aefibird Posted February 8, 2005 Posted February 8, 2005 This can work a bit like those Q & A sections in newspapers - y'know where a reader asks a question and someone else writes in with a reply. Are there any questions that you want answering?? If so, post em here and hopefully someone will be able to answer for you. I'll get the ball rolling with a qestion of my own. Why are there holes in Swiss cheese (Emmentel) and how do the holes 'get' there? "Was it really worth it? Only time and death may ever tell..."

Shorinryu Sensei Posted February 8, 2005 Posted February 8, 2005 Why are there holes in Swiss cheese (Emmentel) and how do the holes 'get' there? Check out this site..has darn near everything on it! http://www.howstuffworks.com/ However, that site didn't have anything on Swiss cheese..so I went to Google andhere ya go! "A search on "swiss cheese holes" revealed that gassy bacteria are behind all that holey cheese. In order to make cheese, you need the help of bacteria. Starter cultures containing bacteria are added to milk, where they create lactic acid, essential for producing cheese. Various types of bacteria can be used to make cheese, and some cheeses require several different bacteria to give them a particular flavor. Propionibacter shermani is one of the three types of bacteria used to make Swiss cheese, and it's responsible for the cheese's distinctive holes. Once P. shermani is added to the cheese mixture and warmed, bubbles of carbon dioxide form. These bubbles become holes in the final product. Cheesemakers can control the size of the holes by changing the acidity, temperature, and curing time of the mixture. Incidentally, those holes are technically called "eyes," and the proper Swiss name for the cheese is Emmentaler (also spelled Emmental or Emmenthaler). Swiss cheese has been in the news recently because the U.S. Department of Agriculture (USDA) created new guidelines that regulate the hole size of domestically produced Swiss cheese. The USDA reduced the standard size of the holes by half because new cheese-slicing machinery got caught on larger holes. The Swiss weren't pleased by the revised guidelines and insist that Emmentaler must have large holes. Considering how iconic those eyes are, we think they have a good point."

isshinryu5toforever Posted February 9, 2005 Posted February 9, 2005 I can't say I am absolutely positive as I am not a science major, I believe though that it has to do with changing the amount of a certain type of pigment within the mixture. Blue has a chemical or pigment in it that reflects blue and absorbs other colors. Yellow has a pigment that absorbs yellow, but reflects all others. By mixing these two, you are creating a pigmentation mixure that will land somewhere between yellow and blue and that just so happens to be green. Thus, the new pigment reflects green and absorbs all other colors. It has to do with the visible light spectrum. If you look up the visible light spectrum you will notice that red is on your far left and violet on your far right. As you move from left to right you notice that red becomes yellow, and on the other side moving left, violet becomes blue. They meet and create green. It is just the way that our eye happens to pick up the reflected light. He who knows others is wise. He who knows himself is enlightened.- Tao Te Ching"Move as swift as a wind, stay as silent as forest, attack as fierce as fire, undefeatable defense like a mountain."- Sun Tzu, the Art of War
krzychicano Posted February 9, 2005 Posted February 9, 2005 That is a very thorough explanation. Thnx! What the superior man seeks is in himself; what the small man seeks is in others. - Confucius
Sam Posted February 9, 2005 Posted February 9, 2005 another explanation: If you take the wave length of yellow and blue and take an average (mean) you get green... voila, its that simple.... sort of Its actualyl a bit more complicated but thats pretty much the answer i think you're looking for
aefibird Posted February 11, 2005 Author Posted February 11, 2005 Anyone got any more "burning" questions?? "Was it really worth it? Only time and death may ever tell..." The Beautiful South - The Rose of My CologneSheffield Steelers!
Freddy Posted February 15, 2005 Posted February 15, 2005 i do.... how does gravity work? is it like a huge magnet woych attacts everything? Extraordinary abilities can only come from extraordinary effort
steveb Posted February 15, 2005 Posted February 15, 2005 There is no gravity...the Earth sucks Res firma, mitescere nescit
Nick_UKWC Posted February 16, 2005 Posted February 16, 2005 Do you really want to know how gravity is meant to work...because it's a tad complex! (I'll give it a go if you like though lol). On the paint thing, yes it's the wavelengths that give you the colour you see, but a yellow object doesn't reflect everything apart from yellow, it ONLY reflects yellow, hence you only see yellow I have a question!
