Science Trivia

[Timoleon of Korinthos]

Ok, my turn. Who was the first to come up with the idea of supercharging internal combustion engines?

 

[Sphere]

This is a shot in the dark, but was it Diesel? I cant recall his first name.

 

[Torment]

Vin...?

Kidding, you were thinking of Rudolf Diesel. But I believe it was actually Daimler who came up with the supercharger. Not quite sure though. Terrific invention though, has given humanity a lot of fun over the years.

 

[Timoleon of Korinthos]

Correct Torment! Well done +rep. Gottlieb Daimler patented the idea of super-charging in 1885 and he was also the first to actually construct a car with super-charged engine, one which used a Roots compressor, in 1912.

 

[Torment]

Ok boys, here we go again. What is the main characteristic that separated Enantiornithes from other birds?

 

[Nikos]

Easy, they had teeth and claws.

 

[Torment]

Wrong. Some modern day birds have teeth as well. Hint: think of skeletal structure.

Ah, the shoulder bones are reversed from those of modern birds. Damn, I'm losing my touch.

Correctamundo. Your turn.

 

[Nikos]

Ok, this will be an easy one. The Temperate rain forest enviornment can be found in only limited areas of the world, name one area where this rare ecosystem is found.

 

[Phier]

I never thought of the term temperate rainforest, I'm going to have to guess on the coast between/around Vancouver and Seattle.

Correct! Other areas include Chile and New Zealand.

 

[Phier]

What was the name of the substance, which prior to the discovery of the nature of heat, was thought to physically transfer to another substance.

Example. You put a pot on a fire. The theory was this substance came out of the wood, traveled through the flame and then entered the pot making it warm.

(P.S.) It will be 9 hours before I can reply again.

 

[Tankbuster]

Sounds like the phlogiston theory, that used to be very popular, but was rejected after the experiments of Lavoisier.

Close.

 

[Phier]

The caloric theory is an obsolete scientific theory that heat consists of a fluid called caloric that flows from hotter to colder bodies. Caloric was also thought of as a weightless gas that could pass in and out of pores in solids and liquids. The "caloric theory" was superseded by the mid-19th century in favor of the theory of heat but nevertheless persisted in scientific literature until the end of the 19th century.http://en.wikipedia.org/wiki/Caloric_theory#cite_note-0

 

[Timoleon of Korinthos]

Ok, since none got it and none bothers to pick up the quiz, I think I can ask a question.

Which statistical distribution is generally accepted as representing the variation of the velocity of the wind most accurately?

 

[♔Jean-Luc Picard♔]

Normal distribution.

 

[Timoleon of Korinthos]

No. Distributions used to analyse wind speed are not symmetrical.

 

[Saint Nicholas]

That would be the Weibull and Rayleigh distribution.

 

[Timoleon of Korinthos]

Exactly. +rep

 

[Saint Nicholas]

Thankyou. Here's my question.

How is it possible to see through glass?

 

[The Doppler Effect]

Thankyou. Here's my question.

How is it possible to see through glass?

It is possible to see through glass because it is technically a fluid and as such as a much less dense molecular structure therefor letting light through.

 

[Sphere]

Nah... I think its the Silicon-Oxygen cyrstalline structure. Like quartz its transparent because of the electron arrangement of one Oxygen bonded to 4 silicons. But thats the best I can do without googling. (and glass isn't perfectly transparent).

 

[Timoleon of Korinthos]

It is possible to see through glass because it is technically a fluid and as such as a much less dense molecular structure therefor letting light through.

But then why can't we see through smoke, which has even lesser density being a gass? I believe that we can see through glass because it does not absorb light, which is electromagnetic energy in its nature. Why it can't absorb light I don't really know, but I guess that the spaced energy levels of glass and the other transparent materials are such that their electrons can't ascend upon any of them by absorbing a photon and thus they don't, letting light pass through intact?

Not exactly.

[Saint Nicholas]

It has more to do with the size of the molecules, the molecules that make up glass are too small and too far apart to be able to stop light penetrating them. But your answer was the closest.

 

[The Doppler Effect]

Yeah, my turn

anyways, Explain how further dimensions could coexist with our known 4.

(if the question doesn't make sense just ask me to clarify)

Good Luck

 

[MrMofo]

theyre very very tiny and wrapped up in the calabai yau, um, spaces, of space

Close enough. Good job dude, first guess even. i thought i would get at least a page out of the question.
