay, it revolutionized chemistry, isn't a chemical substance nor technical instrument but an act/gesture, is in every chemistry lab, happened between ~1463-1789, and the author and date may be difficult to find.

The publication of the first scientific journal?

Me too, I was a bit confused about the explosive gases thing.

It would be very Dex to give a load of cryptic random clues which don't actually lead anywhere, and see how long it takes for us to realize. :smile:

It's an object and this guy though of using it in his chemistry experiments.The gesture would be using it to ****** the g******* (curse) things...

He said it was an object.

Here are his hints -

They hadn't discovered corrosive substances,nor dangerous gases which might blow up.Daguerre was not born. And Gutenberg had already died.

Chemists would be dead without a ***************** in their lab.

I'm asking for the object,which should be the easy part,then the guy who did it and the year (with approximation) in which it happened.

Chemists would be dead without a ***************** in their lab.

It's really essential.You won't believe that simple it is. :wink:

"Revolutionized chemistry=It literally changed the way chemistry was (being) done".

It's not a chemical substance,but an object,INSTRUMENT,if u prefer.

YES. :approve: Not "analytical",a simple balance to weigh the substances.Can anyone provide a name and an approximate year for it...?

Need i say the importance of having a balance in a chemistry lab...? :rolleyes:

MOONBEAR wins round one. :-p

That explains a lot!

I googled it.

The clue about revolutionizing chemistry made me think immediately of Lavoisier, who was executed during the French Revolution. But I can't think of any object he invented...

Following the object line of reasoning led me to Celsius (who likely fits the timeline) but was really an astronomer...

Galvani was a bio guy, and I can't think of anything he invented...

Ummm...nothing else comes to mind...
 
  • #1,080
Oops...Black, it was , eh ? Nevermind. Moonbear's up.

PS : Thought of the physical balance, but imagined that was there before medieval times...
 
  • #1,081
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.

No Moonbear guessed what it was. MB, take it away.

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.

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

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

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:
 
  • #1,097
A 10-pack of Wrigley's gum was the first product to wear a barcode.

I'm going to give it to Zoovo.

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.
